Thies, Extension Horticulturist) Since 1936, this periodical has been issued by the Extension Service as a means of informing Massachusetts fruit growers on matter of current interest. Both tree fruits and small fruits have been included. The first mimeographed issue in March, 1936 was preceded by carbon copies of similar material mailed from time to time to the Coimty Extension offices. (Two of these releases, July and August 1935, are here included). It has been our purpose through the years to cover a wide variety of items and to have the write-ups relatively brief. Considerable attention has been given to abstracting Experiment Station reports and to the presentation of timely information. A casual survey of this material, month by month, will provide the reader with a running account of the various problems confronting the fruit grower in years past and the suggested solutions. For various reasons, there are quite a number of missing issues in this bound volime. In several of the months no issue was prepared. In others, a demand for the extra copies exhausted the supply. The missing issues are as follows: 1936 (Jan., Feb., March, April, July, Aug., Nov., Dec); 1937 (Aug., Sept., Oct.); 1939 (Oct.); 19A3 (Aug.); 1946 (Feb., Nov.,);194-7 (Jan., Majs June, Sept.,); 194-3 (Jan., Mar., May, Sept.,); 1949 (Jan., JC^^, June, Sept, Dec.,). rfoftf rrr* jL uiooe /-ilo J ' January 18, 1945 Prepared by the Fruit Prograiii Coixiitt^e of the Extension Service T/T.

A minimum thermometer in one of the College peach orchards registered -17 F. on the 20th and -19'-*F. on the 21st. As a result, fruit buds on all but the most hardy var- ieties were completely killed. On such hardy varieties as Oriole, ilarigold, Greensboro, and Buttercup there are probably less than b^j of live buds, in nost cases only a very fev;, scattered over the tree. Signs are also develop- ing that there may be considerable wood injury. ien over the state, information irom peacn grov/ers 3ir\jrchards would be welcome. It is suggested that I jareffil survey of the condition of the fruit buds and m Lt buds should be sectioned on shoots and short spur- | Not enough reports are available to determine how extensive the in- jury to peach trees has been over the state. Information from peach grov/ers about the condition of the each peach grower make a a wood in his orchard. Fruit buds should be sectioned on shoots and short spur- like grovrths, in the tops, and around the bottoms of the trees. Also enough shoots and branches should be cut to determine the extent of any wood injury. A generous sample of trees v;ell scattered over the orchard should be checked. Such a check-up follov;ing v/inter injury is particularly important before prun- ing is started because the kind and amount of pruning v;ill be determined large- ly by the extent and severity of the injury found. Any grower v;ho wishes to have a sample of peach buds checked for him, may send a sample of shoots and spurs to the Pomology Department, French Hall, M. S. C, This kind of a check-up is necessarily limited and therefore not so good as one made by the grower himself right in the orchard. J. S, Bailey PEACH PRUNING It is time to be thinking about peach pruning. Under normal condi- tions, it \;ould be advisable to leave the peach pruning until just as late in the spring as possible and then rush it through. By doing this, any vdnter in- jury is given as much chance as possible to show up. Then the kind and amount of pruning can be adjusted to the extent and severity of winter injury. Because of the labor shortage, it is going to take careful planning to delay the peach pruning without delaying it too much. Also that check up of the orchard condition (see Cold Injury to Peaches) bociimes even more important. If injury to the wood is severe, the trees will probably recover much better, with no pruning. Thus much labor can be saved. If the fruit buds are all kill- ed but the vj-ood is not injured, it is a good time to lov;er the trees by cutting back the tops. This can be done by a fevi large cuts, omitting detailed pruning, thus saving labor. If there are a fev live buds on th-s tree, the pruning should be light to save as much as possible of v;hat will be a small crop anyway. J, Li. Bailey The time has come ivhen a boatload of food is just as necessary as a boatload of men or munitions. A carload of food produced in Massachusetts releases for military purposes a carload produced elsewhere. ■M0 ^7S "\J \^ \t ^ _. That food prodviction in Great Britain has increased about 50;o since the VvTar began? This increase has been attained in spite of the fact that practically all able bodiediiEn of draft age have been taken into the armed forces. That about 13;,^ o! our 1942 food production was used for nilitar^/ and Lend-Lease purposes? About a year ajo it vjas thought that only 3 or 9Ja would go into those channels. That at least l/4 of all the food produced in the U. S. in 1945 will be used to feed our soldiers and allies? Estinates for 5 comi-aodities are as follows; Red meats, l/4; lard, l/3 ; eggs, l/o ; dairy products, l/cJ; canned fruits and vegetables, l/2. That about l/3 of the people in the United States are so situated tiiat they could be more or less self supporting? In other words, they could produce a large proportion of the food needed for home consumption. That the last 10)j increase in national food production should and can be obtained by producing for home use? Llost farms can make a definite con- tribution to the food production program by having a garden, a few hens and one or more meat producing animals. That if all of the new farm machinery available in 1943 could be dis- tributed to best advantage and used efficiently, it would account for only 2jb, of the needed food production? The other 98^'o must be produced by machinery now in use. That the manufacture of power sprayers in 1943 is limited to Z-d)o of that in 1940-41? It is reported that sprayer manufacturers v/ho have 90/j of the materials on hand will be permitted to purchase the other 10> to complete the manufacture of spraying equipment. There is raore need this year than ever for completely overhauling present equipment, replacing all needed repair parts. Dealers in spraying equipment report many orders on hand with certain replace- ment parts very scarce. That 24 of the 3070 counties in the U. S. (less than .8 of If.) used 12;;o of all fertilizers put on the land in a recent year? Aroostook County, Maine, used the most, 111,446 tons spread by 487u fanners. -4- That the 26,000,000 tons of manure produced annually on Kev/ York farms carry 12 times as much nitrogen as v;as sold in commercial fertilizers in that state in 1940? Yfith tremendous quantities of nitrogen needed in making munitions, it is our patriotic duty to conserve farm manures and utilize them to best advantage in the food production program. That it is the present policy of the Federal Government to support the prices of agricultural products at a sufficiently high level to encourage the production of those crops necessary for maintaining the food supply of our armed forces, allies, and our people on the home front? These crops include meat animals, oil producing crops, and the feed crops required to maintain an increased production of livest -^ck products. That fruit production in the United States in 1942 was the largest on record? ¥('ith the exception of prunes and apricots, the 1942 crop of all major fruits was above the 10-year average. The coiTimercial apple crop in the United States amounted to 127,655,000 bushels compared with 122,256,000 bushels in 1941. That packing boxes and crates made in the United States in 1942 used 9,000,000,000 board feet of lumber and 200,000 tons of steel? In the State of Washington 110,000,000 board feet of luiaber were required to make boxes to ship the State's 27,500,000 bushel crop of apples. That the European red mite, v.'hlch caused so much bronzing of apple foliage in Massachusetts last siiimier is neither a chewing, nor a sucking insect? In fact it isn't even an insect, having 8 legs instead of 6. The so-called spider mites, according to 1'.. D. \Tnitcomb, v;ound the surface of the leaf and lap up the sap \;hich emerges. They can feed on liquids, only, but do not have a hollov; beak such as aphids thr )ugh which the sap can be pumped. Instead, they have small, sharp appendages with which they pierce the tissue of the leaf. That erosion has already ruined about 14^j of the land surface in the United States? At least 75;^ of our cultivated area has a sufficient degree of slope to b'i classified as definitely subject to erosion. L. Southwick That yield per acre is tremendously important in successful orchards today? In a IiiclTi"^n~t'u"d;7Tt was found that a group of "successful" grov/ers attained an average annual yield of apples amounting to 317 bushels per acre, while a group rated as "unsuccessful," attained only 161 bushels per acre over a 0-year period. It is not enough to produce good apples. In these times, growers must produce good crops of good apj)les. L. S, That from 25 to 55 million pounds of avocados are consumed arjiually in the U. S.? Of this amount California produces about 55>b, Florida 15/a, and Cuba 30^j. Although this fruit is an important item in the daily diet of Cen- tral America and adjacent territory, it has achieved fame in the U. S, mostly as a salad fruit. L. S. That a coffee substitute made from apples, dried, roasted, and ground, has been introduced in Canada? This nevf product sells for much less than coffee and is reported to be quite popular. That the flesh of aii apple breaks down in cookin^j only if an acid is present? A sv/eet apple, lacking, the acid of a tart apple, retains its firroness and shape when cut into slices and cooked. For this reason the Deli- cious is less suited for apple sauce than the Baldv.dn. That there are aBoat 23,000,000 men in the U. 3. between the ages of 18 and 38? Of this number it is estimated that 8,000,000 will be physically- disqualified for military service. Of the remaining 15,000,000 about 10,000,000 will probably be in the armed forces by the end of 1943. That the American Forestry Association has records of five tree species of v/nich one or more individuals tovjer at least 200 feet? Tallest trees on record for the five species are: HedVf'ood, 300; Sequoia, 272; Douglas Fir, 221; Red Gum, 200; 3ugar Pine, 200, Alaska has a Sitka Spruce wliich measures 204 feet. That the Agricultural Marketing Administration purchased 2 75,048 bushels of apples in Lias sac hu setts last fall? Purchases involved mainly 3 var- ieties,- Baldwin (177,272 bu.), Mcintosh (55,408 bu.) and Cortland (21,779 bu.). Nearly 8,000 bushels each of Delicious and Wealthy and smaller quantities of Sta^.iian, ?l. I. Grecnin^_. , Rome, Viagener, and Snow i.-ere also sold through the A. M. A. Six counties participated in the program (Middlesex, T.'orcester, FraiUclin, Hampshire, Essex, and Hampden) v/ith sales ranging from 173,653 to 2,745 bushels.

Quoting from his letter of January 11, "These apples were shipped to various State Commodity Distribution outlets for school lunch programs, institutions, and direct relief. Due to limited outlets, 50,526 bushels went into storage to be used later, chiefly in scliool lunch programs."

This is one more possible explanation for the recent increase in the prevalence and severity of this trouble in com- norcial orchards in this state. It is suggested that in orchards v/here s^Tiip- toms of magnesium deficiency have been observed, the use of potassiuia in the fertilizer program be discontinued, at least temporarily, ITliere soils are very acid (and most i^Ias sac hu setts orchard soils are), v/G suggest the application of high-magnesiun limestone. The magnesiujn in lime- stone is only slov/ly available. Tlie use of some soluble compound such as mag- nesium sulfate (Epsom Salts) probably v/ill bo more quickly effective in correct- ing magnesium deficiency, though the tir.io required may be two or more years. Experiments along this line are under\/ay and it is hoped tiiat recomiiiendations based on results ■•>£ this i/ork can be made vdthin a reasonable time. L. Southwick CITRUS FERTILIZER PROGRAI'J A successful citrus fertilizer program consisting of three separate applications per year is outlined in a recent armual report of the Florida Agricultural Experiment Station. The analysis of each application is as follows: Nitrogen - 3^o, phosphoric acid - 6'}o, potash - 8%, magnesium oxide - 2%, manganese oxide - 1%, copper oxide - l/2^^. Dolomite is used to maintain the soil at pH 5.5 to 6.0, and copper-zinc sprays are applied. Thus a complete fertilizer, instead of the usual N-P-K designation, looks like this: li-P-K-Mg- Ivln-Cu-Zn. There is also some evidence of isolated cases of deficiency of iron and boron. Other s;\Taptoms of malnutrition have occurred but have not been diag- nosed. ilo such complicated fertilizer program is required for orchards in L'lassachusetts . Ilov/ever, it is becoming increasingly evident that the program may become more inclusive as time goes on. The recent diagnosis of magnesium deficiency in apples and the previous findings of boron shortage, point the way toward a more balanced and hence inclusive fertilizer program for Massachusetts °^"°'^^^^^' L. Southwick CjiAiraEs^_ra jnn^_i943_ apple spray chart The more important changes in the newly revised apple spray chart for 1943 are as follov/s: (1) Lead arsenate is recoi.imended in only one of the pre-blossom sprays. Previously it was included in botii the pre-pink and the pink sprays. (2) Lime sulfur no longer appears among the recommended materials. Instead, it appears as a substitute for wettable sulfur in one of the Notes. Its use under certain weather c 'Uditions may occasionally be advisable. (o) A high calcium lime appears in the list of materials for the first time. Pre- viously the use of lime was discussed in one of the Notes. (4) As a means of controlling a severe outbreak of red iiite, ^ne of the DIT materials is recom- mended as an emergency application.

With its sprawling tangle of growth, it may look hopeless. Yet you may find the magic wand of productiveness within easy reach. An hour's work with the pruning shears, a few trellis repairs and tvro or three well-timed sprays or dusts will vrork wonders. Lus- cious grapes for the home table are your revrard next September if you pay attention to three or four essentials. Suitable Supports are Necessary. If your vine is already sup- ported by a trellis" or arbor', your job is partly done. It is quite impos- sible to keep a grape vine productive if it must attach itself to a tree or building, or if it lies on the ground. Two horizontal wires, about three and five feet above the ground, are quite ideal. An arbor is also satis- factory if the vine is well pruned each year. Whatever the support, a tangled vine can best be pruned by first cutting it loose and laying it on the tjround. Annual Pruning a Vital Factor. Fruit buds are found only on last year's growtlu Prunlng~'re'duces "the number of these fruit buds to a practical limit, eliminates much of the older v;ood and stimulates nevr fruiting wood for next year. A vine which has 500 fruit buds v;ill bear larger clusters if at least 80^J are removed in the pruning process. This is best done, not by trimming off the tips, but by selecting a few grov^ths of the previous season (characterized by their lighter brown color) and by cutting the rest of the vine away. Don't be afraid to make an occasional large cut in order to re- move an older portion of the vine. What vie retain is more important than what we cut off. Thin the vine heavily instead of "giving it a haircut." TOien completely pruned it will look discouragingly thin. An amateur might consider it ruined. The real benefit from pruning, however, is seen when we compare the crop of grapes on well pruned and unpruned vines. The import- ance of thorough, annual pruning can scarcely be over- stressed. If pruning is properly done, in March, the current season's crop is profoundly affected, and the vine will develop good fruiting v;ood for the next season. A Third Essential, - Pest Control. Fev/ vines are highly successful without some attention" 'to disea'se~and insect control. The most common dis- ease of grapes in Massachusetts is Black Rot which causes the grapes to turn brown in midsummer. Later, they turn black and dry up, resembling raisins. Copper sprays or dusts will control this disease, powdered Bordeaux or copper-lime dust may be obtained from most dealers in spray materials. If rose bugs are numerous, special control measures are needed. Fertilization Not Always Needed. Pruning is generally more essen- tial than fertilizing becaiTse the average^ vine growing in a good soil is al- ready sufficiently vigorous. Pruning further invigorates the remaining parts of the vine. If stimulation is needed, a garden fertilizer, barnyard manure, clean cultivation, or mulching are recommended. A mature grapevine, hovjever badly neglected, offers promise of a crop next September, while a new vine set this spring, will require three to five years to come into bearing. -3- That about 1,600,000 farm workers in the U. S. left the farm during 1942? Of this nunber 331,000 v/ere operators and managers and 1,234,000 were family workers and year-round hired workers. Industry took 921,000 and the armed forces 694,000. That certain materials applied to pruning v/ounds do more harm than good? Shellac is satisfactory. So is v/hite lead paint. Bordeaux paste is very efficient in preventing v/ood rot but lacks permanency. Compounds con- taining creosote tend to injure the cambiujn, and therefore retard healing. That fewer apples v/ere shipped to the Boston market from out of state up to January than in any year on record? The total volume v/as at least 10^ more than last year and was divided approxLmately as follov^s: hone grown apples, 650,000 bushels and shipped-in apples, 125,000 bushels. That wood ashes are an excellent source of potassium and lime? Chem- ical analyses show that they contain approximately 5% potash, 2;. phosphoric acid and an acid neutralizing equivalent aiaounting to 66^o of a high grade agricultural limestone. . That the average water content of apples is 84.1^and that the average freezing point is 28,4° F.? For long storage life, the ideal storage temper- ature is 51 to 32° F., and relative humidity at least 85 to 88^-o. The harvested apple is a living organism with a more or less definite span of life. If it "lives too fast," either before or after picking, the time it remains in good eating condition is shortened proportionately. That fruits develop considerable heat during the ripening process? Apples held at 32° F., generate about u60 b.t.u. per ton per day (a b.t.u. is the amount of heat required to raise the temperature of one pound of water one degree F.). At 85° F. about 6600 b.t.u. 's per ton per day are generated. For Bartlett pears, the difference in heat generated at the tvio temperatures is even greater. This so-called heat of respiration is a direct measure of the rate of ripening. That apples are a more expensive crop to grov; and market in dried form than either plums and grapes? Apples must be dried artificially. Raisins and prunes are the result of drying in the sun. This is one reason why raisins can be produced for as little as 5/ per pound. That 80^ of the 12 million bushel apple crop in VJenatchee County, Washington was harvested last fall by local people? Schools opened three weeks early to permit closing during the harvest season. Stores closed part -4- of the week and many local people who had not handled apples previously, in- cluding vfives of business men, did their share in picking and packing the "bumper crop. In the same way, ITev; England apple growers must utilize to the fullest extent all nearby labor resources instead of hoping for an influx of migratory labor. That as many as 450 European red mite have been counted on a single leaf? In one orchard the average on 100 leaves was 225 per leaf. The nev; DN material was tried in New England last summer by six investigators in six different localities. In a series of 22 tests the average reduction in num- ber of mites amounted to 97^0. That the root of a tree is more spongy in texture and lighter in weight than a branch largely because it has relatively more vessels and fewer fibers? The root functions mainly as a conductor of materials in solution. The branch must also be strong enough to withstand high winds and support a heavy crop of fruit. That February is an ideal time to (1) overhaul farm machinery, (2) make further progress in pruning and removal of unv;anted trees, and (3) order fertilizers, seeds, and other supplies? That the large average size of apples in Massachusetts last fall vms not entirely due to abnormally heavy rainfall during the growing season? A study of daily weather records up to harvest time indicates a fairly good dis- tribution but not an exce.ssive amount of rainfall. At the same time vreather conditions preceding Mcintosh harvest v;ere apparently highly favorable for fruit sv;elling. Higher than normal humidity and more hours of sunshine pre- vious to harvest time may have influenced the size of fruit. About 70^3 of the Mcintosh crop in storage is reported to be 3 inches in diameter or larger. That apples and field mice are common items of food for foxes? In a study of the food habits of 289 red and gray foxes taken during the winter season in New England, it was found that 128 (M.2%) had eaten ap-ples, while 83 (28.6^) had eaten field mice. These two items of food v;ere exceeded in popularity only by cottontail rabbits. It was found that 173 (59.8^o) had eaten rabbits. That the use of fresh, native grown fruits and vegetables in Massa- chusetts this year has released more than 35,000 refrigerator cars which othenvise v/ould have been required to haul this class of food products into this area? I That raw apple is sometimes beneficial in the diet of an infant? In the Mich. State Hort. Soc. Rept. (1939) v/e find this statement, "Investiga- tions have found the rav/ apple diet successful v;ith infants less than 6 months of age." That it requires more than 3 times as many peaches of 1 3/4 to 2 inch diameterto weigh 50 lbs., than of 2 3/4 to 3 inch diamoter? Of the smaller size, 340 peaches are required, and of the larger size only 110.

Rollins, Extension Horticulturist, University of Connecticut, Storrs, Conn.) -5- RUSSETIIIG JF GOLDEN DELICIOUS The tendency of fruit of the Golden Delicious apple to russet is one of the weaknesses of the variety. It makes the fruit less attractive and is related to its tendency to shrivel in storage. Russeting seems to be worse in the humid East than it is in the less humid or semi-arid regions in the V/est. From Maine comes a suggestion that there may be another factor involved. Observing differences in individual trees, scions from high russet- trees v/ere grafted into trees with low russeting and vice versa. Under Maine conditions there seemed to be a persistency in the new location, of the ten- dency to russet. If yau have any individual Golden Delicious trees that seem especially free from russet, the writer would be glad to know about it. It would do no harm to propagate from such trees. j, j{. shaw RELATION BECTffiEN DATE OF BLOOM MD DATE OF HARVEST A recent discussion of the time of ripening of fruit varieties advances the idea that the date of full bloom gives a basis of calculating the date of harvest. The data for some of our principal varieties are as follows; Days from Bloom to Harvest Shortest Longest Average Baldwin 134 138 135 Cortland 125 130 128 Delicious- 129 134 132 Early Mcintosh 88 94 90 Golden Delicious l32 140 138 Gravanstein 110 120 114 Mcintosh 124 129 127 Northern Spy 138 144 143 V;ealthy 103 116 109 This means that Baldwin, for example, will be ready to pick about 135 days after full bloom. Doubtless summer temperatures and cultural con- ditions modify this interval; a season warmer than usual v>rill shorten this period and high nitrogen v;ill lengthen it. These data are for Geneva, Nev/ York. The interval may differ somewhat for Massachusetts and would not be exactly the same for different parts of the State. Hoivever, it seems worth v/hile for a fruit grower to note the date of full bloom and consider it in planning the date of harvest. j, Yi. Shaw PLANNING FOR THE NIT.T ORCIiARD If you are planning to set a new orchard this spring, the first thing to do is to see that the site and soil are suitable. Since this is a fairly long-time investment that you are about to make, these two points are highly important. Second, why not consider contour planting of the orchard? There are several possible advantages of contour planting of or- chards and, frankly, one or more disadvantages. Among the advantages are -6- the holding of soil, fertilizer, and moisture, and the saving of tractor fuel. A disadvantage is a restriction in the movement of heavy implements through the orchard, which can be only on the contour or level and not up and down the slope. But this restriction frequently develops in orchards on sloping land after a number of years whether or not they were planted on the exact contour. It is not uncommon to see old orchards in which crude bench terraces have developed, which practically prohibit movement of ve- hicles and implements up and dovm the slope. Then, why not plant on the contour and have these terraces develop in the right v/ay? The possible saving of soil and fertilizer on cultivated sloping land is obvious. But it is frequently pointed out that orchards, especially apple orchards, are nov; kept in sod and therefore would not benefit from contour planting. However, young apple orchards are often cultivated during the first fev; years of their development, and during that period they stand to benefit from the conservation of soil, fertilizer, and moisture, and later when in permanent sod they may benefit from the saving of moisture and fer- tilizer. In about one out of every three or four years additional soil moisture will improve the crop. There is a terraced peach orchard at the Massachusetts State College. V/ithin a dry spell in the summer of 1940 the soil in this orchard was found to contain a little more than tv/ice as much moisture as was found in adjoining land which was not terraced. Practically all the rain that fell during the dry spell cajne in flash shovrers and was held on the terraced slope, whereas mueh of it ran off the non-terraced slope. Contour planting of orchards is comparatively simple and easy. If interested in this method, consult your county agent, the extension horti- culturist, or the undersigned, — A. B. Beaumont LIIJE AND tlAIJUKE "Lime and lime v/ithout manure, make both farm and farmer poor," is an old rural proverb that expresses a basic truth. Both materials or their equivalents are needed to build and maintain fertility. They ere most commonly added to the soil separately, and that is the most fool-proof method of application, but now that farm labor is one of the biggest problems of production the question may well be asked if these tv/o soil amendments may not be spread together. Some pertinent data bearing on this question have come recently from the Vermont Experiment Station. They shov/ that ground limestone may be mixed with both fresh and fermented cow manure with scarcely any loss of ammonia. Caustic lime caused no loss in fresh manure, even lessened it in some cases by delaying amnonif ication; but it did expel some ammonia from fermented manure. Even in the latter case the authors of the report think that the saving in time and labor may offset the loss of ammonia. Perhaps the most important factor in saving the ammonia of manure is moisture. At 20° C. a given volume of water \iill dissolve about 700 vol- umes of ammonia gas. If manure is kept v/ell moistened there is little danger of ammonia loss, but if it is allov/ed to dry, lime or no lime, the ammonia loss may be considerable. This point emphasizes the value of plowing under -7- of harrowing in manure as soon as possible after applying, or of spreading it in rainy weather. Both forms of lime, but particularly the caustic forra, accentuate the loss of ammonia on drying. Superphosphates on the other hand, particularly the lower grades containing 18 to 20^^ of phosphoric acid, retard the loss of ammonia by fixation. Gj'psuin, which makes up a considerable pro- portion of the low-analysis phosphates, chemically absorbs ammonia under certain conditions. __;^. b. Beaumont MORE ABOUT COLD INJURY TO PEACHES Since the last report in Fruit Notes, a fev/ peach grov/ers have sent in reports v/hich indicate very close to a complete crop failure in Massachusetts. Occasionally an orchard has 5 or perhaps lO^o of the fruit buds alive. (This statement was v/ritten before the cold spell around Feb. 16.) Tv;o growers have reported v/ood injury. Further observations at the College revealed only slight injury to the tops, but severe injury to the trunks of some trees. In these injured trunks the cambium and outer sapwood vjere brown. In a fevi, the bark also had been injured. Since the trunks of the trees are the last part to "harden off" in the fall, they are especially susceptible to winter injury following a late v/arm fall, such as occurred in 1942. Last fall the trees were kept grovdng later than usual and the "hardening off" of the trunks was delayed. The cold spell of December 20 and 21 caught the trunks only partly "hardened off," and injury resulted. Peach growers will be v;ise to look for trunk injury and keep close watch of any injured trees for they v;ill probably need special treatment later. A small elliptical piece of bark cut from the trunk will reveal what has happened and probably do the tree little harm. j. s. Bailey PRUNING Y;iNTER INJURED PEACH TREES It is becoming increasingly evident that most peach orchards vdll have no crop this year. Therefore, in those orchards without a crop, now is a good time to lower the tops of any trees which are becoming too tall. Any branches which are too long and rangy should be cut back. Cutting to a side branch in tv/o or three year old wood will reduce the tendency to sucker. After all weak, injured and dead v/ood is removed, further thinning should be done if necessary. In orchards v/here there are still live fruit buds, a thorough checkup is desirable to find out v,rhere these buds are. Then the parts of trees, or parts of iiae orchard, which shovi signs of bearing some fruit should be left unpruned so as not to cut off any part of the small crop. The rest of the orchard should be given a light but thorough thinning out. If the wood of top or trunk has been injured, a light but thorough thinning out will induce plenty of new wood to form fruit buds for next year. Trees which have had theirwDod severely injured had better be left unpruned. They usually recover better that way. However, they v/ill benefit from light fertilization and good care through the summer. j, g, Bailey ORDSR BEES EARLY According to the latest advice received, shippers of package bees are experiencing some difficulty in getting necessary supplies for shipment cases. It appears likely that the number of packages shipped will be below normal. Beekeepers vrtio intend to use package bees are advised to order early. Fruit growers who rely on package bees for pollination should take this ad- vice and act on it. It is very likely that losses of overwintered bees virill be larger than usual. This, together with the shortage of package bees that may be anticipated, makes it essential that arrangements for securing bees for pol- lination be completed early. — F. R. Shaw SALVAGE AIJD RE-USE OF FRUIT AIJD VEGETAB LE COMTAIMERS General Lumber Situation. The users and suppliers of lumber in 1942 were caught in a sxjueeze because of increased demand for lumber as a result of the larger .amounts necessary for military uses and to decreased production which resulted from labor and equipment shortages. As a result of the in- creased demand, the estimated consumption of lumber in 1942 went up ll^-j over that of 1941. Also in 1942 the production of lumber failed by about 20^i to equal consumption. The deficit v/as made up by imports and by v/ithdrav/als from inventories. This drain upon supplies has now depleted the stocks of lumber to about 50^b of normal. Considering the fact that the inventory re- serve represents a v;ide variety of sizes, species, and grades, this small stock represents a very siTiall supply for emergencies in 1943. By exercising the severest restrictions, it is estimated that con- sumption in 1943 can be held to a little over 31 billion board feet, which is about 25J^ belov; the consumption of last year. Although it is possible to reduce the lumber consuraption for certain uses during 1943 from that of the past year, increases for other uses will be inevitable. These are chiefly for boxes and crates used as containers for products shipped overseas. Other military requirements, such as construction, are expected to drop. It may be necessary to restrict civilian construction this year to about one-half that of last year and to about one-third of that of 1941. This restriction would eliminate all but the bare essentials of construction and maintenance. Even with tliis restricted use, hov/ever, it is possible that labor, equipment, tire and replacement problems may reduce the 1943 produc- tion and imports below the requirements of these minimum essentials, and thus make further inroads upon the already scanty lumber reserves by the end of 1943. This makes any program for conserving lumber during the cur- rent year of vital inporteince. Fruit and Vegetable Containers. The total estimated minimum es- sential requirements f oV~6n1^iners~'and~~shipping material, such as boxes, crates, etc., has increased about 30^o for 1943 over the consumption of 1942. Most of this increase has been for military shipments. Some materials are being packed in v/ood containers because of the scarcity of other package materials such as metals. Other types of supplies are- being put in wooden packages in order to secure a more substantial contairter for overseas shipping. i -9- Fruit and vegetable producers will likely be able to get along with a slightly smaller quantity of wooden containers in 1943 than was the case in 1942. Assuming 1942 packing practices and per-acre production, and the 1943 goals, the total number of board feet of lumber to package the 1943 crop v;ill be about 1% less than that required in 1942. This will probably be further reduced through the use of containers of substitute materials and limited shipments of products in bulk. However, these adjustments can- not be sufficient to offset possible shortages of container material and increased container demands for military shipments, and thus avert a tight package situation. Used Containers. One method of supplementing the tight fruit and vegetable container situation is by the careful salvaging and reuse of second- hand packages. Every salvaged used container made available for reuse makes a number of contributions to the general supply situation and the war effort. One of these is the fact that this container may package a product which nay, in an acute container situation, not be made available to consumers. Another, the use of the salvaged package will release to other uses labor and equip- ment which would be necessary to make another nev/ box or basket. In addition, it will release such critical materials as wood and metal to be used in other war activities. The salvaging of used containers offers real possi- bilities. For instance, there are enough board feet of wood in 1,000 sal- vaged apple boxes to crate an average airplane for overseas shipment. There is enough metal in 60 wire-bound orange boxes to supply the nails and straps for crating a jeep for overseas shipment. One thousand wire-bound citrus boxes have about 500 pounds of metal. Thus, if a quarter of the 18 million new wire-bound citrus boxes used each year were salvaged and reused, it would release 2,250,000 pounds of metal to be used for such vital war activ- ities as the making of shells, tanks, and guns. This saving also benefits the fruit and vegetable growers as difficulties are being experienced in securing supplies of wire and nails for packages. Extensive work is already being done in salvaging used containers in certain large markets. A recent survey by the Viar Production Board in- dicates that .approximately 25^^ of all wooden fruit and vegetable containers v;hich are shipped into Hew York City are salvaged. This varies greatly among the various types of containers, the percentage being very high for such packages as baskets and much lower for nailed boxes. This custom seem^s to be general. Used or second-hand containers are more extensively used by grov/ers in the nearby or market garden area* than in the distant producing districts because of the difficulty and expense of shipping used containers to distant producing centers. Thus, crates, baskets and other packages which are shipped into the large consuming centers are salvaged and sold to growers in the nearby producing districts. Some estimates indicate that as much as GOJo of the vegetables grovm in the Chicago market garden area are marketed in second-hand containers. The proportion, of course < becomes less as the distance from the city increases, but information recently col- lected by Cornell University indicates that grov;ers in some of the interior counties of New York State are depending on used containers for as much as 35^ of their total package requirements. In the larger cities used containers are collected by a number of agencies. Farmers who live in the nearby districts collect a portion from -10- the retail stores direct. Jiany peddlers collect the empty containers from retailers and restaurants. Second-hand dealers or "junkies" arrange v;ith trash collectors to separate the containers and scrap pieces from the other material. The largest group collecting used containers consists of chain stores. Used package dealers buy containers from the "junkies," peddlers, and chain stores and sort them into the various types. These dealers also repair damaged packages and remake others into types more generally in demand. The dealers resell these sorted and repaired packages to farmers in the nearby districts, or to large second-hand wholesalers who may distribute them into the market garden districts of adjacent cities or to other production centers. The remaking of other types of containers from such packages as orange and apple boxes has become an established business in the larger cities. From material in these boxes, crates are made for the packing of cabbage, beans, carrots, onions, and other vegetables. Reconditioning, as well as remaking, is an important enterprise. Reclaimed pieces of contain- ers, second-hand nails and wire t.re used to repair dai.iaged hampers, baskets or covers. A second-hand v.'ire handle, a bent nail or tv/o, with a salvaged slat, v/ill many times restore a useless damaged container to good condition. In addition to collecting, remaking and remodeling, careful hand- ling by all dealers all along the line to prevent needless damage is im- portant. Many parts of potentially good containers which might be used are thrown on fires in the markets on cold mornings* Attention to all of these factors in regard to used containers will increase the supply of fruit and vegetable packages and perrait the use of material, which v;ould otherwise be required for new containers, to be used for other vital uses. Therefore, the program which is operatiiig rather smoothly in the large cities should be expanded and similar types should be developed in the smaller centers. TliE VICTORY T.^ H. P. Gilmore of IVestboro submits the following joint ruling recently issued by the Bureau of Internal Revenue and the Vfar Labor Board. "(1) The paj^ent by an employer of tlie five percent Victory Tax on behalf of his employees v.'ithout deducting it from the employees' pay is a wage or salary increase requiring the prior approval of the Board or the Commissioner pursuant to Executive Order No. 9250 and the Regulations of the Director of Economic Stabilization* "(2) On January 23, the Commissioner of Internal Revenue issued a ruling interpreting the Revenue Act so that vrhere the National Yfar Labor Board or the Commissioner of Internal Revenue avmrds or approves an increase in wages or salaries retroactive to 1942, the tax need not be withheld on that portion of the increase v/hich is applicable to v:ork performed in 1942. "(3) Vihether the five percent tax will ultimately be collected on such retroactive pay is a matter to which the Congress may give its attention during the current session." Quoting from Hr.

Area Victory Gardens THE FRUIT GRCHTER Alfl) THE FOOD PRODUCTION PROGRAM Fruits are recognized as an essential part of our diet. In dried form they are an important item of food for our armed forces abroad and for our fighting allies. Fresh fruits, being less easily exported, contribute in a similar way to our food needs here at home. Every good fruit grower has reason to feel that he is making a contribution to the food production program. This applies to the commercial fruit grower and to the producer of fruits for home use as well, Whatever we grow of necessary foods, near the point of consumption, releases transportation facilities for vital use elsewhere. A carload of good apples grovm on a hillside farm v.rithin easy trucking distance of Boston, Issued by the Extension Service in furtherance of Acts of Hay 8 and June 30, 1914, VJillard A. Ilunson, director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. is directly in line with our v;artime economy. It vrould be folly for the owner of a good apple orchard to go into some other line of business and neglect the orchard. The experienced fruit grov/er can make his greatest contribution to the v;ar effort by taking the best possible care of his fruit planting. If every fruit farm utilizes its resources to best advantage, there will be no need of transporting from other producing areas, the Suits needed for home consumption. Most of our needs along fruit lines can be supplied from the New England area, ¥/e are constantly being reminded that American farmers must produce more food. From the standpoint of the fruit grower, this does not mean more bushels, without regard to grade or quality. Yj'e already have too many "cull" apples. In the writer's opinion, our job is to produce, not more apples, but more good apples. Vie should aim to produce aji apple crop of which at least 905,0 wTrr"grade U.S. No. 1 or higher. Apples of lower grade are of doubtful value, even in peacetime. They become a liability in v/artime when storage facilities, packages, labor, etc., are scarce. Ii'^e ought not to clutter up our markets or our storages v;ith fruit fit only for feeding to livestock. 1/Vhat should be the attitude of the home gardener who is interested, not in producing fruit for sale, but for the home table? Again it should be pointed out that the owner of a small piece of land should concentrate first on vegetables, and should expand to include small fruits only if garden space and tiae are availile. Small fruits offer much more promise of success for the backyard gardener, than tree fruits. We cannot afford to imste valuable land, fertilizers, spray materials, etc., without reasonable assurance that the investment will produce something of real value. The producer of fruits for home use should consider very carefully the factors upon which success in the hone fruit planting depends. Patriotism does not demand that we spend time and money in trying to produce usable apples on an old tall tree, when the same area might produce an abundance of strawberries or of vegetables with less expense. Massachusetts fruit growers are doing more long time planning than ever before in order to economize on labor, materials, aaid equipment. The food production program will be a success from both the commercial and the home garden standpoint if we limit ourselves to those food crops v/ithin reach of our available resources. By so doing, the fruit grovrer will make his biggest contribution to the national food production program. ORCHARDS DAI'JAGEU BY SEVERE WINTER VJEATHER If a definite relationship between winter temperatures aind injury in plant tissues were to exist, we v/ould expect heavy damage in Massachusetts or- chards as a result of the near record cold spell around February 16. The extent of injury, hovrever, is dependent upon the maturity of the tissues and perhaps upon the date and duration of the damaging temperatures. The injury in Baldwin trees this winter, although very noticeable, does not seem to be as severe as in the winter of 1933-34. A partial killing of the sapwood is apparently more common than damage to the bark and canibiura. As more Baldwin trees are examined we are finding considerable brovming of the sapvrood, par- ticularly in the lovrer limbs. In most trees, hov/ever, there seeias to be enough -3- sapvrood to enable the tree to outgrow the damaged condition. The pith of the twigs and spurs, where part of the food materials are comrjionly stored, shows rather severe daiaago. LIuch less loose bark is in evidence on apple tree trunks than in 1934. Not until the end of the 1943 growing season can we make anything like a reliable estimate of the extent of damage in Massachusetts orchards. It will probably vary tremendously in individual trees, and no one cultural practice will facilitate recovery. Vfinter injured trees cannot be "pruned into a normal condition." They may be better off with little or no pruning. Mulching will be beneficial, and if the cambium, inner bark and sapwood are reasonably intact, added nitrogen or perhaps strip cultivation will tend ,-' to encourage the development of new tissues. In the College orchards severe iyury has been observed on sweet cherry trees. Some of them are apparently beyond hope of recovery. Peach trees also show uranistakable damage, A no pruning program for such trees is strongly recommended. Only time will tell which trees or parts of trees are capable of making satisfactory growth and (barring another cold winter) of bearing a crop of peaches in 1944. "READY TO BEAR" FRUIT PLANTS V/lienever we consider buying fruit plants which, according to the claims of the nursery, v;ill "bear the first season," we ou^ht to ask ourselves whether such performance is an advantage or a disadvantage. Is the apple or two, borne the first year, of prirae importance? Should we look for^^ard to harvesting a few strawberries a month after setting the plants? In general, is early bear- ing conducive to success in a fruit planting?- The ansv/er is definitely "No." All blossoms should be removed from newly set strawberry plants because any berries borne the first season will endanger the growth of new plants for next year. A strav/berry plant cannot mature berries and at the same time de- velop strong runner plants, since the same rav^ materials are required for both. Raspberry plants should be cut back to a height of 6 or 8 inches at planting time in order to prevent fruiting, and thereby encourage a strong grovrth of new canes. Otherv;ise, the crop of fruit will so tax the root system until mid- summer that the growth of nev/ canes for next year vdll be retarded. Only a severely stunted or a true dwarf apple tree can be expected to bear the first year. If the tree does bear so early it is a sure sign that it is making very '^ scanty growth.' With few exceptions, a fruit plant needs the first season to become established and to make vigorous vegetative growth, instead of exhausting its food resources in bringing fruit to maturity. If v/e focus our attention on early bearing, and overlook the kind of growth necessary for future production, we are horticulturally shortsighted. TAKE GOOD CARE OF YOUR SPRAYER.

TBffiLY NOTES ON THE BEE SITUATION Since fruit growers are vitally interested in bees for pollination, the following summary of the bee situation by F. R. Shaw of the Dept, of Entomology, is presentedi Massachusetts beekeepers are faced with greater responsibili- ties now than at any time in the recent past. They must keep their colonies at maximum strength in order to produce the vi&x and honey necessary and have adequate pollination of our fruits and many vegetables. Last year we were asked to double the honey crop. V/e failed to do this partly due to the season and partly due to the fact that many colonies were not properly attended to because of lack of time and other reasons. This year vw are asked to increase the amount of honey produced, to increase the supply of beeswax by one third and we may be faced viith additional demands for bees for pollination, especially in view of the increase of Victory gardens. In view of the greater responsibilities facing the beekeeper, better planning will be necessary during the coiiiing year. Bee supplies are limited. A quota of 57^o has been established for hives and Z^% for other supplies based on the manvfacture of hives and supplies during 1940 and 1941, This makes necessary more careful checking of equipment. It would be well to have re- placements on hand before discarding any old equipment. If you must secure new materials, place your orders ag soon as possible. -5- f Package Bees. Package bee shippers are faced with the difficulty of obtaining wire cloth, tin feeding cans, and sugar. It is entirely possible, therefore, that shipments of package bees may be below normal this spring. If you plan to use package bees, it will be necessary to place your orders early. Price Ceiling on Beeswax. It is of interest to note that a price ceil- ing has been placed on beesvmx and this was issued as of November 13, 1942. A cash price of 41,5 cents per pound or 43.5 cents per pound in exchange for supplies is the maximum allov;ed for crude domestic beeswax. Early Examination of Bees Desirable. Due to the difficulty experienced by some in secur"ing~"sugar for feeding together with the presence of a large amount of honeydew stored last season, it can be expected that the winter loss of colonies may be above normal. Colonies found to be lov>r in stores can be fed or doubled up v/ith other colonies having more food. If the colonies are low in pollen, soybean flour containing not over 5^o fat can be given as a substitute. AGRICULTURAL INSECTICIDES FOR 1945 Although smaller supplies of some insecticides may be obtainable this year due to the war, the nation's farmers will still be able to carry on a suitable insect control program if conservation and substitution practices are follov/ed. The following report is based on a study made by the Food Re- quirements Committee (novif Food Advisory Committee) of which Secretary of Agri- culture Claude R. ITickard is chairman. Insecticides included in the report are arsenic, cryolite, rotenone, pyrethrum, nicotine sulfate and copper. The only real shortages, the Committee points out, exist in the sup- plies of rotenone and pyrethrum. Estimated supply of rotenone is placed at 3,600^000 pounds, with 1943 requirements likely reaching 4,225,000 pounds. A supply of 16,000,000 pounds of pyrethrum is on hand but 17,250,000 pounds of this insecticide will probably be needed this year. Supplies of arsenic, cryolite, nicotine sulfate and copper chemicals seem to be sufficient, or the possibilities of increasing the 1943 output is believed good enough to assure adequate amounts of these materials for use as insecticides. It is believed that some of these chemicals, particularly nicotine sulfate, will serve as substitutes for some of the scarcer ones. Estimated requirements and supplies of the following insecticides for 1943 are given in t'o'nst arsenic, 70,800, 70,800j cryolite> 6000, 9000; nicotine sulfate, 2350, 2400; and copper chemi- cals, 102,500, 105,000. State and county U.S.D.A. V/ar Boardsare urged to assist farmers in the selection of insecticides and to request them to use smaller amounts of the more critical materials and to substitute wherever possible. Virtually all insecticides have been placed under 17. P. B. control and most of them have been restricted to use for agricultural crops only. In case of some chemicals such as rotenone and pyrethrum, l/.P.B. controls permit their use on just certain specified crops. For example, rotenone, in accordance v;ith the \<.P.B. regula- tion, can only be used in the protection of food crops other than citrus fruits, cotton, tobacco, cranberries, eggplants, cucurbits, onions, peppers, sweet corn, or as a spray, wash or dust in the treatment of cattle for the destruc- tion of grubs. O.P.A. regulations place most insecticides under certain price •6- ceilings which seek to protect the farmer, supplier and manufacturer from possible fluotations in price due to the scarcity of supply. Arsenic trioxide, from which all arsenical* are derived, is used chiefly in the control of pests on apples,, cotton and potatoes. Cryolite is used to combat apple pests in the Northwest. Rotenone is the principal insecticidal constituent of timbo, barbasco, cube and derris root. It was formerly used in the control of many different kinds of pestsr However, its use is now restricted to certain crops, Pyrethrum is the active in- gredient of «pray», v/ashes, powders and dusts used on certain vegetable crops and on livestock. Nicotine sulfate is widely used, and this year it must help supplant the shortage of other materials, SHOULD INSECTICIDES AM) FUNGICIDES BE RATIOI^IED? In view of the situation concerning coffee, sugar, and many other com- modities, this seems to be a logical question. In a recent issue of A, I,F. News, these points are brought outi To ration a thing - to limit each con- sumer to so many oxmces a week - there must be enough so that each consumer actually can find and buy that many ounces. If insecticides and fungicides were rationed on any conceivable basis, no grower facing a real attack by insects or plant disease would get enough. And those fortunate enough to escape would not need even the amounts alloted to them. There are more than enough of agricultural insecticides and fungicides for average needs, even though not enough to ration. Insecticides and fungi- cides/most vitally needed when insects or plant diseases appear - and when these emergencies come, they are needed in quajitities large enough to control the pests. Using not enough is money thrown away, a total loss. Fire fighting is a good parallel. A city would not think of rationing fire equipment, stationing so much apparatus and so many firemen in each block. Instead, apparatus and firemen are concentrated at strategic points, ready to rush to the places where fires breeik out. Those places are largely unpredict- able - like plant pest outbreaks, ViTien the boll v/eevil is on the march, the embattled grower may use 15 pounds of calcium arsenate to the acre. Suppose this material v/ere rationed to provide 15 pounds for each of the 25,000,000 acres of cotton. That would require 375,000,000 pounds. Yet the greatest amount of calcium arsenate ever produced and consumed in a year was 70,000,000 pounds. The annual consumption may run as low as 20,000,000 pounds. The same situation applies to many other spray and dust materials. CRITICAL SITUATION REGARDING YJOOD FIBRE SHIPPING CONTAINERS The Vfar Production Board recently released information stating that in order to purchase any empty, new or used boxes, crates, cases, barrels, kegs, kits, pails, drums, tubs, baskets or hampers, either setup or knocked down, made either fully or in part from wood or corrugated or solid fibre, and used -7- as an outer container for delivflry or shipment of materials, or any shooks, cleats, staves, headings, veneer, plywood or corrugated or solid fibre cut to size for shipping containers, preference ratings are needed. There are five preference ratings, neunely, AA-1, AA2X, AA3, M4, and M5. AA-1 preference rating is for defense material; AA2X preference rating is for the Lend-Lease Program. The other ratings are to be used by individ- uals ordering boxes from their usual sources of supply. However, if any of the AAl or AA2X ratings are ahead of the others, then there is no possibility of one getting boxes for some time to come. It is suggested by officials of the Vfar. Production Board that indi- viduals desiring complete infonaation in regard to these preference ratings (Order P-140), should confer with their local V/ar Production Board. (Quoting from this Order: The list of fruits and vegetables with AA-3 rating is as followst Dried apples, dried apricots and dried peaches. Fresh fruits and vegetables as follows: apples, apricots, bananas, cherries, citrus, grapes, nectarines, peaches, pluias, pears, prunes (fresh), berries, beans (snap and lima), carrots, peas (fresh green), and tomatoes. The list with AA-4 rating includes cran- berries, quinces, and most vegetables not listed under AA-3, This Order nearly precludes the possibility of obtaining boxes through the usual channels. However, the l/Tar Production Board says that it is per- missible for an individual to cut his own logs and have them sawn into lumber. Boxes for his own use can be manufactured from this lumber without securing a preference rating, ^ ^ *= R. B. Parmenter THREE APPIE BOXES - VffiSTERN, MICHIGAN, EASTERN A General Limitation Order affecting wooden containers was filed March 1, 1943 by the V/ar Production Board. This reduces the number of wood- en boxes and crates for fruits and vegetables to 64. Three apple boxes re- main, the V/estem Box, 10^ x ll|- x 18; the Michigan Box, 11 x 12|- x 16, and the Eastern Box, 1 l/S Bushel, 11 x 15 x 17, all inches, inside measurements. No half bushel boxes are left for apples, A pear box, 8^ x ll|- x 18 and the half pear box, 5g- x 11^ x 18, are both provided for; also a pear lug, 6^ x ISg- x 20 5/8. Use of a cleat to in- crease the capacity is permitted on the pear lug but not on the other boxes. The manufacture of boxes of other sizes is forbidden. on and after March 4, 1943. Those having supplies on hand or other types of packages may manufacture same until May 31, 1943, and those receiving shooks which are al- ready in transit, bought and received prior to April 1, 1943, may assemble such packages provided the work is completed by Llay 31, 1943. Hampers, baskets and berry cups at present being manufactured are con- tinued of certain definite sizes, which includes the bushel hamper and the bushel basket. Certain special containers for use by the Government are per- mitted. APPLE BOX REqUIREivlENTS IN THE N.Y.,»N.E« AREA A survey of the apple'box requirements in the N.Y.-N.E. area indicates that 9,500,000 new boxes vail be needed. Fruit societies and state officials ,• present the following estimate: Itoine - 600,000, N.H. - 600,000, Vt. - 350,000, Llass. - 2,000,000, R.I. - 100, OCO, Conn. - 428,000, N. Y. - 5,433,500. Total - 9,511,500. Allowing a keg of nails per 1000 boxes, about 9,500 kegs of nails will be needed. The National Apple Institute has been given these figures to present to the Vj'ar Production Board, VICTORY GARDENS The Victory Garden is the very spot on which a major conflic* of the war is being decided - the battle for food, health, and security. All ir>di- cations are that this is another bftttle that is going to go the right way during the coming months. According to reports there were around 15 million Victory gardens last summer. Qpite a few of them were on farms that had never before grown a garden. As you no doubt know, the 1942 Victory Garden campaign was a success in part because it was aided by extremely favorable weather. To come up to last year's record the 1943 Victory Garden campaign calls for bigger and better gardens and more of them. Many of these gardens will have to produce all the vegetables, particularly tomatoes, leafy green vegetables and yellow vegeta- bles needed for the family's entire yearly needs. Our armed forces and our allies have already spoken for over half of our 1943 output of canned vegetables. How true is the statement of the famous general who said, "An army travels on its stomach." A soldier needs plenty of food if he is to do a good job of fighting. V7e on the home front need plenty of food, if we are going to produce food for the soldiers and if we are going to produce the munitions and machines which the soldiers need for winning battles. Yes, all of us vdth plenty of food under our belts can do a much better job. In 1942, war activities took 1Z% of our total food production. In 1943 it is estimated that these same war activitiee will take 25^^. Tv/enty-five per cent amounts to one meal in every four. Nov; that doesn't mean that we will be short of one meal out of every four. By rationing we will have enough •feo keep us from going hungry but there is very likely to be a shortage of cer- tain essential foods unless something is done. In Massachusetts something is being done. Already Governor Saltonstall has appointed a Home Garden Committee to work on this problem of food production. The job of the committee is to promote home vegetable gardens in every city, town» and community in Massachusetts. Last year we had in Massachusetts hun- dreds of Victory Gardens but this year we are going to have thousands of Victory Gardens if this committee has anything to say about it. Now that's just where you come in. The food that you produce in your back yard garden may be the very food that will fill the empty spot in our na- tional market basket. Tomatoes and beans and corn and beets and carrots and cabbage, and go on through the list - if these are produced in the home garden, they will supply the family with vegetables during the summer months and the extra vegetables produced at home can be canned for use during the vanter months. Then your family will be able to laugh at any food shortage which might develop, G. 0, Oleson [SS MILDRED HOWARD (TENSION SEPVICS )UTH COLLEGE April 24, 1943 Prepared by the Fruit Program Coramittee 3 42 .of "the Extension Service W. 11.

Olffi REASON FOR POOR SHAPED TREES An article under this heading appeared iia the April, 1936 issue of Fruit Notes, l.e repeat what was said at that time, firmly believing that a good framev.'ork is of much importance and that young trees should be induced to make good growth from the start. "It is easy to maintain a good frame- work in a tree v/hich is making strong annual growth. A vigorously grov/ing grafted tree, for example, tends to grovr a leader type of frajnsvrork v;hile a starved or stunted tree may, vihen stimulated, break out in some unexpected quarter. Even in an ordinary v;inter when other trees suffer little or none at all, there may be just enough injury to the Baldwin wood to make it less efficient in conducting \/ater and other materials to the groviing points of the previous season. As a result, water and mineral elements become shunted into other channels where the path of conduction from the roots is shorter. And after a season of good growth these sprouts continue to grow until they themselves are wide-tracked in favor of still younger grovrths." A thought for today} "Do V^hat You Can of V-Tiat You I'jiow You Ought to Do." -3- ruru^ : That 275 carloads of apples were recently packed in 35 freight cars? The explanation is that the apples were dried. They were forced under pres- sure into No. 10 tin cans. Thirty two pounds of apples, dried until they v.'eigh only 4 pounds, go into one of these cans. A total of 200,000 boxes •or 275 carloads of fresh apples (7,680,000 lbs.) were transformed into just under a million pounds of dried apples which were packed tightly into 240,000 cans. This made 40,000 cases. That a close approximation of the date at Vifhich a given variety of fruit will mature can be made at the tine of full bloom? After a three-year study, M. A» Haller of the U.S.D.A. has concluded that the number of days from full bloom to maturity is a more reliable index of maturity than pres- sure test, ground color, seed color, or starch test. The average number of days between bloom and harvest for a few varieties are as follows: Olden- burg apple, 98; llclntosh, 127; Rhode Island Greening, 155; Llontmorency cherry, 62; Bartlett pear, 121; Elberta peach, 128. That there are approximately 4000 acres of cultivated blueberries in the U. S. with a crop value of nearly Cl»000,000? The raspberry acre- age amounts to about 59,000 acres with a crop value of more than v7»000,000. Blackberries and dewberries total nearly 35,000 acres with a crop value of $3,700,000. That the total capacity for the manufacture of synthetic nitrogen in the United States after the war will be more than tv/ice as great as this country's maximum annual pre-war consumption of nitrogen for all purposes? The amount of nitrogen v;hich can be supplied to farmers from this expanded industry will greatly affect crop production after the war. The problem of utilizing this unprecedented tonnage of nitrogen is to be studied by a re- cently organized committee of which R. II. Salter, Chief of the U.S. Bureau of Plant Industry, is chairman. That soils of Massachusetts are by nature predominantly acid? Many cultivated plants or crops grov/ poorly on an acid soil v;hile certain others may fail utterly unless lime in some forra is used to correct this condition. More than 50,000 tons of liming material are used annually to increase crop yields in Massachusetts. For full details concerning this subject, see Mass. State College Leafl^jt No. 134, "Liming Soils." That crganic matter performs at least four important functions in the soil? (1) It gives the soil a good structure and improves its tilth. (2) It provides food for bacteria. (3) It keeps plant food available so the plants can use them. (4) It serves as a storehouse of nitrogen, available phos- phorus, potash and other plant foods. .4- That the State of V/ashington takes first place in the production of apples and second in pears? This state is also second in apricots and fil- berts, third in cherries, prunes and plums, fourth in grapes, and sixth in peaches. That bet\/een 2 and 2-^ million pounds of apple syrup will be produced coimiercially this year from the U. S. and Canadian apple crop, thus opening a nevj- market for apple growers? The ne-vi syrup has much the same qualities as glycerine and is being extensively used in the manufacture of tobacco. This nev; material will free millions of pounds of glycerine for use in the manufacture of explosives. That plastic, self-lubricated bearings are now in use in large, rotary fruit juice extractors? Faced v/ith a shortage of bronze bearings, one machinery manufacturer found that a nev; type of "Lucite" bearing ivas actually lubricated by contact v;ith citrus juices. The nev/ bearings are equally resistant to orange, grapefruit and lemon juices. That a record grapefruit crop of 46 million boxes is indicated for the present season compared v/ith 40 million boxes last season and 42 million boxes the previous season? The quantity of Florida grapefruit handled by commercial processors to the end of February this year is more than twice as much as was handled up to that date last year. Texas also has a record grapefruit crop, 16 million boxes, which is 14^o more than in 1942, That a thin film of water-miscible v;ax applied to apples during the packing operation is now considered as a low cost method of prolonging stor- age and market life of the fruit? This means of reducing losses from shrivel- ing is being studied at the Maryland Experiment Station, using Grimes Golden and Golden Delicious, both of which are very subject to shrivelling. That red currants nay not be as dangerous in the spread of v/hite pine blister rust as is coiiimonly supposed? Recent studies show that white pines become infected only rarely, even at short distances, from red currant bushes. The necessity of removing red currant bushes v.'ithin 900 feet of which pines has not apparently been conclusively demonstrated. That an unbelievable total of 27 million board feet of lumber may be saved by making a fev/ simple adjustments in the thickness of apple box boards? According to a committee in the Northwest, these suggested changes will do the trick; Reduce the thiclcness of the ends from 25/32 inches to 11/16 inches; sides from 3/8 to 5/l6, and tops and bottoms from l/4 to 3/16 inches. It is claimed that the slight reduction in thickness of the sides alone viould save 12 million board feet of luraber in a single year. That a gigantic machine for shredding orchard brush is now in use in the VIenatchee district in YJashington? This brush shredder, purchased by a group of 40 growers last year is capable of chewing brush at the rate of 6 acres per hour. The brush is first windrowed which enables the machine to scoop up everything in its path, leaving a trail of finely ground wood chips and splinters. -5- That only about IS^^o of the apple trees in the U.S. were of non- bearing age in 1940, compared v;ith about 24fo in 1930? Even thouch there were only about l/o as many apple trees in the United States in 1940 as in 1910, the production has not declined greatly owing in part to the gradual shift to better soils, higher yielding varieties, less caustic fungicides, and better all around orchard management. That an average ton of farm laanure contains about 10 pounds of nitrogen, 5 pounds of phosphoric acid, and 10 pounds of potash? The amount of manure produced annually per 1000 pounds of live weight is about 15 tons by cov/s, 12 tons by horses, 10 tons by sheep or fattening cattle, 18 tons by hogs, and 4.2 tons by chickens. That the guano birds of Peru consume about 5g- million tons of fish annually, while the people of Peru consur.ie only 4 thousand tons. The guano birds are considered to be araong the most important in the world because of the enormous quantities of fertilizer for which they are responsible. That ragv:eed has at least one advantage to offset its disadvantage as a spreader of hay fever? The ragweed borer has been found to be host to several parasites of the Oriental fruit moth, a serious pest of peaches. One experiment station has even recommended that ragv/eed be allovred to grow in peach orchards in order to favor the development of these parasites. That apple scab, fungus disease Enemy !Jo. 1 of apples, is known in all apple growing regions from the Atlantic to the Pacific? It is also found in British Columbia and in Southern Canada, in European countries, and in Australia, New Zealand and South Africa. The annual loss attributed to this disease in the northern part of the United States alone is estimated at v3, 000, 000 while for the entire United States the loss is approximately !1^40,000,000. That the entrance of apple scab into a leaf or fruit is dependent to a large extent upon temperature? If the temperature is 43° the process takes about 15 hours, at 48° 11 hours, 59° 7 hours, 68° 4 to 5 hours, 75° 6 hours. Higher temperatures tend to retard or prevent grovrth. Leaves must remain wet about three times as long at 43° as at 68°. That spray lime if exposed for a period of time to the air, loses its effectiveness as a corrective for arsenical burning? This is due to the fact that thfe essential ingredient, calcium oxide, is changed into the car- bonate form, calcium carbonate, by the absorption of carbon dioxide from the air. In the carbonate form, the calciura is ineffective in preventing spray injury. That 29^^ of the farm accidents in the United States have to dowLth machinery? 22^^ involve animals; lO^o, excessive heat; 9^^, falls of various kinds, 9^j, vehicular traffic, 6% lightning, and 15Jo other causes. That about 18,500 farmers in the U.S. lost their lives last year be- cause of accidents? In addition, it is estimated that 100 times as many were injured. Hazards are even greater no\/ because of new help. Greater care must therefore be exercised to avoid accidents, particularly with trac- tors and other farm equipment. -6- That the average farm garden in Michigan, amounting to l/z acre, produces enough food to rate as one of the best cash crops? On good land, properly managed and with rows spaced three feet apart, this average farm garden requires 92 hours of work. The resulting vegetables, accordingto a recent study, are worth nearly s?200. The average farm gardener plants 18 different crops. BOX CEILINGS In order to establish a price on New England apple boxes, the Office of Price Administration has issued recently Amendment No. 3 to Maximum Price Regulation No. 320, effective April 15, 1943. This estab- lishes price ceilings on apple boxes, cranberry boxes and field crates in the six New England states. The original regulation did not include New England. The amendment places a ceiling of 021.50 per hundred on 1 l/8 bu. apple crates, in the shook, and a price of v24,50 per hundred nailed up including delivery within 50 miles of the sawmill. The price on cranberry boxes is ^28. 00 per hundred in the shook, and 1)31.00 nailed up, IM7 STRAV/BERRY VARIETIES The following new strawberry varieties which are being named and introduced by the New Jersey Small Fruits Council this spring have been fruited twojears at Amherst. Our observations are as follows: Julymorn (N.J. 225). Very late, very dark red, large, objectionably furrowed, firm, very tart, good production. It is reported to be desirable for canning or freezing, but is not resistant to red stele. Crimson Glow (N.J. 311). Mid season, dark, glossy, large, good quality, but not outstanding. Not resistant to red stele. Sparkle (N.J. 312). Late, excellent quality, attractive red, firm, good production. Promising at Ajnherst. Reported to be very resistant to red stele. A. P. French PRODUCTION OF FRUITS IN NORTH AFRICA 17e have recently obtained from Fred A. Ilotz, formerly foreign market- ing specialist of the U.S.D.A., some figures concerning the production of fruits in a much publicized corner of the world. North Africa. The 1938 figures for Morocco are as follows: oranges, 1,547,000 trees; almonds, 4,604,000 trees; figs, 7,366,000; dates, 1,118,000; pomegranates, 585,000; and chestnuts, 204,000. The average annual production of various fruits in Algeria between 1934 and 1938 were as follows: oranges, 1,522,000 boxes; mandarin oranges, 1,253,000 boxes; lemons, 102,000 boxes; figs (fresh consumption) 25,500 tons, (dried) 19,200 tons; dates, 114 tons; olive oil, 15,400 tons. -7- The 1930 statistics show 29,800 acres in orchards in Algeria with a total of 1,400,000 trees. Amonc the deciduous fruits v/ere apples and pears, 4,400 acres; plums, 5,900 acres; peaches, 5,200 acres; cherries, 2,300 acres; apricots, 2,000 acres; almonds, 4,600 acres; medlars, 959 acres. To v/hat extent these fruit plantings are being taken care of at the present time is a question. Under Axis domination the production un- doubtedly dropped. It will be interesting to Icnow to what extent the events of last November may have changed the agricultural picture in North Africa. RAIN - HAY - MICE - GIRDLED TREES That's about the order of events which has resulted in some of the worst cases of mouse injury we've seen in years. In four orchards which have come to our attention growers are faced with a real job of bridge graft- ing. The reasons for so much mouse injury are not difficult to determine. A heavy hay crop in 1942 plus many unharvested drops set the stage for an unusually heavy mouse population. Ideal "cover" provided not only protection against natural enemies but a good food supply in the form of tender grass. And so liicrotus raised large families and many of them. With well established runs around the bases of apple trees the next step was to supplement the grass diet with generous samples of succulent inner bark. Another factor which worked to the advantage of the mice was this. At the time when mouse bait would normally have been distributed help was scarce and difficult to get. Ilany growers took a chance on mouse injury, — and lost. There v/ill probably be a renewed interest in the use of zinc phos- phide bait next fall, thanks to a combination of circurastances v/hich favored the furry Enemy No. 1 of tiie orchard underworld. HERE'S AIT IDEA At apple harvest time next fall apple growers v;ho are fortunate enough to have a crop will undoubtedly be scouring the neighborhood for "scarcer than hens' teeth" apple pickers. Good apple boxes will be not only expensive but difficult to get. Available storage space must be used to good advantage. Considering all these things, why not make sure that at least 90^ of the apples you grow this season are worthy of your efforts at harvest time, your packages and your storage? Grow only good stuff. Solve the low grade fruit problem by not growing low grade fruit. Even in normal times apples below U.S. No. 1 grade are likely to be more of a liability than an asset. In wartime they become increasingly so. ITalter R. Clarke of Ulster County, New York, v;riting in the Rural New Yorker, has this to say about apple grades and prices. "I believe it is true that the retail prices of apples are as high as we can expect for the nop notchers, Fancy and good No. I's, but our trouble comes in the growing, handling and selling of that 30 or 40 per cent betv/een cull and these top notchers. Carefully worked out figures show a loss of almost 20 cents per box on that percentage of our crops. This loss, taken from the gain made on the good GO per cent, does not leave enough profit for the grower and his investment to keep him happy, grov/ing apples." ■ 8- FRUIT PEST CONTROL IN GREAT BRITAIN The ingenuity of the people of Great Britain is v;ell illustrated in a group which has come to be knovm as Britain's "Golden Angels." The girls of Great Britain are doing work of every description during these wartime days that have taken men from their normal posts of work. Included are the multitude of tasks that must be done in the orchard. The girls are being trained thoroughly in the use of all apparatus and in the technical principles of spraying. Recently, a corps of spraying girls was formed in an endeavor to free orchards and fruit plantations from pests. One of the sprays generally used has the effect of turning the skin a bright golden yelloT/. As a result, the spraying girls have become knovm throughout Britain as the "Golden Angels." (Let's hope that the material they are using is not liquid lime sulfur.) J. H. Putnam, former county agent in Franklin County, says, "Right now there is only one thing we should all be thinking of; that is what we can do to help win this war. No sacrifice is too great - no surrender of ordinary rights too momentous - no privation too hard to bear. Wiy should mq gruinble about rationing of sugar, and oil, and gas, parity - subsidy, labor troubles, and heavy taxes, when our boys are offering their all - even their lives?" THE PLACE OF SHALL FRUITS IN THE IIOIE GARDEN PROGRAI.I Home owners throughout Massachusetts are v/ondering whether or not fruits of various kinds should be included in the Victory Garden. To ansv/er questions along this line, the Department of pomology lias prepared the fol- lowing statement covering the various small fruits. Vfhere space is limited and the garden is a wartiiiifi measure only, small fruits should not be grown in preference to vegetables. However, they make a welcome and valuable addition to the diet, V.'here space is available and the garden is to be continued for tv^o or more years, some of the small fruits may well be included. No small fruit plant should be allowed to fruit the first season except "everbearing" strawberries, which are not generally satisfactory. Small fruits should not be planted in the middle of the vegetable garden, StraviTberries bring the quickest returns. Plants set this spring will bear a crop next spring. Fifty plants should supply a family of four. For best results new plants should be set each spring. Grapes usually bear the third year and continue for many years. Quicker returns maybe had from renovation of old vines, since they are capable of producing a crop the next fall. Red Raspberries bear a small crop the second year and should come into full bearing the third year. Boysenberries are not recommended for general planting in this state but ;iay suc^ceed'on lighter soils. Blue- berries come into full pi'oduction so slov/ly that they are not well adapted to the wartime garden. One definition of Entomology - "Gettin' right in among the bugs and watohin' 'em work."

From the apple grower's standpoint, the season is characterized by late bud developipent, early scab development, and day after day of wrong kind of weather for spraying. Below normal temperatures in April delayed fruit buds to an almost unprecedented degree. Bud development has been lagging approximately two weeks behind 194E, This spring vihen Mcintosh buds had reached the Delayed Dormant stage we were reminded that on the same date in 1942 the buds were in the Pink stage. Fruit buds, being very sensi- tive to temperature, refuse to open up until the weather is reasonably warm, V/hile the apple buds were biding their time, the apple scab in the old leaves on the ground was steadily developing. At the Pre-Pink stage of bud development there were about as many mature spores in the old leaves as we normally find at blossoming time, Vfe may safely say that a larger per- centage of scab spores were either mature or already released by the time the blossoms were ready to open than has been the case in all the years we've been fighting scab in Massachusetts, Careful studies of old leaves from various sections of the state, made by 0, C. Boyd on May 19, revealed the interesting fact that a mere 10 to 20^o of the scab spores still remained in the old leaves. This represents an unusual spore discharge - not from the standpoint of the calendar, but of bud development. Spray Message for Massachusetts Fpuit Growers (No. 8), issued May 19, carried this timely suggestion: "If apple trees came into bloom before the Pink spray could be completed, it is advisable to finish that spray with sul- fur alone, Apple varieties subject to scab and cedar rust need protection throughout the blossom period, particularly if v/et v;eather threatens. Either a sulfur dust or a wettable sulfur spray may be used, but lead arsenate should be omitted. The protection from the Pink spray can be expected to last only five or six days at most, Vifhere apple scab infection occurred on May 10 to 12, the new scab spots should begin to show up around May 24," Apple leaves were hot held back by cool weather to the same extent as apple buds. As a result, there is more leaf area in evidence on Mcintosh spurs at blossoming time than in a normal season, Baldwin trees, on the other hand, always show a considerable leaf area at blossoming time. This year there is much less difference in the leaf area on Mcintosh and Baldwin spurs. Following is a siommRry of the scab situation in Amherst, prepared by 0.

(June 3-4) 'J That only about 20,000 of the 625,000 known species of insects in the world, damage crops and other property, or spread disease? Of the 80,000 U. S. species, only 600, or less than 1 in 100, are considered destructive. That the ovenvintering spores of Black Rot of Grapes are suffi- ciently nature to cause infection by the time the new shoots are 2 to 4 inches long? Fruit infection vrtiich occurs several weeks later is the re- sult of summer spores which come from the early infection on the new growth. That every fruit plant of a given variety in existence, whether Howard 17 strawberry or Mcintosh apple, is a direct vegetative descendant of the original seedling? One Baldwin tree in Massachusetts is said to be of the third generation. In oth.^r v/ords, it vras grafted from a tree which was grafted from the original Baldwin. The latter is listed as a casualty in the hurricane of 1815. That the waste in paring, coring and trimming apples for commercial canning of sauce amounts to more than twice as much in the 2'^" size as in the 3" and up? The losses per 100 lbs. amount to about 43 and 18 lbs. re- spectively. Numbers of apples per 100 lbs. are about 665 and 268. Losses in the 2-|-" and 2 3/4" sizes amount to 30 x 23 lbs. respectively. That more than 9,000,000 tons of commercial fertilizers were used in the U. S. in 1941? Of all the states, North Carolina used the largest amount - more than 1,000,000 tons. Of the total tonnage used in the country, federal agencies (AAA h Ilk) distributed about 800,000 tons. That the total cash income of American farmers in 1941 amounted to $ll,830rpOOO,000? This is the largest income received since 1920 v^hen it totalled $12,608,000,000. The increase in 1941 over 1940 was $2,700,000,000.

Drum says, "Forest fires destroy a priceless source of raw material and also serve the enemy by endangering vital installations," ■ 4- ■APPLE BLOSSOMS (A Borrowed Editorial) Seeing an apple tree in bloom makes it easier to understand Johnny Appleseed's passion for planting orchards in the wilderness. A well-ordered orchard is a magnificent sight at this time of year, but even more breath taking must have been the beauty of the trees the old wanderer planted all up and down the Ohio Country when most of it was still Indian Land. Primi- tive Christian that he was, old Johnny must have exclaimisd many times at the beauty of God's works and the bounty of His benevolent hand. Those who walk the hills today get the same feeling when they come upon an orchard abandoned to meadow grass and gone wild. The old trees, gnarled with struggle and untrimmed for years, lift their blossom-laden branches as offering to the sun, and all around them stand the young wild- lings, sprung from seed and surviving only by their ovm strength and hardi- hood. The air is sweet with their fragrance and loud with their company of bees. Every stage of beauty lines the branches, from the flush of the bud to the ivide-petaled whiteness of full bloom. The abandoned apple tree and its seedlings belong with the wild rose and tho blackberry tangle; with the roso in particular, vihich the botanist meticulously points out is its cousin once or twice removed. And it is the particular possession of May, when Spring is no longer in doubt and Summer has not yet really turned on the heat. It belongs v/ith warm rain and the first buttercups and scarlet tanagers telling the morning what a lovely thing it is to be alive. Johnny Appleseed knew what he was about, PRICE CEILINGS FOR APPLES A committee representing the apple growers of the northeastern states, including John Chandler and John Lyman, has prepared the following statement for the OPA after considering all angles of the apple industry: The Northeast has become the arsenal of the United States. In- dustry has expanded beyond the most optimistic estimates. Agriculture in the Northeast is not extensive in the light of the over-all picture, but agriculture is definitely rising to the emergency with greater than anti- cipated production under handicaps of shortages of labor, machinery, materials, etc. The apple growers of the Northeast produced and harvested one of the largest crops on record in 1942 and marketed it in a vory order- ly manner at fair prices to the consumer. Indications in the orchards this spring point to a crop of apples which v;ill probably be smaller than that in 1942, but may not bo smaller than an average crop for the five years prior to 1942. Thus, we should not expect a real shortage of apples - neither should be expect a run-away market. The apple growers of the Northeast feel that we have a definite part to play in the production of food for the successful conduct of tho war, Vfo are anxious to grow, harvest and market a crop of the best apples -5- possible and, given the propor market support, it v.'ill be done. Any novo to establish ceiling prices vj-hich will weaken this support will have a definite destructive effect on the production of apples. Following a meeting of the National Apple Planning Committee and a meeting of the apple grov/ers of the Northeast, at which price ceilings v;ere discussed, it was concluded that ceiling prices on apples v;ould be impractical and have a tendency to discourage the greatest production of apples. Apples are highly perishable, subject to t he vagaries of weather, deterioration and many other factors beyond the control of growers. Arbi- trary controls introduced into such situations do not provide for suffi- ciently flexible adjustments for these rapidly changing conditions. However, if our Government is committed to ceiling prices on all commodities, to control inflation and protect the consumer from run-away prices, the apple grov/ers stand ready to cooperate v;ith it. To make the plan simple and easily understood by the consumer and easily enforced, v/e suggest that should there be such a price ceiling, it be a price ceiling to the consumer v/ith no other control along the line. This price should be sot high enough to encourage the largest production of the best grade of the most desirable variety grown in the most remote areas of production. We feel that should such a ceiling be established with an average crop of apples well distributed in all producing areas, as was predicted by the National Apple Planning Committee, it would provide a chance for the law of supply and demand to work as nearly normally as possible. IN CONCLUSION: 1. Vie do not believe arbitrary price controls are for the best interests of the producers or the consumers in that they discourage production and hamper distribution. 2. If a ceiling is to be applied, it should be applied only on the retail price, 3. The Apple Industry is highly competitive, both vrithin itself and with othJer fruits. If a price ceiling is applied, we suggest it be applied at a level that will inter- fere as little as possible xrith the normal laxt of supply and demand. FARI/I LABOR PROBLEII BEING SOLVED Vfith emergency farm labor assistants appointed for all counties and with state and federal agencies coordinating their efforts, Massachu- setts is rapidly developing a program which should effectively handle the farm labor problem. The program developed by tho Massachusetts Farm Labor Committee is right in line with the federal farm labor plan which went into offect ■ 6- May 1. Hence the program already started will continue under the super- vision of the Massachusetts State College Extension Service at Amherst. In close cooperation will be the Massachusetts Farm Labor Committee ap- pointed several months ago by Governor Saltonstall, the high schools, the U.S. Employment Service, and other interested groups. In dealing with the farm labor problem first attention should be given to the full utilization of all labor resources within the comraunity. ViThere there is not enough labor available locally the farm labor assistants will attempt to recruit workers from nearby communities. The need of year- round workers on farms presents a much more difficult problem. There is no supply pf year-round workers. Consequently close cooperation with local selectiTO^D%iards is needed to keep present necessary year-round workers on productive or essential farms. The county agricultural agents have full responsibility for the recruitment and placement of farm workers in their respective counties. They will be assisted by these nev^ly appointed emergency farm labor assist- ants. These men will do everything in their pov;er, but it will be necessary for any farmer who has a farm labor problem to take that problem to the county agricultural agent's office. For Suffolk County the emergency farm labor assistant is John B. Casey, head master of the Jamaica Plain High School. In close cooperation with the farm labor program will be the woman's land army and the 4-H farm labor project, — Roy E.

Vforcester 3-5477 NEW I-ffiTHOD OF PPi:SERVING FRUITS The British made a request when we began to ship them fruits under the Lend-Lease program. Vfould v/e please just preserve them in sulphur di- oxide solution, and ship them over in wooden casks? That was a big surprise for our food men. Wouldn't the British prefer fruits canned in bright tin containers? No, the British really wouldn't. Ylell, the British were eating the fruit, so let them have it the way they wanted it. And the sulphur di- oxide method is saving tin. So the big American canners turned out the British fruit orders the ■ 8- way they wanted it: 250,000 barrels have gone to them in this sulphur dioxide solution during the past three years. The sulphur dioxide method is simple. Take strawberries, for example. The berries roll straight from the field to the freight loading platform, alongside the railroad tracks. They're washed, hulled, and dumped into wooden barrels with a 2jb sulphur dioxide solution. The barrel is sealed, put on the freight car, and it's on the way to England. The whole thing takes half an hour. Millions of pounds of these sulphited strawberries are being shipped to England this season. The preservation of peaches takes a little longer because they have to be peeled and pitted. Last year v;e shipped, in this manner, citrus pulp, peaches, strawberries, raspberries, and dev/berries. This year we'll probably add cherries. Fruits preserved in sulphur dioxide are used for preserves, jams, ice cream, and pies. These sulphited foods, such as strawberries, have to go through a special step when they're taken out of the wooden casks to start on their way to jams and pies. They must be boiled vigorously for 45 minutes. That drives off the sulphur dioxide in the steam. And with it, the bitter sul- phur taste. Oddly, the sulphur dioxide solution takes most of the color out of fruits. But when they boil for 45 minutes, the color comes back. And that's important, because who wants to eat pale ycllov/ strav/berry jam? WINTER KILLING OF RASPBERRIES The following table givjs an estimate of the amount of winter kill- ing in a planting of young raspberries set at the State College in the spring of 1942. To get a better measure of the true cold resistance of the varieties, canes which were on the ground and therefore protected by snow v/ere ignored in making the estimate. On all varieties it was very noticeable that big, vigorous, branching canes v/ere injured vrorse than smaller, less vigorous canes.

S. Bailey -9- CONTROLLED ATMOSPHERE STORAGE The controlled atmosphere or so-called "gas" storage room at H.S.C. was opened April 30 just a little over seven months after it v/as sealed up on September 25, 1942. The Mcintosh apples from this room vfhich vi&s held at 40° F. were more firm, crisp and juicy and definitely higher in eating quality than similar apples held at 32° in a common cold storage room. This was due to the fact that in the controlled atmosphere storage vmere the oxygen supply was drastically reduced and the carbon dioxide was main- tained at a relatively high level, the apples "lived" at a comparatively slow rate even at the 40° F. temperature. As previously described, apples use up oxygen and give off carbon dioxide. In the tight room, this process contined until the oxygen level was dovm to 2% or at times slij^htly lower. The carbon dioxide increased, of course, but was not allovred to get above 10^ because of possible toxic effects. This was accomplished by periodically removing this gas by passing the atmosphere of the room through a special "washer." The contents of oxygen and carbon dioxide were measured every other day or so to determine when "washing" or ventilation were required to maintain the artificial atmosphere. One trouble not encountered heretofore was a soft scald type of injury which may have been due to an insufficiency of oxygen during the in- tervals v/'hen the oxygen level v/as below 2^^. This experience indicates the special care that must be exercised in operating a storage of this kind. However, the peculiar difficulties encountered with this type of storage are far from insurmountable as proven by the successful operation of sev- eral controlled atraosphore storages in Hew York State. It is reported that Mcintosh out of these storages this spring brought from one to tv-o dollars a bushel above the wholesale market price of regular cold storage Mcintosh. Perhaps, with the return of peacetime conditions, controlled atmosphere storage may find a place in Massachusetts, at least on a limited scale. — Lawrence Southwick — 0. C. Roberts THE FUNGICIDE AHD INSECTICIDE SITUATION The following information is based upon recent reports chiefly from the Agricultural Insecticide and Fungicide Association, the Agricultural Chem- icals Section of the Office of Price Administration, and the Chemicals Division of the Food Production Administration. Lead Arsenate: The production for 1943, which will be lO^o less than in 1942 but 10^T"g."^ter than in 1941, is to be cOmpletedby June 30. A re- strictive order precludes its use on shade trees, ornamentals, lawns and golf greens at least ui-^til after sufficient supplies are assured to protect essen- tial crops. The supply available for food and fiber crops is expected to equal that used for the corresponding crops in 1942. Calcium Arsenate; The present schedule calls for a substantial in- crease over the 'supply m 1942. Sixty per cent of the total production vail be completed by June 30 compared with 40 per cent at that date last year. ■ 10- Copper Fungicides! Until recently, the 1943 schedule indicated 80,000,000 lbs, of copper sulfate for agriculture, the same anount allocated for that purpose in 1942. The Office of Food Production Administration re- cently announced that this figure would likely be increased to 100,000,000 pounds, in view of the increased acreage of potatoes and vegetables through- out the country. That office estimates that 75,000,000 pounds will bo needed to protect potatoes, tomatoes and fruits. It also cautions that " although the supply of copper compounds will be the largest in history, every effort must be made to conserve supplies." Rotencne; The nation's supply is drastically limited and strictly allocated, "he country used in 1941 about 8,500^000 pounds of roots, and in 1942 about 6,500,000 pounds. The Food Production Administration estimates that "this year close to 3,000,000 pounds will be available to meet the requirements of the crops and uses as set forth in amended Conservation Order K-'.".o3." This limitation ordor restricts the use of rotenone on crops to per.f fcr weevil and aphids; to beans for the Mexican bean beetle; to sweot corn fcr the European corn borirT and to cole crops other than cabbage X^EKirV iSj"to broccoli, cauliflower, brussols 3p'rc'ut's~kaTe, etc.) for cater- pillars and aphids J Rotenone dusts manufactured in 1943 may contain not more than 0^5 per cent rotenone, and they may not contain any pyretiirum, Derris and Cube powders may not contain more than 4 per cent rotenone. Re- garding the dilutions for Derris and Cube preparations in spray form, the amended Conservation Order 1.1-133 "permits the use of 4 per cent rotenone spray powder in accordance v:ith common practice," Pyrethrum; Although supplies are substantial, their use in agricul- ture is dra3tic"ally limited because of military needs. A limitation order novj- in preparation, it is reported, permits the use of pyrethrum on all Cole crops (cabbage family); on vegetables in the homo, farm and community gardens; on beet-seed crops; on corn, beans and potatoes; and on grapes and cranberries, Cryolite; Supplies for 1943 are much greater than ever before — 15,000,000 pouiids as coiapared with 6,000,000 pounds in 1942, Cryolite nay be used in place of arsenicals on shade trees and« ornamental s , and as a possible substitute for lead arsenate on apples and pears. It is also being recoinraended for the control of chewing insscts on various vegetable crops. Nicotine Sulfate; Provision by U.S,D.A. for the production in 1941-43 of about Is800j000 pounds through a tobacco diversion program, in addition to the quantity ordinarily obtained f rom tobacco wastes, insures an ample supply for insecticidal purposes, A production of about 3,000,000 pounds is estimated for 1943. Calcium Caseinate; Domestic production is now low because of milk problems. Tne' situation,"^nowever, is expected to improve with the advance of the season. These are Adequate; Cyanides, Fish Oils, Hormone Sprays, Spray Oils, Paradichlorobonzene, Borax, Spreaders and Stickers, Zinc Oxide, and Zinc Sulfate. —0. C, Boyd and A. I.

The idea of women working on farms is not new. Throughout history they have done many tasks. And so it is today - women are already working, and still more - are willing to work on farms in Massachusetts. Members of the Yifomen's Land Army must be at least 18 years of age and must secure from their local doctor a certificate stating they are in good physical condition for hard farm work. Women may enroll as either full- time or part-time farm workers but must agree to work at least one month. It is not necessary to have had farm experience. In fact, many farmers pre- fer training their own help for specific farm \vork. To hold the patriotic place with WAACS, TfAVES, Marines, and SPARS, members of the Women's Land Army are eligible to wear the uniform designed for farm labor. It consists of a dark blue coverall, a light blue shirt, a hat of two shades of blue, and a dark blue jacket. On a fruit farm there are many jobs that women have done and can do, such as: help with the spraying and pruning, picking, grading and packing of fruit, and driving the truck to market. In some cases, it might be more efficient, if the members of the Yifoman's Land Army took over some of the responsibilities in the home, and so relieve the farm homemaker to work out- side on the farm. Arrangements may be made by one or two neighboring farmers who might have need for part-time employment of a woman to help on their farms. To- gether they could keep her employed full-time. In other cases, a group of 6 or 8 women might be housed in the village center, and several farmers ar- range for the transportation of workers to their farms nearby. Your County Agricultural Agent or Emergency Farm Labor Assistant located at the County Extension Office are able to help you in locating members of the Women's Land Army to work on your farm. —Beatrice E. Billings CURCULIO ON NON-BEARING TREES Having jarred five curculio beetles from a small peach tree a few days ago at the Derby fann in Leominster, vfe were interested in knowing if this insect is commonly found on trees without a crop of fruit. So we put the question up to TiT. D. Whitcomb of Waltham. He answered as follows: "The collection of curculio beetles on peach trees withovit fruit is not unusual. In the early part of the active season there is considerable migration during which the beetles apparently are searching for fruit for oviposition. Curculio beetles d efinitely feed on blossom petals but I have no record of feeding on foliage. It is quite possible, however, that they feed slightly on the leaf petiole and possibly on tender shoots." -3- ^)>?>^"^'^^^^''^ ^d&i.

Hundreds of people, inexperienced in farm work are going on farms to assist in the planting, cultivating and harvesting of crops and the care of livestock. In general, these people vj-ill be willing but are completely inexpf3rienced. The results obtained from this inexperienced help will depend a great deal upon the "breaking-in program"which farmers employ. Greeting the New Farm Worker - There's a Vfrong Yfay and a Right Yfay A schoolboy has decided to help with farm work, and has been assigned or directed to go to a certain farm. He has just arrived by bus and finds Fanner "A" in the barn wherethe following conversation takes place; Farmer "A" - "Hello, Bub. V/hat do you want?" Boy - "I was sent here by Mr. Green, the County Agent, to help you •with your farm work." Farmer "A" - "You look pretty puny to ne to be much good on this farm. How old are you, anyvv-ay?" Boy - "I an sixteen, sir. Vfiiile I'm not as tall as some of the boys I think you will find I can take it. I have delivered papers for the past two years and played on the scrub foot- ball team." Farmer "A" - "Vfell, you'll find farming isn't football. It's hard v;ork from before daylight until after dark. ITe farraers have a hard life and you'll soon find that out. Did you ever vrork on a farm?" Boy - "I have never worked on a farm before, sir, but I am certain I can learn if you v/ill show me," Farmer "A" - "Vlell, take that fork and go down there and clean up that cow stable. Let's get going." Such an approach makes a boy or any other eager and enthusiastic but inexperienced worker feel that the farm job is the hardest, most difficult to learn, and will dampen enthusiasm, shatter morale and cause him to v^ork below top effectiveness. Let's see how the young farm worker might better be handled. (Boy gets off from a bus and finds Farmer Bill Smith in the barn.) Mr. Smith - "Good morning. Aren't you John Brown, the young man Mr. Green told us would come out to help v/ith the farm v/ork this summer?" John - "Yes, sir, I am John." --5- Mr. S. - "Well, I »m Vfillieon Smith. They call me 'Bill.' Mind if I call you 'Jack?'" J. - "No, sir, that's wliat all my friends call ne." Mr. S. - "Fine, I'm glad you are here to help us. Jack. Let' sit down here and get acquainted and I'll tell you something about our place. Have you ever worked on a fa:in. Jack?" J. - "No, sir, but I have worked summers delivering groceries and I carried a paper route. Then of course, I v>rorked around our yard but it isn't farm work." Mr. S. - "i.Tell, don't worry about that. Jack, I Icnow you are going to like farm v;ork and I will shov/ you all about the jobs you will have to do. Farming is mighty fine work. It is mostly outdoors where we have plenty of fresh air and sunshine. By the vra^', that's why lots of people play golf; to get plenty of fresh air, sunshin." and exercise. Vfell, we have all three right here on this farr.. You are vrorking with grovang plants and animals, and ycu learn a lot that wrill be of real interest and help you as long as j''Ou live. By the v/ay, my wife wants to meet you. She told me to bring you up to the house when you cane. Boy, is sh*; a good cook! She puts out lots of good food and plenty of it." They go into the house where ivir. Smith introduces Jack to his wife who carries on a pleasant conver- sation with him, telling him she is glad that lie has come to help them, Mr. S. - "lYell, Jack, let's go out to the barn now. Just as you were coming I was about ready to start cleaning out the coy; stable. That isn't the most interesting work we do around here but it is a job that has to be done every day. You see, on this farm we produce milk, and babies in the cities drink this milk. The milk has to be clean and sv/eet and wholesome, V/e can't produce good cleann milk in a dirty cov; stable so we try to keep our stable and our cows nice and clean all the time. Do you vj-ant to take that fork over there and we v/ill clean this up and when we get done we v/ill do something else," This conversation continues vath the main object of getting acquainted. Jack is shovm his room. The importance of dressing safely is explained to him so no loose tie or long unbutton^jd sleeve or any part of his clothing would be ^ likely to cause him to trip or be caught in a machine. The first dayy on any new job is the most important for developing atti- tude and morale. The new worker should be made to feel that his contribution is important, that he is doing necessary v;ork, that he will not be expected to know all the answers but he will be carefully shovm how to do each job. If he is not accustomed to rath.^r vigorous work, he should be told not to go too fast or hard unless he is able to do so without unusual tiring or fatigue.

MOBer T'^/^^AJ That Mcintosh apples can become infected by scab during July only if they remain wet continuously for 35 to 40 hours? During August a v;etting pero/od of 40 to 60 hours is required for scab infection while 3 to 5 days of continu- ous v/'etting are necessary in September, according to 0. C. Boyd. At the same time young leaves may become infected in 6 to 8 hours while older leaves require 15 to 20 hours. That per capita consvunption of food in peace time is somewhat more than 3 pounds a day while soldiers require &|- pounds? In a theater of war, a fight- ing man eats tvro-thirds of his food out of tin cans. That 83.8 million of the 127.5 million bushels of apples grovm in the United States in 1942 were sold commercially as fresh apples? Other channels of distribution accounting for the balance (expressed in millions of bushels) are: Food distribution administration - purchases, fresh, 2.5; Cold packed, .5; Canned, 11.8; Dried, 7.9; Other llfg., 9.; Farm household, 5.; Unharvested, 7. That Barnstable County, Massachusetts ranks 52nd among the counties of the United Stat§s in strawberry acreage and 17th in strawberry production? This indicates that strawberry growers in the Falmouth area have a per acre yield of approximately tRree times the average yield in the United States. That several fruits, including cherries, plums, grapes, and currants, will develop normal color in dense shade? The red coloring material in apples, however, requires at least partial exposure to sunlight for its development. That a valuable oil is nov; being extracted from the seeds of grapes? Grape seeds contain 10 to 17 per cent oil on a moisture-free basis. The 900,000 tons of grapes normally used in making wine in California will yield more than 3,000 tons of oil. The oil is semi-drying and may be used in paint. That Yakima County, Yfashington is the loading apple producing county in tho'. U. S.? The crop last season fron about one and a quarter million trees amounted to more than 10,500,000 bushels. That ;a silvery condition in apple leaves, commonly knovm as Silver Loaf, is caused by a wood rotting fungus? Tho silvering is due apparently to a toxin or poison produced in tho trunk or branch and carried upward into the leaves.

It is difficult to imagine more nearly ideal conditions for apple root development than those existing just beneath a decaying mulch. Moisture supply, aeration, mineral elements (includ- ing nitrogen in nitrate form), and the absence of competition from grass, com- bine to favor growth and maintenance of the apple roots. This condition is well illustrated in several Nashoba orchards where a mulch accumulated over a long period of years is paying good dividends. It takes about three years before the nutrient materials stored up in dry hay are again made available for the tree. Decay is hastened by nitrate applications. Ben Davis affects adjacent Mcintosh. A striking example of cross pol- lination was recently observe'dT "at~a twilight meeting at Apple d'or Farm where a block of Mcintosh trees adjoins a block of Den Davis. V/here the two varieties are adjacent, the set of Mclritosh is exceedingly heavy, much more so than where the Mcintosh trees are next to Baldwins. The old Ben Davis may not be much of an apple to eat out of hand, but it ranks i.'ell with Delicious, Cortland, Astrachaa and others as a pollenizer. Fighting scab successfully in a difficult season. 17hen someone asks the question, "Doesn't everyone have a lot of scab in Mcintosh trees this year?" we can truthfully say that scab is almost completely under control in a number of the larger commercial orchards. One such orchard has received no lime sul- fur and needs none. The sprayer hus a capacity of 30-gallons per minute and maintains a pressure of 600 pounds with two 8-no2zle "brooms" in operation. T/Yettable sulfur has been supplemented by sulfur dust. The foliage looks un- usually well. Of course, not all Mcintosh growers can justify so large a sprayer. Neither can thoy afford both a sprayer and v. duster. Lacking these highly desirable pieces of equipment, a grower must of necessity take more time in spraying each tree. Faulty coverage is probably responsible for at least nine-tenths of our scabby foliage and fruit. A -V/ould-be strawberry grower. An individual vo-iting to the State Col- lege for information on strawberries said, "Last year I placed a handful of fer- tolizer in each hole where I set my strawberry plants, and the plants failed completely. This year I'm going to try lime," (An example of "spoon feeding" at its \vorst, - all too common among amateurs. It illustrates the difference between building up soil fertility in advance, and handing out generous gobs of this and that for immediate consumption.) Biennial Mcintosh. One Sterling Mcintosh orchard has alternated for the past four or five years botareon very heavy and very light crops. Terminal growth is loss than normal. The trees look relatively thin, and the cov-^r crop id lacking in vigor. All signs point to a nitrogen shortage. The soil is funda- mentally good but needs a thorough overhauling. If, through soil improvement, a hay crop of tv/o tons or more per acre is produced, t]ie trees should then make the kind of growth which accompanies annual bearing. Young apple trees shov/ brovm leaves. In one end of a South Amherst orchard of 2-year-old apple trees, the leaves show severe brovming. It isn't spray injury because they haven't been sprayed, and it isn't at all typical of ■6- nagnesiun deficiency. The soil is strongly acid and lacking in organic matter. Leaf analyses show very littlo potash. An old orchard was removed before the present trees were set. The young trees will undoubtedly respond to a program of soil improvement including an application of dolomitic limestone and a com- plete fertilizer. Other possibilities are stable manure and heavy mulching. Or as one individual remarked, "Jack up the trees and put some soil under them." Strawberry crown girdlers invade a house. At a recent twilight meet- ing a grower referred to a particular "beetle which he had found in considerable numbers in his house. He had no difficulty in capturing half a dozen which he mailpd to the State College for identification. They proved to be the Straw- berry Crown Girdler, which has a habit of seeking shelter in houses. A good idea, except - At another meeting a grower said that he had seen many curculio beetles feeding on dock leaves in his orchard and wondered if this pest might be poisoned there instead of in the trees. There seems to be only one thing wrong v;ith the idea. The insect in question is definitely not cur- culio. Apple maggot and cold storage, V^e hesitate to waste the time of readers of Fruit Notes with this one, but it provoked some discussion at a twilight meet- ing. It was offored by the ovmer of an orchard whose standards in pest control may be judged by the fact that his first spray for scab was applied after bloom. He claims to prevent apple maggot dtoaage in vdnter apples by placing them prompt- ly in cold storage. The truth of the matter is that most of the maggots fail to survive very long anyvmy in a hard apple and even though they are destroyed within a few days or a month at most by cold storage temperatures the apple still bears the telltale tunnels, and from a grading standpoint is "railroady" or maggot infested. The storage idea is not nev;. In fact, it has been care- fully investigated to determine the effect of sold storage on this unwelcome summer visitor. (\7e shall continue to recommend poisoning the fly instead of freezing the maggot.) PRODUCTION IN A 45- YEAR-OLD APPLE ORCHARD A row of eleven 45-year-old Mcintosh apple trees in a State College orchard has been cut down, , not because the trees were no longer producing profit- able crops but because they were expensive to maintain, the fruit was somev/hat inferior in color ond the land was needed for a new planting more suitable for modern research work. The crop in 1942 was the second largest in the life of the orchard. Records of the yield of these Mcintosh trees from 1920 to 1942 inclusive, have been kept. The average annual yield of the 11 trees from the 22nd to the 45th year v/as 25.4 bushels per tree or 686 bushels per acre of 27 trees. The prize tree produced 88 bushels in 1939 and averaged 38 bushels per year or 1064 bushels per acre for the 23 years j the lowest yield from a permanent treo was 23 bushels, or 621 bushels per aero. Tv/o of the 11 trees were replaced dur- -7- ing the 43 years and one weakened and died shortly before the row was removed. Omitting these three trees the average annual yield was 30 bushels per tree, or 810 bushels per acre. Yields of four additional varieties for a period of 14 years, 1923- 1936 inclusive, are available. The average annual yields of all five varieties for this period were R. I. Greening, 16 bushels; YIealthy, 13 bushels; Ben Davis, 15 bushels; Baldwin, 10 bushels; and Mcintosh, 22 bushels. This shows one reason why Mcintosh is preferred by our growers; it yields more, largely be- cause it is an annual bearer. Wealthy and Ben Davis could well be planted more than 27 trees per acre so they should be regarded as better producers than the above figures indicate, ^ y. o^aw UNSCRAMBLING VARIETY PUZZLES IH TIIE NURSERY The 23rd annual examination of nurseries for trueness-to-name began on July 12, and it will require about a month for three men to complete the vrork. It is some job to I'^arn and remember the varietal characteristics of the many varieties of apples, pears, plums, cherries, and peaches that will be examined. We propagate many varieties in our own nursery where they can be studied at various stages of development. There are now in our nursery varieties of var- . ious tree fruits as follows: apples, 61; pears, 47; plums, 59; cherries, 36; peaches, 53, ornamental crab apples, 31. Total 287 varieties. They include many varieties that are new or little known and which may appear in nurseries either as new introductions or substituted for other varieties. The numbers given above do not include "strains" or bud sports of apple varieties such as Starking, Red Spy, and about 20 possible sports of Mcintosh. Many varieties are represented by both one-year and two-year trees. V.'e have 25 clonal stocks of apples, several of which are used for the apple varieties. There is a total of nearly 1000 distinct lots of trees in our nursery. Is it any wonder that nurserymen sometimes make mistakes? A bulletin describing and illustrating nearly 100 varieties of apples is in press; one showing 42 varieties of cherries has just been published, and others dealing with pears and plums are in preparation. --J. K. Shaw MAGNESIUM DEFICIENCY The season is at hand when magnesium deficiency may show up in apple orchards. The typical symptoms are relatively easy to see although other causes may manifest symptoms which are quite similar. So one should not bo too hasty in assuming that a shortage of magnesium is necessarily the cause of a suspicious orchard trouble that merely "looks something like" the symptoms described for magnesium deficiency. In late July or early August, apparently healthy trees will suddenly show leaf scorch in the form of irregular brown blotches. These blotched sec- tions along the leaf edge or more likely on the blade itself are dead areas and naturally interfere with normal leaf functions. The older leaves n^mr the -8- bases of the present year's shoot growths are affected first, but soon leaves farther up the shoots may show the trouble. Affected leaves often drop off, and branches which appeared normal in June and early July may lose all their loaves by mid-September except for a few close to the tips of the shoots. Some- times, hov/ever, the scorched leaves seem to cling tenaciously, especially on older trees, and more often with some varieties than others, spur leaves are likely to scorch severely without dropping. Yellow banding aoid mottling of leaves are symptoms of the deficiency with some varieties, but not so much with our main varieties, Mcintosh, Baldwin and Dolicious. Magnesii^m deficiency not only seems to increase preharvest fruit drop but "hormone" harvest sprays are much less effective on such trees. As reported before, magnesium deficiency is usually associated with acid soils although this is not necessarily the case. Also, heavy use of potash has seemed to increase the trouble. Suggested control measures include the application of adequate amounts of high magnesium limestone worked into the soil if possible, plus the supplemeiitary use of magnesium sulfate (Epsom salts) or some other soluble magnesium compound. Hov/ever, this deficiency has been somewhat difficult to correct in England ajid Canada where it has been recognized for a number of years. It yields less readily and less quickly to treatments than deficiencies of nitrogen, potassium, or boron, for example. For some reason, affected trees are slow to take up added magnesium. It is important, therefore, that growers determine as soon as possible if their trees are affected with this deficiency so that control measures can be started. Experiments are under way at Massachusetts Experiment Station and else- where to determine the effectiveness of various treatments. — Lawrence Southwick HARVEST SPRAYS AND DUSTS In 1942, spray and dust applications to control prteharvest drop vrere compared in the Experiment Station orchards at Amherst on Duchess, Vfealthy, and Mcintosh. Applications on mature Mcintosh consisted of about 30 gallons of spray and 3 pounds of dust, and on Wealthy and Duchess similar liberal appli- cations according to tree size. The following selected data give a good pic- ture of the results in general. Spray concentrations are 10 parts per million (p. p.m.) unless otherwise noted.

On Duchess and Vfealthy, dusts v/ore less effective than sprays. 2. On Mcintosh, results vath dusts were somewhat more favorable than on Duchess and IToalthy. 3. Two successive applications of dusts or sprays resulted in better control of preharvost drop than single applications. 4. Increasing the concentration of the active chemical in sprays gave better results on Wealthy* It is suggested that grov/ers in this state do not dilute conmiercial drop-control materials belov; standard strength. In general, spraying may be expected to be more reliable than dusting. Both sprays and dusts should be applied during hot weather if possible. Spraying in the middle of the day is usually best while dusting in the early morning when foliage is wet v/ith dev; may be advantageous. —Lawrence Southwick MODIFIED RECIPES OF OLD TIME IMT ENGLilND PRODUCTS V^LL SAVE. SUGAR > ' ■ ■ • ' ' Many New England farm families having available cull apples, a cider press and some means of evaporating the cider such as a maple sugar pan, can make themselves all the sweet syi'up or sweet apple sauce they can use this winter. Apple cider when it is freshly made fi:*om sound apples contains between 10 and 135= fruit sugars, and about one half of one percent of fruit acid. Jf six quarts of cider are concentrated by boiling to one quart, a s^/rup will re- sult which contains about 60)o sugar and about 3;^ acid. This amount of acid ia too much for most people's taste and it masks the natural sv;eetness of the syrup. The acid can be eliminated very simply by adding l/2 level teaspoonful of balcing soda per quart of fresh cider. After the soda is added and the foaming subsides, the cider should be boiled down to a syrup v;hich should be filtered through cheese cloth, heated to boiling, and filled into pint jars or bottles which are sealed and processed in a boiling v/ater bath for 15 minutes. ■ 10- For the production of apple syrup in any quantity it is suggested that a maple syrup pan or evaporator be used. Care is necessary not to cara- melize the juice. About l/3 to l/2 ounce of baking soda per gallon of fresh cider is required to partially neutralize the acid. The syrup is ideal for pan cakes, v^affles or for any use for which maple syrup or corn syrup is com- monly used. If held through the winter it can be used for canning acid fruits and berries next season. Following are a few suggested recipes: Sweet Hew England Boiled Cider Apple Sauce. Take 1-^ pounds of firm, medium tart, solid apples; peel, halve, remove cores and cut each half . in quarter slices. Cook these slices slowly in 1 cup of the above syrup for 10 minutes in a sauce pan with lid on. Pack the apples in pint jars and cover v/ith the syrup they have been cooked in. Seal and process in boiling v/ater bath for 15 minutes. New England Apple Butter (without added cane sugar). Take 12 pounds of solid, tart apples (Baldwins, Spys, etc.). ViTash apples, cut out calyxes, halve, remove seeds and cut into thin slices. Cook in large kettle with one gallon of sweet (unconcentrated) cider. V.Tien thoroughly soft, put through colander or sieve. Return pulp to pan and concentrate by boiling until quite thick. (Use care or it will burn.) Vihcn thick add 1 quart of sweet cider syrup and 1 tablespoonful of cinnamon and -^ tablespoonful of cloves. Continue cooking with constant stirring until the boiling material v/ill heap up well on the spoon and flov; from the spoon in sheets. Pour the hot butter into clean., dry jars, and seal and process in a boiling v;ater bath for 15 minute s^ Please note the follovdng: 1. Only freshly prepared sweet cider contains the sugar necessary in the preparation of this syrup. Fermented or old cider v/ill not make a sweet syrup. 2. Do not use benzoatcd or preserved cider. A bitter syrup will result if preserved cider is concentrated. 3. The addition of too much soda will cause the cider to turn very dark. If this darkness is caused by soda alone, the addition of more fresh cider will brighten the syrup, 4. Be careful not to burn or caramelize the syrup. The finished syrup should be a light red and hsive a sweet apple flavor v;ithout a pro- nounced caramel taste. 5. Do not attempt to concentrate cider in a container vihich has an • exposed iron surface. A black syrup v/ill result.

It will therefore be highly desirable tiat time be taken at the start to instruct these new workers in the easiest and best way of removing apples from a tree. Let's not assume that the newcomer knows just how vre want the apples handled. In the rush of getting the apple crop picked in a few days, many grow- ers are in so much of a hurry that they give the new picker a basket and ladder, and tell hLm to "go to it." IVhere apple pickers are paid by tho bushel, there is a strong urge to got off just as many bushels as possible in a day without Issued by the Extension S'.rvice in furtherance of Acts of May 8 and, June 30, 1914, V/illard A. Munson, director, Massachusetts State College, United States Department of Agriculture, and Goimty Extension Services cooperating. -2- too much regard for bruises or pulled stems. It may be a good idea to pay a liberal hourly wage the first day, and then go on a bushel basis the second day. If at all possible, an experienced picker should supervise the work of not noro than 8 or 10 inexperienced pickers. To send out a group of high school boys without previous instruction or adequate supervision is one of the easiest ways to reduce the value of the crop. No factory superintondent would think of breaking in a nev; worker that way. First of all, a new picker should be shovm how to separate an apple from the spur, v/ith the stem intact. The stem will separate easily from the spur if the apple is tilted upward instead of being pulled off. And instead of pressing the fingertips into the cheek of the apple and giving it a pull, it is an easy matter to cup the apple in the pain of the hand and break it off with a lifting motion. Not more than tvvo apples at the most should be held in the hand at one time, and then only if they can be held without touching each other. The apple is then laid into the basket or pail and not dropped into it. Speed in picking does not require pulling apples from the tree nor dropping them into the container. Some of the fastest pickers harvest fruit which shows the least bruises. Then, such simple matters as picking apples from the lower part of the tree first should be stressed. All apples v/ithin reach of the ground should be picked before placing the ladder. This prevents bruising from the ladder it- self or through dropping apples from higher branches. In placing a ladder, caution the new picker about setting it evenly on the ground and always against a stout branch, and not at too great a slant. Even though the picker is not too concerned about taking a tumble, explain to him that ladders cost money and are not easily obtained. Also, advise against trying to pick from the ladder, apples which are almost out of reach. Reset the ladder, if for only a dozen apples. Patience, tact, diplomacy, and occasionally firmness will be needed with those new pickers. Pay them well and at the some tine help them to help themselves in doing an important job. NURSERY INSPECTION - 1943 For the 23rd consecutive year, men from the Massachusetts State College have completed the examination for trueness-to-name of nursery fruit stock in the Northeastern part of the country. This year 18 nurseries located from New England to Michigan and Virginia v;ere examined and misnamed trees correctly named or cut down. The report on a rather large nursery of an examination for the first time reminds one of the old days when we really found misnaraed trees. Repeated visits al^vays greatly reduce the number of mixtures, and smaller nur- series may be found completely free of misnamed trees. In some nurseries all salable stock was examined and in some only certain fruits were gone over. Peaches are in a class by themselves. Unlike other tree fruits, certain var- ieties are so much alike in the nursery row that they can ba identified only with difficulty or not at all. Nevertheless, many misnamed trees are detected. A list of the nurseries examined may be obtained on request from the Department of Pomology, Massachusetts State College, Amherst, Massachusetts. J. K. Shaw NOTE: The Fruit Notes mailing list is in the process of being revised. If l'^ou have received a letter (on pink paper) regarding the revision and desire to con- tinue receiving this publication, be sure it is properly filled out and returned to the Mailing Room, c=J_)iy ^o-u- /\ n^^ : J That the principal subsistence of the United States comes fron about 30 crops? All told, our farmers grow about 300 different crops. Tliis is about the average of temperate zone nations. China, on the other hand, produces and harvests about 6^000 different plants of nutritional value, which is one reason v;hy that country has been able to survive the Japanese onslaught. That allowing pears to remain on the tree until sufficiently mature reduces the astringent properties, tendency to wilt in storage, and on suscept- ible varieties, scald in storage? Leaving the fruit on the tree too long causes deterioration in quality and may cause trouble in storage or transit such as core breakdown and too rapid softening, f'ruit rots are generally more prevalent in pears that are harvested and packed when too mature. That the term "Horticulture" originally referr«d to the grov;ing of crops within walls as distinguished from the growing of crops in open fields? Today the term relates to the cultivation of gardens or orchards, including the growing of vegetables, fruits, flowers, and ornamental shrubs and trees. There is no hard and fast line of distinction between horticulture and agriculture although the wheat or corn farmer is strictly an agriculturist, while tha grow- er of any of the specialty crops, vjhether for food or ornamentation, may be considered as a horticulturist, That mid-day seems to be the ideal time for applying hormone sprays? Preharvest sprays containing napthalene acetic acid used on V/illiams, Delicious, and Stayman Vfinesap apples v;ere more effective v/hen applied at certain concen- trations at mid-day than at mid-morning, according to L. P. Batjer of the Bureau of Plant Industry, Beltsville, Maryland. He found that early morning sprays required nearly an hour to dry compared with a half hour at noon, but that apparently absorption was much more rapid at the higher temperatures. 75° F. may represent the critical point above which the temperature may not be an important factor. That no less than 7 different brands of materials intended for prevent- ing preharvest drop of apples are advertised in one of the fruit magaisines? All of these materials contain the same essential ingredients and all may be expocted to produce similar results if properly applied. None of them may be relied upon to give good results if haphazardly applied. That borax applications on apple trees susceptible to internal cork tend to reduce the preharvest drop of fruit as well as the drop through harvest, aa compared to trees not receiving borax? An application on trees previously free from internal cork, has no apparent effect on the dropping tendency, ac- cording to experiments performed at Ithaca, New York. That about Z^ million pounds of applq syrup were m^de in 1942? This year it is hoped that at least 15 million pounds will be produced for the pur- -4- pose of replacing glycerine used in processing tobacco. Tests at Michigan State College demonstrate the practicability of using dairy equipment in con- densing .apple juice. The dairy industry is becoming interested in apple syrup because this material can be substituted for sugar in the manufacture of ice creams and sherbets. One gallon of apple juice or cider can be condensed to 1 1/3 pounds of apple syrup. That methods for extracting and preserving the juices of small fruits for beverage purposes have been developed at the New York State Experiment Sta- tion at Geneva? Strawberries, raspberries, dev;berries, blackberries and elder- berries have been used in the studies and satisfactory products obtained, par- ticularly v.'here tlie different juices have been blended with apple juice. Because the small fruits generally come on v;ith a rush, making it difficult to handle the fresh fruits to best advantage, the possibilities of extracting juice from frozen fruits have been explored. With attention to certain details, frozen small fruits have proved to be an even more satisfactory source of juice than the fresh fruits. That water core is likely to be more prevalent in the fruit of trees bearing a light crop? An examination of the fruit of 7 Duchess troeo at Urbana, 111. by T/T. A. Ruth has revealed these facts: (1) On all the trees, v/ell colored apples and those v;ith red tinted flesh tended to show more v/ater core. (2) There was no correlation betv/een size of fruit and water core. (3) Apparently a high leaf-apple ratio favored the development of water core but various other factors were also involved. That softv/ood cuttings of beach plums taken in mid-June liave been rooted successfully when treated with a root inducing substance? V;. L. Doran and J. S. Bailey, using a rooting medium consisting of a mixture of 2 parts of sand to 1 part of peat moss, obtained 67% rooting on 4-inch cuttings of short new shoots or laterals treated v/ith indolebutyric acid. The basal ends were emersed for 4 hours prior to planting, and rooting v/as obtained in 25 days. That the utilization of commercial fertilizers in Nev/ England last year amounted to about A% of the total used in the United States? New England consumption amounted to 390,327 tons while that in the United States amounted to 10,005,238 tons. Massachusetts used 81,876 tons, or a little more than half as much as Maine where 153,442 tons were used. That the brilliant red color showing in the foliage of chokecherries for several weeks is due to X-disease, an incurable ailment of peach trees? Any grower planning to set peach trees next spring should first consider the d&struction of all chokecherries within at least 200 yards. That Hood River Valley fruit grov^ers are asking their employees to take lOfo of their pay in v/ar bonds? That each time a IS-inch gun is fired, 120 pounds of nitrogen goes back into the air from which it originally came? -5- "HOPJiOlffi" SPMYIHG Aim DUSTPIG FOR LESSEIIIIIG PREHAir/EST DROP ITith tlie Mcintosh harvest season near at hand, the follov/ing comnents and suggestions concerning "ilormone" sprays and dusts may be of interest: 1. Sprays are probably somewhat nore reliable than dusts, 2, Apply spray on Mcintosh as soon as sound apples begin to drop. A second application 4 or 5 days later should increase effectiveness and will probably be Justified this year. 3. ViTith dusts, tvio applications are reconmended, 4, Spray, as nearly as possible, during the hottest part of the day. Ap- plications are not very effective when the air" temperature is balov/ 70<-' F, 5. Apply dusts vrhen air is quiet, preferably when trees aro wet v;ith dev; and during hot weather, 6, Use plenty of material. Thirty gallons of spray or three poimds of dust are noni3 too much for mature Mcintosh trees. Thorough coverage is abso- lutely essential, ~ 7. Use' spray materials at standard strength (10 parts per million). This strength is usually recommended by the manufacturer. For increased assurance of effectiveness, use 1^ to double the standard concentration, especio.lly when only one application is to be made, Hov/ever, the standard concentration is likely to be sufficient if the spray is applied thoroughly and under favorable weather conditions, particularly as regards temperature, 3. Do not use lower than standard strength spray, 9, If Mcintosh trees shov/ severe symptoms of magnesium deficiency, drop- control applications probably will not be effective, 10. Remember that after about 10-12 days following an application, the "sticking" effect may be dissipated, resulting in heavy dropping. This is especially true with Mcintosh and harvesting must be planned accordingly, -— Lav/rence Southwick IClG?IESrjM DEFICIEIICY Symptoms of magnesium deficiency are nov; prevalent in apple orchards. Dead, brown areas on leaves, often accompanied by yellowing, are tj'pical of the trouble. Growers who feel certain that this trouble is present at all in their orchards are asked to drop a card to the undersigned at Mass, State College, Vfe are endeavoring to get an estimate of the prevalence of magnesiijm deficiency in this state, La;;rence Southwick OUTBREAK OF SPOTTED TEITTIFORM LEAFMINER A general infestation of the Spotted Tentiform Leafminer has broken out in eastern Massachusetts orchards, principally in Middlesex County. Al- though all available reports on this insect state that "it has not been re- corded as doing serious injury," the foliage in several orchards in this area is already definitely damaged. Many leaves have 10 or more mines in them and there is some yellowing and defoliation. The mines are about •§■ inch long and ^ inch vdde, being pulled together in a fold or "tent" on the umderside of the leaf. .6_ The insect is named from the spotted appearance of the mine on the upper surface of the leaf v/here the chlorophyll is eaten in spots rather than completely. A similar leaf miner eats out the chlorophyll in the mines com- pletely and is called the Unspotted Tentiform Leafminer. The life history and seasonal history is very sketchily reported and apparently they have not been completely studied. References state that the moths emerge in the spring and the larvae pupate; in September, spending the v;-inter in the mines in fallen leaves, all of which indicates one generation annually. However, the iiife stations r eoeiitly observed definitely show 2, and perhaps 3 generations this year. On August 11 to 13, moths were emerging and laying eggs for a genera- ti')n T.'hich will develop in September and October. These moths "flew up" in clouds from the heavily infested trees resembling a bad infestation of leaf- hoppors in September, It is evident that the usual sprays of lead arsenate and sulfur have little effect on these leafminors since v;ell-sprayed leaves were badly in- fested, nicotine sulfate and probably other ovicidal sprays should be ef- fective but they must be timed carefully and applied thoroughly. Theoret- ically, 7 to 10 days after the moths emerge, at virhich time the larvae are hatching and starting their mines, v^ill be the most effective time to spray.

V/hitoomb PRESENT STATUS OF APPLE LE.'iF-CURLING IIIDGE The Apple Leaf-Curling Ilidge is now generally spread throughout eastern Massachusetts orchards. ITo practical control of this pest in commercial or- chards by spraying has been discovered due principally to the necessity for spraying the unfolding buds eacli 3 or 4 days during the egg laying period of the midge flies and to the migration of flies from tree to tree and orchard to orchard. Operations which v/ill reduce the abiindance of the insect and delay its establishment in nev/ly infested orchards are: 1. Spraying vrith oil emulsion or DN on the trunk and larger branches, especially within loose bark, cavities and crotches at dormant or delayed dormant application. 2. Broadcasting naphthalene flakes at rate of 2 pounds per 100 square feet under infested trees about blossom time. 0. Cultivating under the trees about blossom time, 4. Using nicotine sulfate in the calyx and 1st cover applications. 5. Pulling and burning v/ater sprouts during July and August to kill the second and third generation maggots. 6. Pland picking of infested leaves, especially on grafts and small trees. \i. D.

Roberts ^^i^^iil-^ 0^' TliB 1942 HARVEST Last year when nany types and .ages of individuals picked apples, the experiences of va rious growers are proving of great help in the 1943 harvest. Several growers have remarked that some of their most valuable pickers were husband and wife combinations. Together they finished the tree completely,, tiie man placing the ladder and picking the upper branches while his vdfe picked from the ground. Part time workers also did a good job in many orchards. Ambitious factory workers ^rho found it possible to put in throe or four hours picking apples in a nearby orchard cane to the orchard with a definite purpose in mind and made an excellent showing. In contrast certain people who spent 8 or 10 hours in the orchard picked less efficiently. A disastrous experience with a group of high school boys under no super- vision is \;orth mentioning. Experiences of this kind must be avoided this fall. One grower said that he hired 25 high school boys who in his absence staged a pitched battle with Fancy apples. The next day he "fired" all but one of the 26. Vifithout in any v;ay excusing the boys for their actions, the writer be- lieves that the grower v/as as much at fault as the boys. At least his ability as a tutor is subject to criticism. And perhaps he doesn't recall his ovm •teen age shortcomings. Another experience involved a group of junior high school youngsters Vifho v/ere transported to an orchard under the m.istaken notion that anyone could pick apples and were then told by the owner that he did not need them. To make matters worse, they v/ere compelled to walk home, a distance of about three mil-is. These youngsters are not interested in picking apples this fall. YJq must build good v;ill not only among consumers but among proapective pickers. Next year may be v/orse than this from the standpoint of getting efficient apple pickers. A fevj-firemen found their way into apple orchards last fall and did a first class job. Being accustomed to climbing ladders, thoy v/ere right at home picking the tops of trees. It is unfortunate that v/e haven't enough firemen in Massachusetts to pick the entire crop. One grower paid his pickers in part with apples, and v/ith good apples at that. One paid a bonus to pickers v;ho stayed through the season. Still another rev/arded his key men in a special v;ay during the picking season. Un- able, because of duties other than picking, to cash in on the good wages received for piece work, thoy gained through a substantial voluntary "raise," YIe pass these ideas along for what they are vrarth» October 21, 1943 Prepared "by the Fruit Program Conimittee of the Extension Service I, W. H. Thies, Extension Horticulturist Contents The Mbuse Situation in Massachusetts Orchards Strav:berries in the Falnouth Area Do ifou Know? The Time Factor in Fruit Growing The Fruit Situation as Related to 1944 Food Production Goals Ceiling Prices on Fresh Apples THE MOUSE SITUATION IN IIASSACHUSBTTS ORCHARDS Imagine setting 128 mousetraps on an orchard area of one acre, and catching 64 mice the first night and 30 the nextl That was the experience of workers in the Fish and Wildlife Service who conducted a recent survey- in a Brimfield orchard. This orchard has a heavy grass cover, and at the time of the survey in September, mouse signs v/ere very much in evidence. Quoting from a letter written by Robert M. Borg, September 29, "The mouse population in Massachusetts is high. There are more nice per acre in the western than in the eastern part of the state. Every tree base examined in all orchards covered, even where there was sparse cover, was in- fested with mice. And in one orchard in Franklin County out of 30 tree bases examined 12 trees were partially girdled. Many other orchards visited had a few trees partially girdled. The mouse population will vary from 80 to 100 or more to the acre. In one orchard near Brimfield actually 9imicG per acre vrere trapped. This high population is due in general to a favorable growing season, hence good cover and food conditions. With the present high population of mice, and if weather conditions are favorable, the m.ouse popu- Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, Willard A. Munson, director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. ■2- lation may reach extromely dangerous and damaging proportions. Orchardists should check their orchards immediately after the apple crop is harvested and where girdling occurs, the orchard should be treated at once with zinc phosphide apple bait to reduce the population and eliminate further damage to the trees." In vievf of the large number of mice now present in our orchards, every apple grower in Mass. should place mouse control on the priority list, insofar as fall jobs are concerned. We cannot afford to lose vigorous young fruit trees at a time when maximum yields from our present plantings are urgently needed. Another job which should be completed even before we tackle the mouse problem, is that of finishing the apple harvest and getting the apples properly stored. October 25 should be the deadline for the apple harvest. In years past, too many apples have been lost by severe freezing in late October or November because they were either unpicked or left standing un- protected in a shed. All marketable apples should be stored in a cool, moist, rat-proof building. If a suitable storage is lacking the apples should be sold before cold weather sets in. STRAWBERRIES IN THE FAL?:OUTH AREA Records have been assembled from four commission merchants by County Agent Bertram Tomlinson covering strawberry receipts from Falmouth growers for the years 1943, 1941, and 1939. The total shipments received by these concerns during the three years vrere as follows t 1943 - 419,800 quarts; 1941 - 652,515 quarts; 1939 - 938,606 quarts. The numbers of growers inr- volved were respectively, 109, 150, and 211, while the average numbers of quarts per grower were 3840, 4350, and 4450, From these figures it will be seen that the receipts of strav/berries in 1943 were less than half those in 1939, that slightly more than half as many growers were in the strawberry business in 1943 and the average number of quarts per grower was somewhat smaller than in 1939. These facts indicate a shortage of help and to some extent disappointing prices in previous seasons. It is estimated that the above data includes approximately 1^% of the Falmouth strav;berry crop. Based on these figures the 1943 Falmouth strav/berry crop was 35.6;^ below the 1941 crop, and 52,t belov/ the 1939 crop. The drop in acreage for 1944 is not expected to equal that of the pre- vious year. Strawberry growers on the whole made good returns on their in- vestment this year, and despite the labor shortage, every effort has been made to maintain production up to the 1943 level. In many cases, this is being done by holding over a greater proportion of the old beds than v/ould be done normally. Much depends on winter and spring v/eather conditions, but the crop outlook for 1944 is about the same as for this year. There has been a gradual increase in the quantity of berries shipped in the 24-quart crate which is now the most popular package. 84/t v/ere shipped in that type of container in 1943 and only 42.5,=^ in 1939, WANTED - BOYSENBERRY INFORI'L^tTION. Many Boysenberry plants have been sold in New England. A summary of growers' experiences with this new fruit will be of interest. If you are experimenting with Boysenberries in your garden or on a commercial scale please jot down on a penny postcard any com- ments you may have to offer and mail to thj' writer. That the output of 3,800 typical farms is required to load an average ship with Lend-Lease foods? The following list of items might constitute such an output: Eggs laid in one year by 230,000 hens; Fill: production from 6,000 cows for one year; Meat from 5,000 hogs; Lard from 27,000 hogs; 7/heat from 850 acres. That total fruit production in the U. S. in 1944 will probably be about 11^ smaller than in 1943? Prospects are that only the prune and grape crops will be larger, by 12 and llfo respectively, while deciduous tree fruits and grapos are expected to yield about ll/o less than last season. Citrus fruit prospects are about as favorable as a year ago. That large amounts of ammonium nitrate fertilizer are likely to be available for fruit grov/ers during the coming season? This material carries. about 33;o nitrogen or approximately twice as much as nitrate of soda. It does not keep well in handling and if stored should be kept cool and dry. This new fertilizer may be widely used in New England orchards next spring. That a number of items of farm machinery are no longer being rationed? An increase in the allocation of steel for farm machinery in 1944 has resulted in the removal of the following items from the rationing list, beginning Oct- ober 16: dusters, disc harrows, tractors, moldboard plows, cultipackers, land rollers, grain binders and threshing machines. All other heavy machinery is still rationed. That apple scab infection was so severe in certain unsprayed orchards this season as to result in almost complete defoliation by early September? 0. C. Boyd and Thomas Sprostoh report commercial losses from apple scab rang- ing from a trace to 25^^ in sprayed orchards, and 50-lOOj^ in unsprayed orchards. A few inexperienced grov;ers have attributed the browning of Mcintosh leaves and later defoliation to spray injury, whereas lack of scab control was large- ly responsible. That a total of 194,775 tons of lime, enough to make 3,900 car loads, is used every year in the United States in connection with agricultural in- secticides and fungicides? Fungicides make about 2/3 of the total or 125,000 tons, and the insecticides make the remaining 69,775 tons. In apple orchards where large quantities of sulfur are being used, without lime, the soil is becoming so acid that the growi^h of ordinary grasses and weeds is greatly re- duced. That the attempt to control harmful insects dates back to the early days of the Roman Empire? Caterpillars on fruit trees could be controlled, according to Cato, by moistening the tips of the twigs with the gall of a green lizard. Pliny recommended that the bones of a mare's head be hung on -4- poles around the garden to control canker worm. In Pliny's time, all inhabi- tants in the area v/hich is now the North Africa battle zone, were ordered to wage war against the locust. People were compelled to hunt the locust eggs and crush them, or to crush the young and adult stages. Neglect of this duty was punishable by severe penalties. That a nation-wide poll places the total number of Victory Gardens in 1943 at 20,000,0002 As a conservative estimate, all Victory Gardens grovm this year total about 4,000,000 acres and produced 8,000,000 tons of food. An estimate of 25,000,000 families did some home canning during the summer and fall) 22,000,000 Victory Gardens, a 10^i$ increase, is expected in 1944. That the decaying remains of plants exert a very beneficial influence by facilitating the penetration of rainfall on a sloping area? Careful measure- ments in Ohio showed that 5=l/2 inches of the total annual rainfall soaked into the soil in a cultivated field, while 13 inches soaked into a forest soil. In an orchard, we may approach the conditions of a forest floor by applying a heavj'- mulch and by improving the cover crop. That for the seventh consecutive year, American farmers set a new food production record in 1943? Nevertheless, there is not enough food in total to satisfy all the demands and there are definite shortages in a number of our favorite foods. The increases during the past seven years are indicated by the following percentages: 1937 - lOl^-^j 1938 - 103j^; 1939 - 106^; 1940 - 111^; 1941 - 115;^; 1942 - 126,1; and 1943 - 131/1. That about 5,000,000 pounds of dynamite are used annually for agricul- tural purposes? The various uses include ditching, land clearing, drainage, irrigation, stump blasting, and to a limited extent, fruit tree planting. Ditching constitutes one of the largest agricultural uses. That 59 soil series and eight land types have been recognized in Massa- chusetts. Glacial till soils are most abundant and of these the Gloucester series is the most extensive, comprising 20.6^'^ of the land area. Glacial outwash soils are second in expanse and of these the Merrimac is the most important, occupying 10.4,1 of the total area. A Key to Mass. Soils has re- cently been prepared by A. B. Beaumont, and is now available for distribution. If interested, ask for Special Circular No. 64. That a codling moth infestation is likely to be more severe on trees adjacent to a packing house where boxes are stored during the winter, or to a pile of apple wood? In one case where a Massachusetts apple grower cut down a number of old trees and piled the wood next to tho orchard, the infestation was so severe on adjacent trees that each apple showed one or more codling moth blemishes. The infestation was so heavy that the grower removed the entire crop from these trees during the summer and destroyed it. That a mulch of straw or other suitable material on a strawberry plant- ing may increase the yield by at least 50l? The ideal tine for mulching a strawberry planting is about the time the ground freezes. In most localities this means early November. If mulched too early there is some tendency to smother the plant and if mulched too late there is likely to be some crown injury from low temperatures. -5- That detailed information is nov/ available on the freezing of fruits, vegetables, and meats for home use? A mimeographed publication, Special Cir- cular No. 1043, can be obtained ft-om your county agricultural agent or from the State College. At least three new frozen food locker plants have been made available in Mass. during the past season. In addition quite a number of in- dividuals have installed lockers for private use. That complete immunity to ivy poisoning is rare? L. V/. Kephart of the U.S.D.A. says, "l\'y poismLng is caused by a waxy or gummy substance present in most parts of the poison ivy plant even after long drying. Direct contact with this substance is necessary for poisoning to take place, but contact need not necessarily be with the plant itself, since poisoning may occur by touch- ing clothing, tools, dogs, horses, or other objects v/hich have been in contact with poison ivy. Many persons b elieve themselves immune to ivy poisoning, but complete immunity is rare. Severe poisoning frequently occurs after many years of freedom from the disease, although the circumstances causing this change are unknown." That an excellent series of articles on Rodent Control by Robert M. Borg is nov/ appearing in the American Fruit Grower? A heavy mouse population, amounting in one orchard to 94 per acre, threatens severe damage in Mass, orchards. Now is the time to do something about it. To obtain the recommend- ed material, zinc phosphide, and directions for its use, consult your county agricultural agent. That the term, "ready to bear" fruit trees is a misnomer? Any nursery advertising such nursery stock is deceiving the prospective buyer by inducing him to believe that certain nursery trees, usually sold at a high price, will bear a good crop the first year after planting. Any experienced fruit grower knows that it takes considerable time for a fruit tree to become established and that any fruit borne the first or second year is likely to be borne at the expense of vegetative grovrth. The apple or two borne the first season is less significant than the bushel or two v/hich it may bear at 8 years of age. THE TIl'IE FACTOR IN FRUIT GR07JING Through the centuries poets and philosophers have stressed the import- ance of grasping opportunities as they pass instead of lamenting their loss afterwards. "There is a tide in the affairs of men which, taken at the flood, leads on to fortune - -" . "Strike while the iron is hot." "Tim.e and tide wait for no man." Nowhere is the truth of this philosophy better illustrated than in the fruit business. The fruit grov;er cannot do in November what he should have done in October. A few illustrations may be in order. Mouse bait must be applied before the mice have turned from a diet of grass to a diet of bark. If curculio are most active on May 30 it doesn't do much good to apply a first cover epray on June 2. A hormone spray will be infinitely more effective if applied a day before the Mcintosh crop shows a heavy drop than a few days — later. Yife have all seen farmers who get around t o start haying operations in mid- July while a thrifty neighbor- has his haying completed by July 1. As we look forward to a busy 1944 we may well keep a calendar and so far as possible do today those tasks v;hich should not be put off until tomorrow. -6- THE FRTTIT SITUATION AS RELATED TO 1944 FOOD PRODUCTION GOALS At a Food Production Conference held in Amherst October 13 and 14, attended by representatives of all interested farm agencies and organizations, Massachusetts goals in each comr.'iodity were carefully considered. The Fruit Cominittee submitted the following report: Apple Production in Massachusetts The apple crop in 1942 amounted to 3,400,000 bushels. In 1943, it amounted to 2,552,000 bushels while the 1934-1941 average amounted to 2,484,000 bushels. In 1944 we nay reasonably expect a crop somewhat larger than in 1943 although not as large as the record crop of 1942. The 1944 crop nay total approximately 2 3/4 million bushels. This estimated increase over 1943 vj-ill be due in part to a larger prospective Mcjntosh crop and to the fact that next year is the "on year" for the Baldwin variety in many orchards . Unlike nost vegetables, and to a certain extent, eggs, apple production caruiot be greatly increased over a period of a year or two, even under the best orchard practices. The number of fruit buds vdiich may develop into apples in 1944 was determined several months ago, VJeather conditions at blossoming time and also the amount of nitrogen available to the tree will be important factors in the actual set of fruit. The apple grower can, of course, greatly influence the percentage of apples which develop to maturity since he has at least par- tial control over insects and diseases. He can also influence the number of bushels to som.e extent as he increases the size of individual fruits through fertilization and mulching. The goal of the Massachusetts apple grower in 1944 will be to produce maximum yields on present plantings. To do this Vifill not require saving every tree in the state regardless of age, height or degree of crowding. In many orchards high production of m.arketable fruit will be greatly favored by re- moving filler trees. In many cases this will involve cutting out every other diagonal row. In older orchards where the trees are too tall to be sprayed and harvested efficiently the tops should be lowered by pruning. Since labor is such an important item in apple production our orchards should be put in order. This is an ideal time to lay plans for more efficient spraying and easier harvesting in 1944, Weeds of T'assachusetts Fruit Growers Equipment. Difficulties in controlling apple scab in 1945 err:phasize the need for both spraying and dusting equipment. Every fruit grower nust of necessity have a good sprayer. Any grower with 20 acres or more should also have a good duster. Since dusting can be done with less time than spraying, and since it provides needed protection at critical tines, dusting should be considered as a necessary supplement to spraying, particularly in our larger orchards. We will need 100 percent as many dusters as were delivered in 1940, We will also need at least 80 percent as m.any sprayers as v/ero delivered in 1940. Sprayer and duster repair parts nust be made available. Growers report that repair parts were very slow in being delivered last season. A good sup- ply of all needed parts must bo made available for prompt delivery, including -7- scarce metal parts such as stainless steel balls, aliiminum heads for spray- brooms, etc. T/herever such parts are needed u strong claim should be made by the interested grower. A considerable quantity of rubber hose will also bo needed for replacement on our older sprayers. All of these items should be ordered early. Early placing of orders will undoubtedly influence the nuraber to be delivered and will also insure having the equipment in v/orking order at critical times. Spray and Dust Materials. Supplies of all needed insecticides and fungicides for 1944 appear to be adequate, although manpower will be a critical factor in their manufacture. Distribution may be a factor. This emphasizos the need for fretting orders in early. Standard materials including lead arse- nate and sulphur are not likely to bo more restricted than in 1943. Not enough p^rrethrum was available last year for use on cranberry bogs. In view of this fact, more pyrethrum should be made available in 1944. Fer-'-.il izers t. If our orchards are to produce to the limit of their capacity wt- nvx^z have enough nitrogen to maintain ^ood tree Arit^or and to de- velop the 1944 crop. Certain forms of nitrogen, pr.rticu-arly :u.imoaium nitrate, will apparently be available in quantity. Arrangements must be m&de to re- lease enough nitrogenous fertilizers at tne right season to S'Vizlj- our orchard needs. Fall application of nitrogen is not recommended. Iheru is danger of winter injury at this latitude from such treatment. Farthe:.- sov;th that danger does not exist. For this reason our growers must have an adequate supply of nitrogen for early spring application. Where sufficient nirrcgcn for a broad- cast application is not available, a ring application is recommended. The wider use of nitrogen in impoverished orchards will help to attain the fruit production goal in 1944. The supply of phosphorus will apparently be ample for orchard needs. Potash will be scarce, although this will not greatly handicap our growers since Massachusetts orchards, in general, are well supplied with potash. Most growers can well afford to release potash supplies for other uses. A liberal potash application tends to encourage magnesium deficiency. Symptoms of mag- nesium deficiency are now very prevalent in many orchards. The general use of high magnesium, or dolomitic limestone, is therefore recommended. Liming of orchards can best be accomplished through the AAA Program. Dolomitic lime in bulk shipment, spread by means of an end gate spreader, will constitute a valuable addition to the orchard fertilizer program. Mulching is also strongly recommended. Marketing. No particular problem can be foreseen at present, Packages. More wooden boxes will be needed in 1944 than in 1943 on account of the larger prospective Mcintosh crop. Containers made from substi- tute materials are entirely unsuited for storage use since they do not hold up under the high humidity conditions existing in a storage. Higli priorities should be given to v/ooden containers for all fruits including apple boxes, cranberry boxes, strawberry crates, peach basketc, etc. Delivery of apple boxes should be made before July 1, Transportation. Since fruits are highly perishable, and during peak seasons the fruit grower is dependent upon truck transportation, trucking -8- facilitiss must not be reduced in 1944. Storage. In view of a somewhat larger crop in 1944 more storage space will be needed than was available during the past two years. To prevent the waste which occurred in 1942, amounting in some localities to 10;;? of the crop, adequate storage facilities for the 1944 crop are imperative. Labor. Fruit growers will benefit greatly by the arrangements now being worked out wEich will permit experienced workers to transfer to another essen- tial industry during the off season and later return to the fruit farm when needed. Labor requirements, except during the harvest season, should present no more of a problem than in 1943. Harvest labor needs are likely to be greater in 1944 because of the larger prospective Mcintosh crop. These needs should be thoroughly surveyed during the summer. Consideration should also be given to the discovery and training of crew bosses in advance of the harvest season. Our experience in recruiting and placing harvest labor in 1943 vidll prove val- uable in 1944 when labor conditions are likely to be more difficult than they vifere this season. J4any growers have expressed their appreciation of the ef- forts of Labor Coordinators, Extension Service workers, newspapers, etc. in helping to solve the harvest labor problem. Ladders and Picking Baskets. These items were scarce in some locali- ties in 1943 and plentiful in others. In order to accommodate larger numbers of pickers on weekends and other ruch periods fruit growers must provide them- selves with extra ladders and containers. Early orders and wider distribution of these items will facilitate the 1944 harvest. Credit. Present farm credit facilities are adequate. Price Supports and Ceilings. In vie^v of the fact that present ceiling prices are established at levels lower than those at which apples were moving freely, support prices not far below the present ceilings are recommended. A satisfactory price will provide an effective incentive for maximum production in 1944. CEILING PRICES ON FRESH APPLES Following is an abstract of a statement on this subject, prepared by Ellsv/orth W. Bell: Ceiling prices on sales of fresh apples have been established by Amend- ment 9 to WR 426, effdctive October 7, 1943. This order covers any and all apples for TABLE USE except the Lady variety and crabapples. Apples for pro- cessing are not covered by this order and, in the opinion of the Regional Office of the OPA, establishes one price for table apples of all kinds, varieties and packs, whether loose-packed, wrapped in individual wrappers, gift wrapped, or in any other form. For apples sold by growers and delivered to retailers, insitutional users such as hotels, restaurants, schools, etc., government procurement agen- cies and other persons, except to ultimate consumers and intermediate sellers, the prices in Table 1 will apply for less than carlot sale (L.C.L.)* and less than trucklot sale (L.T.L.)* For such sales by growers, delivered to inter- mediate sellers (persons who buy for resale to retailers, institutional users and other persons except ultimate consumers), the prices in Table 2 will apply. For sales of carlot (C.L.)* or trucklot (T.L.)* quantities of apples produced in and sold in New England, delivered at any terminal market or whole- sale receiving point (except C.L. or T.L. shipments by C.L. distributors or brokers), the prices in Table 1 and 2 less 1^ per pound shall apply, depend- ing upon the type of receiver. For example, the grower's ceiling price will be figured as follows: (1) Growers making C.L. or T«L. sales, delivered to a retailer, uses Table 1 price schedules less 1^ per pound. In other words, under Table 1, a C.L. or T.L. sale of 40-pound containers v;ill be 40/ lower than the $2,85 price quoted for similar containers in October. (2) Growers making L.C.L. or L.T.L. sales, delivered to a retailer, uses the ceiling prices indicated in Table 1, (3) Growers making C.L. ©r T.L. sales, delivered to an intermediate seller, uses prices indicated in Table 2, less 1/ per pound. (4) A grower making L.C.L. or L.T.L. sales, delivered to an inter- mediate seller, uses the prices indicated in Table 2. For a grower making a C.L. or T.L. sale not delivered at any terminal market or wholesale receiving point, for example at his farm, there appear to be no pricing provisions in the language of this order. The price ceilings prevailing in this type of selling (f.o.b. farm), is being worked out and an- nouncements will b e made later. For sales by growers to the ultimate consumer, the schedule of prices in Table 3 will apply. These prices apply to Zone 1 which covers all of the North Atlantic states, all of the East-North-Central states, with the exception of certain counties in Michigan and Wisconsin, and all of the South Atlantic states with the exception of Georgia and Florida. These ceiling prices cover all types of sales by growers, made by parcel post or express, as covered in the footnote under Table 3, *A carlot sale (C.L.) or a trucklot sale (T.L.) means a quantity of fresh apples transported in one car or truck or other conveyance at one time out of which 75% or more by weight is sold to one person. The sale of the remaining quantity to another person may be considered a less than carlot sale (L.C.L.) "or less than trucklot sale (L.T.L.). For example, if a truckload of 100 bushels of apples is sold to one person, the sale would be considered a trucklot and v/ould take the ceiling price for such a quantity. If 80 bushels were sold to one person and 20 bushels to an- other person, 80 bushels would be considered a trucklot sale and the re- maining 20 bushels would be considered a less than trucklot sale. On the other hand, if 70 bushels or less than 75^ were sold to one person, and the remaining 30 bushels to another person, the entire load, accord- ing to the order would be a less than trucklot sale. A 75% figure would apply to any quantity of apples sold, whether 50 bushels or 500 bushels, if transported in one car or truck. »4 u . 1 (U t> l» 3 fi u, t) 04 u S (Vh O 1 SO ^ ^co >!* -iO u <»H O 1 ^ XO^spO ■P wo 10 ^ Cm C!

Ilovie Films Available at il.S.C. eport on the Boysenberry Correcting Magnesium Deficiency Questions and Answers on Apple Price Ceilings GOOD ADVICE ON APPLE I-IARKETING The follov^ing statement comes from John Chandler, Sterling apple grower and Executive Secretary of the National Apple Institutes "At the risk of being called visionary, your Secretary vdshes to make a suggestions which he believes will prove practical in the long run. The combination of a very short apple crop, a greatly accelerated demand, and the preclusion by the apple price ceilings of realizing higher prices for fine packs is tending to discourage careful grading and packing. At the same time, the definite and substantial periodic mark-ups in the ceiling regulations are tempting growers to v;ithhold their apples until the last possible moment. Unfortunately both of these practices are working against the years of work which all of us have put into building a greater demand for apples. If there are per- iods during which the housewife cannot buy apples at all, and if, v;hen she can get them, they are not of the quality, size or condition she wants, her thoughts will turn to other foods and v/e will have crossed a good customer from our list. By the sai.ie token, the store manager, the distributor and all those who depend on regular supplies of apples will lose their interest in our product in some degree. Would it not be better if v/e all undertake to supply our usual trade with a normal supply of properly packed apples? This ivill mean some financial sacrifice. Yes. But let us remember that we are experiencing an extraordinary year, in v;hich most of us can earn a fair profit, even if v;e pack and sell in the Issued by the Extension Service in furtherance of Acts of Hay 8 and June 30, 1914, Vi/illard A. Ilunson, director, Ilassachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. -2- nornal way, and particularly let us remember that other years are coning, years of large yields when, regardless of ceilings and mark-ups, none but the best v;ill command the naximuni price and when vj-e will be obliged to sell when the market can absorb our apples regardless of mark-ups. Then we will need our outlets, our cus- tomers and their good will. VHiat was that parable about the goose that laid the golden egg?" V;iIlTER INJURY TO GRAPE VINES That grape varieties differ widely in their relative susceptibility to severe winter tempera tures is shown by the results of an examination of the Col- lege vineyard last spring combined with a study of yields this fall. During the winter of 1942-43 there were two periods in Amherst whenihe minimum temperature was abnormally low. The first of these periods came on Dec- ember 20 and 21 when the minimum temperature on both dates vms 15 degrees below zero. The second period came on February 15 and 16 Virhen the minimum temperature was 19 below and 23 below, respectively. Vihile some injury may have occurred in December, the greater portion of it probably occurred in February, From the fol- lowing observations on the relative amount of injury it will be noted that Concord, ¥/orden and Fredonia withstood the lovj temperatures remarkably v/ell. Agawam - Practically dead, Athens - Vine 50/o injured, Brighton - Vine 505;o injured; also remaining blossom buds injured, Brockton -Canes all injured; trunk O.K, Bronx - Trunk dead, Buffalo - On one vine, 25^j of canes injured; on other vine, trunk dead.

The total value is about ^9,764,000 or 900,000,000 ration points. That peach and apricot pits may be transformed into charcoal which is very satisfactory for use in gas masks? Extensive tests of this material have recently been i.iade in Oregon. That the Delicious apple is probably the most important variety in the United States? This variety occupies more acres than any otlier and is more v;ide- ly distributed. Its comi-ianding position is due in part to high quality and to the publicity it has received. That the total business of the 900 fruit and vegetable cooperatives in the United States last year amounted to 325,000,000 dollars? This year's total tonnage, packed largely for military and lend-lease purposes, will be much larger. That the yield of pecans from wild or seedling trees in the United States exceeds that from trees of improved varieties? iiore than 56,000,000 pounds of pecans were harvested from the v/ild or seedling trees last year while less than 48,000,.000 pounds vj^ere harvested from trees of improved varieties. That approximately 2,000,000 bushels of Fancy or higher grade apples in Vfashington and Oregon have been ordered set aside by the \'iFA to meet the require- ments of the armed Services for fresh apples? The regulations require all per- sons who own (on or after November 6) 500 bushels or more of apples grown and located in either of the tv.'o states, which meet the respective state standards for Fancy or higher grades, to set aside 15 percent of each variety of these apples for purchase by the armed services or any other governmental agency spec- ified in the order. That British scientists i/orking on the fruits of the Rugosa Rose, which is used in that country as a hedge plant, have found it to be even higher in Vitamin C than oranges? As a result they are using it to make marraalades and vitamin concentrates to fortify the lack of these elements in wartime diets* A. Li. Davis That the Plov?eringquince, sometimes called Mexican Firebush, and more conimonly referred to as Cydonia japonica (now correctly Chaenomeles japonica) , produces occasional fruits which are not altogether satisfactory for flavoring, but will make a good jelly? A mixture of the fruits of the Japanese 'quince, sOjCalled, and either our native apples or some other fruit such as some of the flowering crabapple fruits, produces a d elicately flavored and delightfully colored jelly. __.;^. h. pavis -4- MOVIE FIUIS AVAIIJiBI£_ATJ4^^SACJ2JSmS_^Sm^ Ilovie films on a wide variety of subjects may be obtained through E.

It shows what goes on in an up-to-date research laboratory during the development and critical testing of new fungicides and insecti- cides as v;ell as the demonstration of the effectiveness of old, standard materials. The close-up color views of such pests as the house fly, the fruit codling moth, aphids, Japanese beetle, are interesting and even fas- cinating in most instances. It demonstrates very convincingly how important is a spreader or sticker when added to an arsenical spray for codling moth control. It leaves no question in the mind of the audience regarding the scientific training and experience, as well as the technical, accurate equip- ment that are back of the discovery and testing of fungicides and insecti- cides that are eventually placed on the market for us'e in pest control.

A drajTiatic movie illustrating the importance of agricultural production in the war effort. The story is built around a young man v/ho is on the home farm with his father and a brother who has lost his eyesight in the war returns. The young farr.ier decides to enlist in the ilarines because he feels he is not doing his part to help win the war. The blind young uan speaks at the Sunday service in the Village Church not on his experiences in the war, but on the importance of maintaining agricultural production on the home front. The deferred brother finally decides to stay at home and maintain production. Hade by Agricultural Extension Division of Du Pont, REPORT ON THE BOYSENBErJRY Two replies have been received in response to our request for information about the boysenberry, in October Fruit Notes. Report No. 1 (from New Hampshire): "V/'e have had boysenberries for several years, and under our conditions have found that practically all the canes winter-kill every year. The only ones that live through are those which are naturally covered by leaves or rubbish, which sometimes happens because they lie so close to the^ound, T/.e think that they are a terrible nuisance to take care of, and the production on the canes that live through the winter has not been overabundant. Taken all in all, I consider they have no com- mercial value and very little value even as a hoiae fruit. They should be classed a^ a novelty. This applies equally to Nectarberry, Thornless Boysenberry, and Thornless Youngberry, Of the whole lot, Boysenberry is probably the best," Report No. 2, "My attempt v/interkilled. Berry when ripe is like a skin full of water. Color bronze, yield light, but flavor fairly good. It may be different elsewhere and have some home garden possibilities," •5- CORRECTIilG lIAGHESIUII DEFICIENCY The use of magnesium sulfate spray applications on magnesium deficient apple trees at Hassachusetts State Collelge this past season has shown that this method may be a practical and effective treatment. Four special sprays v;ere applied to young trees in an orchard showing considerable foliage scorch and leaf fall in 1941 and 1942. Applications were made at approximately pink, calyx, first and second cover. The sprays contained 16 pounds of Epson salts per 100 gallons of water and were applied as special applications. Incident- ally, it is probably safe (although we have no definite data) to add the Epsom salts to the regular spray mixture thus largely eliminating any extra applica- tion cost for the magnesium. Compared with the check or unsprayed trees, those sprayed showed much less foliage scorch this fall. Of the 146 sprayed trees, 65% shov/ed no deficiency symptoms, compared to only 20yo for the sane nuinber of unsprayed trees. Beneficial effects of magnesium spray applications have also been reported from New York and llaine. Soil applications of magnesium canpounds have likewise showii promising results at Axiherst. Both Seawater liagnesia and Epsom salts applied at the rate of 5 pounds per small tree in the fall of 1942 were beneficial in reducing scorch prevalence and severity in 1943, These results are not in line v/ith experience elsev^here, where benefits have not been apparent for some years fol- lowing soil treatments. However, the trees at Amherst are young (just beginning to fruit) and are growing under a heavy mulch system of culture. It is probable that both of these factors have a favorable influence on the intake of magnesium from compounds applied to the soil. Tests in an older orchard gave nt indica- tion of benefit from the soil applications. In orchards showing serious magnesium deficiency, the application of magnesium in sprays seems to be a logical procedure. For instance, v/ith trees requiring 20 gallons of spray for adequate coverage, 12.8 pounds of Epsom salts would be provided per tree in the 4 applications described above. Thus, in addition to the imraediat-? corrective effect of a foliage application, the amount of magnesium applied (and most of it gets to the ground sooner or later) is equal to or even greater than that in the suggested soil treatment. Further experimental work is planned, but in the meantime growers should be doing something to correct serious magnesium deficiency conditions. V/here soils are very acid (and many orchard soils are), magnesium limestone should be applied and vrorked in, if possible. Lawrence Southvirick WANTED - APPLES OF OID VARIETIES.

(Key words in each «^uestion are underscored. ) 1. Q. To what point does the first ceiling on shipments of apples apply v;ithin a state? A. The first ceiling which applies to intra-state shipments is the carlot or less-than-carlot ceiling price in any terminal market or other v>rhole- sale receiving point. 2. Q. Is it perr.iissible to price loose apples by the bushel or packed by the box? A. No. Apples must be sold on a minimum "net weight basis. Under some cir- cumstances, apples may be sold by the bushel or in any other container, loose or packed, if the minimum net v/eight of the fruit is marked on the container, and the price charged is not more than the applicable ceiling price for that weight. 3. Q. Suppose a grower sells a trucklot of apples to a retailer making delivery in his ovm truck, would he then be entitled to the maximum price for sales to retailers? A. No. He is entitled to the maximuiii trucklot price for sales to retailers which is the same price as the maximum trucklot price to any other kind of purchaser. There is a carlot or trucklot ceiling price for every market, which is always the same price within the particular market for sales to any kind of purchaser. 4. Q. Under what circumstances can a grov>rer or shipper perform the functions of an interTiiediate seller and obtain the allov;ances therefor? A. The only circumstances under which a grower or shipper may obtain part or all of the intermediate seller's markup occur when he sells less- than-carlot or less-than-trucklot quantities delivered to a retailer or to an intermediate seller. 5. Q. If a person buys from three or four different grov/ers and makes up car- lots, is he entitled to the carlot distribution markup? A. No, In order to qualify as a carlot distributor a person must buy un- broken carlots and resell unbroken carlots. 6. Q. If a grower consigns apples to a cormnission merchant who sells in less- than-carlots to retailers is the grower entitled to the proceeds after deducting transportation charges and coinmission? A. Yes, but the grower selling through a commission merchant establishes his ceiling price by taking the carlot delivered price in the market or other wholesaler receiving point plus the usual commission of the commission merchant. The ceiling price is not permitted to exceed the applicable less-than-carlot price to retailers or to wholesalers. If a commission merchant sells in carlots, the price is the carlot market ceiling price. 7. (^. If a grovifer sells a half-car of apples through a broker to each of tv/o wholesalers or jobbers, what ceiling price applies? A. The ceiling price is the less-than-oarload" ceiling price for sales to intermediate sellers. -7- 8. Q. Is it permissible for the grower to add a brokerage charge to the f.o.b. ceiling price, when making an f.o.b. shipping point salet A. No, Brokerage may only be added when a carlot is sold delivered by a broker in the terminal market or other v;holesale receiving point, 9. Q. ilay a shipper or grower qualify as a carlot distributor? A. No. Original shippers are specifically excluded from taking a carlot distributor's markup. 10. Q,. Hay a chain store share with the original shipper in any of its markup out of the consumer retail price? A. No. 11. (ci. Vrnat is the maxiraun price a grovrer or grower's sales agent can quote to a chain store organization? A. If the gro\;er or his agent is selling f.o.b. shipping point in one of the states listed, Idalio, Nev; York, Oregon, Pennsylvania, Virginia, Vfashington and \rest Virginia, the grower's ceiling is the f.o.b. price listed. If the grower or his agent is selling carlots delivered in the market, the ceiling is the applicable less-than-carlot ceiling price to retailers less one cent per pound. If the grower is located in a state having f.o.b. ceilings, the ceiling for a delivered carlot sale is the f.o.b. price plus freight to the market or other wholesale receiving point. If the grov;er or his agent is selling less-than-carlot to an intermediate seller, de- livered in the market, his ceiling price is the applicable less-than-car- lot price. If the grovrer is selling less-than-carlot to a chain retailer, delivered to the premises from v/hich the retailer resells to consuiaers, the price is the less-than-carlot ceiling price for sales to retailers. 12. Q, Can a grov;er legally make an additional charge for boxes or other con- tainers? A. No, nor may a seller accept any deposit for any reason, whether he is trading in containers or lending the money to the buyer. 13. Q. IThat price ceiling applies for sales to the Anay or Navy? A. If the sale to the Armj^ or Navy is in carlots or truckl'ots , the ceiling price is the same as the carlot or trucklot ceiling price to any other carlot or trucklot buyer. If the sale to the Army or Navy is in less-thar>- carlot or less-than-trucklot quantities, the ceiling price is the applica- ble less-than-carlot or less-than-trucklot price for sales to retailers. 14. Q. Is a seller permitted to "roll a car unsold" in October for a market arrival and sa le in November? ~ A. Yes. If delivery (see question and answer 36) is made in November the November ceiling price applies. 15. Q. Are freight subsidies a part of the apple price ceiling program? A. Yes. Freight subsidTes on v>restern apples sliipped into eastern zones have been undertaken by the 17ar Food Administration. 16. Q. May the agent of a seller in his terminal market selling through an auction return to the grower any amount of excess of tiie commission or charge of the agent? A. There is a specific ceiling price for sales at auction. The seller may receive the proceeds of the auction sale less all auction charges, less the agent's usual commission and less any other charges. ^8- 17. (^. Do the inaxinuin prices to retailers and intermediate sellers apply on apples t^rovm and shipped from llichii^an or o^fTer states not covered by f.o.b, ceilings? A. Yes, 18. Ci. Do the maximum prices covering sales in an auction market apply to pur-i chases by an ultimate consuiaer in an auction market? A. Yea. 19. Q. Is there any allovmnce made for grower ♦S sales agents? A. Growers' sales agents obtain their maximum 'prices if they are making • sales f.o.b, shipping point, 20. Q, Can a subsidiary of a chain organiaation purchasing unbroken carlots legally add the carlot^STsTribution raarlcup when reselling unbroken cars? A. Yes, ' 21. q. Has any consideration been giv^n to price differentials for grades and varieties of applee to b« nvado by regional or" district' offices of the OPAf A. The regional and district offices of the OPA have the authority to es- tablish community ceiling prioes at the wholesale and retail levels, but ar.iendiaent 9 was not intended to provide a basis for the making of varietal and size differentials. 22. (^. In cases virhere it lias been the custom to add cartage for out-of-tovm deliveries to retailers or institutions, is it pen.iissible to add such chafijes to the maximum prices? A, No. The uniform zone prices established in araendir.ent 9 include nonnal delivery charges to the place where the retailer or institutional buyer is located. However, consideration is being given to provide higher less-than-carlot prices for delivery to retailers or institutions lo- cated substantial distances from primary receiving points where carlots or trucklots can be received, 23. (^. Define a commission merchant. A, A commission merchant is an agent of a grower or shipper, located in the terminal market or other wholesale receiving point, v/ho sells in less-than-carlot or less-than-trucklot quantities to wholesalers, i^- tailers or institutions, who usually sells through a store and extends credit and who remits to the grower or shipper the net proceeds of a sale deducting therefrom his commission and all other applicable charges, 24. Q. A grower takes a trucklot of apples to Cumberland, Maryland, and sells in 1 e_s s -than -truckl ot quantities to retailers. Does he determine hia maximum price by reference to the"Table covering sales to retailers? A. Yes. 25. (^. A grower does not have time to go to Cumberland, Maryland and visit each store to make sales, but he is in a position to sell in lol quantities by phone to the retailers. He loads hia truck and sends it to a central point where the apples are picked up by the buyers. He finds that sales of this kind are considered pool trucks, V/hy is there a difference in the ceiling price for this method of sale as compared to I'e s's-'than^oarl ot sales to retailers? ""^ — — — - -9- A. Because the expenses involved in making this kind of a sale are consid^ erably less than if the grower himself performs the function of selling delivered to the premises of the retailer. If the grcwer after having taken his phone orders, delivers individually to each retail buyer he takes the less-than-carlot price to retailers. 26, Q. Does a grower or shipper have the option of selling deli^rM^d to a mar- ket or f .o.b. shipping point in order to FEtain the highest possible legaT'return? A. Yes, but the grower or shipper will not obtain a higher return on any but an intra-state shipment (see question and ansv/er 34), 27. Q. In selling to truckers who come into the producer's area covered by the f , o'7BT'ceTlTng''Y"-"ceT"i s the grower allowed to sell at a price higher than the net f,o.b, ceiling price? A. No. 2a. Q. In selling the consuiiier a fev.^ baskets of apples, may the grov/er take the~ceil'ings on sales to consumers or does he have to make physical delivery? A. Delivery is not necessary. The grower in this case takes the ceiling for sales to consmaers. 29. <^, If a shipper sells direct to a jobber is the shipper entitled to the broke~age""or carlot distributor' 'al'l'owance? A. !!o. 30. Q. l/here a shipment is made from a point within a state covered by f .o.b. ceilings to another point v;ithin the same state, but crosse» another state's lines en route, is such sale an intra-state tale and -therefore not subject to the f,o.b, ceiling price? A, Such a sale is an intra-state sale since the point of ultimate delivery controls the price to be charged, 31. Q. Suppose a seller does not v;ish to weigh each box. May he take a repre- sentative sample? '~^ A. Any sampling runs the risk that the boxes will weigh less than the l«gal minimum v/eight. If a seller "guesses wrong" as to the weight, he is in *criolation, 32. Q, liay a carlot distributor invoicing buyers include brokerage providing brokerage is paid by the carlot distributor? A» Wo. The maximum price for sales by carlot distributors is the price set forth in paragraph (c) (2) of amendment 9 and no further addition may be made. In any one transaction, both the carlot distributor's markup and brokerage charge cannot be taken. These allovmnces are mutually exclusive. 33. I). IThat is the ceiling price for export sales of apples? A. Export sales of apples may' be made at prices which are composed of the domestic ceiling prices per pound, plus certain premiums for packing, ^lus freight. The Second Revised Export Price Regulation covers export sales of all commodities covered by domestic ceiling price regulations. -10- 34, Q,. \Then the terminal narket price is greater than the f.o.b. shipping point price"'pTus' fre'it^ht, 'protective services and other charges from the states having f.o.b. ceilings, does the higher terminal market price become the maximiun price? II. The delivered price in carlots or trucklots for any interstate ship- ments of apples from any one of the states having f.o.b. ceilings, is the fjo.b. ceiling price plus freight to tlie market or other whole- sale receiving point. The carlot delivered price computed by sub- tracting 1 cent per pound from the less-than-carlot or less-thai:i- trucklot price to retailers applies only to intra-state shipments in sta tes having f.o.b. ceilings and to both inter-state and intra- state shipments of apples from states having no f.Ocb. ceilings. 55, Q,. A carlot or trucklot of apples is placed in terminal cold storage by a grower under an arrangement that delivery to a retailer is to be made from time to time in less-than-carlot quantities, with the grower paying .cartage to the retail store, Would the maxii-ium price to re- tailers for the appropriate month and zone be the ceiling price for such transactions? A. Yes, provided that sales of this type are made to retailers in less- than-carlot quantities. 36. Q. IVhat constitutes "delivery" for the purposes of establishing a maximum price? A. There are four tests to be applied for the purposes of determining wlien title passes to the buyer and delivery has taken place. (l) If at any time delivery has been made to a carrier not owned or controlled by the seller, "delivery" has taken place^ (2) If at any time actual physical delivery has been made to the buyer, "delivery" has taken placer (3) If at any time the particular lot being sold has been car marked or citBnpletely segregated for the account of the buyer, "delivery" has taken place.' (4) If at any time there has been legal agreement between the buyer and the seller to the effect tliat title shall pass to the buyer upon actual physical receipt of the goods, then delivery takes place v:hen the buyer physically receives the goods. In other v/ords on a "delivered sale" if the buj-'er and the seller agree that title shall remain in the seller until such buyer physically receives the goods, "delivery" has not taken place until the buyer actually receives the goods. 37. Q,. Can a shipper, cooperative or grovrer's sales agent offer less-than- carlot quantities of apples through brokers at auction? A. Such' sellers may legally sell" at auction. 'The ceiling price is the same as the ceiling price for sales to intermediate sellers. Auction fees and brokerage must come out of (not be added to) the ceiling price for less-than-carlot sales to intermediate sellers, 38. Q. If decay exists in a package of apples, may the fruit be invoiced at the v.'eight markeH~on tlie package, or must an allowance be made on the invoice covering the amount of decay? A. The apples in this package must be sold on the basis of their pf^r pound ceiling price, derived from the net iveight marked on the pack- age, without regard to the condition or quality of the fruit, GFG 11/23/43 10 43 December 30, 1943 Prepared by the Fruit Program Committee of the Extension Service W.

TO PLANT OR NOT TO PLANT PEACHES This past season peaches were a "golden harvest," Six to nine dollars a bushel makes a few acres of peaches look like a gold mine. But looks can be deceiving. So if you're planning to plant peaches, let's con- sider a few facts and what they mean. The 1941 crop was 57% below the 1942 crop and 24^ below the ten year (1932-41) average. With the exception of Michigan, Pennsylvania, and New Jersey, which had fair crops, the crop in the eastern half of the United Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, Willard A. Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. -2- States was very short. The New Ent;land crop was a total failure. It is unusual for so nanyof the eatern peach sections to have crop failures in the same year. According to the 1940 United States Census, there were in the United States in 1939 47.1 million peach trees of bearing age and 21,7 mil- lion not of bearin;;; age. Assuming that l/3 as many trees not of bearing age as those of bearing age are required for normal replacements, there is an excess of 6 million young trees. In another 4 or 5 years, these should be at the peak of their production. This indicates a considerable increase in peach production with its consequent influence on price just as trees planted . in 1944 are coming into bearing. Therefore, prices in 1943 were far above normal because of un- usual circumstances. Normal prices will tend to decline due to increased production of young trees already planted and coming into bearing. However, the picture for the commercial grower in Massachusetts is good if he uses his knov/ledge and skill to best advantages The number of peach trees in Massachusetts, both bearing and nonbearing, is the lowest in many years. Locally grown peaches have always found a ready market at satisfactory prices » However, six or seven dollars a bushel cannot be ex- pected from locally grown peaches if the national crop is large-, On the other hand, the novice better follow the time honored advice to "make haste slowly," Just consider a few of the difficulties' 1. The orchard site is very important. Massachusetts is on about the north- ern limit of peach growing. Unless the peach orchard is vrell situated, frequent v/interkilling of buds v/ill make tlie orchard unprofitable, and killing of the trees may ruin it. All too frequently crops are lost even in favorably situated orchards. 2. Variety selection is important, A beautiful picture and glowing v/ords guarantee nothing, 3. Among the insects and diseases to be controlled are the following ser- ious one SI a. The oriental fruit moth, which is the chief cause of wormy peaches, has been in Massachusetts for many years. No ade- quate control has been vrorked out for tliis pest. b. The peach tree borer is a serious pest. A single borer can ruin a young tree before it reaches bearing age, &• The yellow-red virosis (X-disease) has come into Massachu- setts recently. This virus disease can be controlled by elim- inating all chokecherries in the vicinity of the peach orchard, but this is no small job. d. The plum curculio, vfhich also makes peaches wormy, is some- times controlled with arsenate of lead. However, peaches are very susceptible to injury by the arsenic in this material. 4. Peach orchards, except very small ones, require mechanical equipment for their care. Under war conditions this equipment is high priced and hard to get. 5. It costs money to bring an orchard into bearing, A crop failure or two at the wrong time may turn that gold mine into a millstone. -3- The experienced peach grower knows where to locate his orchard as regards site and soil. He knows varieties and what to look for in a new one. He has the equipment and knows how to use it. But most important of all, he has the "know how" for growrLg and handling peaches. The novice who has all tliis to learn had better "stop, look, and listen" to make sure that he gets onto the train and not onto the track. — J. S. Bailey CONTROL OF PEACH TREE BORERS Dr. Oliver I. Snapp, the originator of the eythylene dichloride treatment for the control of peach tree borers, has been looking for some- thing more safe and equally effective. He reported recently that propylene dichloride, even when l/4 to l/3 less is used, is as effective as ethylene dichloride and much safer. However, his experiments have not progressed to the point where he is recommending propylene dichloride for general use. — J. S. Bailey DAHGER IN HEAVY EARLY 17INTER PRUNING An apple grower told at a recent meeting that he had started to do a very drastic job of lowering the trees in an excessively tall orchard. Some of the trees had been slashed back to about half their former height, TJ'ords of caution from others at the meeting about heavy pruning before mid- vanter will probably set him thinking. The following is quoted from the October issue of "Food for Victory with King Apple," (University of Illinois)} "Experience in Illinois indicates that fall and v/inter pruning of apple and peach trees may result in serious tree-killing v;hen the pruning is followed by sub-z«ro temperatures. During the v/inter of 1935-36 a 30-acre block of peach trees pruned from December to February was killed to the ground by a Feburary sub-zero cold wave. The rest of the orchard, which was unpruned, was killed back to a height of about six feet. Durin.^ the severe v/inter of 1929-30 a block of '.wealthy and Duchess trees in the University orchard at Urbana, which had been pruned before the cold v/ave, was so heavily damaged that more than half the trees eventually died. The heavier the pruning, the greater is the hazard. Pruning wounds heal better when cuts are made in the spring. If it becomes necessary to prune during the winter because of labor shortage, it is suggested that stubs about a foot long be left on all cuts more than 2 inches in diameter. These stubs may thon be cut off in early spring v/hen the danger of sub-zero temperature is past. This will en- able the bremch to be taken out of the orchard during the winter." Similar observations v/ere made in Massachusetts after the severe winter of 1935-34. There is apparently much less danger from fall and early winter removal of weak, drooping branches or parts of branches, than from heavy cutting of vigorous branches. In a recent release to Connecticut growers under the heading, "Tall Trees are Expensive," H, A. Rollins says, "If you cannot reach the tops of your a^jple trees with a 20-foot ladder it is time to lower the tops by pruning, so that you can spray, thin and pick the apples more easily next year. -4- Growers are finding it very expensive t ) produce apples on the tall trees and almost impossible to get them picked with inexperienced labor. Some growers, in recent years, have lowered the tops of their tall trees by rather drastic pruning. Others are planning to do something about it this winter. To avoid v/inter injury, large cuts should be made in late T//inter after the danger of extremely low temperatures has passed. Unless cuts are made so that the main limbs will be partially shaded, sunscald on the tops of the branches may cause serious injury. If the tops are pruned heavily, the rest of the tree should have only a light pruning. Plan your pruning program navi before you forget how difficult it was to pick those apples from tall trees."

(The printing, at least, is good). 2)."U That the Common Barberry (Berberis vul^^aris L.) is one of the first plants brought over by the early English settlers for the purpose of providing a fruit from which jellies and jam could be made? This plant with its sour fruit makes an interestingly flavored jelly. Since its early in- troduction it has spread because of birds eating the berries and thus dis- seminating the seeds, until now it is found all over our pasture hillsides in the Northeast, This plant is frequently used as an ornamental in gardens, and in the fall of the year the sprays are much used in decorative arrange- ments. Of interest to fruit growers, however, is the fact that it was orig- inally introduced from Europe for its fruit. It has always been interest- ing to me that in a land which abounds v;^ith native fruits, the early set- tlers, because they did not know these fruits, made an effort to introduce some from the region v;ith v;hich they were familiar. Of the native fruits three are outstanding, - the blueberry, cranberry, and native strawberry, all of which soon offered stiff competition to a plant which was introduced for its jelly possibilities. — A, M. Davis That history records the finding of cranberries on Cape Cod as early as 1602? In 1638 an English naturalist visited this section and in making a record of New England "rarities" mentions "cranberries" which he stated "The Indians and English use much, boyling them with sugar for sauce, to eat with their meat". That the use of magnesium as a soil treatment may become as com- mon in some sections of the U. S, as the use of calcium, nitrogen, phosphor- us and potassiura? An application of one of the magnesium compounds appears to be very much needed on some iiassachusetts fanas. That ground limestone obtained under the AAA program maybe ap- plied to crop land, pasture, poultry ranges or commercial orchards? Ground limestone may be secured by farmers up to a tonnage not exceeding that de- termined by the total of the units on the farm, divided by 5, fi^jured to the nearest ton on the basis of farmyard delivery. If lime is taken at the rail- road siding, 20/j more material may be added. If taken at the lime manufact- uring plant, another 20;,o is added. That ceiling prices idll probably be established on all fresh fruits during 1944? OPA is planning to bring under control, well in ad- vance of next season's crops, all the remaining fresh fruits including sweet cherries, apricots, peaches, pears and plums. That certain gift packages of apples are exempt from price con- trol regulations? The provisions of an OPA release dated November 25, are as follows! "Apple growers and shippers v/ho package their apples in boxes with a net weight of not more than 26 pounds, with not more than 5 boxes sold at one time to one buyer, shipped by Express or parcels post, are not under price control with respect to such sales." -6- That a recent ainendiaent to the apple ceilintj order increases the ceilin,; in so-called sec mdary or rural markets? Under this araendment the ceilintj on apples delivered in less than car lots or less than trucklot quan- tities to secondary markets at a distance of 25 miles or more from primary markets is 18/ per box higher than the primary market ceiling. This in- crease of 18/ in ceiling price of apples delivered into these secondary mar- kets will, it is hoped, result in a more equitable distribution of current limited supplies, 3PHAY i.IATERIALS FOR 1944 LIUST BE OltPERED AIJU STOCKED EMLY One of the most important questions that confronts the farmer and victory gardener right nov/ is looking out for his supply of fungicides and insecticides for 1944, It is equally essential that retailers estimate their needs of these materials for the coming year, get their orders in and actu- ally stock up on those supplies at the earliest possible moment. If these matters are not attended to promptly, many of us are likely to find it im- possible next summer to obtain the right kinds of dusting and spraying ma- terials at the time they are most needed. In the past season, supplies of copper fungicides, mercury and nicotine dusts vrere short in many localities at the time they v;ere needed to combat such pests as cucumber and potato blights, cabbage maggot and plant lice on potatoes, tomatoes and a number of other vegetables and 'fruits. The officials of both the Agricultural Insecticide and Fungicide Association, a nation-wide organization of manufacturers and distributors, and the Tiar Food Administration warn us in no uncertain terms that the situation is likely to be even v/orse in 1944 due to increasing shortages of labor or manpower at manufacturing and distributing points, and to the critical container situation and tha limitations in transportation facilities. VHiile the present outlook for fungicide and insecticide supplies is fairly good for 1944 as regards allocation of rav/ materials for their man- ufacture, yet the Agricultural Insecticide and Fungicide Association issues the warning that, "Host important of all, the dii^ tributor s, dealers and con- sumers all must place their orders and take their deliveries earlier than ever before — to beat those manpower, container and shipping deficiencies. This applies particularly to copper compounds," The Yiar Food Administration recently sent out the following telegram directed to people over all the country: "\fer Food Administration urges farmers to help make the 1943-44 distribution of insecticides and fungicides fully effective by placing orders now and requesting early delivery, . . Because of transportation, labor and shortage difficulties it is necessary to keep insecticides and fungicides moving if manufacturers are to meet farmers' needs. . , Manufacturers have been taking in raw materials for next season production since September 1st and the finished insecticides are now building up in storage. . . Farmers ac- cepting insecticides and fungicides now should have no difficulty in storing them on their farms in a dry, floored, weather-proof building. , , Unless farmers cooperate with V/ar Food Administration by accepting supplies early Vire may encounter serious problaas." For the benefit of all concerned, it is hoped that farmers and gardeners, as v/ell as retailers, throughout Massachusetts heed these requests and i/arnings , and place their orders for and stock up with fungicides and insecticides just as early this fall as possible, — 0.

Armoniuiu suifate is beneficial as it increases soil acidity and releases Manganese which is fixh;d in the soil by too little acidity. Copper deficiency is indicated by small "cupped" terminal leaves, chlorosis, and dying and drcpning of the leaves. Axillary shoot grov/th is stimulated and shoot tips die. Application of a vrjak copper sulfate, eithar to the soil or as a spray, corrects this condition. (Proc. itoier. Soc . for Hort. Sci. 42, pages 74 and 79.) _j_ ^^ 2^^^^ THE YELLOV/-RED VIRQSI3 The "X-disease" of peaches is now acquiring a real name. It v/ill be known as the Yellow-Red Virosis, because it turns peach leaves yellow and choke- cherry leaves red. It vms discovered in Connecticut in 1933. It had doubt- less been present there and probably in Massachusetts before that time. It was discovered in the Iludsoii Valley in 1938 and is now pretty well spread over the northern part of the peach country. A recent bulletin of the Geneva Experiment Station reports the results of a study of the disease in that state. It is caused by a virus vihich is "an exceedingly minute infective principle not visible under the highest magnification of the microscope." The chokecherry is very susceptible, and the virus is supposed to be carried to the poach by some insect v/hose identity has not yet been discovered. It may pass from peach troo to peach tree, but less rapidly. It may also be transmitted by buds from diseased trees. Chokech^irry bushes must not bo allov/ed to grow v;ithin 500 feet of a peach orchard. Sodiujn chlorate and ammoniuin sulfamate vjoro the only ma- terials found satisfactory for killing chokecherries. Ho poach variety oscapod the disease vjhen inoculated with virus-infected tissue but possibly some var- ieties Jvre less susceptible than others. The common black cherry does not carry the disease.

Shaw -5- SEEU AIID lEAPJ) IN ilAIIE IIavin£; boen loaned to the Stato of Main'j for tvra wooks (Jan. 9-2^), the v;ritor tak^s this opportunity to r eport a few of his observations. The trip involved seven v/ell attond^^d fruit meetings, throe county agent confer- ences and numerous visits vdth individual growers. Nev/spaper accounts of heavy snowstorms this winter are not exaggerated. Snow plows, in some tov.'ns, have been taxed to the limit and many of them are laid up for repairs. Some telephone lines are dov/n, and certain orchards are so deeply buried that mid-winter mouse control measures are out of the question. Hardy Stocks. Cold winters have caused so much damage to apple trees in i.Iaine in yoars"pa'st that there is real interest in establishing orchards on one of the hardy stocks. The severity of Maine winters is shown by the fact that Baldwin trees on ordinary seedling stock will survive only tv:o or three years in the vicinity of Orono, But if grafted in the branches of a Hibernal or Virginia Crab tree even the tender Baldwin will survive for many years. The method of establishing an orchard on a hardy stock is briefly thisj An ordinary seedling -v/hip is budded to Virginia Crab or Hibernal in the nursery and after growing a year or t\io is transplanted to the orchard and developed as a leader tj'pe tree. T/7ide angled branches develop naturally on these var- ieties. V/hen the framev/ork is v/ell established the brandies and "leader" are either budded or vihip grafted to the desired variety, the buds or scions being placed on the branches as far out as 18 inches from the trunk. The resulting tree is thus a throe-story affair, having a seedling root. Hibernal or Virginia Crab trunk and main branches, and a top of the desired variety. This kind of tree looks especially promising since much of the winter injury in ordinary trees occurs in the trunk and crotches. A nursery pool under the supervision of State Horticulturist Stanley L. Painter, makes it easier for growers to ob- tain these custom made trees. Leaf Scorch (Magnesium Deficiency). As in Massachusetts, leaf scorch \_caused by magnesium deficiencyX presents a real problem in some Maine orchards, The leaf symptoms include yellowing betv/een the veins, and later, a dropping of the older leaves on the terminal growth. Tests have been conducted in a Maine orchard for a number of years, using a v;ide variety of materials, V^Tiere potash was used, leaf scorch was more apparent than before, V/ithin the last two or three years the effectiveness of magnesium sulfate (Epsom Salts) has been clearly demonstrated. At present, three spray applications, using 20 lbs. in 100 gals., are recommended in magnesium deficient orchards, the first around Calyx period and the other two at ten-day intervals. Northern Spy and Golden Delicious. Certain orchard locations seem very well adapted to the grov;ing of Northern ^pies . At the fruit meetings in Buck- field and T(/ilton large Spies of unusually (,ood color and quality (from the Conant and Weeks orchards) v/ere distributed. On the basis of these saiaples it appears that this old variety is very much at home in the Pine Tree State. The Golden Delicious varies vddely in different orchards. From the Y/allingford orchard in Auburn we sav/ some exceptionally fine Golden Delicious. These ap- ples vrere the result of a good soil and good management, including thinning. In other orchards this variety is snail in size and of mediocre quality, due in part, perhaps, to a lack of thimiing. -6- Orchard Crov.'ding. Vjliile the snowisas too deep to walk through any of 'the o rcli'a'r'cf s~,~th" "prob 1 e m of crowding appears to be as widespread as it is in Massachusetts, Many of the orchards have just about reached the age where something r.iust be done about it. Maine growers seem as much inclined as \.'e to delay the removal of fillers "one more year." At most of the meet- ings this point was brought out: Yi/hen a grov;er finds the branches brushing the sprayer as he drives through, he should begin a drastic cutting back of the temporary trees, or the trees in every other diagonal row, V/hen this practice no longer allov/s ample space for efficient spraying, the temporary trees should be removed entirely. And if the removal of filler trees is al- ready ovt^rdue, as is so evident in many New England orchards, the sooner we remove every other diagonal rov/, the better. A bulldozer is an ideal tool for this purpose, Appl^ Scab Control. In general, Maine growers seem to have an easier time in "coivfcFo 1 1 i n g'Tcab' Ifh an vje have in Massachusetts, An exception to this rule is found in counties near the coast where tr^jos seom to dry off lese readily after a rain. Growers farth'^r inland and at higher elevations find it possiblo to control scab, in some seasons, with only two or three sprays. On*^ groi/er is actually reported to have qualified for th*^ 90^i Clean Apple Club on a crop which receiv«:;d only tvifo sprays. There is considerable intf;rest in dusting both for the control of scab and apple ins^;cts. One insect, known as the mealy bug is causing consid-;rable damage in Maine orchards. Thus far, our Massachusetts grov;ers have not had to v;orry about this particular pest. Deep Snow Favors Mice. There is some cause for worry about possible mouse damage unTeTTh" "sirow'^in some of the Maine orchards. T^vo very heavy sno\7stormG have cor.f letdly covered all mouse runs, thus preventing growers from doing effective mid-v/inter baiting. Unfortunately, quite a number of orchards had not been baited when the first heavy snow came in rfovember. As the snow thav/s, grovrers are advised to pack it dovm around the trunks of trees as one means of checking mouse damage. "A GOOD PRODUCT IS ITS BEST ADVERTISEIvJENT-" In a release from the National Apple Institute under this heading John Chandler, Executive Secretary,, says in part, " . , , Of recent years, the economic factor has worked against good apples doing their own advertis- ing. Back in the tvrenties, v;hen apple prices returned a good living to grow- ers and when there were no ceilings, the better packs of apples resulted in handsome returns to the growers for the extra expense incurred. Consequently apples were their ovm best advertisement. Unfortunately, during the dark decade of the thirties wlien most consiuners were buying the cheapest food avail- able, the premium for fine packs practically disappeared, Du.ring the last twelve years on] y enough grading and packing hae bcjn done to move the apples. Many good Eastern packs disappeared entirely. Although growers far from i.iarket maintained the high standards vriiich paid out during tho twenties; this was done to retain an outlet for their apples rather than \;.-j.tii any hope of com- mensurate returns, since they v;ere often obligt.d to accept prices disastrous to them. "So I feel that the long depresiion, rather than the attitude of apple growers has been responsible for so many poor apples appearing in the markets with the consequent falling off of demand and the further depression of prices. By the same token most apple jrov/ers have had their pride in, and enthusiasm for, quality packs pretty well atrophied over a period of many years, during which better packs have meant only added expense. Since the present economic outlook indicatee the possibility of profitable years aJiead for apple grov/ers, nov/ is the time to stress placing attractivf^ appl«?s before the public as the best possible advertisement for our products. Good packs of apples, plus the promotional machinery brought into existencfj through the depression years, should restore apple production to a sound and profit- able business," TIIE SIGNIFICAIICE OF SOIL ACIDITY IN TliE ORCHARD For many yiars farmers have considered the various fruit crops as being either very tolerant of acidity or as actually preferring a strongly acid soil. An occasional orchard is found growing on a soil which is much too acid for the grov^th of clover and other legumes. But vie should not lose sight of the fact that cover crops in general have a shallower root system than apple trees and are therefore influenced to a greater extent by the acidity and availability of mineral elements in the surface layer. Cur Massachusetts soils are generally more acid in the surface soil than they are in the subsoil. This is due to at least four causes. (1) Crop removal tends to take from the soil calcium, magnesium and other basic ma- terials. (2) Leaching tends to carry these basic materials into the subsoil or they may be removed in the drainage water. (3) Erosion carries some of these materials to lower levels. (4) Heavy applications of sulfur have great- ly acidified some of our orchard soils. This latter factor alone has actually made the soil ben^jath some of our trees so .acid that nothing but moss will grow at the present tine. All flowering plants, including the various grasses, have bf;en completely excluded because of the acidifying action of sulfur. Under th^jso conditions, one may wonder how an apple tree can continue to live, to say nothing about producing crops of fruit. This mystery is explained by the fact that the roots of an apple tree under good growing conditions range deeply into tho subsoil and also far beyond the spread of the branches where soil conditions may bo much more favorable. There is a definite relationship between the availability of the var- ioui mineral elen^'nts needed by a growing plant and the acidity of the soil. If the soil is too acid nitrifying bacteria become inactive and as a result the decomposition of organic matter becomes so slow as to affect the supply of nitrates. Furthermore, if the soil is either too acid or too alkaline phosphorus is believed to be locked up in unavailable forms. V/e may there- fore think of lime as a soil conditioner. As we bring about the desired de- gree of acidity we create conditions which favor the availability of minerals needed for plant growth. In addition, tho lime which we apply contains calcium and laagnesium both of vihich are essential in plant development. Every fruit grower should determine tho acidity of the soil in his various blocks to determine whether or not lime is needed, and if so, how much -8- should be applied. Unless the soil is obviously very acid we ought not to apply lime vfithout first making a soil test. In grandfather's day, folks took sulfur and molasses in the spring on the assuraption that it would do no ham and it might do some good. Some folks lime the soil on the same basis, a little now and then as a matter of insurance. In the absence of a soil test, much can be learned about the need for lime by studying the natural growth of weeds, grasses, etc. If orchard grass grows waist high, we needn't worry about soil acidity. And if clovers thrive, there is reason to believe that conditions are reasonably favorable for the trees. But if the cover crop consists of a discouraged grovith of cinquefoil, sorrel, dewberries, poverty grass, and certain sedges, there is ev^ry reason to believe that the soil is very acid. Ordinary grasses fail to grov/ before these miscellaneous acid tolerant plants occupy the soil. An occasional ap- plication of lime is of great benefit in maintaining a good cover- crop which exerts an indirect effect upon the troo. The continued use of sulfur in the • control of apple scab has more or less completely changed the type of cover crop in many of our orchards. Tliis is to be expected since 500 pounds of sul- fur mixed with the surface six inches on an acre of fine, sandy ioam tends to lov/er the acidity rating by about one-half a pH unit. In other words, a soil rating pH 6 might actually become pH 5.5 after applying a quarter of a ton of sulfur per acre. It is interesting to note that many of our best orchards are on soils ranging betv/een 5.5 and 6.5, One other factor in connection with soil acidity should also be con- sidered. Magnesium deficiency is becoming a serious problem, particularly in eastern Massachusetts. Many such orchards are on Gloucester or Merrimac soils which are naturally low in magnesium. Such soils are also inclined t'l be strongly acid. As a matter of good orchard management, soils of this kind should be limed, using a high magnesium or dol :)mitic limestone. This will aoc mplish two purposes. It will tend t'l c 'nditi on the s 'il by reducing acidity, and it may ultimat^ily supply s me of the magnesium nw lacking in the soil. But if the deficiency is severe, a more readily available form of magnesium, such as magnesiuiii sulphate -tr epsom salts, should als'i be ap- plied. An application of high magnesium limestone seems to be long overdue on the average fruit farm. In view of the fact that 50 gears may have elapsed since some of our fields received an application of lime, the 50th Anniversary of the Massachusetts Fruit Qrowers ' Association is an appropriate time to satis- fy a long felt need. To clear up any misunderstanding concerning the relation of the pH num- bers to actual soil acidity the following figures are presented: 7 represents a neutral soil; 6,5 slightly acid; 6.0 moderately acid; 5.5 medium acid; 5,0 strongly acid; 4«5 very strongly acid; and 4.0 extremely acid. A soil which rates pH 4 is ten times as acid as one v;hich rates 5, and one hundred times as acid as one vihich rates 6. Practically all of our Massachusetts soils fall within the range of pH 4.5 to pH 6.5.

Sterling, Illinois personally applied 268,000 gallons of spray material on his orchard in 1943. His only assistant was the tractor driver . He used a sprayer with a 400 gallon tank and did all the spraying from a ttwer. ^ .,.,•, f J b — L, Southwiok HEARD IN I.IAINE At the annual meeting of the Maine Pomological Society the question came up concerning what variety to plant to prolong the Mcintosh season. Many Maine growers are interested in a hardy winter apple to take the place of the once widely planted Baldwin. Some hardy varieties produced in the Middle West and some unnamed seedlings from the breeding work in Maine and elsewhere may find a place. Bat one of the most interesting comments to come out of the discussion was made by County Agent Lovejoy who operates a sizeable orchard venture of his own. He argued that instead of seeking a brand new variety for the late market, Maine growers should first test extensively a variety that has already proven itself. This variety is Golden Delicious. Mr. Love- joy contends, on the basis of his own experience, that the Golden Delicious can be grown successfully and profitably in Maine. Furthermore, a man who has marketed many Maine apples in New York was present and he stated that Maine grown Golden Delicious have topped the New York market. He felt strong- ly that the market can absorb a greatly expanded production of well-grown Golden Delicious apples and urged that grovrers who have the right soil and growing conditions might well increase their plantings of this variety. — L, Southwick APPLE AND PEAR UTILIZATION The Crop Reporting Board of the U.S.D.A., Bureau of Agricultural Economics, reports that during the period 1934 to 1942 about two-thirds of the country's commercial apple crop v;as sold as fresh fruit. Considering the 1942 crop, 78,246,000 bushels were sold as fresh fruit; 6,541,000 bush- els were used in farm households; and 35,102,000 bushels 'were manufactured into products as follows: canned apples - 11,426,000 bushels; dried apples - 7,376,000 bushels; vinegar, cider, apple juice and other products - 16,300,000 bushels. New York, Pennsylvania and Washington are the most important states in the canning of apples, accounting for 57 percent of the apples canned in 1942, About 90 percent of the nation's production of dried apples comes from California, 1/Yashington, and New York. The three leading states in the man- ufacture of vinegar, cider and apple juice are New York, Pennsylvania and Virginia. Of the 1942 pear crop, 15,584,000 bushels were sold for fresh use; 10,797,000 bushels were canned; 3,244,000 bushels went for farm household use; and 627,000 bushels were dried. — L Southwick -3- ^MfJ^Z^^ That a new insecticide, known as DDT, is found to be extremely and instantaneously toxic to many insects? This material, the full name of which is diohloro-diphenyl-tri-chloroethane, was first synthesized 70 years B-go V-y ^ German chemist. It was not until 1959, however, that it was patent- ed by a Swiss firm as an insecticide. DDT is very toxic against flies, mosquitoes, bedbugs, and body lice, and in powder form may be dusted on human skin without harm. One application of the pov;der to the walls of a room makes the room a death chamber for flies for three months. At pres- ent the entire output of this nev/ material is being used by the Army, Look- ing ahead, one caji foresee a new era of insect control in the orchards of America, That the designation "Mailing," applied to dwarf apple trees, is de- rived from the East Mailing Research Station in England, v/here the more common root stock materials for the apple were freed from mixtures, standardized and designated by number as Mailing 1, Mailing 2, etc.? Most of these dwarf- ing stocks are relatively old, as plants go, although their standardization and introduction by number has taken place within the last few years, That several of the so-called "Hailing" stocks have been known for many years under various names, including Doucin and English Paradise? Mailing 1, for example, was known as Broad Leaf English Paradise, Mailing 2 as English Paradise, Mailing 4 as Dutch Doucin, Mailing 5 as Improved Doucin, etc. Mailing 9 v;as selected as a chance seedling in France about 1879. That a sodium salt of dinitro-cresol at concentrations of ,1 to ,2^, applied at blossoming time, offers considerable promise as a means of reduc- ing the set of fruit on certain biennial bearing varieties? This material v/ill destroy a blossom that has been open for oniy a fev/ hours but does not seem to prevent fruit setting if a blossom has been open for a day or more. Thus it is possible by proper timing of the spray to destroy 5 of the 6 blossoms on the spur. It is a well knoi-m fact that the center flower tends to open a day or so before the lateral flowers, ^ince this practice is still in the experimental stage, it is recommended that trials be limited to cer- tain varieties, including Transparent, Early Mcintosh, Duchess, suid Vfealthy, in which the results have been quite gratifying. That more than 10 million bushels of pears v/ere canned in the United States in 1942? Pear production in the United States varies less from year to year than apple production. The yield of pears in the United States, dur- ing the nine years from 1934 to 1942, varied from 25,943,000 bushels in 1935 to 31,704,000 bushels in 1938. -4- That tho supply of nitrogenous fertilizers available to farmers this season v/ill be about 35^.0 greater than in any previous year? There v/ill, therefore, be more nitrogen in mixed fertilizers and for direct application as top and side dressings. This increased supply will be equivalent to about 850,000 tons of annonium sulfate. Ammonium nitrate is at the present tine, and may continue to be, a lov; cost source of nitrogen for direct application. More than 200-,000 tons of ammonium nitrate will go into mixed fertilizers in 1944. That a probe for hot haymows is now available? This piece of equip- ment consists of a pipe with a thermometer inserted in a pointed nose. A reading as high as 150*^- F. indicates danger from spontaneous combustion. If a similar gadget were available for investigating the subsoils in some of our orchards, we venture the opinion that the cause of poor yields would be apparent. Unlike haymows, some of them would probably register "not so hot." That an individual in Stevirardstown, Pa. is interested in buying apple logs, for which he pays $40 a thousand board feet? The logs must be green, not dead or wormy, and must measure 13 inches or over in diameter at the small end, and may be as short as 3 feet. For further information, consult R. B. Parmenter, Extension Forester, M.S.C. That the ability of a rye plant to withstand deep freezing of the soil may be due in part to the elasticity of the roots? Unlike the roots of many other plants,, including strawberries, a rye root may stretcli an inch or more without damage. Thus the rye plant possesses at least two advantages as a cover crop, namely, its ability to grow in late fall and early spring, when the temperature is too low for most other plants, and the ability of its roots to withstand stretching. That thavdng of the soil in spring takes place both from above and be- low? In view of the fact that the soil just below the frozen layer is con- siderably above the freezing point, thawing from below may be relatively rapid. Thus a deeply frozen soil is ready for tillage much oarlior in the spring than if all the thawing were to take place from above. That one of the most efficient packers of apples in the Wenatchee district in Yfashington is totally blind? At first she packed about 50 boxes per day although now she is able to pack more than 90. That the interval between full bloom and fruit maturity is fairly con- stant from year to year for a given variety? The apple is more consistant in this respect than other fruits which have been studied. There appears to be a greater variation in the bloom-maturity interval in early maturing than in late maturing varieties. H. B. Tukey of the Geneva, N.Y. Experiment Sta- tion suggests that growers, by keeping records, may obtain information v;hich should be useful in planning their orchard operations. M. H. Haller of the U.S.D.A, in a study of four varieties, T/illiams, Jonathan, Grimes Golden, and Yellow Newtov/n, found that regardless of locality and seasonal variation, the number of days from bloom to maturity is quite constant. VJ'ith the above var- ieties, he suggests that harvest should not begin until at least 70, 130, 135, and 150 days, respectively, after full bloom. The optimum maturity stage v/ould be somev/hat later. -5- That sawdust is proving to be a desirable mulching material for blue- berries? In a study of mulching materials in Georgia, where temperatures are high and there is frequently a deficiency of soil moisture, sawdust because of its ability to reduce evaporation and runoff, v;as by far the best mulch material tested. Being cheap and easily available, it is recomiaended for mulching blueberries in the Southeast. Looser materials, such as straw and oak leaves, were better than clean cultivation but not so effective as sav;- dust . That strawberries sometimes yield better under a spaced runner system than in a matted rovj? In YiTest Virginia, five varieties, Blakemore, Catskill, Culver, Fairfax, and Howard 17, were spaced 8 inches apart. In each case the spaced plants outyielded the same varieties in matted ro\/s . Under Massachu- setts conditions, we sometimes get a better yield v;ith certain strong grov/ing varieties like Catskill, although the Howard 17 may do almost as well in a matted row. That there are at least four reasons why some grov/ers have failed to get satisfactory results with sprays applied for controlling ilclntosh drop? Among these reasons are: (l) Faulty coverage. It takes much more material and a better distribution to wet the stem of each apple than is applied in the average spray during the spraying season. (2) Temperature too low. The spray is much less effective if applied v;hen the temperature is 60 degrees than at 75 degrees. (3) Faulty timing. Since the spray is effective on Mcintosh for only 9 or 10 days at best, the effect in some cases wears off before the apples are due to drop. In otlier cases, the apples may begin to drop before the material tecomes effective. This latter interval is about two days. (4) The Mcintosh variety is less easily influenced than certain other varieties. VJ'illiams, Duc?ie5S, Delicious, and certain other varieties are apparently held on the tree more easily than Mcintosh. That more than 7,000 varieties of apples have been named and intro- duced? As late as 1900, 340 varieties were recommended, and nurseries v^ere selling at least 1400 kinds. The variety list has rather steadily narrov/ed down until today only about 30 varieties are of commercial importance. Con- sidering the 1942 and 1943 production, Delicious led all other varieties in importance, followed in order by Vfinesap and Mcintosh, — L. Southwick CHAIIGES IN 1944 APPLE SPRAY CHART V/e have been informed by the printer that the 1944 Apple Spray Charts have been shipped. They will be distributed to county agents and growers immediately upon their arrival. The chart this year has been printed on two sheets so that the notes can be referred to more conveniently. In general, changes in the Spray Chart this year are of a minor nature. It vdll be noted that v;-ettable sulfur may be used in Emergency Spray A instead of lime sulfur provided that this spray is applied merely as a protective cover. Line sul- fur must be used if scab spots are to be burned out. A revised Spray and Dust Chart for Peaches is expected to be available for distribution presently, __^^ ^^ ^^^^^^^ -6- BLUEBERRY VARIETIES During the past tv;o or three years there has been an increasing interest in the planting of cultivated blueberries. As with other fruits, a careful selection of sites, soils, and varieties is highly important in making a good start. Better blueberry varieties are being introduced so rapidly that in a very few years much better varieties than those in our present list will be available. Since this will probably be just as true 3, 5, 10, or 100 years from now, the grower who always \vaits for those better varieties will probably die waiting. "Time is now," so let us make the best of v>rhat we have. Since blueberry varieties vary from partly to totally self unfruit- ful, tv;o varieties are needed for cross pollination. The coirunercial list is short, - Pioneer, Rubel, and \Tarehain. To these might be added Gabot where an early variety is desired for roadside stand or local trade. Pioneer is a midseason variety, ripening from middle to late July or early August. The berries are large, fine flavored, attractive, and good keepers, Tlie bush is of medium height and fine appearance for ornamental planting. Unfortunately the yield is lov/ and it is difficult to propagate and prune. It is being rapidly replaced in other sections and will probably be replaced in Massachusetts as soon as a better midseason variety appears, Rubel is a late variety, ripening a few days after pioneer. It is a good producer. The berries are only fair in size, but their color and quality are good and they ship well. The bush is tall, upright, well shaped, vigorous, and easy to propagate and prune. This is one of the best varieties for the home gardener because it will withstand adverse conditions as v^ell as any and better than most other varieties, y/areham is an excellent late season variety, ripening a week after Rubel"]! The bush is vigorous, upright-spreading, easy to propagate and prune, and yields heavily. The berries develop good size throughout the season and have a highly aromatic, wild flavor v/hich is v;ell liked by most and highly pleasing to some. Although it starts v/ith Rubel, it ripens about 15^ of its crop after all other varieties are through. Unfortunately, it is dark in color and, therefore, not so attractive as other varieties and cracks badly following rains, Cabot is an early variety, ripening a few days to a vieek before Pioneer, The berries are largo and ship well but are rather flat in flavor. The plants are low and spreading and not so vigorous as Rubel, but yields are good. They are hard to propagate, costly to prune, and very susceptible to Phomopsis gall, a trouble v/hich looks much like crown gall. Other varieties which are recoLuiended for trial only are; Stanley is a promising midseason variety. The fruit is large, handsome, and excellent in flavor. The bush is upright, fairly vigorous, productive, -7- and easy to propagate and prune, but doesn't sprout so freely from the base as could be desired. It may be a suitable replacement for Pioneer. Jersey, which ripens with Rubel, looks very promising. The bush is very vigorous, upright, productive, and easy to propagate and prune, but does not sprout from the base so freely as is desirable. The berries are long sterimed, making for easy picking, large sized, very attractive, and keep and ship v/ell. The flavor is excellent if the berries are v;ell ■ ripened, otherviise they are sour. Since the berries turn blue a couple of days before they are ripe, it is very difficult at times to keep pick- ers from picking the underripe, very sour fruit. Pemberton is a very promising nev/ variety which ripens with Rubel. The bush is upright, very vigorous, productive and winter hardy. The fruit is unusually large, attractive, and fine flavored. It is easy to prune and is said to be easy to propagate. It's worst faults are a large v/atery scar where the stem separates and the tendency for a little piece of skin to tear off v;ith the stem. This leaves a place for molds to enter and start decay if the berries are not used within a fevif days, Atlantic and Burlington, tvio other nev/ varieties, have not yet been fruited at the Massachusetts Experim'^nt Station, but information available indicates they are v/orthy of trial, Dixi, although introduced several years ago, has not been tried ex- tensively enough yet to warrant any very definite opinions about it. The berries are very large, attractive, fine flavored, and ripen late. It is worthy of trial, — J. 3. Bailey IvIAIIURE FOR CULTIVATED BLUEBERRIES Dr. F. V. Coville, the father of blueberry culture, in his early greenhouse experiments \vith blueberries found that manure was so very toxic, in fact killed some of the plants, that he never carried the 'ixperiments into the fi'jld. Ilis repeated warnings against the use of manure were heeded for 20 or more years. Then a few grov/ers of blueberries because they wore more venturesome, or hadn't heard of Dr. Coville 's v/arning, tried manure in the field with apparently good results. For this reason, an experiment was started at Amherst in 1941 to compare three manures, cow, horse, and poultry, on cultivated blueberries. Horse manure v/as applied at the rate of 10 tons per acre, the first year, and 20 tons per acre the next two. The other two manures v/ere applied at such rates as to give approximately the same amount of nitrogen as in the horse manure. It is noteworthy that the blueberry plants have thrived and pro.» duced heavily under this treatment with no signs of the toxicity reported by Dr. Coville. The choice of a manure seems to be immaterial as all gave equally good results. — J. S. Bailey 1 ^-^ a T) 03 1 U -d 1 (B o X!

On the bark of dormant trees injury is apparently due to the penetration of the oil through the outer bark to the caMbiuir.. Under favorable conditions the reoomi;iended Eimount of oil in a spray will evaoorute or dry before it penetrates to the living cells. Howe-ver, if mere than a safe amount is applied^ or the rate of evaporation is decreased by cold, or by high humidity, the oil may have time to penetrate the oaiabium before it dries.

If the emulsion freezes before it dries, the oil separates and collects in larger drops which do not dry as rapidly as the smaller drops dispersed through the emulsion. There- fore, oil sprays should be applied when the weather is clear and drying may be reasonably expected in a few hours. Oil injury frequently develops first and more seriously on the small twigs v/here the bark is thin. Here the, cam- bium is less protected and the living cells are nearer the surface. — 17. D. YJhitcomb PEACH CROP PROSPECTS FOR 1944 If the College peach orchard can be taken as a good indicator, the prospects for a full crop this summer is very bright. None of even the most tender varieties, such as Elberta, Hale, Goldeneast, and Halehaven, has lost over 35 percent of its buds and most have ].ost less than 25 percent. The more hardy varieties such as Charapion, liarigold, and Oriols have lost only a fev! buds.. Varieties like Champion, v>rhich set fruit buds very poorly, us- ually average 10 buds per foot of shoot. Ordinarily a tree should not be allov'/ed to bear more than 2 fruits per foot. Therefore, 60 percent of the buds can be lost and still have left tv'vice as many as should be allovred to develop into fruits. Varieties which set fruit buds very freely, 30-40 per foot, such as Cumberland or the old Greensboro, can lose a higher percentage and still have enough left for a full crop, — J. S. Bailey CAN Y/E THIN THE 1944 APPLE CROP? Probably few fruit growers do as much thinning as they should. This year will present an especially difficult situation. Several Experiment Sta- tions have studied the possibilities of applying a caustic spray at blooming time to control the set of fruit. Vie have in preparation a brief summary of the results of these experiments. It is a little early to advise the general use of these blossom sprays but they show promise. Me expect to make some trials next sumiaer. If any grower wants to try them in an experimental way we are glad to offer assistance and advice, — J. K. Shaw (The Extension Service is in position to cooperate with at least five Massa- chusetts apple growers interested in testing the material mentioned above. Any reader of Fruit Notes interested in mapping out a test in, his own orchard, with the idea of checking results, is invited to drop a line to V/. H. Thies, II.S.C, Ai'iherst, Mass.) HELP.' J . - Two eastern Massachusetts apple growers are looking Ibr orchard foreman. One of these vacancies is in a largf" orchard and the other in a medium sized orchard. Both appear to be good opportunities for experienced men. ^jnother apple grower is interested in buying a good orchard of at least 500 bearing trees. Detail.s concerning these three inquiries may be obtained as indicated in the paragraph above. -3- /m That the importation of dried fi^js into the UnitRd States has dwindled from a high of 20,300 tons in 1925 to only 700 tons in 1940? From 4-5 to lb% of the imported figs formerly came from Turkey. The state of California shipped its first carload of dried figs to eastern markets in 1389. During the ensuing 50 years production has increased to 32,800 tons of dried figs and 19,000 of fresh fruit frorii a bearing acreage of 34,82G. That about 3,000,000 lbs. of apple syrup was made from the 1942 apple crop? 100 lbs. of apples make approximately a gallon of apple syrup weighing 11-g- lbs. At IG/ a lb. for syrup, the processor should be able to pay about 60;^ per 100 lbs. for apples. The largest single use of syrup is in the to- bacco industry where this syrup is being used in place of glycerin. That about 20,000,000 Victory Gardens were planted in 1943? The goal of 18,000,000 v/as exceeded by 2,000,000. In these 20,000,000 gardens, 8,000,000 tons of food v/ere produced, viforth conservatively half a billion dollars. Yet probably a third of the Victory Gardeners were rank beginners. The goal for 1944 is 22,000,000 Victory Gardens, 6,000,000 on farms and 16,000,000 in towns and cities. These gardens should be laade to produce 10,000,000 tons of food. That a shorter storage life of horiaone sprayed apples is due not to the use, but to the misuse, of this material? If the sprayed fruit is harvested during its normal maturity range over a period of 10 days to two weeks from the time of application, the storage quality of the crop is not materially lessened. It is only when the grov.-er elects to permit his hormone sprayed fruit to hang on the trees to acquire additional size that increased ripening and impairment of storage quality will result from the use of the hormone spray. That apples left loosely stacked under the trees over night may be cooler by morning than if placed in a crc(v;-ded storage room? Fruit picked in the afternoon is ordinarily hotter than if picked in the morning. For this reason, there is a decided advantage in bringing fruit to the cold storage during the morning hours, only. That top grafting of a single branch provides an effective v^ay of solv- ing the cross pollination problem? To provide a showy permanent bouquet of the pollinating variety a prominent limb vfell up in the tree and on the sunny side should be selected for grafting. Growers sometimes make the mistake of selecting an insignificant, low limb for this purpose. That the farms of Georgia derive an estimated annual income of betv;een ^800,000 and ^.2, 000, 000 from pecans? If we consider the nearly 2,000,000 trees' of bearing age, the yield per tree is disappointingly low. -4- That lack of crop due to insufficient pollination or to a poor spray program are two reasons why many apple trees grow too tall? By the time these shortcomings have been corrected, branches which would otherwise bend down- ward, are too stiff to be influenced to any extent. Other reasons for tall trees are orchard crovuding and the development of two or more leaders. That a Quad spray nozzle with 5/64th inch disc opening will deliver about 6 3/4 gallons at 300 lbs. pressure and 8 l/S gallons per minute at 400 lbs. pressure? The spray drive, or distance the mist \dll carry, is stepped up from 15 to 17 feet by increasing the pressure from 300 to 400 lbs. Added spray drive helps to provide coverage on otherwise poorly covered top branches. That the civilian population of the United States consumed about 75^0 of our total food supply last year? In reality the civilian supply is slightly higher than 75%, although for practical purposes the total food supply may be divided as follows: civilians, 75^o} our armed forces, 13^^; our allies, lO^j, and our territories and neighbors, including Porto Rice, Hav/aiian Islands and That a bushel of apples sold in Ilichigan last fall for 4-325? This was the svireepstake bushel at the apple shoi'/, a bushel of liclntosh grovm by Homer Waring, and ii/as auctioned to the highest bidder, the money being used for charit- able purposes. That our first knowledge of the plow, as used by man, comes from wall paintings in the tombs of Egyptian nobl»)s of 3,000 years ago? The plowman is shovm at work in a field with a plow rnade of a forked tree, one branch left long and attached to the ox yoke, the other cut short and pointed, to be dragged through the soil, and the butt of the tree was shaped into a handle. The Greeks used plows of a similar type^ to which they added a metal point. The points for this primitive type of plow, made of a forked tree, were still made in Connecti- cut as late as 1923 for shipment to the backwoods in South America. That almost 17,000 food stores distribute fruits and vegetables to Nev\r York City customers? Of this number, independent grocery stores number about one-third, chain grocery stores about one-tenth, and meat markets only 3jo. The weekly sales of fruits and vegetables averaged in chain stores from 12 to 14^^ of all sales and they handled from 14 to 17^j of the total fruit tonnage. That the term "bearing age fruit trees" is very often a misnomer? T/Yriting in the Rural New Yorker, II, B. Tukey says, "There is nothing wrong with the idea of bearing age trees, \j7ien trees are well grown in a nursery for this purpose, are transplanted in the nursery once or twice to develop a compact root system, and v/hen a first class article is delivered, there is much to be said for the bearing age tree. The difficulty lies in the fact that so many bearing age trees are nothing more than left overs from seasons when the demand for nursery stock was not high. Such trees may have been neglected in the row, may have suffered foliage injury and borer attack} and may have other- ivise been subjected to mistreatment. Vflien such trees are dug and delivered as bearing age trees the planter really gets an inferior product and is inclined to be disgusted, not only with bearing age trees, but v>rith the nurseryraan who supplies them," -5- That prunes, steamed before dehydration, produce a dried prune very similar to the fresh prune in color? These new prunes have the pink to red skin color of the fresh fruit and the flesh is a golden yellow. The steamed fruit dries much more quickly than that treated in the usual manner, and after drying it cooks quickly. It is believed that the new product, if produced commercially, will make new friends for the already popular dried prune. That the number of days between bloom and fruit maturity for a given variety is remarkably similar from year to year? The Geneva New York Experi- ment Station reports the following time intervals for several fruits j Early Harvest apple, 77 days; Oldenburg, 98 days; Uclntosh, 127 days; and Rhode Island Greening, 135 days; Montmorency cherry, 62 days, Bartlett pear, 121 days, and Elberta peach, 128 days. That Vitamin C is being extracted from green vralnut hulls? These hulls have 20 tines the vitamin C potency of orange juice. This extract is used for fortifying food products. Incidentally, Vitamin C is now being made syntheti- cally and can be sold for about i^l per ounce. That the average prices received by farmers for fruits of various kinds in 1943 were just about double those received in 1941? The average index mem- bers for the past four years are as follov;s: 1400 - 73; 1941 -. 85; 1942 - 114; and 1943 - 179. For the first month of 1944 the index number was 204, That the War Food Administration will establish support prices on cer- tain fruits in order to encourage the utilization of prospective 1944 supplies? These support prices will apply to producers and processors of peaches and pears for canning and for the following dried fruits; Apples, apricots, clingstone and freestone peaches, pears, prunes and raisins. That a decided shift from apples to nut crops has occurred in Oregon during the past few years? The apple acreage declined between 1910 and 1943 from 73,000 to 15,300 acres. During this time the walnut acreage jumped from 7,500 to 24,100 acres while filberts increased from 100 acres to 15,200 acres. Cherries increased during that period from 8,800 acres to 15,200 acres. That the total supply of processed foods available in 1943 was 321,000,000 standard cases, a decrease of 38,900,000 cases from the 1942 total of 360,700,000? A standard case of fruit contains 24 No. 2^- cans each holding approximately a quart. Production of processed canned fruits decreased 16,800,000 cases in 1943, the total supply being 41,400,000 cases compared to 58,200,000 in 1942, IN TODAY'S MAIL - A letter has just been received from the district manager representing the manufacturer of one of the commonly used orchard sprayers asking that v/e refer to him, for prompt attention, any case in which a grower is having difficulty with that particular make of sprayer. He says, "If you know of any service problems of any particular grower I wish you v;ould tell me about it. Vlhenever you have done this in years past it has been a service to the grower and to myself." This is too good an offer to pase up. Regard- less of the make of sprayer, it should be put in first class working order be- fore the beginning of the spraying season. -6- ORCHARD SOIL TILIAGE IN ITB7 BNGLAIJD Fifty years ago, plowing and continued cultivation of apple orchard soils in Nev/ England v/ere fairly commoji practices. Today the Sod-Mulch system, which is subject to iTieiny modifications, has been adopted by practically all of our commercial grovrers. The latter system tends to encourage good yields of well colored fruit. It also facilitates the penetration of rainfall and thus prevents, to a large extent, the erosion which was so common in clean cultivated orchards. Our better orchard soils have a sloping or rolling topography and a fairly high elevation. Under these conditions, in the absence of contour planting, any extensive tillage is certain to encourage both sheet erosion and gullying. But if mulch material is applied around the trees in sufficient quantity to smother the grftss more or less completely as far out as the tips of the branches, ideal conditions for tree growth and production are main- tained without danger of erosion. Furthermore, the tremendous demands of an apple tree for water are better satisfied if rainwater penetrates v/here it falls instead of flowing to a lower level, as occurs when a heavy rain falls on a bare soil. Another advantage of the Sod-Mulch ^stem over plowing and cultiva- tion lies in the maintenance of a smoother orchard floor. This makes it easier to travel through the orchard with a power sprayer or a truckload of apples. Plowing leaves dead furrows which are difficult to level off even v/ith a disc harrow. Many of our orchardists are broadcasting a complete fertilizer be- tween the trees, in addition to supplying the nitrogen needs of the trees through a ring application of nitrogenous fertilizer. This practice, of course, adds to the reservoir of organic matter since it encourages a better grovTth of the existing cover. It nay also bring about some replacement of plants in the cover, as for example, clovers in place of grasses. Since the supply of organic matter increases frora year to year under this system if of- fers an opportunity to disc once or twice, in spring, the strip between the trees and thereby bring about partial decomposition of the organic matter. This releases nitrates and other mineral elements for the tree and eliminates for a brief period the competition betv/een the tree and the cover crop. The tree is thus stimulated at a critical season, and later in the summer when tree (_^rowth should be completed, the cover crop has reestablished itself, and it proceeds to take up the nitrates which the tree no longer needs. Partial cultivation of the surface six inches and incorporation of some of the organic matter into the surface soil offer these additional ad- vantages i Soil aeration is improved. Compacting, due to heavy machinery, is corrected. And, in case the soil needs lime, an opportunity is offered to work it dovm beneath the surface. The magic influence of organic matter on the surface of the orchard soil and in the surfact layer are nov^ so apparent to the New England apple grovrers that plowing and clean cultivation are becom- ing obsolete practices. -.1*' GUinJING OF PEACH TREES Persons with peach trees are often disturbed by the formation of masses of gum on the trunks or branches. This gurming is the natural means of the peach tree in protecting itself. ' YiTherever there is a break in the bark, the sap oozes out, thickens, and forms a guiimy mass. It may or may not be a sign of serious trouble depending on the cause of the injury. If Johnny took a few shots at that peach tree v;ith his air rifle or cut his initials in the bark with his new jackknife, there is no cause for v/orry. The injury will heal over in time and the gum will disappear. On the other hand, there are some insects which e«it into the bark and cause trouble. The most common of these is the peach tree borer. The grub of this insect eats the inner bark, or carnbiuia, and young sapwood. It usually v/orks near the ground line or just below it, although occasionally it is found v/ell up the trunk or even at the base of the main branches, Masses of gum at or near the ground level are a pretty good sign that peach tree borers are present. They are a serious pest and should be dug out with a knife or treated with paradichlorobenzene. Directions for the use of this material will be sent on request. Occasionally, when peach trees become very weak from improper care, shot-hole borers v.'ork in the tree. These little beetles make hundreds of little holes in the bark so that the tree looks as if someone had peppered it with a shotgun. The real remedy is to keep the trees growing vigorously, since shothole borers seldom attack vigorous trees. Strong stimulation of infested trees by heavy fertilization, pruning and cultivation may help the tree to outgrow the trouble but badly infested trees usually die. Although there are certain diseases which cause slight gum forma- tion on small branches and twigs of peach trees in this state, diseases which cause serious guriiming on the truiiks and main branches are not present. Therefore, any serious gum formation is probably not due to disease. Y/here the bark splits as a result of winter injury, where a branch is broken off, or v;here the bark is chewed by rodents, gum formation will take place. The remedy is to make the tree outgrow the injury if possible* — J. S. Bailey SPRIITG COIITROL OF PEACH TREE BORERS Can peach tree borers be controlled in the spring? This question is often asked by those who failed to apply control measures at the proper time in the fall. Because of low soil temperature in the spring, paradichlorobenzene, or PDB, has given universally poor results at that time of year and is, there. fore, not recomi.iended. Then v/hat about ethylene dichloride emulsion? Dr, Oliver I. Snapp of Georgia says, "Ethylene dichloride emulsion is effective at ■ low soii temperatures and, therefore, caii be used late in the fall and early in the spring, vifhen it is too cold for paradichlorobenzene to be effective," Fall applications of ethylene dichloride emulsion have been tried in the Experi- ment Station peach orchard for three years. Very good control of borers was obtained and no injury resulted when applications were made according to Dr. Snapp's recommendations. Since severe injury has occurred in some states and the rosipon for it is not known, this material is not being recomiTiended for general use at any time of year. However, directions for its application are available and vrill be sent to anyone wishing to use ethylene dichloride emulsion experimentally at his own risk. — J. S. Bailey PLAITTING CULTIVATED BLUEBEIglES planting tine is fast approaching and blueberries like other fruits are best transplanted in the spring, the earlier the better. -But first, where shall they be put? The place to plant blueberries is largely determined by the nature of the soil. If the soil isn't right, the bushes ivon't grov/. Lov/ "frost pockets" are not good pj.aces. In such locations the bushes may be in- jured by cold in winter or the crop nay be ruined by spring frosts. The cultJ.vated blueberry requires a moist, acid soil well supplied with organic matter. Tlie amount of moisture in the soil is very important because the blueberry will not thrive with either too much or too little. Being a native of the sv/amp^ it will stand flooding during the dormant season but its roots must be out of water during the summer^ Hcn.vever.. a soil that is merely saturated with water but not flooded is very unsatisfactory. The freezing and thawing of such a soil heaves the plants out of the ground, breaks their roots and results in very poor grov/th. On the other hand, the plants grow poorly and bear little in a dry soil. A soil that is constantly moist but well enough drained to prevent "water logging" is the ideal. Most of the soils of New England are acid unless they have been lined. 1/fliile these blueberries will grov; in extremely acid (pH 3.5) to fairly acid soils (pH '0.6), they usually thrive best in soils classed as very acid (pH 4.5 - 5.0). The presence of wild swamp blueberry, leather leaf, cranberry, white cedar, or red maple indicates a good blueberry soil. V/hile most commercial blueberry plantings are on soils composed of mixtures of sand and peaty material, such a combination is not necessary as is shovm by the fact that so:ne plantings are grOT/ing well on sandy loaras, loams, and even mediura clays. For a coLimercial planting the land should be ploived and harrov;ed thoroughly before planting. If this can be done a year in advance and a cul- tivated crop grovm, or the land fallowed for a year, there v;ill be less dan- ger of grubs destroying the roots of the young plants. Those v;ho wish to grow a few plants in the backyard can remedy minor soil deficiencies if they are v/illing to take the time and trouble. If the soil has been limed, it is usually not acid enough for blueberries and is dif- ficult to acidify. Otherv>rise, a bushel of acid horticultural peat, which -9- should be thoroughly v;et before use, partly decayed leaves from liardwood trees, woodland turf or rotten wood from a decayed stump or log mixed with the soil in the planting hole helps to acidify the soil and retains moisture. More acidity can be developed by the application of sulfur or aluminum sul- fate. During dry periods in the summer, it maybe necessary to water the bushes . Commercial plantings of blueberries are generally set 5 x 8 or 6 X 10 feet. The planting distance depends on the fertility of the soil, that is, how large the bushes will grow, and the cultivating tools to be used. If cultivation is to be by a one-horse cultivator, rototiller or some similar narrow equipment, 8 feet between rovrs is enough. Hov/ever, if a large tractor and tractor equipment are to be used, 10 feet is none too much. If the plants are to be mulched - rotted sav;dust, shavings, acid peat, v/aste hay or straw are all good - and/space is at a premium they can be set 7 feet bet\:een rows. Blueberry plants transplant best if they are moved with a ball of earth. However, from nurseries in areas where Japanese beetles are present, it may be necessary to ship i/ith bare roots. VjTien the plants are received, they should be set as promptly as possible in holes a little larger than the root ball, and the soil firmed vrell around the root ball. They are best set a little deeper than they stood in the nursery. If the plants ai'e received ivith bare roots, the roots should be c arefully spread out in the hole and fine dirt sifted around them and thoroughly packed to eliminate air spaces. Ile'ver put fertilizer in the planting holes. It is likely to burn the roots. — J. S. Bailev LITTLE KIICT'ni FACTS ABOUT APPLE SCAB Several growers have shovm an interest in the details of the apple scab disease. Some of the following facts might serve a practical purpose. However, they are intended for the most part as informative and interesting information. Apple scab has been knovm since the early part of the nineteenth century. The fungus that causes the disease was first described by Elias Fries in Sweden, 1819. The first authentic record of the disease in America v/as from Hew York and Pennsylvania in 1834. The disease is world wide, occurring practically wherever the apple is grov-m. Pear scab is caused by a distinct but closely related organism. The pear scab fungus cannot attack apple or vice versa, A large share of the 80,000,000 lbs. of sulfur sold as fungicide is used against apple scab. Cordley of Oregon in 1908 successfully used sulfur as lime sulfur for control for the first time (per record). An estimated loss due to apple scab in Massachusetts for 1943 is 20^o and this is an underestimation. New York State figures a loss not less than' t. 3, 000, 000 annually. Yearly loss in Australia is estimated at ^48. 50 an acre. -10- There are tv/o spore stages of the fungus, the spring spores called ascospores and summer spores termed conidia. It is well to know these terms. Ascospores are shot forcibly from the old leaves on the ground a short dis- tance into the air enabling the air currents to carry them farther. At ttie peak of ascospore production, usually in the late pink, it is stated that in 45 hours 8,170,200,000 spores can be ejected from the old leaves on the ground in a 1600 square foot area. Keitt found an average of 2J9 ascospores per cubic foot of air in a 4 hour rainy period. Mature ascospores are ejected 5 minutes after the leaves become wetted. The spores change color in maturity thus making it easy to tell when they are ready to be shot out. Ascospores are four times larger than the majority of the sulfur particles in most sulfur sprays, A moderate amount of infection can take place on unprotected leaves between 63° F. and 75*^ F., when the young leaves are wet for 12 hours. It takes only 13 hours of v/etting \;ith temperatures betv;een 64° F. and 75° F. to get severe infection. On terminals, leaves below the fourth loaf are resistant to the scab fungus. If scab appears on such leaves they were inoculated when young. Although Daldv/ins are considered by many to be resistant to the scab fungus they may have as much infection as liacs. The fungus can change in its capa- bilities of attacking certain varieties. Careful cost and production records have shown net profits, due to spraying, of 4^65 to v<'00 per acre. The above are little knovm facts of my own choosing; the well knovm fact, of course, is that we still have plenty to learn about the disease and tlie fungus, — Thomas Sproston WORCESTER CONCERIT TfAIJTS APPLE ITOOD A much better offer for apple wood than was reported in February Fruit IJotes comes from a large manufacturer in Worcester.

In view of this unusual situation, it is of interest to reviev; the factors which are believed to influence the time of maturity of the v/inter spores. Past observations indicate that, as a rule in Massachusetts, winter spores begin reaching maturity about green- tip stage; a very small por cent are ready to discharge at delayed dormant; the period of heavy discharge is Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, V^illard A.

In some seaeons, epor« development lags behind this so-oalled average or normal course, and in others, it is ahead 6f fruit bud de7*lopment» In aay season, leavas under any particular tree may vary considerably regarding the time at which the scab fungus reaches the spore-discharge stage. One reason for the above mentioned variation among leaves is the difference in the tine scabbed leave* drop from the tree. Those that drop first, other factors being equal, usually develop winter spores first the follw;ing spring. Mild, wet weather in the fall between leaf drop apd the onset of winter usually favor* marked development of the young perithecia (winter spore-caseS) before winter weather forces them into a dormant state. Such perithecia are therefore likely to produce spores somewhat ahead of schedule the following spring. Hence, either premature defoliation or a *alld, damp fall may result in early winter apore maturity the following spring. An unusually late anow cover ysuaily is followed by a comparatively late period of winter spore Maturity. Likewise, regardless of what trans- pired in the fall and winter, a dry spring usually contributes to late spore maturity and delayed discharge, as oqcufred during the unusu&lly warm, dry ftpring of 1942 which forced fruit bude far ahead of the normal season. Con- versely, a wet spring, starting about the time fruit buds begin to swell, favors scab spore development even though the temperature may be so low that fruit buds make very slow progress. Such prolonged wet periods early in the 8pri3:>g are usually accompanied by cold v;eather, and such weather is likely to constitute a back^vard season for plant growth, as occurred in 1943. IThat is the situation this spring? premature defoliation last fall was common for scabbed leaves, and was followed by a comparatively dry fiill. There was very little snow cover during the winter, and spring, this year, started out cold and wet« At present, apple fruit buds are about two or three days earlier than in the very late season of 1943. Mcintosh buds jumped into silver-tip stage in Amherst on April 9-10 and they have remained there until the present (April 18), due to low temperatures. In Block A of the College orchard, on April 3 v;ith fruit buds dormant, the farthest advanced perithecia showed asci formed, but not spores. On Api:*il 11 with buds in the silver- tip stage, immature spores were plentiful, but no ripe ones. On April 17 with buds still in the silver tip stage, a small per cent of winter spores had reached maturity and discharged during the preceding night. In Block D, scab spores viere equally developed on April 11, following the warm period which forced fruit buds into the silver tip stage. Other orchards in Amherst ahow various intermediate stages of spore development, between sligf;tly earlier than normal and the stage in Block p at the College. If the season is normally wet from the present until blosscming time a majority of the spores in our Blo»k D will have been discharged by that time. And if scab spore development in commereisl orchards in other parts of the state is correspondingly early, which ia probably the case, there v/ill be an abundance of spores ready for discharge when the fruit buds reach the. delay- ed dormant stage. This means that, generally over the state, growers will have to be doubly cautious to prevent primary infection^, beginning at the full de- -3- layed dormant stage of fruit bud development, particularly since the scab carryover is heavy this year. Grov;ers vrho apply an oil spray will very likely need to add a dry Bordeaux, to give 2 lbs. of metallic copper to 100 gallons, or make an 8-8-100 Bordeaux, and add the oil to it, — 0. C.

But come to think of it, many of the now approved farm practices were novel not many years ago. The use of commercial fertilizers made headway slowly in the beginning. Some -4- farmers thought that fertilizers would poison the soil, and, strangely, some few still think so. The fanner who built the first silo in his community vms probably laughed at. Doubtless, the first orchardists to begin spraying were considered queer by their neighbors. So it is to some extent with conservation practices, albeit many of these have been used for years in some sections. Some New England farmers have always used conservation methods, some are now trying then for the first tine, and still others are considering their use. No doubt, the tine v;ill come v;hen fundamental conservation practices will be as common as certain cultural practices now are. Fruit growers as a group are among the most open-minded and progressive farmers, and it is expected that they will adopt soil conservation practices when they become convinced of their soundness and practicability. There are a fev/ good conservation demonstrations in orchards of Massachusetts. More are needed for educational purposes. Orchardists v;ho may want to try an adventure in soil conservation by way of contour planting v:ill be given technical aid in eo far as available technical personnel permits. — A. B. Beaumont POULTRY ItANURE AS A STRAVraERRY FERTILIZER Ov/ing to its relatively high nitrogen content, poultry manure is recognized as an excellent fertilizer for stimulating vegetative growth. It is used to good advantage in a young orchard, and if certain precautions are observed, in a strav/berry planting, but not during the bearing year, for at least four reasons; (1) It is a mistaken notion that a strav/berry plant can be forced into heavy production by liberal fertilization in the spring of the bearing year. Fruit buds develop in Septenber for the following June. For that reason no aiaount or kind of fertilizer between September and June will increase the actual number of berries. (2) Wiile an application of a nitrog- enous fertilizer in the spring of the bearing year encourages additional leaf growth, and consequently larger size berries, it also results in berries of poorer shipping quality. Loss in transit may be often traced to soft berries, resulting from a spring nitrogen application. (3) Increased growth of leaves, and incidentally of weeds, not only renders picking more difficult, but it prevents the berries from drying off after a rain. In a rainy season, such a planting presents a real problem in the form of decayed berries. (4) For obvioua reasons, the mere thought of clusters of luscious berries resting on a layer of poultry manure is distasteful, to say the least. Clean berries, such as are harvested in a planting mulched with straw or pine needles, represent this fruit at its best. It is not the intent of the writer to discourage the use of poultry manure in grov;ing strawberry plants. It is a question, not of the material itself, but of the time of application. Poultry manure harrowed into the soil in advance of setting the plants, works wonders in growing vigorous runner plants. The amount of poultry manure to be harrowed in will vary, of course, depending upon soil fertility. There is probably no better fertilizer for .5- growing strawberry plants thEin either poultry manure or v/ell rotted stable manure. More poultry manure should be used for this purpose in Massachusetts. Another very effective way of using poultry manure is found in stim- ulating the cover crop to be plowed under in advance of setting the plants. For example, if rye is sown on a soil which has received a liberal application of poultry manure, a heavy growth may be expected. Then as the rye is plov»-ed under, soil organic matter is greatly increased, and the strawberry planting is directly benefitted. One of the large producers of strawberry plants in Nev; England has adopted this practice with good results. He grows fine straw- berry plants on a soil well filled with organic matter from a rye crop stimu- lated by poultry manure. One other disadvantage of applying poultry manure in the spring of the bearing year is briefly thist As the strawberry plants develop in the spring, the tender pedicels or fruit stalks are likely to be burned if they come in contact v/ith this material. The writer recalls seeing a planting several years ago which looked as if it had been scorched by fire. The ex- planation was found in a layer of poultry manure wliich the v/ell meaning owner had applied around the plants in early spring, V/ith large quantities of poul- try manure available for agricultural use in Massachusetts, v/ays must be found to utilize this material to good advantage, A considerable quantity can be used by strawberry growers, not as a spring tonic in the bearing year, but as a means of encouraging a strong grov/th of runner plants the first year. If vigorous plants are grown, and if they are v;ell mulched in the fall, there is little or no need for fertilizers of any kind the following spring, BEE REPELLENTS In the spring of 1943 some experiments were conducted at the State College by F. R. Shaw and A. I. Bourne to determine the repellent value of some of the suggested bee repellents. The reader may ask, "Vfhy repel bees from fruit trees when they are known to be necessary for pollination?" The answer, of course, is that bees are needed only while the trees are in full bloom. They should leave promptly after they have accomplished their viork, since they may later be poisoned by spray materials. In these experiments the following test was made on 10 Cortland trees. Applications were made on May 22, using car- bolic acid, creosote, and a phenol preparation. The west side of each tree was Sprayed v/ith one of these materials, and the east side with a standard spray mixture, without any repellent. The most apparent result was blossom injury. This appeared in all treatments, varying from 10 to lOOjj. The injury was indicated by a curling and browning of the petals which dropped sooner than the untreated petals. There was also some leaf injury, evident as a browning and drying of the tis- sues. Some of the veins appeared blackened, followed by a cupping and crinkling of the leaves. Fruit counts at harvest time shov/ed no consistent differences in in the number of apples on the treated sides of the trees. Observations during bloom indicated that within one day's time there V\rere about as many bees on the treated as on the untreated branch'js. In these experiments there vms more in- jury to the tree from creosote than from the carbolic acid or phenol preparation. Feeding tests indicate that the addition of these materials tends to reduce the length of life of the bees. Y/liether this reduction is due to starvation or to actual poisoning has not been determined. 17ith our present limited knowledge of bee repellents, the general use of such materials cannot be recommended. -6- II'IPRESSIONS IN THE inJDSON VALLEY A recent visit to Ulster County across the Hudson from poughkeepsie renewed our impression that it is the habitat of up and coming fruit growers. 17e came away with a few definite impressions. (1) The absence of old neg- lected orchards. Practically all the trees Mere young to middle aged and vrare well pruned, vigorous and apparently productive. Spraying was already under v/ay (April 6). (2) Diversified plantings. 7/hile apple tro^^s were most evident, many pear, plum, cherry, and some peach orchards v/nre seen. Currants and grapes were common. This locality is v/ell adapted to fruit growing, and market connections v/ith New York City are good. But the most important factor is Y/ide awake, up-to-date ^^rov/ers. Vfc will not adnit that they are any smarter than Massachusetts growers but v;e must put on steam if v;e are to compete successfully with them. Many of our good orchards are growing old and we must have new plant- ings to replace them or we will fall behind in the race. V/hether v;e should grov; more fruits other than the apple may be doubtful. We cannot grow sweet cherries, and currants are out of the question in many localities because they harbor white pine blister rust. But why should vre not grow enough pears, plums and peaches to satisfy state markets during our season? Grov/ers would have to learn the fine points of the game, but that can be done. Incidentally, two grov/ers applied the new blossom thinning spray in 1943 to biennial bearing VJ'ealthy trees. At the time they thought they had ruined the trees, but they harvested a good commercial crop last year, and the same trees promise to have a good crop this year. — J. K. Shaw CONTROLLED- ATMOSPHERE STORAGE IN liWJ YORK STATE Our trip into the Hudson Valley on April 5 and 6 was mainly to in- spect, and discuss with the owners, two controlled-atmosphere storages. One of these storages is in Clintondale, operated by Mr. Jerome Hurd. The other is in I.Iilton, operated by Mr. Claude Hepworth. These men operate both con- trolled-atmosphore and regular storage rooms, Mr, Hurd's 8,000-bushel controlled-atmosphere storage was built some three years ago and was made "gas-tight" mostly by lining with sheet metal. He opened this room on April 1 and the apples were in good condition. Demand for them, of course, has been heavy, Mr. Hepworth 's 13,000-bushel room was made over into a controlled-atmosphere storage by the use of special paint over concrete v:alls and floor and aluminum foil on the ceiling. Many of the Mcintosh in this storage v/ere grown in Upstate New York, Both men are satisfied v/ith their controlled-atmosphere storages, even though this year they cannot get the usual premium of 50 cents to a dollar over ordinary cold storage Mclntoeh. Mr. Hurd is building another large storage and is planning to make up to one-half of this new space into controlled-atmosphere storage. Two such storages were operated this year -7- in V/estern Uevr York. At least three other nen in New York State are planning to build this type of storage and it is believed that after the v/ar, some 10 or 12 will be constructed. In short, there is an active and growing interest in this improved method of late storage for Mcintosh. The apples keep longer and in better condition, and stand up v;ell after removal. In the spring of 1943, controlled-storage Mcintosh were listed separately on the Nev/ York mar- ket and will probably be so listed again when pfice ceilings are a thing of the past. Considering its apparent success £ind its projected expansion in New York, it would seem that this type of storage should have a place in Massachu- setts. Controlled-atmosphere storage of LIcIntosh in this state should prob- ably be undertaken at first by a fov; individuals v/ho fully appreciate its special problems and advantages. The experience of the fev/ "pioneers" in Nev; York v/ould seem to justify the expectation of similar success on the part of a few progressive Massachusetts storage operators. ITe have had some experience in the -operation of a small controlled-atmosphere room at the Massachusetts State College and are convinced of its practicability. — Lawrence SOuthwick and 0. C. Roberts COSTS OF PRODUCTION All fruit growers are and should be interested in costs of produc- tion, not only his own but those of his competitor, because his survival in the industry may depend on lower per bushel costs. The grower has little control over selling price, but he can exercise some control over costs of production. In central l.'ashington it was found that the average cost of grovfing and harvesting apples in 1942 was 92/^ per packed box, but it varied from less than 60/ to more tlian 01. 60 per packed box. Packing and storage costs averaged 72/, making a total average cost of $1.64 per packed box, ready for the buyer. This total cost varied from $1.32 to $2,32. The prin- cipal cause of this variation was yield* Grov/ing and harvesting costs for those averaging less than 200 boxes per acre was $1.71 per box. This cost decreased with increasing per acre yields so that grov/ers v;ith yields of over 750 boxes per acre grew and harvested their apples at a cost of only 72/ per box. Growing and harvesting costs v;ere generally less in larger orchards varying from 80/ in smaller orchards to 67/ in larger orchards. (V;ashington Bui. 429). . „ ou ^ '^ ' — J. K. Shaw PEACH PROSPECTS FOR 1944 The cold weather of early April seriously reduced crop prospect* in southern areas* South of central Virginia to central Illinois there wafc more or less severe injury varying with area and orchard site. None has been reported north of this line. Indications are that while the crop in the southern area will be nearly tv^ice that of last year, it will be not much over half that of the 10-year average. Perhaps the northern peach grower is going to get a break this year, -- J. K. Shaw -8- Aii EASY y;ay to tiiin fruits (?) The use of caustic sprays applied at full bloom to thin apples and peaches has been investigated in various fruit growing states, in view of the prospective shortage of labor some of our growers may wish to try this method of thinning and promoting annual bearing of biennial varieties » No experiments have been made at the College but we expect to try it this year. We are not yet ready to recomriend this practice except as an experiment. We v/ould be glad to make suggestions to any fruit groiver v;ho wants to try it. Blossom spraying to thin fruits offers promise and v;hen v;o learn just hov; to do it, vre may adopt this nev/ practice in fruit grov/ing. — J. K. Shaw TREATIvlEHT FOR I.IAGIIESim.I DEFICII^NCY Some suggestions for the treatment of magnesium deficiency in apple orchards in Massachusetts are as follows; (1) Broadcast one to tv;o tons per acre of a high magnesium limestone, and work into the soil if possible. The limestone should contain more than 15 percent MgO. High magnesium limestone is available under the Atik program, it is often spoken of as dolomitic limestone. The use of limestone is ex- pected to help tremendously in effecting a lasting cure of the trouble. (2) Apply 5 to 10 pounds of Epsom salts per tree depending on tree size and previous symptom severity. This may be applied about the same time and in the same v/ay that nitrogen fertilizers are applied. The magnesium in Epsom salts will be more quickly available to trees than that in limestone. (3) Probably the quickest way to relieve magnesium deficiency is by spraying the foliage of affected trees with Epsom salts solution. Three special applications are suggested at v/eekly to ten-day intervals, beginning just after the calyx spray. Use 20 pounds of Epsom salts per 100 gallons of vmter. Lacking sufficient evidence on the safety of including the Epsom salts in the regular spray mixtures, special or separate applications are suggested. (4) Be cautious in applying potash to orchards that have shown definite magnesium deficiency sj,Tnptoms, Considerable evidence shows that potassium fertilization aggravates magnesium deficiency symptoms and there are appar- ently few orchards in this state that are suffering from an actual shortage of potassiuiii at the present time, — Lav;rence Southwick HEW SEEDLING APPLES Some years ago. Professor F. C. Sears started a Small apple breeding project at Massachusetts State College. Most of the trees have nov/ fruited for one or more years and, as might be expected, they vary widely in both tree and fruit. ■ 9- A very few have shewn sufficient promise to merit propagation and further testing. We have a limited supply of one-year trees of four of these seedlings propagated on semi-dwarf rootstocks in the Experiment Sta- tion nursery. Any grower who would like to set a few of these trees for trial may contact the writers at French Hall, Massachusetts State College, Amherst, Mass, Only a few growers cem be accommodated, of course, due to the small number of trees available. 1/e will allot the trees and send them out as soon as possible. There will be no charge except for express trans- portation and naturally there is no guarantee that any of the s<^edlings will prove to be worth naming.

This red pport was discovered on a tree in the Experiment Station orchard about 10 years ago, It was propagated and has nov; fruited at imherst. There seems little doubt that it is a red sport. It colors some\y field where, if conditions warrant, he plans to set a new orchard. S^'^eral holes vrere dug in this field to a depth of 2 feet or more to determine ivhat newly set trees may be up against. (2) Scarcity of plum curculio. In at least a dozen orchards care- ful observations were made to discover which pests were present. V/ithout looking at the nap vie were absolutely sure that we were not in Massachusetts, Plum curculio was conspicuous by its absence. Only here and there was a light infestation observed. Even where apple and plum trees were growing in close proximity to stone walls or brush land, plum curculio appeared to be a pest of minor importance. In a Kezar Falls orchard one particular tree (August Sv/oet) showed a rather heavy infestation of apple curculio, but no plum curculio beetles were observed. The orchard owner, Daniel Lord, reported a similar condition in that one tree in years past and occasionally a light infestation in his northern Spies, (5) Frost damage. Except in the University orchard at Orono where frost damage was rath3r severe j very little damage to apples or other fruits was observed in any Maine orchard. On the average,, the set of apples is rela- tively heavy and only in an occasional frost pocket is the damage worthy of -4- mention. Incidentally, Maine escaped the severe freeze which occurred in Ilassachusetts May 19. A later frost about June 3 caused some damage to vegetable crops but relatively little to fruit crops. (4) Among the fungus troubles observed were several rather severe infections of apple scab, particularly in orchards relatively near the coast where foggy conditions prevail. In two orchards plum trees showed evidence of plum Pockets and .in two peach orchards some Leaf Curl was in evidence. (5) Other miscellaneous observations. Orchard crowding is as much of a problem in some orchards as it is in Massachusetts. Cutting back of temporary trees which was done last spring, will provide temporary relief in one large orchard. A rough stony orchard floor in a Wilton orchard sug- gests a need for a few hours' work with a bulldozer, to prevent wear and tear on the sprayer and the -operator. Two heavy swarms of bees were observed within a few minutes in a cOuple of York County orchards. In both cases apple branches were heavily bent with the weight of bees av/aiting the magic hand of a beekeeper. Trunk damage to the extent of killing one tree entirely was observed, following the wrapping with heavy paper of doubtful chemical content about two years ago. The bark beneath the paper was in one case com- pletely killed. One enterprising grower with woodworking ability exhibited some sturdy, light weight step ladders which he constructs on rainy days, at the rate of about three per day. One grower with a block of exceedingly vigorous 5-year-old trees and a cover crop of equal vigor, is a strong be- liever in liberal fertilization. He used, in the form of ammonium. .nitrate, the equivalent of about 12 pounds of nitrate of soda per tree. Two spray rings are in operation with fairly good success. In one case where the op- erator uses a 500 gallon tank, it appears that the material is in some cases left in the spray tank too long, as evidenced by a black sludge on some of the trees. Spraying with epsom salts to correct a magnesium deficiency is becoming fairly common. One grov/er made a test of blossom thinning for the first time this year. The results, although variable, show some promise. As a final item, wo report a peach crop in one orchard in 1943 amounting to exact- ly one peach, a Rochester. How this peach in the top of the tree came through a temperature of 2CPbelow zero is a mystery, GRASS (from The Soil Auger) "Next in importance to the divine profusion of water, light, and air, those three physical facts which render existence possible, may be reckoned the universal beneficence of grass. Lying in the sunshine among the buttercups and dandelions of May, scarcely higher in intelligence than thope minute tenants of that mimic wilderness, our earliest recollections are of grass; and when the fitful fever is ended, and the foolish wrangle of the market and the forum is closed, grass heals over the scar which our descent into the bosom of the earth has made, and the carpet of the infant becomes the blanket of the dead. "Grass is the forgiveness of nature j- her constant benediction. Fields trampled with battle, saturated with blood, torn with the rut* of can- non, grow green again with grass, and carnage is forgotten. Streets abandoned -5- by traffic become grass-grown like rural lanes, and are obliterated; forests decay, harvests perish, flowers vanish, but grass is immortal. Beleaguered by the sullen hosts of winter, it withdraws into the impregnable fortress of its subterranean vitality and emerges upon solicitation of spring. Sown by the winds, by wandering birds, propagated by the subtle horticulture of the elements, which are its ministers and servants, it softens the rude out- line of the world. Its tenacious fibers hold the earth in its place, and prevent its soluble components from washing into the sea. It invades the solitudo of deserts, climbs the inaccessible slopes and forbidding pinnacles of mountains, modifies climates and determines the history, character and destiny of nations. Unobtrusive and patient, it has immortal vigor and ag- gression. Banished from the thoroughfare and field, it bides its time to return, and when vigilance is relaxed, or the dynasty has perished, it silently resumes the throne from which it has been expelled which it never abdicates. It bears no blazonry of bloom to charm the senses with fragrance or splendor, but its homely hue is more enchanting than the lily or the rose. It yields no fruit in earth or air, and yet should its harvest fail for a single year famine would depopulate the world." (John J. Ingalls) Biographical note; John James Ingalls was born in Middleton, Massachusetts, December 29, 1833 and died in Las Vegas, Hew Mexico, August 16, 1900; was graduated from \7illiams College in 1855; moved to Kansas in 1858 and estab- lished a law practice; held various territorial and state offices, and served as United States Senator 1873-1891; and from 1891 until his death was a prominent v/riter and lecturer.

The rainfall record in Ajnherst for the week of June 19 is as follows » June 19 - 64"; June 20 - 1.12"; June 21 - .19'!; June 22 - .OS'i June 24 - 1.84'!; Total - 3.64". Here we have almost as much rainfall over a six day period as we normally get in a whole month, and with uncounted hours of wet foliage it is easy to imagine the amount of scab infection which probably occurred in unsprayed Mcintosh trees. WHAT A BEE EATS. Bees need about 12 times their ovm weight in food in a year, just as humans do. For example, a man in the army, weighing 150 to 175 pounds, eats about a ton of food in a year. A ten-pound colony of bees needs 60 pounds of honey and four or five combs of pollen stored in the hive to carry it through the winter, (from The Furrow) SPLIT FERTILIZER APPLICATIONS. That this is not a new idea is shown by the following quotation from Jethro Tull, written in 1731i "There's no doubt but that one- third part of the nourishment raised by dung and tillage given to plants or corn at many proper seasons and apportioned to the different times of their exigencies will be of more benefit to the crop than the whole apply'd as it commonly is only at the time of sowing." -6- FRUIT AND NUT CROP PRC6PBCTS (June 1) A-Ts, 1934-42 1943 1944 Applas - Uass.

Grape production pros- pects are for larger crops in the eastern states but it is not expected that the California crop will be as large as the record 1943 harvest, although conditions are again favorable in that state. The apricot crop is indicated to be more than three times the 1943 record small crop and about one- third above average, California plums show a h% decline from 1943. The California prune crop is short with production indicated about 21^ below last year. Condition of Calif oniia almonds is above average and above June 1, 1943. The California walnut crop is inilicated slightly larger than last year's production. Prospects for filberts in Oregon and V^ashington, and for pecans in the important Southern states, are favorable at this time. Citrus production from the bloom of 1943 (marketings from the fall of 1943 to the fall of 1944) is a record crop, exceeding the previous season by aiiout 12 percent. Present prospects for citrus fruits from the bloom of 1944 (for marketing from the fall of 1944 to the fall of 1945) are favorable. (tiSDA. BAE Crop Reporting Boarci). ORCHARD SITES AS RELATED TO JHE FREEZE OF MAY 19 ' ' I I I I ■ II w^— .^^ I ■ V/hether the actual crop reduction in Massachusetts orchards, as a result of the recent freer0, amounts to 20, 25, or even 30 per cent, is something which will not ba definitely settled until harvest time. It may mm as high as 25 per cent* But this one thing is emphasized over and over again as we visit damaged orchards. The amount of damage is quite closely related to the air drainage and that, of course, has to do with the elevation of a particular block of trees with respect to the immediately surrounding country. Orchards in frost pockets fared badly. Orchards with good air drainage show, on the while, very little damage. And so as we look back at the severe freeze of May 19 we ought also to look ahead and give serious consideration to the site of our next orchard. However serious the damage this year may have been in a particular orchard, the frost will not be with- out some benefit if it results in a better location of our future orchards. DOES AMYBODY READ FRUIf NOTES? This incident provides a partial answer. On a recent visit to a good fruit grower in Norfolk County we found him seated in his truck about 10 foet from his mailbox reading - of all things - Fruit Notes. -7- Sm.aER DN BURIIS OUT SCAB SPOTS Apparently little has been published about the fungicidal proper- ties of Suiruner DN (DN-111). Judging, hov/ever, from its chemical relationship to Elgetol, one v/ould suspect that if applied at sufficient concentration it might possess some eradicative, if not perhaps even soiTie protective, proper- ties against such diseases as apple scab. Recent experi^snce with this material in one of the College orchards indicates that when applied at the summer concentration for red mite control, it possesses considerable eradi- cative properties for scab spots on Mcintosh foliage. In the afternoon of June 16, two I.lolntosh trees that had not been sprayed previously this season received an application of DN-111 (1.4 gals, in loo). Other trees in the same block wore sprayed vath the same solution to which load arsenate was added at the rate of 4 lbs. in 100 gals. At the time of the applications, the latter trees showed 18^i of the terminal shoots with light scab infection, while the unsprayed trees had 50^o and 10% respective- ly of their terminals infected. The temperature ranged from 83° to 85° F. and the humidity vms high. In the early forenoon of June 19, practically every scab spot on all of the sprayed trees where the leaves were thoroughly wet by the sprays appeared to be burned out. Tlie leaf tissue was brown and dead clear through the leaf. There was no visible injury to the leaves th-^^m selves except at the scab spots. Based on a macroscopical examination only, the eradicant action of the sprays appeared to be more uniform and complete and with less leaf injury than is ordinarily obtainable with a spray of liquid lime-sulfur (2 gals, in loo). Hov;ever, it is a bit early to pass judgment on the question of foliage injury since less than three days had elapsed after the treatments were made. If DN-111 spray at the summer concentration for red mite control should prove consistent and reliable as an eradicant for scab spots on the foliage, its use in scabby orchards would indeed be valuable aside from its effect on the red mite population. — 0. C. Boyd MORE ON BLQSSQLI THINNING SPRAYS VJ'e are looking for reports from growers who tried caustic sprays at blossoming time for thinning apples or other fruits. We tried this method on V/ealthy, Duchess, and Mcintosh, also on several varieties of peaches, using concentrations of from 1 to 3 piats of Elgetol in 100 gallons. A comparison is being made of one and two applications, and times of application as rela- ted to the development of the blossoms. It is too early to draw final con- clusions, but some preliminary statements may bo ventured. A spray of 2 pints in 100 gallons took off all or nearly all the fruits on moderately vigorous Mcintosh. Duchess trees were sprayed once, 2 pints in 100 gallons, on either May 9, May 11, or May 12. All sprays were more or less successful. Thespray on Muy 11, v/hen practically all spur flowers were open and a fev^ petals were falling, gave the best results. These trees need little or no further thinning. Similar treatment on VAjalthy on the same dates, when the flowers v;ere less advanced, apparently show no results from the early spray and only partial thinning from the medium and late sprays. -8- Concentrations of from 1 to 3 pints in lOa gallons applied once or twice on Y/ealthy in another orchard gave varied results. The first spray was applied on May 12 and the second (whan used) on May 15. Only the double spray, 2 pints in 100 gallons, seems to have thinned the fruits effectively. The weaker and the single sprays seen to have had some effect on the weaker trees which v/ere somewhat lacking in nitrogen. Nearly all sprays were less effective on the more vigorous trees which have been heavily mulched. These preliminary statements suggest that Mcintosh is easily thinned while Wealthy requires severe treatment, especially v/hen the trees are vigor- ous and high in nitrogen. Duchess takes an intermediate position. Perhaps we should use strong or double sprays on trees known to have the habit of setting heavily, and weaker sprays on trees known to set only moderately. Injury to the trees v/as less than expected. Measured by what we would expect from pesticide sprays, it v;as rather severe, but the trees now look all right and perhaps the spray injury weakened the trees less than would the setting of an excessive crop. All these trees (except the Mcintosh) have been distinctly biennial. Vflnether any of them will set a crop next year remains to be seen. Sprays of 1 and 2 pints in 100 gallons applied to peach trees in full bloom vfere only partially effective. All trees required further hand thinning. These trees showed little injury. -- J. K. Shaw FIRST YEAR TRAINING OF GRAPE VINES A recent bulletin from Ontario describes a new method of training a young grape vine which results in a straighter trunk and may hasten fruit- ing. A twine is tied to a side stub on the nevfly set vine, the other end of the twine being tied to the top wire of the trellis. Only one shoot is allowed to grov; and no lateral shoots are allowed to develop on it. As this shoot grows it is twisted loosely about the twine, two or three times during the season. liVhen the cane reaches the top wire it is cut off and tied. If the cane does not reach the top v/ire by the end of the first season it should be cut off above the lov;er wire and tied to it. Nothing is to be gained in pruning a vigorous vine back to two buds at the beginning of the second season as was formerly practiced. A word of caution is necessary on tying the lower end of the twine to the vine - be sure it is not attached to the main trunk below the shpot lest girdling result, Jf the trellis is not to be erected the first year a tall stake vali suffice in place of the twine, in which case the growing shoot should be tied to the stake, — A. P. French UNSCRAIvIBLING PLUM VARIETIES. A new bulletin, (No. 413), "The Identification of Plum Varieties From Non-Bearing Trees" by Lawrence Southwick and A. P. French is just off the press. It is well illustrated and v;ill help to accomplish for plum varieties what has already been accomplished through nursery certification of apple varieties. July 31, 1944 Prepared by the Fruit Program Committee of the Extension Service W. H. Thies, Extension Horticulturist Contents The Apple Maggot and the Blueberry Maggot Seen in the Field Fighting Farm Fires Thinning Peaches by the "Clubbing" Method Dusting for Oriental Fruit Moth Control Notes on Apple Insects Apple Crop Prospects THE APPLQ MAGGOT AND THE BLUEBERRY MAGGOT ARE THE SAME — ONLY DIFFERENT In comparing the apple maggot with the blueberry maggot, we find a brilliant example of "a gray horse of another color." The apple maggot has long been widely known as a destructive pest through eastern apple growing sections from Nova Scotia to Massachusetts, New York, and Pennsylvania. In Maine, it was a live subject of discussion in the State Pomological Society as early as 1882. Probably it was known in Massachusetts at an even eai-lior date. Although infestation in blueberries had been observed on wild land Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, Yfillard A. Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooporating. -2* for many years, it was not until 1906, that the late Dr» IJ. E. Britton, while State Entomologist of Connecticut, showed that the insect attacking blue- berries ia the same species as the "railroad worm" in apples. During more recent years a number of careful studies have been made of both the apple maggot and the blueberry maggot. A, D. Pickett and M. E. Neary, working in Nova Scotia, have shovm very clearly some of the relationships between the two pests. The apple maggot attacks apple* and thorn apples (Crataegus spp.). The blueberry maggot attacks blueberries, huckleberries^ snowberries, June berries, and a number of other berries. The apple maggot is larger than the blueberry maggot in every stage (egg, maggot, pupa, and fly), but', except for size, the two pests are as nearly alike as identical twins. The inter- esting observation is that the apple maggot can be forced to attack blue- \jerries, and the blueberry maggot can be forced to attack apples. Apparently in nature, however, the apple maggot does not attack blueberries, and the blueberry maggot does not attack apples. In experiments conducted in Wash- ington Coimty, Maine, very young maggots were transferred from blueberries to apples, and others were transferred from apples to Talueberries. After the transfer to apples, n^ormal, small-sized blueberry flies were produced, just as when the maggots fed upon blueberries. In the blueberries, the apple maggots developed to their normal, large size, but a single blueberry did not furnish sufficient food for an apple maggot. An additional blue- Ijerry was provided to enable the apple maggot to complete its development. Does this show a stage in the evolution of two separate species? Vfho knows? Perhaps some entomologist in the future can answer the question. (F. H. Lathrop, Maine Agr^l, Exp. Sta.) £[EEN tS THE FIELD Gangplank for Bees. For transferring a swarm of bees to a new hive Prank Foskett of Orange is using a sort of glorified gangplank consisting of a box, somewhat smaller than an apple box, with large holes bored in all sides, attached to the end of a long pole. V/hen this device is placed along- side of a sWarm of bees on a branch, they more or less promptly go aboard euid the o«mer carries them (at a safe distance) to their new home* This contraption may not be new although it is the first time the writer has seen it. Mr. Foskett rates recognition in the Gadget Department. Duster on a Skid. For his ingenuity in solving a thorny problem^ the CaoWs Corsage goes this month to Roger Peck of Shelburne. In the midst of a dusting operation a few weeks ago, a broken axle on a trailer supporting the duster gave way, and put one wheel out of commission. Instead of going fishing that day, Roger corralled a nearby fence post which he attached firmly as a Skid on tie disabled side, and in a few minutes the dusting op- fration proceeded without further interruption. When it's dusting time in the Peck orchard a little thing like a lost wheel or two cannot be allowed to interfere. -3- One Gallon Instead of Ten. A few days ago an extremely poor job of controlling scab was observed in an orchard where the present operator is getting his first experience in spraying. Although he thought he had sprayed five times, the trees show very little evidence of it. On inquiry, it vms found that a spray tank of. material is being stretched too far. The trees are receiving about one gallon instead of the ten needed for good coverage. Last Year's Spray Lime. Imagine using in the spray tank, hydrated lime held over from 1943. Although the spray chart specifies "freshly hy- drated" lime, one grower has been demonstrating that old lime will not do the trick. Having stood for a year, the lime is now partly carbonated and is gritty enough to resemble ground limestone. Clogged nozzles and a les- sened corrective effect generally result from using old hydrated lime. Bridge Grafts Too Short. Twice in recent weeks the writer has ob- served failures in bridge grafting. In one instance the ovmer said, "I seera to have very little luck in bridge grafting." V/e tried to convince him that success in this venture involves much more than luck. His diffi- culty lay in cutting the scions too short and in failing to insert them far enough beneath the bark above and below the girdled area. If ordinary pre- cautions are taken, including tacking the bridges in place with small flat headed nails and waxing the wound to prevent drying, at least nine out of ten of the scions should unite. A first class job of bridge grafting of a tree trunk one foot in diameter can be completed in less than an hour, and that's not a bad investment of time, on a tree which required 20 years for its development. Frost Rings on Pears. Some peculiar looking pears have been ob- served in a number of orchards this season as a result of the freeze of May 19. Some Bartletts have a v/ide russet band extending entirely around the pear about midway between the stem and the calyx, suggesting a variety v/hich combines Bartlett and Bosc. Maybe they'll rate a special market as "Fcincy" pears. Wild Morning Glory. This rank grovfing perennial with strong root- stocks seems "to be~closely associated with a pest of apple trees, the buf- falo tree hopper^ which lays its eggs in the wood of the terminal growth. V/liile this pest selaom causes severe damage, many trees shovY badly scarred branches ar, a result of the deeply inserted eggs. And very often, the more wild morning glory in the tree the more scarred branches are in evidence. TOiite Grubs, The need for a rotation of crops in strawberry grow- ing is well illustrated in a planting visit^jd a few days ago. A planting which bore in 1943 vras plowed under after the crop was harvested, beans were then planted, and last spring strav/berry plants v;ere again set on this par- ticular land, instead of waiting the usual three or four years before reestab- lishing a strawberry bodr in this field quite a number of the plants look wilted and on digging around the roots every one of them showed a white grub. Half a dozen plants were dug up v;ith the same result. This suggests the need for grov/ing tvro or r.iort. crops between crops of strawberries, for the purpose of elL'ainating white grubs. There are, of course, other reasons for a ro- tation, aiaong them the destruction of weeds, increasing fertility, and add- ing organic matter. -4- New Raspberry Seedling. A few years ago a raspberry plant, apparent- ly a seedling, grev; up in the flovi/er garden on the farm of Arthur Lundgren, in Orange. It was transplanted, and as new canes grew, the planting was ox- tended until now it covers an area about 30 feet square. This nevi unnamed variety looks promising. The fruit is large, of fairly good quality, and thus far the foliage shows no signs of mosaic. Planting Strawberries on Run Out Land. On a Hampden County farm a particular field of excellent soil "type shows evidence of continued crop removal v/ith little, if anything, put back. Fifty years or more of "mining" has left this field in an impoverished condition. None of the ordinary grasses are in evidence and the scanty weed grov;th consists mainly of acid tolerant plan'ts. The previous owner had continued to plow and cultivate until it may have been necessary to "prime the hayrake with last year's hay" in order to gather up the scanty crop. The present owner would like to es- tablish a strawberry planting of half an acre or so next year, if possible. To do so successfully v/ill mean strenuous efforts, to say the least. Brief- ly, these things v/ill be needed: 2 tons of lime per acre, a heavy applica- tion of manure, or of a complete fertilizer, and a cover crop sown immediate- ly to provide as much organic matter as possible. Even then, the chances of providing a soil good enough for strawberries next spring are very remote. It v/ill be easier to get the land in shape for planting in 1946, Sunburned Apples. In a Northboro orchard, quite a number of apples, amounting to perhaps 1% on some trees, show distinct sunburn. There is reason to believe that spray materials may be a factor. The trees have been well sprayed with a wettable sulfur, and in mid-summer an application of DN was made for red mite control. On the side of the apple exposed to the sun the skin has turned almost black. A combination of sulfur, DN, and strong sunlight may be the answer. Fewer Tentiform Leaf Miners. The heavy outbreak of spotted tenti- form leaf miner in eastern Massachusetts, so evident in certain orchards in 1945, seems to be on the wane. One orchard where this pest was very preva- lent last year shows very few miners this summer. Vif. D. Y/hitcomb hae found at least one parasite working on this insect and is of the opinion that the leaf miner may disappear from an orchard after about three years, Gypsy Moth in a Woods Orchard. In a Connecticut Valley orchard, immediately adjacent to pine trees, we have seen one of the worst outbreaks of gypsy moths in years. For protection against this pest, it seems highly desirable to "bring an orchard out of the woods." A Poor Combination. A combination of circumstances in one part of an orchard in the llashoba area indicates at least three things in need of serious attention. Those particular trees, on the average, look exceedingly sick. In fact, some of them are practically dead. The reasons are winter injury and mouse injury, induced by the follovnng system of management: A hear;/ application of poultry manure vms apparently placed around the trees, about tv;o years ago, in late summer. As a result, the trees grew too late for their own good and suffered from viinter injury. The poultry manure also caused a heavy growth of grass around the trees and that in turn encouraged -5- a build up in the mouse population in the heavy grass beneath the trees. To make matters still vrarse, the strips between the trees have been so persist- ently cultivated that serious erosion has occurred and only a scanty growth of grass is in evidence. We point out these three items, namely, applying poultry manure at tnevfime, failing to control mice, and long continued strip cultivation, as three reasons for an extremely poor block of trees. Fortu- nately, the rest of this orchard is under a much better system of management. Soils, Good and Bad. If it were possible to place side by side two orchards visited during the past few days, we vrould have an object lesson worth travelling many miles to see. In the first orchard, the soil is very sandy and the trees are seriously crowded. The foliage has a sickly appear- ance due to lack of nitrogen and v;ater, and the apples are failing to size up as they should. The grass turned brown during the recent dry spell. In the second orchard, conditions are the exact opposite. A fertile, retentive soil has shovm no sign of drought in either the tree or the cover crop. A rank grovfth of grass is in evidence and the leaves on the trees are unusually large and green. Yellow Transparant trees bearing a heavy crop show many apples 2 3/4 inches in diameter. The soil and the manager are two extremely important factors in fruit grov;ing. Magnesium Deficiency in a Middlesex County Orchard, A few trees about 25 years of age in this orchard showed mild symptoms of magnesium de- ficiency in 1943. These same trees are beginning to show symptoms again and the evidence is a little more widespread than it was last year. Evi- dently this particular orchard is on the border line as regards magnesium deficiency. An application of epsom salts will be highly desirable. In another block on this farm where symptoms'isere more pronounced, an applica- tion of epsom salts has corrected the difficulty. Other striking examples of the effectiveness of this material in providing needed magnesium in apple orchards are to be found elsewhere in the state. Rainy Day Jobs. Nailing apple boxes is one of the favorite rainy day jobs on a fruit farm, -fhis summer we have had so few rainy days that this important task has in many cases been left undone. As we approach the harvest season, we may have more rainy days, and we certainly have more reason to survey the box situation. Spare time should be used in such jobs as nail- ing box shocks, repairing boxes, and if both of these tasks are completed, we night use the next rainy day in looking around for more apple boxes to take care of the extra bushels on those trees vxhich we thought were entirely frozen out, Hold-Over Maggot Flies, In one of the YJ'altham cages v;hich housed maggots of the 1942 season only, \i. D, V/hitcomb has observed five flies this siunmer. In other words, five flies failed to come out in the summer of 1943 and have emerged after spending two winters in the ground. This behavior has been reported before, although it is interesting to have actual evidence of hold-over flies in Massachusetts. Meeting of lfe.ssachusetts Fruit Growers - Rice Orchard, Ilarlboro, 10:00 A, 11,, August 19. .6- FIGHTING FARM FIRES A few days ago Edwin S. Hartley, V^yben Orchards, V/estfield, Mass., told of tv/o experiences with fires in his locality. In both cases, a power sprayer of the type used for orchard spraying was used to very good advan- tage. Mr. Hartley was asked to Jot down the facts as ho recalled them. Here they are. It is just possible that someone in Massachusetts may prof- it from Mr. Hartley's experiencej "Last spring a brush fire broke out in a 5-year-old block in our orchards. I discovered the fir© when it was quite small, but the wind was blowing and it v/as so very dry that three men couldn't keep up with it. I drove one-half mile to the barns on the tractor (at 18 m.p.h.) to get the sprayer and found that it had just been emptied in another part of the or- chard. ¥/o took five minutes to fill the tank two- thirds full and that gave the fire good headway. On returning to the fire it was burning over an acre of groimd on a hundred foot front and the brush and mulch were burning as high as fifteen feet in the air. Using a heavy duty type gun with a nozzle delivering 10 gallons per minute one could walk into the fire and smother the flames and drive the fire back into the burned area. A 12 or 14 gallon per minute nozzle v^ould have given a heavier fog but the smaller disc was in the gun. In five minutes the fire was under control. The city fire de- partment arrived but they realized thftt their equipment was hardly needed, oven the regular forest firo truck, so they left in a short time. Later, the crew that was off duty appeared in the sarvioe truck to see how good a job the sprayer v;as doing. "On another occasion a brush firo was burning in the Shaker Village district of V/estfield when a bam caught fire, both inside and outside. A farmer who was spraying nearby was called on for assistance. He drove across fields to the barn and sprayed it, smothering the fire promptly. Some C.C.C. boys v:ho were fighting the brush fire with knapsack sprayers emptied their sprayers into the power sprayer tank, and in fifteen minutes the bam fire was out and the house was wet down to prevent the flying sparks from setting that, too* "For ordinary grass fires a 6 or 8 nozzle head delivering 12 or 14 gallons per minute v;orks best. The man with the gun rides, and the driver moves along the fire line about 10 feet away. Using a power sprayer to fight firo is very fast and efficient. Several mon need to follow the sprayer with bags or brooms or knapsack sprayers to put out small flare-ups and stray sparks." The last radio spray message of the 1944 season (Number 22) was released July 24. The objective of those messages is not so much to tell each grower just what he should do in his particular orchard, but to furnish fundamental information about the seasonal behavior of fruit pests and to provide frequent reminders at a time when he can still do something about it. -7- THimJING PBACIIES BY THE "CLUBBING" I^ETHOD Hero are two reports on a nev; methvod of thinning peaches » Carl Henry of V/estboro says, "I am satisfied that the method I used saved rae considerable time and money. I used a light stick about the size of a brooi;i handle with about eight inches of rubber hose slipped over one end. I found tliat I could hand thin the lower branches nearly as quickly as I could vdth the stick. Therefore, I "clubbed" only the branches that I could not reach without the use of a ladder. It took me about a half day to get into the swing of this method. "I'/hether I shall continue to use this method next year v;ill depend on how the peaches look v/hen I harvest them this fall. I don't believe any injury was done to tlie tree or the remaining peaches but of course you cannot select the peaches to be taken off as carefully as by the hand method. By the hand method you should get a distribution of peaches something like this: d — 0 By the clubbing method it will be more like this: .0^... ... ^ . C5 «:j — Vfalter D, V/eeks of the Vforcester County Extension Service gave a demonstration of this method at a meeting of fruit growers in Leominster, He says, "'Club thinning' consists of knocking off the peaches with a short stick such as a broom handle, A piece of old garden hose is attached to the stick to prevent severe bruising of the peach limbs. Tw^'o such sticks, one about 18" long and one 30-40" work very well; the longer stick is used to reach the higher branches, \7ith a little practice one can thin much faster by the 'club' method than by the conventional hand method." DUSTING FOR ORIENTAL FRUIT MOTH CONTROL ji I I ■ . . Oil Dusts were developed and first used for the control of Oriental Fruit Moth in_Illinois in 1929. Extensive work by the Natural History Survey Division of Illinois has showTi that Oil Dusts are quite effective in combatting this insect. The use of this material has become a standard practice among grov/ers in many peach sections where Oriental Fruit Moth is apt to take its toll. Control of Oriental 'Fruit Moth by means of insecticides is never 100^ effective, but tho degree of control with Oil Dusts is sufficient to keep losses from this insect v/ithin reasonable limits. The present i;>aterial, for use just' prior to the harvest season, con- tains the following active ingredients: Petroleum Oil - 5^o, Sulfur - 1)1%, This dust is designed for use on peaches for control of Oriental Fruit Moth, Brown Rot, and Scab. The recommended practice involves applications at 5 day intervals, beginning 4 v;eeks before the fruit ripens. Thus, applications begin at an earlier date on early ripening peaches than on late ripening peaches. The objective is to maintain a light, uniform coating over the fruit during the period whon the larva of the Oriental Fruit Moth is apt to make its entry. The Oil Dust may have some ovicidal properties, but it acts prin- cipally on the young larvae as they hatch from the eggs and crawl to the fruit to make their entry. In the final analysis, the success of this material in the control -8- of Oriental Fruit Moth depends to a large extent on -tae way in which it is applied. The grower must faithfully maintain a ligh-| coating of Oil Dust in the orchard eveiyS days for a period of 4 weeks bgfore the fruit ripens. If he has a very heavy infestation to contend with, the dusting should be exceptionally thorough, FIXED NICOTIHE FOR CODLING MOTH CONTROL The following note concerning the use of fised nicotine for codling moth control comes from W. E. Tomlinson of the li7alth«i Field Station: "Fixed nicotine is effective in controlling codling moth, but not apple maggot. Since the Fourth Cover spray is as much for magjjot as codling moth control in most of our orchards, the lead arsenate must be us*,d. These two materials can be used together so long e.s no lime is present in, the spray, but since the lead arsenate talces care of both insects there is no advantage in using Black Leaf 155. After the Fourth Cover spray, lead should not be used be- cause of the residue, in which case fixed nicotine is the answer." TIIE APPLE MAGGOT SITUATION ■ Three peaks of 'jmergence of apple maggot flirs in the Waltham cages are reported by v;. D. ViBiitcomb: June 17 to 19, July I to 3, and July 17 to 19, Very few flies emerged after July 18, A larger percentage than was expected (57^b) of the original 600 maggots have already appearad as flies. There are prospects of fewer migrating flies in late season for two reasons; (1) Owing to the heavy late J.me and early July emergence, previous arsenical applica- tions would be likely to destroy more of the flies thr^n in other years, sind (2) Having emerged early most of the flies on unsprayod trees will' have lived their normal life span before late August, APPLE CROP PROSPECTS The 1944 apple crop in the U. S. has been es|iiiiated at 109,000,000 bushels. This is about half way between the bumper cr<>p of 127,000,000 in 1942 and last year's crop of 88,000,000 bushels. The state of V^ashington leads in the estimates with 24,000,000 bushels, followed by Hew York with 16,000,000, Virginia with 10,500,000, Miahij^an with 7,200,000, Pennsylvania with 7,000,000i CJilifornia with 6,ij00,000, Ohio with 5,500,000 and \Tost Virginia with 5*000,000 bushels. Massachusetts will have in the neighborhood of 2,000,000 bushels. Blightville Grouper - "If a man sprays tho)+oughly until the first of June, he may go fishing the rest of the summer."

If just one application is to be used on Mcintosh, it should be delayed until natural dropping is well begun (at least 6 good apples per tree per day) in order to insure protection through the harvesting period. 4. Remember that after about 10-12 days following an application, the "sticking" effect may be dissipated, resulting in heavy dropping. This is especially truo v;ith Mcintosh and harvesting must bo planned accordingly. 5. Spray, as nearly as possible, during the hottest part of the day. Applications are not very effective when the air temperature is below 70° F. 6. Apply dusts when air is quiet and the temperature is high. 7. Use plenty of material. Thirty gallons of spray or three pounds of dust are none too much for mature Mcintosh trees. Thorough coverage is abso- lutely essential. 8. Use spray materials at standard strength (10 parts per million). This strength is usually recommended by the manufacturer. For increased assurance of effectiveness, use 1^ to double the standard concentration, especially when only one application is to be made. However, the standard concentration is likely to be sufficient if the spray is applied thoroughly and under favorable weather conditions, particularly as regards temperature. Do not use lower than standard strength spray, 9. If Mcintosh trees shov/ severe symptoms of magnesium deficiency, drop- control applications probably v/ill not be effective. 10. Possible over-maturity of Mcintosh is a factor to consider in utilizing "Hormone" applications as growth and development of fruits proceed as long as they remain on the tree. Hence, in the latter part of the picking season, some of the apples may be a little too mature for extended storage and ehould be segregated accordingly, —Lawrence Southwick V/AR PRISONER PROGRAIl GSTS UI'IDER VfAY A certification of need has btjen made for 1000 prisoners of war to assist with the apple hurv>r-st in the Nashoba area. A wage h»^aring was held at West Acton to dett;rmine the prevailing v:age rnte, vdiich was determined to be 15 cents per bushel and 60 cents on hour at the farm. The Ilashoba F^'uit Growers' Association is sponsoring this program for the apple grov;ers in the area and they hav-e employed Miss Eileen Draper, Groton, to look after the business details for them. The Nashoba Fruit Grov/ers' Association has been informed that they may proceed to make arrangements with the Commanding Officer in charge of the prisoners at Fort Devens for their use. The committed is noiv at work making these arrangements. It is expected that there v;ill be about 1000 prisoners available for the fruit growers in this area. — -Roy E. Moser k2«* GERMAIJ YfAR PRISONERS IN MIDDLESEX COUNTY ORCHARDS For the past v/eek there have been a hundred German Vfer Prisoners in apple orchards in Middlesex County and the same number again this week. The first month the total number of prisoners requested is small as compared with the seven hundred ordered for the picking of the Macs the first two weeks of September, The officials at the Army post have been most cooperativg and helpful in every v;ay and are anxious to have the program run smoothly. To date the orchardists have all furnished their own transportation but if several growers wish to combine their units for transportation purposes arrangements for a bus may be taken up with the Nashoba Fruit Growers' Association, As far as results; the growers here reported varying numbers of bushels picked the first day from eighteen to thirty. This variation on different farms is no doubt due to the difference in supervision. These prisoners should be handled exactly as any other "greon" help and to get the best results thoy should be carefully directed. As for the much talked about rest period the army officials do not require this; it is entirely optional v;ith the grower. The wages according to the contract v;hich the Nashoba Fi*uit Growers' Association has drawn up between the Association and the grower are fifteen cents a bushel or sixty cents an hour. The contract requires the payment of a week's wages in advance at the rate of six dollars a day. Adjustments in these payments are made the following week betv;een amount paid and actual work done. All in all, to date the whole program of using prisoners of vmr has v/orked out most satisfactorily in this county, — -Ramona I. Davis Emergency Farm Labor Assistant Middlesex County APPLE HARVEST LABOR SITUATION IN TTORCESTER COUInITY With the apple harvest facing us again this year, it would be a good policy for our growers to contact pickers who worked for them last year and who were satisfactory, to estimate about how many more pickers would be needed to harvest the crop, and keep in mind to have adequate picking equipment. Last year many of the men could not use all of their pickers at one time because of a shortage of ladders and other equipment k This year, the Nashoba Fruit Growers have appointed a labor committee who have looked into the possibility of procuring German war prisoners to help out in the harvesting. To date, it is known that German war prisoners will be available, and any grov/ers 'who are interested in this type of help should contact the Nashoba Labor Committee even though they are not • members. Of course, the first step in acquiring help should be the utilization of the local talent. By this, I mean workers who live in or around the vicinity of the orchard. If then the growers are still in need of help, they should contact their Farm Labor Coordinator, -4- T^e, in VTorcester County, recruited over 1,300 pickers last year which consisted of men. women and boys. This year, however, v/e are trying to recruit only men. Again this year, lYar Ration Boards are allowing extra mileage to and from th'3 orchards for pickers v/ho will transport other pickers. Y/e have forms that the grower vfill have to sign, stating — that the picker is working for him, and the trips made per day covering a certain amount of mileage from city to orchard. We are in hopes of getting British sailors to go out and pick for seven to ten days at a time. Grov/ers who can use this help v/ill have to board and house these men. It would be a good policy for anyone *rho may want the British sailors to start thinking of camps or places v/here they could house" these, men. The growers should lot the County Extension Service knor; their needs as to the number of pickers that will be necessary to harvest the' crop, so that v/e may recruit sufficient help if possible, — -John A. Gatti Emergency Farm Labor Ass't, Vfo re ester County YOUTH IN AGRICULTURE If there is any one word which we will have reas')n to remember for years to c )me, I think it is "Youth." A short while ago we felt a boy, unless he was old enougii to vote, was of little value, rather limited in experience, and could not except in rare instances, be utilized efficiently. IVe seldom stop to think of the remarkable contribution the yo-origstai-s of today are mak- ing tovmrd the preservation of our Country. Without ''Youth." as we know it today, v;c could not operate our tremendously fast and efficient types of fine machinery; in the field of Industry and the nev;er developments, such as radar, plastics, and others, nearly all of which are carried on by our Youth, This is equally true in Agriculture. Without our youngsters it would have been impossible to plant, grow, and harvest our record-breaking crops of the past two years. Here in our County of Hampden v:e have had hundreds of these youngsters doing men's jobs. Last year over tv;o thousand different young individuals worked on our farms. There are still hundreds this year carrying on the sarae i/vay. It is not uncomiaon to see individuals belonging to this youth mass as young as eight or ten years old driving some of our small tractors and other equipment utilized on the farms which, in some cases, cannot be operated at all by the fathers and older men. This is also true in some of our orchards in Hampden County. Some of us take it as a matter of course to see youngsters picking and thinning ap- ples and doing other operations around the orchard. The youngsters have taken readily to this type of work although it is a little more difficult than pos- sibly work in the market gardens, V/'e can all think of plenty of youngsters v/ho failed on the job; others. -5- who were fired and v/ent back to the city, and we are. inclined to comment only on this type of worker. The sincere, conscientious boy or girl is seidom given credit for what he or she may bo doing, simply because we are comparing thoir labor with imaginery adult labor. In the aggregate, may I say the boys and girls, when considered in connection with fruit farms only> have done a commendable job. Combined v;ith the v;ork of others, this will have its effect on the County, State, and Nation for a long time after the individual has been forgotten. I cannot commend too highly the vast horde of youngsters for helping us older people through a very strenuous period which, I believe, we would not have been able to handle alone, — -George H. Harris Emergency Farm Labor Ass't. Hampden County JAI'IAICMS ON THE CAPE Despite the fact the crop will be short due to 18 per cent winter kill, a 30 per cent freeze Eind unusual damage by fruit worm. Cape cranberry growers have enjoyed a pleasant summer so far as labor is concerned and look forward with some assurance to the harvest season. The reason for this complacency is that they have had the services of 150 Jamaicans on their bogs this summer. They have been able to accomplish much work that might not be possible if the crop was normal or heavy. Early in September when the berries ripen, the present force of Ja- maicans vdll be augmented by 200 more, making 350 v/orkers available for the harvest operation. The first contingent of 150 arrived in Plymouth June 18. They had signed up last winter at a recruiting station in Jamaica and agreed to work here until December 1. Their trtuisportation was paid by the V/ar Food Administration. Besides paying their wages, the growers also assume respon- sibility for their transportation. Quarters for these men will be Camp Manuel, Plymouth, formerly occupied by a detachment of Army engineers. Seven barracks, tvfo mess halls, and recreation hall and infirmary are nov; in use. Board and room costs the Jamaicans a dollar a day. Frank T. V/hite, emergency farm labor assistant for Plymouth County, v/ho has had countless arrangements to make in connection with the project, feels that things have gone along so smoothly this summer that it is almost too good to be true. Most of the Jamaicans have a high school education. Others have attended college. A number have been taking correspondence courses this summer. They are politeness itself and their speech is distinctly British, Their names have the sai.io flavor^ Everal Tylor, Vivian McFarlane, Casley Bail- ey and Gladstone Aitchoson. They are not fast workers but are steady and willing and do not lie dovm on the job. Perhaps it is enough to say that the growers v/ould like to have them again next year. A new mg vie, in color, with many practical suggestion* for inexperienced apple pickers, is now available. It may be 'booked through E. S. Carpenter, Extension Ser- vice, M. S. C, Amherst, Mass, -6- LOOKIIJG AHE.AD IN THE FRUIT BUSINESS Just the other day, or, in fact, early in August, when apples v/ere selling at a pretty good price, someone said, "I suppose Llaine apples are not in yet." He was thinking of the days when Maine raised and shipped many ap- ples into Massachusetts, and eastern Massachusetts vms a very small producer of apples in a commercial way. Times have changed since then, and the Massa- chusetts apple crop is frequently several times that of the Maine crop. Back in 1912, there were very few commercial orchards in Massachu- setts. Most of the apples v/ere raised as a part-time, cash crop by men viho had other agricultural interests. In the last thirty or thirty-five years, hov^evor, apple growing has pretty definitely drifted into the hands of pro- fessional or full- tine apple growers. This has probably enhanced the quality and marketability of Massachusetts apples. Massachusetts nov-i produces enough apples to make it an attractive buying location for large apple buyers. That makes it really a better market for all of us. I think the same thing would happen in small fruits if the advantages of quick freeze multiply the length of the selling season so that vastly more people will produce small fruits. It may be possible to grow them in Massachusetts in sufficient volume to at- tract buyers and to develop cooperatively a better technique in growing and selling. I hope that we will never lose our youthful spirit, whether it be small fruite or apples, ■.Many of us who were worrying along v/ith young trees twenty-five years ago haven't set out many young trees in the last few years. I fear that v/e may be approaching a period of orcharding in Massachusetts when all the trees will be ma-bure trees. That is the condition that occurred in Maine, for in- stanc-e, before the 1934 freeze. They are now rebuilding a good horticultural business there. I hope we continue a moderate planting either of standards or some dwarf trees and continue picking a part of our crop from young trees. No one wants runaway overplanting but we should have an orderly system of young trees coming along. Louis A. Vfebster Acting Commissioner of Agriculture TRAINING IIIEXPERIENCED APPLE PICKERS (The following item from Seasonal Fruit Notes by H. A. Rollins, Exten- sion Horticulturist in Connecticut, is quoted here because it is equally appli- cable to Massachusetts conditions.) "The lack of sufficient trained supervisors is present again this year, Dr, Bradt, State Supervisor of the Farm Labor pro- gram in Nev; York State, stated at a recent meeting that growers often say, 'I can't take time to train this green help." A good many fruit growers will have to make use of 'green help' if their apples are harvested this year. Dr, Bradt made it very plain that we cannot just take these inexperienced apple pickers into the orchard and say, '♦Here are the apples, go to iti ' He explained that there were three rather important points for every fruit grovrer to consider in training inexperienced help. Jlis suggestions were: (1) Obtain the confidence of your worker, put him at oise, build up his interest in the job, and get him in the right frame of mind. (2) Present the job to him, tell him v^hat you ex- pect v/ithout giving him too many details, show him what you want done, and re- member it is all new to him. (3) Let him pick apples under your supervision J correct him if necessary and make him do it right; be sure he knows the job J check up on each picker after he has had a little experience. Tell him not to both'-r othnr pickers but go direct to the foreman v;ith any questions." -i'C>>. tJO ^ ^,c .5 CI. e ft c 6 :~- c B -P '■ c^ >>^ <^ ^ o ;< -p o to u r— • •H t, O <;-< c •'* -o ^' • ta T3 •S TJ -2 •' to 3 -H O rH h x; a, U) h -tJ !^ C' cj ;> 1-^ o :5g s^ jj u p^ C w 1 •d >v © .c; 1 >> -p > « ^ -p » -H to U3 1 r» a 3 -P •* (K S 0 ^~^ +5 to rH « • •H +5 •H p >> u 0 -^ 0 +> 3 ■rl "^ 0 -H 0 ^ 10 r-H fl ^< p: « -—^x: <.H C- x: > -p d V> ■:S XP S -H 0 Cv! -P 2 -P 3 Vt -P i.d c ^ 0 •4 0 -P 0 u n -3 J^.

It was foxond that the speed sprayer deposited less lead in the tops of the trees but more on the bottoms, and gave somewhat less control of insects and diseases, especially with Mcintosh. However, applications were made twice as fast with the same amount of labor, (proc. A.S«H«S», Vol. 44, page 129). FERIJATE FOR CEDAR RUST. Cedar rust is not the most important disease of apple trees in Massachusetts, yet it sometimes does great damage to sus- ceptible varieties such as Wealthy and Golden Delicious* Experiments in Virginia showed that Fermatg, l-g- pounds, plus 1 pint miscible kerosene in 100 gallons controlled cedar rust on both fruit and loaves almost perfectly. It also proved superior to Bordeaux mixture in controlling bitter rot. (proc. A.S^H.S., Vol. 44, page 107). SULFUR SPRAYS AND GROV'JTH. Y/e are changing from liquid lime sulfur to wetta- ble sulfur largely because of a feeling that lime sulfur is injurious to the trees. The RJiode Island Experiment Station has carried on a comparison of various sulfur sprays and dusts including trees v/ith no fungicide. After five seasons with Baldwin, the dusted trees were the larger in trunk diam- eter, followed by those receiving wettable sulfur and those with no fungi- cide. The Mcintosh trees receiving wettable sulfur and dust grew best, while those with no fungicide were the smallest of all. This suggests that Y/e may do very well if we do not spray young Baldwin trees but had better not omit scab sprays on young Mcintosh. Their figures confirm the idea that liquid lime sulfur does check the grov;th of trees and that a 1-50 spray is worse than one of 1-100. (proc. A.S.H.S., Vol. 44, page 99). LEAF AREA PER FRUIT IN PLUMS « Much has been published relating to leaf area and the size and quality of the fruit. EiJ^eriments in the State of Washington showed that with tv/o varieties of plums, at least four leaves per fruit were necessary in order to mature the fruit and to permit adequate fruit bud formation for the crop of the succeeding year. A larger number of leaves per fruit resulted in larger, better colored fruit, higher in sugar and, therefore, of better quality. It is possible that under our conditions more leaves per fruit are necessary. The regulation of leaf fruit ratio is a matter of judgment. Perhaps it is safe to say that at least 6 to 10 leaves per plum arc necessary under our conditions. (proc. A.S.H.S., Vol. 44, page 94). EXPLODING THE SKIN FROM APPLES . Apples placed in a tight retort and heated to 2400-2500 and then suddenly cooled by shutting off the steam and forcing cold water into the retort were peeled almost instantly with little waste. Potatoes were peeled and lima beans shelled by the same apparatus. A patent on the process has been applied for by the Ohio state University Research Foundation, (proc. A.S.R.S., Vol. 44, page 190). -3- VifAXING APPLES. One of the weaknesses of the Golden Delicious apple is its tendency to shrivel in storage. Ihis can be largely avoided by vraxing the apples, [[he Cornell Station describes a home-made waxing machine v/hich could be built at a prewar cost of about $300. On this basis, apples could be waxed at a cost of about 3 cents per bushel. V/eight loss vias reduced about one-half. \Yaxing must be properly done or the apples may develop an alcoholic flavor, (proc A.S.H.S., Vol. 44, page 183). A NETiY HEASON FOR GROYJING MORE PEACHES IN MSSACHUSEITS . We sometimes wonder why some of the peaches shipped into Massachusetts should not be replaced by home-grown fruit. Peaches shipped long distances must be picked earlier than those for the local market. Peaches, like other fruits, grow as long as they are on the tree. Experiments in the State of Vfeshington showed that increases in^i.z1%r&m the time of picking Elberta peaches for shipping to the time of picking for canning were as follows: Average circumference 12^, weight 35%, soluble solids '60%. Peaches are picked for canning at about the same stage as for a local market, peaches allowed to remain on the tree until the flesh begins to soften are more attractive in appearance, of better quality and you get more bushels. (Washington Expt. Sta., Mimeo. Giro. 8, 1943) . MOiffi ABOUT J.IULCHITIG ORCHARDS . Massachusetts fruit growers are interested in mulching orchards. The New Hampshire Station has started an experiment in a young Mcintosh orchard comparing the common sod system of culture, sawdust, hay and seaweed mulches. After two years little difference has been observed between sod and savj-dust or between hay and seaweed. Hay and seaweed have resulted in more and larger fruits of slightly less red color., and deeper green anci more dense foliage than sod and sawdust. Witch grass grew up through the sa;vduEt but only slightly through hay and not at all through seaweed. These results are similar to those of the Massachusetts Station and indicate the value of a hay mulch or seav;eed if you can get it. It also suggests that sav/dust is of doubtful value. (Proc . A.S.R.S., Vol. 44, page 49) MORE PEACHES IN MASSACHUSETTS. Walter piper says that there are practically no good peaches in the Boston market because natives are being sold at the farm. Supplies come mostly from the Virginia section. Y/hy shouldn't we supply Boston from more Massachusetts orchards? BUT plant the trees on high sites, exterminate chokecherries , select the right varieties, control borers, brovm rot, curculio, and oriental peach moth. Perhaps DDT will help in the future . J. K. Shaw MAG^TESIUl-1 DEFICIENCY, A limited number of reprints of a journal article entitled "Some Results in Correct- ing Magnesium Deficiency in Apple Orchards" are avail- able to interested growers. The authors, Lawrence Southv;ick and J. K. Shaw, report in this article the effects of spray and soil applications of magnesium on magnesium deficient apple trees at Mass. State College. Requests for this reprint may be sent to Lawrence South- wick, M.S.C., Amherst. -4- NURSERY INSPECTION t Four members of the staff of the Massachusetts State College uav« organized the Massachusetts Trueness-to-Name Inspection Service, sponsored by the I;& ssachusetts Fruit Grov/ers' Association. The members of the Service are J. K- Shav/, A. P. French, 0. C- Roberts, and L- South- wick. This move implies no change in this work which has been carried on for 24 years. It only gives it a name and the expressed approval of the orgahized fruit growers of Massachusetts. The v/ork of examining nursery trees for trueness to name has been completed for 1944. Several new nurseries have been examined and a few Omitted examination for this year. Yftien a nursery has been examined for two or three years, mixtures and misnamed trees are eliminated. How- ever, new ones soon creep in, often among buds from bearing trees. Our experience indicates that such buds are mixed quite as often as those cut in the nursery. Ihe examination includes apple, pear, plum, sweet cherry, and t.;o-year sour cherry; one-year sour cherry trees of certain varieties are difficult to identify, hence, the desirability of waiting until they are older, peach trees are examined j but, as it is difficult or impossible to identify some varieties as nursery trees, examination of peach trees is less satisfactory than that of other tree fruits. Nevertheless, a great many mixtures and misnamed, peach trees are detected and corrected each year. Bulletins describing the young trees of apple, cherry, and plum varieties have been prepared by the men of the Massachusetts Trueness-to- Name Inspection Service and are available on request to the Massachusetts Experiment Station. Bulletins on pears, blueberries, and raspberries are in preparation. A list of the nurseries examined for trueness to name may be obtained by sending a postal card to the Department of Pomology, Massachu- setts State College, Amherst, Mass. J • K • Shaw CAN YOU AFFORD TO REMOVE SOl'.ffi OF YOUR TREES? Many of our fruit growers have orchards in wiiich the trees are too close together and find it hard to get up courage to thin them out because of fear of reduced crops. A circular from the feshington State Experiment Station gives some figures. s A liYinesap orchard planted in 1905, 106 trees to the acre, wa thinned to 54 trees in 1925. In 1940 one-half of the remaining trees were removed from one-half the orchard, leaving 27 trees per acre, and leaving the other half with 54 trees per acre. Detailed records of costs, yields, grades, returns and profits for the three years 1940-42 are reported. Acre yields and expenses were reduced and grades improved by thinning. The fi- nancial results vary \vith different methods of calculation used. A reason- able way of figuring gives the following results^ -5- 1940 1941 1942 Close Open Close Open Close Open 3oxes per acre harvested Total expense ^Tet profit 794 $602 74 502 p59 38 972 $714 218 697 ;|J494 174 1021 $695 168 780 $528 186 This table shows that net profits from the unthinned area were greater for the first two years but in the third year the acre profits were $18 per acre larger from the thinned area.

K • Shaw TREE RIPENED FRUIT In a test by the Illinois Experiment Station in cooperation v/ith chain stores three types of peaches were offered for sale; (1) green ripe, (2) firm ripe, (3) treo ripe. Public preference vvas decidedly in favor of tree-ripened fruit even when priced 3 cents per pound above the others. 35 bushels of tree-ripened peaches were sold in the time it took to sell 4 bushels of green peaches. There was less loss of tree-ripened fruit because it moved out so much more rapidly. This probably would apply to peaches anywhere. V/ould Mcintosh apples sell faster in the fall months if they v;ere ready to eat when of- fered for sale? R. A- Van Meter "FARIvi HELP CM'T TAKE IT" "The help vre get today just can't take it. Why my ten year old boy knows more about farming and can do more around my place than any two of these 'greenhorns'. I can't spend all my tine showing this class of help hov: to do the work; if I do I won't get anything else done." These and similar remarks have been heard recently v/hon we have been discussing ' the farm labor problem with Massachusetts farmers. Ve agree with them 100^. In agreeing v/ith the farmers we havo neither helped nor altered the situation. V/'o hope that we appreciate both sides of the question, th© employer's and the employeo's, We realize the inadequacy of this type of help, that it is not capable of taking over a particular job at first and doing it efficiently v;ithout considerable supervision. Times have changed; we can no longer go to the store and buy everything vre want without bother- ing with rationing tickets. Neither can we stop at the gas station and say "Fill her up." In a sense farm labor is rationed and wq must make the b6st of the supply available and use it accordingly. Yes, farmers sputter about the help problem as v;ell as the rationing system. Non'j of us relish the many problems which the war has forced upon us. -6- Soon after Pearl Harbor,. Farmer Jones bought a new tractor with all the latest improvements. It was a magnificent piece of machinery. He was very careful while breaking it in and as a result has a machine that is giving him wonderful service. Likev/ise, a little more care in starting "green" and inexperienced help vrill preserve it for future use. It is not a question of seeing whether or not the new man can "stand the gaff" the first day by vrorking him from 5 a.m. to 6 p.m. with no time out between. Break him in gradually; he will last longer and do a much better job even as the tractor did. Hov; does a farmer train a colt? Does he completely harness the young animal the first day and work him 10 to 12 hours plowing or harrow- ing? Does he expect the colt to be able to do all types of farm work with- out careful training? What happens if the young horse is forced to do heavy work before he is physically fit to do so? The answers to these ques- tions are, for the most part, obvious. Young and inexperienced help is very much like the frisky farm colt; plenty of life and enthusiasm but short on knowledge and training, in order to get the most out of either, the farmer must have patience and self control. He should take time to teach the techniques of the various jobs. He should remember that jobs v;hich have become practically second- nature to him are entirely new to "green hands." Suddenly transfer a dairyman^ or a poultryman, or an orchardist, or a vegetable grov/er from his agricultural environment to the work of a radio broadcaster. Say to the farmer, "You are in charge of all the pro- grams for the day. There are the controls, 'mike', etc. Now go to it." ?/hat would bo the result? Probably disaster as far as the radio program !• concerned. No, this inexperienced farm help "can't take it" at first; neither can the tractor, nor the young colt, nor even the farmer as a broadcaster. — R. H. Barrett YfliAT IS DN? One needs only to glimpse the chemistry of the so-called Dn ma- terials to see how complex they are. It is fortunate that we can use them effectively for insect control v/ithout knowing anything about their com- position. There are at least six brands on the market, some intended for dormant use, only, and some for summer use. All involve a "dinitro" radical, Hence the term DN.

Purchases from the Pacific Northwest will consist of Extra Fancy and Fancy grades in the 175 to 252 (per box) size range. That approximately 100,000 acres of orchards were sprayed v/ith hor- mone materials in 1943 to prevent premature dropping? In 1940, tho first year the chemical was used commercially, about 35,000 acres of apples wore treated. In 1941, 50,000 acres vrere treated, and 75,000 to 80,000 acres were sprayed in 1942. be That more than 9 million bushels of appl&s will/used in the United States in 1944 in making vinegar?

Hiat airplanes are becoming a major factor in the introduction of plant pests? The U. S. Bureau of Entomology and Plant Quarantine, in a recent report covering 13,093 airplanes arriving at 23 ports of entry last year from foreign countries, shows that 3,219 or about 25^ were found to be carrying prohibited plant material, much of it from places v/here it is laiown to be the host of injurious pests. There were 681 actual intercep- tions of insects and plant diseases, including sweet orange scab, citrus blackfly, Mexiciin fruit fly, V/est Iji^dian fruitfly, and Mediterranean fruit- fly.

Refuse gas lime, coal ashes a nd pitch, and vinegar vrere also rocomnendod. A severe outbreak of grape mildew before tho Civil War resulted in the abandonraent of thousands of acres in southern Ohio by 1869. Specific plant diseases have been re- corded over since Bible times. That dry weather may affect the availability of mineral elements in iflie soil? gjT.ptOTus of magnesium deficiency are always more severe during a dry season. Sojr.e interesting information along this line is contained in a recent letter written by Dr. Ekblav; to John Rice- Speaking of the effect of the drouth on the apple crop, he says, "This year the crop has been so heavy and the drouth so severe, that the moisture in the upper foot or two of the soil became critical for best production. Vi/henever the moisture is deficient in the soil the rate of disintegration and decomposition of the minerals that yield essential plant foods is drastically diminished, and for several years there is likely to be a lag in the amount of such minerals available in the soil. Another item to be considered is the fact that certain bacteria and fungi are mpst numerous in the upper layers of the soil Vifhioh this yoar have been driest, and their action both on organ- ic and inorganic materials for plant fqod has boon substantially reduced. "I love the great out-of-doors; the saell of the the soil; the touch of the rain; the smile of the sun; the kiss of the wind; and the laughter of the summer breezes in the trees." (Host Mcintosh growers failed to note any laughter in the breeze of September 14, and the kiss of that particular wind seemed more like a resounding smack.)

The i'igur'fes probably ijidicate, only in a general way, the chances of trees on these stocks being injured by high winds. Some of them can be set back without much damage. It is significant that none of the trees on the semi-dwarf- ing Mailing V nor on any of the so-called "standard" stocks suffered injury, Mailing IX is not advocated for commercial orchards, and wherever it is used in backyard plantings, we have recommended some support for the trees. Me have never recommended Mailing III, It is unfortunate that trees on Mailing IV suffered so badly. Many of the damaged trees were broken at the point of union, and so are a total loss. In many respects this is one of the best semi-dwarfing stocks, but if the trees aro to suffer like this just when they are ready to begin to bear, it puts a black mark against this stock. This orchard was exposed to an unusually severe test. In the 1938 hurricane our few trees on Mailing IV suffered no worse than others, but they were less exposed to the wind than were the trees mentioned in this report. Me need further observations before condemning Mailing IV, but it looks bad for it now. J. K. Shaw BUD SPORTS OF MCINTOSH We have growing in our experimental orchards about 20 strains or bud sports of Mcintosh each propagated from a known Mcintosh tree. One is from a tree of about average color, two are from trees which bore striped apples and the others are from trees selected because of real or supposed superior- ity of color. Seven of these strains have fruited, including the "average" strain; neither of the "striped" strains have yet fruited. There seem to be rather small differences in color. The "average" strain is a little in- ferior to most of the others and two of the strains seem a little superior but it will require further study before we are able to say positively which is the best, A strain of superior color may be inferior in other respects such as vigor, productiveness, etc. An experiment is under way which will show whether or not there are differences, other than color, among seven of these strains, —J. K. Shaw COIITROLLING RATS AND MICE VflTH METHYL BROMIDE IN APPLE COLD STORAGES From fumigation tests with methyl bromide run last May and again dur- ing October at the Massachusetts State College in cooperation with Lawrence Southwick, Research Assistant, Pomology Department it was found that this material is very effective in killing rodents without any observable injury to, or effect on apples. Methyl bromide was tested on both mature fruit respiring relatively slowly and freshly picked fruit. A good dosage seems to be either ^ pound per 1000 cubic feet of storage space for a 4-hour period qr ■§• pound for a 2-hour period. Since methyl bromide is injurious -3- to all forms of animal life, proper caution should be obaer-^ed vrtiAn handling it. Therefore, it is inadvisable for anyone except experienced technical personnel to attempt to handle liquid methyl bromide without first having attended a demonstration in its use. The use of trapping, poisoning, and even, proofing the storage has not been entirely satisfactory because ro- dents are carried in with the fruit or enter the storage through doors or chutes. It is significant, therefore » that this method of exterminating destructive rodents in apple cold storages has considerable merit. Those who have a rodent problem in their storage and wish to use this material should communicate with Mr. Southwiok. — -Robert M. Borg, Biologist U. S. Fish and Wildlife Service TfHEN ARE APPLES RIPE? Proper maturity for picking is vitally important to the apple grower, for the storage life of the fruit as well as its eating quality are greatly influenced by the stage of maturity at which it is picked. In the past, three guides have been rather extensively usedt (1) Degree of yellowing; (2) firmness of the flesh; and (3) ease with which the apple may be detached from the tree. Of late years, a fourth has been taking on increased im- portance—elapsed time from full bloom* Dr. Mark H. Haller, associate pomologist. Bureau of Plant Industry, Soils, and Agricultural Engineering, has recently completed an exhaustive check of these guides over a period of half a dozen years in the principal apple-growing sections of the country. He concludes that the growers have been leaning oil rather frail reeds in picking-maturity guides. The value of the yellowing or ground color guide, for example, has been considerably weakened by the increasing use of red strains that develop color before they are fully mature. Too, some of the standard varieties, under conditions favorable for red color development, color up enough to mask the .groxind color before the apples are fully ripe. Firmness of flesh is hardly a safe guide, Haller argues, since pressure tests indicate that the range at which maturity is reached is too great and the softening too gradual. And the accuracy of the ease-of-separating guide has been lessened by the introduction of harvest sprays to prevent fruit drop. It appears, however, that the number of days from bloom to maturity offers a relatively safe guide. For example, the number of days from bloom to Sfitlsfactory maturity for Delicious ajid Starking apples was found to be about 150, regardless of whether the apples were gi^wn in Vfashington, Oregon, Illinois, Ohio, Michigan, New York, or Maryland. Similar data are being obtained to show the best picking dates for the principal commercial apple varieties. WANTED - An orchard where trees are being removed by mesms of a bulldorer. We want to get some movie shots of this method of tree removal which it becoming increasingly popular in Massachusetts orchards. -4« HAKD POLLINATION IN ORCHARDS It may seem foolish to propose to run the bees out of their job by pollinating apple blossoms by hand, ynt this is done quite extensively in Pacific Coast orchards. Blossoms are collected at the balloon stage, al- lowed to dry for about 24 hours when the pollen will be mature. It is then collected in v;ido mouthod bottles and applied to the blossoms with a camol's hair brush. Effort is made to pollinate only one flower of one- fourth or even less of the blossom clusters. It is regarded more or loss as a temporary; expedient where there are not enough trees of pollinating varieties in the orchard. In some cases, hand pollination has given great increases in yield. It seems to require 1 to 2 hours to pollinate a mature tree. This mounts up to considerable expense but a bushel or two of apples per tree is ample reward. It is doubtful if this method should have wide application in Massachusetts but there laay be cases of orchards which have produced light crops due to lack of pollination in v/hioh it would be v/orth trying. If some of our grov/ers are interested, wo will be glad to prepare directions for trying this method. - — J. K. Shaw SPRAY nJG AND DUSTING BY AIRPLANE Imagine dusting 100 acres of orchard in an hour! This is the re- port from a large peach orchard in North Carolina. The results were re- ported as good with much more dust required than for machine dusting but the coverage was much better than with machine dusting. The second report of protecting the orchard from the air comes from Yakima, Vfashington. (Quoting from Better Fruit, "The plane flew three to four feet above the rows of trees which were a fourth of a mile long. Two trips were made over each row. The spraying proceeded at the rate of an acre in one ar^d one-.half minutes. The spray was 150 times as strong as that applied from the ground, and only 42 gallons were used on the 40 acres. Purpose of the application v/as to stop any dropping of fruit that might occur before harvest time arrived and before the fruit could be picked. The spray vms atomized into a fine mist that settled all through the trees as numerous specks on the loaves and the fruit." The report goes on to say that the hormone spray applied on Bartlett pears gave excellent results. The number of drops from trees sprayed August 8 was checked August 21 to 29. During this period an average of two pears per tree dropped from the airplauie sprayed trees wiiile unsprayed trees dropped an average of 113 pears por- tree. NOTES ON BITTER PIT Every few days someone asks the question, "How can bitter pit or Baldwin spot be prevented?" If an answer to this question were known it would have been given wide publicity. Some recent work Ih New York State, hovfever, conducted by R. M. Smock, throws sarae now light on this problem. His 12 point summary in Cornell Memoir 234 reads as follows j (1) ^plications of nitrogen during the growing season "to trees at -5- a low nitrogen level apparently increased the susceptibility of apple fruits to bitter pit. Injections of urea into single limbs resultsd in increased susceptibility. These nitrogen applications increased the osmotic concen- tration of the leaves more than they did that of the fruits, (2) Ringing seemed to markedly increase susceptibility to pitting. It increased the osmotic value of the leaves proportionally more than it did that of the fruits, (3) Defoliation vms the only orchard treatment that seemed to re- duce susceptibility to pitting. This treatment removed leaf-fruit competi- tion for viater. (4) Partial girdling of the fruit stems during the summer increased the susceptibility of the fruits to pitting. This treatment pre- siomably increased the osmotic concentration of the leaves at the expense of the fruits. (5) Fruits on heavily thinned limbs and on naturally light-crop trees were more susceptible to pitting than were other fruits. These con- ditions also were accompanied by an increase in osmotic value of the leaves at the expense of the fruits. (6) Oh an unthinned limb, the lateral fruits in a cluster were more likely to pit, both on the tree and in storage, than were the terminal f ruits, (7) Shading of limbs during the growing season resulted in increased susceptibility of the fruit to pitting. (8) Delayed storage is likely to result in a hastening of the appearance of bitter pit. The appearance of the disease may be significantly delayed by prompt storage, (9) Controlled-atmosphere storage delayed the appearance of bitter pit but did not reduce the final amount. (10) The use of high relative humanities in storage materially checked the rate of development of bitter pit. (11) There is a suggestion that,, at least under some conditions, the use of shredded oiled paper may increase the amount of bitter pit on fruits in storage. (12) Waxing of fruits with certain emulsions seei:ied to materially delay the appearance of bitter pit. BRUSH PUSHERS A simple device for gathering and transporting prunings in an orchard is being used successfully by several Massachusetts growers. No two brush pushers are exactly alike although the principle is always the same. In these days of labor shortages a little time spent this winter in construct- ing a brush pusher will return a good profit next spring. In its simplest terms, a brush pusher consists in a number of wooden teeth so arranged that they may be pushed along in front of the tractor. The construction is such that any farmer should be able to build one successfully. Here is a quota- tion from a recent Connecticut publication on this subjeoti "The teeth of the brush pusher — which slide along just toudhing the groiind at their front ends--slip under brush that has been thrown into the strip between two rov;s of trees. As the pusher moves along, brush is picked up until the teeth cannot gather or hold any more. Since the simplest brush pushers have no device to raise the teeth when a full load is accumu- lated, the operator must estimate how long a strip will make a load. The operator drives up a clear strip and turns into an uncleared strip at a point v/here he can just get a good load on his way back to the edge of the orchard. If he takes too long a strip, he will be overloaded before he gets to cleared ground. Brush is pushed out of the orchard to a location -6- convenient for a fire. Many operators push the brush directly into tho firo and unload by backing out. CAUTION j Be suro the tractor is driven by a good operator, that it is adjusted so that the engine will not stall, .and that it has a plentiful supply of fuel. One orchardist nearly lost his tractor because the engine stopped for lack of fuel just as he pushed the load of brush into the fire." (The details of construction will be furnished to any reader of Fruit Notea interested in this new gadget.) WOUND DRESSINGS ON APPLE TREES Valuable time is often wasted in painting pruning wounds which are so small that they would heal r«adily without treatment. In other cases the material has delayed healing instead of hastening it. In U.S.D.A. Circular No. 656, J. S. Cooley reports an extensive experiment in which -a number of wound dressings were used. Ho summarizes his findings as fol- lows : "The most promising of a large number of wound dressings were tested on the limbs of mature apple trees at Hood River, Oregon, and at Arlington Experiment Farm, Arlington, Va, Intemodal or side wounds 25 millimeters in diameter made at monthly intervals for 2 years were treated with two waxlike dressings in comparison with white lead and linseed oil, shellac, aad no treatment. One waxlike dressing (No. 541) contained eight parts by weight of rosin and throe parts of sardine oil; the other (No. 540) was similar except that it contained copper soap in addition. More rapid heal- ing took place in the transverse diameter; in the longitudinal diameter the wounds enlarged by dying oven v/here the best dressings were used. Even at the end of the second growing season the longitudinal diameters of the wounds were larger than at the beginning. "Wounds made in June or later produced little or no callus, in which cases enlargement due to dying took place in the transverse as well as in the longitudinal diameter. The longitudinal extension of wounds made in winter was in general greater than that of those made in the spring. The slightly injurious dressings caused less killing when applied in the spring than at any other timo of the year. Shellac gave more callus formation and less dying or longitudinal extension of the wound than any other dressing used. Dressing No. 541 gave better healing in general than white lead and Mnseed oil or dressing No. 540. The untreated wounds gave better healing in general than those treated with white lead and linseed oil, but poorer than those treated with shellac," TWO IMPORTANT PEST CONTROL I^EETINGS. The annual New York- New England Fruit Pest Control Conference will be held in Kingston, R. I. November 16 and 17. Research and Extension workers having to do with fruit insects and diseases will get together at that time to exchange ideas. Soon afterward the annual Massachusetts get-together will be held in Amherst at which time the various fruit spray charts will be brought up to date. -7-. U, S.

Rhode Island is down from 280,000 to 268,000 in September and Connecticut has been reduced from 1,635,000 to 1,456,000, SAN JOSE SCALE SHOWS STARTLING INCREASE In a number of Massachusetts orchards, particularly of the Baldwin variety, one of the most conspicuous harvest time blemishes is that caused by San Jose scale. In one instance the apples showed so many of the characteristic reddish spots as to make them scarcely recognizable. Not only v/as the skin plentifully peppered v/ith reddish spots but the calyx end showed a decided crust formed by a mass of these scale insects. More apples were apparently blemished by San Jose scale this season than in any of the past 25 years. To say that San JOse scale is on the increase is a mild under -statement. The reason for the present abundance of this pest in •one' oreharda is partially due to the fact that the use of a dormant or delayed dormant spray has quite generally gone out of style owing to the fact that a summer control of red nite is now available through the use of DN sprays or dusts. In the old days a generation or tv/o ago many apple orchards were completely destroyed by San Jose scale. That pest brought about the common use of dormant lime sulfur and it compelled apple growers to spray thoroughly if they wished to stay in the apple business. yie must n^Tw lesarn this lesson anew, 'Wherever any signs of San Jose scale appeared at harvest time plans should be made for a thorough dormant or delayed dormant spray using, not lime sulfu^ but one nf the oils or dormsint DN materials. AN ECHO OF THE GAY NINETIES. A few days ago an elderly man wrote to the State College to ask where London Purple might be obtained. This material was used to B'Wio extent before Paris Creen, and even that has long since been discarded as an orchard insecticide. ~8. MEADOW MOUSE SITUATION IN MASSACHUSETTS ORCHAPDS Due to favorable weather oonditions meadow mice ha-v© increased in numbers during the last mgnth (October), In fact, in a few orchards girdling has already occurred, especially on younger trees that were loosened by the hurricsme. Remember that girdling may occur even in low mouse pop\»- lation areasi Mice seem to have migrated from "certain" areas (stone walls, ditch bemke, wot meadows,- etc.) to the most favorable habitats and have established themselves. This is unusual because it was previously reported from a census study that meadow mice were scarce even in the best habitats, except in isolated spots. It is a wise policy, therefore, for every orohardist to check his orchard now ajid put out poison bait wherever necessary. It is only by a thorough inspection that the degree and extent of mouse infestation can be determined. All trees affected by the hurricane should be closely examined because "pockets" usually are formed vdiich make ideal harboring places for nice. —Robert M. Borg, Biologist U. S.

To avoid this calamity he offers these timely suggestions! (1) Blow the dust out of your motor, (fl) Be sure the con- nections are tight. (3) Put a little oil on it occasionally (not too much, just a few drops). This is particularly important if you are running it many hours a day, (4) If you possibly ciei, put in a safety fuse, of a size to fit your motor. This will not cost more than a quarter. Any electrician or dealer, or your Power Company, can tell you what size to get if you sim- ply tell them the horse power and amperage of your motor. This aafety fuse should be put in a separate fuse box. CLONAL ROOTSTOCKS. There is a demand, far exceeding the supply, for clonal rootstocks for growing dwarf and semi-dwarf apple trees. A new bulletin (No. 418) by J. K. Shaw is now available. It tells how these stocks are grown and identified. The old farm-home is Mother's yet and mine. And filled it is with plenty and to spare,- But we are lonely here in life's decline. Though fortune smiles around us everywhere!

One CEUinot get in or out of the fruit business as easily as in the case of vegetables, poultry, or dairy. On a strawberry farm, 13 months elapse be- tv^een time of planting and harvest. And if the soil needs improvement an additional year is required. In the apple business, the grower must think in terms of ten years, at least. Careful planning is needed now, in order to improve our competitive status in the post-war years. Older orchards and croyvding filler trees must be removed and new blocks established. Even though no apple trees were to be planted during the next ten years the total yield would not necessarily be reduced (assuming good care of present trees), although the cost of production would increase as the trees grow older, and a poorer grade of fruit would result. We must keep Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, V/illard A. Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. cur orchards relatively young if we are to maintain our favorable position among apple growing regions. In this connection the variety trend is of m«ch interest. In 1925, about 25jJ of our apple crop was of the Mcintosh variety. Today it is about 60^o. lie are becoming a "one variety state." There is a growing tendency in the fruit business to think in terms of new equipment, new spray materials, new fertilizers, and new varieties without paying much attention to the long time aspects of the business. Vfe are likely to stand so close to our present day problems that we fail to visualize what may happen five or ten years hence. Post-war planning is therefore of utmost importance. The fruit enterprise on every farm should be reorganized. High per acre yields of good fruit mean larger net returns. The 1944 apple crop in Massachusetts was almost exactly the same as the 10-year average (2,583,000 bushels as compared v;ith 2,586,000 bushels), This was about a quarter of a million bushels more than the short crop of 1943 and about a million bushels less than the bumper crop of 1942. Approx- imately 218,000 bushels of the 1944 crop were sold to the FSA in connection with the hurricane apple purchase program. Prices have been very favorable during both 1943 and 1944. This situation will not continue indefinitely. Fruit grov/ers must plan accordingly. Fruits other than apples should also receive attention. There is an excellf;nt opportunity for the grov/ing of more peaches provided suitable soil and site are available. The same is true of pears. The tine also seems favorable for limited planting of strawberries, raspberries, and grapes to supplement other enterprises, such as vegetables or poultry. An acre of strav/berries if properly handled, should yield at least 5,000 quarts. Strawberries should be considered by an occasional grower of tree fruits and by other farmers, as a supplementary enterprise. Problems Needing Attention; (1) Removal of older blocks, and planting of suitable varieties on good site's and~soils. Frosty sites and hopelessly poor 'soils imist hot be replantecf. The rejuvenation of our present productive plantings is much more important and significant thsin the establishment of nevi ones. (2) Orchard crowding. Filler tree removal, or the cutting back of temporary trees, is urgently needed in many orchards, (3) Magnesiwa deficiency. Severe symptoms are appearing not only in apple orchards but in some peach orchards, vineyards, and raspberry plantings. Every effort should be made to distribute high magnesium lime to those farms v/here such deficiency appears. The use of other magnesiura carriers, such as epsom salts, is also recommended v/here the deficiency is severe. (4) Improvement in the fruit pest control prograra. San Jose scale is on the increase. Red mite is causing severe damage in many orchards. Apple maggot is constantly a menace and must receive greater emphasis in 1945. Dusting as a supplement to spraying, is becoming a comi:ion practice. (5) Service to new orchard owners. Returning veterans interested in fruit growing" are entitled to whatever service vie can offer. They should be en- couraged to contact the county extension office for practical advice. With our present knowledge of the fitness of soil types for fruit growing we can render a very valuable service to newcomers in the fruit business. (6) Di- versification. On a farm concerned primarily with apples, some attention should be given to the growing of peaches or certain small fruits. On cer- tain other fams, one of the small fruits nay provide a profitable supple- mentary enterprise. (7) Nev/ developments. These include spraying or flusting to control pre-harvest drop, blossom thinning with Elgetol, con- trolled atmosphere storage, control of rodents in storage through the use of methyl bromide, and such labor saving equipment as the brush pushor, bulldozer for removing trees, stones, and for clearing land, and the one- man power spraying outfit. TALE OF OTO ORCHARDS Two farri visits in recent weeks offer proof that good pest control is possible even under the handicap of a low capacity sprayer, provided the ovmer uses it instead of lamenting his hard luck. Imagine an orchard of 200 mature trees and only a barrel sprayer to apply the needed spray ma- terials! Maybe the secret lay in the fact that the new orchard ovmer has an energetic wife viho provided the motive povrer on the pump handle and neither of then had been told that a barrel sprayer is a relatively in- effective piece of equipment. The facts in tlie case are that this man and his wife spent about three days, and laborious days at that, in applying a single spray on the 200 trees. They sprayed five tines. Vflien harvest tine came they had a crop of apples of v/hich any grov/er would be proud. At the tine of our visit the lady who had operated the punp handle during the suniner asked the question, "^Tl^at does apple scab look like?" Only after an extended search were we able to find a llclntosh apple which shov/ed a snail scab spot. These people have their ovm rev/ard for a season of hard work in the form of a beautiful crop of apples which hae . already found a ready narket at good prices. Orchard No. 2, composed mostly of Mcintosh trees, has for many years shown altogether too much apple scab. The trees are fairly tall and are making very vigorous growth. Last spring the ownor attended a meeting of fruit growers where he picked up an idea. Soneone at the meet- ing stressed the importance of spraying or dusting with sulfur during or immediately before a rainy period. Previously he had supposed that sulfur would only wash off during a rain and for that reason he might as well de- lay spraying until after the rainy period had passed. This year he deter- mined that he would try out a brand new system. And so instead of waiting for fair v/eather he got out the old sprayer, a snail one at that, and used it industriously every tine it rained- during the nonth of May. The results were almost unbelievable. In spite of his tall, vigorous trees, apple scab was conspicuous by its absence. For the first tine he had provided a protective covering of sulfur when it was nost needed. CORRESTIOIJ: Attention is called to a nistake in the October issue of Fruit Notes. On the 1st page under the heading "Anchorage of Apple Trees on Clonal Stocks," Mailing XII should read 0^^ instead of 21^^. In other words, this stock showed no breakage during the recent hurricane. -4- FIBRE APPLE BOXES. The Indiana Station studied fibre apple boxes last year and the results were favorable enough to warrant further tests in 1943-44. Boxes made of so-called "Victory Board," Grade A, gave the best results; Grades B and C vrere less satisfactory. The Grade A boxes were of ■•.023 caliper; weatherproof aheet on either side of a ,009 inch vreatherproof member manufactured with weatherproof adhesives. Such packed boxes stacked 8 high stood up well from October 1 to January 3. Y/hen stacked 10 boxes high, the weight proved to be too great. The boxes v;ere subjected to high humidity even to water poured on the floor. Massachusetts growers usually require a longer storage period eoid perhaps even these Grade A boxes might not stand up. (lloosier Horticulture Vol. XXVI, page 131, October, 1944) — J. K. Shaw MOVEI'iENT OF POTASH IN THE TREE. It has been thought that potash moves through""the tree rather readily in contrast to some other nutrients that move rath^-r slowly. At the New Jersey Station small peach trees v/ere planted so that the upper roots of each tree were confined to one pot and the lower roots were in another pot beneath. There could be no passage of water or nutrients from one pot to another except through the root that passed through the top pot into the bottom one. Potash could be applied to either the top pot containing the upper part of the root system or to the bottom pot containing the lov/er part of the root system. It was found that potash deficient parts of the plant were adequate- ly supplied viithin a very few weeks by potash supplied to either pot. It should be added that the pots v/ere filled with sand thus avoiding potash fixation v/hich commonly occurs in field soils. This suggests that when potash is applied in the orchard, it is not necessary that it penetrate deeply but it must reach the upper roots in available form. Probably few of our orchards suffer from potash deficiency. In attempting to correct an existing deficiency, one must beviare of bringing out magnesium deficiency. If the tree has absorbing roots near the sur- face, it may be easier than we thought to correct potash deficiency. (Soil Science, Vol. 58, page 51, July, 1944). -- J. K. Shaw YifAXING APPLES AGAIN. Certain varieties of apples have so little waxy covering that they shrivel in storage. Golden Delicious or Yellow Delicious is about the only such variety nov/ grovm in Massachusetts in suf- ficient quantity to warrant waxing. If Golden Delicious apples are waxed at the right time, with the right wax and in the right amount, shriveling may be effectively controlled. If waxing is improperly done, it may fail or the apples may be ruined. VJe would be glad to hear from growers who may be interested in v/axing, and if there is enough demand, to get some first- hand experience and to offer suggestions. — J. K. Shaw «5- 5^ ^ 7j^o Ji^n^r ?1U: That an injection of one of the Sulfa-drugs offers considerable promise in the control of X-disease in peach trees? Experiments now under way in Connecticut have shown startling results particularly v/here the material was injected in young trees previous to inoculation by budding with diseased material. That certain new organic fungicides are apparently effective in the control of apple scab by first penetrating the plant tissues, thus preventing entrance of the fungus? This fact offers an explanation of the protection given to newly developed leaves a considerable length of time after the material was applied. That the sale of Mcintosh apples in Niagara County, New York orchards increased from 1.3% of the total crop in 1922 to 23.9% of the total crop in 1942? During this same period Baldwin sales dropped from 45.6% to 20.4% while Greenings dropped from 27.0% to 25.4%. the That/Mclntosh variety has far outyielded all other varieties in the Hudson Valley? Considering trees in the 15 to 40 year class»the per acre yield of I.lclntosh during the period 1935-1939 was 429 bushels. Other varieties ranked as follows; Ben Davis, 266; Jonathan, 256; Rome Beauty, 249; Delicious, 217; Baldwin, 207. That 3,000,000 pounds of apple sirup were manufactured in the United States and Canada during the first year in v/hich this new product v/as pro- duced? Apple sirup made by the present process is amber in color, very sweet, and bland. It has no distinctive flavor and its consistency is about that of an invert sugar sirup of the same solids content. That Llassachusetts placed seventh among the states east of the Rocky Mountains, and tenth among all states, in apple production in 1944? That apple yields as high as 1000 bushels per acre have been re- ported in New England? Although exact yield records are not available three orchards in which the yield in a particular year amounted to at least that many bushels have been brought to our attention. V/e are interested in getting such records over a period of at least three consecutive years. Any grower who thinks he may qualify for the championship along that line is invited to submit the necessary figures. That it's time to mulch the strawberry planting? No other cultural practice is likely to return a better profit than this. Mulching works miracles by providing much needed protection against deep freeaing of the soil. It also keeps the berries clean and to some extent controls v/eeds. -6- F.ACTORS IN FRUIT GRgVING, CONTROLUBLS OR OTHERV^SE To a very large extent the grower of tree fruits or small fruits takes what nature gives him. Yields often vary by as much as 100 per cent or more. The reasons are obvious. Many of the factors which control growth and fruitfulness are very largely beyond the grower's control. In some fruit growing regions an adequate water supply is maintained by irrigation and damage from frost is prevented by the use of heaters. Under our condi- tions wo are likely to suffer the effects of too little rain one year and too much the next. If low temperatures occur "it's just too bad." To an evon greater extent no means of preventing hurricane damage have been de- vised. Unfavorable weather with all of its ramifications in the form of poor pollination, actual destruction of blossoms or fruit, and greater prevalence of insects or diseases is a problem with which the fruit grower must contend in one way or another every year. The point we wish to make is briefly this: Since many factors are beyond the grower's control it is only good business to control so far as possible those other factors over which some degree of control is possible. Of utmost importance we should mention the location of the fruit planting. Vihether strawberries or apples, the fitness of the soil and site should receive consideration, V^ith so many v^idely varying soil types from which to select, v;e ought not to handicap ourselves by setting valuable plants or trees where slight variations in soil moisture mean so much from the standpoint of yield and profit. If a soil type is so porous that it requires an inch of rain every week or if a hardpan is so near the surface as to result in water logging, the yield of fruit is certain to vary tre- mendously. On the other hand, a deep, well drained soil may withstand a month's drouth without seriously affecting the crop. This tends to em- phasize the need for making a wige choice of soil and site. Frosty loca- tions, in the light of a freeze like that of May 19, must not be replanted to either fruit trees or snail fruits. The same is true of many other low yielding plantings which fail to cone through with a crop just when prices are nost favorable. In short, a fruit grower ought to cooperate with nature by doing his part so well, including selection of location, pest control, spacing, choice of varieties, etc., that even "the vrorst that nature can do" will still result in a profitable crop. A VISIT TO TliE EASTERN REGIOIIAL RESEARCH LABORATORY IN PHILADELPHIA It was the writer's privilege on November 1 to visit the Federal Laboratory in Philadelphia where an outstanding piece of research in "The Recovery and Utilization of Natural Apple Flavors" is underway. By an ingenisus arrangement, the volatile esters in an apple are captured, dis- tilled, and returned to the apple juice. (Quoting from a recent report: "The numerous attempts made in this and other countries during the past 20 years to recover these flavors have never been completely successful, because either some of the more volatile components were lost or in the course of recovery the initial fresh flavor was inadvertently altered." This nem product is a colorless solution of tht volatila constituents of natural apple flavor concentrated from 100 to 150 fold. V/hen blended with apple juice concentrate and reconstituted with water, it is indistin- guishable in taste and arona from fresh apple juice.

The natural supply of magnesium in many of our soils is low, and since continuous removal through harvested crops, leaching and erosion, ■tends to reduce the avail- able magnesium below normal crpp requirementii, magnesium deficiency condi- tions become apparent on apple trees ai characteristic leaf scorch. Scorch- ing or dying of the leaf tissues usually affects irregular areas between the veins and shows up during August. Magnesium deficiency reduces tree growth and yield. Vfhere severe, apples not only fail to size up but drop prematurely (regardless of harvest spray or dust treatment). Issued by tho Extension Service in furtherance of Acts of May 8 and June 30, 1914, Vfillard A. Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. Two methods of treatment have been worked out, - (1) soil and (2) spray applications. With young trees, soil applications of epsom salts, kieserite, or seawater magnesia have given generally good results. Yfith older trees, delayed response from soil applications must be expected. Spraying seems to provide quicker, but perhaps more temporary, results. The inclusion of 20 pounds of epsom salts in 100 gallons of the usual spray solution in the calyx, first cover, and second cover sprays has given con- siderable control of magnesiuia leaf scorch in the year of application. In Maine, greatly decreased scorch syraptoms resulted from this treatment. Per- haps a fourth application in the third cover spray is advisable in some cases. Th:.s method of applying the magnesium in the regular spray schedule eliminates any spprfcio-ble expense of application and so far there has been no loss of effectiveness of either the magnesium or the fungicide. Briefly, the mere important suggestions for controlling magnesium deficiency in apple orchards are as follov/sj (1) Apply -'.-2 tons per acre of high magnesium or dci'' emtio limestone, af the soil is strongly acid (be- low pK P), Li/nestons carr-yi;ig 2Q% MgO xz preferred. This is probably the most important means of ascuring more or less permanent control. Repeated applications may be needed at intervals of possibly 5 years,, (2) Apply 5-10 lbs. per tree of ept?m saltSj kiet^erite; seawater magnesia,, or double sulphate of potash magnesiac In our tests, the seawater magnesia has given as good results as any material. (3) Add 20 lbs. of epsom salts to each 100 gallons of spray in the cal^^x, first cover, and second cover applica- tions. In orchards thus far free from magnesium deficiency sy:nptoms but situated in areas where the deficiency is known to exists a policy of pre- vention should be adopted . Insurance against future trouble from magnesium shortage can best be had by app-lying high magnesium IJ.mestone ever the en- tire orchard area at the rate of about 1 ton per acre. Subsequent applica- tions at intervals of '4- bo 5 ye'i.rs may forestall the serinus liiagnesium de- ficiencies now so prevalent in many commercial orchards. In any case, high calciu-'ii limestone should net be used. Vfiien ordering limestone for soil applications J be sure to designate high magnesj.um or lolonilio limestone.

An application of borax one year in three v/here- ever symptoms of internal cork have appeared in years past is coneidered excellent insurance. -3- THE FERTILIZER OUTLOOK Like the supply of other civilian goods, the supply of superphos- phate and nitrogen fertilizers has been reduced in the Llast six weeks, due to the demand for aanunition on the European war front. The supply of nitrogen fertilizers is reduced directly by this demand as nitrogen com- pounds are essential in the manufacture of explosives. Superphosphate supplies are reduced directly, as the sulphuric acid which is used in the majiufacture of superphosphate is consumed in the manufacture of explosives. This situation might change very quickly when hostilities cease on the German front. If the war activity in Europe should increase, there might even be a further reduction in both nitrogon and superphosphate available for agricultural use. Since the first of October, the available supply of superphosphate has been reduced from se-i/en million tons to six and one-half million tons, on the basis of 18^ superphosphate equivalent. The estimated supply had previously been reduced by one-half million tons. Consequently, at the present time, we may look forward to a supply of one million tons short of that available in 1944. Nitrogen. It is now estimated that 93 percent of the supply of nitrogen that was available last year will be available this year. The biggest re- duction comes in the supply of nitrogen solutions that are available for fertilizer mixes, and it is also expected that the quantity of ammonium nitrate will be much less. Stated in round figures and in terms of tons of nitrogen, it is expected that the supply will be equivalent to 588,000 tons, compared with 631,000 tons used in 1944. The supply of potash, fortunately, is ample, and is estimated to be 20^0 above the supply that was available in 1944. This should provide ample quantities for mixed goods and use for direct application. Mixed Goods. It is expected that there will be sufficient supplies of mixed fertilisers to meet the estimated needs for the crop season of 1945. The fertilizer industry is faced with the same type of labor difficulties that farmers face, and needs the full cooperation of their farmer customers. This cooperation can best be shown by ordering fertilizers and taking de- livery as soon as possible so that the delivery season may be spread over a longer period. The total supply pf mixed fertilizers is expected to be equal to that of 1944. The increased use of fertilizers is a very important factor in the increased production accomplished in the last few years. A i*ecord tonnage of fertilizer was used last year, and it is expected that the total. use in 1945 will be only slightly less than that of 1944. Perhaps we can best visualize this by stating that it is expected that the supply of fertilizers available for use in 1945 will be' 172^ of the average supply used in the years 1S35-1939. (Presented by S. R. Parker at Food Pro- duction Goals Conference, Amherst, December 5, 1944.) -.4- ORDER SUPPLISS EARLY FOR 1945 Yfer-time scarcities and war-time demajnds for materials during 1945 again will govern the production of farm supplies of all kinds. Industries manufacturing goods for farmers are also medcing military equipment. Farm supplies will be manufactured largely on a basis of advance orders. More time than usual will be needed for delivery. Again this year it is neces- sary to ORDER EARLY: supplies, equipment, repair parts, and materials of all kinds. Machinery and Equipment. The total amount of new farm machinery and equip- ment expected to be available for the 1945 crop season for the country as a whole is approximately the same as was authorized for 1944. Distribution will be through dealers without the use of rationing certificates. It does not seem probable that the war situation will allow greater farm machinery production in time for use next year, and it is decidedly improbable that any larger amount of machinery will be available in the spring of 1945 than there was in 1944, The manufacture of farm machinery repair parts will continue at a high rate. Take Your Fertilizer Now. Yifar Food Administration warns "Now or Never" for assured farm supply of 1945 fertilizer. Stocks must be kept moving out now continuously to farms or the lack of manpower, transportation, and storage capacity will cause a paralyzing shortage. Unless farmers act quickly in placing their orders and are willing to accept advance delivery of materials, some cannot expect -their requirements to be supplied in time for use in plant- ing. The recent increased demand of the Army for more explosives threatens to decrease the supply of nitrogen to 95 per cent of that used last year. Only 85 per cent as much superphosphate is expected to be available. Al- though potash is being mined to furnish 20 per cent above last year, the slow delivery of this item from distant points of manufacture adds further problems for local mixing plants. Those who want fertilizer for crops next spring should order without delay and accept early delivery if they can se- cure it. This will help manufacturers to mix and deliver fertilizers steadily throughout the winter. It is our only assurance of getting fertilizer on time. Order Spray Materials at Once. Both manufacturing and distribution of spray and dust materials will be delayed by manpower shortages, overloaded and de- layed transportation, container shortage, and similar problems. The total supply of fungicides and insecticides is expected to be enough for essential needs if orders are placed early so that these needs are made known. An adequate supply of sulfur is assured only if shipments of the finished products are continuous, not concentrated next spring and^ supimer during the peak of consumption. France is expected to use next year large quantities of our copper sulfate. "Industry expects supplies of this ma- terial to be adequate but early shipments are essential." This year's shortage of nicotine sulfate was due to heavy foreign demands. The nicotine situation may again be critical in 1945 unless industry and V/ar Production Board are informed ahead of time of our domestic requirements. -5- The following is the outlook for certain fungicides, insecticides, and weed killorsj Sulfur and copper sulfate ample if bought early; copper oxide and monohydrated copper sulfate limited, tight; lead arsenate and calcium arsenate adequate; cryolite plentiful; nicotine tight, uncertain; arsenical, chlorate and sulfamate weed-killing sprays tight, limited; like- wise sodium hydroxide eind sodixim arsenite for compounding homemade weed- killing sprays; sinox weed killer probably more plentiful; formaldehyde ajid mercurials probably adequate; fermate tight, limited; arasan probably ade- quate. Other common spray materials, seed disinfectants, as well as spread- ers and stickers are expected to be adequate. Make Plans for Boxes Now. Market boxes, and shipping containers of all kinds, are not expected to be any more plentiful than in 1944. Used orange crates and other second-hand containers are now being used for many new purposes. They may be harder to get this year than last. It ie not too early now to arrange for next season's boxes. Seeds. Supplies of legume and grass seeds, including winter cover crop seed, total 800 million pounds, approximately the same as last year. Gen- erally speaking, supplies of red clover, timothy, redtop, blue grass, and brome grass are more than ^mple for 1945 requirements. On the other hand, supplies of alfalfa, alsike, white and ladino clover are relatively short. Prices again will be relatively high. Vegetable seeds are expected to be sufficient to meet needs v;ith the exception of specific varieties of a few crops. Fencing and Hardware, More steel for the manufacture of such articles is available than in recent war years, but fencing and farm hardware still will be hard to secure due to labor shortages in manufacturing plants. Early ordering will help in securing adequate quantities, — James W. Dayton USE OF CANNON FOR- DUSTING The following is quoted from a recent International Apple Association release: "Robert D. Glasgow and Robert Blair of the New York State Museum are experimenting in spreading insecticide dust by a small cannon and report highly promising results for certain difficult conditions. They have over- come the problem of manner of firing the charges from a row of mortars so that ample distribution is secured over the area and find that it can be used for forests and for areas vAero airplane dusting is hazardous. Also this reaches the tops of the trees and assures thorough coverage of all foliage. New developments in dusting give promise for certain regions. The value of bombing will be particularly appreciated when the orchards are so wet that the sprayer moves with difficulty and scab or other dis- eases necessitate immediate protective measures. To be able to treat 100 acres or 500 acres in an hour, even by having a limited number of mortars which can be moved into position, will assure control over situations which have been up to now serious." H. P. Gilmore of Vfestboro comments as follows concerning the use of -6- cannon for dusting; "After the war we apple grcjwers should apply to War Department for all the old worn out cannon. Then our dusting problems could be solved. V/hy not load the cannon with properly mixed fungicide and insecticide with right amount of explosive then have time fuses so set that a set of cannon would go off about once a week during the spray season? Then we growers could all enjoy ourselves off fishing. Pephaps vie could find some way to reverse the process or use a vacuum and suck off all the apples at harvest time and thus save a lot of picking labor." A OrJE~;.IAN SPRAYER OUTFIT For his ingenuity in building a very successful one-man outfit for spraying a Jarge bearine; orchard, Vfilson Morse of Y/'aterford, Maine deserves recognition.- The thoroughness with which he spray^^ his relatively tall trees is indicated ty the faot that he has been able to produce for a num- ber of years crops of oppAes scoring at least 90Jo clean with no more than three sj.\ray appli jailor;-.. It should be borne in mind, of course, that certain posts including curculio are not as troublesome in Maine as they are in Wassarhusotts . The nozzle mechanism on Mr. Morse's sprayer is suspended at tho top of a pipe about 10 feet long and is so arranged that the dri-;er is able to manipulate the "broom" in either a vertical or hori- zontal direction. Quoting from a recent letter, "The pump is under. the tractor seat and is chain driven from a ball bearing power take-off on the front transmission. Two five-speed transmissions give us 24 different forward speeds, one of which is right for any size trees without stopping. " SUMIilARY OF TAIFA APPLE BUYING PROGRAM Massachusetts growers wore paid a total of $310,929.50 for hurricane apples purchased by the 7ff A,. These apples were distributed to institutions of various kinds and through the school lunch program in a number of southern states. One carload was shipped as far west as Ncth Dakota. Of the 218, £50 bushels of apples p'j.rcha!=edj 150,933 bushels were in Group 1 (mostly Mcintosh) and 67,582 bushelo were in Gt'Oup 2.

On a particular day when the air temperature was 32° F., thermocouples inserted in the cam- bium of the south side of an apple tree, which was exposed to the direct rays of the sun, revealed a temperature of from 60 to 64°. A similar measurement in the cambium of the south side of a peach tree indicated a temperature up to 83°, The cambium on the north side of the tree in no case showed a temperature more than 10° higher than that of the air. These measurements emphasize the tremendous absorption of heat by a dark colored surface. And when we consider the wide range in temperature of the tis- sues on the south side of a tree betv/een late afternoon and evening, after the sun has set, it is easy to understand why sunscald, splitting of the bark and other forms of winter injury sometimes occur. One of the larger dealers in farm supplies dis- tributed 40 tons of epsom salts among Massachusetts fanners last season, practically all of v/hich Viras used in orchards as a means of correcting magnesium de- ficiency. A report from Maine indicates the use of 33 tons of this material by fruit growers, for the same purpose. FRUIT NOTES INDEX FOR 1944 Apple Advertising. Jan. (6) Apple Buying Frogram. Dec.

An active research program concerned with Massachusetts apples and apple products v/as initiated in the Food Technology Department of the Massachusetts State College in 1927 and has been continued to date. In studies on the extraction of apple juice for the manufacture of jelly it was found that Red Astrachan, Red Siberian Crab, King David, ITine- sap and Mcintosh were among the more suitable varieties for apple jelly manufacture. A cider apple jelly has been developed which is a distinctive product of attractive color and appealing flavor, superior in quality to either apple jelly or cider jelly alone. Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, V/illard A. Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. -2- The successful canning of oven-baked, glazed, and dessert apples has been accomplished. Of twenty varieties of apples studied, among the best for canning were Northern Spy, Baldwin, Rhode Island Greening, Graven- stein, and York, The canned products are very attractive and of excellent flavor. A method has been developed whereby New England farmers having cull apples, a cider press, and a maple syrup evaporator can make relative- ly large quantities of pleasing applo syrup. Unfortunately, the juice of the Mcintosh, grown in this area, has a rather insipid flavor and must be blended with the juice of other apple varieties to yield a high grade processed apple juice. It has been found that blends with Baldwin containing up to 60 per cent Mcintosh apples yield a pleasing product. Much information has also been obtained and published on the manufacture of cider from Massachusetts apples. In addition to work on apple products, research has been carried on relative to the nutritive value of apples. Data on the vitamin G con- tent of 69 varieties of apples grown in Massachusetts have been obtained. Studies have also been made on the effect of eating apples on urinary acid- ity and blood alkali reserve, intestinal disorders and calcium retention. Studies have been made on the feasibility of enriching apple juice with vitamin C (ascorbic acid). A good quality apple juice has been made from a blend of 50 per cent Mcintosh and 50 per cent Baldwin apples, v/hich had a vitamin C content equal to that of orange or grapefruit juice. Dur- ing the past few years considerable interest has been shown in apple juice enriched with vitamin C, particularly in Canada, More than twenty different articles dealing with apple products EUid the nutritive value of apples have been published on the v/ork carried on in this laboratory, -- V/. B. Bsselon CONTOURING PEACH ORCHARDS Since peach orchards require both good soil and good air drainage, they are usually planted on more or less sloping land. Furthermore, since peaches usually do not thrive in sod, the orchards have been rather inten- sively cultivated. This combination of slope and cultivation has set up ideal conditions for soil erosion. In some orchards the effects are so apparent - washed out, barren, stony soil at the top* of the slopes and fine soil all at the bottom or in the next field - tnat one wonders why something hasn't been done about it. The remedy, of course, is contour planting. One of the College peach orchards planted on contours has given considerable evidence of the advantages of this system. The site of this orchard had previously been used for peaches planted on the rectangular system and cultivated both ways. This had resulted in the soil in most of the orchard, partiftulsj?!^ tiiali at the top of the slc^^^ becoming very -o- stony and very low in fertility. After the removal of this peach orchard followed by a few years of plowing in green manure crops to build up the soil, the site was again set to peaches in 1940. Contour lines were laid out with a surveyor's level, terraces built up v;ith road machinery, and the trees set at the outer edge of the terraces. In most orchards the ex- pense of building terraces would not be justifiable. If the trees are planted along the contour lines, cultivation will build up terraces in a few years. On very steep slopes terracing gives protection during the first fev/ years required to build the terraces by cultivation. Certain results of this method of planting in the College peach orchard are worth noting. First, the soil has been much improved by the cultural treatment, and this improved soil has been held in place. Second, run-off of water has been prevented thereby improving the moisture content of the soil. This has been particularly noticeable in the spring when large quantities of water vifere present. At times the terraces have looked like a series of rice paddies. This water has percolated into the soil in- stead of running off. And lastly, the grovrth of the trees has been improved. Following the very severe winter injury during the winter of 1342-43, the trees made an astonishing recovery. They did this in spite of a shortage of rainfall during the summer of 1943 when precipitation Viras considerably below normal in three of the five growing months. The conservation of moisture must have contributed greatly to this result. Anyone planting an orchard, particularly a peach orchard, where cultivation is to be practiced would do well to consider carefully the con- tour system of planting. — J. S. Bailey FALL NITROGEN APPLICATIONS .fiJID VmiTER INJURY Experiments i.i N-^w Hampshire seem to show that fall applications of nitrogen rendered app^. ? -.reGs iriore susceptible to winter injury. At the Maine Station nitr.>[;;-vn cirrj.ed in nitrate of soda, cyananiid, and manure have been appii ;d in Ifey; ;'V,(-a.st.

A recent report from Michigan praises Domestic Rye Grai'ss as a nev; orchard cover ci*op. Also known as Italian Rye Grass, it has shown promise as an over-wintering cover crop for Michigan orchards. Seeded shallow at the rate of 12 to 15 pounds per acre from August 15 to September 15, it makes enough growth to give ample soil cover for soil ero- sion prevention and excessive water "run-off." In the spring it resumes growth more slov;ly than comnion rye, interfering less vrith tree growth and cultivation. (Mich. Agr. Expt. Sta. Quart. Bui. 27, August, 1944). Kudzu. There is some interest in the possibilities of Eudzu for Massachusetts orchards. This plant was introduced into this eoiantry from Japan more than 50 years ago. By 1941, 250,000 acres of it -w©te planted on farms in this country. Kudzu is a rapid-growing, long-lived^ leguminous, viny plant having a taproot and long stems or runners. In the more northern part of its range, the runners kill back to the crown each fall and renew growth in the spring from crown buds. Foliage is abundant and the leaves look like grape leaves. Kudzu thrives best in the humid southeastern states. It has survived in somewhat protected situations in the East as far north as New York and Massachusetts but is better" adapted south of Virginia. Planting material usually consists of nursery-grown seedlings or crown plants. Relatively few plants per acre are required to obtain complete coverage. It seems doubtful that Kudzu has a place in most sections of Massachusetts, except in w<5 Unprotected locations. Further information is available in U.S.D..A. FarjnerS"' Bulletin No. 1923. — Lawrence Southwick VfALNUT TOXIC I'fY The question of walnut toxicity dates back to Pliny, the Roman philosopher, v;ho stated that 'H:he shadow of walnut trees is poison to all plants within its compass" and that it kills v^hatever it touches, accord- ing to G. A. Gries, Conn. Agri. Expt. Sta. Today it is widely accepted that the roots of walnut trees are toxic to the roots of certain crop plan.ts in direct contact with them. This toxicity is greatest to plants with tap root systems such as tomato and alfalfa and those with other types of deep root systems such as apple trees, rhododendrons, taid privet.^ ■5- The toxic component of walnuts is a chemical compound known as juglone. It is toxic to fungi and bacteria and has even been used in cur- ing skin diseases, including ringworm. In field tests in 1943 at the Connecticut Station on the control of black spot of roses, juglone gave a degree of control equal to that of 2^ times as much 325 mesh sulfur, the standard control for this disease, Juglone occurs definitely in the black v/alnut and the butternut, and probably in the English walnut. It is formed by the oxidation of hydro- juglone which is a non-toxic substance occurring in the inner bark and green husks of the nuts. V/hen roots of other plants contact these parts, oxidation produces the toxin and the roots are injured or killed. Thus root contact is required. In some cases, ihe plant root systems are shallow and do not contact the deeper roots of the walnut, especially in plowed ground. Also, some plants may send out sufficient surface roots to keep them alive in spite of injury to the deeper roots. This explains why many plants are not adversely affected wh'-in grown near walnut trees. However, the fact does remain that many plants, including fruit trees, often will die or not do v/ell in the vicinity of walnut trees. This is not a myth - it is a fact, — Lawrence Southv/ick RELATION OF McINTOSH DROP TO MGNESIIM DEFICIENCY We are just beginning to realize how low in magnesium are many of our crchard soils. This problem is not confined to the lighter soil types but may be equally severe in badly eroded soils and in other soils which are shallow because of hardpan, waterlogging or ledge. Strongly acid soil conditions, brought .about by the continued use of sulfur, has further ag- gravated the situation. Much of the apple leaf scorch previously attributed to spray injury is now known to be due to a shortage of magnesium. Fairly liberal use of potash fertilizers in some orchards has tended to accentuate the magnesium deficiency by creating a lack of balance between potassium and magnesium. Not that potassium isn't a highly essential mineral element. But a tree might "worry along" on a low magnesium diet provided other ele- ments were also low. As v;e step up the level of one element, we seem to create a demand for more of the others. Acontent of magnesium in the leaves amounting to at least ,2% of the dry matter appears to be necessary. Observations in Massachusetts orchards shov/ a much greater tendency of Mcintosh apples to drop from trees which are deficient in magnesium. Both leaves and apples tend to drop prematurely if the magnesium supply is very limited. It is .also well known that hormone sprays and dusts fail to produce the desired results under these conditions. One Middlesex County grower who has recently corrected a magnesium deficiency, reports that last fall, for the first time, he got a definite response to- the pre- harvest spray. Our first job as Mcintosh apple growers is to restore the magnesium balance. If that is done, the Mcintosh drop problem may partially disappear. -6- FACTORS IN ORCHARD PEST COIITROL If a fruit grovrer fails to get as perfect pest control as he had hoped, the chances are that one or more of the folloviing factors, maybe all of them, are responsible. Of these 10 factors, 6 are entirely or al- most entirely the growers' responsibility, 2 are partially so, and 2 are beyond his control. Three factors have to do with the spray program, 3 with pests, and 3 with the orchard, Vfeather is in a class by itself. 1. Location of orchard (environment, elevation, slope, etc.) 2. Spacing of trees (crovfded or scattered). 3. Condition of trees (height, spread, vigor, pruning, etc.). 4. Prevalence of individual pests, 5. Supplementary practices (drop disposal, banding, etc.) 6. Natural enemies. 7. Vfeather. 8. Timing of sprays and dusts. 9. Coverage. 10. Materials. • Storage Temperature and Relative Humidity. As the temperature of a stor- age room increases, the higher must be the relative humidity if the rate of v/ater vapor loss from apples is not to increase. At 32°, a relative humidity of 70^^ is as effective in retarding the rate of water loss from apples as one of 80jo at 41°. — Lav/rence Southwick Wartime Buying of Fruits. A study of retail sales of fruits in metropolitan markets has been made by the Department of Agricultural Economics at Cornell University. The information was furnished by a large Nev; York City chain grocery system and covers the period July, 1941 to June, 1942. In pounds of fruit sold» oranges made up GO.6J0 of the total; apples, 10. 9^^; grapefruit, 10.3^j bananas, 7-9°^; lemons, 4.2$^; peaches, 4.2^o. No other fruit was above Z%. Citrus fruits, as a ivhole, took 58 cents out of the average fruit dollar and accounted for m% of the fruit tonnage. -- Lawrence Southwick Fruit Growing, a Specialized Business. Cbily l/40 of the farms in the United States are classified as fruit farms. And yet these farms produce 5/6 of the fruit. This suggests the relative^mportance of the farm orchard from the standpoint of fruit production. Correction. In the December issue of Fruit Note?, under the heading "New Light on V/inter Injury," studies on tree trunk temperatures v/ere erroneously reported as under v/ay in Maine , This work is being conducted at the University of New Hai.ipshire by Mr. Russell Eggert, using the new Mi- cromax recording instrument. -7- PROPOSED UNITED STATES PIORT I CULTURAL COUNCIL Fred A. Motz , of the Office of Foreign Agricultural Relations, has proposed the formation of a Horticultural Council which will be qualified to speak for the fruit interests of the United States. The objectivTss are as follows; "To encourage closer collaboration between appropriate government agen- cies and the horticultural industry. To prepare factual data, to inform, to clarify, to consult and advise with, and to make recommendations to the Secretary of Agriculture or his authorized representative in the formulation and execution of programs which affect the horticultural industry. To set up a permanent council or advisory body representative ■ of specified commodity groups in the industry. It should be recognized by the Government as such, and the members thereof should be approved by the Government follov/ing industry nomination, selection or election. "The council should be made up of one or more representatives from each of the commodity committees that may be established. Any eligible com- modity groups desiring representation on the Council could make appli- cation to the council for membership. The council must have broad duties and responsibilities to achieve its purposes. It will be necessary for it to screen and analyze the information brought together by the com- modity committees and that available from governmental sources; to con- sider it in terms of appropriate relationships to other food and horti- cultural products and to the industry as a whole; and to advise and recommend industry and Government policies and action in matters deemed necessary to solve the particular problems," What They V/rite About. Thumbing through our pile of correspondence for the past month, we find inquiries on the following v;ide range of subjects (figures in parentheses indicate number of inquiries); Source of strav/berry plants (3), raspberry plants (3), pH for raspberries, preventing decay of strawberries, growing boysenberries , grape pruning, poar pruning, source of true-to-name trees (4), source of scions (2), peach varieties, black walnut toxicity.

New Apricot Developed in Russia. Soviet Russian scientists at the S amarkand Experiment Station have developed an important new type of apricot and one of apple, according to a New York Times dispatch from \7. H. Lav;rence, who accompanied Eric John- ston, U. S. Chamber of Commerce president, on his Russian Tour. The apricot contains 30 per cent sugar when ripe, it is said, and after ripening v;ill dry on the tree in 10 to 12 days with a 50^0 sugar content, or can fall and remain on the ground a month without danger of rotting, thus saving much labor in har- vesting. -3- FRUIT JUICE IIT CAIIDY FORI.I Following is a partial quotation from an article in the January- issue of Hoosier Horticulture. "Tremendous expansion in citrus concentrating facilities during the past year will present a serious problem for the industry after the close of the v/ar. V/hile there undoubtedly will be an enlarged demand for concentrated juices, it is undeniable that new markets and products must be created if virtual disaster is to be prevented. In considering the postwar possibilities for concentrated juices, several methods for appeal- ing to the consumer come to mind. First, of course, there is the familiar method of reconstituting the concentrate and using it as a beverage, either directly or as a base for •ades ' and carbonated beverages "Another method for presenting concentrated juice, v;hich apparently up to the present time has been completely OTerlooked, is to consider the concentrate itself as an entity, a substance in its own right. lYith this conception, additional fields may be opened and wholly now markets created. For instance, it v/as discovered in the author's Ip.boratory that it is possi- ble to evaporate viater from juices dovm to 2 per cent moisture content, and when this is done a hard candy-liko substance results .,.».... "Successful hard tablets of conc-^ntrat'id juice, patent for which is now pending, have been made from grapefruit, pineapple, prune, apple, apricot, raspberry ajid other fruits and various combinations of two or more juices. New candy mark'its may be opened, postwar, by the assured surplus of these tablets." Origin of DDT. The much publicized insecticide, DDT, the full name of which is Dichloro-Diphonyl-Trichlorobenzone, v;as first compounded by a young German chemist in 1874 as a routine part of preparing a thesis. No particular at- tention was paid to it until in 1928 when a Sv/iss entomological research company compounded th"-; same material in its search for a pov;erful insecti- cide. Its first practical use vms in tho destruction of an unusual infesta- tion of the Colorado Potato Beetle in 1939 in Switzerland. A bill to prohibit the employment on farms of persons under 14 years of age is said to have been introduced in the Massachusetts Legislature. It al.'^o prohibits persons under 18 from driving a tractor v;ithout first obtaining permission from the Commission of Labor and Industries, Orchard Crowding may b'^ considered as Problem No, 1 in many Massachu- setts orchards. It is closely associated with magnesium deficiency, pest control, and a relatively high percentage of low grade fruit. mrtfjtr.^- m^^m February 15, 1945 Prepared by the Fruit Program Committee of the Extension Service V/.

Farm Work Simplification Do You Know? Killing Chokecherries Just Spray Off the Bark CONTROL OF CYCLAMEN MJTE ON STRAWBERRIES A visit to several strawberry growers last June revealed that cyclamen mite waf present in serious amounts in some of the beds, but was not recog- nized by most grovrers. Because of the difficulty of controlling this pest it is not too early for growers to start planning for it now. This mite, which is light to dark amber in color, lives over winter on the crown of the strawberry plant. It feeds mostly among the young leaves in the growing point and in the unopened flower buds. Infested plants are dwarfed, unproductive and have crumpled, deformed leaves of a bluish cast. Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, Willard A.

The water should be constantly agitated while the plants are being treated and its temperature should not vary more than one degree either way if the mites are to be killed without injury to the plants. Plants should be set as soon as possible after the treatment. Other precautions which will help to prevent the spread of mites from the fruiting bed to the new bed include: 1. Isolating nev/ bed 500 yards or more from other strawberries. 2. Sterilizing tools and containers which have been used in an infested bed, or • allowing them to stand in open air 24 hours before using same in the new bed. 3. Not permitting anyone to go from an infested bed to the new bed the same day without washing hands, changing clothes and otherwise dis- infecting themselves. For the benefit of any who may be interested in selling plants, it is reported from California that plants may safely be shipped after treatment provided that they are cooled, dried to normal condition and packed in moist, sterile moss. — A. P. French SOLE MISREPRESENTATIONS IN TIIE IIURSERY CATALOGUES Human nature being what it is, perhaps one should expect an uninformed public to fall for the ballyhoo of the average nursery catalogue with its beautiful color pictures (frequently of a better looking variety than what the label portrays it to be) and gross misstatements as to the merits of its offerings. Fortunately your State College has long considered the testing of varieties as one of its obligations to all who v;ant reliable information on their behavior in this state. The following varieties are selected for comment as a few of the more flagrant misrepresentations found in nursery catalogues today. Concord Seedless grape - This variety is usually seedless but instead of having a large compact bunch similar to Concord - as it is usually pic- tured - bears a poor, scraggly bunch with berries no larger than small peas. Caco grape - A typical bunch seldom contains more than a dozen ber- ries in spite of the beautiful, large clusters shown in the nursery catalogues. The much advertised August Supreme and Sweet September sweet cherries, according to George Howe of Geneva, New York, "appear to be only worthless Mazzards" as they fruit at that Station. The high priced York Imperial sv^eet cherry appears to be indistin- guishable in tree and fruit from Napoleon. A plant patent was granted to the York Imperial on the basis of its being self-fertile, which fact has not been scientifically established as yet. -3- Dne 1946 nursery catalogue describes the St^^ Regis, an old, mediocre red raspberry, as having very large berries, delicious flavor and bearing TSITtinuously from mid-June until frost. Not one of these statements is cor- r^^ct, but to convince the uninformed customer of the merits of this variety they' show a picture of a cluster of fruits larger than Marcy, of about the color and shape of Taylor, which is mislabeled St, Regis. The price is at least twice what this old so-called everbearer is worth, even in v/ar time. A few other current offerings which, while they may be satisfactory in other parts of the country, have not been found to be so at the State Col- lege, include: Golden Muscat grape, v;hich fails to mature in our short season; Boysenberry, v;hich is not sufficiently winter hardy here; Indian Summer red raspberry, which usually fails to mature its fall crop before freezing weather; Anoka apple, v/hich has very poor color and quality under our conditions. The Beta grape and Hansen's Bush Cherry may be good in extremely cold climates but are of little value v;here the usual varieties and kinds can be grovm. The fact that a variety was originated by a famous plant breeder or that it has been granted a plant patent is no guarantee of its worth. It would seem that it is high time for the nursery industry to take cognizance of the various experiment station reports on varieties and prac- tice a bit of "truth in advertising" lest they kill the goose that lays the golden egg. — A. P. French A LAND-USE PU.TFORM FOR ORCHARDISTS Orchardists are generally conceded to be among the most progressive farmers; perhaps they are tops in this respect. They will doubtless sub- scribe to the following 3-point platform for land use, which v/e have proposed; First, selective land use. This means selecting the best available soil types for a given crop. Since an orchard is a long-time crop and an expen- sive investment, this point is extremely important to the orchardist. Make no mistake in selecting the orchard site. Second, soil improvement. Do whatever is necessary to improve soil productiv- ity. It may mean the use of lime, fertilizer, manure, cover crops, or mulches; it may be the drainage of wet spots. It may be a form of land improvement such as the removal of stone walls in order to give larger and more easily managed orchards. Third, soil conservation. Gains made in soil fertility should be held; that is the object of soil conservation. Orchards in good sod and well-mulched orchards rarely erode except in worn roadways. Contour planting of orchards often makes for easier handling of equipment, checks road erosion in sod or- chards, and general erosion in cultivated, orchards, and conserves moisture. -4- Massachusetts orchardists interested in soil and land improvement and conservation CEinnot afford to overlook the possibilities of the two bills on soil conservation now before the legislature of this state. Both bills offer advantages to orchardists, but an important difference is that one of the bills (H.621) provides a definite procedure for setting up local, farmer- controlled districts for soil improvement and conservation; the other bill (H.777) does not do this. H.621 gives a maximum of local control. — A. B. Beaumont Terraces Hold the YiTater. At the Spur, Texas, Experiment Station two adjacent 10-acre fields were planted to cotton for 12 years. The fields appear nearly flat, but have a slope of six inches per hundred feet. The soils are of the same type. One field has closed, level terraces and is tilled on the contour. The other field is not ter- raced and is tilled up-hill. The average cotton yield from the unter- raced field was 109 pounds per acre, from the terraced field 177 pounds per acre. Value of the extra yield on the terraced field was $7.60 per acre, annually. The terraced field lost no soil or water. The unterraced field lost considerable quantities of soil and 11.5 per cent of all rain. Imagine the problem of a would-be peach grower in Essex County v/hen the expressman delivered (on one of the coldest days last month) a peach tree which had been ordered from a southern nursery, presumably for spring planting. SAInT JOSE SCALE The tremendous increase of San Jose scale in Massachusetts apple or- chards in 1944 is undoubtedly due (l) to favorable biological and climatic conditions, and (2) to changes in pest control practices which encourage a rapid build-up of the scale. The San Jose scale, vifhich hibernates as partly grown nymphs, suffers high vdnter mortality from low temperatures, and several times during the last ten years it has had severe set backs by freezing. Fatal winter tem- peratures for San Jose scale are approximately the same as for peach buds and there was little injury to either scale or peaches in the winter of 1943- 44. ITith a high survival last spring, the abnormally v:arm weather throughout the summer favored maximum reproduction and survival of the young in addition to enabling the development of three or four generations instead of the usual tv;o or three. Yifhen the young crav;lers are born, they crawl over the branches for 1 or 2 days before settling on the bark, and at this time they may be spread from branch to branch or tree to tree by the wind, on the feet of birds, bees, or other large insects. Reproduction is tremendous, and it has been calculated that the progeny from a single female living in the climate of Yfashington, D.C would number 3,216,080,400 by fall if all survived. Normal- ly, parasites keep small infestations of the scale in check but the favorable growth conditions in 1944 permitted the scale to out«distance the parasites. The most effective spray treatment to control San Jose scale is a dor- -5- mant application of a lubricating oil spr^^ dili^ted to contain Z% or more actual oil. In the past, dormant or delayed/applications of oil sprays were made quite regularly, especially in orchards where the European red mite was troublesome. In recent years, oil sprays have been omitted more and more frequently, and the remarkable effectiveness of the summer type of DN sprays and dusts in controlling red mite during the growing season has encouraged this practice. Liquid lime sulfur, even at the summer dilution 1-50, killed many young scales especially when applied at the time the young were hatching, as frequently happened when it was used in a complete scab schedule, letta- ble sulfur and sulfur dust are much less effective and kill many of the predators smd parasites. Outbreaks of San Jose scale in Massachusetts have been sporadic and we may expect that the present infestation v/ill be temporary, but it behooves every fruit grower to nip the current outbreak in the bud by applying a dor- mant or delayed dormant spray containing 2 or 3^o actual oil in 1945. — W. D. Vrtiitcomb YCIY "FRESHLY" HYDRATED LIME FOR SPRAYING PURPOSES? During our meetings with fruit growers, the question is frequently asked, "T/hat is freshly hydrated lime?" or "How long can I keep spray lime and still use it with safety?" To answer these questions, let us first understand how spray limes are made and what changes they undergo when al- lowed to stand for some time afterward. Manufacturers take from the quarry limestone. If agricultural lime or limestone is desired for applying to the soil, they merely grind it up finely. Chemically, limestone is Calcium Carbonate . If, instead, hydrated lime is sought for spraying purposes, they take .the unground limestone and burn it. This process drives off carbon dioxide and leaves just Calcium Oxide, also known as "burnt lime," "hot lime," or "stone lime." This form of lime has a great affinity for water. The manufacturers add water slowly to stone lime, thus slaking it. It takes up the vmter cheraically and is then known as slaked lime or hydrated lime. Chemically, it is Calcium Hydroxide or Calcium Hydrate. It is this form of lime, and this one only, that functions in the spray tank to counter- act arsenical injury and to slow up the undesirable chemical reaction be't\'.'een lime-sulfur and lead arsenate. It has the property of remaining well in (Sus- pension, and it is partially soluble, both of which contribute to its "safening" value. Just as stone lime (Calcium Oxide) has a strong attraction for water, so has hydrated lime a great affinity for carbon dioxide. Just as soon as hydrated lime is exposed to the air, it begins to absorb carbon dioxide from the atmosphere. In doing so, it is changed from Calcium Hj'droxide to Calcium Carbonate. In other words, the spray lime undergoes carbonation and thus eventually changes back to the original carbonate-rock or limestone which was taken from the quarry at the outset. -6- This carbonated line, or limestone, is easily recognized in a bag of lime as a coarse, crumbly layer just beneath the paper container. It does not disperse v/ell in the spray tank. It remains coarse and gritty and readily clogs the gpray nozzles. In addition, it has no value whatso- ever in counteracting spray injury. In fact, chemists have reported that the presence of Calcium Carbonate actually hastens the decomposition of lead arsenate into soluble arsenic. It is also perfectly inert and valueless in the preparation of Bordeaux mixture. If freshly prepared hydrated lime is stored in air-tight containers, it should keep almost indefinitely without becoming carbonated. Y^en stored in paper bags, it is subject to carbonation just in proportion to the extent to which the bag is exposed to the air. If bags of hydrated lime are stored in a large, closely-packed pile or stack, the outside bags will proceed to carbonate gradually while the inner ones should undergo very little carbon- ation even during three or four years of storage. The principal disadvantage of using for spraying purposes hydrated lime that has carbonated slightly is the nozzle trouble and the sludge or settlings in the bottom of the tank. There still would be enough of the calcium hydrate or hydroxide present to act as "safener" if there was only a thin crust or layer of carbonated lime next to the wall of the paper bag. However, it is not always possible to determine through ordinary examination just how far the carbonated lime extends into the package, although it is generally understood that most of it will occur in the outside layer that appears coarse and grainy to the fingers. So, by freshly hydrated lime, we mean lime that vms slaked or hy- drated by the manufacturer v/ithin a year of its use. As a rule, under farm storage conditions, it will undergo considerable carbonation by the end of the first season. If kept over for use the folloviing year, it could be ex- . pected to contain an undesirable amount of carbonated lime. A chemist's analysis should reveal exactly to what extent the hydrated lime has changed to carbonate. — 0. C. Boyd FARIvl WORK SII^LIFICATION Farm workers are scarce and labor is an expensive item in the cost of producing farm products in Massachusetts. It "is quite probable that the farm labor shortage may continue for several years. Faced with this situa- tion, farmers are particularly interested in ways of saving labor and in using the available supply fully and efficiently so as to keep production costs as low as possible. Also, many of the available workers are young and some will be girls and women. Farmers should therefore give considerable thought to ways of making the work as easy as possible. Industry saves money by simplifying work. It has found that the sim- pler and easier each operation is made, the more production results. The principles of work simplification can be, and are being applied to farming. The object is toj -7- 1. Plan the work to make as few jobs as possible. 2. Reduce the motions required for each job to the smallest number. 3. Organize the motions left to require the least possible energy, A 4-Step plan. Farm work simplification principles can be applied to any fann job in four steps. Step 1. Break down the job into all its operations. A Job is a definite, complete piece of work such as spraying trees. An Operation is part of a job. The job of spraying might consist of the~se opera- tions--hauling the sprayer to the water supply, filling the spray- er with water, adding spray materials, travel to the orchard, and applying spray. Step 2. Arialyze each operation, considering questions like these j 1. Can the operation or part of it be left out? 2. Can a substitute way be used? 3. Can two or more operations be done at the same time? 4. Can the order of the work be changed so that fewer operations would be required? 5. Can some tool, device or piece of equipment (perhaps home made) make the work easier? 6. Can extra travel be saved by planning, changing the places where tools, equipment and supplies are kept? 7. Can the operation be made easier by arranging it so both hands can help? Step 3. Develop a new and better way for doing the job which will* 1. Eliminate unnecessary/ operations. 2. Combine two or more operations. 3. Change the order of the operations so that time and labor will be saved. 4. Make possible the use of some tool, equipment or device which will make the work easier, 5. Improve the arrangement of tools, equipment and supplies to save time and effort. 6. Make it possible for the left hand to do as much work as the right hand. Step 4, Apply "the new and improved way for doing the job. In doing some types of work it may take a little time for the worker to become acoustomed to the new method and he may not save much time and ef- fort in the beginning. Hov/ever, by continuing the new method he soon develops new habits. Where distances traveled^are lessened by rearrangement of the order in which work is done, or by placement of tools and equipment the re- sults are obvious. — Roy E.

For every 40 or 50 acres the increase in .production amounts to about a carload per day. J. S. Bailey. That penicillin, the new wonder drug, has been used with unexpectedly good results at the Arizona Experiment Station for treatment of crown gall, sometimes called plant cancer? Crude penicillin treatment may prove valuable in nurseries and elsewhere for the cure of plants on which the tumors are within reach and possibly as a preventive of infection during budding and grafting operations. That since 1940, total farm population in the U.S. has declined 4,700,000? There are now only 25,050,000 people on farms compared to 30,025,000 in 1940 and 32,000,000 in 1933. About 1,650,000 farm folks have gone into the Armed Service, another. 4,650,000 have moved av^ay. Births, however, have ex- ceeded deaths by 1,526,000. That . the suffix "cide," which the dictionaries say signifies killer or destroyer, comes into increasing use as scientists find v/ays of combat-' mg man's pests? Fungicides, insecticides, herbicides, and rodenticides are common examples. That the nitrogen used by crops comes from six sources? They are; (1) The nitrogen content of the soil, (2) Nitrogen fixed by legume bacteria. (3) Nitrogen fixed by non-symbiotic bacteria. (4) Nitrogen supplied by man- ures and crop residues. (5) Nitrogen brought down in rain and snow. (6) Com- mercial nitrogen, \7ith the single exception of commercial nitrogen, the quantity of nitrogen that any crop derives from these various sources can only be estimated. That when 1,000 apple boxes are used the second time, enough wood is saved to crate an aeroplane for shipment overseas J Lletal in 60 wire-bound citrus boxes can supply the nails and straps for crating a jeep for the same journey. That the richest source of Vitamin C of all fruits or vegetables is Black Currant juice? Its content is about three times that of citrus juices. In Massachusetts, however, the planting of black currants is prohibited be- cause of their susceptibility to white pine blister rust. That dried apples v^ere a staple article of trade in early Colonial days? Farmers not only earned money for taxes by drying apples, but exchanged them at the country store for red flannel, coffee, spices and other necessi- ties. ^ In the lumber camps of Michigan this preserved fruit was the culinary delicacy which supplemented many a meal of potatoes, beans and salt pork. -9- That the first large commercial nursery in America vras established by Robert Prince about 1830, at Flushing, Long Island? The Prince catalog of 1794 is said to have contained as many varieties of fruits as some of the present day nursery catalogs, apricots and nectarines being represented by 10 varieties each. The catalog of 1845 enumerated 345 varieties of apples alone. That the Ben Davis variety, because of its splendid keeping quali- ties and attractive color, became knovm among orchardists of the Civil V/ar period as the "mortgage lifter?" In New England, the Baldv/in has performed that service on many a farm and so deserves a well earned claim to the same title. That it was an old-time custom, observed by many people when eating an apple, to select a favorable spot and press the seeds into the ground with a turn of the boot? This may help to account for some of the millions of wild apple trees Virhich dot the New England landscape. That food production in the U.S. has increased fully one-quarter while the number of farms has declined one-tenth? Theodore Schultz, Univer- sity of Chicago Agricultural Economist, believes that by 1950 four million farms in the U.S. will produce a third more food than did the six million farms before the war. That the yield of apples from the Byrd orchards in Virginia in 1942 amounted to 1,200,000 bushels, or about one per cent of the U.S. crop? The Berryville Orchard, with 1500 acres and 70,000 bearing trees, produced about half of this total. The five most important varieties and the percentage of each are as follows: Delicious - 20j York - 16; Stayman - 16; Rome Beauty - 14; T/inesap - 12. That wild blackberry plants growing near peach orchards provide win- ter quarters for strawberry leafroller worms which in turn are hosts to the beneficial Macrocentrus ancylivorous, parasite enemy of the Oriental fruit moth? Vfe are not yet ready to recommend encouraging the wild blackberry, however, because of other problems v/hich might arise. That the United Stateis now has 5,282 frozen-food locker plants? In Iowa, v/hich has the most, there are 580 plants. Minnesota is second with 470, and \Tashington State is third v;ith 404. Last year's increase was 723 new plants, not counting additions to old ones or plants still under con- struction. That Florida now has an estimated 377,450 acres of bearing citrus groves, with about 6000 acres a year of nevir acreage coming into bearing? present groves consist of 251,340 acres of oranges, 95,190 of grapefruit, 23,420 of tangerines and 7500 of limes. That the fruit juice pack for the whole U.S., including Hawaii, in 1935, was 9,317,000 caaes v^hile in 1943 it was 39,202,000 cases? The packs of the various juicea were about as follov/s: grapefruit - 20^029,. 700; pineapple - 8,600,000; orange 2,702,000; other citrus juices and concentrates - 2,789,000; grape * 1,500,000; apple - 1,000,000; nectars and miscellaneous juices - 1,000,000; and prune - 450,000 cases. .10- That if the national apple crop were to be distributed equitably throughout the nation, every nan, woman and child would receive about a bushel? With many people eating five or even ten bushels each year, it is easy to estimate hovi few apples others, particularly in non-apple produce. ing sections, are consuming. . That a sweet apple is sweet not because it contains more sugar than a sour apple, but because it contains less acid? J. K. Shaw Killing Chokecherries. The sodium chlorate and more recently the ammoniura sulfamate sprays for killing chokecherries and other vieeds have become war casualties. Although there is hope of getting some sul- famate next spring, the supply will probably be limited at best. Therefore, growers would be wise to keep an eye on the new 2-4-D sprays. Reports in- dicate they are effective against chokecherries. Hovrever, they are still in the experimental stage. J. S. Bailey. 1945 APPLE SPRAY CHART. .?roof of the new chart has been returned .'to. the printer. This is considerably earlier than in sev- eral years past. The new charts may be ready for distribution by the time this issue of Fruit Notes is received. Just Spray Off the Bark, An article under this heading appears in a recent issue of Food For Victory VJ'ith King Apple, from Illinois. Victor W. Kelley, Extension Horticulturist, reports a new method of removing rough bark from apple trees, as follows: "Scraping off rough and loose bark in a codling moth sanitation program is a very tedious and slow process. A more efficient method is to spray it off. Use a standard spray gun with a No. 8 disc (8/64 inch aperture), and apply water at 500 pound pressure, A mature apple tree 25 to 30 years of age may be thoroughly smoothed off in four to five minutes. Small trees may be so treated in one minute or less. The procedure is simple, but certain precautions should be observed, Work about two to four feet distant from the tree trunk. Hold the gun at a 45° angle when cleaning out around the bottom of the tree, or too much of the crown will be exposed to low temperatures if spraying is done during the early winter. Adjust the gun when necessary to prevent injury to live bark, "Spraying off the loose and rough bark has the following advantages over hand-scraping: (1) It is three to four times faster, including the time required for filling; the tank and hauling, and requires only about the time of a regular spray application. (2) It is more thorough in crotches, punky areas, et cetera. (3) It destroys a high percentage of over-wintering larvae. (4) It is possible to reach higher branches, (5) No new equipment is necessary. In view of the labor shortage not many grov;ers will be able to hand-scrape this coming year. Certainly every grov;er should be able to spray off the bark and be prepared to band in 1945," March 8, 1945 Prepared by the Fruit Program Committee of the Extension Service yj, H.

The rate of water loss from apples in an average storage is such that toward the end of the season the fruits have lost from 3 to 5%, While apples seldom shrivel in storage^ there is only a small margin of safety and when displayed by retailers in a warm dry room, shrivelling occurs rapidly. The grower or storage operator has no control over conditions in the food store. He can, however, and ought to store fruits in such a majiner that they lose a minimum of water by the time of sale to the retailer so that they can withstand further loss before shrivelling. Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, Vfillard A. Munson, Director, Massa*husetts State College, United States Department of Agriculture, and County Extension Services cooperating. -2- The rate of water loss depends on the nature of fruit itself and environmental conditions. The skin prevents free evaporation and is respon- sible for the fact that a free water surface of the same area loses 30 to 50 tines as much water. The skin is not absolutely tight. Vifater vapor es- capes through lenticels, called commonly dots, and through the cuticle between the lonticels. About 4 to 10 times as much v/ater is lost through the cuticle as through the lenticels, V/hen apples are placed in storage their rate of water loss steadily decreases for some time even if they are placed under constant environmental conditions. This is due to a number of factors, chiefly to the increase of wax or bloom on the surface of the skin, to closing down of lenticels, and to dessication of the skin. The grower has some control over natural tendencies, so far as water loss is concerned. Too early or too late picking may make the fruits more susceptible to shrivelling. Washing or brushing for spray residue removal may remove the surface wax and increase greatly the rate of water loss. It is, however, by controlling conditions during the storage period that the most satisfactory prevention of shrivelling can be accomplished. In order to keep v/ater losses down, the temperature in the storage must be low (31°F to 32°F) and relative humidity high (8&% to 90^). These two conditions are being achieved by sound engineering devices and good pomological practices. The engineer provides storage with adequate collage to remove field heat from the fruit quickly. He will also try to maintain a minimum differencial between the temperature of the refrigerant and that of the room in order to avoid taking too much moisture from the at* mosphere in the form of frost deposits on the pipes. The grower's first effort should be directed toward immediate stor- age of the fruit. The disastrous effects of delayed storage are too well known to need discussion here. There are, however, some other considerations that are not as clearly realized. Among them is the problem of the package, Apple boxes are made of wood v^hich is highly hygroscopic material. Very of- ten they are stored over the summer in hot sheds, packing houses or garrets where they dry up considerably. Y/hen such dry boxes are filled with fruit and taken into the storage, they absorb moisture from the storage atmosphere and from the fruit. A dry New England apple box may absorb over half a pound of water in storage, A heavy field box weighing about 12 pounds may absorb nearly 3 pounds of water as shown by v/eighing experiments conducted this winter at Rhode Island State College. In the same experiment, it was found that during the first 6 weeks of storage, apples in dry boxes lost on the average almost 3 times as much water as apple* stored in wet boxes. It is true, of course, that these boxes were exceptionally heavy, but many farm storages use rather heavy boxes. It is clear that the condition of the boxes may influence v;ater loss of apples and thus tho time of shrivelling. It is therefore recommended that -3- and boxes be stored in a rather cool and moist place during the summer ,/^hat they be exposed to rain and dew in the orchard or cool shade before harvest time. Soaking them by turning on the hose may be helpful. In the old days when apples were stored in tight barrels, shrivel- ling was no problem. Our modern apples boxes, open for ventilation, favor a high rate of v>rater loss. Anything that makes the box tight will decrease lo3i of moisture and delay shrivelling. Shredded oiled paper, wrappers and liners of all kinds serve the same purpose. One hundred and twenty five special boxes were built at Rhode Island State College and compared vfith standard boxes made of the same viood. Special boxes differed from standard New England boxes in that they were tight. There were no slits at the bot- tom and there was a solid cover. It v/as found that moisture loss was 30^ higher in standard boxes when compared with the tight boxes. YIa.r imposed restrictions do not allov; us to uee many of the new things that would improve keeping of the fruit. Two developments offer con- siderable promise: Waxing and vapor-proof ceXbphane liners and wrappers. Both already play a very important role in the citrus and vegetable indus- tries. (The foregoing review of an important subject vms prepared for Fruit Notes by Di". S. A. Pieniazek, Rhode Island State College.) TREATI.ffilJT FOR BORON DEFICIEIJCY Probably the most dependable treatment for boron deficiency (inter- nal cork) in apples is a soil application of borax in a narrow ring under the tips of the branches. Suggested amounts to supply per tree are from 2 to 16 ounces depending on tree size, (For example, a tree with a trunk diameter of 3-^- inches shpuld have about 2 ounces; 7 inches - 6 ounces; 14 inches - 8 to 12 ounces; etc.) According to Dr. A. B. Burrell of Cor- nell University, where soil applications are repeated at 3-year intervals as recommended, it seems desirable to reduce the amount per tree by one-r third at the second application, and probably by one-half at the third, ■ The question has been raised concerning the possibility of applying borax by adding it to one or more of the regular sprays. In Canada, spraj^ applica tions have been recommended for orchards on high-lime soils, and in New York and New Hampshire borax has been included in sprays on an experi- mental basis. In New Hampshire, large amounts of borax v;ere used v/ithout causing injury to apple foliage but in New York some injury resulted where high calcium-lime yras not included in.. the spray raixtur«, A suggested pro- cedure is to include borax at the rate of 2 pounds per lOD gallons in two spray applications - possibly the first and second cover sprays. Unless the deficiency of boron is severe, this treatment should provide protection against the occurrence of internal cork in apples. It has been shown that an application of borax to the soil lasts about three years. In some cases, protection from a single application may be had for a longer period but it is hardly safe to rely on this possibility. Thus, it is suggested that any orchard v;hich has shown evidence of boron de- ficiency and to which borax has not been applied for three or more years should be treated this season. Soil applications of borax are recommended but spray applications \vill probably be satisfactory, — Lav/rence Southwick -4- COID STORAGE OF STRAY/BERRY PLAIITS It is generally agreed that there is no better strawberry plant than the well grown local product. However, much of the hajidicap of plants from the Middle Atlantic States (due to differences in season) may be overcome with proper handling. It has been found in New York State that plants dug at the proper time (March in the Middle Atlantic States) shipped north immediately and held in cold storage until planting time in the Worth produce a better stand, earlier growth and earlier runner development than plants shipped at the right time for planting in the North. Good apple cold storage conditions are ideal for such strawberry plants, i.e., 28°-34° F. and 855^-90^ relative humidity. The package of plants should be examined on arrival to make sure that they are moist. 'If not, sprinkle them but do not soak the packing material as that may cut off air circulation. Plants need not be removed from the bundles while in cold storage, but make certain that they neither dry out nor that the temper- ature gets high enough to permit grovrth to start. — A. P. French FURTHER C ORIENTS ON NURSERY PRACTICES Since last month's outburst against the unethical practioos of some nurserymen, a few more items worthy of comment have come to mind. 1. True-to-name Peach Varieties. It is true that peaches, as well as other tree fruits, are examined for mixtures in the nursery row. However, since it is impossible to positively identify all peach varieties in the nursery row the inspection work with peaches is on a much less certain basis than that with other tree fruits. This fact is annually called to the atten- tion of all nurserymen who avail themselves of this service • Yet several of them have so worded their catalogues as to give the impression that their peaches are as positively true to name as are their other tree fruits. 2. Method of Propagation. From the fruit grovrer's standpoint it makes little difference whether air~apple tree is propagated by budding or by graft- ing using piece root, whole root or an "old-hickory" method, nor does it matter much Vvrhere they are grown. An individual nurseryman adopts a par- ticular practice because that practice produces the most good nursery trees under his conditions. Thus, a dozen Mcintosh trees of equal size from as many sources and methods of propagation, will probably do equally well in the orchard, regardless of the nurseryman's claims. 3. Bud Sports and Superior Strains. That there are strains of some var- ieties, especially "color strains, is an established fact, but unfortunately most of these cannot be identified as different than the parent form in the nursery rov;. Furthermore, there are probably more strains listed by nursery- men than are actually recognized as distinctly different strains. One nur- sery's Super Crimson Red Mcintosh may be the same thing or no better than another concern's Double Red Mcintosh. The fruit differences between many of these strains have not been definitely established as yet. -5- 4. Renaming. The superlatives and coined words used by some nurserymen as a part of the names of their varieties is bad enough, but when a nursery- man deliberhtely renames a variety, it is just plain fraud. Fortunately, such cases are in the minority, but several have occurred in the past few years. 5. Substitution. One of the most unethical practices of still too large a number of nurserymen is that of substitution. Fortunately, this is practiced less on the commercial fruit grower than on the amateur, but any substitution is too much. YJhether a person orders 100 Fredonia grape vines or only one he is entitled to receive what he ordero.. He doesn't want the nurseryman to send him a Moore's Early and tell him that it is just as good as Fredonia. Even the average amateur knows as much as the average nurseryman about the merits, defects and adaptability of varieties in his location. Far v/orse than acknowledged substitution is the common practice of deliberately re-labeling varieties to fit the order. Some nurserymen care little about having their pears, plums, and sweet cherries inspected for trueness-to-name, because "they mostly go out in small orders anyway," mean- ing that the most important consideration when filling small orders is to accept the customer's money and send him something. One local amateur after getting mislabeled tress from three apparently reputable nursery concerns asked in disgust, "Aren't there any honest people in the nursery business?" — A. P. French FERTILIZER NEEDS OF ORCHARD TREES Recommendation of the proper fertilizer applications for orchards is difficult. There can be no doubt that nitrogen is needed in most orchards, but the need of other elements is often in doubt. We have learned that many orchards need magnesium, and boron deficiences have been found. There are probably a few orchards that need potash. Proof of need for other elements in Massachusetts orchards has not been established, but such may exist. These statements refer to immediate benefits to the trees. There may be indirect benefits from a "complete fertilizer" and also lime. These will build up organic matter in the soil. If sulfur sprays and dusts increase soil acidity so that the pH is around 5 or lower, it must be bad for the trees. Some orchardists use only nitrogen; others a complete fertilizer. This difference in practice is obviously not closely related to differences in orchard conditions. There is little money wasted in buying nitrogen, but how much of the extra cost for phosphorus and potash comes back to the grower by increased returns for his crop? Perhaps somo growers profit from a com- plete fertilizer while others do not. How can vife toll which is which? There is increasing evidence that a chemical analysis of the leaves may prove the most dependable basis for making fertilizer recommendations. Some progress has been made toward establishing minimum percentages of the different elements. Trees having a lov/er content are likely to show a char- acteristic leaf scorch or other evidence of a deficiency. It may well be that trees suffer from too little magnesium or potassium before leaf scorch is evident. An analysis of the leaves might enable the orchardist to prevent the leaf scorch rather than cure it. This would be a great advantage, es- pecially with magnesium deficiency which is slow of correction. -6- It is premature to state the minimum content of mineral elements in leaves, but they •vrill be somewhere near this; Nitrogen 2%; Phosphorus 0.15^; Potassium 1%; Calcium 1%', Magnesium 0.2^ of the dry matter. There will be a border zone around these percentages indicating that trees may or may not be suffering from a deficiency; but if they are well above, the grower may well save his money. The v;-riter has made many foolish statements regarding orchard ferti- lization in the past 40 years, and one more may do little harm. So here goes I The next generation of fruit growers will rely largely on a chemical analysis of the leaf for determining his orchard fertilizer program. Let future years show whether this is another foolish statement. — J. K. Shaw grot; VEGETABLES AS ViTELL AS FRUITS Home vegetable gardens are a wartime necessity. They are a vital part of the nation's food production program. The farm labor situation is so tight that regular farmers the nation over will be hard put to reach the food production of the past few years. That means that home gardens must again produce a good share of our vegetable supply. In 1944 these home gar- dens produced over 40^ of the fresh vegetables. Every family, with good land available, should play safe and grov/ their own in 1945. Following is a list of leaflets which are free to residents of Massachusetts.

Late March is an ideal time to prune grapevines for at lea's't three reasons; (1) The snow will have set- tled enough (we hope) to expose the entire vine. (2) If winter in- jury has occurred it should be apparent by that time. (3) The vine is not inclined to "bleed." A good job of pruning and 2 or 3 well timed sprays or dusts may mean the difference between a highly sat- is factory and a disappointing crop of grapes.

DN dormant sprays should be applied before the green tip stage of the buds. Varieties of apples which break their buds quickly, such as Gravenstein, Yel- low Transparent, and Duchess should be sprayed first. 7, V'/here dormant DN and oil are combined, the amount of oil and dormant DN is generally reduced to decrease possible injury to buds.

On Mcintosh which is seldom attacked by rosy aphis, a 3 or 4jo diluted oil spray to control scale and red mite is the most practical dormant treatment. LO. On Cortland, which is very susceptible to rosy aphis, a DN dormant spray with- out oil to control aphis, followed by a DN summer spray or dust to control red mite, if necessary, is suggested. If both scale and aphis are serious on Cortland, the risk of injury from DN-oil spray, must be taken. LI. DN 111 spray and DN D-4 dust are dinitro products for summer use and should not be confused with Elgetol or DN powders for dormant sprays. L2. Bud moth, fruit tree leaf roller, apple red bug, and other scale insects are also controlled by dormant sprays. •^ — YL D. Ymitcomb RABBIT INJURY IN FRUIT TREES Many of us are more concerned than usual about the injury to our or- chards from rabbits this winter. The combination of a deep covering of snow and an unusually large population of "Cotton-Tail" rabbits has set the stage in many orchards for serious rabbit injury. A brief review of my experiences in controlling rabbits in my own or- chards may be helpful to some readers of "Fruit Notes." About five years ago, we set an orchard of about a thousand apple trees, mostly one year whips. This orchard is divided by stone walls into several blocks and has brushy pasture land and woods near it. These are ideal conditions for harboring rabbits. On the second day after planting, we knew we had a problem on our hands v/hen we found quite a few of our one-year whips cut off about a foot above the ground. The injury was greatest near the outside of the orchards and new evidence of rabbit snipping was found for several weeks, although it was worst just after planting time. That summer we made plans to protect the young trees as it was a sure bet there would be a lot of injury the following winter if nothing was done. Several repellents, to be applied either as a paint or a spray, were available. IVe chose a repellent which is made by dissolving 7 pounds of rosin in 1 gallon of industrial alcohol, and applied it with a small paint brush. This combin- ation of materials proved to be ,safe for the trees and was used several years -9- with good results. In fact, we decided after the first year's experience to apply the solution to all young trees immediately after they were set. Vfe had a girl follow the planter and treat each tree. As the trees became Isirger, the job of painting the trunk and branches to a height of at least three feet, became quite a chore. This past fall found us behind on our v/ork, and hired help was as scarce as "hen's teeth." It seemed that the job of painting all those trees would be impossible. So we decided to try trapping the rabbits to lessen the possibility of injury. After this winter's experience with box traps I am convinced that at last we have found a method we should have chosen at least tv;o years ago. Trap- ping and removal of rabbits is eliminating the source of trouble whereas painting with repellents only delays it. In my estimation, the repellents should be considered only as an emergency measure to give protection until such time as more effective steps can be taken. You will be interested to note that I have caught 17 "Cotton-Tails" so far this winter. Most of them have come from the brush areas on my farm. Out of all the young trees which vie now have, I do not think we could find more than a dozen trees which have been injured by rabbits this v/inter. The amount of injury is quite different in several other orchards where no control measures have been practiced, or where trapping was started late. In one orchard where there are apple and pear trees of different ages, there has been very serious damage to both apple and pear trees. Whole young trees have been eaten off to the snov/ level and on many trees six to eight years old, the bark has been removed on large areas of the trunks and main limbs. I have seen older bearing trees where the rabbits have made a clean job of removing the fruit sp'urs within reach. Eleven rabbits have been re- moved from this orchard so far, and there are still a few more to be caught. The trapping of rabbits is very simple and can be done after the rush of the fall season is over. Apples make ideal bait; some people say sweet varieties are preferred although I doubt if it makes much difference if they are sweet or slightly acid. Cold nights following a moderately heavy snow- fall seem to be ideal for catching rabbits. One can make his own traps at little or no expense except for the labor required. It should not take more than an hour to build a trap. The necessary odds and ends can be found on most farms. There are many designs of box traps. The type made by using boards for the top and bottom and small mesh poultry netting for the sides and back is most desirable. A trap 10" or 12" square, and 18" to 24" long is large enough. The trigger arrangement for closing the door is the one feature which has received most attention. (Any grower interested in the details of construction may obtain them by dropping a line to the writer, French Hall, M.S.C, Amherst, Mass.) Just a word of caution. AH rabbits caught must be reported to the State Department of Conservation, Div. of Fisheries and Game, Boston, Mass., giving the number of rabbits taken and disposition of the same. — A. C. Ballard .10- C OBSTRUCTION AND HANDLING OF THE BRUSH DRAG A brush drag which will save considerable time and labor in hauling brush from the orchard can be constructed from heavy hog fencing. Th» drag is constructed by tying together three 18 to 20' sections of "No. 9^ wire" hog fencing. The., sections are tied together by weaving a piece of heavy wire, such as telephone wire, around the outside wire of each section. Three sections of hog fencing will make a drag about 9 feet wide. Attach a log 9 to 12" in diameter to each end of the drag. A short chain is fastened around the middle of each log, so the drag can be hauled from either end. Brush can be easily piled on this type of drag, and it will have a full load at about the time the pile is too high to load easily. The real saving in time and labor comes in unloading the drag. A long 3/4" rope is tied to the rear end of the drag and brought up over the load and hitched to the tractor. Unhitch the drag from the tractor and start up with the rope hitch. The load of brush will then be rolled up into a compact pile, and the drag will be pulled free and clear of the brush pile. This drag will slide along quite easily on a heavy frozen sod, but it may bog down if the orchard is very muddy, and of course it may get hung up on stubs or similar obstructions between the tree rows. However, these disadvantages are offset by the ease with which the drag is loaded and un- loaded when compared to a truck or wagon. Telephone wire wmmm^ >v Hog fencing Chain — W. D. Vfeeks New Mimeographed Circulars. A new publication on Brush Pushers will soon be available. Sketches and copy were submitted for mimeographing a few days ago. For those individuals living in towns where the growing of currants and goose- berries is permitted, a new mimeographed circular on that subject will also be of interest. How Soil Thaws, It is not very generally known that the thawing of a frozen soil in spring proceeds more rapidly from below than from above. In a thoro^^gh study of the effects of various ground covers on freezing and thawing, as com- pared with a bare soil in Kansas, soil heat was found to be about 3 times as efficient as that of the air, in reducing the thickness of the frozen layer. •11- VARIETIES OF CULTIVATED BUJEBERRIE3 FOR tlASSACHUSETTS Although the blueberry variety list is short, the variety question, nevertheless, is an important one. Since new varieties are being introduced fairly rapidly, a periodic reappraisal of the variety situation is necessary. Cabot, ipioneer, and Rubel have for a number of years been the three most s'atis"factory varieties and are still the most favored by Massachusetts grow- ers. Cabot is the earliest of the three. It usually starts to ripen the second week in July. The bushes are relatively low, usually not over 4 to 4r^ feet high, spreading, and only moderately vigorous. Also, the bush is very susceptible to a disease called Phomopsis gall, which looks like crown gall, and is somewhat subject to winter injury. The fruit is rather taste- less and not the best blue, but the size is good and yields are good. The berries usually crack badly after rains and drop badly if they become over- ripe. Earliness, especially for the roadside stand, is the most important advantage of this variety. Pioneer is a midseason variety. The bush is a little taller than Cabot, equally spreading, and slightly more vigorous. Because of its habit of growth, it requires more detailed pruning than other varieties. The ber- ries are a good blue, large when v/ell grown, very fine flavored, and good keepers. Unfortunately, yields are only light to moderate. For general planting it is the best of the midseason varieties. P.ubel, the latest of these three, is the most desirable for all around planting. The bush is tall, upright, vigorous, very productive, and resistant to winter injury. The fruit has more flavor than Cabot but is not so good as Pioneer. The berries are only medium in size, but their color is good and they ship well. It is the easiest of the three to propagate. Jersey, one of the newer varieties, is well worth a trial both by the commercial grower and the home gardener. The bush is tall, upright, vigorous, productive., easy to propagate and prune, and resistant to vdnter injury. The fruit is large, very atox active and very fine flavored when fully ripe. It colors before it is fully ripe so that care must be taken not to pick it too soon, else it will be soui'. The stems are long, making picking easy. It ripens with Rubel, Lut the picking season is not so long. It does not sprout from the base as freely a:5 is desirable.- Concord, a midseason variety, ripening v/ith Pioneer, is well worth a trial on~C^.f;~reavTer poil.s of the northern and western parts of the state where it gr'^vj-^ and yrelds yrell. It is not recciT-.iierded for southeastern Massa- chusetts where it d-^s.s r.ot thrive on the light, 3f.n.'y sc\ls. On. the soils where it thrives the buE^'3s are tall, upright, vigorous, and productive. The fruit is Jarge and very "^.ttrautive but not quite so fint flavor^.d a.s Pioneer. The fruit clusters arc tight and the berries hanr, bo the stom well so tiiat the first picking or two is not so easy as with a long-rt-^nrcod vp.riety like Jersey. There is a 3li,^ht tendency for the skin to t-;a:- in picking. These are both serious disadvantages from a commercial strmdpoint. The fruit ripens with Rubel. Atlantic , a new variety ripening with Rubel, sesras worthy of trial, AlthougTn.t has not yet fruited at Amherst, the fruit is said to be much larger, better colored, and finer flavored than that of Rubel. Burlington, -12- another new variety which has not yet been fruited at Ajnherst, seems worthy of trail. It is said to b'? somewhat later than Jersey and Rubel and has un- usually good keeping quality. The fruit is above average in dessert quality, .^ an attractive blue, and medium to large size. The bush is upright, vigorous, and moderately productive. To sum up, pioneer, Rubel, and Jersey are the best commercial varieties. 'Cabot is recommended only where an early variety is especially desired. Concord is a~"nidseason variety recommended only for the heavier soils of the northern and v^estern parts of the state. Pemberton, Atlantic, and Burlin[;ton are prom- ising but are recommended for trial oniy.""" Since blueberry varieties are to- tally or partly self sterile, two or more varieties need to be planted together. I — J. S.

If the weather is dry during that period, or if it is characterized by several short wet periods, even a heavy carry over of scab would be of lit- tle consequence. Short periods of wetting servo to release scab ascospores but do not permit infections. If at that timo, however, prolonged wet per- Issued by the Extension Service in furtherance of Acts of May 5 and June 30, 1914, V/illard A. Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. -2- iods occur, even a slight eunount of inoculum in the orchard is likely to prove hazardous. At present, many orchards in the state show a heavier carry over of the scab fungus than usual, for the reason that some growers "let up" on spraying last summer when the season was dry. As one result, there develop- ed more storage scab last winter than has been seen for several years. Another result is an abundance of old, spotted leaves in the orchard liter- ally loaded with ripe ascospores ready to "shoot" during the next rain, Scab spore development in the old leaves is as far advanced as fruit bud development. Heavy discharges will occur in all orchards during the next few wet periods. Hence, the pre-blossom sprays of sulfur are likely to be vejy important on scab-susceptible varieties. With the season so far advanced, long, cool, damp periods are likely to be encountered before blooip, and certaiftf^^ttal-f all. Special considera- tion might well be given to the prospective need of dusters (or sprayers in the absence of dusters) during rainy periods. This holds true especially during the blossom period when spore dissemination for both scab and the ce- dar rusts reaches its peak. Infection Periods to Date. - So far (April 11) there has been only one infection period for apple scab. The rains on April 2 and 3 furnished an intermittent wet period of about 22 hours in jimherst at an average temperature of around 56° F. Although this was longer than necessary for infection to occur at that temperature, the spore discharge was very light. Fruit buds were betvreen delayed dormant and pre-pink. Only a very light infection is expected from that wetting. The next rain on April 4-5 caused a heavier spore discharge, but the 15 hour period of wetting was too short to allow scab infection at the prevailing temperature of about 43° F. It was during that rain, with fruit buds in early pre-pink, that cedar-apple rust spore horns first underwent gelatinization and discharged spores. The first spore- shower from quince rust cankers is yet to come, but it will occur during the next rain. — 0. C. Boyd PASTE SULFUR m THE SPRAY IIIG SCHEDULE Paste sulfur has been both praised and condemned. It has been praised for its excellent fungicidal properties and scab control; condemned because it is difficult to handle. Paste sulfur is the finest particle sulfur of the wet- table sulfurs, and in this respect comes closest to the spray residue result- ing from liquid lime sulfur; but, in contrast to the liquid, paste sulfur em- bodies all of the safe features of the mild or dry wettable sulfurs. Paste sulfurs derived from the gas production industry contain from 40-50^ active sulfur. The balance is essentially water. ?/ith the inherent advantage of extremely small particle size, paste should be used at no more than 10 lbs. to 100 gallons of water, and this maximum amount should be limited to the early critical sprays. For the finishing off applications toward the end of the season, the amount can be reduced to 5 lbs. Thus, in -3- the interval the amount of paste should be lovrered in steps from 10 to 5 lbs, to 100 gallons of water. The handling of paste in practice should not be cumbersome. Handling is simplified by marking off on a pail the volumes corresponding to the weights of paste desired; i.e. 10, 20, 30 lbs,, etc. Accuracy is not too important since 1 or 2 pounds more or less to the tank would be of no consequence. The traditional user of dry materials will find nothing cumbersome in the handling •of paste sulfur, once he has acquired the routine of its use. Once the barrel of paste is opened, water should be added to prevent drying. Drying destroys the fine particle state of paste and converts the material into grit. The paste should be kept covered with a little water at all times to prevent this change. Sulfur paste should not be added directly to the spray taink. It should be diluted in a pail with a little water and made into a thin soup, then poured through the screen in the tank. This pro» cedure is important to avoid "gumming up" the intake strainer in the bottom of the tank, or clogging the spray nozzles. Combined sulfur and lead arsenate is generally not advisable on Red Delicious, Starking, and Baldwin varieties due to the russet injury to the apples from the combination. Paste sulfur offers no exception. Russet can be avoided on these varieties by substituting Fermate for sulfur, particularly in the "pink," "Calyx," "First and Second Covei" applications. Paste sulfur offers some means of economizing in materials, but its chief merit is its fineness and its fungicidal efficiency, the latter being one of the major objectives in plugging up the loop holes or weaknesses in our ap- ple spraying program, — E. F. Guba AN EARLY SPRING The spring of 1945 is by far the earliest in many years. April weather in March started growth and on April 2 apple trees were about as far advanced as they were a month later in 1944. The average date of full bloom of Mcintosh in the College orchards is about May 14. The buds are now (April 12) in the Pink stage and will be in full bloom in a very few days if the present warm weather continues, or about a month ahead of the average and two weeks ahead of any previous record. The cold morning of April 7 (27°p.) was a narrow escape from disaster. Five degrees colder would have cleaned out the crop. The av- erage minimum temperature for April at Amherst is 22° and for May it is 31,2°, If a temperature of 2 or 3 degrees belov/ the May average occurs later this year, it v/ill cause great damage. If we get by this spring it will be almost a miracle. Our native fruits are able to withstand the following temperatures for 30 minutes or less.

A 17-year-old unfertilized peach orchard in Davis, California, v;as. fertilized in September with ammonium sulfate, calcium nitrate, and urea. The soil and trees were studied during the vdnter and early spring to learn hov/ the nitrogen from these three sources behaved in the soil and in the trees, itamonium sulfate was fixed in the soil more than the other forms of nitrogen, but nitrates had gone down as far as the third foot by February 27. Analysis of the shoot bark on March 7 showed the nitrogen content in- creased over that of unfertilized trees. The source of the nitrogen made lit- tle difference. This was also true of the nitrogen content of the leaves which were first examined on April 10. This is in harmony with the usual belief that under most conditions fruit trees will maJce about equally good use of nitrogen from various sources. (Proc. Amer. Soc. for Hort. Sci., Vol. 45, page 5). — J. K. Shaiv VfARMING THINGS UP. You have doubtless noticed that snow melts more quickly on a black tar road than on a lighter colored cement road. This is because a dark surface absorbs more heat from the S'lm. Observations in New Hampshire show that the inner bark on the south side of a fruit tree may rise to 60° F. or more on a cold winter day, while that of the north side may be 30° to 50° F. lower. Painting the trunks white resulted in much lower temperatures, at no tine more than 10° above that of the air. At night or on cloudy days, there was little difference in bark temperature. If we have sunny weather during a January thaw, peach buds vdll swell much more than \vhen the v;eather is cloudy. (Proo. Amer. Soc. Hort. Sci., Vol. 45, page 33) — J. K. Shaw WAX SPRAYS FOR BLOSSOM THINNING. There is considerable interest in the use of sprays for blossom thinning. Hand thinning is laborious and, with prospects of labor shortage, anything that will save labor is of interest. The Michigan Experiment Station proposed to use an oil-wax emulsion for this purpose. It was first used to reduce transpiration and thus economize water in dry periods. A 1/0 concentration used in the regular sprays gave a marked increase in the size and yield of Montmorency cherries. Used as a blossom thinning spray, it seemed to be somewhat effective but more work is needed to determine whether it is entirely satisfactory. It does not injure the foliage as does Elgetol or a Dormant DN spray. We hope to try the oil-wax emulsion this season and be able to report on its effectiveness under our conditions. (Proc, Amer. Soc. Hort. Sci., Vol. 45, page 42). — J. K. Shaw ELGETOL KILLS POLLEN GRAIIJS Elgetol used for blossom thinning kills the pis- tils and other parts of the flower; also, it burns the young leaves to some extent. Of course, killing the pistil before fertilization of the egg cell prevents setting of the fruit. V/ork at the Cornell Station shows that Elgetol also kills pollen grains before or after germination even in very dilmtte con- centrations. Therefore, they say that Elgetol should be called a "pollenicide" not a "caustic spray." However, bees may sometimes bring viable pollen from -5- unsprayed trees. If the pistil is killed before the pollen tube has grown doimward far enough to escape the toxic effects of' the spray, no fruit cam be set. It still seens that pistil killing is an important factor in blos- som thinning. They recommend that a 2-day period between pollination and fertilization of the egg cell is enough to insure set of the apple. It will, of course, depend on temperature. If the weather is cool, it will take long- er than in warmer weather. (Proc . Amer. Soc. Hort. Sci., Vol. 45, page 53.) — J. K. Shaw BLOSSCM THINNING YJITH ELGETQL In Virginia, 33-year-old York Imperial trees which were quite defi- nitely in alternate bearing were sprayed with Elgetol in concentrations of from approximately one to three pints in 100 gallons of spray. A concentra- tion of a little under 2 pints gave the best results on this variety. On thinned trees, there was some reduction in the percentage of N.umber One apples on account of roughness, stippen on oversize apples, etc., but no color dif- ferences were apparent in the harvested fruit. T/ith stronger concentrations, size of fruits increased and total yields decreased. (Proc. Amer. Soc. Hort, Sci., Vol. 45, page 45). —J. K. Shaw. FURTHER TESTS WITH BLOSSai THIMING MTERIAI3 . Tests of the effectiveness of various materials for reducing TEe set of Delicious, Gano, Staynan, and Arkansas Black apples were made in 1942 and 1943 in New Mexico. Elgetol re- duced set but caused considerable injury. The chemicals commonly used to make apples stick to the trees in the fall were also tried. It may seem foolish to expect such a chemical to make apples drop in the spring, but we know that a high nitrogen fertilizer maJces apples stick in the spring and also may in- crease drop in the fall. ¥/hen these materials were used in strong concentra- tions, the set of fruit was practically eliminated. Napthalene acetic acid, the active principle in many preharvest sprays, used at very weak concentra- tions, thinned the fruit successfully and did not cause severe injury. Cer- tain chemicals related to napthalene acetic acid were not effective. Borax at ,h% and \% concentrations reduced set without visible injury. These ma- terials are not yet recommended for thinning apples, but further study may show a way to reduce set without injury such as that caused by Elgetol. (Proc. Amer. Soc. for Hort. Sci., Vol. 45, page 63). —J. K. Shaw. Hew Bulletin. A nevi bulletin in the series on the identification of fruit varieties by vegetative rather than fruit characteristics has been written by Lavn-ence Southwick, A. P. French, and 0. C. Roberts of the Pomology staff. It is expected that this Experiment Station Bulletin No. 421 will be available for general distributicn by the time this copy of Fruit Notes is received. The title is ''The Identi- fication of Pear Varieties from Non-Bearing Trees." Special con- sideration is given to the characteristics by which nursery pear trees may be identified. Descriptions and photogrcphs of some 40 varieties are given. As with other Station or Extension ''oulletinfi, copij" will be sent to those requesting them. -6- WINTER KILLING OF RED RASPBERRIES In spite of the continual snovi cover during the past winter, there is considerably more winter killing of canes in the College plantation this spring than a year ago. The canes of many varieties are entirely dead above the snow line . A three-year average shows that Chief, Lathajn, and Indian Summer are the most Iwinter hardy, showing only about 10^ killingj next come Taylor, Ranere and Sunrise with about 20^^ killing} and Milton with about 40^o killing; vihile Cuthbert, Marcy and Nev;burgh show from 65-70^'o killing. Unfortunately, some of the most winter hardy varieties have other v/eaknesses. Indian Summer fails to mature its fall crop, Taylor is serious- ly damaged by mosaic vihen present, and Sunrise is inferior in size and quality.

The way some of these trees are handled at planting time and afterward is a horticultural crime. They should be made to grow rapidly from the start and not allowed to loaf along the first season. A "leader" should be encouraged by removing entirely or cutting back any competing branches. V/horls of branches and forks should be corrected promptly. Even more important than the pruning at planting time are the corrective cuts during the second and third years. If delayed until tlie tree is four or five years old, larger cuts' are necessary and an ideal framework is, in many cases, out of the question. Let's give those young trees the attention they need this spring. NITROGEN CONTENT Of APPLE l£AVE5 There seems to be a close relationship betv:een the amount of nitrogen in apple jp.eaves in late summer and the color of the fruit. The optimum nitro- gen content is probably slightly under 2%. In one orchard where the fruit was of good color the nitrogen content v/as found to average 1.8^. Ij^ another or- chard where the fruit was of poor color the nitrogen content was 2.1^. It is a well known fact that over vigorous trees tend to have dark green leaves which are indicative of a fairly high nitrogen content v;hile trees with lighter colored leaves may bear fruit of high color. In years to come we will probably analyze apple leaves in late summer as one check on the nitrogen needs of the tree. This will help to supplement our present knov/ledge of the factors re- sponsible for fruit of inferior quality. Fruit Notes Mailing List. Mailing lists for all of the M.S.C.

Here are a fev; conunents heard at a recent meeting in Worcester: "V^e have too maiiy green Mcintosh." "I'd rather have 2^ inch red Mcintosh than 3 inch green ones." "\'/hen we get the right kind of fruit, we can get a good price, but 75jb of the Mcintosh in storage are too green and soft." With thousands of bushels of green Mcintosh still to be sold, growers and dealers alike are asking "V/hat's happened to Mcintosh?" "V/hat are the reasons for sp high a percentage of green apples in certain orchards?" This is the subject of a detailed statement which has been preparod by the mem- bers of the Pomology Department at M.S.C, to be sent to every interested apple grower in Massachusetts. Any reader of Fruit Notes who fails to receive a copy of this analysis of an important problem within the next two or three weeks may obtain it by dropping a postcard to ViT. R. Cole, Secretary,- M.F.G. A. , Amherst, Mass, Among the reasons for poor color outlined in the above mentioned statement are (1) Too much nitrogen in late summer. (2) Fruit immature, (3) Magnesium deficiency, (4) Boron deficiencAr, . (5) Trees too crowded. (6) Inadequate pruning. (7) Yfeather conditioniMiay affect all these factors and increase the tendency toward oversize fruit, delayed maturity, poor color, and early drop. In answer to the question, "Should nitrogen applications be discon- tinued?" we should bear.. in mind that nitrogen starvation reduces yield and tends to throw even Mcintosh trees into biennial bearing. It is advisable, of course, to maintain a good sod cover in the orchard. This calls for mag- nesium limestone Euad a "complete" fertilizer in moderate amounts broadcast on the grass at intervals varying with soil conditions. The remedy for too much nitrogen in the tree is less nitrogen, not more phosphorus or potassium. There are several things which the apple grower may do to reduce the percentage of green Mcintosh. He may (1) Adjust the nitrogen application to fit the orchard. (2) Correct magnes-ium deficiency. (3) Correct boron defi- ciency. (4) Allow apples to reach reasonable maturity before harvesting. (5) Remove crowding trees. (6) Grade out and dispose of green Mcintosh in the fall, if possible, instead of trying to hold them in cold storage. The State College will cooperate in a further study of the green Mcintosh problem. From a list of orchards which persistently produce green, inferior quality Mcintosh, a number of orchards will be selected for a care- ful analysis of the factors which may be responsible. Other orchards which produce firm, high colored Mcintosh will provide a basis for comparison. A detailed report of this study will be presented at the annual meeting of fruit growers in Vforoester next wiAter. Hew Seedling Apple. Vfe have a few one-year trees of a promising seed- ling apple called A-17, developed here at the College, for trial dis- tributioia to interested growers. It is an early apple, ripening in late August. A few trees wore distributed last year. Anyone wishing to test this seedling may contact the writer at Massachusetts State College, indicating the number of trees desired, — Lawrence Southwick, -8- CORRECTION OF MAGNESIUM DEFICIENCY Magnesium deficiency is rather widespread in apple orchards. In some oases ^ definite symptoms such as leaf scorch, early defoliation and excessive preharvest drop have been observed. In others, clear-cut symptoms have not been noticed. It is probably true that many orchard soils in the Northeast are close to the deficiency level for many plants, including apple trees. For this reason, the general orchard use of high magnesium limestone is recommended, except where the soil acidity is already up to pH 6, or above. One other recommendation that could be follov/ed rather generally is the in- clusion of Epsom salts in one spray application. The use of 15 pounds of Epsom saltis in either the First or Second Cover spray might help to tide trees over a slight magnesium shortage situation. For definitely deficient orchards, further measures are advisedi The above recommendations refer to "borderline" cases, where definite deficiency symptoms have not yet appeared. — Lav/renoe Sbuthwick ORCHARD HEATING The old idea that a smudge or smoke screen will ward off a frost has boen disproved. Frost damage in an orchard is prevented only by actually raising the temperature of the air above the danger point. Many small fires, viell distributed, are much more effective than a fev/ large ones which might merely serve to set up heavy convection currents and thus bring in a flood of cold air from the surrounding country. One large fire, as for example a burning brush pile alongside the orchard, is likely to be of little if any benefit. Only an occasional grower in Massachusetts will probably find it possible to equip himself v;ith the necessary containers and fuel for orchard heating this spring. As a matter of insurance, in case the temperature drops only a degree or two below the critical point, even as few as 10 or 15 con- tainers per acre may be worthwhile. One grower who has done considerable orchard heating believes that approximately 25 containers per acre are neces- sary Vfhere a severe freeze is involved. He has used paint pails holding two or more gallons and has actually raised the temperature of the orchard air as much as 6 degrees above that of the surrounding territory. Ordinary fuel oil was usQd» Y/aste crankcase oil has the disadvantage of boiling over be- cause of its water oontont. Anyone who plans to try orchard heating this year must of necessity provide himself with one or more strategically lo- cated thermometers which are accurate within a degree at least. The next item of importance is to make sure that the heaters are lighted shortly be- fore the temperature drops to the danger point. PENICILLIN- LIKE SUBSTAI^[CE FOUND IN LEAVES AND FRUITS. Research workers at Michigan "State College have discovered" germ-killing substances in the fruits of blueberry, currant, mountain ash said honeysuckle, and in the leaves of the Scotch thistle, mullein and peony. Negative results were obtained from horseradish, turnip, and cabbage. These discoveries suggest that the Indian medicine man and other users of plant extracts, poultices, etc. may be ahead of their time. • 9- Pistil. Green if uninjured, Brown if injured by frost.

APPLE BLOSSOM Frost Injury to Flowers or Young Fruits If a frost comes, every fruit grower will want to know hov/ much damage has been done. Since time must elapse for injured tissues to wann up and change their appearance, the full amount of the damage may not be apparent until afternoon or even the follov;ing day, depending on the tem- perature. During blossoraingj the pistil is the part most easily hurt. The normal pistil is light clear greon in color. Injured pistils first look waterSoaked, then discolorod and wilted, and finally turn brown, shrivel and die. Since normal pistils, following fertilization of the ovary, turn brown, shrivel and die, this normal condition should not be confused v;ith frost injury. When the young fruits have formed, the seeds are usually the most tender. Normal seeds turn brown or black. ViTith apples the tissue just out- side tlie seed cavity is sometimes injured. Although apples v/ith injured seeds sometimes set, such apples are small or misshapen at maturity. Those injured outside the seed cavity seldom mature. Sometimes the injury takes the form of a loosened layer of cells around the small undeveloped fruit and upper part of the stem. With peaches, the veins around the seed are the most sensitive, then the seed and finally the flesh. The skin of a young fruit which is badly injured by frost, turns yellovf and the fruit drops in a few days. If injured only to the extent of a slight slipping of the skin, the fruit may mature although it will show russeting or frost cracks at harvest time. -10- Young fruit Pistil. Green if uninjured.

Up to the present (May 21), there have been eight general infection periods in the State since apple trees v/ere in the late de- layed dormant stage of fruit bud development. Not only have rainy periods been niomerous, but the total precipitation has been excessive. For example, the total rainfall in Amherst during April v;as 5.43 inches, or 2.08 inches above normal; and for May (up to the 21st), 5,97 inches, which represents 2.37 inches above normal for the entire month. The following are the dates of apple scab infection periods for unsprayed Mcintosh trees at Amherst and the dates when the scab spots appeared on the new leaves j Date of Rain April 2 April 17-18 April 25-26 April 30-May 1 May 3-5 Tree Stage Pre-pre-pink Early bloom Late bloom Calyx Calyx Scab Spots Appeared April 29-30 May 11-12 May 13-14 May 16-18 May 18-20 Issued by the Extension Service in furtherance of Acts of May 5 and June 30, 1914, Willard A.

C. Boyd TEIvlPERATURE RELATIONSHIPS FOR APPLE STORAGE ROTS A study of apple storage rots in the state of ViTashington revealed 40 species of fungi to be associated with loss of apples in cold storage. Only about a dozen rots are of common occurrence in Massachusetts apple storages. Although all organisms able to bring about the decay of apples at cold stor- age temperatures will cause more rapid decay at higher temperatures, certain fungi are able to cause definite decays in ordinary storages but are totally inactive in cold storage. An examination of some of the literature dealing with apple storage decays reveals the following classification of storage rot organisms according to their relationship to temperature. 1. Fungi unable to cause decay in cold storage but capable of causing rapid decay in conmon storage and on the markets RhiZopus nigricans (the Bread Mold Fimgus); Phoma sp., cause of Phoma Rot. 2. Fungi unable to cause decay at cold storage temperatures but able to cause spot rots at higher temperatures: Glomerella cingulata, the cause of Bitter Rot, is a typical example. It does not make progress at temperatures below 50° F. The disease is common in a few orchards in the southeastern part of this state. Helminthosporium papulosum, cause of Black Pox Rot, and Myco- sphaerella pomi (Brooks' Spot or New Hampshire Fruitf are other examples. 3. Fungi causing spot rots in cold storage but more rapid decay at higher temperatures: Volutella fructi (Spongy Dry Rot) ; Alternaria spp. (Alternaria Rot); phoma sp. (Phoma Rot); Gloeosporium sp, (Anthracnose Rot, which is sim- ilar in appearance to Bitter Rot but behaves entirely differently at cold storage temperatures); Physalospora cydoniae (common Black Rot); and Venturia inequalis (Scab). 4. Organisms capable of causing complete rotting of apples during their usual storage life in cold storage: Mucor piriformis (Mucor Rot); Penicillium expansum (Blue Mold Rot); Botrytis spp. (Gray Mold Rot); Physalospora cydoniae (ordinary Black Rot), i The storage rots most common in Massachusetts and also the ones that develop most rapidly in cold storage are Blue Mold Rot, Gray Mold Rot, and Black Rot. All make definite headway at 32° F. By comparison. Scab and Spongy Dry Rot develop very slowly. —0. C. Boyd 7» CO f 0. 3 '^ s (^ y 9 7 fd 1/ J2 f3 /y- ^^/'' '7 /f /?

If held two or three weeks at that temperature, they ripen gradually and are just right for canning. But if kept warmer (80 to 100°) ripening is not hastened and the pears remain tough and poor flavored when cooked. Stored below 50°, they do not soften and are not good when cooked. That one kind of orchid, a native of Mexico, is grown for its fruit and not for its flower? This fruit provides the most important flavoring substance which the jimericans have contributed to the world. Its name is Vanilla planifolia. That the 1944 peach crop (75,000,000 bu.) will go down in history as the most valuable crop of that fruit ever produced? It had a farm value of $171,677,000, 56^ above the most valuable crop previously grown (1943). The 1944 crop was exceeded only once (in 1931), when the average price per bushel was 60 cents. The farm price in 1944 was |2.33 per bushel. That Massachusetts offers a market for over $100,000,000 worth of farm products annually? These products are now grown on 30,000 farms, covering 400,000 acres of cultivated land. About 1,750,000,000 lbs. of food are produced annually in Massachusetts, filling Zb% of the needs of our people. That most of the grapes grown on the Pacific Coast are of European origin? They were first plaiited by Franciscan missionaries as early as 1769, One vine growing in California is said to have borne 15 tons of grapes in a single season. That fully 20^ of all America's crop production is the result of using fertilizers? In 1938, each dollar spent by the farmer for fertili- zers produced a return of $3.60 in crop value increase. The return at present is estimated at more than $5,00 per dollar invested. That a method of loading bees v;ith suitable pollen is being used successfully in Missouri? Pollen of early blooming varieties of apples is screened out and stored at 32 to 40° F. until time for placing a quarter of an ounce in a beehive fitted with a device which insures ingress to the worker bee at one point and egress at another. Once loaded with the pollen, the bees cannot crawl back into the hive at the same point. Hence, they go out to seek noctar among the late blossoms thus cross pollinating reluc- tant varieties like V/inesap and Stayman. That heavy fruiting of the Delicious variety of apple may require an average terminal growth of 12 to 15 inches? The ideal seems to involve 40 to 60^ of the spurs blooming, with only one blossom in ten setting fruit. -7- That the aoute labor shortage has brought about the invention of mechanical arms for use in California citrus groves? A machine-powered tent puller covers citrus trees with canvas to form a fumigation chamber into vj-hich a gas is released to kill destructive insects. About 80 such pullers are now in use. That 8 infection periods for apple scab had occurred in Massachu- setts up to May 207 By that date new scab spots had appeared on apple leaves from the first fivB infections, April 2, 17, 25, 30, and May 3. That some strawberry plantings in the Falmouth area show severe damage from the hurricane of last September? A shov/er bath of salt water from tlie ocean killed enough plants in exposed areas to cause considerable crop reduction. That Japanese beetles were trapped last year in 18 states outside of those already under federal quarantine? An excellent publication, "The Jap- anese Beetle and Its Control" (Farmers' Bulletin No. 1856), v.dth an illus- tration of the insect in color, is available. That nicotine has been synthosized in the laboratory? But the pros- pects for its comiiiercial manufacture are not bright. Rotenone and the py- rethrins have such complicated structures that there is little hope of their synthesis in the laboratory, much less on a commercial scale. That German War Prisoners wore used last fall in the Nashoba area by 75 growers, 3 cold storage plants, axid 2 cider and vinegar plants? They furnished a total of 17,747 man days of labor, picked 349,551 bushels of fruit on a piece work basis and worked 31,988 hours on an hourly basis. That at least 18 products are now produced commercially from apples? Among them are: Fresh sliced, canned, evaporated, sauce, frozen, nuggets, juice, vinegar, pectin, v/ax, syrup, concentrate, brandy, win^, boiled cider, and malic acid. That the codling moth population reached an all time peak in east- era U. S. last year? One of the reasons suggested is the present heavy production of Mcintosh, an annual bearing variety which is very attractive to this pest. That the lists of new fruits published by the American Pomological Society during the past 20 years contain 3,705 names? Apples lead with 754 names, followed by peaches, 601; strawberries, 371; plums, 336; grapes, 331; pears, 238; cherries, 155; raspberries, 153; apricots, 133, etc. That activated charcoal is being used successfully as a means of pre- venting scald of apples in storage? Air conditioning of the storage room is accomplished by means of canisters with sieve-like sides lined with brom- inated charcoal through which air is drawn by a suction fan. That, according to federal entomologists, about eight million flowers are visited for each pound of pollen gathered by honey bees? A strong col- ony may gather approximately 65 pounds of pollen annually, thus providing froe pollination service for 520,000,000 blossoms. Ihat the Oriental fruit moth first appeared in California in 1942? Every state in the Union, except North Dakota, now has this pest or is bor- dered by another state which is infested^ That quinces may be protected against Oriental fruit moth by bagging? Tihere only a few fruits are involved, this method of enclosing each individ- ual fruit in a paper bag insures freedom from attack by this troublesome insect. PEACH CROP PROSPECTS AT THE COLLEGE. The prospect for a crop in the Col- lege peach orchard looks much brighter than it did a week ago. During the past few warm days the little peaohee have started to swell, giving an in- dication that some blossoms have survived the frost and poor pollinating weather. Examination after the frost revealed that l/S to 1/2 the blossoms had been actually killed. However, the ovaries of uninjured blossoms failed to swell so that it looked as if fertilization had failod to take place. It is now evident that in many oases failure to swell was due to the cold weath- er. Of course, it will not be possible to make any accurate crop prediction until after the June drop, but prgsent indications are for a fair to good crop on many trees and some crop on most trees, — J. S. Bailey THE BUJEBERRY CROP AT THE COLLEGE. During the winter of 1944-45, there was severe injury to the blueberry bushes but not as bad as during the winter of 1943-44, As a result of the winter injury, the crop was undoubtedly reduced to a fourth of what it should have been. The April 23 frost also reduced the crop slightly. All open blossoms and some nearly open were killed. For- tunately, very few blossoms were open at the time so that the crop reduction amounted to 5, or at most, 10 percent. It looks now as if the crop would be about 1300 quarts, which is double last year's. — J. S. Bailey HERE'S AN IDEA. Assuming three things - (1) a crov/ded orchard, from which the owner intended to remove the oxtra trees but de- cided to leave them "one more year," (2) a crop destroyed by frost, and (3) a little spare time resulting from a shortened spray schedule, wo make this proposal j That every other diag- onal row be removed now (before June 15) to give the remaining trees the advantage of more light and mineral elements this summer, thereby putting them in much better condition for the 1946 crop. \I June 28, 1945 Prepared by the Fruit Program Committee of the Extension Sej-vice V/.

Strawberry plants, too, will be placed under more rigid inspection, especially for Cyclamen Mite and Red Stele. Both of these pests are poten- tially serious and both are present in the state. The program for better planting stock involves the full cooperation of the State College for the information it can supply, the State Department of Agriculture for a well informed and rigid inspection service, and nursery- men themselves for a real desire to improve and expand the industry. — R. A. Van Meter SOIL TYPE AFFECTS MCINTOSH COLOR Most fruit growers in Massachusetts have received the leaflet on the Green Mcintosh Problem published by the Massachusetts Fruit Growers' Association. This was necessarily brief and did not elaborate on many as- pects of the problem. The bad effect of high nitrogen in late summer was emphasized. No mention was made of the relation of soil tj'pe to high ni- trogen. It is easy to over-supply trees growing on the heavier soils which we commonly regard as having rather high fertility while the lighter soils rarely get too much nitrogen. These lighter soils are well drained and well aerated, so they usually lose any excess of nitrogen in the drainage water, and the nitrogen-containing organic matter is so rapidly oxidized that no great reserve of nitrogen accumulates. In late summer the nitrogen supply of the tree is therefore sufficiently depleted to permt earlier maturity and better colored fruit. It is on the more fertile soils, retentive of moisture, that we get most of the green, immature apples, — J. K. Shaw VfflY SOME APPLES DO NOT SELL It must be a painful experience for anybody who loves good apples to visit the chain stores and many other places where fruit and vegetables are exposed for sale. The contrast between apples on one hand and citrus fruits and vegetables on the other is humiliating. Oranges present an at- tractive appearance and in most cases are as good as they look. Most veg- etables are fresh and attractive. Even green tomatoes are artificially ripened eind packed in cartons. They all appeal to the eye and deplete the pocketbook. But most of the apples on display repel possible buyers and properly belong in the cull pile; yet the price is enough to warrant decent quality. Many think that such apples should not be allowed in the market place. Certainly they are not worth the price asked. Unless something is done about this situation, Ihe apple business is on the way to the abode of sinners, V/e have talked about it a lot. liYhy not do something about it? — J. K. Shaw -3- A HODEICT V/ITCHES ' BREW The fruit grower of the future may have in his vraod shed a shelf on which will be a collection of bottles containing various brews from v^ich he v/ill select the proper ones and spray them on his trees; Then he will be free to attend the dog races (?) until harvest time, when he will come home and harvest a big crop Df perfect, red apples which he will sell at $10.00 per box, and then be in a position to replenish his supply of magic concoc- tions and resume his life of ease and enjoyment. This may be a bit exaggerated, but hovif is this for a starter? — A material . which promises to accomplish all of these things; (1) serve as a blossom thinning spray, (2) prevent excessive fruit bud formation, (3) delay blossoming until after frost danger has passed and extend the harvest period of Mcintosh, (4) prevent premature drop of the fruit, (5) solve the green Mcintosh problem by turning the apples yellow in two weeks' time, and (5) serve as a killer of unwanted weeds. These varied effects are brought about by varying the concentration and time of application. This, too, may be a wee bit stretched, but all these varied uses are within the realm of possi- bility. You will hear more of this story in the near future. — J. K. Shaw PICKIIIG FRUIT (Some general suggestions from work simplification studies) 1. Arrange the job so that both hands can work. Equal use of both hands usually increases output by about 4:0% over using one hand alone. 2« Keep both hands together for greater hand-eye coordination. The eyes cannot direct both hands if the hands reach out in opposite directions. 3. Fill the hajids full ''^fore moving them to the container. On hand har- vest jobs as much as 70^ of the picking time is spent in moving (trans-, porting) the fruit from the tree to the picking container. By getting the hands as full as possible, this transport time is reduced. 4. Keep picking container - basket, bag or pail - as near the hands as possible. By keeping the container conveniently located with respect to the hands, transport time and extra steps can be reduced. 6. Use a picking container adapted to the job. For apple picking, a light- weight picking bucket of full-box capacity attached to the worker with comfortable harness speeds up the job and makes it easier. 6. Approach any hand harvest job in an orderly fashion. ViHien picking fruit (apples, peaches) from the ground, pick the highest fruit first so that the decreasing weight on the branches will not cause the fruit to spring out of reach. Size up a tree before setting the ladder to pick the tree with a minimum number of ladder moves. 7. Simplify the task of removing the harvested crop from the field. Have adequate field roads. Y/here possible, locate the boxes at frequent in- tervals so that the filled picking containers do not have to be carried long distances. -4- 8. Give inexperienced workers clear, complete instructions on how you want the job done. Indicate who is to be responsible for each job and in- struct him in his specific responsibilities, — Roy E. Moser COST OF FSRTILITY Each year thousands of tons of plant nutrients are lost from Massachu- setts soils through erosion. Some of this is by physical erosion, plainly visible to the discerning eye; some by invisible erosion which only the chem- ist can detect. To plug the hole caused by current losses and to restore deficiencies created through years of exploitative farming, farmers in this state each year use thousands of tons of fertilizer, lime, and manure, cost- ing millions of dollars. According to a recent bulletin issued by the Massachusetts Experiment Station, another record was made in the use of soil amendments in this state in 1944, 89,837 tons of mixed fertilizers, fertilizer materials and chemi- cals, and commercial pulverized animal manures were used. This amount is slightly higher than that for the preceding year. In addition, Massachusetts farmers annually apply between 50,000 and 60,000 tons of ground limestone and more thaji a million tons of animal manures, and plow under between 30,000 and 40,000 acres of green manure crops, all of which have a total money value between |6, 000, 000 and $7,000,000, With this great investment in materials and labor for soil improve- ment, it is only common sense to protect the investment by conserving the improved soils. Losses through water erosion, wind erosion and to some ex- tent chemical erosion, can be totally prevented or reduced by following such conservation practices as cover cropping, contour fanning, strip cropping, and terracing. Conservation practices conserve moisture as well as soil and fertilizer. Increase in yields of 10 to 15 percent may be expected from the adoption of conservation methods, — A. B. Beaumont FROST AND THE PREVENTION OF FROST DAMAGE. This is the title of Farmers' Bulletin No. 1588 which may be obtained from the State College, Midsummer is an unusual time to talk about frost prevention but it is none too early to begin preparing for next spring. Any grower interested in a readable discussion of this important subject should obtain a copy of the above pub- lication, and become familiar with the fundamental principles. MAY AND JUNE RAINFALL IN AMHERST. Rainfall in May amounted to 6,45 inches and in June (up to the 25th) 7,53 inches. The normal for the two months is 3,6 and 3,75 respectively. Some rain fell on 17 of the first 24 days in June, If one were planning the weather for apple scab infection he couldn't improve on what the weather man has given us in 1945, -5- LB^ That, except for size, the apple maggot and the blueberry maggot are even more alike than so-called identical twins? In all stages of de- velopment, egg, larva, pupa, and adult, according to F. H. Lathrop, Maine Entomologist, the blueberry maggot is two-thirds as large as the apple maggot. If the former is transferred to an apple it is able to attain full development, while an apple maggot may require two or three blueberries. This raises the question whether or not a large fruited variety of cultivated blueberry may provide a suitable food supply for the apple maggot even though the wild blueberry can support only the smaller strain of this insect. That, under certain weather conditions, fire blight may be trans- mitted by the wind? Although insects have long been considered as the sole disseminating agents, recent experiments have shown that the bacteria may ooze out in the form of long, slender, gelatinous filaments which dry into hair-like strands and are broken off and blown away. Just how far the strands may be blown, how long the bacteria remain alive, and how import- ant these structures are in the spread of the disease have not been determined. That Mcintosh twig growth has in some cases been killed by apple scab? According to Donald Folsom, Maine Plant Pathologist, "The only way to prevent scab infection of the new twig growth is to keep the twigs covered with a fungicide until midsummer, when the elongation has stopped and the bark has reached a certain stage of maturity. Sulphur dust has proved somewhat better than other fungicides." That the Golden Jubilee of the Delicious apple is being celebrated this year and the Elberta peach has now reached its 75th birthday? If, accord- ing to J. K. Shaw, 50 years are required for an apple variety to justify it- self, the Cortland will be on trial for a few more years. The original Ben Davia x Mcintosh cross was made in 1898 but the seedling did not fruit until 1906 and was not generally introduced until 1915. This variety fruited for the first time in the College orchard during the early 20's. That a definite relation exists between the color of apple leaves in late summer and the nitrogen content of the tree? Since the supply of ni- trogen in late summer has a definite bearing on fruit color, it is reason- able to assume that apple growers will in future years become more conscious of the shade of green in the leaves as an indicator of the nitrogen needs the* following spring. That the Food and Drug Administration has adopted a tolerance of DDT on fruits similar to that of lead and fluorine? On the basis of available data there is general agreement that DDT is not more toxic than either lead or fluorine. The informal tolerance for lead on apples and pears is 7 milli- grams per 2,2 pounds. -6- That in Colonial times 90 out of every 100 people in this country- had to work on farms to grow enough food? Today the ratio is just reversed. Then one man could take care of about five acres of corn. Now he can handle 100 acres. In 1909 it required 12.7 man hours to grow an acre of wheat. Today it takes 3.3 man hours. Despite this progress many farmers are still under equipped for the 1945 job. To say that some fruit grov;ers are working under the handicap of ajitiquated equipment is a mild understatement. That a fertilizer application may show an effect for at least 8 years? in Missouri a section of a prairie meadow was fertilized in 1936 by top dress» ing with various commercial fertilizers in amounts up to 600 pounds per acre. Each year since that time the hay from the fertilized areaa and from an un- fertilized check area has been cut ani stacked separately. Cows have been allowed to feed on those stacks which were most attractive. Up to 1944 they invariably fed on the hay from fertilized areas and even after that date they chose to visit the fertilized areas v/here they found the pasturage more attractive. In an orchard there is reason to believe that the grass result- ing from a broadcast application of a complete fertilizer exerts an in- direct benefit on the trees over a period of at least 10 years. That two fruit crops unknown in this country 40 years ago were con- sumed in large quantities in 1944? An avocado crop of 23,200 tons from Florida and California, and a grapefruit crop of 56,020,000 boxes v/ere in- cluded in the nation's diet. David Fairchild, veteraji plant explorer, in looking back over his 40 years of studying and introducing fruits and veg- etables from all parts of the world, recalls clearly the early prejudice and resistance against these fmiits at the time of their introduction. That 200 tons of citrus pomace will be put up this year at a plant in Florida? Apple growers supplying the pomace market may expect real compe- tition from citrus fruits after the war. The citrus product seems to be especially suitable for msiking marmalades, jellies and gelatin desserts. That the light set of Delicious, commonly reported by apple growers, may be due in some cases to a peculiarity in the structure of the Delicious blossoms. R. H. Roberts, Vifisconsin Horticulturist, says, "It was observed that a peculiarity of the Delicious blossom structure permits honeybees to extract the nectar without pollinating the blossoms. This was true in ap- proximately 80^ of the bee visits this season." His observations seem to indicate that honeybees are able to obtain the nectar without actually con- tacting the anthers and stigmas. That the light crop of apples throughout the Northeast is due as much if not more to faulty pollination as to frost injury in the blossoms? A. B. Burrell, New York State plant Pathologist, reporting from Essex County, says, "\'/hi 3e freezing injury to blossom buds v;as severe, pollination appears to have been a still more important factor in limiting the set. In many cases, the favorable effect of the trees of a suitable pollinizer variety, is restrict- ed largely to adjacent Mcintosh trees, the second tree away beiiig conspic- uously light. It is the first time we .have seen this extreme localization of pollination," -7- SSEN Airo HEARD IN MAIIJE It was the writer's privilege to spend the week of June 11 attending a series of orchard tours and twilight meetings in Maine. Follopfing are a few random observations j Oyster shell scale. In several orchards this insect has assumed the role of a major pest. The eggs were just hatching and the young scale insects were settling down in enormous numbers particularly along the base of the current season's growth. Twig killing was observed in two orchards. A nicotine spray timed sifter the eggs had hatched should prove quite effective this year since the hatching period was shorter than in years past. An experiment with Sumraer DN and other materials is under way. Moose damage. In one young orchard in Monmouth, invaded by a moose last spring, brov;sing vms observed up to a height of about 8 feet. Deer are also causing much damage and growers are seeking relief in the form of hunting permits, 15 of which may be granted for an individual orchard. Crop prospects. Maine growers suffered less damage from frost than was first repoirted. The apple crop promises to be about half normal. Of the orchards visited several showed a 75fo set while others were much lower. The May snowstorm caused much breakage. One grower said he spent two days hauling brush out of the orchard after the storm. Apple scab. Con- ditions are very similar to those in Massachusetts. May and June have been very rainy and some scab is shov/ing up in most orchards. A heavy infection was observed in certain orchards ivhere too few sprays were ap- plied. One grower obtained good scab control with four dusts and one spray. Magnesium deficiency. Most growers are applying epsom salts as a spray. V/here this material is used in combination v/ith lime sulfur a heavy black sludge is observed. There is a growing tendency' to use wet- table sulfur or sulfur dust instead of lime sulfur. CONTROL OF ORIENTAL FRUIT MOTH Owing to war conditions, it was impossible to carry through the pro- gram of rearing Maorocentrus parasites for Massachusetts growers. Because of labor shortage and the interruption of normal transportation facilities, it is doubtful v^hether the program can be resumed until the termination of the war. Recent experiments indicate that the sulfur-oil-talc dust (which is available commercially) or a nicotine-bentonite spray such as Black Lfjaf 155 at 3 pounds to 100 gallons of water shows promise indiecking the pest. The recommended schedule calls for four applications at 5-day intervals beginning three weeks before harvest. — A. I.

That classic remark of Mark Twain'*s was never truer than this year. However, since the v;eather is such a vital factor in farming and every farmer must be interested in it whether he likes it or not, a few remarks on the cussedness of the present season should not be out of place.

May June July months Aug. 1 Normal T761 3.19 3.70 10.50 3.35 3.60 3.75 4.10 14.80 25.30 1945 3.07 3.33 2.16 8.56 5.43 6.45 7.67 7.36 26.91 35.47 During the first three months of the year precipitation was prac- tically two inches below normal. In April the heavens opened and have been "pouring it on" ever since. Tho excess for April through July has been 12.11 inches, making the excess for the seven months of 1945 10.17 inchos. This heavy rainfall, together with hot, humid weather during June and July, has made the control of many diseases on both fruits and vegetables very difficult. This has been the worst apple scab season in years. Orchards which vrero not frequently and thoroughly sprayed are heavily infected. Also carry- over for next year will be heavy. Brovm rot of peaches and plums has been severe, particularly on susceptible varieties. The mummy berry disease of blueberries, a very close relative of the brovm rot of peaches and plums, has been unusually severe on both wild and cultivated berries. Because of this disease and the depredations by birds, tho College blueberry crop will be far belovf early estimates. A good raspberry crop was in prospect but tho repeated rains caused many berries to mold on the bushes or to become soft and v/orthless. Several unusually heavy rains during June and July have made insect control more difficult by washing off arsenicals soon after they were applied. This has been especially true of codling moth control during July. Because of the light crop and abundant moisture apples are sizing up more rapidly than nonnal. The prospect is for many over sized ones of poor keeping quality. — J. S. Bailey KILL THE CHOKECHERRIES If you are growing peaches and don't want the X-Disease, get rid of the chokecherries . Novj- is a good time to do it with a weed killing spray. The X-disease, or Yellow-Red Virosis, is a virus disease which spreads read- ily from chokecherry to peach but not so easily from peach to peach. There- fore it is very important to eliminate all chokecherries within 200 feet of a peach orchard. The chokecherry is a very persistent thing and will sprout from any pieces of root left in the ground. Attempts to get rid of it by mowing or digging are ineffective. The surest means is a weed killing spray. New weed sprays have been put on the market recently and mtHI probably bo made available next year. Although several of these are being tried at the College, it is too early to draw any conclusions. From past oxporience, tho t^z-po of material containing ammonium sulfamato appears to be most ef- fective. It should bo used according to the manufacturer's directions, — J. S. Bailey -3- THE POISON IVY PROBLEM AND ITS SOLUTION Poison ivy need not be tolerated in orchards now that adequate neans for killing it out are available. Every year many orchard workers are af- fected in varying degrees from minor localized irritation to serious poison- ing requiring doctoring and hospitalization as a result of being poisoned by this obnoxious plant. Incidentally, poisoning talces place only by direct contact. When poison ivj' is established under and on fruit trees, it is very difficult to harvest the fruit without coming in contact with the ivy. And for persons viho are susceptible to ivy poisoning, it is rather foolhardy to take a chance. Considering the scarcity of harvest labor, it is very much to the advantage of fruit growers to exterminate the ivy in order to elim- inate this cause of picker dissatisfaction. Several materials, usually to be applied as sprays, can be used for this purpose. In orchards at the Massachusetts State College and in a number of commercial orchards j, poison ivy has been treated successfully with ommoniiim sulfamate. One application in midsumner has usually killed most of the ivy but often there is partial and spotty recovery tho folloif/ing season. A follow-up application the second year should be made v^herever ivy is present; othenvise, it may again bee ">me vigorously established. There are other ma- terials, such as the complicated new "hormone" chemical known as 2-4-D, which are promising. In any case, chemical sprays should be applied preferably on Tfarm sunny days and while the ivy is gr'Tn'v'ing ivell. Following tho applica- tion, no further measures need be taken at least until the following season when some recovery may or may not show up. Care should be taken not to get the spray on the foliage of the fruit trees, --Lav^Arence Southwick WHY POOR APPLE QUALITY? A study of the defects causing poor apple quality ivas made by the New York State College of Agriculture, Department of Agricultural Economics, from data collected at a fruit auction and at retail stores. Surface bruis- ing was by far the most prevalent defect. In fact, practically every lot saiapled contained bruised fruit. This emphasizes the vital importance of handling apples r/ith utmost care from the tree to the consumer. Lack of good color was the second most frequently observed defect vdth tv;o-thirds of the lots failing to meet color standards. Apple scab, stem punctures, and codling moth stings were each evident in one-half or more of the lots sampled. Red bug stints, russeting, leaf roller injury, limb rub, and dirtiness caused somewhat less severe damage. (From Farm Economics, Hay 1945.) — Lavifrence Southwick APPLE MAGGOT FLY EIjERGENCE. The peak of emergence in the ITaltham cages occurred on July 19, according ■to y;. D. T/liitcomb. By that time 75^ of the expected total of flies had appeared. ^^•^ INCREASE IN APPLE PRICE FOR THE EAST (From July 28 issue of The New York Packer) The ceiling price of fresh apples during the period beginning July 21 and ending August 19 will continue to be $3.45 a bushel, f.o.b. shipping point, but in all states east of Ohio, Kentucky, Tennessee and Alabana an additional allowance of Zb^ a bushel is made to covor further losses fron reduced yields, the Office of Price Adr.iinist ration said this week. The f.o.b. shipping point ceiling will be $3.70 a bushel for apples grown in the states of Maine, New Hampshire, Vemont, Massachusetts, Con- necticut, Rhode Island, New York, Pennsylvania, New Jersey, Delaware, Mary- land, Virginia, Vfest Virginia, North Carolina, South Carolina, Georgia and Florida. The $3.45 ceiling price which applies to the remainder of the country includes a "disaster" allowance of 30;z^, effective as of June 21. That in- crease resulted in the retail ceiling price of fresh apples being increased about a fourth of a cent r. pound. The additional increase of 25;^ a bushel granted this week for apples produced in the eastern seaboard states will increase the retail ceiling price for those apples another \^ a pound, making the total retail increase about -g-/ a pound. The price increases v/hich apply to fresh apples are mandatory under the Stabilization Extension Act, v;hioh provides for increased ceiling prices when yields are substantia lly reduced by unfavorable growing conditions. The additional increase in the eastern states is necessary because the reduction in yield in those states is greater than in other sections of the country. (Amendment 132 to Maximum Price Regulation 426 - Fresh Fruits and Vegetables for Table Use, Sales Except at Retail - effective July 21, 1945.) APPLES PREVENT SPROUTING OF POTATOES IN STORAGE The following interesting experiment is reported by Donald Folsora of the Maine Agr. Exp. Sta. in the May issue of Maine Fruit Notes. "The unusual Virarmth of April has started potatoes to sprout unusually early in storages that ordinarily are cold enougli to hold back sprouting. Apples give off a gas that holds back the grovrth of potato sprouts as long as they are exposed to the gus . As an example, at Highmoor Farm many seedling pota- toes v/ere put into the apple storage in mid-April after they had developed sprouts several inches Jong in a potato cellar. Today, May 26, these sprouts are no longer than they were in mid- April. They have developed a hard, round head on each sprout and, judging frora the past experience of other seasons, will not resume gravrth as long as apples are left in -che same storage or un- til the potatoes are taken out and planted. This principle can be used to keep eating potatoes from wasting their strength on sprouts. The idea was discovered and studied scientifically in Kansas and England. The gas involved is thought to be the same gas that is used to ripen oranges and other fruits artificially." -5- DO YOU KNOT That the Plun Curculio is a ninor post of sola's consoquenco in culti- vated blueberries in How Jersey? \'I, E. Tomlinson, fomerly of tho Y/t^lthan Field Station who is now engaged in blueborry insect work at Penberton, N.J., forv;arded sample blueberries to ITaithar.! oarly in Jun(3, 1945, and tyi^ical curculio larvae have eraerged fron them. The infested blueberries were raarked vfith the characteristic crescent shaped scars v/hich are so noticoublo in infested apples and pluras. C. S. Beclcwith, fonnerly entonologist and dir- ector of the Cranberry and Blueberry Insect Investigation Laboratory at Pein- berton, IJ. J., previously reported infestations of this insect in blueberries in 1938. Wild blueberries are not knovm to bo attacked. (V[. D. Vfliitconb). That the ivord "blueberry" is used to designate a group of plants con- nonly called either blueberry or huckleberry the fruit of which has nany sraall, soft seeds in contrast to the true huckleberry vmich has ten largo, hard shelled seeds? In addition to the high bush blueberry (Vacciniuia coryi.ibosun) and the low bush blueberry (V* angustif oliuia) four other species of blue- berries are of inportance in the United States, tho dry land blueberry (V. vacillcjas) and the rabbiteye blueberry (V, virgatura) of the Southoast and the evergreen or box blueberry (V. Ovaturi) and tho nountain blueberry (V. nenbranacoun) of the Northwest. The -^rilue of the lo\; bush blueberry alone is estimated at ^5,000,000 annually. That the state of Missouri, which according to the 1900 Census, had a total of 20,000,OOQ7^ranked first in apple production at that tir.ie? The fol- loviTing states ranked next in order vifith nujubers of trees ranging fron 15 nillion to 8 nilliont IJew York, Illinois, Ohio, Kansas, Pemisylvania, llich- igan, Kentucky, Indiana, Virginia. It will be noted that the state of Y/ash- ington which today produces about one-fifth of the apple crop, was nit in- cluded in the first ten states 45 years ago. That the oldest living grape vine in the United States is said to have been planted in 1587 near Llanteo, N. C? According to tradition this Scupper- nong vine was brought o\'er by a group of col'jnizers sent on an ill fated mission by Sir Walter Raleigh. Many thousands of cuttings havo since been taken from this mother vine, a 125-acre vineyard having been planted nearby. The old mother vine, rambling fron its giant, gnarled trunk over nearly an acre, is said to yield as much as 150 bushels toinually. That a strav/berry plant, with its progeny of runner plants, is capable of producing at least one quart of berries. On an acre basis this v/ould re- sult in only a fair per acre yield. If plants are set 5x2 feet apart, such a planting involves 4,356 plants per acre. The average producti ■)n in the Faliaouth area in 1944 is reported to be 3,36^pe'r acre. In 1940 tho yield was 4,600 per acre. That tho widely publicizod insecticide, DDT, is effective over a long period of tine because it is not soluble in water and does not evaporate or volatilize appreciably? DDT is effective against a v;ide range of insect pests but there are a ni-unber of posts against which it v/orks only moderately well or is quite ineffective. An insect can apparently absorb DDT through its feet. Hence, a snail deposit v/hore the insect v/alks may prove effective.

Tvro hours v/ere required to spraya 40-acre block. Using a high concentration in oil enulsion, only a pint per tree was said to give conplete coverago because of high atonization and high air turbulence fron the plane's propeller. That the prices of all coni-.ioditios bought by farraers in Hay of this year were, on the average, 44 percent higher thsui in 1935-39 while fanu wage rates in May Virero about three tines as high as they v;ere in 1935-39. U.S.D.A. figures on fam wages are shown in the following tfiblo. Per month, with board Per month, without board Per day, with board Per day, without board That iess than lO^o of the nation's retail stores are equipped to handle frozen fruits and vegetables? In viev/ of the tremendous expansion in this field (more than 500,000,000 pounds were packed last year), the prospects for post v;ar development are tremendous. That a 4-H Club project in Grainger County, Tennessee added 235,000 pounds of viild blackberries to the national supply of fruit last year? More than 500 4-H Club mombors took part in this project. The pickers re- ceived 7 cents per pound for the berries, 1 cent going to the club v/hich received, crated, and paid for the berries. 7,500 checks, amounting to $16,000 v;ere issued, some families receiving as much as $200. That the irritation due to poison ivy may be relieved by painting the skin with a ferric chloride solution made as follov;s: Tincture of ferric chloride, 205.0; Glycerine, 50^; V/ater, 30^? It is said that this material will reduce the inflammation and irritation luid control their spread to other parts of the body. That the Office of Price Administration has recently set up a tentative schedule to govern the lifting of price controls in throe important catagories affecting the farmer? V/hile no specific dates have been set, controls are to be lifted in the following order: (1) Basic materials whose output has been greatly expanded during the war, including al'aminu^n, copper, and zinc are in this first class. Also to be among the first products to be freed fron the ceiling are fresh fruits and vegetables, and cereal products. (2) Steel, machinery, castings, most paper products, rubber goods, soap, household goods, home furnishings, clothos, shoes, moats, processed foods, and later sugar. (3) Building matp;rials, household appliances, automobiles and furniture. That yields of apples in 131 Yakima and V/enatchee orchards in central ■Washington reached a new high of 500 boxes por acre in 1944 as compared with 374 in 1943? Those grov-rers produced 1,608,401 boxes of apples at an average cost of $1.41 per box. That a single application of nitrogen applied in an apple orchard in early spring has been found as effective as splitting the amount and applying half of it later? A single early application is found to be more effective thtui the same application roade in late spring. -7- That the per capita annual consumption of apples decreased from 68 pounds in 1910-1914, to 43 pounds in 1935-1939? Citrus fruits offer the strongest competition. Their consumption during this period increased from 19 pounds per person per year to 49 pounds. Bananas and other fresh fruits (mainly peaches, grapes and pears) have not shovm any marked trends in this regard. The per capita consumption of bananas has fluctuated betv;een 15 and 25 pounds. Of citrus fruits, oranges are still liked best and are used in grea test volume, though grapefruit showed an eightfold increase in con- sumption from 1.4 pounds per capita in 1910-1914, to 11 pounds in 1935-1959, Even lemons seem to have gained in popularity. That the word "fruit" from a horticultural standpoint is defined as "The edible pulpy mass covering the seeds of various plants and trees, as the orange, apple, pear, berry, otc," and from a botanical standpoint, "The matured seed and its contents, together vdth such accessory or external parts of the inflorescence as seem to bo integral \vith them"? The seed of a dandelion is therefore as worthy to be called a "fruit" as a luscious peach. That some rain fell in Amhorst on 53 of the 92 days of May, June and July? The excess rainfall for the first six months of 1945 amounts to more than 10 inches. That a white f orm of the common blackcap is sometimes found growing wild? A few days ago a fon.ier student dropped in at the State College with a sample of these berries gathered on Mt. Toby. The fjruit is amber yellow in color and is technically known as Rubus occidentalis, variety pallidus. That the genus Prunus, one of the sub-divisions of the Rose Family which includes pluJis, cherries, peaches, nectarines, apricots and ali.ionds, is divided into no less than 82 distinct species of plants? Ilany of these species are again divided into large nuiabers of viirietiea. That a fairly definite relationship exists in most orchards between the percentage of apples in different grades and the fact of closely or vddely spaced trees? The following table taken from Bulletin Ko. 443 of the r/asliington Agricultural Exporinent Station brings out this relationship. „ „ , , % "Extra Fancy" "^ "Fancy" % "C Grade" Zone of tree t^ Close Wide Close vade Close Wide Ground to 5 feet above 0 31 4 48 96 16 5 to 10 feet 7 35 39 55 54 8 10 foet above the ground "to top 65 79 24 18 10 2 That the forerunners of our present large strawberries were first in- troduced to Europe in 1712 from Chile? In August of that year five plants arrived in France which, together v;ith later importations, laid the founda- tion for strawberry grov/ing in Europe. Later those plants were crossed with pollen from Europfjan and North American species and from the seed secured, a new race of largo fruited strawberries originated, better than anything pre- viously knov\m. That apple varieties vary considerably in tlioir content of Vitamin C? A variety under study in New York State is found to contain about 10 times -8- as much as is nornally found in an apple. Incidentally, the additi)n of synthetic Vitanin C is said to prevent browning of dried cr frozen peaches? That careless practices of fo^d shoppers, principally ivonen, cause an annual loss of nore than 8,000,000 pounds of fresh fruits and vegetables. By handling food thoughtlessly and roughly, purchasers spoil perhaps 1500 tons of poaches, 4500 tons of tomatoes, and large quantities of other per- ishable foods every year. The above nentioned 4000 tons would supply the full needs of 143 array divisions for a week. That a lailky disease spore dust offers nuch promise in the control of Japanese beetle. The purpogQ of the product is to inoculate the soil against the grub by introducing into the treated area a disease that kills quickly and multiplies rapidly. Its application is simple and the inocu- lation remains effective for many years. Under normal conditions subsequent treatments are not necessary. That one of the big pr iblems of the Mcintosh grovrer, probably next in importance after scab control, is that of regulating the nitrogen appli- cation in such way that he obtains the highest production consistent with good fruit color? Since leaf color is directly related to this problem, a set of nevj color charts which bear 7 shades of green should prove useful in years to come. These charts range in color from a greenish yellow to a dusky olive green and are based on leaves taken from Mcintosh trees which were under knovm nitrogen treatraents for three years. That Connecticut growers arc suffering some damage this season from the 17-yoar locust? Damage to young trees is caused by the egg laying punc- tures in the branches. One grovrer is roportod to havo wrapped the young trees in a 40-acre orchard vdth totacco cloth to avoid dar.mge from this pest. BLUEBERRY "STUNT" DISEASE The blueberry "stunt" disease has recently been found in Massachusetts. This disease is very serious in North Carolina and Now Jersey where it some- times spreads very rapidly. It has boon found also in New York and Michigan but is spreading very sl^owly or not at all in these states and in Massachu- setts, The "stunt" is a virus disease transnissable by budding, grafting or cuttings. Although it is probably spread by some insect, the exact meumer of spread is not known. Diseased plants are stunted in their gr>Jivth, loaves are mottled, cupped downward, and stunted, fruit is small, bitter and useless. Diseased plants should be removed as soon as found and burned. — J. S. Bailey \ \ '"\L. ^- \ 'T? i\ i\\J I t^a August 31, 1945 Prepared by the Fruit Program Committee of the Extension Service W. H.

The fairly regular slope, evBn if curved, lends itself to contour planting. The roly-poly, hummocky topography, however, is not adapted to contour planting. It happens, however, that the soil types of New England best suited for orchards have fairly reg- ular slopes. The hummocky, irregular topography is more likely to occur in • the soil types ill adapted to orcharding, such as Hinckley.

In either cultural system orchard equipment can be more easily and less ex- pensively hauled on the contour than up and down hill. However, the freedom of movement is largely restricted to the horizontal; this is almost necessary anyhow on slopes greater than 15 per cent. Provision must be made for turn- ing at the end of contour rows. Sheet erosion occurs on all sloping culti- vated land. It is often so imperceptible as to be hardly noticeable. Its effect is cumulative and serious in the end. It is not uncommon to find as a result of sheet erosion during the years that good topsoil has accuraulated to a depth of several feet at the foot of a long slope. Another type of soil erosion that orchardists often have to cimtend with is road erosion. In many cases this type of erosion can be reduced to negligible proportions by proper road placement through careful planning in advance of planting, Orchardists of this state having problems of soil conserva- tion and land improvement, and most of them do have such problems, will be interested in the possibilities in these fields through soil conservation districts. The soil conservation enabling act, recently passed by the Mass- achusetts Legislature, makes it possible for farmers of a given area to or- ganize soil conservation districts. Through districts technical service in conservation can be obtained free of charge, and the use of heavy equipment of different kinds can be obtained at low cost. Many advantages may accrue to farmers through districts. The fist step in obtaining a district is to file with the State Soil Conservation Committee a petition bearing the names of a number of land occupiers in the area under consideration, — A. B» Beaumont A RECORD SHORT APPLE CROP What a pity this year, when there is need for every possible pound of food, that Massachusetts, Nevi England, and practically the entire East should suffer such a disaster in connection with apple crop prospects I It has been a case of down, dovm, down, all season. Ever since the frost first struck, following that "August weather in March," there has been a series of wallops including serious lack of pollination, heavy drop, wet, scabby v/eather, all of which have taken their toll of merchantable fruit which will be available this season. It now sums up to the shortest crop in New England since 1910, It is even smaller than the 1921 crop which \re old timers thought was a ter- rific disaster. As it stands at this v;riting, the apple crop in the entire North Atlantic area, including New England, is only a little more than 10 million bushels compared with about 35 million last year. In the South Atlantic States, which takes in the very important Virginia section, the re- duction is from 23 million last year dovm to a meager 6 million this year. In the Central States it is about 50^o of a crop, from about 18 million to 9 million. -3- Tlhile it may sound disloyal for an old Yankee to say it, the place for an apple man to live this year is in the Pacific Northwest. Out there they have a real crop. They have had some av/ful tough times dur- ing the depression, but in the past few years they have come back strong and this year's nice crop, benefitting from higher prices as a result of the eastern shortage, should make apple selling a nice proposition for western grov/ers. To sum it up, the estimates as compiled in August shov; a United States crop of 68,882,000 bushels, compared with 124,754,000 last year and 119,046,000 for the ten-year average. In viexv of the short crop^ some comment here on the apple ceilings seems quite appropriate. The "disaster" adjustment to the ceiling prices, which is effective through September 30, makes the price in the east- ern states $3.85 per bushel f.o.b, to growers, and $3.95 to growers' sales agents and to growers who qualify as shipping point distributors (which many in New England do). This ceiling applies to all the East and to some Western States, but does not apply to the Pacific Northwest. In California, Washing- ton, Oregon, Montana, and Idaho, the ceiling is $3.19 to growers, ^3.29 to growers* sales agents, and shipping point distributors. The mark-ups as scheduled at present are the same as last year. For sales in the market there is a mark-up of 40 cents where sales are on commission (and 30 cents if the shipment is from a shipping point distributor or grwrers' sal^s agent). P''or apples which are owned by the seller in the market the mark-up is 45 cents. For apples delivered to retail stores the mark-up is 70 cents. In all of these cases the cost of transportation may be added. The $3.85 figure applies on standard containers, \uhich in- cludes the eastern apple crate and the Massachusetts standard box. Yj'here apples are sold in non-standard containers, the f.o.b, price is 8.56 cents per pound for graded and packed fruit, — Walter E. Piper Massachusetts Division of Markets DICIILORO - DIPHBNYL - TRICIILORETHAIJE The end of the Japanese Y/ar and increased production facili- ties undoubtedly mean that DDT v;ill be available to civilians in larger quan- tities in 1946, and Massachusetts fruit growers are already wondering hoiv to use it in their orchard insect control schedule. Although about 25 years of normal experimentation have been croweded into the last three years, there are many things about DDT which are not yet known. Furthermore, the extremely unusual grov/ing season in 1945 will cast a reasonable doubt on the results of this year and v;e wonder if they can be repeated in a more normal season. -4- Most of the preliminary results have been favorable, and a dosage of 1 pound of DDT in 100 gallons of spray is generally accepted as most desirable on fruit trees. At this rate, outstanding control of codling moth, leafhopper and Japanese beetle has been obtained. DDT appears to be exceptionally compatible with other insecticides and fungicides and promises to provide many desirable combinations. Preliminary experiments indicate satisfactory compatibility v;ith Fermate or Puratized for scab and other di- seases; with DN for red mite; v/ith nicotine for aphids; and with lead arsen- ate for plum curculio. It is safe' on peaches and we expect to develop a satisfactory schedule against the Oriental fruit moth. Some reports show a lack of uniformity in the manufacture of DDT, and chemists have found the presence of isomers which are chemical mix- tures containing identical elements in similar proportions but in different arrangement and varying in their action. DDT has already been micronized, fused vrith sulfur, dissolved in paint, and sprayed onto carrier particles to form a dust. Many other formulae, processes and combinations will be made before the most satisfactory form for each purpose is established. The effect of DDT on other animal life is being thoroughly studied. Some birds are killed by eating poisoned insects or by drinking im- pregnated water. Many native pollinating insects will be killed, especially where flov.'ering cover crops are grovni in the orchard. We are confident that a practical and profitable schedule for using DDT in orchards can be worked out. But, please, be patient. Give us time, — Yf, D. ?/hitcomb OYSTER SHELL SCALE A PROBLEM IN MAKJE APPLE ORCHARDS During the past four or five years oyster shell scale has been on the increase in a number of Maine apple orchards. At present the scale presents a real challenge in some of the infested orchards. Although the problem appears to bo most severe in Maine orchards, there are several aspects of the situation that are of interest to apple growers throuj^h a much wider section of Hev;^ England, Destructive Hpbits of the Scales. As the name implies, infested apple twigs appear as thougli encrusted with minute oyster shells. At first only a few scales may be present, and as they are about the same color as the apple bark J they are easily ovetlook^d. As the infestation increases the smaller twigs become heavily encrusted, and a fovi of the scales settle on the growing apples. Finally the whole tree^ in^iluding the tru:il: and large limbs, as well as the tv;igs, may become heavily infested by the scales. As the in- festation gr'T.vs, the tree becomes weakened; small tvdgs bo^in to die, and later larg:jr limbs are killed by the scales. In some orchards only a few scattered trees are severely infested by the scales. In other orchards, in- festation is widespread. -5- Life History. The oyster shell scale spends the winter in the egg stage, concealed under the protection of the old scale cover. In the spring, soon after petal fall, the eggs begin to hatch, and hatching continues over a period of ten days or more. The newly-hatched scale is a ninute, active, crawler with six legs. The crawler soon settles down, inserts its sucking tube into the apple bark, and begins to form its protective scale cover. After the scale insect forms its protective cover, it sheds its legs, and never moves from that spot. The scale grov.'s in size until late summer, vifhen it reaches full size, and eggs are soon formed. After the eggs have been deposited, the parent insect under the scale shrivels away and- dies. Each scale may deposit from 50 to 100 or more eggs. Control Problems. The present infestation of oyster shell scale is most severe in well-cared-for orchards, and especially in orchards which have been consistently dusted. It has been observed that neglected trees may be practically free from scales, while adjoining v^'ell-treated commercial orchards are severely infested. This suggests that the spray or dust in some way favors the development of the scales. Perhaps the sulphur destroys many of the natural enemies which othoi'v.'ise v;ould 1 Ih^i September 28, 1945 Prepared by the Fruit Program Committee of the Extension Service W. H.

Fruit growing is an at- tractive business. The fruit itself, the tree, the outdoors, and the type of work will have an appeal for many. Without doubt a good many fruit growers will have an opportunity to advise some veteran before many months have passed. Perhaps he will be a relative, or perhaps some young friend. The request for advice may be given in an informal or casual vfay, but it will be no less important to the man concerned.

Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. -2- I am quite sure that on© of the first things you would ask him would be I What is your training and experience with fruit? Probably most fruit growers would suggest some agricultural school or college course, coupled with actual work in an orchard as a preliminary. The grower might then turn to some of the difficulties of orchard- ing so that the young ■veteran would have a thorough understanding of the type of business he was thinking of entering. It is not easy to get a start in orcharding, he would say. In the first place, h© must have a good-sized orchard - 20 acres of bearing trees at least - in order to handle it effi- ciently. The equipment is expensive and unless you have a good sprayer and ■imilar tools you will never be able to grow good fruit. Thus the original investment in a good bearing orchard is sure to be large. On the other hand, it takes a long time for young trees to come into real bearing. This makes it hard to start on a small scale, for one must vmit too many years before there is a profitable income. However, the general outlook is favorable. We can look forward with considerable confidence to a period of good times when most people are working and can afford to pay g.iod prices for apples. It may well be a period of reward for the established orchardlst, but undoubtedly this same orchardist would caution the veteran that to profit by these prospective good times he must have plenty of espies to sell. If he were to reverse the process and spend the years of good times in building up an orchard, he would have to pay for it during a less profitable period, if such a time should come. Therefore, to the veteran who may be considering coming back to his farm orchard, all of this would have its advantages. Even this veteran should give his home place as careful appraisal as though he were buying a new one. The size of the farm, soil, location, prevalence of frost, number of trees, equipment, living conditions and financial arrangements should all enter into his decision, for they all will have an effect for many years upon his income. To come back to the m n who is starting in on a new place, without doubt the established grower would emphasize to him the need of having an immediate source of income. This might come from a large block of bearing apple trees. It might come from some other farm enterprise, or it might come from some type of work off the farm, but it must be large enough to pay the family living expenses and aleo the costs of developing the farm or orchard for larger future profits. If a veteran can get started on that basis, he will have a solid foundation under his business for the years ahead. We shall, without doubt, have a large group of veterans in our next generation of fruit growers. I think w© can expect too that our present fruit growers, rather than professional counselors, ^re the ones who will give these veterans the sound advice and the training that will get them off to a good start, — James W. Dayton -3- DDT SHCT/S PROMISE IN RECENT TESTS Experiments by various federal agencies in several areas, notably New England and Pennsylvania, show oxcellont results against gypsy moth by the use of DDT from ground applications and by airplane. Som.e of the results reported indicate not only commercial control but actually approach very closely to extermination, at least in the experimental areas. In several of the test areas, DDT applied for gypsy moth control was found to have giv- en excellent results against a number of other injurious insects including such pests as cankerworm, budworms, etc. Although final reports are not yet available, some of the results surpass those anticipated and lend hope to those who have heretofore felt much concern over the devastation wrought by the gypsy moth in many areas of the state this past sumraer. The Japanese beetle, a species which is already pre^sent over much of the state and' which this season was fully as conspicuous as in any recent years, is another pest against which DDT has given excellent results. Sprays and dusts have proved very effective against the beetles, and preliminary tests in the application of DDT to the soil indicate that the material is very effective against the grubs; much more so, pound for pound, than is the case with lead arsenate. The material also has shown a very' marked residual effect against the beetles and thus enabled growers by one or, at most, two applications to secure protection throughout practically the entire season of beetle activity. Soil treatments v/ith DDT appear to be a very promising addition to control measures and may serve as a valuable supplement to the use of the so-called milky disease or spore dust which is also giving ex- cellent results against the Japanese beetle grubs in heavily infested areas. The oriental fruit moth for many years shov/ed such an excellent defense against insecticidal applications that its control by spraying or dusting was almost despaired of. At the present time the so-called oil- sulfur-talc dust has given excellent results throughout the midwestern peach areas, against this insect. Many Massachusetts growers have used this dust and reported excellent results. For those grovrers who are equipped to spray, a fixed nicotine such as Black Leaf 155 has also shown premising results. Both sprays and dusts are available commercially, and apparently each year more and more growers are availing themselves of these materials. Recent tests also indicate that DDT combinations (dusts or sprays) have also shown very promising results. It is encouraging to note that the new material DDT has shown it- self to be so efficient against all three of these very serious pests, and the assurance that DDT in different formations will be available commercially by another season is nev/s that will be v/elcome to fruit growers, ~ A. I. Bourne MAGNESIUI.I SPRAY PRECIPITATE (An apparent change in the spray mixture, as evidenced by an in- creased amount of precipitate, has been observed by a fe\t grov/ers, when mag- nesium sulfate is placed in the spray tank. The following statement by -4- Dr. C. A« Peters of the Department of Chemistry at M.S.C. throws some light on this problem,) The use of magnesium sulfate in the spray material, as a source of magnesium for the orchard gives rise to new problems. If mixed with an alkaline spray, white magnesium hydroxide is precipitated in voliuninoua quantity. The substance, in itself, is harmless as it has a solubility of less than one-tenth of one per cent. The precipitate is colored dark by the lead sulfide if lime-sulfur and lead arsenate are present. The black substance does not cause burning. The alkaline spray materials that bring about the precipitation of magnesium hydroxide are lime or dry lime-sulfur. The dry lime-sulfur is much more alkaline than the liquid, in fact, generally, the liquid is nearly neutral. It is a question whether there is more black precipitate when al- kaline substances are present or whether it just looks more abundant spread out through the copious white precipitate. Anyway, the amount of the black' precipitate is a measure of the amount of decomposition of lead arsenate and too much decomposition may give rise to harmful products, ~ C'. A. Peters EFFECT OF MOVING GRASS ON MOISTURE CONSERVATION To mow or not to mow the grass in an orchard, - that is the ques*- tion^ Will the benefits of hand mowing around the trees, for example, justify the cost? How much water, if any, is conserved when we cut a growth of grass and does the stage of maturity make much difference? These questions were put up to Dr, Wm. G. Colby a few days ago. His reply, which for lack of space was omitted from August Fruit Notes, is as follows » "In order to inject some new ideas into the problem you recently raised pertaining to the mowing of orchards, I submitted your memorandum to Dr, V. G. Sprague at the Regional Pasture Laboratory in State College, Pennsylvania, I am submitting Dr, Sprague 's reply together with a re- print of some experimental work which he has done on water utilization by Kentucky bluegrass and alfalfa. The results which Dr. Sprague ob- tained indicate rathfer definitely that more frequent cutting of grass will conserve more moisture than infrequent cutting. "It would seem that the problem of mowing orchards is one of balancing the extra cost of frequent mowing against advantages gained in moisture conservation. The answer to this problem will undoubtedly vary fran one farm to another. Where orchards can be easily and quickly mowed with tract ional machinery, two mowings would be more satisfactory than one» Where mowing is difficult and expensive then I am inclined to feel per- sonally that a single mowing would be the most desirable. If two mow- ings are practiced, I suspect Dr. Sprague 's suggestion as to stage of plant growth is quite accurate. But where only one mowing is practiced I am inclined to think that my earlier suggestion of mowing when the vegetation was fairly well along toward maturity would be satisfactory. This would call for mowing a bluegrass stand in June and timothy, redtop, or witch grass stand in late June or the early part of July," -5- And here are the comments submitted by Dj.. V. G. Sprague; "Some years ago it was noted that the very heavily grazed Kentucky blue- grass pastures in southwestern Wisconsin remained green during severe sum- mer droughts whereas adjacent, moderately grazed pastures dried up and turned brov/n. To investigate the reason for this, an experiment was per- formed in the greenhouse. Low carbohydrate (-CHO) plants v;ere obtained by frequent clipping. "In 1938 and 1939 here at the Laboratory a number of clones of Kentucky bluegrass were grovm in gravel culture and the water used was measured. A number of clipping treatments were used. The greatest amount of v;ater was used v;hen the plants were clipped every 12 weeks and the least when they were clipped every 10 days — .the ratio being about 8 to 1. The water transpired by a plant increases considerably as it approaches and during heading, or as the total leaf area increases. "For orchards, as a matter of conserving the moisture in the soil as well as to provide a mulch which would allow greater infiltration, less runoff and less surface evaporation, it would seem to me advisable to cut the grass the first time about when the head was emerging and then later in the summer when the recovery growth had attained any appreciable size- say 10 inches high. It v:ould seem advisable to leave the cut grass on the ground rather than remove it. This probably would have as great an effect in increasing infiltration as in reducing evaporation since the latter water loss is probably confined to the surface 4 or 5 inches—the greatest v/ater loss from the soil being through the roots of growing plants. On droughty soils or in years when drought appears imminent, it might be advisable to out before the emergence of the head and clip again vihon recovery was appreciable." — Y7m. G. Colby SELECTING THE BLUEBERRY SITE First of all, the location for the blueberry field should be as free from the damage of late spring frosts as possible, for while the culti- vated varieties seem to resist frost better than most of the native varieties, they sometimes are injured in blossom time and even after fruit has started growing. Select a site with good ai'r drainage, not a frost pocket. In selecting the site there are three important characteristics of the soil to keep in mind; 1. The soil must be acid. A soil with a pH test of 4.4 to 5.1 is best al- though they will grovf where the soil is as low in acidity as pH 7. They vfill stand high acidity better than too low acidity, and will do well in soils hav- ing a pH test lower than 4.4. The Experiment Station will be glad to test samples of soil at any time to determine the acidity. 2. The soil must be loose in texture, either a sandy peat or a sandy loam. A 50-50 sand and peat is perhaps ideal but providing the moisture is right, a sandy loam gives very good results. Heavjr clay soils v;hich tend to pack should be avoided, although they can be made more suitable by mixing in sand or mulch. It is very iiaportant that soil is loose enough to enable the roots to get their oxygen. -6- 3. The correct amount of moisture appears to be the most important factor in successful blueberry growing, for while some variation in acidity and texture of soil will be tolerated, the water content must be just about right. Therefore, it is best to select a site which is as nearly right as possible and then by either drainage or irrigation to make conditions still better. Wild varieties grow in swampy places, but they have bailt up a mossy mound at their base so that the roots can get oxygen. In locations of this nature, where it is not possible to lower the water table, it is sometimes practical to prepare the lajid in such way that the plants are on ridges. In other cases, where material such as sajidy loam or plain sand with a peaty bottom is available, conditions may be corrected by adding fill. On the other hand, while some species in the wild grow on high, relatively dry ground, the cultivated blueberry will not. At least it will not produce first class fruit, except on hillside locations where water from above is constantly passing down the slope. Where dry conditions exist, it may be practical to supply water. Underneath irrigation would be preferable although overhead sprinklers have the added advantage of supplying frost protection. Heavy mulching is beneficial on too dry locations. In general, on fairly level land, the plants should be from two to four feet above the water table and even higher on certain types of land which keep moist through the summer. After selecting the site, one should take sufficient time to clear the land properly and prepare it for planting. It should be well worked up by plowing and cross discing or by some other satisfactory method, and when ready for planting, the plants should be set not closer than 8' x 8'. They may be set 8' x 4' but only with the idea of removing every other plant in the row after 6-10 years so that the permanent planting will be 8' x 8'. (The foregoing discussion of blueberry soils and culture was written by a pioneer blueberry grower, John Carleton of Sandwich.) POIV APPLE PICKING PROJECT - A PROGRESS REPORT German Prisoners of War are harvesting a fairly large proportion of the scattered apple crop in the Nashoba area. Up to September 15 they had worked a total of 32,639 Man-Hours in Middlesex and V/orcester Counties and 5,972 in Hillsboro County, N.H. Transportation is furnished by the grower for which he receives an allowance based on mileage and number of POW's transported. The total transportation allowances in the two areas mentioned above are $893 and $279 respectively, while the net balances paid by the growers are $18,690 and |3,005. In addition to 44 fruit projects (one cranberry) thus far, at least a dozen -uegetable grov/ers are availing themselves of POW help. During the 5-day period, September 10 to 14, the following numbers of POlV's were at work. Mass, (apples) - 394, 455, 408, 380, and 242 (total man-days, 1899); Mass. (vegetables) - 191, 188, 219, 230, and 215 (total man-days, 1,043); N.H. (apples) - 29, 132, 129, 132, and 103 (total man-days, 525). The min- -7- imum unit is 15 workers under one anued guard, although the unit is sone- times reduced to 14 on account of illness. Thus far there have been no more than half a dozen cases of illness or accident in the field requiring a trip by a staff car to transport a P0V7 back to camp. Many grav;ers have expressed their satisfaction witli the work done by the PQT's this season. Here are quotations from two letters: "They vrere in every way cooperative, willing, able and intelligent, far more so than any group we had last season." "I am writing to commend the work of the prisoners of war v;ho picked apples in my orchard Sept. 5 to 10. These men, whose names I list below, started off slowly but once acquainted with the work, they became steady, industrious, and cooperative workers. The fore- man and I have felt ourselves most fortunate in having this particular crew and are sorry to have run out of apples just when these men were reaching top notch ability. Y/hatevor their political views may be, I take my hat off to them as workers." In one orchard where one or two units worked nine days and picked a total of 3,972 bushels of apples, the numbers of bushels picked per man per day v;ere as follows; 21-, 24-*, 26, 23-, 25, 25*, 18-, 10-, and 22* (average, 21*5). The apple picking project will continue until about Oct- ober 20. LOOKING AHEAD ViTith the end of the war and the "reconversion" to peace, conditions are changing rapidly. How will this affect the fruit grov/er and what should he do about it? This question was the basis for a series of discussions by professional horticulturists at Nev;- Brunswick, Nev/ Jersey, on August 27 and 28. Representatives were present from most of the northeastern states and from the United States Department of Agriculture. As a result of the discussions, the follovdng recommendations and suggestions regarding the future of the fruit industry vrere dravm up; 1. Remove orchards v/hich are unprofitable either because of age, un- favorable soil or climatic conditions, or undesirable varieties, 2. No increase in the present total commercial production of tree fruits seems desirable under the apparent marketing conditions. New plant- ings should be made only to maintain present production and to secure a proper succession of plantings. 3. More thought and study should be given by many fruit growers to the / possibilities of some diversification in their source of revenue aside from one kind of fruit. 4. Groirers are advised to give more attention than previously to the selection of the site and soil for any new tree fruit planting ta\d to the best land use on their own farm. -8- 5. No varieties should be commercially planted without a searching investigation by the grower of their merits from the standpoint of both tree and fruit qualities and particularly with respect to their adaptability to the locality where they are to be planted. 6. Better varieties are needed in most districts, 7. plant well-grown, vigorous, healthy, virus-free trees with uniformly strong, congenial rootstooks. 8. An increase in the yield per acre of a good grade of fruit is impera- tive. 9. Every effort should be made in cooperation with public sind private agencies to reduce the con^^lexity and cost of production and marketing, 10, The growers need to assume more responsibility for the condition of fruits as delivered to the consumer. In future issues of Fruit Notes these recommendations will be discussed further, — J. S. Bailey APPLE STORAGE COOLED BY NEVf METHOD After months of exhaustive tests, a large apple storage in the Wenatchee district in Washington is now being cooled by what is known as the reversed air method. In this storage which holds 260 carloads and looks like a civic auditorium, a huge blast fan pumps 50,000 cubic feet of air per minute past great banks of cold pipes. The air goes through one set of ducts for three hours and then is reversed automatically when a time clock sets the machinery in motion which shifts the dampers and sends the air in the other direction. The intake ducts thus become outlets, and the air passes through the rooms in the opposite direction. This makes it pos- sible for air at a temperature of 26° to be blown through the rooms because its direction will be reversed before the fruit near the intake ducts is frozen. The temperature of the air rises a few degrees as it travels across the room although every three hours the direction changes and the warm side becomes the cold side. Extensive tests have shown that less than one degree difference in fruit temperatures will be experienced in any part of the stor- age room, - corner, center, top or bottom. This new method, therefore, means not only quicker cooling but more uniform cooling. Believing that the whirling compressors are the most impressive part of a cold storage plant, the architect has placed them in this building where passers-by csin see the wheels spin. A huge sound-proof plate glass panel separates the manager's office from the compressor room. Every con- ceivable modern feature has been built into the plant to keep pace with the new reversed air installation, and to improve the quality of the product during the highly competitive years ahead. 7 '-.5^ October 29, 1945 Prepared by the Fruit Program Committee of the Extension Service W.

Moreover, even though such a spray mixture were discovered, its use could not be expected to be very effective for the reason that in most seasons many scabbed leaves fall to the ground before the eradicative post-harvest spray could be applied to the trees. Hence, for the present, the use of an eradicative spray to the trees following harvest seems to be out of the question. There remains, then, the advisability of a ground spray in the late fall or early winter. It is a well proven and accepted fact that early spring applications of certain sprays to the orchard floor are very effective in destroying the Scab fungus in the overwintered leaves. Effective sprays in- clude one-half per cent solution of sCdium dinitro-ortho-cresolate (Elgetol)j 100 pounds of sulfate of ammonia in 100 gallons of spray; 100 pounds of ni- trate of soda plus 4 pounds of calcium arsenite in 100 gallons of spray. Are these same sprays equally effective v>rhen applied to the leaves on the ground in the fall? There appears to be no experimental evidence on this question. Pathologists who established the usefulness of the springtime eradicative sprays have indicated (through correspondence this fall) that the same sprays might be expected to prove effective, although it is point- ed out that the Scab organism is not in the same stage of development in the early winter as it is at delayed-dormant time in the spring. Further- more, it v;ould be advisable to wait until practically all the leaves are down before such a ground spray is applied in the fall. It is felt that if such caustic sprays are applied in late fall or early winter to both the ground and the remaining leaves on the trees,. Injury to fruit buds would likely result. Hence, it seems advisable for growers who ordinarily cannot get into their orchards at the silver tip to delayed dormant period and who wish to try out a fall or early winter eradicative spray for Scab control, to wait until all of the leaves are on the ground. Then wet the leaves thoroughly on the ground with one of the sprays mentioned above, preferably Elgetol one-half to one gallon in 100 gallons of spray. Thorough coverage of the floor cannot be expected v;ith less than 550 to 600 gallons of spray per acre. For those who generally are able to operate the spray rig in the orchard in the early spring, it is preferable to wait until that time of year to apply the eradicative spray to the orchard floor, — 0. C. Boyd SHRIVELLING of APPLEI3 IN STORAGE Studies on shrivelling of apples in storage by Dr. Smock of Cornell University indicate that the early part of the season often is a critical period. Dry boxes and wooden walls absorb a great deal of moisture and keep the air dry. The obvious solution is to keep the floors and perhaps the walls v/et, especially in the Fall months. Vfetting the boxes themselves would be an even more effective procedure but might not be advisable if apples are stored in market boxes, — R. A. Van Meter -3-. COIISERVING THE ORCHARD SOIL Since good orchards are almost invariably found on sloping areas of fairly high elevation, the problem of erosion is of real concern to the fruit grower. In one such orchard, sheet erosion over a period of thirty years has raised at least tvro feet the layer of loimy, surface soil above a stone v/all at the base of the slope. At the top of the hill one is con- scious of walking on a compact, cement-like material, the subsoil of years past. But sheet erosion, or a downward shift of the surface layer is only one of the problems involved. Gullied roadways, unequal stimulation of trees through a movement of nitrates, exposure of roots to winter injury and a disrupting of new seedings are also of concern to anyone interested in orchard management . The writer has often wished that a particular hilltop orchard which towers above an extensive marsh, might be the recipient of an "upward shift." Its response to a layer, one foot in depth, of fertile loam crammed full of organic matter, challenges the imagination. The only hitch in this vision- ary project is that a loamy soil, once shifted to a lov/er level seldom if ever moves back to its original position. Our job is to prevent this soil movement, so far an possible, and here's where the principles of soil con- servation should be applied. Are all soil types and all kinds of topography suited to contour planting? The answer is definitely "No." A hummocky area or one with abrupt, irregular slopes is not suitable because they involve either rows with drastic curves, or short rows. But if we make a study of the various soil types, v;e will find that those best suited to the grOF/ing of tree fruits such as the Paxton, Charlton, Colrain, and Gloucester series are generally of a slope well suited to contour planting. Anyone contemplating the setting of a new orchard should become familiar with the available soil types and plant only on those rating at least lQi%. He should also seek the council of a skilled soil conservationist. This service may be arranged through the county extension office. Keeping the soil where it is, making water penetrate where it falls, and preventing gullies are easier of accomplishment than most folks realize. They do not entail the same practices in every orchard. But in every case one must cooperate with nature. If harrowing is to be done, the driver should travel as nearly on a level as possible. Alternate strips may be more safely harrowed than the entire orchard. And it should be borne in mind -that a heavy cover of vegetation, either growing or in the form of a mulch is an excellent means of encouraging the penetration of rainfall. Water, soaking into the soil where it falls, comes into contact with roots which need it, while that which flows to the foot of the slope is merely added to an already existing surplus. Soil conservation halts the loss of water, soluble mineral elements, and the finer soil particles, processes which tend to make a poor soil poorer. Post war agriculture must of neces- sity team up vath soil conservation. -4- LOOKING AHEAD (continued from September issue) As indicated in September Fruit Notes, a meeting of 15 eastern pomologists representing 9 states and the U.S.D.A., was held at the State University, New Brunswick, New Jersey, on August 27 and 28 for the purpose of discussing "Reconversion Problems in Fruit Production." On the second day, a series of recommendations and suggestions was drawn up and approTed vj-ith regard to the future welfare of the fruit industry, as follows: 1. Remove orchards which are unprofitable either because of age, un- favorable soil or climatic conditions, or undesirable varieties, 2. No increase in the present total commercial production of tree fruits seems desirable under the apparent marketing conditions. Nev^ plant- ings should be made only to maintain present production and to secure a proper succession of plantings. 3. More thought and study should be given by many fruit growers to the possibilities of some diversification in their source of revenue aside from one kind of fruit, 4. Growers are advised to give more attention than previously to the selection of the site and soil for any new tree fruit planting and to the best land use on their ovm farm, 5. No varieties should be commercially planted without a searching in- vestigation by the grower of their merits from the standpoint of both tree and fruit qualities and particularly v/ith respect to their adaptability to the locality vifhere they are to be planted, 6. Better varieties are needed in most districts, 7. Plant well-grown, vigorous, healthy, virus-free trees with uniformly strong, congenial rootstocks. 8. An increase in the yield per acre of a good grade of fruit is imperative, 9. Every effort should be made in cooperation with public and private agencies to reduce the complexity and cost of production and marketing, 10. The growers need to assume more responsibility for the condition of fruits as delivered to the consumer, 1. "Remove orchards ..,." The Extension Service has been ad- vocating this for years. In \7PA days many unprofitable trees were cut down. However, there are still many orchards which need to be pruned with, an axe. Orchards where the trees are too thick, orchards on poor soils, orchards of poor varieties, need to be given special consideration in order to reduce the cost of production. It may legitimately be asked, when does an orchard become too old to be profitable? Unfortunately, no rule of thumb method can be given for -5- answoring this question. Since conditions vary from orchard to orchard, each grower should consider carefully the records of his older blocks. Are they producinj^ enough to pay for their increased cost of upkeep and yield a profit besides? Orchards on unfavorable soils or sites should be eliminated to increase the efficiency of the enterprise. Orchards on unfertile soils, on soils too dry or too vret, in frost pockets or on sites subject to win- ter injury must be viewed with a critical eye. Sometimes only part of a block is on poor soil or in a poor location. This often results from the old practice of planting in more or less rectangular blocks. Too often a fence or hedgerow has' determined the size and shape of an orchard. The practice of removing hedgerows and stone fences, v/hich is becoming more common among fruit growers, is to be commended. This allov/s the or- chard to be fitted to the soil and site instead of planting that north five acres and then hoping the trees in the poorer places can be carried along somehow. Those poor spots v;ill probably grow better mulch than trees. Remember the New England Seven?' A bulletin illustrating them in color was published in 1928. That v;asn't the first attempt to eliminate poor ■varieties, but it v/as a notev/orthy one. And still there are orchards with varieties no longer profitable to raise. Fuel is scarce. It's an excellent time to use the axe. 2. "No increase ...," In viev; of the present overall situation, it appears that no increase in the total planting of apples and peaches for the country as a v/hole is justified. However, there are local situations which should justify small increases. Some growers may need to increase the size of their plantings to the point where labor saving equipment can be used economically. Twenty years ago there vias talk of Mcintosh being over planted. Yet the number of Mcintosh trees has increased from 240,000 in 1925 to 376,000 in 1940 and Mcintosh still has a ready market in all except the occasional year such as 1942 when a large Mcintosh crop coincided with a large total crop. With better handling and distribution, it should be possible to sell many more Mcintosh than are sold at present. The overall outlook for peaches is one of heavy planting and prob- able over-production in the very near future. Peach plantings in Massachu- setts are at the lov/est ebb since peach growing was started. Good home-grovm, tree-ripened peaches always find a ready market even Virhen the shipped-in supply is large. Therefore, some increase in Massachusetts peach planting seems justified. Since very few pears, plums, and cherries are grown in Massachusetts, plantings of the better -varieties of these fruits could be increased. They should be particularly valuable for the roadside stand trade. 3, "More thought ..,." Notice that this recommendation says "thought and study. ,■». given, .. .to the possibilities." That doesn't mean that every fruit grower should diversify. Perhaps your particular setup, your temperament, your training, your market or any one of numerous other reasons may make it inadvisable for you to diversify, "Thought and study" should reveal this. The word "diversification" should be given the broadest possible interpretation. Thinking of diversification in terms of growing other tree fruits or small fruits is too narrow. Any source of income, aside from the main crop, whether it be running a gasoline station, renting a truck or tractor to the town for road work, keeping poultry, fattening livestock, or selling gravel, should be considered as diversification. Look around you, Vfhat other worthwhile opportunities do you have or could you develop? 4. "Grov;ers are advised ...." The selection of a good site and good soil is highly important, especially with peaches, when one considers that the success or failure of a long time venture depends to a large extent on this decision. In making this decision old conceptions should be cast aside and the farm thought of as a unit. How can the farm be divided up, regardless of present field boundaries, to make the best use of the sites and soils available? The soil conservation service has studied intensely this matter of land use and is in a position to give much aid in working out a plan. 5. "No varieties ...." This may seem like a big order> but it must not be forgotten that the final decision concerning any variety rests with the grov;er, and further that this decision, like that regarding site and soil, will have a very important bearing on the future success or failure of the orchard. The State College and other agencies test varieties and eliminate some which are obviously worthless and make general recommendations in regard to the rest. For a particular set of conditions on a particular farm the grov^er must take all the information available and use it as it ap- plies to his conditions, 6. "Better ...." Fevj- v:ould disagree with this. Massachusetts needs one or more better late winter apples. An apple of Mcintosh quality and season that v;ouldn't bruise so easily would be a great help, 7. "plant ...." Sometimes the temptation to cut planting costs, especially when prices for trees is high, is very great. Buying low grade trees is poor economy because they usually get off to a poor start and never catch up with high grade nursery stock. The chance of getting virus troubles in apples is very slight, because only one virus disease has been reported on apples and it is irery uncommon. No virus diseases of pears have been re- ported. Plums are carriers of peach yellows but are not affected by the disease and show no symptoms. Peaches and cherries, on the other hand, are subject to several virus diseases. V/'ith the increasing use of clonal root- stocks and double working of trees to produce trees with more hardy frame- works, more attention will have to be paid to getting compatible combinations, 8. "An increase ...." The words good grade should be emphasized. Anything has a market this year, but don't forget that green Mcintosh were a problem last year and that in 1942 only U.S. No. 1 could be sold to the gov- ernment. Ijj a big crop year, poor apples are hard to sell even for cider, 9. "Every effort ...." Fruit growing has become during the past 20 or 30 years a more and more highly specialized and complex business. Can this trend be reversed? Can, for example, the number of materials and the number of spraye used in pest control be reduced? A single material applied once a year to control all insects sind diseases would be ideal. Visionary? Yes, but so was the atomic bomb 20 years ago. Simplification is certainly coming but it will take a great deal of effort on the part of many agencies. 10. "The grower ,..." The question may legitimately be raised as to just how much responsibility the grower should be expected to take. Fruit may pass through the hands of several individuals or concerns betvifeen the time it leaves the grower and the time it reaches the consumer. If the grower delivers the fruit in good condition v;hen he makes his sale, doesn't his responsibility end? Hasn't he done his part? In answer to these questions let us ask some others. Wtio should take the responsibility for all the poor and unattractive apples offered for sale in various stores? If the grocer ruins them, isn't that his hard luck? Or if the v/holesaler ruins them, isn't that his hard luck? The grov;- er has received his money for the apples. Is he concerned? Suppose the public won't buy apples but buys other fruit instead, then who suffers? No matter v;ho ruins the apples they are still the product of the fruit growers' sv;eat and toil on which he is depending for a living. If the fruit grower doesn't take more responsibility for seeing that the consumer is offered good apples, who will? — J. S. Bailey POST-VJAR RE-AD JUS TKENTS IN FRUIT FARIvIING Like every other important branch of Massachusetts agriculture, fruit farming will face many readjustments, which, if carried out success- fully, should place the local fruit industry, especially apple growing, in a sound competitive position. The problem of wartime OTerexpajision v^hich may arise in connection with some other lines of agricultural production is not one to trouble the fruit industry. As a matter of fact, within re- cent years in the country as a whole the replacement of old orchards has been on a rather low level. Apple consumption, on the other hand, is at the point where it has already met all its competitive factors and its course promises at least stability, if not some expansion, in line with a generally higher trend in demand for fruit products. V/ith this generally favorable background, the Massachusetts pro- ducers will be able to maintain and even improve their position if they continue proper efforts to organize the industry according to the best methods that are now available both in production and in distribution. From a long-time point of view it is vitally necessary to secure the location of orchards in areas with the most suitable soil and climate conditions. Considerable progress has been made within recent years in soil classification in this state to determine the land best adapted for the growing of fruit. Likewise the lessons of long experience clearly in- dicate the necessity of proper location of orchards in relation to air drainage and avoidance of frost pockets. From the immediate point of view it will be important to keep the orchards in vigorous condition by removal of old trees and sufficient new plantings to provide for both replacements and possible expansion on the more favorable sites. -8- With the general trend toward mechanization in the whole field of agriculture, fruit fanners should also take advantage of possibilities pro- vided by nev; types of machinery, such as light tractors, trucks and electric motors. This should provide for greater efficiency in the use of labor and the possibility of taking care of larger producing units with the same amount of labor. The latest developments in spraying materials and methods should be properly studied and adopted. Much as can be accomplished on the production side of the business, the opportunities for improvement in the handling and marketing of the product are equally great. The advantageous location of the Massachusetta industry in the midst of the greatest consuming area has not been heretofore explored to the fullest possible extent. There is no reason why more Massachusetts apples should not be sold both within the State and in outside areas if more forceful action is taken in marketing the product and if proper methods are adopted by more growers for the grading, inspecting and packaging of the product. In the matter of the adoption of nev; methods of handling and market- ing their product the Massachusetts fruit producers on the v^hole have been more conservative than those in other sections of the country. The natural advantages of the quality of the local product and of location in the prin- cipal consuming region should enable the fruit growers in this State to im- prove their competitive position considerably, if the modern methods of production and distribution are fully adopted and developed. — David Rozman A NOTE OH ORCHARD MANAGEMENT The campaign to eliminate the plow from our list of farm implements is apparently passing into obscurity and our Massachusetts onion and tobacco growers continue to plow their fields. The plow has, for more than 20 years, been practically obsolete in Massachusetts apple orchards. Sod culture and mulching are the most common practices. Liberal nitrogen applications are essential in the sod orchard but we have observed that nitrogen fertiliza- tion of mulched orchards may be injurious after a few years of liberal ap- plication of mulch. The primary objective in applying phosphorus and potash in the orchard is to favor the grovrbh of grasses and other plants needed to maintain soil organic matter. The v/riter believes that it will pay to use a grass fertilizer, perhaps a 7-7-7 formula on grass land outside the orchard to grow hay for mulching purposes. In our experience such a program will generally make unnecessary any direct fertilizer application to the orchard trees. There are doubtless special cases where something additional will be necessary. — J. K. Shaw The strawberry planting should be mulched soon after the ground freezes. It is just as important not to mulch too early as too late. It takes several light frosts to accomplish the hardening of the plants, and fully matured plants can endure a temperature as lovif as 21° F. The mulch should be applied before the temper- ature drops below that level. November 26, 1945 Prepared by the Fruit Program Committee of the Extension Service W. H.

The Present Situation in the Fruit Business WINTER SCHOOL FOR FRUIT GROWERS - January 21 to 25, 1946 This school is intended primarily for experienced fruit growers - for foremen, for skilled workmen, for the orchard owner who wishes to come abreast of recent developments. It will review the fundamentals of fruit growing, but it will emphasize particularly the things that are new. Look for further announcement in December Fruit Notes. iBBued by the Extension Service in furtherstnce of Acts of May 8 and June 30, 1914, V/illard A. Munson, Director, Massachusetts State tollege, Unite- maldehyde, paradichlorobenzene, organic fungicides and wettable spreaders, tight to adequate; practically all others, including pyrethrum and DOT formu- lations, adequate to ample. Exceptions to the stated situation for organic fungicides are as follows: The supply of Fermate is reported (November 12) by the manufacturer to be ample for use not only on farm crops but on greenhouse crops and outside ornamentals as well. It will be available in threo'-^ound bags and 25-pound drums. The manufacturers and distributors of Puratized state (November) that the supply of Puraturf may be adequate for disease control in turfs and lawns, but that stocks of the Puratized Agricultural Spray v/ill be sufficient only for limited use under caref^ol supervision. This spray has proven highly ef- fective experimentally in the control of apple scab in Massachusetts during the past two seasons. Need for Early Orders and Recommendations; Due to the hangover of labor and container shortages, production of fungicides and insecticides is expected to be slow and gradual with distinct interruptions at times. For this reason, the manufacturers and distributors are still requesting that users place their orders as early as possible in order that distributors may know what to ex- pect for their total orders and stocked supplies, and in order to insure an orderly, even flow of supplies from the manufacturers to the retailers, This appears to be particularly important in the case of nicotine and other mater- i^s that are likely to be short in supply. Such materials should by all means be ordered early in the winter so that they will be on hand for emergency use during the growing season. The Agricultural Insecticide and Fimgicide Association also recont- mends and urges that, in view of the increased supplies of new fungicides and insecticides, Federal and State pest control recommendations for 19^6 be issued to farmers just as early this fall and winter as possible. Doing so will permit farmers to estimate their needs and to place orders in ample time for normal delivery. If release of recommendations is delayed until next spring or suxamer, a "rush on the market" for new pesticides may be ex>- pected, resulting in all probability in marked local shortages and unequit- able distribution. -3- Price Outlooki Although manufacturers of fungicides and insecticides have not yet announced prices for the 1946 season, it is felt by some at least that there is likely to be an increase in price for many of the stand- ard materials over last year's figures. Recommendations for 1946s Information on the recommended use« of the newer fungicTdes ^d~irisecticides in Massachusetts for 1946 will appear in this publication from time to time during the winter months, as well as in the revised printed pest control schedules. — 0. C Boyd and A. I. Bournd APPLS BLOOM IN liASSACHUSETTS; 1798-.1849 (Me are indebted to Prof. R. L. McIIunn of the Dept. of Horticulture, University of Illinois, for calling to our attention this interesting informa- tion printed in an old Boston publication.) The blooming period of fruits is one of the records invariably taken by workers who have charge of varietal test orchards. For the most part such records do not date back more than fifty to sixty years. Scattered references in the early proceedings of horticultural societies and early farm papers yield some information, yet it is v;ith difficulty that the year to year per- formance can be gotten for a given location. Just recently I came across an article giving the blO'Oming dates of apples for the years 1798-1849 in Massa- chusetts, so am presenting this data to you. The article, which appeared on June 23, 1849 on page 213 of Volume 1, Number 14, of "The Nev/ England Farmei" (published in Boston), a semi-monthly journal devoted to agriculture, horti- culture, etc. is as follows; "Ilr.

The meaji of the first 26 years, is May 22, nearly; and of the last 26 years, is May 20. The observations were taken when the blossoms had fully expanded, generally, (except some late kinds, as the russets, etc.) and their petals had begun to fall to the ground} (that is, as many petals had fallen as what remained to expand.) "My father, Isaac Stearns, Sen., who was a farmer of Mansfield, took the old Farmer's Almanac, published by Robert B. Thomas, from its commencement, in 1791, till his death, (my father's), in 1837, and carefully noted in the margin of the Almanacs, the time of the blossoming of apple and other trees, with other events, which are to this day preserved in the family, making four good-sized volumes. We have been careful to continue the practice, so that you may depend upon the accuracy of the memoranda. Most respectfully yours, Mansfield, June 4, 1849 Isaac Stearns '^ The editor of the magazine, S. 17. Cole, commenting on the article, said many persons have observed this is the latest season (i.e. 1849) they ever knev/. By the above record it appears that several seasons have been more backward, and one was four days later. In Illinois the almanac is consulted to determine the better time to plant, best fishing days, the phase of the moon and is a place to set down the date when the old grey mare will foal. Massachusetts has gone us one better and made, out of fifty- two almanacs, a four volume set, which we might call "Apple Blossom Time in Massachusetts." REMOVING TREES AITD BRUSH FOR FROST PREVENTION Most fruit growers are familiar with the term "air drainage" and its relation to the occurrence of frost in the orchard; an orchard with good air drainage is relatively free from frost while an orchard with poor or inadequate drainage is the one to get frozen out. Frequently orchards which are located on comparatively high elevations appear to have good air drainage but are damaged by spring frosts. This is sometimes due to a thick stand of trees or brush bordering the orchard on the lower side of the slope which acts as a barrier to the natural flow of cold air and causes it to back up and accumulate in the orchard. The removal of trees and brush bordering the orciiard will often aid in lessening frost injury by allov/ing the cold, heavy air to settle out to lower levels, provided there is a sufficiently large area of low lying ground below the orchard. — Y(.

Tuttle -6- PRQSPECTIVE USE OF DDT AGAINST FRUIT DTSECTS DDT has shown promise for the control of such important fruit-insect pests as the codling moth, apple leafhoppers, oriental fruit moth, grape berry moth, grape leafhoppers, rose chafer, Japanese beetle, little fire ant on citrus in Florida, sucking bugs that cause distortion of peaches, and, in preliminary small-scale tests, some others. It does not appear promising in the control of the plum curculio, orchard mites, or pear psylla, and its value for the control of scale insects and aphids, or plant lice, that infest" various kinds of fruits is questionable. For the control of fruit insects it has, in general, been most satisfactory when used in the form of a water-dispersible pov/der at the rate of l/2 to 1 pound (more often 1 pound) per 100 gallons of spray. It can be used in combination with most of the common insecticides, such as lead arsenate, cryolite, and nicotine preparations, with fungicides such as various forms of sulfur and bordeaux mixture, and v;ith oil. For the control of the little fire ant in citrus groves, the best results have been obtained by spraying the trunks and larger branches of trees with emulsified fuel-oil solutions containing 4 to 8 ounces of DDT and 2 to 4 quarts of fuel oil per 100 gallons of final spray mixture. Detailed recommendations for the use of DDT to control fruit insects are not given here, as for the most part there will be little reason for such use during the remainer of the 1945 season, and more detailed and reliable recommendations can be made when the results of experimental work now under way become available. — A. I. Bourne exferhjents y;ith ddt at maine agric. exp. sta. Some very interesting results have been obtained by Dr. F. H. Lathrop in the control of fruit insects. Dust containing 3^ DDT, 3 applications, (average .59 pound per tree), at each application, on apples reduced the jium- ber of fruit fly egg punctures by approximately 6G^b. The setup was as follows; An old, neglected orchard at Monmouth, Maine, consisting of 69 trees, including 29 V/olf River, was selected for the test. The rest of the trees were Mcintosh, Ben Davis, and a few other varieties intermingled. The dust plot included 43 trees. A small backyard planting of neglected and heavily infested trees ad- joined the orchard on the north. The entire neighborhood was severely infeste»l with fruit flies. (The "fruit fly" of Maine is the same as our apple maggot.) Examinations were made of Vfolf River apples from the dusted trees and from check trees at harvest time. Several hundred apples were examined to as- certain the percentage of apples stung by the flies. Detailed examinations were made of several hundred additional apples to ascertain the number of egg punctures in e ach apple. All of the examinations were cai*e fully made. The detailed counts of egg punctures, especially, were painstakingly made with the aid of hand lens and binocular microscope, in the plot dusted with DDT &,!% of the apples examined were in the "not stung" class while in the check plot ,8^ v/ere in that class. The average niomber of stings per apple in these two plots were i.68 and 25.92 respectively. -7- NOTES FROM DDT_ CONFEREIICE Following are a few notes taken at raradom from the minutes of a conference on DDT held at Horticultural Hall in Boston on October 19 i DDT has no fungicidal value. It is very effective against mosquitoes. Beneficial insects killed by DDT include hymenopterous parasites, lacewing flies, lady beetles (to some extent), and honey bees. It will not control mites, Mexican bean beetle and some aphids. Among scale insects, crawlers are killed to some extent. It is very effective against both the grubs aad adults of the Japanese beetle and against the corn borer. DDT applied April 29 gave protection against gypsy moth for 6 to 8 weeks. Six weeks after application larvae blovm into sprayed plots v/ere destroyed, DDT can be combined v/ith most insecticides and fungicides. Lime probably should be left out of DDT sprays or dusts. DDT is very effective against leaf hoppers and against fall v/eb worm. It is fairly effective against oriental fruit moth although very ineffective when used alone against curculio. There is a possibility that the Food and Drug Admin- istration may stop the movement of apples v/ith DDT residue. DO YOU mm That DDT, if used indiscriminately, may interfere with pollination and may also destroy insect parasites and predators which ordinarily keep cer- tain injurious pests under control? This new material is very deadly against certain groups of insects such as flies and moths and quite ineffective against others. That the small, roundish holes often found side by side in horizontal rows in the bark of fruit trees are made by a woodpecker commonly known as the Yellow Bellied Sapsucker? This bird feeds to a limited extent on the inner bark, cambium and sap of fruit trees although the major portion of its food consists of insects and wild fruit. The amount of cambium consumed is not large . That selective breeding of honeybees is now possible due to the suc- cessful development of a technique for artificial insemination? Improvement of the honeybee by breeding, hov/ever, need not be as slow as in cattle breed- ing because 10 or more generations of bees can be produced during the time require for one generation of cov/s. That, in the larger economy of Nature, insects are beneficial? A prorainei.t entomologist of a generation ago, after pointing out the very bene- ficial effects of various groups of insects said, "If the time ever comes when insects are fought to the extent recommended by some economic entomologists, there v/ill be as a consequence a great economic disaster due to the scarcity of insects. That the 8 important commercial apple varieties in British Columbia include three common New England varieties (Mcintosh, Delicious and Yfealtliy)? In addition, the British Columbia list includes Rome Beauty, Newtown, Jonatiia«, Vfinesap and Stayman. -8- That fruit prices fluctuated widely after Tforld War 13 On Armis- tice Day in 1918, orsinges for example, were quoted at 51.5/ per dozen. By the middle of 1919 the price had dropped slightly to 5l/, but by the middle of 1920 it had soared to 71.8/ per dozen, and later in 1920 it crashed to 43.7/. It is to be hoped that history will not repeat itself. That bees may go a mile and a half or more from well established . colonies in search of nectar and pollen? In a California study, honey-bees constituted 62^ of the blossom visitors in a pear orchard, and one bee -visited 84 pear blossoms to obtain its load of pollen. It was estimated that on a good flight day, 822,720 bees issued from 16 colonies in one pear orchard. Strong over-wintered colonies surpassed package bees in population, flight activity and amount of pollen gathered. That a helicopter is being used successfully in the dusting of more than 4,000 acres of vegetables on muck soils in Michigan. One big advantage is found in the fact that a helicopter may be used v/hen the soil is too wet for an ordinary sprayer or duster. The time nay not be far distant when a helicopter will hover over Mass, apple trees as a humming bird hovers over a flower. That tablets containing vitamin G will improve the color and flavor of h'lae canned peaches, pears and plums? In experiments conducted at the Mass. Agr. Exp. Sta. it is found that the cost is less than 2/ per pint jar at pres- ent Gelling prices of tablets at drug stores. Vitamin C acts against oxida- tion thus preventing darkening and change of flavor in fruit at the top of the jar v/here it comes in contact with the air. That 44 million cases of canned fruits and fruit juices, excluding citrus, will be available to civilians during the 1945 marketing period, com- pared with approximately 33 million cases in 1944, and 43 million cases in 1943? Because of reduced government needs, set-aside requirements for canned fruits and fruit juices other than citrus have been terminated. That the carbon, nitrogen, sulfur, and other atoms which make up the living v;orld of today are the same identical atoms v/hich formed the living world of a million years ago? This striking comment is found in a recent book, "Microbes of Merit." According to the author, our own bodies may consist of some of the identical atoms which once were part of a dinosaur, or of one of our ovm ancestors. Only the pattern has changed. The same clay is cast in ever changing molds. That alloys of magnesium and aluminum make ladders lighter and more lasting than wood? Twelve-foot ladders designed at Y/ashington State College weigh approximately 11 pounds less than similar ladders made of wood. That, in a fertile soil, about 90jJ of the roots of the strawberry plant are in the upper 6" of soil and nearly 75/o are in the upper 3"? With- in this limited depth of soil a strawberry plant is a heavy feeder. It is estimated that about 1^0% of the immediately available mineral elements are found in the plov/ slice, or darker colored surface, layer. -9- That the total holdings of apples in cold storage in the U. S. on November 1 were about 60^^ of the holdings one year ago? In spite of this fact the State of Washington actually had more apples in storage Nov. 1 of this year than it had a year ago (10,958,000 bu. as compared with 8,910,000 bu.) The totals in the U. S. were 30,858,000 ('44) and 18,515,000 ('45). That about 19,000 farmer ovv-ned and farmer controlled cooperative associations and mutual companies nov/ operate in the U.S.? More than 10,000 are engaged in marketing farm products and purchasing farm supplies. An es- timated 3 million farmers hold membership in these organizations. That agriculture in the U. S., as measured by the value of its goods, grev/ from a 49 billion dollar industry to a 70 billion dollar industry during the four years ending January 1, 1944? During these four years the equities of all owners of farm land and of tenant farmers appear to have increased nearly 7 billion dollars. That German Prisoners of TiTar were an important factor in harvesting the scattered apple crop in the Nashoba area this season? The total number of man-houis amounted to 54,691, and the net bill paid by 37 growers v;as $31,297.10. The largest number of man-hours in any one orchard was 6,624, vihile in four other orchards the total was in excess of 3,000 men-hours. That a red Bartlett pear has appeared as a bud sport on a tree in Washington? Because of its bright red color it is believed to have market possibilities. A second generation tree bore a crop of these unusual pears this season. That nearly 90^ of the available nectar produced by flowers in the U. S., goes to v;aste? It is estimated that there are only about 5,219,000 colonies of bees in this country. FROST PREVEIJ_TI0N IN THE ORCHAED. A bulletin on frost prevention in the orchard is in the initial stages of development. To make this bulletin of more value to Massachusetts growers, vre should like to have information on experiences of growers, successful or otherv;ise. Some points v/hich would be of value include (1) the type of heating equipment used, (2) number of heating units used per acre, (3) niomber of degrees temperature was raised, (4) at what temperature were fires started, (5) did the heating pay, and (6) approximate cost per acre. Any experience which you may have had in protecting your orchard from frost v/ill be greatly appre- ciated. Just drop a card to If, D.

In a recent Experiment Station report we find the following Interesting conclusions* (1) Solid boxes restricting ven- tilation shovr promise as a means of reducing water loss of apples during stor- age. (2) Pre-storage treatments of R.I. Greening apples with high concentra- tions of carbon dioxide give promise of controlling storage scald. -10- THE PRESENT SITUATION IN THE FRUIT BUSIHESS Y^here soil and site are favorable there is reason to be optimistic about fruit growing in Massachusetts, although the v/ar years have left many- fruit enterprises in a "dovm at the heel" crondition. Shortcuts and neglects have created problems which need prompt attention. The short apple crop of 1945 resulted in a greatly curtailed spray prograia in many orchards, with a resulting buildup of apple maggot, curculio, codling moth, and apple scab. This condition must be faced next spring if the prospective bumper crop is to be brought through in good condition. Labor has been scarce and many growers have done only enough to "get by". A few growers have done remarkably v;ell, however, in overcoming handicaps and are entering the postwar period with very promising prospects. High prices during the past three years have brought a decided decline in apple grading. It might be said that grading no longer exists in this state since the most mediocre type of fruit is likely to sell at the coiling price. This condition cannot continue. ■"iniile orchards have grown older, nev/ plantings have not kept pace with orchard decline. Yh are not planting a quarter as many trees as are need- ed in commercial orchards to maintain plantings on a proper age basis. It is not a question of nevfcomers planting fruit trees, but rather of already estab- lished growers rejuvenating their present plantings by cutting out older blocks and planting new ones. The tovm of Kardwick which 35 years ago was an important apple export town is an excellent example of what happens when apple growers fail to plant trees. A shortage of good nursery stock at a reasonable price is partially responsible for the failure of growers to replant. The spring of 1945 v/ith its frost on April 23, teaches an important lesson as regards future plantings. Favorable sites, that is, areas relatively high with respect to the immediately surrounding country, must be selected for future plantings and varieties must be so distributed as to provide nearby pollinizers for the Mcintosh variety. All over Massachusetts we have observed cases this season where Mcintosh trees next to good pollinizers have borne a good crop while trees more distant from pollinizers bore only a scanty crop. Bee flight was so limited last spring as to emphasize the need for nearby pol- linizers. On most fruit farms there has been a tendency to plant open fields with little or no regard to air drainage. This practice must be discontinued. Numerous orchards nay be cited in v;hich a particular block bears only now and then because of frost damage, while other blocks are bearing 500 bushels of apples per acre per year. Selection of soil and site for future plantings arc of utmost iiiiportance. During the past two or three years at least 50 commercial apple grow- ers in Massachusetts have made a start in the removal of crowding filler trees, or in the removal of older blocks of trees. This practice should continue, since many of our applo orchards are now in the 30 to 40 year class where se- vere crowding is apparent. The apple business would be on a firmer basis if every commercial grower vrere to follow the example of a few of th" more pro- gressive growers. Removal of older trees and crowding trees as well as unwant- ed varieties, and planting of young trees on good .soils and sites by grov/era now in the business, are strongly recommended. — ■ <■' iSil: •"ft-..* ^§^ 'i«i .vi^ /« December 31, 1945 Prepared by the Fruit Program Committee of the Extension Service V*'.

NE\T FUNGICIDES FOR FRUIT DISEASES During the recent war period, considerable headway was made by various manufacturing concerns in the development of new organic fungicides. Some of these have been tested repeatedly on apples and other fruit crops. A limited number of then are considered both effective and safe when in- corporated into our fruit pest control schedules. Others, while effective fungicides for certain major diseases, are either not safe to the plant or they present handicaps regarding compatibility with certain other stand- ard materials commonly used in combined' spray mixtures. In other words, they are still in the developmental stage and require more experimental Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, Vfillard A. Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. -2- work in laboratory and field before they can meet the requirements of a standard fungicide. Fermate (Ferric dimethyl dithiocarbamate ) . This black, soot-like powder has""b'een~sub jected to experimentation and field trials for several years, and is now recognized as a standard fungicide for several fruit diseases. J-fc is given full recognition in the 1946 apple spray chart. Fermate may be used either as a spray or a dust. It is compatible with all other common spray materials including summer oils, except lime and copper. Although lime does not reduce its fungicidal value, it reacts chemically with Fermate to form a more soluble compound that may injure various crops/ Fermate is particularly compatible with sulfur, appearing to be benefited by the sulfur as well as stepping up the fungicidal value of the latter, but it should not be mixed v;ith copper, Fermate, either in dust or spray form, is a decided specific for cedar rusts on apple and quince. It also acts as a safener for arsenical injury when combined with lead arsenate. Fermate is as effective as or better than wettable sulfurs for the control of scab and black rot of apple and pear, also leaf and fruit spots of pear, and it is much safer for those crops as regards fruit russet. It likewise is as effective as standard copper sprays, with much less injury to foliage and fruits, on apples for control of blotch, Nev; Hampshire fruit spot, and bitter rot. Fermate is as effective as Bordeaux mixture or copper dusts for black rot of grapes; the equal of sulfur, and with less injury, for cherry brown rot and leaf spot. It is considerably superior to Bordeaux and other copper sprays for the control of cranberry fruit rots. V/hile Fer- mate is effective against peach scab and brown rot of stone fruits, it is not considered safe for tender peach foliage. In 1946, Fermate will be available in three-pound packages as v/ell as in 20-pound drums. The spray deposit is improved at least on some crops by the addition of a moderate amount of spreader. Fermate should be made into a slurry or water suspension before it is added to the tank, preferably by pouring the mixture, v/ith the spreader, repeatedly from one large pail or can into another. At the prevailing price of 60 to 70 cents per pound, Fermate may perhaps be employed most economically for control of cedar rusts and as the standard fungicide on russet-susceptible varieties such as Baldxvin, Delicious, etc, Puratized N5-E (Phenyl mercuri triethanol ammonium lactate). This complex organic compound occurs in true solution, and has been used extensively by the U.S. armed forces for mildevir-proof ing various kinds of cloth and other fabrics. It is considered compatible with arsenicals, nicotine sulfate, fish oil or linseed oil, but not with lime. There is some question whether it is compatible with summer oils, also with hard water, and with sulfur and when following sulfur sprays. It is considered at least as effective as the best wettable sulfurs in preventing apple scab and black rot; also the equal of limo-sulfur in burning out apple scab leaf spots without causing any injury whatever to the foliage or fruit. The principal handicap for Puratized is the extremely small amount of mercury it contains. As long as there exists no set tolerance for this -3- highly poisonous metal on fruits and vegetables, the material must be used in such a manner as to preclude any mercury residue on the harvested crops. Analyses made of apples spra^'^ed by Puratized in 1944 and 1945 indicate a detectible residue of mercury when the spray was used throughout the season, but none when the spray was discontinued after the first cover spray. If Puratized is used on fruit crops, it should not be included in the schedule later than the oalyx or first cover spray. The supply of Puratized is still limited, and the manufacturers indicate that it will be plentiful in 1946 only for limited use under care- ful supervision. It vjill be sold as Puratized Agricultural Spray, and the stock solution v/hen diluted in the spray tank at the rate of one pint to loo gallons will give a concentration of the active ingredient of 1:15,000'. Isothan Q-15 (Lauryl isoquinolinium bromide). This is one of the recently developed quartenary ammonium derivatives that has given consider- able promise in the control of apple scab and the leaf and fruit spots of pears. It, like Puratized, is vifater-soluble ; it possesses a high degree of inherent vretting and spreading qualities, and it is not supposed to be poisonous to higher animals. In tlie spray test at the College this year, (^-15 fell dovm badly in apple scab control, and when combined with lead arsenate the spray mixture caused considerable fruit russet and pronounced late season leaf burn characteristic; of arsenical injury. Isothan Q-4 is a close relative of ' — (D U3 k! to d x; o -H «) C; i-l i-i rH 3 O O 03 to o r-i w >H tn^-^ — ■ © -P r/i fi C S O rt ® 03 « ^H r-i ,-1 t:3 -P O aS ii . o o «>, o o m -P si C x co-P si fl si ^■M ^-s U IS ID tH & "-< ^t s ^ w -P CO d ^ ^ w -p CO 0) 5 o5 (T 3 y< O 5 s5 ^ ^ U O u > a) a to > i-l 5 -H w ^ -^ ^•H tiO £ p^ O X) bO o cu O tJ tl O -H bJO-J U tax) O-rH iifl'Ci u t-Oi:!

Some growers failed to answer the question in column 2 and others tvnsvjered it only with the idea of adding to their pres- ent plantation wiiioh will explain why the figures in columns 2 and 3 do not total that of column 1. One other point which ijhe survey brings out is the attempt of many growers to choose varieties which will extend the harvesting and marketing seasons. This is particularly true among those growers Who now have large -3- aoreages of Mcintosh. Growers are beginning to see the folly of a one variety orchard. There were too few returns of the peach and strawberry question- naires to give any detailed report, but they did indicate some interest- ing trends. The peach survey shows that Elberta is still the leading peach variety v/ith Golden Jubilee a close second. Halehaven ranks a good third with J. H. Hale a poor fourth. Of the newer varieties, Summercrest and Triogem appear to have made a hit with some growers. Strawberries show a reversal of form with the old standby Howard 17 losing first place to Catskill, although it is still a strong second. There are not any other varieties which show much strength, except Sparkle, a new variety, v/hich looks as if it may find a place in the variety picture. ~ W. D. V^'eeks BLOSSOM THIOTIING SPRAYS The prospect of a heavy apple crop in 1946 and a light crop in 1947 has focused attention on the possibility of using blossom thinning sprays to reduce the 1946 crop and possibly increase the 1947 crop. Un- fortunately, we know too little about these sprays to warrant recommenda- tion for general use. Some growers have used them with good success. The on-year crop of biennial bearin-; trees has been reduced and at the same time fruit buds for the succeeding year's crop have been fonned. Others have had less success. Elgetol has been the most used. \'Je were able to reduce set by spraying at full bloom with the usual harvest sprays last year, but the season was abnormal and we do not yet knov/ what the effects will be. Suggestions and directions for grovrers desiring to ex- periment with blossom thinning sprays are being prepared and will be sent on request. ^ ,^ _, ~ J. K. Shaw COATING BEES WITH POLLEN From time to time the question is raised concerning a device for coating bees with pollen as they leave the hive to fly to the trees. Such a device was made in the early 1930 's by Burrell and King. They reported that the method held promise. Later workers have abandoned the idea, feeling that greater return would result from more emphasis on the use of strong colonies of bees. Present knowledge would seem to support this view. VJhether anything of a practical nature could be v/orked out in conjunction with the pollen traps now available is problematical. Until v/e have definite information, it would not seem advisable from a practical standpoint to shift from the present suggestion that strong colonies be used for orchard pollination, — F. R. Shaw WALT DISNEY'S next movie will be "JOHNNY APPIESEED," it is reported. THE APPLE SCAB OUTLOOK The number of scab spore cas wintered leaves is abnormally large heavily scabbed leaves. In the Coll and fruit bud development are approx date (March 26) last year. TJ'ith Mc stage, about one-fifth of the old sc maturity in a small percent of the p thecia contain either no spores at (ascospores). es (perithecia) developing in the over- this spring due to the abundance of ege orchards perithecial development imately the sane as they were at this Intosh fruit buds in the silver tip abbed leaves show scab spores reaching erithecia. The remainder of the peri- all or only immature winter spores Scab spore development in one South Amherst orchard is in the same stage as here at the College, while in another orchard perithecia are con- siderably less advanced. The most advanced stage of ascospores so far ob- served was in a leaf sample from Yfallace Pratt of Bridgewater (Plymouth County) where 10/J of the leaves showed a goodly number of mature spores at the sv;elled bud stage (llarch 19). Had it not been for the very dry v;eather during the past week of mild temperatures, scab spore development would be even farther along than it is now. Should cool, wet v/eather prevail in the near future, scab spores will develop much faster than fruit buds. If the present kind of weather (v/arm today v/ith showers predicted for tomorrow) should last for several days, a small portion of the ascospore supply will be ready to shoot by the time the fruit buds reach the green tip to early delayed dormant stage. Last year at this same date and corresponding fruit bud stage, the weather turned very \^arm and remained so for a full week, bringing fruit buds in Amherst into pre-pink by April 5. It is hoped, of course, that such will not be the case again this year. The accompanying table indicates the time of season in past years when Mcintosh fruit buds in Amlierst reached the silver tip stage, and the corresponding stages of scab ascospore development; also when ascospoxes were sufficiently matured to discharge in the orchard during each of rthose years .

Our records over the past sixteen years in- dicate that this situation is not dangerous, even in Mcintosh, because under such conditions scab infections either do not occur or are quite unimportant. Hov/ever, if ascospore development is abnormally advanced, v/ith possible heavy discharge during that bud stage, it is advisable to include a copper fungicide or Fermate in the oil spray, particularly if tha* spray is applied at the late delayed dormant stage. Enough Bordeaux powder, or a neutral copper fungicide, is added to give two pounds of metallic copper to 100 gallons of the oil spray, or 1-g- pounds of Fermate may be used. As has been emphasized time and again this v^^inter, this is one of the seasons occasionally encountered when it is considered highly advisable for many apple growers to apply a ground spray of Elgetol (-g- to 1 gal. in 100 gals.) to reduce to a minimum the unusually heavy carryover of the scab fungus before very many of the ascospores reach maturity. This spray should be applied so as to wet all of the old leaves on the orchard floor including those along the borders, and at the rate of 500 to 600 gallons per acre. Any time now through the delayed dormant stage would be appropriate for the Elgetol spray, although care should be taken to avoid its drifting to the green leaf tips. Such a spray would not only eliminate the need for a fun- gicide in the delayed dormant oil spray on the trees, but it v/ould permit the grower to proceed with his regular sur.imer spray program vdth much more confidence in his effort and ability to prevent scab infections than would be the case if the huge, initial supply of scab spores were present. This sane spray of Elgetol may be used to advantage on the floor of the peach and plum orchard for brown rot control, and of the vineyard for black rot. However, the spray should be prepared at l^o concentration. — 0. C Boyd Yjm SOIvIE APPLE TREES GROyf TOO TALL Abnormal height in an apple tree may be due to one or more of the following causes: (1) crov/ding from closely adjacent trees, (2) lack of production, (3) two or more "leaders," (4) unwise heading back of top, and (5) variety. These five factors are arranged in approximately a descending order of importance. Let's examine them separately. (1) The closely planted orchard v/ith its gradual loss of lower limbs, results in tall, trees because they are continually trying to overtop their neighbors to maintain their "place in the sun." In other v/ords, the trees must grov/ upward because they can't grov/ in any other direction. Nearby buildings or shade trees have a similar effect. (2) A good spray prograr.i tends to develop a drooping type of tree. The downward pull of 10 bushels of apples brings many of the branches to a horizontal position or lower, while a peck of apples on the same tree would permit the branches to grov/ upward. The average backyard tree is tall partly because it lacks this earthward pull. -6- (3) Double, triple or multiple tops, particularly if accoinpanied by a scanty crop of fruit, result in a taller than nonaal tree. Here we find competition betT./een competing leaders similar to that between adjacent trees in a crowded planting. Each leader tries to overtop the other. (4) V/e have all seen tall trees which the ovmer tried to lavier by what we might call "high level topping." This may stimulate a tremendous growth of sprouts v^hich make three or four feet of annual growth because they are replacing very vigorous, advantageously located branches. By the time these new limbs bear fruit the tree is not only taller than before but the nev/ branches are too stiff to be bent dovmward appreciably. The result is an extremely tall, dense tree, (5) A Northern Spy or an Early Mcintosh tree has an upright habit of growth while a Rhode Island Greening or a Cortland is naturally more spreading. Even so, a bearing tree of the former varieties, assuming a good framework and ample spacing, will begin to droop and remain within reach if it comes into early production. If »all of the above mentioned factors • are as they should be, there will be no need to worry about a source of 20-foot ladders , or of pickers sufficiently courageous to climb them. SOME EARLY SPRING TIPS FOR FRUIT GROVreRS 1. Lime. Anyone applying ground limestone in the orchard this year, should insist on getting high magnesium or dolomitic limestone. Our soils are inclined to be low iiT'magnesium. High magnesium lime is the cheapest way of avoiding a magnesium deficiency. 2. Apple Scab. There is an exceptionally heavy carry-over of apple scab in many Mcintosh orchards this spring. If the month of May is as rainy as in 1945, Mcintosh growers will have a real fight on their hands in preventing scab infection. Scab spores are maturing early, A ground spray of Elgetol will help to solve the problem. The Pre-Pink and Pink sprays will be very important. It is easier to prevent a scab infection than to check it after it becomes established. 3. Bridge Grafting, Mice have damaged many fruit trees in Massachusetts during the past winter. It will pay to look over every tree where the grass is at all heavy. Trees surrounded by heavy grass are not only more subject to mouse injury, but the damage is likely to remain unde- tected. If bridge grafting is needed, well matured, flexible growths of last year should be cut while fairly dormant and kept in a cold, moist place. Bridging is most easily done about the time the leaves appear. 4. Tree Framework. The critical period in the development of a framework in a fruit tree are the second and third years. Fruit trees which were set either last year or the year before should be looked over this spring, V/eak crotches, competing leaders, whorls of branches, and other symptoms of a poor framework should be corrected now instead of waiting until the trees are older, when larger cuts will be necessary. -7- 5. Raspberry Spur Blight. Two troublesome diseases of raspberries, spur blight and anthracnose, may be controlled by properly timed applications of Fermate. These diseases are an important factor in reducing rasp- berry yields. Anyone interested in the control of spur blight and an- thracnose will find full details in February Fruit Not'js. 6. Bloesom Thinning. Any apple grower interested in applying a blossom thinning spray to reduce the set of fruit in 1946 may obtain some prac- tical suggestions by writing the Department of Pomology, M.S.C, Amherst, Mass. Although this practice cannot be generally/ recommended, it has possibilities and may v/ell be tried on an experimental basis. MICHIGAN ELIMINATES INFESTED FRUIT TREES A new law became operative in Michigan September 6, 1945 which will be of much benefit to the fruit industry. Following is a quotation from a letter recently received from C. A. ^ Boyer, Chief, Bureau of plant Industry, Lansing, Michigan: "Our fruit growers and nurserymen in the state realize the necessity of giving more adequate protection to the fruit industry which shows an aiinual income of some $35,000,000. Since this program was instituted following the passage of the law, we have eradicated some 85,000 fruit trees and may I relate it is just in its infancy. It is our intention to have sufficient personnel, equipment snd moneys to see that every fruit tree in the fruit growing area is either properly cared for or removed . "It is interesting to note that we have been hiring bulldozers to re- move these large apple tre^s, and the cost is about 12^ on apples > 9^ on cherry and pear, and as little as 5/ on peaches. They did a com- mendable chore in removing trees. YIe likewise make our regular in-^ spections for virus diseases at the proper season of the year, and are instrumental in having growers remove virus diseasetJ peach trees. If you have any questions concerning the same, please feel free to call."

By the time this issue of Fruit Notes is re- ceived a new mimeographed leaflet No. 134, "Frost Prevention for the Orchard," by YI, D. Weeks will be available. A copy may be obtained from your County Extension office or from the State College. It tells the conditions under v/hich frosts occur and offers some practical sug- gestions. If it were easy to insure against frost damage most growers would do something about it. For an orchard in a frosty location, how- ever, preventive measures are both expensive and laborious. HOUSING for orchard workers will be the key to the labor problem, 36 mem- bers of Yfenatchee Farm Vforkers Housing, Inc., agree. They plan to enlarge a $25,000 housing facility which started as a tent camp, adding new build- ings. (Adequate housing at harvest time is also a critical problem in Massachusetts.) Boron Deficiency in Massachusetts Soils. Dr. F. E. Bear of Rutgers Univer- sity states that crops grov/ing on Gloucester, Merriraac, and V/ethersf ield soils are frequently benefitted by borax applications. These soils are all found in Massachusetts, Dr. A. B. Beaumont, State Conservationist for Massachusetts, advises that most of the outwash soils in Massachusetts are likely to need borax.

A few days' delay in mimeographing and mailing this issue of Fruit Notes is due in part to a heavy volume of work in the Mailing Room and a small staff plus a few part time student vrorkers . Besides many individual releases. Fruit Notes is only one of several regular publications to go through the mill." if it is held up temporarily we console ourselves by knowing that something of an emergency nature has priority, or perhaps the anticipated student assistance didn't materialize.

V/ithin a radius of 75 miles north and east of Biarritz there is little other than home orchard trees and the ever present small vineyard for local wine production. Open grown trees, usually in sod, are typically very high headed, little pruned and make slavr growth. The fruit from such trees is used chiefly for cider although some of the best (about a U.S. Utility Grade) will be found on the retail market as mixed lots. In the Gironde Valley running from Toulouse to Bordeaux, fruit growing is one of the major typos of farming. Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, Willard A. Munson, Director, Massachusetts State College, United States Department of Agriculture, and County Extension Services cooperating. -2- Mixed tree fruits with some American apple varieties predominate around Montauban, plums at Agen and of course thousands of acres of grapes around Bordeaux. In this valley the soil is usually cultivated, but frequently the trees are very low headed, open center or goblet and very severely pruned. The V/ar Period with its shortage of fertilizers and spray materials as^ well as tools and labor, has been pretty hard on the French fruit grower, but at best their methods and knowledge of pest control as well as most other practices are years behind what \ung flov^-ering crab tree in Amherst with a snowball bloom has one sprout which grev/ 7g- feet in 1945, It evidently continued to grow until late fall evidenced by the killing back of 6 inches of th^j immature tip. And yet there were blossoms on the sprout v;ithin 10 inches of the tip, v/hich vrare probably initiated in late September or October because that particular wood didn't exist before the first of September, -T- An Odd Blackcap » In the crotch of an elm tree on the M.S.C. campus, about 8 feet from the ground, is a blackcap plant which thrived during the 1945 season and gives promise of bearing fruit this summer. The plant probably started from a seed dropped by a bird. If it is able to fruit in so hopeless a location, it is a reflection on a grower if he fails to get results with plants growing in a good soil, Ammate Affects Apple Leaves, Several orchards are showing a peculiar yellowing of the leaves v/here nearby poison iv^"- was sprayed with Animate last summer. On young trees, half of the leaves may be so affected. The yellov-dng, unlike that in magnesium deficiency, is confined to the veins and midrif of the leaf giving it a mottled appearance. If a spray intended for poison ivy reaches many of the leaves of the tree, the results may be disastrous. Scab Eradication. Never before have we seen such widespread infection of Mcintosh trees. Even in well sprayed orchards an occasional scab spot can be found vfhile others are so hopelessly infected that further fungicidal sprays are of doubtful value. Everybody is interested in using Puratized or lime sulfur and many are applying one or the other. The results seem to range from near failure to perfection. The former may be explained on the basis of poor coverage or infections not evident v/hen the spray was applied, Amateurs viho had someone spray their trees only to find that the leaves dried up v.'ill no.turally bla me the spray instead of the already ruined foliage. TEN YEARS OF FRUIT NOTES Our monthly publication had its beginnings about the time of the 1936 flood. The first issue in our file is dated March of that year. In the intervening years we have touched on a fairly wide range of fruit topics without attempting to give all of the details. If Fruit Notes has accomplished anything more than serving to remind readers of new develop- ments, it may be along the line of emphasizing such fundamental things as better spraying, correcting magnesiu:n deficiency, pollination and orchard management. Any reader with an idea v/hich nseds to be presented is invited to send his suggestions in writing to the "iditor, STRAFreERRY "IWBBINS" Undersized strav;^berries with hard undeveloped tips are of co:nmon occurrence particularly in beds tv/o or more years old. Many expl conations are offered such as frost and poor pollination, which may have no relation to the problem in a particular planting. Self fruitful varieties soldom suffer from faulty pollination. In fact, a number of obscure little bees are generally active while strav^^berries are in bloom. And if an insect crav^ls over a blossom at all, it would be most likely to contact that part which becomes the tip of the berry. Frost, too can be discounted because "nubbins" come mainly from nidseason or later blossoms, not from «8. the first blossoms, YJe therefore offer this possible explanation. It takes grod roots and good leives to produce good borries. The poorer the root system, the more ha:idicr.pped the l3avos a"d the less of needed materials will the beri-ies o.a taat plant reocivse The tip of the berry is farcnest reii.jved fr<.Jri the source of supply.

This suiraner two such trips are planned, the first of which got undon/ay June 23, As this is being written the creY/ consisting of A, P» Frenc'h, 0. C.

It makes possible the purchase of trees which vd.ll bear fruit of the desirod variety. It has practically eliminated the sale of misnamed trees in the East, The list of nurseries v.rhich avail themselves of this service may be obtained from the Pomologj^ Department on request. SCHOOLS FOR IiAR\^ST LABOR SUPERVISORS P LAMED To facilitate the handling of inexperienced apple pickers, at least two sessions with picking crov» foremen in V/'orcester and Middlesex Counties, during the late summer are being planned. It is not the intent of these schools to urge uniformity in picking methods, but to cover the many items which contribute to a smoothly running harvest. The schools will be limited to actual or prospective foremen of picking crows, ITatch for announcement of dates and places of meeting.

Within three years we nay even find an over supply of certain trees particularly peaches. One nursery plans to bud a million peach trees this summer and enough of other fruits to bring the total up to two million. Ve may even find, within five years, gome sizable brush piles of unwanted stock. Misnamed Trees Much Less Common, While an occasional mixup is almost unavoidable in view of the inexperienced help, the need for getting budwood from a number of sources, etc*, it is gratifying to know that most nurseries are keeping a close check on their budding operations and have the rows well labelled. Large scale mixtures, such as the Wolf River-Mclntosh deal of a generation ago, are fortunately a thing of the past. Plums on Peach Boots. It is a common practice among niirserymen to bud some of their plums on peach seedlings instead of plum seedlings for planting in light soils. Such trees are more likely to thrive since the root system of a peach tree seems better adapted to a sandy soil than that of a plum tree. Japanese Beetles Show Preferences. In certain nurseries where the Japanese Beetle is a menace, as for example in Maryland axxd Virginia, some fruit trees are heavily attacked while others nearby are quite generally avoided. Sweet cherries and plums are among the favorites and certain varieties seem to be preferred. An occasional tree of apples or peaches in the nursery row may show a large colony of beetles, vith 50 or more on a single tree. DDT is being used quite effectively. A ITursery Oddity. The 5-in-l tree, so highly praised in the advertisements, is an easy means of getting the amateur's dollar (and then some). But one nurseryman expressed his private opinion that it isn't laioh of a tree. Espalier Peach Trees. In one New York nursery, peach trees in considerable numbers are trained by attaching part of the branches to a fan shaped s\q)port, A group of Italian women were dexterously preparing these trees for the would-be fruit grower vho wants to be different even though he must pay five dollars for the privilege. Trees Respond to Poultry Manure. In one nursery where trees are making excellent growth it is a common practice to fit the soil by applying a liberal coating of poultry manure sowing soy beans to be plowed under when about knee high, A striking comparison was observed where the supply of poultry manure gave out and one side of the block was left unfertilized. The trees were about a foot shorter in that area* OORHEOTIOIT; A mistake was made in the title of the first article in June rruit Notes. It should have read "The Unusual Bloom" instead of the "The Annual Bloom," The writer's scribbling was at fault.

On closer exar.iination it v;as obvious that there were both red apples and green apples on the saiae branch. And when a few apples of each kind were cut to expose the seeds, the red apples v/ere found to have, on the average, fewer seeds thai the green apples. This is exactly what one would expect since each seed acts as a little punp in bringing ivater into the apple. An apple vdth 8 seeds stands a nuch better chance of getting its full quota of water than an apple with 4 seeds. And v;hen s^)me of the apples feel the pinch of co;-.ipetition nature has a way of shedding the unfit. Until the rain of July 22, a severe drought had not only caused lawns to turn brown; it had greatly retarded tiie gr'^vrth of apples on dry soils. When the roots are unable to take in enough water to supply the needs of every leaf and apple, thoy becmo strong c lunpotitors vsid, strangely enough, the leaf exerts nore of a pull than the apple. In the ab')ve mentioned orchard, if all of the reddening apples EUid at least half of the green apples had been removed, the pr 'blon would have been solved. It was siraply a case of a large number of apples clamoring for water, and there v/asn't enough to go around. To make natters still worse the trees in this orchard have more branches than they need and the trees arc themselves crov/dod. So it sinu-iers down to a matter of too nony apples, too r,uiny liiabc, and too laijiy trees to pemit the development of normal apples in a excessively dry suraiaer. The result is likely to be a large proportion of 2 to 2-|- inch apples instead of 2 3/4 to 3 inch. Cherr^'' Picking Record. A -Tiigrfint worker in Hood River, Oregon is reported to have picked 2168 pounds of cherries in a 12-hour day. It gave hii-i a record - also ^75,84, Pickers generally average ;i;8 to ^1^14 a day. *4« YffiY EASTERLY VJINDS? (TfhGn the air over a large area in the United States becomes heated, there is developed a low pressure urea which tends to move toward the east due to the motion of the earth* This often brin{;s an east wind, and rain. Director H. A. Bostrora of the Essex County Agricultural School gave this further explanation of the occurrence of east winds, at a recent twilight Eieeting,) "Matters of lari^e economic importroice, or having very much bearing upon our personal comfort, sometii.ies seen to rest upon comparatively insignificont things. Take for example the light easterly winds which seem to dominate the daily climate in the spring and early sumiaer months along our shore. Often we v/ish there vrere not so much of itj other times we are exceedingly glad for the light breeze that penetrates, sometimes a mile or two, sometimes a t;ood many miles inland, to prevent what would otherwise be an unbearably hot day, "Yvhen one measures the amount of heat v;hich is required to raise the temperature of the various kinds of materials, -me finds that it takes a great deal more heat to warm a unit of water through one unit change of temperature tluai it does any ■-•ther of the comi.ion substances, such as rock, soil, wood, etc. Said in another way, this means that the temperature of Icaid areas will rise more rapidly from a given wTiount of the sun's heat than will the temperature over the ocean. Consequently, the air over the land areas, war:.is, expands, and rises more rapidly than it does over large water areas, which creates a nove:.iont of the cooler air from over the ocean imvard over the land. The difference may be slight, creating -July a very light breeze, felt only along the shore, or there nay be enough difference to cause the air to move inland a considerable number of miles, "In weather, no such siiaplc explanation is entirely correct. To quote the Agricultural Yearbook for l94tl (Climate .vrid Man): 'It is more correct to emphasize that the upper layers of the cean are nearly always in a state of violent stirring, whereby heat losses or heat gains occurring at the sea surfo.ce are distributed through the large volumes of water. This mixing process sharply reduces the temperature contrasts between d ay and night and between winter osid summer. In the ground there is no turbulent redistribution of heat and the effect of molecular heat conduction is very slight. Thus violent c.^ntrasts between day and night are created (inlfoid) '• "The vj-riter thus points out that sharper contrasts in temperature are bound to occur over laaid areas than over the water. The ultimate effect is a sharper, quicker rise in temperature over land area- thsoi over the v/ater, resulting in the cooler air fr-'-m the water moving in towards the warmer inland areas, "Vt'hen we as students sat in a class in physics and studici the specific heat of solids, liquids, and gases, most of us found it pretty dry material and we didn't care whether water or iron or stone or some other substiuice had -5- the grccitost heat capacity. Most of us ri>_,ht new vrould be j^lad to feel tho breeze that results from such a physical phenomenon.

A few days ceo a grower raised the question "Shall I apply nitrate of soda now to my Mcintosh trees which have practically lost their leaves because of scab?" He had in nind growing; a new set of leaves to replace the ones destroyed by scab. His plan v^ould probably fail for at least two reasons. In the first place, the fev; nevj- leaves which he ini^ht induce the tree to gr-ow in late suimnor would be likely to fare no better than the early leaves as far as scab is concerned, because of the chance of infection from the vast number of scabby leaves now on the tree. And secondly, late suranier is no tine to stimulate a tree into vigorous, vogotative growth. But the question indicates a growing conviction among fjruit growers that leaves are important. And that in itself, means real progress in the fruit business, Y/ithout healthy, green leaves until frusts occur in late fall, the tree is not in condition to bear heavy c..;nual crops. By the magic process knovm as photosynthesis a normal leaf takes in COg through its stomates and welds together the carbon viith the hydrogen and oxygen frxi water, to forn starch. This carbohydrate is essential for both vegetative gr^ovrth and fruit development. In fact, none of the vital processes in a tree can proceed unless there is an ample supply of starch available. Starch is required to grow new leaves in early spring and to develop the blossoiAS as v/ell. And as might be expected these spring activities are dependent on the starch manufactured the previous fall. If there v;ere few leaves in September the tree v^ould start Jut in spring under a tremendous handicap as regards its spring activities. But that isn't all. The fruit buds responsible for the crop must of necessity have had access to growth materials, including starch, from the time they wore initiated in mid-summer. One needs only to remove all of the leaves from a tree in July to demonstrate the dependence of the next season's bliss ^ims upon the vital material made in the leaves. The mere diff erentiati'~in of fruit buds is n')t enough. They must be nourished during the late summer and full and provided with st'ired aatorials if they are to develop into blossoms the following spring, TiThat is happening in a tree which is now heavily infected v;ith scab? Its leaves may average less than lO^o efficient, and by September even less, because many have dried up or dropped off. The chrjicos of such a trtjo -6- blocming next spring are very slim. And if it Joes bloora lightly there is no assurance that the blossoms will have what it takes to set fruit. But what of the tree in which scab has been partially c'lntrolled? It is our guess that the set of fruit in 1947 nay be quite closely correlated with the total manufacture of starch between now and late fall. If only a quarter of the leaves are infected, the chances of a full crop in 1947 may be reduced by SSJ^J, Nothing can take the place of large^ green leaves. If their efficiency is lowered by any cause whatsoever, the current season's crop and also the next season's crop will suffer. Those Reddish Yellow Shrubs, Has your attention been recently attracted to an occasional stirub 'along the roadside showing typical autumn foliage? Then you were probably looking at a c'iOkecherry infected with X-disease, a serious disease of peaches. Any such shrubs near a present or prospective peach orchard should be destroyed by applying a v.eGd killer such as Animate* DISTRIBUTION OF I.LASSACHUSETTS APPLES. Any time a half-dozen, or two dozen, apple growers get together talking shop certain quf-tions alvv'ays come up. One is "How many Mcintosh do v;e grow in relation to other varieties?" Another is "Wl^ere do our apples goj chain stores, commission outlets, jobber-hcjidlers?" Still another is "How many are sold direct either to consigners or retailers?" Just to get a little information on some of these points a postcard survey v/as made by asking one hundred growers to cooperate. This group vms selected as a representative crosssection of large ;aid small volume producers* spotted all over the Stcte, including the so-called applo areas and the isolated orchardist; those near l'.)cal markets and th')sc at a distance from consumer areas; in brief, an attempt was made to have the one hundred comprehensively representative of the industry. Fifty-six returned the card. Not all ansv/sred all questions. This group reported total average pr "auction of 700,000 bu,, so they are fairly representative; that's roughly one-third to one-quar'fpir of the State total. How does Mcintosh compare v/ith other varieties? Here it isj 62% Mc's vs. 53% all others combinod. No comment is made except to say that is a lot of Mcintosh, The next most interesting point might be that 37 grov/ers said they sold 13% of their crops direct to consuiners, and 32 growers sold 16^ direct to retailers, C'-'wiparing report cards cuad totaling these tv;o gives a result that these producers dealt directly with consuiaer outlets on 25% of their volume. Possibly this should be expected in a densely populated area such as Massachusetts but the figure is interesting; perhaps surprising. As many apples sold direct, one way or tho other, as were sold on consigiuient to C'snmission houses. The other 7b% went to two outlets; 50^i to jobber-handlers and SSjjJ to coi.oission houses. -7- A must question always in the talk when apple men get together is "How many apples do the 'chains' handle?" Forty-two growers ventured an estimate on this question. These producers were rep :'rting on a totul production of 570,000 bu. of which 65,000 went to "direct" sale outlets. Of the other 505,000 the estimate was &9% to chain outlets and 51^i to independent outlets, To sumr.iarize: 1, Total production 6Z% Mcintosh, Zd% all other varieties* 2. Twenty-five per cent sold direct to consumer or retailer. 3, Fifty per cent sold through jobber-handler; twenty-five per cent through coironissiun outlets. 4. Fifty-one per cent handled by independent stores; forty-nine per cent by "chains," V;. R. cole BLOSSOM THIimiNG SPRAYS. . Some further experiments with blossom thinning sprays were made in 1946 and some suggestive results were obtained despite the frosts, YiTiile the tiiinning by frost probably does nut invalidate :ur measure of the effect of the sprays, the cool weather folliTwing bloom may malce the materials less effective than they would be in a normal season. Three materials were used, Dovifoc seemed to have little or no effect in most cases. Two DN pov;ders were used at -g- and 1 lb. per 100 gallons. They burned the leaves much less than Elge't-^d used two years ago cjid thirjied most varieties quite effectively, Thoy were not effective on Mcintosh and s>.rae similar varieties. A napthalene acetic acid preparation thinned some varieties but caused some distortion of the leaves. Whether this will be injurious remains to be seen, A biennial bearing V/ealthy sprayed last year has a fair crop in this, the normally non-bearing year. These sprays are still in the experiiiiental stage. The effect differs with variety, sorao requiring a stronger c one ont rati -n thfui vthors. It is a promising method of helping out with the laborious job 3f thinning.

If earth surrounds the tree above the bud union, rooting from the scion will surely occur and the dwarfing effect of the stock will be lost. There is going to be a lot of disappointment with dv/arf trees and a good deal of it will arise from the use of improper stocks. It is going to be a big job to keep dwarf stocks true-to-naijie. They can be identified before budding but after the tree gr'Jws it is impossible to be sure in all cases. The Massachusetts Tnjeness-to-name Inspection Service is trying to do what it can to keep the Mailing stocks correct, but it is a diffiotilt task, J. K, Shaw Unveiling a "Eftvarf Tree", A bit of vmrehearsed comedy was enacted in VJorcester last spring. Two business men who live on adjacent properties decided to make a joint purchase of a dwarf apple tree to be planted on the line separating their gardens, y^th due ceremony they dug a large hole, filled it v;ith loam and carried their \vell wrapped bundle to the. scene of action while their v/ives looked on with pride, Yihen the wrappings were removed the prospective orchardists gazed with dismay on — of all things, a Forsythia bushi To make matters worse, one of the men had been trying for two years to rid his property of a tangled growth of that sane kind of plant. Two Observations in a Granville Orchard, In the fall of 1944, 100 apple maggot pupae were placed in the soil beneath a screened cage in the orchard of Ralph Roberts in Granville, Mr, Roberts kept watch of the emergence of files during the sumiaer of 1945. y/hen we visited the orchard a few days ago we decided to take a look at the cage v/hich had remained undisturbed. No pupae had been planted there in the fall of 1945, To our surprise v/e found one maggot fly, which bears out the contention of investigators that an occasional pupa remains in the ground two winters before emerging as a fly. The effect of a good pollenizer on the set of Mcintosh was strikingly illustrated in this same orchard. In one block there are several rows of Mcintosh and a single tree of Delicious. The Mcintosh troes iixaediately adjacent to the Delicious have a very heavy set of apples. On the troes a little farther from the Delicious the set is much lightor and becoracs increasingly so on tha mJre distant trees. Here is an object lesson more convincing than anything we night say about the imp jrtanco of i:iearby pollenizers. -3- That the U. S. normally buys about half of the world supply of bananas? In 1937 v;o imported 63,000,000 bunches and in 1943 only 22,000,000 bunches. It will take some time to restore the banana plantations, shipping, and upset conditions in the big bancjia producing countries. In normal times, bananas are considered the most important fruit in v,forld trade. That approximately one ton of mulberry leaves is consumed in the production of one pound of silk? More than 25,000 cocoons are involved. That fall sot strawberry pl^uits aro unlikely to thriva unless well mulched? Fall planting has one big adv^uitage over late spring planting, in that the roots become established in time to encourage early runner plants the next spring. The principal disadvantage is that the bed must be mulched twice for one crop of berries, and the first mulch must be raked off the following spring to permit the development of runner plrjits. That there has been a seven-fold increase in the canning of citrus fruits in the past nine years? During this period there has been slightly less than a three-fold increase in the t'-ztal citrus crop. Nine years ago a little less than one-third of the grapefruit grown in Florida was processed and nov; two-thirds of the crop goes to the canneries. During the scjne peri.xi, processing of orai:ges has increased from about one-seventieth to one-fourth of the total crop. That about 14,000,000 pounds of load arsenate are used annually to protect tha apple crop in the State of Yfashington? This is approximately one-fifth of the 75,000,000 pounds estimated to be needed for the entire United States, That bagging of quincjs offers excellent possibilities as a means of preventing pest bler.dshes? One Pennsylvania gr:Hver reports using 1000 2-pound grape bags to protect the fruit on tv;o trees. Last year his quinces brought $70^00, One quince v/eighed 16 ounces. That the Oriental fruit moth, is now quite generally distributed over the United States? It is said that every state except North Dakota either has the pest or is bordered by cjijther st^'.te v/hich is infested. That fig trees v;cre first grown in the United States in 1882 when 14,000 cuttings of Smyrna figs v>rere imp-'-rted into California? However, no figs developed and it was not until several years later that investigat .:)rs revealed the secret. Wild figs and a tiny wasp were needed to bring about the pollination of the cultivated fig bl.issoEi, -4- That it takes norc than five timos as nany 2-inch peaches to make a ton as it d'es 3^ inch peaches? One hundred '^f the latter size weigh as much as 535 of the f omor size. That the value of all fruits gnvm in Massachusetts is about :ne~ third the tital fir New England? The percentages for the six states of the approximately ^16,000,000 fruit valuation are as follovi'S: Mass,, 35.5^; Conn., 26.4^; Maine, 2b,l%; Vt., 6.3^; N. H., b,b%; R, I,, Z,Z%* (Crrjaberries are not included in these figures. The Mass, crop in 1945 was valued at 18,460,000.) That the largest source of Nitrogen in the world is the atmos- phere? It is estimated that over every square mile of the earth's surface there are 22,000,000 tons of this element. Nitrogen is known as the growth element in fertilizers. Without fertilizers containing nitrogen and other essential elements, Anerican fanners would have to plant, cultivate, and harvest 50,000,000 additional acres of land to obtain today's food crops. That there was practically no change in the numbers of bearing and non-bearing apple trees in New York State during the five year period, 1940-1945? During the same period there was a 10^^ decline in peach trees and a lO^o increase in cherry trees. That the August estimate of the apple crop in the U» S. is 111,728,000 bushels? This is 64^ more than last year's record low crop and Q% boloiv the 1935 -44 average. That spur blight and anthracnose are limiting factors in many raspberry plantings in Massachusetts? Striking results have been obtained this season in the control of these diseases from applications of fermato after the nevi crjios attain a height of 10 or 12 inches. That four tons per acre is not cm unreasonable yield of grapes in a commercial vineyard? In the vineyards around LrJce Erie the average yield is said to be approximately 1-g- tons, v;hilo individual growers who use commercial fertilizers ajinuaJLy and mc-Jiure every four or five years, harvest 3-|- to 4 tons per acre. Similar yields are reported in other vineyards in the Northeast, That beehives in the orchard should be placed where the sun \vill shine on them raid with entrances toward the east or south? The heat from the sun and the additional sunlight induce the bees to fly and work on the blossoms at times v/hen colonies in the shade will not be active. An Echo of 1916. Imagine a fruit grower ordering 500 Mcintosh apple trees only to find vj-hen they cojuo into bearing that 494 of them v/ere ITolf RiverJ That was the experience of a Massachusetts groover about 30 years ago. Fortu- nately, such gross mixtures are a thing of the past in many nurseries, thanks to the inspection service which has boon in operation since 1921, -5- FRUIT CRACKING Numerous reports have beon received concerning the splitting or cracking of npplos, particularly Early Mcintosh, this season. Other fruits, and even certain kinds of squash show a similar tendency, "^ilfhy is cracking m'lre prevalent this season thpji normally?" The conditi.'in sesras to be assoc- iated vv'ith rainfall. We had plenty of rainfall during May and June, but the first three weeks of July wero very dry. Frriits v/hich had been (-expanding rapidly experienced a slower rate ;^f grovrth in July, until the vory heavy rain which came in the Connecticut Valley on July 23, and was follov/ed by additional rains during late July and August. Yflien the grcvrth of an apple or other fruit is checked, there is a tendency for the cells in the skin to become more or less fixed. They lose their ability to subdivide and thus provide for further expansion. This lack of flexibility means that something must give 7\ray when swelling is resumed in response -tosja additional intaice of v:ater. It's a little like a balloon. Everything is 0. K. so long as tho protective membrane can adjust itself to pressure from within. Arid when the ..lerabraiie gives v/ay, something happens. The splitting of an apple is less violent for obvious reasons, A mere rupture here and there pennits an increase in diameter even though it is literally "hidebound". HIGH HONOR FOR MASSACHUSETTS FRUIT GROYJER A fevY weeks ago John Chandler of Sterling Junction, received the first of what is to be annual awards by the Nati .mal Apple Institute for meritorious service to the industry. At a meeting of the Institute in Washington, Mr, Chandler was presented with a gold watch and a scroll inscribed as follows; "In esteem and appreciati on for distinctive service to the j^ple Industry of America, and to the discharge of his responsibilities in v/artime, John Chandler is presented the National Apple Institute av/ard for 1946," This selection of Mr. Chandler f jr such disti;iguishod honors in in recognition of the fine work v,fhich he did during practically the entire period of v;ar emergencies. During that tine he has been in close touch with affairs in the Nation's Capitol and has travelled extensively thrjughout the country as a representative of the commercial apple industry. Dwarfs and Giants, The necessity for planting dwarf fruit trees in such a way that tho graft or bud union is slightly above the ground level is well illustrated in the garden of an observing grower in Amherst* The base of the trunk on one of his trees was buried with soil dui-ing a.particular season, from May until October, at which time the soil was removed. During those five months a new root 18 inches in length had developed from a point above the union. It is no v/onder that dwarf trees, if planted too deeply, suddenly take on the characteristics of a standard tree. -6- RODENT CONTROL _IN STORAGE AND ORCHARD* (F. B. Schuler of the Fish and Wildlife Service offers thosa timely- suggestions on the prevention of rodent damage.) Fruit growers should be aware of the possible doaage to stored fruit by rats and mice. Every fall there are reports of excessive damage to fruit hold in cormnon and cold storage. On many farms the reported loss is as high as ton bushels for every thousand stored. This loss can be prevented, Coinmon Storage. Conmon Storage is nore open to attack by rodents than fruit held in cold storage, since the former is usually an open building used temporarily for holding the surplus crop. The following recomHondations are made for a rodent-free storage; 1, Remove all trash from the building sind the vicinity of the proposed storage area, 2, Stack usable lumber at least one foot above the ground level, 3, Bum the waste accumulated from this operation. Since rats and mice are Vary animals, the lack of shelter or con- cealment discourages their presence. Therefore, plug with concrete, or shield with galvanized sheet metal or 4 x 4 hardware cloth all openings in foundation walls, floor or embanlanents. Where a rat colony already exists, extermination must take place before harvest. Write to your County Agricultural Agent for information on control methods. When the fruit is harvested it should be stacked at least six inches from the walls, on wooden slate at least two inches above the floor. This will allow for proper ventilation and is also of assistance in controlling the rats and mice. The area along the walls and the free space under the boxes can then be utilized for the distribution of strychnine-treated steam- crushed oats. The oats should be scattered in tablespoonful amounts in theso areas as the storage room is being filled. Bait stations made from mailing tubes, hollow tile, rolled tarpaper or similar devices should be inserted throughout the stacked boxes above ground level, A tablespoonful of the treated grain in each station will be adequate. Cold Storage. The rodent problem in cold storage usually results from the mice being carried into the storage with the fruit. Whenever practicable the fruit should bo moved into the storage the some day it is picked. If allowed to stand in the orchard during the night, mice will use the boxes for shelter and be carried into the storage. Occasionally a cold storage is found that is not mouse proof. Check all drains and vents to be sure they are screened. Hardware cloth with four wires to the inch should be used to mouse proof these openings. In s ;me cases pipe inlets, electrical conduits, offer an indirect mearxs of entrance to the storage. Where they are accessible to the mice they should be checked to see that the exteri ^r of the building is tight. The distribution and placement of strychnine-treated oats should be followed as outlined above. The important thing is to expose the bait while filling the storage. The strychnine-troated steam-crushed oats may be procured through your County Agricultural Agent. Orchard Practices. Fruit trees are girdled in all months of the year. The practice of keeping tree bases free of yegetation is a v/orthwhile precaution- ary measure. Removal of the s )d ar:Jund the tree bases reduces the mouse -7- cover, lessening the chances of girdling during the present grwing season, and also, during the sno\v-free pcri->ds of winter and early spring. The use of this method is highly recommended in young blocks of trees, .ir where the trees are v/idely spaced, with the resulting heavy c iver crop. CAIJNERY GRADES For the first time in history, so far as we can discover, cannery grades of apples are being bought by at least one Massachusetts concern. This provides an outlet for fruit which is not quite good en mgh to be offered on the fresh fruit market. The principal requiremp-nts for these grades are as follows: U» S. ^1 Conners Handpicked apples, 2-g-" and larger, reasonably round, not overripe, froo from decay, wona holes, freezing injury, internal breakdown, and frou any defect which cannot be removed during the usual commercial preparation for use without causing a loss of over 5%, by v/eight, of the apple in excess of that v;hich would occur if the apple were perfect. Color not essential. Light surface scab not harmful, U.S, ^2 Cannsrs Dropped apples and culls from handpicked apples, any size, firm 'rTpo, not overripe, free from decay, freezing injury, excessive internal breakdovm cjid from any defect v/hich comiot be removed during the usual comiuercial preparation for use without causing a loss of over 25%, by weight, of the apple in excess of that which would occur if the apple were perfect. One reason v/hy the first mentioned grade is worth about bO% more than the latter is the larger size which makes it possible to peel, core, and trim with less v/aste. In fact, the lattrr grade apples are used for apple juice. The following table taken from a recent Apple Institute re- lease brings out the relation between size and waste in preparation: 100 lbs, of apples by size 2 1/4" 2 1/2" 2 3/4" 3" Net yield after pooling coring and tri; '.ramg 53 lbs. 66 II 73 11 78 n THE "DROP "CiUEST ION Not so many years ago it was a common practice to begin harvest- ing Mcintosh apples around Sept, 12 to 15, Today we find the harvest in full swing around September 8 to 10 and in some orchards a start is made as early as September 5, The principal reasons for advancing the date of harvest seem to be (1) a desire to get the apples picked before they drop, on the theory that a green, unbruised apple is worth more than a red, bruised one, and (2) a shortage of pickers which necessitates a lengthening the picking season. Both of these points are debatable. In fact, they seem to approach the problem from the wrong angle. In the first place, an excessive premature drop is one of the symptoms of magnesium deficiency. And a shortage of that element can never be supplied by advancing the date of harvest. The Mcintosh variety appears to be very sensitive to deficiencies of certain essential elements. If boron is lacking, internal cork appears. If magnesium is lacking, the fruit drops with alarming suddenness, and under such conditions no response to the hormone, naphthalene acetic acid, may bo expected. Only as the magnesium balance is restored can we produce high colored, high quality Mcintosh. And only then will the hormone be effective in holding the apples on the tree beyond the normal date of harvest* Every observing grower knows that apples size up rapidly during September unless the soil is unusually dry. An apple may gain a quarter of an inch in diajneter during a two weeks period, and that means many extra bushels in a ten acre orchard. Thus if the better colored apples are picked first, the remaining apples will increase in size and become better colored. And even if a few apples drop in the meantime, the drop apples v»ill sell at a fair price while those which remain will gain in value more than enough to offset the bruised condition of the drops, Thea too, if the tree is well mulched, high colored drops will coimaand a better price than green, poor quality apples picked from the tree. The drop question should be considered on a percentage basis. It isn't so much the number of drops under a tree as it is the p-i-rcentage of the whole crop, A bushel of drops under a single tree might seem to be excessive. But if the tree has a crop of 20 bushels, the drops make up only b%, and that's very reasonable. And v;hile some apples have dropped, thjso on the tree have been developing the kind of color oxid flavor upon which the Mcintosh repu- tation is based. If the truth v;ore kn^w/n their added siza might easily off- set the bushel which appears to be lost as drops. ou Any Mcintosh grov/or interested in getting maximum color and quality ght not to overlook the possibilities of using the hormone material as a moans of holding the apples on the tree assuming, of course, that no magnesium deficiency exists. The secret of success in applying the hormone spray or dust seems to depend upon getting it on at just the right tine, covering the tree thoroughly and under the right weather conditions. It requires about 24 hours for the hormone to take effect and, on Mcintosh, the effect tends to wear off in ab mt 8 or 10 days. And since the material is abs >rbed thr:>ugh the stem, a heavy application is needed to make sure that ev-^ry stf3m is cover- ed. The temperature is also iiaportant. Better results are likely to follow an application made around noon of a vmrm day than one made in the mTrning or evening. One of the real values of the preharvest application is in extend- ing the picking season. By treating half of the orchard just before a normal drop occurs, those apples may be harvested a week later than the rest of the orchard and with greatly improved color, size and quality. ■.■•■•■.■•.'

Thies, Extension Horticulturist Contents Soil Conservation in the Nursery jin Observation of plant Nutrition Then and Now in the Fruit Business Simplifying Technical Uatorial Notes on Meadow Mice Control of Odors in Fruit Storages Do You Know? SOIL CONSERVATION THE NITRSERY One of the prerequisites in growing strong and healthy nurserj' stock is a rich and fertile soil which has a plentiful supply of moisture. This point is clearly demonstrated by a nurseryman in northern Alabama. He has been growing all of his nursery stock by the contour system of planting for several years and v/ishes he had adopted the practice before. He is firmly convinced that he is able to grow better trees with this system of planting than under the old conventional square system. At the time wo visited this nursery in late summer it had not rained for several weeks and crops Issued by the Extension Service in furtherance of Acts of May 8 and June 30, 1914, Willard A. Munson, Director, Massachusetts State College, United States Department of Agriculture and County Extension Services cooperating. -2- were beginning to show the effects of insufficient moisture, yet the trees which were planted on the contour were continuing to make new grovrth and showed no signs of lacking v/ater. Soil conservation in this section of the South has taken hold in a big vvay, but it is a case of taking care of the soil or having no soil at all. Some of the finest trees vihichwo sav/ were grovm on land which had been hoavily manured. It is a common practice for many nurserymen, both in the South and the North, to raise beef cattle, not for the beef but pri- marily for the manure which is put on their nursery land. The most vigorous and healthy nursery stock is almost always found in the nurseries which raise boef cattle, A plentiful supply of orgsnic matter appears to be a big factor in growing good nursery stock. If this is what it takes to grow a young tree in the nursery why not give the tree you set in your orchard the same chance it had before it left its happy home? W. D. Weeks AN OBSERVATION OF PLANT NUTRITION In an orchard in Bristol County there is a Mcintosh tree which gives an excellent demonstration of one of the principles of plant physiology that there is no cross transfer of mineral nutrients in a tree. This tree is growing near a fence. Across the fence on a neighbor's property, 15 or 20 feet from the trees, is a pile of poultrj'' manure. On the side of the tree tov/ard the manure pile the leaves were dark green ,tenninal growth was excollont, and the crop v;as good. On the side liway from the manure pile the leaves v.'ere lighter green, terminal growth was shorter, and the crop light. In late August, when this tree v;-as soon, there was no visible evi- dence of any reduction in color on the high nitrogen side of the tree. This observation suggests also that fertilizer applied beyond the spread of the branches may not all be lost because the roots will grew to consider- able distances to obtain the nutrients the tree needs, J. S. Bailey THEN AND NOT IN T^ FRUIT BUSINESS The long time nature of most fruit enterprises suggests a perma- nence not found in certain other enterprises including vegeto.bles or poultry. An apple treo or a grape vino may continue to bear fruit over a period of 100 years. In fact they are so long lived that some gr-jv;ers think of a fruit planting as an unchojiging thing Vifhich may be handed djwn from father -3- to son, Norhing c.^uld be farther fr.>m the truth, A fow ex.aj7iples will illustrate this point. Let us consider first some '-'f the chc'jiges in fruit varieties. In 1914, a firuit authority included the Hubbardston and the Blue Pearmain apples among the varieties v;ell suited to plcjiting in Massachusetts, T-^day these varieties are practically a thing of the past. In 1925, about 25% of -lur commercial apple crop was of the Mcintosh variety ejid about 40^ were Baldv/ins, By 1940, these percentages v;ere just about reversed, T^^day at least 60^o of the commercial crop: is of the Mcintosh variety. The pen- dulum has probably sv/ung far enough, and we now find growers thinking in terms of other varieties instead of planting a still larger percentage of Mcintosh, Of the recoirinended peach varieties 25 years ago, only two remain today, Elberta and J, K. Hale, The Hovmrd 17 strawberry vmich was grown almost exclusively for many years is gradually being replaced by the Cat- skill, These two varieties are about equally prominent today, V/hen the "Nev; Eng^land Seven" list of varieties was prepared in 1928, the Cortland was not included. Today there is no question as to its place in comparison with, for example, the Wealthy and Rhode Island Greenings both of which were included in the 1928 list. In 1916, the above mentioned authority advised every commercial apple grower to provide hiraself with a good barrel sprayer. But the barrel sprayer has given away to the power sprayer v«hich in turn is being constant- ly improved. We have seen a ^vide variety of spray nozzles including the single disc nozzle, spray gun, triplex, quad, spray bro^om, etc. And today many of the larger orchards are equipped with a so-called speed sprayer, Furthemore, most large orchards find it necessary to use both a sprayer and a duster. Things are changing rapidly in the field of pest control equipment. Along with improved equipment, very radical changes are taking place in insecticides and fungicides. The audh" publicized material, DDT, is very effective against codling noth^ Oriental fruit moth, leaf hopper, tarnished plant bug, etc. But it is not a panacea for all insect problems. In 1920, many gr'owors were viondering because of heavy scab in- fections, if we would ever be able to grow Mcintosh apples successfully, (Some have been wondering about the sane thing in 1946), Sulfur in its many forms, including lime sulfur, dry-mix sulfur lime, wettable sulfur, sulfur dust, etc, has been the main stay in preventing scab infections for many years. Today, hov^evor, ferraate, Puratized, and other prjmising materials are beginning to replace sulfur. Now for the first tine we have in fermate a promising control for the rust diseaseas of apples as virell as a means of avoiding so much russetting of Delicious and Baldwin, In Elgetol, we have a material which may be applied on the ground in early spring to reduce the dcjigor of heavy scab infection. Yes, rapid advancement is being made in the control of fruit pests. -4- Other equally revolutionary changes are taking place in orchard soil nanagement. Five years ago, nagnosiun deficiency sy.Tiptoi:is in apple trees were practically unrecognized. The characteristic leaf scorch v/as attributed to spray injury or to dry weather. Today, we recognize this particular type of leaf scorch along with an early dropping of leaves and fruit as due to a shortage of the elenont magnesiur.u Applications of high magnesium line and of niagnesiuin sulfate (Epson salts) in fruit plantings are becoming increasingly comr.ion. The use of the bulldozer and the power shovel in the removal of old, unwanted trees, boulders, stonev/alls ,etc» marks a real step in the direction of more efficient orchard management. Stone walls are being buried, old trees pushed out of the way and the orchard floor smoothed up through the removal of boulders. These practices will reduce production costs and will greatly facilitate the spray program. Contour planting of orchards is becoming more com::ion« A selection of a good soil and a frost free location are assuming much more importance than they did in the past. TiTe are also beginning to appreciate the value of organic matter in the soil cjid the necessity for bringing in additional mulch where trees are planted on lighter soils. Ten years ago it v/as a common practice to place mouse bait in bait stations, bottles or other containers. Today v.'e know that it is much more effective to place the bait directly in the "run", and instead of relying entirely upon strychnine baits we are using zinc phosphide very effectively. The use of napthalene acetic acid to prevent preharvest dropping of Mcintosh has become an established practice. Many growers apply this material in a part of the orchard to extend the picking season. In some cases two appli- cations are made to good advantage, Thore is now in prospect a very effective means of preventing storage scald through the use of solid carbon dioxide. The cause and prevention of storage scald is receiving attention in several experiment stations and control measures are being carefully worked out. Other signs of change in the fruit business include: a trend tov/ard consumer packages and the utilization of low grade fruits in by-products in- stead of placing them on the retail markets High grade apple juice is replac- ing "cider "(with its none too good a reputation). Methods of "firaiing" Mclnjiosh apples for use in pies have been worked out. The forgoing examples by no means exhaust the list of changes in the fi*uit business. They do suggest, however, that the growing and marketing of fruits are undergoing vast changes. Any grower v/ho neglects to read of nev; developments, to observe what is talcing place in other fruit enterprises, and vj-ho is content to do things as they were done in grandfather's day, v;ill find it increasingly difficult to compete in the fruit market. Yv'e are still picking fruit by hand as was done in Grandf o.ther 's day but many other things are being done by novi and improved methods. Still better things are just around the comer. -5- SIMPLIFYING TECHNICAL MATERIAL If technical statei.ients sonet lines appear In Fruit Notes, v;ithout siiaplifico.tion, that policy finds real support in u recent article under the heading "Mania for Siraplicity" by F. L. Thoinsen of the Bureau of Agricultural Econ:>nics, Quoting from the Septenbor 16 issue of USDA: "There are people v;ho hold that everything r.iust be briefed, abstracted, digested, sugar-coated, and so expressed that pictograms and a fev; i.ords of one syllable will tell the entire complex story, Iht^re are even digests of the digests novv, but some stories that should be told, aiid v/ritten, and heard, and read, camiot be ex- pressed in baby talk so that busy people - viho have plenty of time for highly technical discussion of sports or hobbies - cfin absorb and understand pain- lessly. There is a limit to that sort of thing. There seems to be a point at which people should be educated up to understandings and where the effort to simplify should taper off".

Henry, principal Llanmal Control Agent of th^3 Fish and Wildlife Service in Massachusetts,) One of the annual fall probleias which confront the orchardist is that of controlling the meadow mouse. Meadow nice ctaa be controlled success- fully only v/hen the v^fork is done thoroughly, by competent help and under care- ful supervision. Meadow mice arc prolific and under favorable conditions produce several litters of young a year. In favorable "mouse years" there are eight, to ton litters a year, while in years of scarcity, only five to six litters. Litter size fluctuates; large litters predominate when mice are beco:ning abundant. The nu:nber of young in a litter varies fr>Tn one to eleven, the average being five. The mice usually roach soxual maturity when five to six weeks of age, Mead'Ow mice are active through '-ut the year and will damage trees ef all sizes both above and belov/ the gr'jund level, Damago has been noted in evory month of the. year. Mead 3v/ mice do not like to come ">ut in the open. For this reason, keeping a grass free area of tv/elve to eighteen inches around tree base is a worthwhile procedure and off-jrs some protection during periods when no snow is on the groimd. -6- Tho orchard fl:)or is important in nead tw mouse control. The sm )other the orchard floor, the less riajjes, ruts, harrow uarks, holes left by tree renoval, stonewalls and brush rove's, the easier it is to control nice. To deterraine the degree of nouse infestation in your orchard, follOT.' those simple practices, (1) lYhcn mowing late in the surnraer watch for evidence of mice, (2) THiile gathering windfall apples note areas in the orchard where most apples are nibbled.

Inf orr.iation on hovif to procure these baits can be obtained from your County Agents, Fresh apple cubes one half inch or larger treated with zinc phosphide placed in active runways in^Aediately after windfalls are picked up will give excellent results when thoroughly and properly applied. One such treatment yearly should be sufficient. Stonewalls, brush rows, stone drains should be re-treated before snow falls. The broadcasting of poison baits is not recommended, not only because of the poor results obtained in the control of mice but also, because of the danger to other wild life, Tifhile mouse- signs in the orchards this year may not be as easily seen as last year, no grov/er should omit this work from his orchard program or permit it to be done haphazardly, A job worth doing is worth doing well. CONTROL OF ODORS DJ FRUIT ST0R.;GES (The following suggestions from Dr. Smock of Cornell University are particularly timely at this season when apples are being stored in all sorts of storages, good, bad and indifferent.) Stored fruits absorb odors very readily. Apples have been dis- counted in price in late spring because they had absorbed foul odors in st "^rage. Those absorbed .odors do not leave the apples very readily even after they have been removed fr^vm storage. For example, one lot of applesauce had to be destroyed because the apples used in its manufacture had been stored v/ith potatoes. There are many sources of foul odors which may c -:»ntaninate fruit in storage. Sometimes building materials are the source of odors, Occasi 'n- ally other f'^'^ds stored with the fruit are the source of trouble. Potatoes -7- cabbage, or onions are p':itcntial ^^dor producing materials that may cause off flavor in applos when stored together. Soinetimes surface molds grov/ing in the storage produce strong musty odors which are absorbed by fruit. Only odor free material should be used in the construction of fruit stora^'is. Certain of the odors emanating from construction materials can be romcved by proper air purification methods, but adds more expense to storage. Although surface molds can be controlled by keeping the relative humidity in storages belo;v 80^, it hardly constitutes a ^ood method of control because the apples ^/vill shrivel during extended storage at such a l'3w humidity. The control of surface molds at high humidities is possible by the use of ozone. Because of the expense and the unreliability of ozone generators, hov;evor, control of molds with ozone has not been very widely adopted. Store Crops Separately. For best results, apples should not be stored with other foods which have a strong odor. In addition to having different storage requireraents than the apple, the odors from these foods may be taken up by the apples, Yi[hen im odor problem does exist it con often be eliminated by air purification. Many odors can be successfully removed from the storage by passing the air through beds of activated charcoal, made from coconut shells. While this method of control is relatively nevr it has been demon- strated to have considerable merit in several tests. Success with this technique involves goodcir circulation throughout the whole storage chamber so that the atmosphere of the entire room is purified. To be perfectly safe, apples should be stored alone in clean, odor free storages at the recommended temperature and humidity. This is the cheapest end most certain means of assuring satisfactory quality when the fruit is removed from storage for sale. Supports for Grape Vines. Grape growers interested in ' a source of cedar posts or stakes for making trellises may obtain some information by contacting the writer. A large supply "in varying lengths and sizes at attractive prices" is said to be available. Only 6 Sprays. A Middlesex County grower has succeed- ed in bringing through a very creditable crop of Mcintosh this season and has applied only six sprays. A lettable sulfur was used four times and lime sulfur twice, plus lead arsenate and lime in all but one, the blossom spray. "No Pincha da Peach'.' To satisfy public curiosity, someone has suggested displaying a coconut on a fruitstand with this placard, - "No pincha da peach; pincha da coke". Not a bad idea. Ir That the date palm is one of more than 1200 species of palms cuid at present is the only species under commercial cul- tivation? For more than 4000 years tho date has been a valuable food for people in the valleys of the Tigris and Euphrates Rivers in southera Asia. To the ancient Egyptians, the date palm was a sign of the Dresence of v/ater. That some excellent sUj-.gestions on storage construction are pi'esented in the September issue of tho Ai"iierican Fruit Grower? It contains throe storage c.rticlss, - "Remodeling Old Buildings for Cold Storage Units", "If You plan to Build a Cold Storage", end "Rat Control in Cold Storage", That information on DDT Residue Tolerance has been published in a recent bulletin by tho National Apple Institute? Investigations of several cases of humcai illness attributed to DDT have eha.-jn the original diagnosis to bo erroneous. That there are as mtmy as 11 generations of some species of aphids in a single seasoni Many species produce from 50 to lOO yjung per generation. On the basis of 10 survivors per generation, one aphid could have 1000 decend- ants by the 4th generation. No wonder they seem to take possession of a plant while one's back is turned. That "goop", a magnesium dust nixed v;ith asphalt ^uid tar which was used in incendiary bombs in wartime, may prove useful in the orchard? At Michigan State College it kept piles of orchard brush burning briskly. Goop has a consistency like clay and may find a place in orchard heating. That orchard reorganization is one of the most pressing needs on most fruit farms? Relieving cr-ivvded conditions, introducing pollinizers, catching up on long delayed pruning, getting rid of stones fjid planting a new block to replace an old ona are somo of the items which deserve something more than vashful thinking. That the so-called Milky Disease offers promise in the control of Japanese Beetle? The disease inv-.)lvys a spore f^'rming bacterium tind the normal invasion route is via the alimentary canal of the host. Both the vegetative and the spore forms seem to be infective. Grubs acquire the disease by in- gesting spores along vdth their food. Disintegration of diseased grubs, after death, liberates spores in the soil. The number of sp.ires produced per grub approximates 2,000,000,000. That color and quality of apples are likely to be poorer vmero the loaves are heavily infested v;ith rod mite? Qu )ting from Storrs Horticultural Notes, "Tho bright, dry weather of late_ August end September has favored an unusually heavy red mite build-up. Mcintosh, Delicious roid Baldwin are most seri 'Usly affected. If bronzed n Jticoably by mite at prssjnt, apples may drop excessively and early v;ith poorer color. Also, hormone materials applied to bronzed foliage crnnot be expected to be as effective as applied on clean, green leaves". - Q Vu.^-^:::^>>>c^s^^.:jfe:^V<^^^ ■■^^^;^?i^v^>a ^^^^^^^^^ iili^i .<»s^::<^^v';^:y:^^•:%j:^^»;^;V^ -^^^^^ ■ ^#s«f fc'.ll planted trees, W.

To one who has v/atched the apple business for more than 40 years it appears th.->.t this country has, in general, produced about as mraiy apples as could be sold at a profit. In some yoars the crop has boon sh ^rt cjid the price high; in other years more have been grown thrji the market could well absorb PXid prices have been 1ot,v, The number of trees has tended to decrease but tree yields have increased. This seems to indicate that no material increase of orchard trees is v;arrraited. Yet trees grow old and unprofitable rjid must be replaced if production is to be maintained. This is particularly true in Massachusetts, Most of our :>rchards are more thr'Ji 20 years old cxid at ab 'ut 40 yoars trees are likely to pass into the un- profitable stage. This suggests that more trees eiust be ploiited within the next few years if profitable production is to bo maintained. If we expand production here it must be at the e:.pense 'if othor* apple regions. Our best growers can compote with ^xny othors but less skillful rjid loss lucky ones are at a disadvantage. The last three years have emphasized the importance of sites with good air drainage caid v/e know something of the import-once of good soils. It is and always will be foolish to plant orchards on poor sites and soils. The importance of a well organized, efficient orchard orgrjiization is not fully understood. Some gr'3wers can expraid their business without a proportionate increase in -unit cost ruid thus obtain more profit. Perhaps most growers should plant with the expectation of removing an equal nujiier of old trees as the neviT trees como into production. The IJcIntosh is ,and, until a better variety appears, vifill continue to be our most importtuit variety. But vre need other varieties for polli- -2- nation and to extend the harvesting and marketing season. V^at varieties shall v/e pl-mt? No definite answer can be given, Cortlaiid is second in importance; the Baldwin is apparently going out. One of the nost proinising replacements is the canparatively new variety, Davey (Dc~venport 25), It is equal to BalcTJin in all respects except that it Vv'ilts unless stored in rather high humidity. The tree is iiardior, more productive and crops at an earlier age, VHisthor it will do well u:,ior a v.ide rjinge of conditions is not yot knov.ii. If trees were available it v;ould be v/orth cji extended trial. Golden Delicious should overccsme the projudice against yellow r.pples but our season is a little tOD sh >rt and cool to alle-.v best development, md an imm;'.ture Golden Delicious is 'practically worthless. It should be planted only v/here early maturity may be expected, Rome Beauty nov/ interests some grOT/ers, It is a cheap apple. It soils at a ratlicr l.r:f price but it can be growr., at a lovi'sr cost. As with other vc-rioties, one of the red forms such as Gallia is probably better thcji the true R?me, The red sp'jrts, v/hon available, are steadily replacing the old, less well colored varieties. Varieties earlier than Liclntosh should be planted only in small proportion, Vfhen iiclntosh com'js into mr.rkot, earlier varieties are at a disadvantage, V/e may soaa have too many Early Mcintosh, To sui.'^ up - no great expansion of the apple business is v/arranted but our 3lder orchards must be replaced if production is to be maintained. Only the best sites and soils should be used; only the most profitable varieties sh'uld be planted and by the best grov;ers. The apple business requires gr^i.t knoivledge and skill and the begir^ier should proceed cautiously, J, K.

H, Palmiter of the Geneva, Nev/ Y:^rk Agricultural Experiment Station the use of certain materials on the orchard flo ;r is summarized as follows: "Apple scab control experiments indicate that the canount of primary incjulum (spores '^f Venturia inaequalis in over-wintered apple leaves) in a yuar favorable for disease development may de- termine the success or failure of the scab control program. Orchards in which loss than 5 per cent of the old leaves contained spores '..t,ro v/oll protected from apple scab infection with from five to seven applications of Vi'e"jtable sul- fur. Similar orchard's with more abundant inoculum required extra fungicidal applications and higher concentrations of sulfur for equal disease contrwl.Nine -4- yoars of laboratory tests and field experiments showed the effectiveness of certain chemicals in killing or preventing the discharge of ascOBpores of the scab fungus* "Nitrogen fertilizers, such as nitrate of soda tmd sulfate of oinnonia used at 12 per cent concentration, were effective, but the 500 to 600 pounds required per acre for effective coverage increased the nitrogen supply available to the trees beyond the optimum amount for best fruit quality, "Elgetol used at 2 quarts to 100 gallons reduced the primary inoculum more than 95 per cent when carefully applied and resulted in improved scab control. The ground treatments v:ere most effective in years of excessive rain- fall, like 1943 acd 1945, and reduced the anwunt of fruit infection on trees receiving a vottublo sulfur program from 20 per cent to 2 per cent." As a concluding statement Dr« Pal:nitcr says "No foliage fungicide sprays should bo omitted because of the ground application. It is an extra application to give extra protection in scabby orchards," (The above publication is Bulletin No, 714,) DEVELOPMENT OF ORGAI^IIC FUNGICIDES, In order t^ understand present day developnients in plrnt post control, J. G, Horsfall of the Connecticut Agricultural Experiment Station says, "The farmer must brush up on his chemistry." In a recent issue of the AIF News he gives us a little insight into the procedure involved in discovering and testing jrganic fiHigicidos, Foll'ov^ing is a quotation from his article; "The first step in developing a new fungicide is the *Edisonirji approach; try every- thing once,* We at Connecticut have tested some 6000 oompounds that way. It is slow. It is laborious. It is not very productive, "Having discovered a fev;^ possibilities, one then examines their chemical structure. Referring to his college chemistry, he vdll remember that every chemical is built up if parts v.'hich fit together in a certain v;ay. The chemist can draw a picture of a chemical. This is called a structural formula. If thej^ sec that the structural formula for a nevf compound resembles that for a known fungicide, they can be fairly certain that the new compound will also be a fungicide, "Automobiles are built of wood, iron, copper and some other things. So are houses and factories,. An aut'Snobile is a car because these ingredients are put together in a certain fashion; a house differs chiefly in that the materials are put together differently. Hence a fiingicide differs from a foodstuff mostly because the ingredients are tied together differently, and each can bo recognized because of that fact, "in our laboratories wo pass a novr chemical through a series of screening tests.

The results cf this survey, published in Bulletin No, 35 of the National Apple Institute are so timely that they are reprinted here for the readers of Fruit I-Iotos, They suggest one reason why the o.insumption of apples fell from 44 pounds per capita in 1920 to 32 pounds per capita in 1940.

Br.ldvdn apples in many orchards sh-'wed inferior c ^l/^r this full even though harvest was delayed until October 15 or later. This lack of c 5lor nay be related tc oji unusually mild nonth if Oct ")bcr. H'jre's one theory, for v/hat it nay be v.orth. In most seasons a hoavy frost occurs bef '.'re the first oC Oct /ber. This tends to check leaf activity and set the stage for the development of color in v.-iutor varietitjs. During the current season only light frjsts occured in m^iy areas evon as late r.s mid - October, i-nd the loaves continued t^'.' manufactii.ro st.:.rch. As this is being v/ritten (October 30) the weather is still s ) warm that ripples hanging on trees may still be increasing in size and certain other grjvrth processes may bo c^mtinuing on a moderate scale. A rank gr'ovrth of now grass in recent v;eeks is further evidence that Nature is taking advtuitago of the springlike weaxher in ono last vegetative fling. Our theory, -chen, is briefly this - A supply of the material (glu- cocide), frjm v/hich the red color pigirisnt is made, failed to materialize because the starch Viias continually being used elsev/here. And so the Baldv.dn apples remained more or less green. A heavy frost might have done two things; (1) Induce the tree to terminate its sur.imer activities, emd (2) Bring on the clear atm.esjhore which favors the transmission of ultravi )let light, a vor^ effective aid in the coloring process. But Baldvidns in some orchards m.aj/ have failed to color for another reason, - red mite. The leaves v/ero actually so bronzed as to be very in- efficient in starch ratxiuf acture. Very poor loaves mean very limited starch supplies, slow m£\turity -^f the fruit and retarded color development. There is reason to believe that red mite tends to build up more rapidly where DDT is used sines it kills off some of the natural enemies of the red mite. TREATMENT OF PRUNING- ".VOUI.DS. Much valuable time is wasted in pninting pruning v/ounds. In fact some amateurs seem to place more emphasis on painting than they do en cutting off the proper limbs. In a vigorous tree, any correctly made cut up to 1-^ or 2 inches in dicmeter tends to heal conplotely before doc;.y sets in whether treated or not. Larger cuts, particularly on winter injured trees, should perhaps be treated. Decay in older trees is t^dcen for granted and, if we assume that a 40-year-old apple tree has reached the replacement sta^e, we are naturally less interested in pi'cserving it intact as we might a valued antique, iilain- tenanco of a strong frainewcrk thr..ughout the useful lifetime of the tree and protection of the foliage are luore important tht'ji the mere treatment '">f pruning wounds. For v/ithout these two essentials vio are attempting to patch up a decrepit shell instead of focusin.g our attention on things that count. In Comoll Bulletin 821, by Vi'clch end MacDaniels, the essentials of a good wound dressing are stated as follows: "Vfood decay greatly limits the life and usefulnesG of orchard trees. Decay in older trees is univer- Bally t!j:CQii fur granted, ar.d thiiiB'it ofton happonft that t-jo littio attention is paid to tho possibility :>f proTonting jr at least postponing tho otart of •'.ocay.

Causes of wounds are numerous, rjid m.>st of ther.1 iiTo ftu:iilitu:. In the orchard, pruning operations cause the most wounds, f'nd although these are intent i^^nal, thoy nevertheless ondaiigor the tree. Protective treatment of such wounds is thus in,M3rtant, "The object in treatiuient is to protect the exposed wjot' fron fungi and insects, yet to interfere as little as possible vvith the namal healing process, Uany r.iatorials have been prop^jsed as wound dressing for trees, but no one substance has yet proved to be entirely satisfactory. The reasons why tested Materials ha\'e been found faulty becoue obvious when 'the sssei:itial reauirei.ients for a g^-'-d wound dressing are considered. Briefly such a material must be: (1) Durable under all conditions of exposure, Maintaining a per- mc-xient toid continuous surface which will prevent chocking and cracking of the wood* (2) N^t seriously injurious to freshly exposed living tissues of bark, canbiuia, and sapwood, (3) Ii.apor-uotible, repellent, or toxic to fungi, insects, and other hamful organisns or agents, (4) Inexpensive and readily obtainable, (5) Easy and convenient to store, handle, and apply, (6) In- conspicu .5us, (applies particul-.'.rly to shade trees)," After testing 24 materials including white house paint, Bordeaux paint, c 'ppor resin, and variations of asphalt water emulsions, asphalt paints, orange shellac, blue Vifagon paint, coaltar pain-6, red bam paint, and water- glass, the authors dravi this conclusion; "Tho results of these studies do not point to any one material as being entirely suitable for treating pruning wounds on trees, Fr-or.i the standpoint of durability coid froedom from injury to -che cambium, tisphalt-water emulsion, white house paint, fibrated asphalt paint, Bordeaux paint, and copper resin have considerable prOLiise.** More Freezer Lockers, More than 8000 freezer locker pltmts are now in operation in ^he U.

For the axperienced gr'^Vi'er, however, who is able to supple- ment the chart with his awn experiences, the new set-up may be a real im- provement. In this issue of Fruit Notes v;e present the Notes having to do with Insecticides, In the next issue, the Notes on Fungicides will be presented. The printed chart should be ready for distribution by mid-wintor. Insecticides (Dormant and Delayed Dormant Sprays) The choice of insecticide depends on the pests to be controlled, Dinitro compounds are most effective against Bud Moth, Rosy jiphis, and the eggs of other apple plant lice. Oil emulsion or miscible oil is desirable to combat Red Mite and San Jose Scale, If one or more pests of each .group are present, a combination of oil and dinitro is recommended, Dinitro compounds (dormant) as prepared for dorniant spraying must be applied v/hen the trees are strictly dormant to avoid injury to the buds. They should be used according to the manufacturers' recommendations. They are available as (1) a liquid to be diluted in water (Elgatol and Krenite)j (2) a powder to add to water or to an oil emulsion (Dow DN dry wettable), and (3) a combination of DN in oil (Nitrokleenup Dow Spray Donnant), Y/hen a DN-oil combination is prepared in the tank, it is desirable to reduce DN to one-half or two-thirds the amount required when used alone, Miscible oil or oil emulsion as prepared and recommended by established manufacturers is generally satisfactory. Paste type oil emulsions are frequently preferred. For control of Red Mite Z% actual oil, and for the San Jose Scale 2% actual oil, in the diluted spray is advised. If an 83^ Oil is used, 3 5/8 gallons in 100 are required for a 3% actual oil dilution, while 2 1/2 gallons result in 2% actual oil. If a 75% Oil is used, the amounts for corresponding dilutions are 4 gallons and 2 3/4 gallons, respective- ly. Oil sprays should not be applied v/hen there is danger of continued freezing weather before the spray dries. Insecticides (Summer Sprays) Lead arsenate (standard or acid form) is the most commonly used stomach poison during the growing season. It is compatible with the other insecticides listed and vjith most fungicides. The preferred dosages in 100 gallons are; Pre-blossom sprays - 3 pounds; Calyx, 1st and 2nd Cover - 4 pounds j 3rd Cover - 3 pounds; 4th Cover - 2 pounds. In the 1st Cover period when young fruit is growing rapidly, spreading and sticking is greatly increased by adding 1 pint of fish oil or rav/ linseed oil as follows; In a separate container v^et the lead arsenate to a thick paste, add the oil slowly, and stir to consistency of paint; dilute with water and pour into tank. In the 2nd Cover, when the first generation of the Codling Moth is most active, DDT can be substituted for lead arsenate effectively. In the 4th Cover, DDT or a combination of DDT (50^) 2 pounds and lead arsenate 2 pounds is desirable on varieties later than Mcintosh to protect against late Codling Moth, Leaf Roller and Bud Moth as well as Apple Maggot flies. -3- 4:0% Nicotine sulfate is very effective for combating Apple Red Bug and Apple j^hids. One pint in 100 gallons (1-800) is usually sufficient, and it is compatible v/ith all other recomnended materials, Vs'hen used alone, nicotine sulfate should be fortified with 2 to 4 pounds of dissolved soap or soap flakes but in combination with other insecticides or fungicides the soap is unnecessary and may be harmful. For combating Leafhopper, DDT may be substituted for nicotine. DDT is both a stomach poison and a contact insecticide which retains a toxic residue for 10 to 20 days. The preferred form for orchard use is wettable powder containing 20% to 50/b DDT (most brands are novf 60%)» Less is known about the effectiveness and compatibility of the emulsible < concentrate. The standard formula is 2 pounds bO% wettable powder or 4 pounds 25jb wettable powder (both equal 1 pound actual DDT). DDT is recommended in: 2nd Cover - to control Codling Moth (first brood,)' and in tho 4th Cover - to cintrol Codling ^Moth and Leafhopper (both second brood) especially on varieties harvested later than ilclntosh. Experiments indicate that 2 pounds bOfo DDT and 2 pounds lead arsenate are more effective than 4 pounds lead arsenate in all post blossom sprays, and the combination is suggested where .any of the insect pests are abnormally abundant, DDT is compatible with all materials except lime. It should not be used in pre-blossora applications because of possible harmful effect on pollinating insects. Dinitro compounds (summsr) such as Di'J-111, used at the rate of 3/4 to 1 pound or as advised by the manufacturer, is effective for summer Red Mite control. Dusts such as DI\rD4, are also effective. Both sprays and dusts are compa"cible with lead arsenate, DDT, wettable sulfur, and Fermate and may be used safely after the 1st Cover when temperature is belov; gO'"^ F., or below 80° F. if combined with sulfur. For prevention, this material may be added to the 2nd Cover spray or it may be applied separately v;hen a Red Mite infestation threatens.

He is interested in long range develop- ments and is accustomed to planning for the years ahead. In 1920, the Massa- chusetts Fruit Groviers ' Association set up a so-called Ten Year Program which embodied the objectives of the industry as viewed by the leaders at that time. In 1931, the Ten Year Program was revised, and now after a war-time delay of several years, a committee is at work making a second revision. Since the full committee of the M, P'. G, A« has not yet completed its recommendations, this report is a preliminary one looking forv/ard to 1957. Future Plantings. Soils and sites must be carefully considered in all new plantings and in the extension of present plantings. The past tv;o years have emphasized the fundamental importance of a good orchard location. Varieties. The list of commercial apple varieties knovm as the New England Seven, foitnulated in 1928, needs to be evaluated in accordance with present day conditions. The i'.IcIntosh still heads the list although future plantings will be made \vith more attention to suitable pollenizers including Cortland, Delicious, and a few others. The Cortland is of more im- portance today than it v/as a decade ago and now deserves a place in our comjnercial list. Northern Spy and Baldxvin will be planted sparingly. V/ealthy, Gravenstein, and Riiode Island Greening are in r.iuch the same class. Early Mcintosh and Gallia have gained in favor and may como into somewhat greater prominence. Diversification. More attention must be given among apple growers to the production of other fruits, such as peaches, pears, small fruits, and in some cases to vcf^etables. Livestock and poultry are apparently less well adapted to the specialized fruit farm. V/here these enterprises are included in the farm program the special requirements of each as regards land, seasonal labor, and equipment must be borne in mind. Pest Control. The Committee recommends continued testing of new and promising spray and dust materials. Experiir.cnt Station tests of DDT, Fennate, etc., together v^ith the experiences of grov/ors will bring about more effective fruit post control. The next ten years are likely to see radical changes in spray materials, spraying and dusting equipment, and in methods of application. Soil Management. In the past five years rapid strides have been made in correcting a serious deficisncy of magnesium in Massachusetts orchards. The use of high magnesium lime, magnesium sulfate, etc. marks a great advtmce in the fruit industry. Our soils are, on the average, low in available mag- nesium. The replenisliment of this element in the soil must be placed on the same basis as nitrogen, v;hich most grov/ers apply annually. The so-called complete fertilizers do not take into account this essential mineral clomont. The use of magnesium and boron, and of mulching materials must receive continued -5- emphasis during the next ten years. Orchard Reorganization. The Coranittee rocanmends a thorough reor- ganization of all present day orchards, Many of our orchards are below par for one or r.iore of the follc.ving reasons; (1) trees crov/ded, (2) too many obstructions such as stone walls, boulders, brush, etc,, (3) lack of pollen- izers, (4) poorly drained areas, (5) inconvenient water supply for spraying, (6) too many old troes, and (7) need of extension by planting a new block on a good soil and a frost free site. These factors nust be stressed during the next ten years. Our fruit industry v;ill be on a firner basis in 1957 if growers reorganize all present plantings. Marketing, Rough handling of fruits probably detracts as much from their sales value as insect ai^-d disease bleiTiishes, A method must be v.'orked out to place the Mcintosh apple in the hands of the consvuner in bettor con- dition. This means more careful handling and a better container. The problen should be attacked from several angles; (1) handling more carefully on the farm while the fruit is still x^nder the grov/er's control, (2) eliminating un- necessary marketing machinery, (3) development of containers to protect the product all the way from the tree to the consumer. In conclusion, the Ten Year Program Coinmittce looks forv;ard to 1957 with optimism. As we tackle the problems enumerated above, taking advantage of neiv developments, and pooling the experiences of all concerned, we shall find ourselves in an increasingly good competitive position and we shall be able to deliver to the ctjnsumer a fancy product at a fair price, D* V/'.

By scheduling the School during the Spring Vacation, we shall have facilities not available while classes are in session. Staff members for ex- ample will not be tied up with class v;ork, LEI^^GTHEiaNG THE SHELF LIFE OF FRUITS AI-JD VEGETASLES In a recent issue of DuPont Agricultural C'Omment, Dr, C, Vf. Hauck, of Ohio State University presents these interesting facts concerning perish- able products: "'Shelf Life' is a term vmich may be foreign to many fruit aiid -vegetable growers. To the retailer of these commodities, hovj-ever, it spells profit or loss. In the parlance of retailers, 'Shelf Life' is the period of time during v;hich the produce received by the retailer remains fresh, attractive and appealing to the customer. Enough so that the retailer is not forced to reduce the price in order to move the product. Fruits jurid Vegetables Are Alive, Although we seldom consider tliem as such, fresh fruits and vogotablcs are living, respiring parts of plants. They must be cared for and handled as such for they are materially affected by conditions to which they are subjected. The life of apples, peaches, tomatoes, cabbage, or the like is shortened by any factor which has a tendency to speed up the -6- noTOial riponing or aging process, or any factor which permits dehydration, decay, physical damage or other deterioration. In contrast with this, the life of fruits and vegetables is prolonged by favorable temperatures and humidity, gentle, careful handling, protection from insects and diseases and other protective measures. It is true that 'Shelf Life' is a factor v/hich is the major concern of produce retailers. On the other hand, grovvers cannot afford to take an indifferent attitude toward this problem. Directly or indirectly it definitely affects their v/elfare. Produce which does not keep v/ell on the shelf and does not attract the eye of the consumer is produce which may not command a return order. In order to avoid excessive losses, a retailer may offer only limited quantities of produce in an effort to keep them moving ovor his counter. This in turn will result in limiting sales outlets of producers. The grower of fruits and vegetables may determine 'shelf life' as early as the plants are set in the field or before the first buds appear on the tree. Herein the pro- ducer becomes responsible for the use of tested and proven varieties, and for the control of insects and diseases which may ultimately affect the 'shelf life' of this produce months later. Not all the responsibility for the 'shelf life' of fruits and vege- tables can be laid at the feet of the producer. It must be realized, however, that this is the beginning point and that fruit or vegetables do not improve in quality after thoy leave the vine or tree. In other words, the quality must be in the produce when it is harvested. It is true that conditions in produce handling by v.'holosalers and others, among the line to the retailers may greatly reduce the 'shelf life' of produce, but thoy can never improve the quality. In the not too distajit future the quality of produce on the dealers' shelves will again become the major factor in determining the acceptance of that product by the consumer. As a result, it behooves every producer who is anxious to continue to produce for a discerning public, to make available from his orchards, fields or gardens the best fruits and vegetables v/hich agri- cultural science and mechanical developments are able to produce. Factors of weather, moisture, soils and the like present sufficient problems in the growing of quality produce, so that no grower can afford to overlook the opportunities of favorably affecting all other factors which are vi'ithin his control. In the long run tliere is no substitute for quality," FRUIT GROVvING JN POLAIvT) Dr. Stephen pieniazek, formerly a member of the R. I. State College staff and now in charge of work in Pomology in a University at Skiernievdce, Poland, writes as follov/s on conditions in that country: "The fruit grov/ing situation in Poland is this. The orchards are few and not taken care of properly. Spraying v;as abondoned in many instaiices during the war because of wearing out of the old equipment vdiile no new machinery was manufactured. -7- No power sprayers wore ever used in Polaiid. This is true also for most of Gorman orchards. Knapsack and barrel sprayers v/ore the most common. They give satisfactory results in vi*jw of the fact that our posts arc not as bad as yours, I have soon orchards \/herG no spraying was done producing a fair fruit, ¥;'e have some good orchards and some very different from yours. There is a two hundred acre orchard in Csiny near Skicrniewice comp.)sed of dwarf and semi-dwarf apple trees. The dwarfs arc treated here as you would treat tomatoes. They are plaiited as close as 6 x 3 feet and boar fruit next year after planting. This is the system of the so called "intensive orchard* ing". The apple trees are not the only crop gro'/m on the soil. At least two successive crops of vegetables are grown betwe .;n the trees each year, early cabbage and snap beans for instance. Heavy fertilization and continuous cultivation enables the soil to give heavj- ^/iolds. Our standard orchards are never grown in sod. It is claimed that our climate is too dry for this system (20 inches rainfall). The soil is cultivated in the spring and c jvyr crops are suvm for the late sumner and fall in mature orchards. Vegetables, p^/catoos and similar crops are grovm in young orchards, l/Ye have a plcjit as a cover crop iicre that, I think, far exceeds most covsr crops I have seen growing in the United States, This is lupine. It mokes a very quick growth and gives a large volume of green material. It will stand dry weather very well and will grow on very poor soil. As a legume it is especially desirable. It is much hardier than soy beans and is killed by a rathor heavy frost. It's stems are thick and sturdy vAich mries it very good plant for retaining a great deal of snow in wintor. As I understand it lupine v;as recently introduced in Florida cjid other Southern States v.'hcre it xjas enthusiastically received, I think it would grow even better in the North and would give better results as cover crops in peach orchards than the plants you grow there at present. You could get seed for trial from Florida. If you want it I would be very glad to send you some of our seed if AiTiericon quarantine laws will permit its entry, \'{e would arrange here for the inspection of seed to be sent to j'-ou. We have started work on reconstruction of our fruit grov/ing hero and I am in charge of planning experimental work in pomology. We are ready to plant large experimental orchards in the spring. The necessary lands and funds have already beon granted by the governiaent. On our College land there will be a new experimental orchard of ov-,r a hundred acres planted in the spring. The v/ork on soil noi-iagement and fertilization, aianual bearing, winter resistance tuid so on will be done h'^re, I vjill have -jne block here of 25 acres just for soil management studies," -8- PRUNING BEARING TREES One side of the pruning problem is often overlooked. It takes relatively few vigorous, v;ell placed branches to produce a full crop of high quality fruit. If the ideal distribution of good branches on an acre of orchard can be obtained with half as many trees, that is a real advantage because the extra trees mean an added drain on soil fertility and moisture, to say nothing of their shading effect on the other trees. Fruiting brariches must have good exposure to light. The individual trees must therefore be vvell spaced. Ground level pruning of half of the trees means economy in spraying, fertilizing, thinning and later pruning. Instead of thinking en- tirely in terms of pruning the individual tree, we ought to consider the job on an acre basis, A number of vrell placed branches on a few trees is better than a fev/ such branches on many trees. The majority cf bearing orchards in Massachusetts include too many"boardor" trees. The bulldozer is an ideal tool for eliminating these unwanted trees, V/hen they are out of the way the remaining trees present much less of a problem. Drooping, shaded, submerged, and other^vise handicapped branches and parts of branches should be removed. Each remaining branch deserves a "place in the sun". The branches v;e retain are much more important than the ones we cut off. 1946 INDEX (First number indicates t Apple By-Products 8/7 Apple Maggot 8/2 le month; second, the page.)
