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 County 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 volume. 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., Ser)t., Oct.); 1939 (Oct.); 19A3 (Aug.); 1946 (Feb., Nov.,);1947 (Jan., Ma-js June, Sept.,); 1943 (Jan., Mar., May, Sept.,); 1949 (Jan., :SSS^, June, Sept, Dec.,). ■.si r .

B. Burrell of Cornell University. The effect of drouth, however, is an indirect one, probably opcratin-^ throu[;h a reduction in the absorption of boron. \Je are indebted to Dr. Burroll for the follouin™ recommendations. Insurance against a reciu're::ce of internal cork is bobt obtained through application of boreix to the soil in a ring beneath the tips of the branches. The fine granular fori", is best suited to the purpose, being lowest in jrrice, easily spread, a:id not so subject to for;.j.ng hard lunps as the pov/der forn. Application of straight bora;: v;ithout dilution is preferable to i-dxing it with other ;uaterials, or depending on the boron in fertilizer r.iixtures. It is custonary to irake cor.nnercial app:lications at the sa.uG tiue as nitrogen fertilizers are put on, i.e., around tlie ti;.ie of the delayed dorasirc or early pre-pink sprays. Provided the i.iaterial is ¥/ashed into -the soil a fe\-f v/eeks before the appearance of synptorjs, aiiy date during the grov/- irig season seei":s satisfactory. Application of bora:c to trees whose fruits showed sone external cork on June 30, 1S39, greatly reduced the developi.ient of internal cork during the bala-ice of the sur.X;:er. On the untreated trees in this e::peri;?.ent, late-season internal cork was severe. Late fall asid v/inter are considered undesirable -'c±::es for applying bora;: sending furth-er study.

But several of the uorthj^ old tiners are still r.dssine.

Several of these varieties were forri.erly included in our planting but the hurricane has reduced the nunber considerably. These varieties are anonr; the riissing; Auturin Strawberry, Bailey Sweet, Bottle Greening, fethead, Congress, Dudley, Fall Harvey, Fall Jennetting, Gideon, Golden Pippin, Hightop Sv/eet , Holden, Jacob Sweet, Lyscor.: (l.]g.tthev/s' Stripe), i.'inister, IJodhead (Jev/ett), Ralls, Rolfe, Oliver (Senator), Sops of V/ine, V/ashington Royal, V/inter St. LavA'ence. Fertilizer iil.er:ient_s Nitrogen, phosphorus and potassiun are the elements raost often lacking for plant growth in soils in the United States. Other just as neces- sary mineral elements are usually present in sufficient quantities to ade- quately supply the needs of growing crops, including fruit trees. However, it is interesting to note that a lack of one or r.iore of the so-called minor elements produces consequences of real ecouor.iic significance in some fruit sections. Some of the lesser knovm deficiency symptoms and rer.edial appli- cations are as follows; leaf mottling and rosette of peach, citrus and other fruits in California, apple trees in V/ashington, pecan trees in the South - Sine J chlorosis and rosette of peach trees in South ^-ifrica and die-back of citrus in Florida - copper^ chlorosis of citrus in California and Florida - manganese ^ chlorosis of many plaircs in r»any parts of the country on high calcium soils - iron; internal cork, rosette and die-back of apples in many sections - boron. There are undoubtedly other exaraples. It is consoling to realize that for fruit trees on inherently good and well- handled I.Iassachusetts soils, nitrogen is usually the only limiting factor. Under a heav^'- mulch system, even the usual nitrogen applications become less necessary. L^ Southvdck Suggestions for the G_ood^ _of_ t]!®. .AZl1§.. Jil^.V.^J'^J'i Of possible interest to I.assachusetts fruit growers are the remarks of Senator Harry ¥. Byrd, who spoke last December 6 at a meeting of the Vir- ginia State Horticultural Society at Roanoke, Virginia. Senator Bird is one of the largest orchardists in the country. Spealcing of what can be done to improve our fruit situation, he m^ide these suggestions; (l) "A Virginia and a national cai.ipaign to cut dovm undesirable and unprofitable apple varieties." (2) "Sliminate unprofitable marginal orchards bjf a voluntary negotiation with the owner, and financed by some method of assessm.ent on all apple producers." (3) "Agreements not to sell cull and inferior apples in competition v/ith packed fruit." (4) "Promote an apple juice, sold fresh and pressed from fresh apples by a machine just invented." (5) "A general advertising ca:?.paign em.phasizing the health giving qualities of the apple > an educational cainpaign to teach the consumer -3- the merits of different varieties for different puri^oses." (o) "The box, v/itli individually UTap;;ed a;^:;^-los, should be standardized in size." L. South wick SPJi' -Sil^- .s.nd Pr°P,??-^'^.'' _°?_ Fruit Results this pa.st season indicate considerable proi.-dse in the use of dilute concentrations of certain compounds (so-called horuones as ex- plained in the last issue of Jruit llotes) to dele>.y fruit drop at harvest tine. At the '.Vorcester iiieetin^^s. Dr. J. R. tiagness of the U.S.D.A. gave a brief account of the situation, h'aphthalene-acetic acid at 2 - 5 parts per million of water — approxi:.iately l/l5 - l/5 ounce in 250 gallons — is reported to reduce and delay significantly the normal dropping of apples at harvest tine. The spray is applied very thoroughly — up to 25 gallons per tree — because evidently it is necessary to hit each a.pple ster.i. One or possibly two applications will probably be adequate 5 (l) when the apples are just starting to drop in Septer.iber, and (2) about 10 - 14- days later if desired. Effects s.re first r.Tanifest about 24 hours after the spray is ap- plied and persist iron 10 - 15 days. Naphthalene acetandde has ooen slightly nore effective than naph- thalene acetic acid, but it does not go into solution as readily. It is possible that a conirnercial product using one of these niaterials will be put on the :-.iarl:et this year. The corapounds are expensive at the present ti:.io but it has been suggested that the cost of the diluted spray nc.y range some- where around a cent per gallon. This would neaxi. a cost for :.a.terials alone of 25 to 50 cents per mature tree. Then there is some evidence that a light surm'iier oil and the addition of citric acid may increase effectiveness. There is evidently no danger of toxic effects on consuj-.iers . All of the statements and figures given are, at best, approximations. I.'ore definite inf orir.ation v/ill be forthcoming later and especially after anoth- er year of sxperinental v/ork. In the neantirne, it is worthwhile to speculate on the possibilities that this development presents, particularly to grov/ers of Mcintosh. If application of these horaonos vrorks out as indicated by preliminary experiments, growers v/ill be helped considerably not only in the decreased total ai'nount of dropping but also in the better maturity and in the improved color that the longer autui-;in exposure will bring about. Probably growers should not expect to use these sprays generally over their entire plantings, -iilcononicallyj they may be more justified in cases of emer- gency when serious loss fromi dropping threatens. These are only conjectures but certainly worth -Dondc-ring. I.Iore information later. ,, . , L. Sou'jnvjick ITi:;i:IS FRCI.: KiCRE AilD THJRE Ej uJJ;_ F ljuit_ P_atent_s .

Larger average combined production of all tree fruits in the U. S. is expected durir.g the next five years than during the past five years. Significant increases vxe expected in grapefruit, oranges, lemons, and moderate i:icr eases are expected in peaches, peai's and cherries. Grape production vri.ll increase slightly but apple and prune production is expected to continue dovmward at a moderate rate.

Tukey expresses the situation in a recent issue of the Rural New Yorker. Ke says that r.uch of our troubles begin because we as producers try to resist this clianging situation by such natural ir.nulses as denanding what we call "cost of production." He sites the exarq le of an iceberg meeting a ship. "T.io iceberg goes on just the san;e." The iceberg typifies the demand of tlie i/iarkot, and the ship, the producer who atteu^rts to run crosswise to consuner deniand. Ty/Q _Poj.nt_ejr_s_ f r_on]_ _I_C'._euio_ - Glancing through the January News Letter of the University of Idalio, we note those two suggestions, (l) Stressing the need for using old strawstacks to best s,dvantage, a vrriter says "Don't burn theu or let then stand out in the field. jJxperiivients show that straw mulched fields hold 3 to 4 tines as :.:uch water as bare plots." Speaking of a snail gully, the m-iter says "Seed it, fertilize it, mulch it, and v/atch the grass choke the gully to death." (2) L. Verner of the Idalio Experiment Station offers this advice about pruning raspberries. "Tlie previous behavior of the plant, as indicated by its vigor, is the best index of how severely to thin out and head back raspberry plants. Thin sxid head the weak ones rather severely but give the strong ones plenty to do by leaving more fruiting wood on which to bear." SjDi_lj__fpr__Blv\ebprri^^. In the last issue of the Rural hew Yorker, S. John- son of Lichigan says, "Tlie blueberry plant is almost always found growing naturally on sand or peat soil. However, it v/ill grow satisfactorily on soil containing soaie clay if sufficiently acid. The soil ii^ist be very acid. A pK range of 4.4 to 5.1 seems to be best. Blueberry plants vri.ll usually survive a flooded soil but if too m.uch water is present after root grov.th starts the pls-nts are likely to be injured and if excess v/ater is present for too long a tine the plants vri.ll almost certainly die. Plants growing in poorly drained areas are more subject to heaving and are more suscepti- ble to frost injury < Too little moisture results in smaller growth and decidedly lov/er yields.

The Soil Auger will serve as a clearing house for information per- taining to soils and their use. In the first assue there appears an in- teresting story entitled "The role of calciur.: in the soil and the plant." An abstract of this a.rticle will appear in the next issue of ?ruit Notes. The Apple Storage Situation. Slightly fewer apples were in cold storage in the United States on January 1, 1940 than a year ago. At the sa..ie tiue, Massachusetts had nore than twice as nan'y as a yeai' ago, with 954,000 as compared with 445,000 in 1939. Sonewhat sualler stocks are in storage in the North'./est than a year ago. On Jc.nuary 15, according to Y/. ii. Piper's Iiiarket Report, v;e v;ere still holding 340,000 bushels of I.'clutosh in Massa- chusetts, having rroved 51;i of -che crop. A year ago \/e still had 122,000 and had moved 60/i of the crop. In the three previous years we had nov ed by January 15, 46/0, 51^0 and 40/op respectively. The above figures suggest a ver^' goodi Ilclntosh .■.loveinent although './e still liave p^lenty of that variety left in s-corage. 1 OjlP 0P_ i-i-iis • Fall and v/inter purchases of apples by the F.S.G.G. through- out tne U. S. up to January 21 have aiaounted to 10,135 cars. This does not include 500 cars purcha.sed for drying. Iitssachu setts sales to the F.S.C.C- have amounted to about 255 cars during the saiue period, including 70 csjTS of Ilclntosh rioved out of storage. ATrain Lo_ad_ a Daj.

FRUIT H0T3S - February, 194-0 W. II. Thies !]xt ens ion Hor t i cul tur is t It's Pruning Time Many of the apple orchards in Massachusetts have too many trees per acre for best results. Unlike a planting of for- est trees ivhere some crowding accompanies best timber production, orchard efficiency is highest when wo have onl;^ enough vegetative growth to best utilize the available moisture, mineral elements and sunlight. Anything in excess of that ideal amount, particu- Ic'.rly in the form of surplus trees, is a distinct liability. Twenty-seven mature trees (planted 40 x 4-0) on an acre of land will need to produce only a little more than 11 bushels per tree per year to insure 300 bushels per acre, a fair average. Twenty- seven trees, with ample space for root develop.aent and a good exposure to sunlight on all sides (natural accompaniments of proper spacing), will produce 300 bushels of apples more chec?'ply than 54 trees on the same area. In the latter case, available resources are wasted in developing v^ood too far from the ground and in setting fruit buds under highly competitive conditions. Other reasons for reducing the number of trees are ob- vious. There are fewer trees to spray, fertilise, prune, and thin, thus saving in labor and materials. More of the fruit may be picked from the ground, since the lower branches are kept vig- orous and productive v/hen a tree has adequate space. This re- duces the cost of harvesting. Color, size and quality are likely to be better since vrater and nitrogen are very often limiting factors, and these materials are used needlessly in a crov/ded orchard, in merely maintaining surplus vegetative growth. Any orchard should be considered as having too many trees if they interfere in any way with the movement of the spray- er. The ideal arrangement is found where there are just enotigh trees, evenly spaced, to reach into and utilize .the belo"w ground resources without serious competition, with tops neither touching nor shading each other appreciably. Probably the best recommenda- tion for prompt roraovol of surplus trees comes from those v.iio have tried it. Many who have waited for "one more crop" before wielding the ax, wish they had acted sooner. The removal of entire trees may be considered as one very effective kind of pruning, since pruning is the elimination ) Issued by tlie Ziitension Service, Willard A. Mimson, director, in furtherance of Acts of May 8 and June 30, 1914, Massachusetts State College, United States Department of Agriculture, and Cotuity Extension Services cooperating. -2- of miv/anted wood and surpliis trees are in that class. Of course, v.'e still have the annual puzzle of deciding which branches to remove from the permanent trees, but that is less difficult v/here each tree has ample space. In trees 20 years of age or older, drooping, shaded branches or parts of branches should receive attention. And occasionally a vigorous, upright growth should be removed where two or more are trying to occupy the same sp'^ce. Little, if any, heading back is required, since well spaced trees are much less likely to grov/ too tall. Heavy, annual crops help tremendously in keeping trees from grov;ing skyi,";ard. Any discussion of tree pruning would not be complete without stressing the need of carefu]. training daring the first fe\7 years. Rapid grovYth, plus an occasional corrective cut before the tree is five years of a.ge will work wonders in developing a strong framework, as for example, in a loader type of tree. The ease of pruning such a tree in later years is ample reward for the attention it receives while yoving . The Role of Calcium in the Soil and Plsnt (Abstract of an article in the January issue of Soil Auger by W. S. Eisenmenger) As far as our present knowledge of plant nutrition is con- cerned, no element acts in more capaci'cies than does calcium. We apply cflcium to the soil in the form of lime for the purpose of changing the acidity. But the calcium has another important effect, Calcium makes the soil loss compact and therefore easier to culti- vate. This attribute comes into play especially in clay soils. A compact soil is not V'ell supplied v/ith oxygen and it harbors unde- sirable rather than useful bacteria. Calcium is admirably adapted to penetrate compact masses and is therefore an antidote for caking and matting. This characteristic also allov/s it to poss out of the soil rapidly, particularly from a sandy soil. This is showm oy the fact that rivers in humid areas contain much calcium. It is inter- esting to note that more ground limestone is required to neutralize the acidity in a clay soil than in a sandy soil. A ton per acre may suffice in the latter \7hil0 the former may require three tons. Calcium also tends to increase the availability of other elements, such as phosphorus. A clay or loam which shov/s little available phosphorus when the pH is as lov; as 4 or 5, v^rill sliow a much hiigher phosphorus content when it is brought up to 6 or 7 by an applica- tion of lime. Thus we find several important functions of cflcium in the soil, while in 'che plants themselves its functions are of tre- mendous consequence. All of the higher plants require calcium. Fungi thrive witliout it, while mosses, lichens and ferns require a small amount to sustain life. One of the more important fec"tures of calcium is its abil- ity to overcome, toxicities v/hich would otherwise harm the plant. The presence of superabundant amounts of magnesium, aluminum, iron, copper, boron or zinc and the ensuing bad effects are overcome in part by calcium.. This aspect of calcium is illustrcted by the less- "3- ened efrect of e boron application on a limed soil. Calcium also neutrE.lizes acids v/ithin the plr.nt and precipitates them out as insoJ.uble cclciura salts. A calcium deficiency is manifest by a flaccid condition of the cell walls with sometimes a bending dovm- ward 01 the leaf tips. Legumes are regarded as conservers of ni- tro[_,en but they also remove large quantities of calcium from t?ie soil. Calcium is the one element most often lacking in the animal diet. And sirice a glass of milk contains more calcium than a similar volume of saturated lime v/ater, calcium must be an im- portant item in the animal diet. This element is therefore of great importance for both plants and animals. They're V/orking On It In the January issue of the Experiment Station Record we find brief abstracts of investigations in pomolo,^;' &s f ollov/s : (1) Leaves grov.'ing on a vigorous 25-year-old Mcintosh tree are found by E. P. Christopher of R. I. to differ but slightly in their rate of CO2 assimilation \mether growing on "thick" or "thin" branches. V/hen a leaf growing on a thin branch was so placed as to receive more light Lhan the corresponding leaf on a thick branch, it sliowed a marked gain in assimilation. Thus it appears that the inefficiency of the slender shaded branch is due not so much to fruity conduction as to a lack of light on its leaves. (2) The effect on pollination of c copper lime dust ap- plied at blossoming time for fire blight control is being studied by MacDaniels & Ili.ldebrand of Ilev; York State. Paired blooms on 25- year-old Northern ,Spy trees pollinated with Delicious and then dusted, failed to show detrimental effects of the copper on fruit set. But the application of the dust 24- hours prior to pollination was detrimental. This suggests that copper compoionds may be applied to apple blooms, if necessary for blight control, v/ithout seriously reducing the set. (3) Thinning of Wealthy blossom buds at the pink stage to a distance of 10 to 12 inches apart is found "oy Bobb & Black of New Jersey to have a marked influence on annual bearing in 19- yecT-old trees. The immediate result of blossom, thinning was to stimulate leaf development on all spurs and to encourage blossom bud formation for the succeeding year. (4) Observations on 3 apple varieties in 1936, 2 in 1937 and 1 in 1938, by Ellenwood Ik Gourley of Ohio, showed tliat the most serious source of mechanical injuries v;as in the grader. The man- ner of emptying the picking container into the crate was also im- portant. The human factor wc s important with much viu-iation re- corded among pickers. It is suggested that sponge rubber or other padding should be used in the bins and tables of the grading machine. (5) Supplemental irrigation of apple trees growing on a deep, porous soil which received 22.7 inches of rainfall was found -A- beneficial by Wiggans of Nebraska. Soil samples collected through the year in a block of Delicious spaced 30 x 33 feet showed that the rainfall vifas insufficient for both trees and cover crop and that 15 inches of irrigation was necessary to meet all requirements. Records on 7 varieties sho«ved an average of 9% of apples below 2-2-" on the irrigated plots compared with 4-4^ on the non-irrigated plots. Does Internal Cork Disappear in Storage? There seems to have been some difference of opinion among fruit grov/ers as to whether internal cork becomes more severe in storage or not. As a means of finding a possible ansvrer to this question samples of Mcintosh apples were taken from certain orchards in Middlesex County v."here internal cork v;as particularly trouble- some. These apples were then sent to the Pomology Department at the State College for observation. On September 26 a composite sample of the apples was divided into three lots. One lot was ex- amined immediately to determine the amount and severity of internal cork at harvest time. One lot was placed in cold storage and the other in common storage. On November 25 one-half of each lot placed in storage was examined and the other half was allowed to remain in storage for further observation. On February 1, the final lot was removed and examined. A small sample each of Cort- land and Baldwin was treated in a similar manner. The results of this experiment suggest the following conclusions: (l) Apples that are free from internal cork when placed in stort^ge do not acquire it. (2) That internal cork in- creases in severity the longer the apples are held in storage. (3) That there is no relationship between the type of storage, whether cold or coimnon, and the increase in severity of internal cork. (4) There is no evidence that apples affected v/ith internal cork when placed in storage will ever recover from it. As a supplementary p^rt of this experiment the effect of internal cork on the cider making properties of apples v/as studied. In this experiment apples showing none or a mere trace of internal cork were compared with those sliowing medium and heavy amounts. The results indicate that apples show^ing internal cork produce about 10$^ less cider per unit of fruit than sound apples. Also, the cider from corky apples has more sediment and is less acid than that fro;, sound apples. 0. C. Roberts February Cold Storage Report According to the Agricultural Marketing Service, cold storage stocks of apples were reduced 5,886,000 bushels during January. For the same month in 1939 the figure.. was 5,593,000 and for the 5-year average - 5,297,000. Stocks on hand February 1, amounting to 20,312,000 bushels, were 661,000 bushels less than those of a year earlier and 1,64-9,000 bushels below average.

Scuthv.'ick V/eight of Bushel of Apples V\'. S. Campfield, secretary of the Virginia State Hort. Society, undertook the accurate weighiing of some 500 commercial bushel packages of apples to find the average deviations from the commonly accepted bushel weight of around 42-5 pounds. Average weights, several varieties included, vi^ere as f ollov.'s : Northwestern packed box 1-1/8 bu. Eastern box - face and fill 1-1/5 bu. Eastern crate - either face and fill or packed Evans drum - face and fill Basket - Crovm cover - face and fill 43 . 7 pounds 45.7 " 47 . 7 42.5 4>3 • ' Mr. Campfield says; "I would think the northwestern box and the Evans drum more nearly indicate the weights of a bushel of apples. It will be noted that the other packs, including the bas- kets, were all in excess of the bushel weights, and to that extent, the industry is giving away to the trade more apples than it should, due to the use of so many to say nothing of the to 1 chaotic condition different sizes and types of package.

L. Southv;ick Plans Available for Orchard F.guipmenc and Apple Storage Structures Some time ago, V/. C.

A limited number of blueprints ;-:re still available from Prof. Harrington's office at a very small charge. Shall ^Ve Count Our Apple Trees? In 1925 a valuable inventory of apple trees was taken, in Kew England. 1754 Massachusetts farms were foioiid with 100 apple trees or more. The survey covered not only tree numbers, but ages and vorieties. With the hurricane removing large numbers of trees in hew England, it has been suggested that we should again take stock of our apple tree resources. Many changes have taken place during the past 15 ^''ears. lb \'Ould be interesting to know vmether or not we no',»' have too large a proportion of Mcintosh, and also the extent to which apple trees ^re being planted for replacement. Profitable Pest Control Conference in New Haven About 25 entomologists, pli.nt pathologists and others in- terested in fruit pest control in hew England and hew York met at New Haven, Conn., Feb. 8, for an all day conference to discuss nev; developments in materials and control methods. Among the points brought out v;ere these: The modern, stream lined, high pressure, high speed sprayer is permitting certain minor pests like bud moth and leaf roller to increa.se in numbers. Loaves may be blovai Imt not entirely covered. The grov/er must become better acquainted v/ith the life history of the pests present in his orchard. Promis- ing results wore reported from the use of derris dust for apple mag- got control in Connecticut and of cryotite for apple curculio con- trol in Zlew York. -7- Massachusetts p.

P'^rt of the lov.er Connecticut Valley wcs surveyed in 1899. -Plymouth County was mapped in 1911. After some delay during the Vvorld War, mapping was re- sumed in 1920 and continued until, v/ith the surveying of Frj-nklin County in 1929, the state was completed. Maybe That's How It Started V'e had alv^a^AS supposed that "strawberries" v.'ere so named because straw was conu-nonly used for mulching. But the folj.owing statement from the French Gardener of 1691 melees us wonder if the origin of the name may not go back to the ancient custom of tying the plants with straw: "You must dress, weed and loose the mould about the plants very diligentl:/, and to have fair and clear fruit, 3'ou shall stick a small prop to every pl^.nt, to which you shxll bind their stalks v/ith a straw. " Do Lcrger Yields Mean Softer Fruit? At p recent fruit meeting, a grower raised this question: "Are we getting softer Mcintosh as a result of our efforts to get larger yields? The answer is a qualified "Yes." A nitrogen starved tree has smaller, firmer, more liighly colored apples, and fev/er of them. A tree vfith an abundance of nitrogen, plus a good water supply, bears larger and generally softer apples. Some of them m.ay be poorly colored. If we can't get both high yields and ideal color and quality, let's compromise between the best possible yields consistent with other desirable characteristics. Large annual yields are of primary importance. And incidentclly, let's give more attention to packages and methods of handling which will insure good m.arket condition in a naturally soft apple. "Poor Ma n ' s Mul c h " is a term sometimes applied to snow. As this is being written I'e're gettiiig another heavy snowfall on top of the 9" blizzard of February 14- Here's hoping its Vc.lue to the "not too wealthy farmer'' may be in proportion to the amount now covering the landscape. It remains to be seen what in;iury, if any, may have oc- curred during the contin"aed cold v/eather during January v.iien the ground was bare. A good mulch not only protects the roots of plants by preventing deep freezing, but when it disintegrates it yields to the surrowiding vegetation something of real value. In the case of organic matter the products of decomposition not only improve the texture of the soil and increase its cbility to retain moisture, but provide nitrogen and other mineral elements. Snow, if it is to live up to its reputation as a mulch, must also yield sometl:ing of value v;hen it disappears, namely W'ater. 3ut v/ater is of no use unless it soaks into the soil tnd is available v;hen needed. v,"i£,t runs down into the valley may be worse thf.n useless. Melting snow over deeply frozen ground can scarcely qualify as a good Liulch. But if tiiere is plenty of organic matter beneath the snow to prevent most of the surface runoff then it contributes something of vital importance to the fruit plantation. Ixo'l FRUIT LIOTZIS - March, 1940 W. H.

For the first time in a number of years the meetings are to he held on Thursday and Friday instead of Tuesday and Wednesday . This change has been made in order to avoid a conflict v.'itli the Farm and Home Vfeek meetin[:,s in Connecticut. Details 01 the program are nov; being worked out. In addition to another interesting speaking program, an o:-hibit depicting the histor:' of spraying equipment v/ill be on display. Changes in the 194-0 Apple Spray bchedule The 194-0 Apple Spray Chart, available from each County Extension Office or from the State College, contains no radical changes. In addition to a nev; color scheme (pink instead of brov.n) nev; emphasis is being placed upon wet'cable sulfur in the earlier applications. Hot that apple scab is any easier to con- trol than it used to be, but because of improved equipment and better timing of spray applications, more grovers are able to rely upon a v/ettable sulfur for sorb control, using lime sulfur only in an emergency. Note 2 in the 1940 Apple Spray Chart sums up the situation. The new spray chprt also outlines detailed control m.easures for two m.inor pests, bud moth and leaf roller, v;hich seem to be on the increase in certain orchards. liotes 4 and 5 suggest how thfe as pests are best controlled. Bees for Pollination Proj-^ct A joint project betv;een beekeepers and fruit growers in Massachvisetts has again been arranged by the two associations for the purpose 01 facilitating the rental of strong colonies of bees for orchard pollination. The specif icctions for a colony for pollination purposes agreed upon b^ both beekeepers and fruit growers is as follows: ''A nori.ial over-v/intered colony consisting of not less than six frcnes of bees with brood in a ten frame hive." The interests of both- beekeepers and fruit growers have been carefully considered in •^he arrangements as nov" dravm up. April 10 has been set as the closing date for the agreement be- tween beekeeper and agent of the M.F.G.A. For full details, growers are invited to com.municate with \Y. R.

Planting a Nev/ Orchard? To be impressed v;ith the seriousness of the erosion proh- lem one\ needs only to see a side lull orchard v/here erosion over a period of years has raised the soil on the lovver side of the orchsrd as much as 2^j feetj, as evidenced by the difference in soi]. level on opposite sides of a stone wall. That situation acoually exists in a Connecticut Valley orchard. Constant cul- tivation up and dovm the hill plus potential gulli.es started by wheel tracks^ have almost ruined the upper half of this area. Such situations stress the need for contour planting on sloping areas. This applies particularly to peach orchards although contour apple orchards should become more common in Massachusetts. In addition to the conservation of vvater and soil^ another big advantage in this method is that it enables one to travel "on the level" with the sprayer or other orchard equipment. Service is now available for any grov/er v;ho contemplates a contour planting or v;ho is interested in means of preventing erosion in present plantings. In Massachusetts, A. B. Beaumont is in a position to give assistance in matters pertaining to either erosion control or contour planting. Any interested grov/er should confer with his county agricultural agent. Increasing Strawberry Yields Joseph Rose of Falmouth has a reputation for being a good strawberry grower. His yields are far above the average. One is impressed by the appearance of his plants and by the spongy feel of his soil due to a generous supply of organic mrtter. On in- quiry, we find that he rackes a practice of plowing Lmder three cover crops before the strawberry plants are set. Here are his sources of organic matter: rye, corn and buckv:heat, and millet. Liberal fertilization of these cover crops gets his soil in siich excellent condition as regards reserve fertility, retentiveness, and aeration that he has much less need for stimulation of the str£a;berry plants after they- are s^': out; He hrrvests around 12,000 quarts per acre. One Grower's Idea of Stravrberry Varieties A. W. Love of Auburn lias experimented a n^omber of years Y'!±th various varieties of sm-'ll fruits and on the basis of his experience has this to r&y about strawberries: Catskill tcKes number one rank "without the slightest question." Aberdeen is good for the "pick them yourself" tvfjde v.-hile the Howard 17 pro- vides some early berries". Ke thixiks the everbearers have been misnamed as far as his location is concerned. They should be called "never bearers." For reasons v/hich are not entirely clear, he finds that raspberries do much better on a north or northeast slope. Low temperature injury to canes in spring may bo a factor. "Ilever agrin," he says, "will I plant on e southern slope or on level land. j]ven where the soils are equally well drained, tlie slope makes the differ-ence bet\"een success and failure." Any Mouse Injiiry? A heavy grass cover in many orchards alon£ vith ?. hecvy Ic.te v.'intcr snov/f all , have brought ideal conditions for mouse girdling of fruit trees. The ideal time to detocc such injury and do something about it is early spring. Timo spent in going over the entire orchard systematically may net big returns. Too often v;e relj/ upon the protection of wire guards long since out- grov.Ti "by the e::panding tree trunks. Mice often v.'ork belo'.v the v;ire guai-ds and in some instances above tlr:.em. Bridge grafting, if it can be done soon after the gii'dling takes plac--, is an ef- fective v/ay of overcoming the difficulty. Eu'C \;he girdling must first be observed and that takes time and patience. Incidentally, any orchard v,"hich shov/s evidence of mice this spring should be given the nevrl-.- c'eveloped poison bait treatment ne;:.t fall. Zour county agricultural a;^ent can provide the nececscry information. Hev.' Uses for Apples Speaking before a recent llashoba meetin,:, in V'estford, J. J. Willam.an of th.e :i]astern Regional Research Laboratory in Philadelphia, told of the establisliment of four regional research laboratories in search for ncv; and wider industrial outlets and markets for farm conmiodities and products. Research will be de- voted primarily' to those farm commodities in \;l:ich- there are regu- lar or saasonrl surpluses. As early as 1908 the Department of Agriculture published results from experiments on the preparation o:.' luifermented apple juice. The need now is for an apple juice which ",;ill retain indef initel"^ the flavor of sweet cidor in order to extend its use through the summer months when a thii'St q.Lienchin^. fruit juice is greatly desired. Among the many other uses oi cull and surplus apples, the follov/ing ma3' be noted: aried apple sauce for use in the baking trade, a taele syrup witli an apple flavor, wax from apple peel for use as r plasticizer in paints, and as a coating for m.imeo- graph stencils, a wider use of pectin, as for example, as an emulsifier or gum in flavoring and pharmaceutic; 1 preparation in medicine, in dairy, confectionery, bfkery products, in plastics, and in sizing textiles. In the above Itboratoi'y, work is being conducted, along a number of lines on a small scale after which pilot plant operations v/ill be undertaken. In the pilot plant enough of the product will be made for a thorough study of its usefulness and marketability.

Increasing difficulty vvixh codling moth control ]ias prompted this sup]}lemontary control measure. One gro'.vor reports findinr more than 40 codling moth cocoons in a single apple box. Ileealess to say, he found plenty of "stings" in the fruit at harvest time last fall. Removal of loose bark is quite essential if one is planning to use chemically treated bai.ds around the tr'unk. Only Dy removing the natural hiding places for the larvae can the bands be made most effective. An almost unbelievable number of larvae have been counted beneath codling moth bands in Massachusetts where this method of control has been tested by A. I. Bourne in recent years. V/e are inclined to think of the codling moth as of little consequence in this section, ".vhere our growing season is relatively short and the second brood is usually ratiier light. In regions farther souths where a full second and third brood de- velops, there is, of course, a i.iuch more serioiis problem. Put even in i;ew England, codling moth seems to be on the increase, particularly where the control program involves dust application's in s t e a d of s p r a y s . Two Simple Pruning tSuggestioris Seldom do v/e find tv/o people v.'ith the s&me notions about pruning an apple tree. The amount and kind of pruning is so tied up v'itn age of tree, vigor and variety that rifles are rs difficult to follow as thioy are to form.ulate. It is almost impossible to tell anyone how to prione because the "how'' depends so much upon "what" we have to begin with. If a tre-^ is leapt growing rapidly from the start and if i'^ had a "leader" to begin vrith, the chtnces are it will develop into a fairly strong tree. But very often something happens to check the gro'.'th of the feeder and subseouent grov.'th gets shvjnted into r i;horl of vigorous, closel-/ spaced side limbs. Such a tree, if allo\7ed to continue i;ithout corrective pruning, may have -cwo or three or more le&ders r.nd perhaps a v;eak framework. To correct •cliis situation, the whorl must be partially eliminated by drastic :io;.:.ding hick of some of tiie side limbs or preferably by removal of seme of thi-e side limbs entirely. The sooner this c^n be done, the better. Under nc- conditions should a side limb be allo-v/ed to outgrow' the leader. To state the matter in a different way, if a side limb of a very young tree shows un- mistakable signs of leadership, ia may be advisable to select that for the leader and to remove the jiortion of the tree origi- nally designated ss the leader. Cuts of this can be made at Z or 3 years of age and cciplecely ohcinge the fri,mev/ork of the tree without greatly retarding fruit production. But if the corrective pruning is delayed until the tree is /^ or 5 years of age it is almost impossibl'-' to attain the desired end. Our second suggertion concerns an apple tree 15 or 20 years of £ge or older which lirs borne heavy crops. Successive crops have bent the branches dov;nw.;,rd luitil some are well belov; the hori- zontE-l, v/hilo I; teral shoots hevs developed outward and upvi.rd. The pruiiinf, of such a tree may often be confined almost entirely to the remove 1 of the older pc rts of branches which Lirow more or less dov.-nward, retaining the 7oi.in:;,'?r, better exposed parts of those branches. In addition to tlie remov;:l of this older, more shaded v/ood, wc must, of course, occrsionally take out a crov;d- ing upright v/hcre tv/o or three are trying to occupy the Sc'.me space. in f^eneral, vjhen v:e prune older bearing, trees vvo should concentrate on the removal of "dov.TiriKhts" Inste.^d of "uprights.' Practices to Regulate the Fruit Crop Three prjcticcs L.re .Viov; receiving attention vrhich under certain conditions iuay be used successfully and proiltabl;,^ to regulate the apple and possibly other fruit crops. These are: (l) branch ringing to increase set, size and earliness of maturity of fruit, (2) spraying v/ith plant srov'tn substcnces to reduce pre-harvest drop of apples, and (3) sprayin;- to prevent fruit set in the on-year of biennial bearing Vc.riiities. It should be em- phasized that these rro not substitutes for any of our present major orcliard practices but only supplemontery to them. This in- teresting theme is discussed by A. 3. Murneek in the March, 19^0 American Fruit Gro'/or. This artic-le is "..'ell \;orth reading. Relation of Gprcy Pressure to Pest Control Some growers thinh the pendulum has svifung far enough in the dir..Tction of nigh pressure spraying. Tliero is some evidence to bear out this contention. V.'itiiin reasonable limits e::tra pressure is desirable since it breaks the spray into finer drops and carries it farther except v.-iiere air ctirrents prevent. The modern tendency, hovrever, is to over-emphasize the Vi. lue of e:;tra pressure. Leaves may be blo?/n but not completely covered. In the March issue of Better Fruit, mention is made of a conference in the State of V/ashington to consider all angles of this qiiestion. Tv;enty^ experts in various fields attended the meeting at vrhich the danger to foliage and even to fruit, wiiich may result from excessive pressure, v:as brought out. The v/arning on excessive pressure damage is coupled with the suggestion that growers pay more attention to orchard scnitation as an avc-:lliary codling moth control feature. It v?.s pointed out at the meeting that too muca pressure is z.s bad or worse than not enough. Large amounts of spray ere put on the trees unevenly in many cases and a substc.ntially better job can be done v/ith moderate or just enough pressure to reach the tops e;"sily. An Old Fertili.zcr Advert.isemcrit Brov/sin;:, through the March, 1912 issue of a Eev," England publication, v;e find reference to a nev; inineral fertilizer for which great claims were made. The ad stresses the fpct that this fertilizer contains 5'7fo silica, and then roes on to tell the per cent of silica in the ash of various plants, as for ex- ample, tobacco 18^, lettuce 20fo, and oats ^8%. From the analysis -6- of this fertilizer, about the only thing of ri.ctucl vi'lue is 1-^/^ each of potassium o:':ido and crlcium oxide. ICvideiitly this ma- terial v;s,s about as rich in plant food as th'; dust from a stone crusher. The ad closes v/ith this statement, "Tno n-.;v; mineral fertilizer means healthy and nutritious products whereas manures contain disease producing bacilli fnd debilitating ferment" (vmatever that is) . Modern farmers, with their better under- stcnding of fertilizer analyses i.nC. of plant requirements are in a more favorable position to judge the merits of the available materials. Chemistry and Soils Speaking on this subject recentl:/-, Ricliard Bradfield of Cornell University said, "It may seem a little far-fetched to see a chemist attacking a fertilizer problem by studying the reactions of fertilizer Y."ith colloidal clay in a test tube. But many prob- lems of fertilizer reaction ere very complex and can be clarified only by breaking them dov,Ti into simpler fragments. We have come to realise that v/hen v/e add fertilizer to the soil v/o do more than fertilize the crop with the ingredients contain'-n,'. in the fertili- zer b?c. By fertilizing the soil v/e set in operation a compli- cated series of reactions w'nich often require months, and even years, for their completion. In fact, it is doubtful if the soil is ever the same after a fertilizer cpplicrtion. The growth of the crops v/hich follow is influenced b--'' the Indirect as well as the direct reaction of the fertilizer." One Lesson from a Dry Season The severe drouth of 1939 whicii extended up to the har- vest season in the Mid-West has prompted some pointed comments from F. S. Hewlett of Ohio State University, ho sa^'s, "Evidence has been obtained from growers ul:o have irrigated, and tiierefore have paid close attention to penetration of v.-at:;r, concerning the effect of orchard tools ?nd equipment upon soil structure. One grower informed the v/ritnr that in no place in the orchard is satisfactory penetrcition of water observed except beneath the trees where the soil hcd not been trod upon or recently disturbed. The physical structure of the soil between th3 trees has become distinctly'- unfavorable -.s time h^as passed not only for v/ater pene- tration but also for root penetration. This might not be of great importance in a soil ^.'here rooting is comparatively deep, but in soil where aeration is naturally' shallov; it is of rather serious consequence. In suci: orchards irrigc.tion is almost essential and good v/ater penetration is obviously desirable. This fact emphasizes the importance of limiting the use of heavy equipment in the orchard. It rc.lso ccli: for ci\e adoption of a system of soil management vaiich maintains a structure of the soil favoring high water permeability, better aeration, and more extended root grov/th. The drouth has given some indication of those portions of existing orchards wliere mulching should be (.;arried out. It has brought out the advantages as well as tlie limitations of mulching. V'.T:iere trees have been mulched, loss severe effectsr I ■ have been obs-jrv.v^d. Yob obviously mulchins clo?3 not add water to the soil c.nd v/.'-ere rooting is very shallov: simply delays the be- ginning of \vater stress. Tliis d^alay is very desirable and may be the means of carrying 'crees through the drouth if not too pro- longed and thxe trees not too shallov; rooted." A 7-Point Program G. A. Drevr of Westiord offers these pointed susrestions in a recent issue of the Rural How Yorker: "Vniilo the cash re- turns from this last season's crop of fruit h.ave been rather disappointing, most of us fruit grov:ers still have faith in our business and believe it to be fundamentally soiuod. As to how best to meet the changing conditions and improve our positions, I believe the follo\7ing points should receive serious attention: (l) Cut do'vn or destroy our m.arginal orchards. (2) Eliminate varieties that are no longer prof it?-.ble. (3) Try to grov.' a large percentage of better colored, attractive fruit. (4) Eliminate culls from the fresh fruit market in open competition with our better grades. (5) Pack, handle and supervise the marketing of our fruit in order that it may roach the consumer in better con- dition. (6) vrnenever possible diversify more in several varie- ties covering a longer seaso:i or in different crops of fruit and not have all one's eg^.s in one basket. (7) Give our IJev/ York and Hew England Apple Institute better support in advertising our proauct. Tnis is my seven point program for recovery, which I respectfully submit." Small Fruit hotes from Hew Jersey J. H. Clark of He-.; Jersey, writing in the State I-orticul- tural Society Hews, says, ''.\n increosing niimber of Hew Jersey strawberry growers are using mulch e£-.ch year. The manager of one of the important produce auctions in the stc te recently made the statem.ent that the strawberry growers who go not mulch are losing m.oney by not doing so." Concerning raspberry varieties, he says, "The Latham, raspberry although quite susceptible to mosaic, anthracnose, spur taligh_t, etc., is the r,iost profitable commercial variety for iiew Jersey. Varieties more resisornt to disease end of better quality are badly needed." Internal Cork and 'Boron In the spring of 1937, boron applications were made to certain Mcintosh and Cortland trees in an orchard at Massachusetts State College which produced considerable corky fruit in 1936. ethers were left as ch.ecks. Borax was applied both in direct soil dressings and injections and in spra^'-s at the rcte of less than 1/2 pound per tree in each case. A check on the 1939 crops re- vealed the presence again of considerable internal cork in both varieties wiien untreated but no evidence of cork in. the fruit from tJie trees which had had borax applications in 1937. This evidence is in line w'ith other data and further substantiates that the cor- rective influence of a single boron addition may continue for several years in some soils. It likewise brings out the important fact that in the use of boron, a little goes a long way. L.

Su;--;p;esti_ons on Transiplantin," Trees Too often eui air pocket is left iiTJuediately under the roots of the newly planted tree. Intimate contact botv/een roots aiid soil nay be accomplish- ed in several ways, according to H. B. Tukey of the Geneva, Kev; York, Agricul- tural iixperiinent Station, but its importance cannot be overemphasized. E. S. Goff of 'Jisconsin in so:..o of the first sciontiiic studies with fruit trees in America showed the ii^iportance of water. Newly set trees supplied v;ith water through a rubber tube attached to a root, developed foliage much more ra-^ddly than untreated trees. The so-called "Stringf ellow :.ethod", devised about 1900, in rhich the roots v/ere trir-i.ied close and ran-aued into place seems to have been successful because it placed the roots in intimate contact v;ith the soil. A good pleai is to throw a few shovels of top soil into the center of the tree hole, place the tree on the conical cushion, covor the roots lightly, aiid tamp the tree f ir; '.ly into place. One of the advantages of using a peat soil mixture is th^.t it results in a springy although tight cont;:ict of soil and roots. The old m.ethod of pourxn^ a pail of water over tlie soil when the tree is planned is helpful largely beca.use it causes the soil particles to flov/ together and around the roots besides supplying v/ater directly to the roots. There is no better m.ethod of comp3.cting soil than by v/ashing it v/ith water. European planters still cling to the old method of dipping the roots in a heavy mud mixture before planting. The advantage of this m.ethod, if any, seems to lie in placing finely divided particles with a large surface area in intimate contact with xhe roots thus providing a connecting link between the roots and the soil particles. Want_ed_ - A I.iagic V/and . All of us are interested in easy v/ays of doing hard tasks. Often the search centers in a new material. Is 3.pple scab troublesome? Then I must try tnat new highly advertised materic.1. Is the fruit green and of poor keep- ing quality? I \7onder what fertilizer cor.bination v>dll correct that. One in- dividual inquired about this m.agic chemdcal for making fruit stick on the trees, when maggot was actually the causa of the difficulty. For fear of being ;;is- understood we hasten to say thf.t some of tiiese new m.aterials are extremely prom- ising and will undoubtedly find a place in our managei.ent program. But there seem.s little to gain by treating the orchard floor for apple scab in 1940 when the real trouble in 1939 was a co!.ibination of breakdown of the sprayer at the Pink Stage and a scanty coverage in tlie other applications. The spray program offers an opportunity to "put first things first" and to bring about a proper balance between timing, tiioroughness and '".laterials . TreoE worth .;op grafting i'.ro also worthy of atte::ition afterward.

The best arrangement of heaters is one in the center of each 4-0-foot square. If a temperature near the critical point threatens, every second one may be lighted, reserving the others for later use, if needed. Some growers prefer a low grade fuel oil instead of crank case oil because the latter tends to boil over if i': contains much water. This is somewhat ob- viated oy filling the pail only half full. Throe methods of igniting have been obsorvod, - a blow torch, a few kerosene 3oaked shavings dropped into the pail, or a strip of si'.iiilarly treated burlap hung over the edge like a wick.

"Better grading and sizin;^ are most important factors in influenc- ing consum.ers to buy apples instead of other fruits." "Federal Surplus Goirj-.odity Corporation purchases to April 15 for the 1939-40 season have am.ounted to nearly 9-^- million bushels. In cities v/here the Stamp Plan \ra5 used for relief distribution of surplus cormiodities, 5/o of the money y/as spent for apples, S/i for oranges, and 3-|fo for grapefruit." "Growers have a dsep affection for their cull apples. These ap- pear to be their most cherSied possession. Cull apples are gathered solicitous- ly, given an honored place on tho roadside or auction market, and they are offered first and only to the consumer upon whose favor the sale of the best apples depends." "A moderate increase in de;.:and with a reasonable diversion of the less desirable apples can result in prices that should bring a reasonable pro- fit to the average grower in good fruit sections. Twilifht Me9tin,e;s Once more the season of "orchard clinics" has arrived in liassachu- setts. At least 40 of ihese twij.ight sessions are being scheduled durin^^ the spra^/ing season for the purpose of looking over a good orchard and considering anything of tinely interest, with particular emphasis on fruit pest control.

Se_lection, Care, and Planting of i'urser./ GjQwy-, Fruity Trees This is che title of a new Geneva, New York, Circular (^^138) by H. B. Tukey, Grov/ers interested in knowing what is behind the trees offered for sale by the nursery should read this interesting publication. Here will be found a discussion of co;va-.;on nursery practices of interest to growers, grades and quality of nursery stock, bearing age trees, truenoss to naiae, patented planes, v/inier injured stock, bargain stock , types of nurserymen, rootstocks, handling ihe stock prior to planting, subsequent care, root form- ation, penetration and spread of roots, and the secret of obtaining vigorous shoot and foliage development. The European Red IlLt e_ Situation Scarcity of red mdte eggs in many orchards has resulted in a rather general omission of the delayed dormant spray. In only a few cases has a heavy infestation been observed. Probabli'' not more than a third of the commercial orchards ha.ve received aji oil spray this spring. The European, and other spider r.iites, according to V/» D. V/l:iitcomb, are generally described as feeding by "v/ounding .he surface of the leaf and lapping the sap v/hich emerges from the wound." They can feed on liquids only. By means of small, sharp appendages they pierce the cells of the leaf, although they do not have a hollow beak, such as apliids, through which tI:o sap can be pumped. Bronzing of leaves in mldsuriimer results frov.i the cell injury ..-.cntionod above. ::^*' L?.^''_ Control in Younr OrcIi:irds Folks oft oil ask about tuo niinimum nunbcr of sprays required on non-bcarlng fruit trees ^ Selc'oi.i is it necessary to api^ly more than throe sprays. But those tilings should bo kept in irdnd. Young trees if kept in vigorous condition by such practices as iiiulching, fertilization, or cultiva- tion, arc better able to withstand pest dariage. Peat control measures may be confined to those pests which threaten to injujre the tree. Only by constant observation can destructive insects be detected before sevf>re injury results. Some of these insects, including borers, require special treatment. A new bulletin (jf274-) from the University of L'ain^ "Insect pest Control in Young Orchards," by F. H. Latiirop contains- many helpful suggestions. The following insect pests are discussed- round-headed >^pple tree borer, oyster sliell scale, tree hoppers, woolly apple aphid, gypsy moth, leaf roller, tent cater- pillar, yellov/ necked and red humped caterpillars, fall webworm, brovm tail moth, European red irdte, and green apple aphid. Indians of Ancient Ti::i^e_s_ jlnev; j'j;i.iIi_Cui3;jali_o According to P. J. Ghapmsin of the Maw York Agricultural Experi- ment Station there irj evidence to show thab wild plums occupied an important place in the diet of certain Indian tribes long before Columbus' time. In 1534 Jacques Cartier, on his firLrc trip down the St. Lav/rence, noticed that the Indians had plui.is which thsy had dried for the v/inter. Of the tree fruits which v;e grov; today, the early Indians had only the v/ild American plu;.is which were also the original food plants of the plum curculio. Yi/here no control measures are practiced, the curculio is an exceedingly destructive past of both v/ild and cultivated pluiTiS . And if, as some v^riters contend, the Indians planted rude orchards of wild plujns, they j-.ust have knovm of the ravages of this insect. U. P. Hedrick states that thickets of wild plums coimnonly oc- curred on tliQ outskirts of early Iroquois villages. But whether the Indians maintained orchards of plums or merely collected the fruit afield, the dam- age caused by tlie curculio could hardly have been overlooked. A. C. Parker of the Rochester L.usoum of Arts and Sciences, says, "The picking and drying of the plums was done entirely by Indian women. Fruits wore split and pitted for drying. I have boen told that it was always necessary to remove tho worm fr.m tho plujn bcforo it was driod, the belief being that the presence of the worm v/ould cause the fruit to spoil. One in- formant said there were tim.es when e.ll the fruit was so damaged that no plums could be preserved. Furtlier, it was noticed that the fruit rotated in abund- ance;, some years there were abundant crops and at others none at all." Tills "wori.i" nouiced by the Ind:.c.n3 m.ust have been the larval stage of tho curculio. There is no o.hor comj-ion larva (worm) that infests the plura in this area. SOj while the ovidonco available doos not constitute absolute proof that ;-an's acquaintance vrith the plum curculio antedates the colonization of this continent by the -^li'Ge man, the probabilities seera defin- itely to favor such an assum.ption. In.jury to Ap-?le Trees fro/.'. Oil . 5j5ri?j_s Many orchardists are still skeptical of dormant or delayed dor- ■..lant applications of jil sprays. To be sure, oil sprays do injuro apple trees occasionally, es'-ecially when applied too late or when followed by uii- favorable weather conditior.s, bu\: uore often an unsatisfactory grovrth, which ifjajf have resulted from raouse injury, is erroneously charged to the oil spray. Tv/o ty;^;es of oil injury r.iay occur. (l) A distinct burning of the tips of the leaves in opening buds, and (2) The killing of the dorn^.ant leaf buds on one year old wood, such as terminals and waterspouts. The first type of injury is seldom serious unless the flower buds are burned. It is most likely to occur v/hen natari^ils for strictly dornairfc application, such as the dinitro compounds or strong coal tar oils, are applied in the delayed dor' .ant period. The second type of injury rnay result fror.i over-sprayxng while atteiT.pting to ^et thorough coverage in the v/ind, froi,: too great concentration of the toxic ingredient such as dinitro conpounds, and fron freezing weather soon a.fter application. This typo of injury nay cause r.any v/hip-like tvags with fev; if aiiy leaves oxco^.t c.t the tip, followed the next season by many fruit spurs 8 to 15 inches long with fruit buds at the tip only, instead of the normal fruit spurs 2 to 4 inches iri length. vV.

A. ilvans, 3xt3nsiGn iiintor.iologist of Cornell University, in- cludes this statei.-.ent in his latest '.7eekly News Let'^er concerning insect pests; "1940 is the year for anotiier big June beetle flight in many parts of ifev/York. Counts of overwintering beetles in the soil have shovm that as many as 100,000 per acre are present in some areas. June beetles fly in Llay, June, and July and feed on the foliage of oak, elm, poplar, birch or willow. Late in June they begin depositing eggs in sod land. In about thrue weeks these oggs hatch into grubs vjhich feed on the grass roots f.r parts of three years before ;^ reducing anotiior generation of beetles. Great- est damage by the gi'ubs is done the year after beetle flight. The m.ost se- vere daiiiage occurs when potatoes, cor;-, or other row crops are planted on land that was in sod during the year of beetle flight. Therefore, in grubby areas laiid to be used for such crop'S next year should be kept out of sod this year if possible. Investigations m other states and in Canada indicate that land planted to sweet clover, alfalfa, alsike, eaid possibly other legumes, is unattractive to the egg laying beetles. Land occu^ded by a good stand of such legumes this year can probably be safely used for row crops next year so far as grub injury is concerned."

Ingalls, former Kansas Senator, and quoted in the latest issue of The Soil ^uger oj A. B. -teaumont, may aaa their own wora of praise for the kina of vegetation which makes possible the ooa-wlulch system of orcharaing, ana maintains if given a chance, that m_ystic factor in the successful fruit farm, organic matter. Conserving iv-ianure on the Farm -tx very thorough uiscussion of this important subject is founa in a new Ohio Bulletin (No. 60d) by Salter ana Schollenberger. On the first page v;e reaa that the annual product of livestock on iimerican farms if completely recovered, carefully preserved, and efficiently used, shoula prbauce ^5,000,000,000." worth of increase in crops. The potential value of tnis agricultural resource is three times that of the nation's wheat crop ana is equivalent to i*;.440. for each of i^merica'a 6,800,000 farm operators. The crop nu- triments, if purchased in the form of commercial fertilizers, -woulo cost more than si:-: times as much as -h-merican farmers paia I'or fer- tilizers in 19b6. Unfortunately, only a small fraction or the, po- tential crop producing ana soil conserving value of this material is actually realized. Enormous losses occur in handling, through loss of nitrogen in fermentation ana arylng, the leaching out of soluble nutrients. The wasteful ana ineflicient methods of hanuling manure obvious in all sections of the countrj'- maybe taken as evidence that farmers generally ao not understana the true nature of manure ana especially the perishable character of its valuaole constituents. From extensive stuaies at the i\othamstea l^vrperiment Station in Eng- lana, ^mssell and J:^icharas concludes that manure keeps best when it is (1) thorougnly compact, (2) sufficiently moist, but not too wet, [6) under shelter, and (4) not movea. Lateral ivlovement of Potassium in an Orchard ooil That there is an appreciable movement of available po- tassium in the permanently moist strata of soil below plow aepth has been sho-An by ^ourley ana VVanaer of Ohio. They mixed 60-gram por- tions of a potassium salt with about two-thirds of tlie soil rem.oved from 18-inch borings ana placea it in the lower 1£ inch section of the holes, of which 16 were symiuetrically placed in 12 ana 9 toot circles, about each of 10 apple trees. Lateral movement oi the po- tassiiinx changea the available potassiim content of as much as 2.2 cu. ft. of soil arounu each hole from very low to very high. From i.'.i c. a practiccil stttriapoint , the authors say it weans "that potash- fertilisers coula be uroppeo oehina a aeep tillage tool, such as a Killii'er uisic or coulter to a aeptn or 16 to Id inches. This would be within the i.-ictive absorbing zone of the tree roots in most Eastern orchara soils anu also below the zone in which potassium is I'ixea 'cy alternate wetting . ana arying. Its lateral movement shoula then be ample for supplying the neeus ol the tree." ouch a practice woula, Ox course, be out of the question on a shallow soil, since deep tillage would destroy most of the root system. Some Factors Affecting the cropping of ^'Iclntosh Observations of the fruit in tv/o aajacent Mcintosh blocks oy G . n. ijickson, one of whicn the cover crop was sown about May 15, and in the other about tJuly 16, showea the percentage of drops to be greater in the late cultivated area. Increusea percent- age of dropping was correlated with higher nitrate supply in the soil, better growth of the trees ana larger total yielas. Color of fruit was much better in the area receiving less cultivation. The author believes that the behavior of the so-called non-aropping sports of Mcintosh may be aue to nutritional conditions rather than mutations or bua variations. The Vitamin C. (ascorbic i^cia) Content of Oerman -H-pple Varietie s /Chemical measurements of the -t^scorbic acia content of important apple varieties in Germany by V.'. i-.essler, show well definec differences sufficiently constant to be classed as varietal char- acteristics, out the content fluctuated within certain limits be- cause of locations, exposure, size of crop, etna fertilizers. Over fertilizing with nitrogen reauced tne amount, and in a given apple, it was greater on the more highly colored side, storage tempera- tures below 41°i!'. are necessary for tne retention of ascorbic acia over a considerable period. In general, apples of a given variety contained a larger amount when grovm in southern than in northern locations. The variety Ontario showea about the highest content of the many varieties tested. These investigations are reported in the German publication covering scientific agriculture, Gartenoau- wlssenschaft . The J'ooG otamp flan secretary of -agriculture henry ■^-. Wallace, issued a statement on the first anniveraay of the fooa stamp program, t^uotea in part; "k year ago today, May 16, I9b9, the fooa stamp plan began on an experimental basis in i-'-ochester . From that time until touay the program has been placed in operation in a total of 68 areas and 12 additional areas nave been designated for food stamp plan opera- tions in the near future Up to May 1, 1940, expenditures for surplus foodS v/ith blue stamps issued oy the Department naa a value of approximately |.10,400,000 Purchases of fresh ana dried fruits had a value of more than ^1, 700,000 ... .In the local areas now in operation under the statap plan, approximately l,b00,000 people are benefitting directly through increased ana improved uiets. ,. .Nearly a thousand coimnunities have applied for the stamp plan, vvithin the next few mxonths, it is anticipated that the food stamp plan will be extenaea to a total of about 125 areas, possibly 150 areas if smalle: towns are selected. It is our expectation that this exoansion will result in aaaitional purchases of surplus foods through" blue stamps alone, ranging from ?; 7,000,000 to Jew Jersey, Delaware, Maryland, Virginia, V:est Virginia, laaho, Colorado, Vvashington, and Oregon." i'^'*\:e Fruit Insect Observations The first apple maggot fly of the season was ooservea by V . h. vihitcomb in his V'/altham cages on June S5. oy July 1 a to- tal of 56 flies had emerged from the 500 pupae of last year.

Shaw A National Tree Removal Program A comm.ittee of tne Massachusetts Jrult Grov/ers' Associ- ation consisting of R. -a. Van Meter, R. ii. Peck, ana W. R. oole is cooperating vvith a national committee in a program aesignea to aid in the stabilisation of apple production through the removal in al3 apple growing sections of unaesirable varieties and poorly located orcharas. The situation is briefly as follows: The aomestic market for apples In fresh form is limited to approximately 75 milj-ion bushels if growers are to receive prices which are in line witn proauction costs. In the past five years the commercial apple crop has always been above 75 million bushels and reached 115 million bushels in 1957. There v/ould seem to be little chance for improvement in the foreign market in the near future. The fruit grower's income is too low for a satisfactory standard of living, ana the crop must be reauced if the efficient grower is to make a reasonable profit. Consumer's stanaaras of qiiaiity are rising steaaily. Cull apples sell more and more slowly at low prices ana tena to de- moralize the market for better fruit. The increase in pests, the equipment now requirea to grow good fruit, ana higher standards of quality aeraandea by consumers have maae thousands of small orcharas unprofitable. Given a minimum of attention or Vifholly neglect ea they yet continue to produce a quantity of low-grade fruit which is very large in the aggregate ana much of which finds its way to market, where it tends to cause grave aisturbances. Unaesirable varieties also present a problem. While the list of commercially aesirable varieties is not more than 10 or 15, no fewer than 80 varieties were offerea to F. S. C C. buyers aur- ing the winter of 19o9-40. Reauction in tne mimber of culls and in the nomber of undesir-able varieties ihas become a major problem of the industry. The National tonmiittee is maae up of four men: John Chanaler, sterling Junction, Mass.; C. h. i^utton, Milfora Center, Ohio; henry Vj. Miller, Jr., Paw Paw, w. Va.; ana Carl G. ^vooster.

Orchara Experiments in Ohio A recent report ol progress frora the Ohio i^xperiment station contains a large amount of information of interest to farm- ers, i'ollowing are a fev/ oi the items that shoula be of special interest to Liassachusetts grov/ers . 1. Apple foliage sprayea with lime sulfur showea a 2b% reauc- tion in leaf area as comparea to the b% reduction in foliage spray- ea v.'ith flotation Sulfur. £. uamage from the round heaaed a^^ple tree oorer was best pre- sented by covering the entire trunk witn newspapers folaed once and wrapped twice arouna the trunk. Oare shoula he taken that the cov- ering e]ctena3 clear to the grouna. This insect lays its eggs on the bark at the base of the tree from June to August. (The rouna heaaea apple tree borer is a serious pest on young trees in some orcharas in western Massachusetts.) b. When the grouna under i::'tdyman Vvinesap trees was coverea with canvas over an area 40 feet in aiameter from May 1 to harvest time, ■with means of preventing lateral transfer arouna the circumference, thus excluaing all rainfall over this area, the trees continuea to crop for three years in a satisfactory manner. This supports the contention that water deiicioncies ao not seriovly affect trees un- til the wilting point is approachea. It shoula not encourage us to believe, however, that v/ater is not essential to fruit oroauction. 4. Comparison of harvesting aates for rea strains, as comparea Y/ith the parent varieties, inaicatea that the picking date shoula be the same. This suggests caution Iti Licking rea oua sports too soon, even though they have reachea a satisfactory coloi' uevelop^ioit, J . K . S haw A Reminaer of the 1958 Hurricane Many grov/ers have remarKea that certain hurricane aara- agea apple trees look worse than they ala in tne summer of 1959. Dr. J'. K. chaw expresses the situation as follows: "Many apple trees are showing more eviaence of hurricane injury than they ala last year. This injury is eviaencea by sparse foliage v/ith a yellowisa tinge, suggesting the possibility of nitrogen aeficiency. Not only may the restricted root system be unable to secure suffi- cient nitrogen, for the tree, but the rainy weather may have leachea out available nitrates ana interferea witn nitrification. If hurri- cane aamagea trees show symptoms of nitrogen aeficiency, it may be ■well to give them a moaerate aose at this season perhaps half the usual appliciition of some reaaily available nitrogen carrying fer- tilizer. Tne sooner this is appliea the betteT-." Some of these daaagea trees sufferea more root breakage than v/as apparent at firsu, and have probably aone very little in the way of ueveloping replacement roots. Pernaps they pullea through the dry season of 1959 "on bcrrov/ea time" using materials stored in the tree. Tnen too, more nitrates may have been taken in last suianier. Vvhatever the reason for their sickly appearance, trees worth salvaging might well receive this aaaitional attention, (1) Make sure that the anchorage is secure ana that the tree is not al- lowed to sway in the v.ina, {n) Apply a quickly available form of nitrogen as suggestea above, (o) Kemove the apples, if any, in orcer that the manufactured food materials may be usea where most neeaed, ana (4) Use more mulch material. Western Grcvvers heconsider Old--Fasn:.onea Mcthoas "Olu-fciSiiione'a irxetl.oaa oi' spraying may be best after all," norticuiturlsts ana I'ielu men are telling grov/ers in the Wen- atciiee ana YaKima Valleys. To do a gooa job in the ola ciays, grow- ers usea a lonfi spray roa vvhich spreaa a fine mist over the tops of the treds. If' necessary the operator stood on a laader or tov/er. Recent tests show best results where coverage is attainea by close contact with a fine mist spray, insteaa of the high pressure, heavy stream spraying so common in this streamlined age. oo much attention has been'paia in recent years to complicatea spray luixtures that spraying technique has been given too little attention. Grov/ers be- lieve that longer spray rods ana spray towers will enable them to cover the tops more effectively. In fact some growers, vdth this modifiea system of spraying in mina, are planning to ao less prun- ing of the valuable bearing v/ood in the tops. Time Out'. You'd probably stop whatever you were aoing, also, if you came upon an occu.piea huimfiingbira's nest. Ana that's just what a group of 75 or more fruit growers aia auring a twilight meeting tour 01 the Join Chandler Orchara in bterling a few aays ago. The nost, with one egg and one bira on an apple bi-anch about five feet above the grouna, was viewea vvith real interest as folks passed in single file. The v/riter hopes that everyone got a thrill from this ornate bit of magic. Tnis is another ezaiapie of the unexpected ai- videnas v/hich appear now and then in the fruit business.

Meaals are a"waraea to club members v^rho show a yield rate of 225 or more crates of U. S. No. 1 strawberries per acre. Vigorous Trees Tena to Bear Annually The follov/ing information published by L. Greene of the Inuiana department of Horticulture bears out our observations that healtxhy, vigorous apple trees show a tendency to bloom ana set . fruit every year while weak trees are decidedly biennial, (.quoting from Hoosier Horticulture, "Fruit growers are always interestea in any recora of factors which influence the annual blossoming ana fruit sotting of apple trees. In the orchara soli management plots at Lafayette a heavy crop was borne on most trees in 19^)7. The most vigorous trees set a gooa bloom in 1938 following the heavy crop in 19o7. Vv'eaker trees were distinct biennial bearers in their response to the 1937 crop, while the .veakest trees set a light bloom in 1938 even though they core a lignt crop in 1937" . Lime Benefits the Soil "All plants need calcium to ouild up their tissues. It has long been considerea among the first 10 elements essential to the grov/th of practically all green plants. All soils contain some of it, often in the form of carbonate of lime. Soil water, holaing carbon aioxiae in solution, dissolves this carbonate of lime for reaay use \^y plants; ana yet this solubility makes lime rather eas- il:'- lost byXleaching into the subsoil or by arainage" . These state- ments are found in a new farmers' Bulletin No. 1845, "The Liming of Soils", a revision of a former publication. The benefits of lime are these: "It neutralizes acias in the soil and stimulates the proper aecomposition of organic matter, improves the physical con- aition of heavy soils, supplies calcium ana promotes bacterial act- ivity in the soil, making other elements available to growing plants ana generally increases the efficiency of manures ana fertilizers. It facilitates the proauction of green manure crops gro-Aoi for soil improvement . Some Fertilizer Facts Worth oonsiaering A reason for the graaual swing toward high graae or aouble strength fertilizers is founa in South Carolina circular No. 60 vvhich aeals vdth fertilizer ana liming practices. We read: "South Carolina farmers have been paying one million aollars an- nually for sand ana other inert materials mixea in fertilizers. Why not divert this non-proauctive expenditure into much needed lime ma- terials and make it possible to have a more diversified live-at- home system, of agriculture? The soil acidity problem in South Caro- lina is the limiting factor in determining a alversified system of agriculture. The rninimiim total plant nutrient content of mixed fer- tilizer should be around 20". 6 FArM aJML) iiOML WLM FRUIT MEtJINGb IN aMHLR^T , TiiUkbi/AY ANb ikIuAY. JULY 25-^.6.

Apijle Kosette Caused 'o'j Boron .feiiciency The accompanying sketch was made from a Mclntosii apple t'.vig from an orchard in Peru, Nevv York, which snows severe boron dericien- cy. iir. A. B. Burrell mailed us some speci- mens early in June to illustrate a symptom known as "rosette", which thus i'ar hus not been observed in Massachusetts. Growers are askea to be on tne lookout for this symptom although there is little likelihood that it will appear this season ovv'ing to the abnorm- ally heavy rainfall. Cornell Bulletin 4L8, "The Boron-Deficiency Disease of Apple," des cribes rosette as follow's: "The tufts may be either at the tips of tvdgs otherwise bare or on spurs. The inaividual leaves are awarfea, stiff, tiiick, brittle, and have smooth margins instead of tne usual notched margins. Leaves v\rith these characteristics sometimes develop without noticeable short- ening of interncdes. Kosette may develop any tiiac auring the season. At first, the leaf color is normal; but, late in the sea- son, the rosette twigs may develop incip- ient aieback or lieback. On a given s.hoot, one sometimes sees a gradual transition from normal leaves normally spaced to narrov/ dwarfed leaves and short internodes." More Evlaenco on the Effects of Lime Sulfur The recorarrienaations which havt been made "Ohis season suggesting the likelihood of severe injury from the use of lime sul- fur has been supported 'oy tests in one of the eollege orcharas. Part of tnis orchard was sprayed 'with lime sulfur in the pro- blossom sprays ana part with a milu sulfur. That part which was sprayed with lime sulfur shows serious injury in the form of dwarfed, crinkled, and scorchea leaves while the part sprayed W'ith milu sulfur shows practically no injury. The severity of the injury on the llm.e sulfur plot was aue chiefly to the unusually tenaor condition of the foliage inauceQ, by heavy rains auring the grov/ing season. Furthermore, it is interesting to note thai: 9«Hb :iua oeen satisfactorily eon- troiiea on the mi la suiiur plots by paying suecl^i c-ttention to timing and coverage. Thus, eviaence continues to accumulate in- dicating that scab can be successfully con- trolled and that lime sulfur injurj'' can be avoided by suostituting milaer forms of sul- fur. 0. C. Roberts FRUIT NOTES - July, 1940 W. H. Thies Extension Horticulturist A Successful Series of Twilight L'eetings. Slightly more than 1500 fruit growers have attended the 51 twilight or- chard ffioetings held in Liassachusetts during the past three months. This moans 3J1 average attendance of almost exactly 30. These meetings v/erc distributed as follows: Berkshire County, 1^ Franklin and Plymouth, 2 eachj Norfolk and Hamp- shire, 3 each} Bristol, 65 Essex, 8; iiiiddlesex, lOj and tJorcester, 15. F^om the standpoint of grov;ers in attendance, Essex County with an average of 55, and Wor- cester County with 33, top the list. It has been the v/riter's privilege to at- tend 25 of the 51 meetings. Sustained interest from April to July indicates the worthwhileness of this sort of get-together. Vi/'e are v/ondering which individual grov/er has the greatest number of meetings to his credit, and venture the guess that some have attended at least 10 meetings. Protecting Peaches Against X-Disease« If you have a peach orchard or are thinking of starting one, you vdll vra.nt to keep it free of X-Disease. The source of this trouble is the v/ild choke- cherry. Therefore, elirrdnate all chokecherries to a distance of 200 feet from the orchard. This can best be done by spraying the cherries v/ith a proprietary weed killer consisting of sodium chlorate and a deflagration agent (a chemical to re- duce the fire hazard) at the rate of 3/4 pound per gallon of water. You don't need high pressure, but cover the leaves thoroughly- Spraying can bo done any time the cherries arc in full loaf. How is a good time. Romcmbcr that a weed killer kills all green vegetation with vdiich it comes in contact. The leaves of sprayed cherries will die in a fev; days, but don't mov/ or cut them dovm till late fall or early spring. This gives the poison time to get to the roots and kill the whole plant. Usually the chokecherry can be distinguished from, the black or rum cherry by its much deeper and sharper serrations along the edge of the leaves. Lock sharply for sharp serrations. If 3''ou are in doubt as to v;hlch kind of cherry it is, better spray it anyway. The spraying is good insurance. If, after four or five days, the leaves haven't all died, or if after ten days or two weeks nov»- leaves appear on what looked like dead shoots, the tree v/as undoubtedly a black cherry. Chokecherries seldom recover from the sprays black cherries often do, un- less very thoroughly covered. j o Railev "THE BEST SALSSISN FOR MORE APPLES ARE GOOD APPLES."

In "New England's Prospect" (the earliest agri- cultural account of Mass.) he likewise testifies to the excellence of the native grapes "which are very bigge, both for the grape and the cluster, sweet and good." But he is not so enthusiastic about the cherries. He says, "They be much smaller than our English cherry, and if they be not fully ripe, they so furre the mouth that the tongue will cleave to tho roof and the throat wax hoarse with swallowing them. English ordering may bring them to bo an English chorrie, but yet thoy arc as valdo as tho Indians." (I'Jaybc he got a mouthful of chokcchcrrios.) The Apple Maggot Situation. Growers sometimes say that the recommended timing of maggot sprays and dusts does not seem to conform v/ith the appearance of flies in the orchard. How often v;e hear someone remark, "I saw no flies until the middle of August." There is, of course, a possibility that the grower may not have seen the flies v/hen they first appeared in his orchard, but there is one other possibility. V/e knov; that maggot flies migrate from one tree to another. Rolativcly fov/or flies omor^e in a v/cll sprayod orchard of Baldwin or other coi:miercial variety than from the soil beneath earlier varieties or beneath neglected trees on adjacent property. In other words, the problem of migrating flies is often overlooked. The sudden appearance of flies in a Mcintosh tree around the middle of August may mean that those flies caaie from a Yellow Transparent or Astrachan tree where fruit is no longer available. They may also represent flies which have com.e from a more dis- tant biennial bearing tree which was infested with maggot last season. We would not dismiss tho likelihood that miany flics emerge from the orchard soil long af- ter tho month of July, but wo would stress the absolute necessity of doing more about these other sources of infestation which so often pass unnoticed. In Massachusetts we pride ourselves on being able to hold in check a troublesome, late season pest v/ithout leaving an excessive residue on the harvest- ed fruit. This is entirely possible by follovidng the recommended spray schedule, spraying or dusting up to the last of July, along vdth proper attention to all other apple trees v;ithin 200 yards of the orchard and the prompt destruction of maggot infested drops. We therefore have avoided advising growers to spray "when you sec tho f lios" . If that wero followed literally it might moan using load arsonato aftor tho first of Scptombor. We recognize, of course, tho almost help- less onvironmont of som.o coimnorcial orchards. This only emphasizes tho nood for thorough spraying up to the last of July, and the treatment of adjacent trees, suggested above. Occasionally maggot flies may emerge too late to be reached by a spray progreun. But such an occurrence ought not to serve as a blanket alibi for all cases of maggot infestation. Shall Wo Put Away the Sprayer for the Season? V/e like to think of August 1 as the dead lino for orchard spraying in Massachusetts, although conditions may require some spraying or dusting r.ftcr that date to take cere of certain emergencies. One problem v/hich may bo en«- countered this season, judging from the fairly heavy first brood, is a severe infestation of leaf hopper around the last of August or first of Septenber. Ap- plication of a contact insecticide such as nicotine at that time has proven highly successful in combatting this insect which is responsible for not only mottled leaves but unsightly fruit at harvest time. Another em.ergency which may require later spraying is a severe infesta- tion of red mite. Ordinary soap in the form of soap flakes may be used, although a potash fish oil soap is not only effective but somewhat easier to use. This ma- terial is applied at the rate of 1^ gallons per 100= Your local dealer in spray raa.terials should bo able to supply this material. If not, details may be obtained from tho Field Station at Vfaltham or the State College in Amherst. A third use for the sprayer will be found this fall in some orc?iards in the application of the new hormone which tends to prevent Mcintosh from dropping. As suggested elsewhere in this issue this material should not be applied until the apples have actually started to drop. Growers with an apple scab problem are advised by 0. C. Boyd, Extension Pathologist, to make a raid-August application of sulfur dust to prevent infection of the fruit. Time to Begin Picking Up iilaggot Infested Drops . V/ith apple maggot flies laying eggs, the time has arrived for gathering up infested apples as one moans of controlling this pest. Every apple maggot des- troyed this sunmer v/ill mean one less fly to attack the fruit in 1941. Kiaggot in- fested apples should bo gathered up regularly at least once a week (twice a week is better) and treated in such way that the maggots are destroyed. Such fruit may be fed to live stock, made into cider, or emptied on an area which has pre- viously been saturated with waste crankcase oil. Apples of tho summer and fall season are more important from tho standpoint of maggot control than hard, ^/vinter varieties. It apparently doos littlo good to pick up drops in Soptombcr and Octo- ber unless the August drops are also givon attention A'ople Tree Survey Noars Completion. The first 400 orchard schedules in the Massachusetts apple tree survey have now been summarized. These orchards contain 238,000 trees and produced, in 1939, about 700,000 bushels of apples. Tliis represents approximately one-quarter of the commercial apple industry in Massachusetts. The variety distribution of permanent trees in these 400 orchards is as follov/S£ Mcintosh 42.1/^, Baldvdn 27.5/^, Delicious 5.2/^, Cortland 3.7/o, Graven- stein 3A%, Wealthy 3.3%, Northern Spy 3.8^, and other varieties 11>. Tliat we are gradually becoming a "one variety" section is borne out by these figures. Vi/hen the previous survey was taken iji 1925, about 25/i of our apple trees were of the Mcintosh variety and iO% were/the Baldvdn variety. Today this situation is reversed. The age distribution of trees shows 19.5/^ of the Hclntosh to be under 10 years of age and ll/-, of the Baldvdns in the same age group. In other v/ords we have barely enough young Mcintosh trees to maintain that variety and fov;or still of other varieties. A total of 1S16 schedules covering orchards of 100 trees or more had been received at the State College on July 25. Enough more schedules are expect- ed mthin a few days to bring the number up to about 1700 as compared vdth the 1754 orchard surveys in 1925. A preliminary statei.^.ent from Connecticut covering about 75/o of the or- chards in that State show that one-third of the comi'nercial crop is produced by 2.6/0 of the growers. According to the grov/ers' estimate, 20.5/a of the apples in Connecticut grade less than U. S. Ho. 1. Gardner Talks on Preventing Llclntosh Drop« F. E. Gardner of the U. S. D. A. Horticultural Station at Beltsville, Jsryland, speaking at one of the Farm and Home Week fruit meetings offered these timely suggestions to grov/ers applying the promising new hormones, napthalene acetic acid and napthalene acetamide, for preventing Mcintosh drop. 1. Dolay thG application as late as possible, beginning about the time tho apples bogin to drop. 2. Spray Vidth utmost thoroughness in order that the stons may bo covered. 3. Don't lot the fruit hang on the tree too long because that vd.ll tend to impair the storage quality. Several commercial concerns are offering these hormones for sale at the present time. Details raay be obtained from your county agricultural agent or from the State College. The price of these materials is still rather high since they are being synthesized for plant use only. Having no other use at the pres- ent timo, the cost of manufacture is necossarily high. The abovG mentioned plant hormones v/cre first used in the rooting of cuttings v/horc it was found the.t thoy tended not only to encourage rooting but to prevent the dropping of tho leaf petioles from tho stem. Experiments showed that these materials were equally effective in preventing the abscission of fruits. Five to ten parts per million are effective in preventing fruit drop. If the temperature at the time of application is high, there is an effect in 24 hours. If cool, the effect is first noticed in two or three days. On some var- ieties an application is effective for two or three weeks, although on Mcintosh the time is only 8 or 10 days and the effect terminates very abruptly. It is re- conraondod that the first half bushel or bushel bo allov/od to fall before applying. The first application can be followed by a second, if noodod, in about 7 days. Fruit has boon kept on the tree until after Christmas in experimental tests. Apples, whose stems were sprayed by means of an atomizer, leaving the rest of the tree unsprayed, stayed on almost as well as v;hen the v;hole tree v/e.s sprayed. In applying this materie.l v;ith a pov/er sprayer the application must be sufficiently thorough to insure complete coverage of the stems. More effective spraying can be done from inside the tree since meaiy of the apples are so com- pletely protected by leaves as to make thorough spraying from tho outside quite impossible. The only effect on the hormone treated fruit is e-n improved color. Im- provement in color is apparently duo noo to the hormones directly, but to tho fact that tho fruit hangs on tho tree longer. Treated apples have shovm less scald than 'chose picked earlier. But if they are allowed to hang on the tree too long they don't keep as v;ell. The absolute safety of the material from the standpoint of huxian con- suj-jption is em.phasi2ed by this authoritative statement. "If an average sized man v/ere able to eat 40,000 bushels of 8.pples at one sitting, the ai'nount of the hormone consumed might make him quite sick." Sorae SUfi:,p;estions on Siaall Fruit s_. C. M. Wood of the Sssex Coui^sty Agricultural School has kindly furnished the follov/ing notes from a Farm and Home Week talk by J. H. Clark of Nev; Jersey. Dorset, Catskill, and Pathfinder are the leading strav/berry varieties in ilevj- Jerseys the Pathfinder is resistant to red stelo disease. Soils vdth a pH reading of 4.2-5 are benefited by the use of lime for strawberry grov.dng. Raspberries vn.ll apparently stand more acid soils than strav/berrics . Readings down to pH 4.5 have shovm no ill effect, although lirao has holpod in some cases. For both strawberries and raspberries si-naller crates are being usedj the 16-quart and 12-pint are now becoming popular. It is feasible to make tvro grades of rasp- berries and strawberries v/nile picking. Lathai:! is still the best raspberry varietj'' for New Jersey. Other var- ieties are not so productive or dependable. Sunrise, which is ten days earlier th3.n Latham, is pror.iising. llulching raspberries and blueberries on the lighter, hotter soils seems practical. Precooling and treating v/ith carbon dioxide as a part of the marketing program is being investigated. Cellophane is being used on the box if the berries are in good condition.

That a worker bee, during the active season, lives only 4 to 6 weeks? There are records of a queen bee living as long as 7 years, according to F. R. Shav/ of the Department of Entomology. That most tree fruit buds are formed in June or July, 10 to 11 months before bloom v;hile strawberry buds are formed in September about 8 months before bloom? That drops of "dev/' often seen in the morning along the margins of les.ves. or at the tips, as in grasses, come from within the plant and are not caused by outside condensation? A cool night following a warm day vdth a resulting high humidity, especially v/hen conditions are favorable for intake of water through the roots may cause the excess wator to colloct as droplets instead of being trans;" ir ed. normally . Sulphur and Orchard Soil Acidity* Except where heavy applications of dusting sulphur are made over a period of years 5 Massachusetts fruit growers have little to worry about as re- gards the acidifying effect of fungicides applied for disease control. It is a well knovm fact that an application of sulphur tends to make the soil more acid, whereas an application of calcium in the form of line, makes it more alkaline. Grovdng plants require both of these elements, although calcium is required in greater amounts. Fortunately, fruit plants are fairly tolerant of acid conditions c Apple trees, for example, will thrive on soils ranging from '-quite acid to nearly alkaline (pH 4.8-pH 6.8). The crop of grass and other vegetation between the trees is a good indicator of the need for lime, better in fact than the tree it- self. Thus, if the soil becomes so acid that only acid tolerant plants will grov;, cai application of lime mil benefit the cover crop, and indirectly benefit the tree. Furthermore, it should be remembered that our soils in humid Nev/ England tend to become more acid each year by a leaching out of bcisic materials thus requiring an occasional application of lime to im.prove growing conditions. In a certain Massachusetts orchard v/hich has received about l-g- tong/A* of dusting sulphur during the past 15 years nothing but moss v/as found grov/ing under the trees because of the extreme acidity. An application of about tv/o tons of ground limestone per acre has remedied this condition. One ton of high cal- cium lime is capable of neutralizing about 640 pounds of sulphur. This makes it possible for the fruit grov/er to remedy the acid condition brought about by sul- phur applications at little expense. In a spray program involving the use of lirao sulphur, vrith its content of calcium and sulphur, there is little or no ch^^ngc in the acidity rating of the soil. And if an occasional lim.o application is made to take care of the cover crop we believe that fruit grov/ers have more important things to v;orry about thaji the possible danger of acidifying the soil through the application of sulphur fungicides on the trees. ^D:lii.-ii°iS.?.

FRUIT iJOTES October, 19^0 W. H. Thies Extension Horticulturist 108 Years Ago Speaking before the Massachusetts Horticultural Society- October 3rd, 1832, Dr. Thaddeus Y/illiaia Harris, a prominent entom- ologist of that day ssid, "Many orchards suffer from the neglect of their proprietors j the trees are permitted to remain year after year without any pains being taken to destroy the numerous and var- ious insects that infest them; old orchards especially are over- lookea, and not only the rugged trunks of the trees but even a forest of unprmied suckers around them are left to the undisturbed possession of the apple borer. Did this slove;\iy and indolent practice affect only the owner of the neglected domain v/e should have no reason for complaint; but vJien the interests of the com- munity are exposed by the harboring of such noxious insects, vvhich arinualjy issue from their places of refuge and overspread the neighboring country, when oui' best endeavors are thus frustrated, have v;e not sufficient cause for serious accusation against triose who have fostered our assailants?" This sounds like modern doc- trine and might well be expressed in soiuewhat different words by a present day entomologist. In the same talk Dr. Harris outlined the control of var- ious fruit insects. Concerning aphids he said, "The means of des- troying Aphides are readily obtained and applied. Solutions of soap and weak alkaline licuors used warm, and thrown up by a gar- den engine, are the proper remedies." The term "garden engine" is a puzzler. Those of us who supposed that spraying had its origin in the Gay Nineties are surprised to learn that an insecticide in liquid form was applied by a mechanical contrivance more than one hundred years ago. Do You Know That each normal seed which develops in a fruit, be it apple, grape or strawberry, results from fertilization by a sep- arate pollen tube and that there may be scores of these pollen tubes competing with each other for tae privilege of fertilizing a single seed embryo?

Orange growers get 22^. These figures released by the IJ. S. D. A. are accompanied by an explanation that the grower's share of the retail dollar is affected by the differences in the amount of marketing services rec^uired to get the individual cominodities from the grov^er to the consumer. That water and most, if not all;* of the mineral elements used by a v/oody plant such as ari apple tree flow upv^ard through the sapwood, v/hile carbohydrate materials manufactured in the leaves are moved through the inner bark? This helps to explain why a tree girdled by .licemay live for months because of an ade- quate water supply, although root growth fends to stop because the channel through which the carbohydrates flow, is interrupted.

England Favors Dv^arfing and Semi-dv/arf ing Stock H. B. TuKey in a recent issue of the Rural riev; Yorker makes this interesting co;iL:ient about apple grov/ing in England, "A recent visitor froui England -- a fruit grov/er vrho operates a large acreage in Sussex, reports his entire satisfaction in Eng- land v.'ith soaie of the new dwarfing and seiai-dwarfing stocks which are nov\i receiving attention in Ainerica. He reports that it would be difficult to find a coiajiercial orchard in his section where trees are grown on seedling rootstocks as they are in America. He finds that Mailing XII and XIII are very good as semi-standards, and he finds Mailing IX, II, and I highly desirable. Here's an Idea The importance of deep soils for orchards can scarcely be over emphasized. Many orchards are unprofitable because of a waterlogged condition and a resulting lack of soil aeration. If you are considering a possible orchard site, here is a test that may prove helpful. A year previous to planting, dig several holes about three feet deep in different parts of the area. V/atch these holes during the growing season, and if water is found in them after the leaves come out in the spring, or for more than a day ov two during the growing season, plant your orchard somewhere else. J. K. Shaw Apples Growers Report on Effectiveness of Hormone Reports fro;;) growers w^ho signified their intention to spray for the control of preharvest drop are coming in slowly. Many have not yet reported and perhaps some did not carry out . their intentions. Most growers reporting seem to feel that the material used was effective. This season was rather cool and Mc- intosh dropped muc?i less than in most years. Results of our own experiments are being studied. In -lost of them the material has been more or less effective. It will be somewhat difficult to determine exactly when and under what conditions sjiraying to con- trol dropping may be expected to return a profit. \/e hope to have some opinions v/hen the data have been further studied. Great- er effectiveness may be expected in a season v/hen apx_es tend to drop prematurely. J. I'v. Shaw 4 Gas Storage Experiinent rjnder Vvay One of the small cold storage rooms at the State College has been made gas tight, 191 bushels of apples have been jrat in and the room sealed ap October 11. The CO2 content is increasing and the oxygen decreasing as might be expected. The temperature is being held around ^0° F. The desired gas mixture of 2% oxygon^ 5;; carbon dioxide^ and 93a nitrogen should be reached in due time. J. K. Shaw Retarding the Ripening of Strawberries According to a recent Michigan publication the following factors aided in retarding the season oi' maturity of the Diinlop strawberry: (l) A north slope retarded fruit maturity nine days as compared with a south slope of the same soil type. (2) A clay loam soil caused a four day retardation over sandy loam on a north slope. (s) Delay in removing the mulch had little effect on the date of first picking but retarded the end of the picking season four to five days. (.4) As compared with no mulch, the fact that a bed had been winter mulched retarded the date of first picking 3 to -4 days. The dates of largest pickings and the dates of the last pickings were retarded from 7 to 10 days. .Moreover, the use of winter mulch increased the total yield by about 50)1 as compared with the plots that received no winter mulch. (With the straw- berry mulching season at hand, this last stateinent deserves care- ful attention) A. P. Fi'ench Western Growers Practice Hand Pollination An indication oi the grov/th of hand pollination in the State of Washington is provided in a statement by a Wenatchee norticulturist in a recent issue of Better Fruit. A ^25,000. industry was created last season by those who gather, sell, and apply with camel's hair brushes, the apple pollen. Thousands of acres are now being pollinated in. that way. The writer predicts that the practice is barely in its infancy. He believes it pos- sible to control the size of the crop in many orchards by this method, eliminating the necessity of thinning entirely. Skin Lotion for Cherries In a recent issue of The Furrov/ we read, "Cracking of sweet cherries, because of rains at ripening time, often causes losses of from twenty to eighty percent of the crop. Experiments are being made with cdcium. sprays to prevent such losses, for calcium is capable of reducing the permeability of plant cells to water. Removal of the calcium residue before packing the fruit is a problem as yet misolved. WANTED — Pomological Puzzles Dui'ing the past few weeks our appetj.te for baffling prob- lems has been whetted by the solution of a cover crop puzzle in eastern Massachusetts v/hich was brought to the attention of the State College. In this particular orchard the grass beneath the trees \vas almost entirely brovm even, though no caustic fertilizers had been applied. An unusual soil type plus an mvasual spray pro- grarfl suggested the possibility of aluminum toxicity. A series of soil samples being studied by Professor Everson of the Department of Agronomy bear out this supposition. A more detailed report will appear in a later issue of Fi'uit Notes. ..lany of the problems in agriculture are not susceptible to an imi.iediate solution. Snap judgments are of little value ijui- less the problem conforms to a familiar pattern. The unusual de- serves as much study as time and facilities will permit. In this connection the v/riter invites Massachusetts fruit grov.'ers to sub- mit unusual situations for the careful consideration of State College v/orkers. The ansv/er will not always be forthcoming but a clue is more than likely available. With some knov>/ledge of funda- mentals as a starts other available resources include the literature on the subject and the facilities of co-v.;orkers in the State Col- lege laboratories. Probl<\i3 in this class may involve fertilizers, spray materials, plant behavior of an miusual nature, or anything else along production lines of an unusual nature. Attention will be given to such puzsles insofar as time will permit and they will receive attention in the order in \'.'hich they are received. Grass Land Agi'iculture The Agricultural Conservation Program tends to focus at- tention on the value of grass. In Massachusetts we pride ourselves on growing an abundance of this fundaiiiental crop. The difficulty among fruit growers is found in a faulty disti'ibuticn. LovV land areas v/here the soil is fertile and moist produce a ranlc stand of grass, v.'hile upland areas subject to erosion and drouth are but sparsely cov.red. Hence the need for a soil building practice on the poorer soil and a bringing m of mulch .aaterial from the low land. V.lien v;e think of "grass land agriculture" we are not think- ing of a return to extensive pastoral farxming but rather of an ad- vance tov;ard a high type of intensive farming. It does not pre- sume that all land is to become and remain permanently as grass land although much of it may, particularly the land not suited for tilling. V.Tiere conditions permit this type of agriculture pre- sumes a periodic breaking of grass lend in preparation for other crops .

Maybe the cow in question got more than her share. List of Agricultural ExperLnent Stations Any reader of Fruit hotes desiring a list of the Agri- cultural Experiment Stations m the United States with addresses may obtain the same by dropping a postcard to the Department of Pomology. Many of these stations send publications free of charge while others make a small charge for out oT state requests. This offer of a list of stations is prompted by an occasional inquiry from growers for the correct adaress of a distant i'.gricultural Ex- periment Station. Warm and Cold Soils In a recent issue of the American Fruit Grower L. D. Bavei' of Ohio State University says, "Soils receive all of their heat energy from the sim. Dark-colored soils absorb more of this energy than light colored ones. Therefore, organic matter in the immediate surface tends to darken the soil and increase its abil- ity to absorb heat. The presence of v/ater in soils, however, leads to a cold soil, especially in the early spring. It takes about four times more heat to warm up a pound of water to a given temperature than to warm up a pound of dry soil. ConseL^uently, it is essential to drain soils in order to have warm soils. Those soils with a low content of large pores are usually v/et and cold in the spring." V«et soils are not oniy cold but also lacking in aeration. It is a well linovm fact that plant roots will not function if the oxygen content of the soil air falls below a critical point. The failure of roots under these conditions is due not so aiuch to ex- cess water as to insuif ic lent oxygen. Plants will grow with roots in water if the water contains oxygen. Without oxygen they are of no use whatever to the tree. This suggests why fruit trees do so poorly on a v/aterlogged soil. Bakery Experiments with Apple Bread A leading baicery m Seattle/i/ashington, has been using apple flour in an experihiental v/ay but as yet has not met with much success. This bf.kery reports that the acid reaction in the dough made it impossible to put enough of the flour in the bread to give it a distinct apple flavor. r*^ FRUIT ilOTES - ]Iove:aber, 1940 U. a. Tales Extension ilcrticulturist Do You- Know That the ifassachusetts Horticultural Society v;as or- gani::ed ..larch 17, 1829? Today this organization is said to possess the finest and most extensive horticultural library in the world. That the position of the seed in stone fruits is the reverse of that in apples and pears? In other words, the pointed tip of a peach pit points av.ay from the stem while the tip of an apple seed points in the opposite direction. That apple pectin coir.bined with nicotine to form nico- tine pectinate is being used experimentally in apple pest control? Perhaps we'll see future apple grov/ers using their culls, if any, in the manufacture of a ''cull preventing" spray. That the grovvth rate of a young apple may be sufficiently rapid around the first of June to result in a doubling of the surface area in two days? This fact has an important bearing on the control of pluai curculio since a protective film of spray ma- terial is very soon outgrov/n.

Apple Survey Cummary Hears Completion ViThat changes have occurred in Massachusetts apple or- chards since 1925? How imniy trees do v/e now have oi sac':: varie-ty and of each age group in our ccmmercial orchards? These and other questions will be answered by the apple survey suminary which •.■.■ill be available for discussion in v.-inter meetings. Records froai about 170j orchards of 100 trees or more are included. In the writer's opinion, the individual grower may profitably consider his ov;n set-up in relation to the statewide situation, j-iverages and to- tals are interesting although of little real value. Vrnat the in- dividual grov^er does to reorganize .his enterpirise in the direction ox greater efficiency is of maximum importance. Here' s an Idea Much as we dislike to luake drastic pr'uning cuts in a young fruit tree, it is often the ersiest ^./ay of getting the de- sired framework. For example, let's imagine a vigorous three-year- old apple tree with a good framework except for one side li.nb vvhich is growing faster than the leader. It sho'ws a terminal grov.'th of I'D inches, vriiile the leader shows only twelve. Obviously, if that rate of growth continues, the framework of the tree will be upset and we are likely Ic have two competing leaders.. Experience has showii that a li.iib 01 this kind is diffi- cult to dv;arf. Even if cut back 50f: it will generally assert it- self enough to require further cutting a year later. But if v.'e reuove this limb instead of heading it back, some oi' the nutrients will be diverted into other brancnes and balsnce v.^ii be restored. In pruning young trees, it is always advisable to observe the ter- iiiinal growth made by the different branches and by the leader, in order that a balanced framework of properly subordim.ted brancnes may be maintained. So.ae Apple Oddities Have you discovered any i'reaks of nature in your orchard this fall? I'" so, the details v>:ill be welcomed for publicction in Eruit riotes. As examples of the way in which nature occasionally outdoes herself, wo submit; recent observations as follo\,s; (l) A northern Sjjy apple which appeared to have been stretched laterally to such an extent that the calyx v/as tv;o inches across by t.ctual ineasureinexit . The apple in that direction had a diaaeter of 4-;i inches. (2) A three-year-old Jclntosh tree bearing a long ste.n.ued, attractively colored "apple'* about three-^^uarters oi an inch in diameter witli three leaves grov;ing fro..i it v;herG the ste;a v.as attached. These leaves v;ere in the sauae position as the leaves on a quince. This "apple" v/as seedless find evidently developed irorj a late blossom. (3) A iiclntosh branch with at least half a peck of apples every one of which shov'ed distinct v,-atcr core, v;hile the fruit on the rest of the tree was normal. This latter freak was reported by an orchardist in Essex County. ifc-i-ioth Delicious Apples from the Northwest Delicious apples of almost unbelievable size are now on displiiy in stores in Eastern dassachusetts . In a Brighton grocery our eyes popped open as Vve viewed these giants pro;.iinently displayed alongside some of our .'.iclntosh. The latter looked like crabapples in comparison. Thinking that we might have gotten on tne wrong glasses by mistake, \:c v/eighed a fev/ specimens. Si:-: picked up at random weighed 5 3/4 lbs., while t\»'o others weighed 15 ounces each. One of these speciiaens jiiccsured slightly more than four inches in diameter. Eastern growers may learn a lesson froin these ii.'iported apples. Every effort uiust of course be iaade to insure a ininimum amount of bruising. If a 4-in. Delicious can be shipped 3,000 miles and arrive in the consumer's hands m good condition, we should be able to trinsfer our mclntosh from the tree to the con- sumer next door, v/ith most of the skin intact. Cooperation be- tween grov;er and handler is necessary. Ample Supply of Apnles in Stora^-e The .aovc.iient 01 apples into storage during October, 1V4J^ totalled 21, 941 > 000 bushels as compared viith 20,203,000 during October, 1939 and the five yccr average of 21,415,000 bushels. These figures are taken from the November 19 Special Apple Jarkct Report prepared by V/. E. Piper = On IJovember 1, 1940 tot;..l storage holdings in the United States amouiited to 30,331,000 busiicls as compared with 30,307,000 bushels on ^iovember 1, 1939. Storage holdings in New York State are f bout 1,500, 00 J bushels loss than, last year while the storage holdings in ..'ashington <'.re nore than a 1,000,000 bushels above last year. Potash Jnder a ..lulch Recent experiments throw further light on the fi.vorable response of fruit plants to a heavy mulch. Besides the improved moisture relations and a better supply of nitrt.tes v.'e can nov: attribute to the mulch a better supply 01 readily available pot- ash. G. 1.1. Dai''row and J. P. Idagness find that raspberry picnts respond v;ell unuer ::iulch treatiiient at Beltsville, ..iaryland. i^uct- Ing from an Aaerican Fruit Grower article, --"Lcthara plants were uiuiched v/ith rye strc.v; at the rate of aoout eight tons per acre. In addition, nitrate of soda Vi'as applied in April and July to the mulched and control cultivated rov;s . At a depth of tv;o inches, soil te/aperatures were higher in sumuer and lower in winter under tillage than under mulch. The total cane growth \;as much grec tcr in the jaulched row than in the cultivated. Yields in 1938 v/ore five times as large in the mulched as in the cultivated block, but no significant differences vrere established in berry size. Deter- minations of the potash of leaves collected in the fall of 1933 from mulched and cultivated plants :^:ho\ved <;.39 and .S6f' respectively. If potash is applied to the surface of the soil it may soon beco.ae locked up by cheiaical reaction into an unavailable form. "This suggests," according to H. 3. Tiokey writing in the Rural i\lev; Yorker, ''tr.it if potash is put deep into the soil, say 16 or 13 inches, it v.ill be d.'' aced in the active absorbing zone of the tree roots in most Eastern orchard soils ana also below the zone in v.iiich potassium is fixed by t.lternc te \;etting and drying. It's lateral movement should then be ample for supplying the needs of the tree." The locking up of potash applied to the surface of the soil may be one reason for the common lack of response to such applications, .'vt the same time the liberal a.aounts of available potash found rmder heavy mulch offers further justification for heavier mulching in our sod orchards.

This disease was found in three Utah counties in 1939 and two more were added to the list in 1940 • Some orchards are reported to be very heavily infected. One six year old orchard was so heavily infected that the ovmer pulled all tiie trees. It is interesting to note that although this disease v/as first reported from Connecticut in 1933, it has nov; been found as far west as Utah. J. S. Bailey Virus DiseaS'is of Peaches £. A. Walker of th.e University of Maryland emphasizes the importance of virus diseases of peaches when he lists the following v/hich are prevalent in one or more sections o'^ the country: peach yellows, little peach, red suture, resetted mosaic, green mosaic, several line pattern diseases, phony peach, peach rosette, peach mosaic (v/ith three or more strains of virus), peach ring spot, asteroid spot, peach calico, Winter's peach mosaic l3af casting yellows, and yellow-red-virosis or "X" disease. Prob- ably the last is the most dangerous one for Massachusetts. Many of the others, fortunately, are not a problem here.

J. Keinicke and his associates have produced cork in apples experimentally. A normal Northern Spy tree that had alvmys borne perfect apples was subjected to excessive irrigation from August 25 to November 14 in 1938, and April 15 to August 11 in 1939. By mid-June, 1939, the yoimfj fruits shovifed early symptoms of surface cork as well as internal cork. Over one-half of the branches bore corky fruit. Much of the foliage also was abnormal. Presiimably, there were plenty of nutrients in the soil, but, with the oxygon content abnormally low so that the tree roots could not function properly, the nutrients were unavailable. Other investigations have shov/n that there is less ash (minerals taken up by the plant) in plants grovm under low levels of oxygen in the rooting medium. In fact, lack of aeration in a soil may interfere more v/ith the absorption of po- tassium and some other elements than it does with oiie absorption of boron. Normally, cork is associated v/ith sandy or shallow soils, especially in a dry year and when the nitrogen and calcium level.s are relatively high. L. Southwick The Soil Moisture Situation As this is being written, a total of 17 3/4 inches of snow has been recorded this v/ints-r in Amlierst. Most of it has melted gradually, and since the groi^nd v/as only slightly frozen the penetration has been fairly good. Otherwise, we might begin the 1941 season with a real moisture shortage in the soil, as shovm by these figures. The latter part of the summer of 1940 was very dry with a total rainfall in August, September and Octo- ber of 4' 13 inches. The normal rainfall for this period is 11.61 inches, the normal for September alone being 4-24 inches. On November 1 the subsoil was unusually dry, as evidenced by excava- tions in Amherst at that time. The month of November brought 6.31 inches of rain. If this had fallen on frozen ground and found its v/ay into brooks and rivers, it is easy to see the be- ginning of a real soil jnoisture shortage. A Tip from an Old Timer Grant Hitcliings, a pioneer fruit grower of Nev; York State, makes this statement about planting a.n apple orchard, "Large sec- tions of Hew York soils have been depleted of plant food. On soils of this type it is much better to plant 40 x AO or even 50 x 50 feet and not intercrop ^f;ith regular farm crops, but on the con- trary seed dovm and use whatever grows as a mulch to restore humus to the soil, v/hich will build up fertility. Using fillers and then cutting out, in the long run, does i.ot i-'ay." Here's an Idea This one has to do with the reason for suckers or v/ater sprouts in a fruit tree. Only a small proportion of the potential grov/ing points in a woody plant ever develop. Grov/th possibili- ties are said to exist in the axil of every bud scale. These "adventitious buds" lie dormant in the tissues indefinitely, bursting into grov/th only \;hen normal growing points are des- -3- troyed. A striiiing example of this is sometimes seen where a tree, such as a xilllov;, is cut off a few feet from the ground. Obscure buds just below the point of cutting suddenly find an opportunity for grov/th, which was denied them so long as normal growth channels v/ere open. A whorl of vigorous sprouts is the result. In an apple tree, sprouts commonly appear along the branches after a cold winter bec:.uso the conducting channels to many of the normal buds have been disrupted. Here the adventi- tious buds provide a growth outlet. Tree growrth is literally shunted into nev; channels v/hen normal channels fail. This is Nature's way of meeting an emergency^ a kind of insurance against disaster. The writer recalls seeing an orchard which bore unmis- takable evidence that a previous primer v/as intent upon elimin- ating all upright growing branches. Every upright growth had been removed and the following season there were at least twice as many growing in the same direction. Young vigorous limbs having efficient connections v/ith the root system can scarcely be removed without calling into activity other potential growing points, advantageously situated. The larger and more vigorous the limb removed, the more likely v;ill otherwise dormant growing points assume an active role, numerous suckers or v/ater sprouts following the pruning operation always indicate the removal of relatively vigorous branches. And as most growers are well aware, removal of all sucker growth in a tree is usuallj^ followed by a prompt replacement, if not a multiplication. V/e cannot correct the mistake of faulty pruning by more pruning of the same kind. In a young tree it is obvious that we should prune only enough to eliminate \/eak crotches and to maintain a balance be- tween the leader and the side branches. Fewer sprouts will ap- pear if corrective cuts are made early. In older trees there should be little need for the corrective type of pruning. It is wasteful of time and profits to make over the framev/ork of a tree after it reaches bearing age. In bearing trees we sare interested in getting rid of the older, submerged, and often drooping parts of branches. Cuts of this kind may be made without encouraging sprout growth. It isn't the size of the pile of prunings that determines the number of sprouts. It's the kind of growth v,'e've left on the tree. If we remove the right branch'is in a bearing tree, relatively few sprouts will appear. Do You I-Cnov'/ ?n That "The Best Salesmen for More Apples ere Good Apples? That it takes about 10 inclies of snow, on the average, to equal one inch of rainfall? That there may be as many as 30,000,000 bacteria in a single gram of soil?

The period of emergence in Connecticut in 194-0 was 55 days, June 23 to Aug. 22. Last Call for Apple Show ?]zhibits Entries for the I.I.F.G.A. Apple Show to be staged in Wor- cester, Jan. 8-10 are coming in very slowly. Not more than half enough fruit is in sight for a good show. The time is short. Let's make the show a credit to the apple industry. If you've mislaid the original announcement with list of classes, full de- tails may be obtained from Secretary V', R. Cole. Apple Committee will Confer in V/ashington January 6 & 7 The national Apple Planning Committee, of which John Chandler of Sterling Junction is a member, and a limited number of Extension representatives v/ill meet in Washington, January 6 and 7 to consider matters of interest to the apple industry, including steps v;hich may be taken in connection v.ith tiie 194-1 crop. Feeding Cull Apples to Dairy Cows This is the title of a talk to be given by J. G. Archi- bald of the State College at the afternoon session of fruit growers in Y/orcester, Thursday, January 9. This tali-; will be of interest to fruit growers and dairymen alike. Dairy cows provide an excellent local r^iarket for low grade fruit. Jelly Samples Given "Blindfold Test." Seven different kinds of unlabelled fruit jelly, mostly plum, made by Mrs. F. A. V'/augh, were sampled and rated by I4. mem- bers of the State College Staff a fev; days ago. Three of the jellies were made from Icnovm varieties of plums, — Burbank, Santa Rosa, and American Mirabelle. Two were of seedlings being tested in the College Orchard. The other two v^ere Beach Plum and a Choke Cherry-Apple combination. Strangely enough, one of the seedling varieties (BB7), not deemed worthy of a variety name and on the verge of being discarded, v/as voted best. Five in- dividuals placed it 1st and four others 2nd. The Buroank jelly took 2nd place. This test seems to suggest that certain fruits may possess real merit from a jelly standpoint even though they are quite worthless to eat out of hand. The Beach Plum, which happened to rate 3rd with the above testers, is a good illus- tration. Fruit of the Flowering Quince In recent weeks three S'eparate inquiries have been re- ceived concerning the usefulness^ if any, of tiie fruit occasion- all;,- produced on the I'lowering or Japanese Quince. The ansv/er seems to be "a limited use in combination v/ith another fruit such as apple in the ratio of perhaps one to five, for jelly making." This fruit is extremely acid and like the quince, has a dis- tinctive flavor. Only the flesh should bo used, since the por- tion around the core possesses a material similcj? in nature to the gummy exudate of a peach tree v'hich would make the jelly very "stringy." This fact is well demonstrated by a concern v/hich, according to C. R. Fellers of the Department of Horticul- tural Manufactures, processed v/hole quinces only to find that the texture of the product was anything but desirable. Thiz material, so objectionable in jelly, has been extracted in Europe for the manufacture of a hair ^j'^ooming preparation designed to conquer unruly locks. Defense Program Kits Peddler Trade In the December 27 Special Market Report, V\f. 3. Piper makes this interesting comment: "The emergency defense program and the resulting dems^nd for workers at army camps is having an indirect effect on the market outlet for cheap apples. Quite a number of peddlers have abandoned their fruit distributing activi- ties for the time being and have taken jobs on camp work. This has reduced the number of peddlei- buyers. Presumably some of this business is being taken over by increased distribution through stores, etc., but nevertheless there are fewer buyers and therefore less competition among this class of trade for low priced fruit." New Use for Hormone Spray t" ^ terial Quoting from the December 15 Clip Sheet of the U.S.D.A., "Christmas holly tliat is shatter-proof - vd.th leaves and berries that stick tight in treaisit and last longer in vrreaths and spraj'-s is possible novj as the result of U.S.D.A. studies of 'grov/th- regulating' chemicals The scientists had previously dis- covered tliat growth substances applied while holly is in bloom cause it to set the red berries without pollination. This proved a practical aid to greenhouse men growing small holly pla.nts in pots for the Christmas trade." Thus v;e see a brand new use for a material now being used in mailing Mcintosh apples stick on the tree.

FRUIT NOTES - January 1941 W. K. Thies Extension Horticulturist Changes in Eating Habits in Past 15 Years The follov;ing tabulation^ shoiving changes in the per c: pita consumption of various foods, is quoted from the January- issue 01 "Food Marketing in Nev/ England'': Av e . Lbs . Av Q . Lbs . Percent C. 1920-24- 1934-37 Vegetables 155 169 +25f.

From a health stand- point this is. an encouraging report. In terms of our northern grovm fruits, hov/ever, it has little significance since the increase merely reflects a larger consumption of imported fruits and fruit juices including the orange, grapefruit and pineapple. Vitc .mins in Ic7 Fruits . Fellers of the Department of Horticultural Manu- factures has prepared for readers of Fruit Notes this sunu-nary of a much discussed subject.) The apparent food value of fruits is often deceiving. Based on a chemical analysis v/e see notiiing particulrrly out- standing. A Mcintosh apple, for example, gives: percent Moisture Total solids (mainly sugar) Pectin Malic acid Ash (minerals) Protein Fat and Wax Calories per pound 8/ 16.0 0, 0, 0, 0, 0. 35 5 3 3 4 290.0 (same as milk) Yet the apple, and most fruits are potent factors in t'ne conservation of our health. Fruits are appetizing, good for tlie teeth and digestive tract, are somsv/hat laxative and due to the pectin (uronic acid) content, act as clearing and detoxifying agents in the intestinal tract. V/hile not high in amount, the ) minerals present such as iron^ manganese, phosphorus, calcium, and potassium are fully utilised by the body ai:id aid materially in regulating glandular functions. The sugar is iniriiediately assimilr^.ted and by eating fresh fruits v/e get a "lift" and renewed energy to do work. Fruits 3 re normally good sources of vitamin C (ascorbic acid), the anti-scurvy vitamin. Since the body stores no vita- min C froui day to day, it becomes necessary to eat fruit every day to constantly replenish the supply. Sore teeth and Joints, capillary fragility, lack of appetite and "spring" fever are often due to low vitamin C intake. The greatest danger is in the late winter and spring when fresh fruits and vegetables are scarcest. Apples, potatoes, carrots, etc., lose much of their vitamin C during storage for five or more months. Vitamin A, the anti-inf ectivo and night blindness vitamin is present in the form of carotene in most apples and fruits in small amounts. Peaches, pineapples, and oranges are highest in vitamin A. Best sources are liver, yellov; and green vegetables, milk and eggs. Similarly vitamin B or thiamin, the antineuritic vitamin, as well as the vitamin G complex (riboflavin, pantothenic acid and nicotinic acid) are present only sparingly in most fruits. Vegetables and cereals are good sources of these vitamins. Vitamin D, the sunshine or anti-rickets vitamin, is not present in either fruits or vegetables. Thiis, in concliasion, fruits are used primarily for their vitamin C content. Hlspecially high in this vitamin are straw- berries, citrus fruits, blueberries, cranberries, pineapple and tomatoes. Apples are variable in their content of vitamin C but you can usually consider apples about one-third to one-half the value of oranges or grapefruit. Apple cider contains very little vitamin C v;hile canned citrus fruits and juices retain large amounts. Fruits contain small, yet significant quantities of vitamins A and E but cannot be considered primary sources of these vitamdns . After all, vre eat fruits for their zest, attractiveness and flavor. They v;het the appetite, are mildly lajiative and aid digestion. And nov; since their usefulness as the chief carriers of vitamin C has been recognized, we eat fruits v/ith a sense of duty as v/ell as one of pleasure. Food of Farm Families According to the Outlook for Farm Family Living "recent studies indicate that fewer than half of our non-relief farm families have nutritionally adequate diets, - diets that provide a generous margin of safety over minimum requirements. Fully a fourth of these families c;re believed to have diets that are definitely below the Scifety line." Hov; far short of good nutri- tion does farm family food consumption actually fall? Studies of a large group of non-relief farm families reveal the following deficits. Tlie percentage figures indicate how far average per capita consumption falls below that of farm groups whose diets are considered adequate. Milk (and its eauivalent in cheese) . . . 25?^ Butter .* 15^2 3ggs 30?o Tomatoes ;, citrus fruit ......,,.. 55^0 Leafy, green, yellow vegetables 80^ Meats and poultry .....,.,.. 10^ These farm families could themselves be a market for many of our surplus acres. The increase in foods needed to provide for all of our 31,000,000 farm people, diets as good as those now enjoyed by the well fed v/ould aggregate in a year: 510 million gallons of milk 95 million pounds of butter 215 million dozen eggs 990 million pounds of tomatoes, citrus fruit 2,500 million pounds of leafy, green, yellow vegetables 370 million pounds of meat and poultry (dressed weight) (The omission of apples, cranberries, etc., from this list lends a citrus flavor to the analysis. Maybe it can be shovm that the apple bowl in so;iie of our rural homes also needs refill- ing.) Do You Know That apples v'ere grovm on Governor's Island in Boston Har- bor as early as 1639? That an occasional grapevine produces only starainate or "male" blossoms? With no normal or perfect blossoms such a vine is, of course, incapable of bearing fruit. That the individual sections in a blackberry or raspberry are very similar xn structure to a miniature cherry or plum? The latter fruits are sometimes celled "drupes" and the above ruen- tioned sections "drupelets?" The botanical relationship between these fruits is surprisingly close in spite of their dissimilar appearance. That the state of Oregon produced more pears than apples in 1940? The yields vrere 4,/;i8,000 and 3,160,000 bushels, re- spectively. Pear production in V/ashington in 19.40 amounted to 6,600,000 bushels. That a cherry tree has produced as many as 1520 pounds of fruit in l. single season. That's the 1940 record of a tree ovmed by a grov, er in V/enatcliee, Washington. He says, "I don't -A- knov/ whether it's the biggest tree in the country or not, but I clo Icnov; it has produced more than 1^,000 pounds of fruit every year for the le.st ten years. That more than half of the 33;, 000, 000 bushels of apples in cold storage in the U. S. on December 1 v/ere of three varietj.es, - Vi'inesap, Delicious and Yellow Nev'tovm? The Winesaps alone amounted to 8,217,000 bushels. Mcintosh held fourth place with 2,940,000 bushels and Baldwins eighth place with 1,507,000 bushels. Delicious is the onl^'' variety stored in quantity in all of the apple growing sections of the United States. That the per capita consumption of fruits in the U. S. in- creased 5'^c between 1920 and 1935 while the per capita consumption of potatoes decreased 12/b? During the same period vegetables in- creased 25^,^ while lean meats snd fish decree sed 9% and cereal products lli.%. That only one county in Massachusetts^ Hampden, has a larg- er percentage of non-bearing apple trees today than it had in 1925? In 1925, about J^Gfo of the apple trees in commercial orchards in the state \:ore under 10 years of age. In I94.O, only 16^ were in that class. That apples, pears and quinces are "fleshy accessory fruits, made up of a f ive-carpeled ovary, with cartilaginous endocarp and fleshy exocarp, united with a fleshy floral tube or disk consisting of the fused bases of the sepals, petals, and stamens?" (But in spite of this complicated anatomy, they're not onl^'- harmless but edible and delectable.) L. Southv/ick. THAT TH2 B3ST SALSSMSN FOR MORS APPL3G AR3 GOOD APPLSS?

Beginning v;ith this issue, Voluiae and Kunber v;ill be indicated. The February issue becomes Volume 5, l-umber 2. V/ith a fevr exceptions, back issues of Fruit Jlotes ere not avail- able. Soil Temperatures V.Taat effect does mulching a tree have on soil teraperature? To ansv/er this question tv/o soil thermographs were set up under tr/o Mcintosh trees in the Clark Orchard v..t the State College, one tree under sod, the other mulched v;ith hay. The thermographs were arranged so as to measure the temperature one foot below the soil surface. During last spring the soil under the mulch v/armed up quite a bit more slowly than that under sod. The temperature under sod v/as usually three to four degrees higher than ti:at under the mulch. During last fall the soil under the mulch cool-'^d off a little more slowly, but the difference in temperature betv.'een mulch and sod v.-as not so great as in the spring, usually not more than one or two degrees. On January ;-0 the soil temperatures beneath the two trees were aluost identical, 37° P"., the lowest of the year. Notice that the soil temperature at a depth of 12 inches had n.ot yet reached the freezing point in spite of the fact that the air tem- perature has been belov/ zero on three occasions. The lowest air temperature occurred on December L vrhen it dropped to 12° below zero. J. S. Bailey. A Note on ControJ.led Atmosphere Storage The small room in the apple storage at Massachusetts State College which supposedly was made "gas-tight" last fall, evidently is not tight enough. Although the carbon dioxide lias been kept below 6 percent by intermittent "scrubbing," the oxygen content has been reduced through respiration of the apples to only 13 percent. This is far above the 2 percent level that is supposed to be ideal for successful late storage of Mcintosh. In short, in the present atmosphere (13'^ oxygen, 5% carbon dioxide, and 82^ nitrogen) the apples are ripening too fast. Tv/o clues which help to explain the failure of tliis room to behave as expected are these. There probably is a leak (or leaks) permitting outside aj.r to enter thereby/ automatically maintaining the relatively high oxygen level. In our experiments witii small, tight containers, the apples have exhausted the oxj'gen within 10 days. The second clue concerns the capacity of the room in relation to the amount of fruit therein. \Tnereas such a room should be filled to capacity, in this case it is less than two-thirds full. This may account in part for the unexpected re- sults to date. J. K. Shaw. The Apple Storage Situation If we could build a horse-high, pig-tight, bull-strong fence aro\ind the Nev; England marketing area and keep all that -6- outlet for apple grov/ers in the I\iev-.' England area, we would be, as the boys say, "Sitting pretty." This cannot be done, sc what? There is a very large volume of apples in storage in other ar?cs. '<.'l:en the ov.Tiers of these large lots start to move them, they will move . Mew England Cold Storage (Bushels) : Jan. 1, 1941 - 1,035,000 (503,000 Mc's Jan. 1, 1940 - 1,139,000 (740,000 Mc ' s , Jan. 1, 1939 - 557,000 (279,000 Mc's.) Total U. S. Cold Storage, estimated (Bushels): 1941 - 128,400,000 1940 - 26,198,000 1939 - 26,566,000 W. ^. has 10>t less than in '40. U. S. has 9% more than in 'ZO. The present situation is v;orth thinking about; and maybe worth doing something about! W. R. Cole. Rabbit Injury in Young Orchards Supposedly, frui'': growers eliminated mice from their or- chards last fall, but wjiat about rabbits? Rabbit injury to fruit trees occurs more coi;aaonly than is generally believed, especial- ly in the caso of nursery stock or small trees set in an orchard near a rabbit cover. Already, preliminary forays have been made on some of our nursery trees at M. S. C. The rabbit has the very obnoxious habit of "biting off more th^n it c;.n chew," Thus, with nursery trees, one rabbit may cut down many trees without so much as nibbling on the cut portion. For newly set orchard trees, high wire guards should suffice. Some repellants such as sulfurized linseed oil end a resin-fish oil-copper soap mixture have been tried with variable results. A sure cure is a well- aimed shotgun. Probably only a few- gro\;ers will encoimter serious trouble from rabbits, but it is well to keep on the lookout. L. Southwick. The Tree Removal Program This year for the first time the Agricultural Conservation Progrc.m offers payment for the "Removal of Diseased or Uneconomic Apple Trees." Practice K'o. I4 of the 1941 Program reads: "With prior approval of the couiity committee, the removal of diseased or un- economic permanent live apple trees, the major portion of whose fruit is of inferior quality. Land from which the trees have been removed shall not be used during the 1941 program year. Payment will not be made for the removal of trees less than 5 inches in diameter or for the removal of filler or semi-permanent trees, i'jot more than $15 P"?!" acre may be earned under this prac- tice. Rate of payment: Trees 5 to 12" in diam.- 3Cv^'3 over 12"-50(^. Tills new provision offers another incentive for the re- moval of apple trees v'hich liave outlived their usefulness. Many such trees are not only vjorthless in themselves due to their present state of neglect but are also a menace to nearby orciiards. Poultrymen and dairymen as \.'ell as fruit growers shoiild consider this new practice as one means of obtaining the full farm allow- ance.

FRUIT flOTSS - February, 1941 V^. H. Thies Extension Horticulturist Spacing of Strawberry Rimners In the past few years considerable atter:;tion has been given to the value of spacing runner plants. Reports from sec- tions of the country having longer growing seasons ;, hotter sum- mers and less rainfall than ours, have shov.n substantial in- creases in yield when the rimner plants were spaced. For example, Maryland has reported increases in yield of from 30 to 60^ for 7-inch runner spacing as compared \.'ith a matted rov' of the same v;idth. The results of our limited tests of these two systems at Amherst do not show such great advantages from spacing. The 5-year average increase in production of the 7-inch spaced vovj over the matted row ranges from 0 to 20$o, depending upon the variety. Hov;ard 17 and Borsett have consistently yielded better when spaced. Fairfax shows a slight gain for spacing while Catskiil in tv;o of the five years has produced more under a matted row than a spaced row system. The highest yield we have ever obtained from Catskiil v/as from the matted row system in 1940 v/hen it yielded at the rate of about 14,000 quarts per acre. It is possible that spacing may be of greater value on soils of lov/ fertility tlian on those whicii have an abundance of humus and fertility. ^_^ P^ ^.^^^^j^ Germination of Apole Pollen Tlie germination of the pollen of 134 varieties of apples has been tested at Cornell University. Among the var- ieties that rated highest (over 60fo germination) were the fol- lov;lng : Delicious northwestern Greening Rome hubbardston Oldenburg Tolman Northern Spy Opalescent V'/agener Red Spy Red Astrachan Vv'olf River Varieties rated as poor (less tlian 10;;;' germination) were all so-called triploid varieties, as follows: Arkansas (Mammoth IJlack Tv;ig) Fall Pippin Stark Arkansas Black Gravenstein Stayman Baldwin King Turley Blenheim R. I. Greening Fallawater Roxbur^'" Russet Pollen germination of otlier varieties was intermediate. Mcintosh pollen germinated ■.■ell, although this variety did not make the "over 60^ '^ class. j. k. shaw Phosphorus Moves Slowly in the Soil It is hnowi that nitrates move freely in the soil for V considerable distances. Experiments at the Ohio Station, hov/- ever, shov; that \,'hen potash and superphosphate ivere placed in holes IS inches deep and 1 inch in diameter, the potash moved out 6-9 inches while phosphorus moved only an inch or two in three years. This suggests why it is difficult to get phosphorus fertilizers into the tree. In California it was found that plac- ing 10 Its. treh] <=; superphosphate in the planting hole greatly im- proveti the f;rowth of nev/ly set trees on a phorpiiorus deficient soil. It has not been shovm that Massachusetts soils are suf- ficiently low in phosphorus to interfere with the growth of fruit trees. j. K. Shaw A Kote on Peach Prospects The danger of fruit bud killing in peaches is nearlj^ past and there probably remain in most peach orchards, enough live buds for a satisfactory crop. Studies at the rlew Jersey Station show that winter bud killing is not the \7iiole story of crop prospects. Some varieties set more buds per foot tiian others. Greensboro and Cumberland are among the varieties that form many buds while Siberia forms relatively few. Most var- ieties are intermediate but var:.^ greatly among themselves. The bud set of a given variety varies with growth conditions. J. K. Shaw Fruit Sales in Hew York City According to a U.S.B.A. report, the sales of leading varieties of apples in percent of total sales in rlew York City in i!ovember, 1939, v/ere as follows: luclntosh 33/^> Delicious 18^, R. I. Greening 1^.%, Cortland 7jj, Baldwin 6fu, Rome Beauty 5/o, York Imperial 2%, liorthern Spy 2't. These eight varieties made up 87/'- of the total sales. The retailers' "mark up'' on western apples varied from 24/0 to 35/3 and on eastern apples from 30fo to 45,f^ of the retail price, according to the type of store. The "mark up" on Cali- fornia oranges varied from 24/^ to 30/=; ^on Florida oranges from 20/S to 35/0, and bananas from 13/^ to 395^o. Spoilage was as follows: eastern apples, 2.4^ to 3.9/^; western apples, 2.6^ to 'ji'9foi California ^oranges, 3-3% to 4.2^; Florida oranges, 1.8,^ to 3.9/^; bananas, 7i% to 7.3/?. The total apple sales of the retail outlets surveyed were 952,664 lbs. weekly. j ^i s-^aw The Retailer Speaks The following notes from the Springfield School for Retail Grocers represent the unanimous or alm.ost unanimous opinion of 40 or more apple salesmen. 1. "\7e could sell apples fi-ster if tiiey \/ere all graded, - at least ^.ith the poorer grades separated." 2. "V.'e could sell apples better if they were all sized to quarter inches. V,T:ien tliey are mixed, people keep pick- ing them over and that ruins them." 3. "If ;^'ou could give us good apples only, we could sell all 3''ou grow." (Can't take this too literallj^, but tliere is something in it) . -3- 4. "A big orange crop do'isn't j.nterfore seriously with tlie sale of good apples. People just eat more fr-ait. vYe are selling more apples and more oranges this yoc.r than usual." (But this doesn't prove that a big orange crop doesn't affect the price of iipples. Also, conrumers have more money to spend this winter than for some time.) 5. "V.lien lettuce is cheap and good, v;e sell more apples for salads . " 6. "Think it might be a good iaea to mark culls "culls" when offered for sale. V'e'd ratJier not sell them at all." 7. "Several of the big cider mills are offering a very good grade of cider in the Springfield area. Some mills, especially little fellows, are selling poor stuff. They ought to have to clean up or quit the business. Good cider sells v/ell. The big demand is for clarified cider without preservatives. If tlieir cider ferments before we sell it, it is picked up by the good companies and put into vinegar. V/e don't get stuck v/ith it." 8. "The best early apple to sell is Gravenstein. " 9. "Local Delicious are coming in larger sizes than they did a fev; years ago. They sell better." 10. "V/e get some LIcIntosh that are fine in everything but color. They are hard to sell. Couldn't these growers do some- thing to get better color on their fruit?" 11. "The truck men ruin lots of Mcintosh by slamming them around. They are always in a hurrj;- to make z schedule and \Ye can't do anything with them. Ho, they don't slam eggs around, but that's different." 12. "VvTiy do so many fruit growers over-face their apples? The bottom of the boxes don't clean up and we have to allow for losses there to protect outselves." 13. "The Northeastern 'ci-ate' is the best package for local apples. They ought to be stacked on the sides. V/lij^ use cartons when v;e have to take the apples out to sell them? Two-pound or five-pound packages have not helped apple sales much so far, and we don't see much future for them in Springfield." P^^ ^^ y^^ j^j^^^^ Quality and Season There has been some disappointment this season, among growers and consumers, with the quality of some of our Massachu- setts apples. The idea prevails, especially among some "con- noisseurs" of quality, that many lots of apples, particularly / among the later varieties, are "beiov; par" this season. 'Northern Spy, Baldv/in, and more rarely Mcintosh and Cortland have come in lor criticism. In general, those J'.iclntosh that v.'ere allowed to hang on longer than the average, developed the highest quality. There are many factors, of course, which influence quality development in the apple as v/ell as in other fruits. Temperature is one factor. It is known tlu;t varieties differ in the amount of heat required during the summer months for optimum development. Duchess and Yellov/ Transparent, for example, develop at lower temperatures than Northern Spy and Baldv/in. Stayman and Winesap demand even more heci.t during the growing season. A heat deficienc:/" in any case may result in quality deficiency. It is interesting to note that there was a heat de- ficiency of almost two degrees in Massachusetts during the period, March through September. A difference of tv;o degrees, although rather small, may be very significant. For instance, the normal temperature for this period in Burlington, Vermont, is 56. 1° F. or just 1.60 F. lower than at Amlierst. As far south as Trenton, Nevv' Jersey, the temperatures during the same period average only about 4 degrees above ours. Of perhaps more importance are heat deficiencies in August and September v/hen apples tend to complete their maturity. In 194.0, the Amherst mean temperatures for August and September averaged I.70 F. and 1.6° F., respectively, belov; normal. It is possible that the loiver temperatures inhibit jQ maximum de- velopment of quality in some of our Massachusetts vt^rieties. It is well recognized that low temperatures during the final stages in the grov/th of peaches often result in delayed maturity and poor quality. Another weather peculiarity of the 1940 season which may have affected seme orchards adversely was the low rainfall in August and September - five inches below normal. La\7rence Southv/ick Here's an Idea At a recent Jlashoba meeting, A. B. Burrell of Cornell University discussed a J^-yeav spraying experiment in which the yield of young Mcintosh ti'T^es is being studied in relation to the scab control program. The first Block has received Lime Sulfur throughout the season for the past 4 years. The second Block has been sprayed \./ith Flotation Sulfur throughout. Block 3 has received Lime Sulfur before bloom and Flotation Sulfur thereafter, while in Block 4 this order was reversed. The aver- age yields per tree imder the four treatments for the entire period, 1937-1940 w«re as follows: Block 1 (L.S. only), 9 bu.. Block 2 (Flot. S. only), 13.4 bu.. Block 3 (L.S. fol. by Flot. S.), 13.2 bu.. Block 4 (Flot. E. fol. by L.S.), 11.2 bu. A dis- tinct biennial tendency was noted in tb.e trees sprcryed with L. S. -5- This v/as not the case m the trees receiving the milder fungicide. Furthermore, there was little reduction in yield v;here L. S. was used only in the pre-blossora sprays. The effect of caustic sprays on photosynthesis is v/ell knovm. Besides reducing leaf area. Lime Sulfur reduces the ef- ficiency of the leaf in the manufacture of starch. Biennial bearing under these conditions can be easily explained. Leaves thus handicapped throughout the season are unable to develop the current season's crop and at the same time set fruit buds for next year. A tree with uninjured leaves, the result of a v^'ettable sulfur program, is able to do both. Large, healthy leaves are able to manufacture the materials necessary for maturing apples of good average size, plus some reserve materials of vital im.- portance in annual proc.uction. But why should the trees v/hich received L. S. in the pre-blossom sprays yield almost cs much as those receiving no L. S. at all? This explanation is offered for what it's v/orth: Fruit buds are formed in June for the following year. If injury to the early leaves is severe, fewer fruit buds will probably form. Two L. S, sprays before bloom, however, v/ith no leaf in- jury later, would probabl: permit the formation of enough buds for" a full crop the next year, as heavy a crop in fact, as a tree \:ould normally bear. This sets the stage for annual bear- ing, i^nd since the leaves are permitted to function normally after bloom, under a wettable sulfur progrstra, the current season's crop develops much better than if the leaves were subjected to repeated applications of L. £. during the summer, as was the case in Block y^. Injury in the early spur leaves seems to have more influence on the next year's fruit buds than it does on the cur- rent season's crop. Hew Basis for Timing Curculio Spray Curculio beetles do little feeding on apples imtil the individual fruits attain a diameter of about 5/16 of an inch, according to the observations of W. D. liThitcomb of the V/altham Field Station. This fact offers a nev/ method of timing the 1st Cover Spray. Ten years ago, growers commonly apiilied this spray a certain nuiaber of days after the Calyx stage. But the results of this practice were variable. More recently growers have been advised to observe temperatures, since the beetles become increas- ingly active as the thermometer rises. And now comes still an- other refinement in the matter of timing. Warm weather, beetle activity and enlarging fruits are interrelated, '.."hen we realize that the surface area of an apple m.ay double in two days of warm v/eather, and that the film of spray material over the surface does not stretch, the necessity of careful timing is apparent. In the experiments at \.'althan the interval bet^/een Calyx and the critical stage in curculio control has varied be- tween 3 and 10 days, since 193-4. In only two of the seven years has the interval been as mucli as 3 days. -6- The relation of fruit diameter to degree of control is y;911 illustrated by these figures from Prof. I'/liitcomb. Mcintosh apples sprayed when the average diameter v/as A/l^-i^ch showed 13.3/b curculio injury. Other apples sprayed v;h.en 5/16- inch in diameter showed only L^.'S injury, while 6/16-inch fruit showed 12.8/j injur;/. In other v/ords^ the curculio did about 3 times as much damage on fruit sprayed v/hen 1/16 of an inch larger or smaller than 5/16. Other varieties sho\/ed smaller differences.. The corresponding figures for Gravenstein sprayed when diameters were 4/16, 5/16, and 6/ 16-inch, were 29.6f&, 13.4/"^ and 37.5^, respectively. Vflien Do Apple Maggot Flies Smerge? In the March issue of Fruit iJotes we shall show by graphs the 1940 emergence of maggot flies in three sections of the wortheast, - Massachusetts, Connecticut and the Hudson Valley. Growers often express the opinion that flies are emerging later than is commonly supposed, since they are observed in the tr^es as late as mid-September. The above mentioned data seem to shov; that the majority of the flies emerge before the first of August. Damage to late varieties is apparently due in many cases to flies migrating from other trees. gffects of Stacking Mcintosh Apples "on the Bulge" To measure the damage caused by careless handling of packages, the following experiment v/as performed at the State College a few weeks ago: Fancy Mcintosh apples, 2^-" and up, were jumbled with high bulge (3/4 to 1") in iiortheastern crates and stacked four high on the bulge. The crates v/ere moved three times, handling without undue roughness. The bottom crate which contained 131 apples v/as checked for bruises on January 14 v;ith these results: 21 apples had stem punctures; 36 had major bruises (| to 1%" in diam.); 59 had less serious bruises (1/8 to 3/4" in diam.); 15 apples v/ere free from injury.

FRUIT NOTES - March, 1941 IV. H. Thies Extension Morticulturist Costs of Tree Removal the Maryland Fruit Grovrer reports removal costs of a 40-year old apple orchard, as follov/s: In 1939, 340 trees were pulled with a 10-ton Caterpillar tractor, rented at ^:1.50 per hour and using an ojj.vrator and four helpers. The cost of pulling, triiraning and sawing t}ie trees, burning brush, dragging out stumps, cording and hauling the wood was 31^ per tree. After the cordvrood v;as credited back at ^;1.C0 per cord, the cost amounted to 49/ per tree. V.Tien the cost of filling stump holes, disking and levelling was added, the total cost was ^1.12 per tree, or after crediting the cordwoodj 68.7/ per tree. This cost probably v/ould be much less where trees are ahoppeT or sawed and the stumps left to rot. R. A. Van Meter Elastic Demand for Apples Recent studies indicate that consumer demand for apples is more elastic than for most other staple food products, even exceeding that for oranges. An increase in consumer incomes such as v.'e are now experiencing will benefit mostly those growers \'/ho produce the better varieties and the higher qualities. Consumers will pay more for good fruit if they have the money, but vrhen incomes are low they buy cheap fruit or none. It has been predicted that v.'e are entering another "silk shirt" period. If that is true there should once mere be a real margin of profit in fancy fruit put up in most attractive form. R. A. Van M'-ter A Note on Strawberry Plants The following statement is taken froxfi Michigan Technical Bulletin llo. 162, - "There is no indication that the importation of plants from out- side the state is an advantage if locally gror.oi plants free from insects and diseases are available." As a matter of fact, this bulletin shove's a substantial increase in yield of freshly dug, locally grown plants over most lots shipped in from a distance. The same bulletin presents figures to shovi' that only plant.'-- with large crovms should be used in setting a new bed. The inceade in yield of such plants over smaller crovnied plants was more than 15^. Thinning matted rov: plants to six inches at the end of t'.ie growing season, t:) reduce over crowding, not only failed to improve the yield but actually decreased it 2byl. A. P. French Winter Injury in Mid-western Orchards The severe cold wave that prevailed over the Midwest last ITovember did great damage to orchards, ;• low zero temperatures followed closely a period of summer-like weather while the trees were still in leaf. Damaged orchards extend from Iowa to central Missouri and Kansas and from western Illinois to eastern Nebraska. Trees up to 15 years of age end the more ten- der varieties suffered most. Estimates of the severity of the injury differ -2- but it appears that a quarter to a half of the apple trees in that area were put out of business for a time at least. Peach orchards and other stone fruits were severely injured. V.Tien v/e add to this the nev.s that tractors are doing a big business in pulling apple orchards in Washington, and the more or less extensive pulling of uneconomic orchards all ov^r the dour.try, it appears that the national apple crop will fall to the level of domestic consumption. J. K. Shaw Phosphorus and Potash Under a Mulch Vforkers at the Kentucky Agricultural Experiment Station find that omission of phosphorus from nutrient solution cultures seriously affect apple and peach root development, especially fibrous roots. The trees grown with- out phosphorus vrere much smaller than those receiving phosphorus. This element is, of course, necessary for all plant growth although there is little evidence to show that fruit trees in 'Massachusetts are suffering from phosphorus deficiency. An application of phosphorus in a sod orchard may never get into the trees because it is soon fixed in unavailable form near the surface of the soil. The use of mulch brings feeding roots of the tree to the surface where thej' have a better chance to absorb not only phos- phorus but potash. It is thought that the presence of decaying organic matter in the soil tends to keep phosphorus and potash in an available fcrm. Feeding roots in the zone of decaying nrganic matter have a chance to ahjorj these mineral elements before they become fixed. Trees which develop a mat of fibrous roots under a mulch v:ill also develop deep roots if subsoil con- ditions are favorable. J. K. Shaw Further Observations on Modified Atmosphere Storage V.'e have opened the modified atmosphere storage room in our cold storage. The room was sealed October 11, 1940 and the oxygen content dropped from the normal 21;'^ to about 13^ within a short time. It continued at about that level for several weeks indicating that the room was not sufficiently gas tight. The room was opened on February 24, and further precautions v;ere taken to make it gas tight, including an improvement of the door seal. Fol- lowing this the oxygen content gradually fell to around lO^o where it con- tinued with small fluctuations. This behavior indicated that leakage was decreased but that the room was still not tight enough for respiration to bring the oxygen dovm to the desired 2ja. On examining the empty room we found one place that gave opportunity for some leakage. This may help to explain the failure to obtain the desired composition of the atmosphere. The apples are now being examined for condition and quality. They seem to be in good condition and of a quality equal to or better than others stored in nor- mal air at 32° even though these apples were stored at 40°. Our experience this year has been somev;hat disappointing, but we feel that the difficulties encountered can be overcome and that modified atmosphere storage does have distinct possibilities. Great pains must be taken to see that there is the least possible leakage, that the room is filled to capacity and that air cir- culation is sufficient to assure apple temperatures uniformly close to 40°. J. K. Shaw Shall y.'e Plant a I^ew Orchard? There seems to be a surplus of nursery apple trees thic sprLn,-, and prices are low. 7.1^116 this is no time for extensive and indiscriminate planting, it is clear that unless more orchards are set, apple production in ^3- Wev; England will decline in the near future. " ■ are able to compete success- fully with other regions, and competition hac always determined the course of the apple industry. There are competent grov/ers who might wisely take advantage of the present situation by planting trees to replace unprofitable varieties and thus bring about a better economic organization of the enter- prise. But be careful of sites and so^ls. V'e have too many unprofitable orchards planted on soils better suited to other uses. J. K. Shaw Clonal Rooted Apple Trees A few nurseries are offering apple trees propagated on numbered Mailing rootstocks. Fruit grovv-ers should bear in mind that the different rcotstocks produce variable degrees of dwarfing on the topworked variety. At the present tim.e trees on only 3 or 4 of the 16 j.lalling rootstocks are listed. Experimental and cooperative orchards in l.!assachusetts and other states are expected to give much valuable information as to the usefulness of clonal stocks for many apple varieties. Evidence to date indicates: Mailing VIII and IX are very dv;arfing; Mailing I, II, III, IV, V, VI, and VII are semi -dwarfing; Jlalling X and XIII are probably somewhat dwarfing bu-^ evidence is conflicting, especially with },!. XIII; Mailing XII, Z7, ai'-d X/I are vigorous. All clonal-rooted trees should be set with the union (of stock and scion variety) slightly above the ground in order to forestall scion-rooting which would tend to mask any stock effect. This is especially important with trees on the dvmrfing t;,^es of stock. L. Southv.dck Bitter Pit of Apples (Stippen, Baldwin Spot, etc.) E'itter pit xhas been recognized for many years as a serious function- al disease of apples* Yet, the real cause is still uncertain, and complete control measures have not as yet been fcund. Li^;ter pit originates in the orchard. It may be detected at harvest and nay develop in storage, especially during the first three months. Affected fruits show brov.T., irregular, pitted areas that are bitter to the taste. The flesh is primarily affected, and the skin cells die follov;ing the collapse of the underlying cells. The apples usually are not saleable. In Canada, the most susceptible varieties are re- ported to be Stark, Baldwin, Blen'"eim, Nortnern Spy, and to a lesser extent Ribston, Gravenstein, and Yellow ilewtovT.. In Vermont, the most seriously affected varieties have been Arctic, Baldwin, Spy, and Sniawassee. Many other varieties show pitting in some seasons. Mcintosh is about as immune as any variety, although some pitting has been observed on some of its seedlings. At Cornell, it has been observed that any treatment v/hich accentuates compe- tition for water betveen leaves and fruits will increase susceptibility to this disease. Such treatments as heavy nitrogen applications, shading, and gird- ling tend to increase pitting. Few leaves per fruit on the tree and high humidity in storage tend to inhibit bitter pit. L. Southwick This and That PhotosjTithesis . Studies at Cornell indicate that varieties may behave differently with respect to tiie rate of photosynthesis at different times of the day. "Tiereas Baldv/in seemed to be more active in the morning than in the afternoon, Mcintosh seemed to be just about as active photos;,.Ti- thetically during the late afternoon hours as in the early morning. -4- Mulching. In ITev.' York a mulch of v.-ood shavings showed no injurious effects on apple trees after three years of use. Apple pomace used as a :nuleh caused serious injury and some killing of trees. ■More Oranges and Crrapefruit. The March 1 estimate of total 1940-41 (Sept. to Aug. J orange and grapefruit production v.-as 4.8 million tons com- pared v;ith 4.3 million tons in 1939-40. Good Demand for Apples. According to the Bureau of Agricultural Economics, February auction prices of leading varieties of western apples averaged slightly higher than those of a year earlier, despite the larger cold storage holdings. On March 1 these holdings v.ere still 2.4 million bushels greater than a year earlier even though the February out-cf-storage movement v;as 300,000 bushels greater than in February, 194C. L. Southv/ick Pruning and Tree Vigor ' In years past v;e were given this advice: "Prune vigorous trees lightly; weak trees, heavily." Back of the advice v:as this fact. Good growth accompanies good fruiting, and since vigorous trees already have the kind of grovrth needed for fruit production there is no need to stimulate additional growth, as for example by branch removal. Not so with trees shovd.ng scanty grovrth and a general lack of vigor. Such trees need pepping up. But the pruning saw is not the only available tonic. Today, liberal annual use of nitrogen provides the new growth which yesterday v.e tried to prune into ex- istence. This merely suggests our modern program of balancing fertilization and pruning. These practices supplement one another. Experience has sho^^'n that an over vigorous tree cannot be pruned back to normal. The same is true of the weak tree. The bag of fertilizer and the pruning saw together make an efficient team. Michigan Supreme Court Upholds Advertising Act The Supreme Court of Michigan handed down two decisi.ons on Feb. 11, upholding the entire Michigan Apple Advertising Act. In sc ccing, it reversed decisions of tvro louver courts which had caused a complete cessation of activi- ties by the state Apple Commission since December, 1939. The advertising Act provides for the assessment of 1 cent a bushel on Michigan apples prior to shipment, to b e expended by the Ilighigan State Apple Commission for advertising and related purposes. It was patterned after the law now in effect in the State of "Vashington, and Is similar to lav,rs in Florida, Maine, and Idaho for the advertising of citrus fruits, potatoes, and other products. In its ruling, the Supreme Court declared that the tax is not dis- criminatory. "The tax in question is a levy upon putting Michigan grovvn apples in the marts of commerce ... It applies only to those who put their apples in the marts of commerce and is applicable to all that class without distinction.' V'e must assume that the advertising for which the funds are expended will accomplish the desired purpose, namely, stimulation of the use of Michigan apples, with a consequent increase in production and distribution . . , Statistics indicate that the consumption of apples has shown a marked decrease while that of citrus fruits, extensively advertised, ha^ corre;-por.dent • ly increased. Thet the production of apples is not an infant opcupation is settled from the fact that the average annual value of the crop in this state -5- for the past ten years has been $6,785,000 dollars, exceeding the combined value of peaches, pears, grapes, cherries and plums. V.'e perceive that the stimulation of so large and important an industry will result in a benefit to the general public v.'ell-being, the increased prosperity of the entire apple growing industry of necessity being reflected throuf'hout the ccr.:n' :.- wealth . . . V'e hold that the tax is for a public purpose." At a meeting following the action of the Supreme Court, the Apple Commission announced that no effort will be made to collect the advertising assessment on the 1940 crop. Plans are being made, vrith the cooperation of the Ji'ichigan State Horticultural Society, for a series of grower meetings over the state in the near future, as a preliminary to getting the program under v.'ay again for the 1941 crop. Trees That Don't Groy^ flave you ever vmlked through an orchard and observed an occasional tree which made practically no terminal -rrov.'-th? IP so, the chances are that the tree was either girdled by mice, attacked by borers, or had suffered root injury. Many of the hurricane dajria£:ed apple trees are in this class. In some cases practically every grovring point is developing into a fruit spur instead of making a normal growth. Even the terminal buds have taken on a spur-like appearance. If only one sid'^ of the tree v.as seriously damaged, these symptoms may appear on tho-"- side while the rest of the tree may be more or less normal. This item is being written as a reminder that unsatisfactory groiAi;h in a fruit tree is not always an evidence of need for additional fertilizer. The real cause in many cases is a partial separation of the top and the root system. The situation is briefly this. If a mouse destroys the bark at the base of the trunk, the channel through v:hich carbohydrates flov; from the leaves to the roots is disrupted. Hew root grov.rth under these conditions is practically stopped. If such a tree is bridge grafted the channel is restored and the tree functions as before. In hurricane damaged trees v.'here large roots were broken near the point of attacliment to the trun'-' the ch^in- nel through v;hich carbohydrates flov/ to the roots is disrupted in mucli the same way as if the tree were girdled. Hence the similar appearance of growing points in the top. It isn't entirely a question of v.'ater and min- erals from the soil failing to reach the top, but rather a failure of food materials from the leaves reaching the roots. As we observe terminal growth in individual trees it is advisable to use a shovel or hoe occasionally to check the condition of the loiver part of the trunk to detect hidden mouse injury, borers, etc. Good grovrth is generally a question of a good nutritional setup as regards . Ineral elejiients and moisture. It is also closely associated vath a Jiealthy set of conducting tissue throughout the tree. Nev; Movie, "Apples Go to Market" A natural color movie of special interest to handlers of apples, particularly dealers and retail store clerks, has just been completed. This movie points out in an interesting way the relation between care.'^ul handling and consumer satisfaction.

FRUIT NOTES - April, 1941 Y^. H, Thies Extension Horticulturist Buying Fresh Fruits and Vegetables for Army Posts Following is a summary of a release by E. V.'. Bell, Extension Econ- omist, of interest to fruit and vegetable growers: The importance of fresh fruits and vegetables in the soldier's daily diet is fully recognized by U. S. Army authorities. Those responsible for feeding the army are insisting that each soldier get the maximum quantity possible within the ration allow- ance. This summer the army will be feeding about 1,500,000 men. Almost 60,000 will be quartered in army posts in Massachusetts. Begirining May 1, a new system of purchasing fresh fruits and vegetables will be inaugurated. Thirty purchasing offices will be opened throughout the United States in close proximity to army posts. One of these offices will be located in the Boston Market Terminal Building, Rooms Z71-273 (Tel .-Hubbard 1248). An ex- perienced civilian producer-buyer, classified as a "marketing specialist," will serve as adviser. The buying office in Boston will fill the requirements of fresh produce for such army posts as Fort Devens, Camp Edwards, Yv'estover Field, and the Harbor Defenses in Boston and New Bedford. Purchases will be made daily, weekly, or monthly on a competitive bid basis to supply the needs. The lowest responsible bidder will get the award. All purchases will be made on the basis of delivery to army posts, and in accordance v.dth federal grades. Inspection will take place at the post vrhere delivered. A grower wishing to sell a shipment of produce should proceed as follows: (1) Contact buying officer at Quartermaster Corps Marketing Center, Perishable Subsistence, Boston Market Terminal, South Boston, Mass. by tele- phone, telegraph or letter. (2) Register quantity for sale, delivered price, kind of produce, and dates when delivery can be made. If done by telephone, confirm by telegraph or letter. Quotation should be made at least three days in advance of delivery date (a week or 10 days is better). (3) Delivery awards on quotations will be made with instructions as to where, when, and how much to deliver. (4) Delivery to army posts should be accompanied by invoice stating kind of produce, number of packages, price bid, and grade and specifications required. (5) Inspection will be made at time of delivery, and number of packages will be checked. (6) Pa;;,'ment will be made from the buying office in Boston after a period of about two weeks. Planting Fruit Trees The important thing in planting trees is not merely to make them live but to make them grow vigorously from the start. Then they may be de- veloped into strong trees vdth little pruning. A tree that grows slowly for the first tvro or three years is likely to drag behind all the rest of its life and almost certainly will have a poor framevrork. Keep nursery stock fully dormant until planted by keeping it in cold storage or in the coldest place you can find. Plant it Just as soon ., ,, •;/>«*!?■■. .•.;.5,;w: ■ - : ■^■-.■» f ^, fc ,• •'e v.*i ; .'( ■-•*. .■ ^' J ; -2- as the ground dries enough to crumble. If this is done, new roots v;ill de- velop while the air is too cold for buds to break, and v;hen leaves do appear there will be a root system ready to supply them with water. In planting it is a good plan to get out the sprayer and wash in the soil around the roots. The amount of pruning has much to do v;ith the start made by the tree. Planted under ideal conditions a one-year old tree needs little or no pruning. But do not hesitate to prune severely if there is any question of a vigorous start, even to cutting the tree to v;ithin 6 inches of the ground in extreme cases. A vigorous start is the main objective. If the tree grows vrell the first year there will be a strong shoot growing up, on which the top may be built later at any height desired. If the tree starts slowly the central leader usually is lost right there, never to be regained. I think I never saw an apple tree that grew too much during the first year in the orchard, but I have seen thousands that grew too little - and never got over it. Remember, the central framevrork of the mature tree is developed in the first 3 or 4 years. The first year is the most important year in the life of the tree so far as shape of the tree is concerned, and the first month is the most important part of that year. Llake sure that the tree is not stunted by transplanting. Make it grovj-! R. A. Van Meter Hand Pollination of Apples Bees native to the irrigated valleys of the Northwest live in the ground. Irrigation drives them out. Imported colonies of honeybees tend to visit plaiits in surrounding non-irrigated areas and neglect the apple trees. Under these conditions, hand pollination of apple trees is proving profitable, sind thousands of acres of apple orchards are pollinated each spring by hand in that section. Blossoms are collected just before they open and rubbed over a screen to remove the pollen. The pollen is applied with a camel's hair brush. The labor cost of an experienced man in pollenizing a mature apple tree amounts to 25 to 35 cents. Two or three ounces of pollen are required for an acre of trees. Not all blossoms are pollenized but only enough to give a well dis- tributed crop. Northern Spy groovers in western Nev; York have long had trouble in getting a satisfactory set of fruit. This may be due to the fact that Northern Spy blossoms are not very attractive to bees. Now many grov/ers are hand pol- lenizing Spies by pruning pollenizing varieties at blossom time, throwing the branches in a hay rack and, standing on the rack, brushing the Spy trees with the pollen-bearing branches. This method is said to be effective and not too expensive. It is doubtful if hand pollination would help many trees in New England. Bees find pretty good working conditions here and may be obtained at reasonable rates. Y.lien Nev: England orchards fail to set satisfactory crops year after year, it is generally due to low vigor. Under these conditions, hand pollination would be of doubtful value. There may be a few blocks, hov;ever, where the New York method might well be tried. R. A. Van Meter -3- A Note on Apple Yields X'ie cannot boast about high yields froni some of our experimental orchards at the College. Many trees, for purposes of comparison, are handled in v/ays knoviii to be unwise for commercial growers. But the Mcintosh trees in our mulch-cultivation comparison have given a good account of themselves. Over a 10-year period while these trees were 16 to 26 years old, the mulched plot averaged 585 bushels per acre per year, and the cultivated plot 400 bushels. The highest yield, 1269 bushels per acre, was taken from the mulched plot in 1936. These are total figures, conservatively calculated from the yield of 18 trees. About 20-25^ of the apples were "drops" and about 10/J were not salable. These are not remarkably high yields. Some coinmercial growers do as well, if not better. All should try to. But why, an occasional individual asks, should we strive for higher yields when there are apparently too many apples now? For the country as a whole, there may be an oversupply. But for the individual grower, larger yields lower the per bushel cost of production and thereby increase the opportunity for profit. Cutting dovm unprofitable blocks of trees is a move in the right direction, J. K. Shaw 1940 Farm Income in the U. S. According to preliminary figures, the 1940 cash farm income in the United States amounted to .;S, 354, 104, 000. In addition, government payments to farmers totaled .;i; 765, 799, 000. Iov;a had the largest farm income, $679,271,000, followed by California, Illinois, and Texas. Rhode Island, with $9,889,000, showed the smallest income. A figure of <^75, 609,000 is given for Massachusetts. Cash farm income by crops showed cotton lint in the lead, with a value of ^573,401,000. VJl:ieat, truck crops, corn, and tobacco were next in order. Income for apples was C^Sl »417,000, peaches - 034, 701, 000, strawberries - $40,885,000, and cTtnTs fruits - $129,790,000. Total crop income was $3,535,712,000 comparedTo the total livestock income of |4, 818, 392 ,000. L. Southwick Labor Returns From Various Farm Crops Labor spent in pro"ducing dairy products in "ew York State returns 25/ per hour, poultry 28j^, and apples 39/. These figures are presented by V. B. Hart of Cornell University. Ke points out that the hours spent on dairy and poultry farms, while returning a comparatively lov; rate, often in- clude hours that could not be used on other enterprises. Therefore, it is to be expected that they would return less per hour. In the case of apples, the season of profitable emplo;/ment is relatively short while dairy work is a year round proposition. The returns from other crops are as follows: wheat 52/, alfalfa 60/, beans 30/, cabbage 55/, potatoes 54/, tomatoes 41/. Ideas on Apple Storage 75 Years Ago In"tl7e 1866 report*~of the Essex Agricultural Society there appears an article by Robert Llanning on the "Preservation of Fruit and Construction of Fruit Houses." He says, "Ripening of fruit is a completion of the chemical process by which starch is transformed into sugar. It is the first step toward decay." He mentions seven principles of storage, as follows: (l) Un- less fruit attains a certain degree of development on the tree, the ripening -4- process will not continue after it is separated from the tree. (2) Harvest carefully. (3) Protect fruit from frost. (4) There must not be too great a degree of heat for that is the most powerful agent in promoting fermenta- tion. (5) Maintain uniform temperature. (6) Keep in darkness. (7) The atmosphere must be uniformly dry. With the exception of this last suggestion, Mr. Msjuiing's principles are reasonably modern. Evidently he had not experienced the severe shrivelling which occurs in certain varieties like Russet when kept in a dry storage. Today we are convinced that high humidity in the storage is essential. Do You Know That Columbus is supposed to have brought the first orange seeds to the New World on his second trip to America? Either Ponce de Leon or De Soto introduced the orange to Florida. Early missionaries carried the fruit north from Mexico into California in the 17th Century. That the codling moth is said to get its name from the fact that its larvae causes small and gnarled fruit? In England these apples are called "codlins" just as small ears of corn are called "nubbins." lYho added the "g" or when it vras added is not kno^<^al. That approximately 500,000 bushels of apples went into apple juice in Michigan last season. Most of the juice was canned in 20 and 43-ounce cans. Apples for apple juice bring the grower 20 to 50/ per hundred pounds. Y'Diile this is not a large price it does make an outlet for a type of apple which should not be sold on the fresh fruit market. That the labor investment in spraying in one large, successful orchard amounts to less than l/S of the total labor involved in producing sind marketing the crop? Spraying costs, including labor, materials, and depreciation of equipment ought not to run higher than 20)^ per bushel. Some grovrers produce a good crop j^ear after year with a spray bill amounting to 10 to 15/ per bushel. That fruits other than apples are also seriously affected by the loss of export? Apple growers have lost export markets for about 10,000,000 bushels while citrus growers have lost markets for 3,000,000 boxes of oranges and grapefruit. Exports of prunes this year are expected to total only about 18,000 tons compared with 108,000 tons in the year before the war. Raisin exports will total only about 15,000 tons this year compared with 76,500 tons the year before the war. That the Blakemore variety of strawberry makes up about 25^ of the strawberry acreage in the United States? The next 15 varieties in order of importance are as follo\vs: (The number following each variety is the percent of the U. S. acreage.) Klondike-14, Aroma-11, Marshall-10, Howard 17-9, Missionary-5, Catskill-4, Dorsett-4, Fairfax-3, Dunlap-2, Klonmore-2, Hick Ohmer-1, Joe-1, Chesapeake-1 , Beaver-1. Mastodon is 16th on the list although it stands 6th in nursery sales. That fruit grovrers received an average of 35 cents of each dollar -5- spent by consumers for apples in 1940? Percentage figures for other products quoted recently by V*". E. Piper are as follows: green beans 54/, cabbage 18/, carrots 20/, lettuce 37/, onions 5l/, spinach 40/, canned peaches 11/, canned corn 13/, white flour 40/, rice 29/, corn flakes 18/. Growing Small Fruits for Home Use Ever watch a portly lady hopefully check her v/eight on a restaurant scales, and then order the usual calorie-laden meal? Not so with the modern Miss. By shunning starchy foods, she saves her sylph-like silhouette. Here's what's happened in the past 15 years. Per capita consumption of potatoes is down 12^, and cereal products, 14°':, while vegetables are up 25^? and fruits, b%. But that's not the whole story. Folks v.'ho grow their own vegetables and small fruits enjoy not only the health giving qualities of these foods, but the fun that comes from a productive tussle with Nature in the backyard. Unless you've experienced the thrill of picking a quart of your ovm fresh strawberries as the June sun peeks over the horizon, you still have something to live for. If your slippers become soaked v.dth dev/, that's unimportant. And the exercise, an unexpected dividend accompanying the harvest, will tend to insure your slender form. Seriously, there's much to be said in favor of a planting of small fruits on every farm. Strawberries, raspberries, and grapes require less spraying than tree fruits. They bring quicker returns, and they occupy less space. A succession of snail fruits makes a real contribution to a "live at home" program. Apart from the money value of the fruit, there's a satisfac- tion in having one's fill of berries in siommer, with a few extra quarts for jam.. If you were to find a ^10 bill, you'd doubtless be happy. And yet an area 20 x 20 feet is entirely capable of netting that tidy sum in terms of luscious strawberries. "Better living from the land" becomes more than a slogan if it finds expression in a vrell-pla.nned garden of small fruits and vegetables. Subsoil Important in Raspberry Plantation A recent raspberry study in Nevj Jersey is suminarized in State Horti- cultural Society News as follows, "It is very clear that soils underlaid by heaver material, which is of great importance in providing a moisture reservoir, are best adapted to the growth of Lathain raspberries. Before setting out new fields growers should examine the subsoil and avoid setting raspberries in soils too light to maintain a sufficient moisture supply throughout the grow- ing season." The num.ber of strong canes in portions of the field underlaid by loamy sand, sand, or gravelly sand, v.^as much less than where underlaid by a subsoil containing some clay. The use of a salt hay mulch with a generous application of fertilizer and lime helped to overcome the handicap of a porous subsoil. Massachusetts raspberry grov-rers may v.'ell consider mulching, parti- cularly where raspberries are being grovm on a relatively light soil. Nevj- Fruit Laws in the Northwest Quoting from a recent issue of Better Fruit, "By the time this issue reaches you there will be two new lav,-s in the State of V.'ashington, both of vital interest to fruit growers. One is an orchard sanitation law, designed to speed up removal or destruction of pest infested orchards on properties which are a nuisance to adjacent farms. Second is a law designed to control pear psylla, newest Northv.'est orchard pest which specializes on pear trees." 'r ;:^''-l"\- -6- Virginia Orchardists Remove Trees Under Conservation Program Over 18,000 apple trees in Frederick County, Virginia have been removed or vj-ill be pulled out under the Agricultural Conservation Program. Trees thus removed are diseased or of unprofitable varieties. Many trees selected for destruction are of the York Imperial and Kammoth Black Tv:ig varieties. The 90 growers participating in the tree removal program will receive approximately $5,200. Apple Juice Conference in Michigan Michigan apple juice manufacturers held their second conference March 20 at the State College. New methods in processing and packing apple juice were discussed. Much interest is being shc-vm in a new process which makes it possible to extract, pasteurize, and pack apple juice in about 4 minutes, instead of 24 hours by old methods. The quick process is said to preserve more of the original color and aroma of the juice. Prune Pit Oil Proves Useful Studies at the University of California indicate that oil crushed from the pits of prunes may be usefizl in preserving the prunes themselves. Prune pit oil is reddish in color and has a pleasant aroma and taste. It is relatively rich in vitamin A and in vitamin E. Two lots of prunes were spraj'ed with this oil and stored. These prunes retained a larger amount of moisture and proved a juicier product than those which were stored with- out spraying. Meet Competition at Home Follov.'ing are a few quotations from a trade journal editorial sub- mitted by John Rice of Marlboro, - "The biggest single problem confronting the fresh fruit and vegetable industry today is one of salesmanship. In the first days of the 'quick frozen' competition v/ith fresh commodities, some men in the industry v.rarned that if not checked it one day would become a real menace. Today the housewife is not only enabled to get quick frozen food from the grocery all prepared for immediate cooking, but if she prefers to stay at home the quick frozen morsels will be brought to her in refriger- ated cars. 'Shop at Home Service' is the latest v;rinkle. Routes have been laid out, salesmen make daily calls in the kitchen, give the homemaker hints on v/hat are the best buys, and do everything but cook the meal. Housewives are told in effect, why bother picking over berries, shelling peas, and cleaning spinach when you can have it 'frosty fresh' and compactly packed? The purveyors of fresh fruits and vegetables have raised their voices against the word 'fresh* in describing processed fruits and vegetables. The quick frozen competition must be met. And the best way to meet any competition is to beat it." Deer Control in Connecticut V,'. P".~ Judkins of the Univ. of Conn, is attempting to keep deer out of the College orchard by means of an electric fence. V/riting in Fruit Re- search Notes he says, "In order to prevent further injury an electric fence was erected in early September. This fence, which is made of two strands of wire located 25 and 42 inches above the ground, has given good results thus far and no further damage has been observed," He is also experimenting with repellent paints to prevent rabbit injury in young trees. Some of the re- pellents have caused considerable injury to peach trees. He feels that more data are needed before any repellent paints can be recommended. !V1« Leaf Hoppers Affect Leaf Activity If an apple leaf" shows the characteristic mottling due to leaf hoppers, v»'e can be sure that it is not producing a normal amount of starch. Lack of size and color in apples may be traced directly to a heavy leaf hopper infestation. Careful studies have recently been made at Ohio State University to shovi the effect of leaf hopper activity on the functioning of apple leaves. A heavily infested leaf after seven days of leaf hopper attack v:as producing ci5% less starch than a normal leaf. As a result of this study the workers conclude that a 20-50^o reduction in daily food manu- facture by an apple tree, beginning early in the season, can appreciably reduce the total amount of food which goes to increase size and color of the fruit, and at the same time form fruit buds for the following year. Leaf hoppers can dart forvjard, shift to the right or left, back up and dodge as cleverly as any insect in the orchard. This characteristic makes it difficult to hit them v.dth spray material since they usually dart to the leeward side of the branch or leaf when spray is directed at them. A spray intended for leaf hopper control must be directed upward to cover the lower sides of the leaves. Otherwise the investment in spray material is largely wasted. Codling Moth One of Oldest Insect Pests Qg^^Q^ abou-TSOO B.C. and Pliny in the first century A.D., wrote about "wormy apples." These apples were doubtless infested with codling moth. In 1635 a Dutch scientist v/rote a treatise on codling moth and drew pictures of it in various stages of its development. Under one name or another the codling moth has plagued human apple eaters since the dawn of history. The native home of the codling moth was southeastern Europe but early in the 19th Century it set out to see the world. ITithin that century it spread over Europe and into Australia, Tasmania, New Zealand, South Africa, and North and South America. It was first reported in the United States as in- festing apples and pears in 1819 near Boston. By 1860 it was attacking fruit in lovra, and in the spring of 1874 it appeared in California. It is now one of the worst fruit pests in every apple producing area. Try This with Your Soil Auger Fn' a recent issue of "The Soil Auger," A. B. Beaumont makes this suggestion: "Find a slope of 5% or greater, 300 feet or more long, which is known to have been under cultivation for a number of years. It need not have been cultivated recently. Take borings near the top v;here erosion would be expected to be severe and note the depth of the top soil, which can be de- termined in most of the upland soils of Massachusetts by sharp changes from dark brown to yellowish brovm. Do the same at the foot of the slope. V'hat depth of top soil do ycu find at each place? Many tests of this kind in Massachusetts have shown the top soil on the upper slope to be 3 to 7 inches deep; at the base 3 to 5 feet deep." This suggests not only an urgent need for erosion control but for a different fertilizer program at the top and at the bottom of the slope. New Soil Conservation Bulletin ^Con"s'ervatToir'of~Mas"sachusetts Soils" by Beaumont and Kucinski, is just off the press. If interested, ask for Leaflet ^^193. This publication covers kinds of erosion, distribution of erosion, factors affecting water erosion, wind erosion, methods of soil conservation, and influence of organic • '^-t^-fr matter. It is well illustrated and contains an interesting summary. Three Timely Tips {!) Bid you have trouble with rosy aphis last year? And are your buds still in the dormant stage? Then there is still time to apply the nev^-- DN spray v/hich is proving very effective in aphis control. (2) Have you any apple trees which are reasonably young and vigorous although of the vn-ong variety? Then you are just in time to top graft them to something better. Late April is an ideal time and there is no better grafting wax than the Icind which you can make yourself. For details, see Leaflet 117, "Top Grafting Fruit Trees," (3) Have you any apple trees under 4 years of age? Are you perfectly satisfied v;ith their present framework? The 2nd and 3rd years are very important in developing a ^.ood framework. If nothing is done until the trees are 4- or 5 years of age, shaping is difficult with- out making drastic cuts. YJe suggest that you look over your young trees again and do v;hatever pruning is necessary. \'Tho Has the Largest Apple Tree? Not long ago a Connecticut grower spoke of an apple tree in his orchard with a trunk diameter of about 3 feet, A tree of similar diameter is reported in Franklin County. These reports have aroused our curiosity. Maybe we can locate the largest apple tree in Massachusetts. If you have a tree with trunk diameter of more than 3 feet and are willing to invest in a post card, please send us the details. Revision of College Mailing List During the next few months a complete revision of the various College mailing lists if planned. E. S. Carpenter, Secretary of the Ex- tension Service, says, "Instead of sending John Jones, vrho may be receiving four publications, four different letters, we plan to insert the names of the various monthly publications he receives on a letter which will be sent to him. Then he will check and return to us. I suggest that you run a notice in your April and May issues of Fruit Notes that the mailing list is to be revised."

FRUIT NOTES - IJIAY, 1941 W. H. Thies Extension Horticulturist Effect of Air Temperatures on Mcintosh Development During the last 20 years the date of full bloom of the Mcintosh apple at Amherst has varied from May 3 to 22, or nearly three weeks. The average date of bloom is very near May 14. The duration of bloom has varied from about 3 days to nearly a week. Our dates of harvest are not complete and are not reliable as indicating maturity of the apples. 17e novi pick Mcintosh later than formerly. There is no reason to expect any marked correlation be- tween dates of bloom and of maturity. A little reflection shows why this is true. All plant grovrth and development rests on chemical reactions and obeys the laws of chemical reaction. Within limits the higher the temperature the more speedy the reaction. Y.Tien apple trees bloom early it is because of above average temperatures in early spring. If early bloom is followed by above average temperatures during the growing season, the harvest v/ill be very early; if summer temperatures following early bloom are low, maturity will be near normal. In 1938 Mcintosh v;as in full bloom on May 3 and in 1940 on May 20. The departures from normal temperatures were as follows: April May June July August September 1938 +3.5 -1.5 tl.4 +0.9 +3.8 -2.3 1940 -3.6 +0.1 -1.1 -0.2 -1.5 -1.6 The April departures show why blooming dates were different. '"Je believe that the low summer temperatures in 1940 vrere more effective in causing late ma- turity than the late date of bloom. J. K. Shavj- Ringing or Scoring Apple Trees to Hasten Bearing About 20 years ago we carried out some experiments at the State College with ringing 8-year-old Viealthy, Oldenburg, and V.'agener trees to hasten bearing. There are two v/ays of carrying out this treatment: (1) Ringing consists of taking out a narrow ring of bark from the trunk or main branch of a tree. This must be rather carefully done. If one wishes to be safe he may tie a sheet of paper around the tree so as to cover the bare ring, though usually this is not necessary. (2) Scoring consists of cutting through the bark of the trunk with a strong knife, making two or three rings, Vidthout removing any of the bark. Either of these processes favors the accumulation of carbohydrates in the top of the tree and frequently promotes fruit bud formation. The time of ringing or scoring is important. Inasmuch as fruit bud formation becomes evident in late June or early July, it follows that the op- eration must be performed in late May or early June. Treating trees later is likely to be ineffective and leads to poor yield and weakening of the trees. Treating a tree that has a good to heav^'' crop is not only ineffective in bring- ing about fruit bud formation but also affects tree vigor. Therefore, it offers no promise for promoting annual bearing. Treating trees that are approaching bearing age but have little or no crop is quite likely to be follov/ed by a moderate to heavy crop the next year. It is a special practice for particular conditions and not to be generally recommended. It might be useful on filler trees or where one wishes to get fruit a year or two sooner than he would in the normal course of events. If done at the proper season there is little danger of loss or serious injury to the tree. j. K. Shaw ♦ -2- Irrigation of the New England Fruit Farm Large, arjiual yields of quality fruit are obtained \vhere moisture supply and necessary mineral elements are in proper balance. If a given acre of land can furnish only enough water during the growing season for a 100-bushel crop of apples, a larger yield is unlikely regardless of the fertilizer program. Heavy applications of nitrogen on a drouthy soil may, in the case of apples, encourage early dropping of the fruit, stippen or bitter pit, internal cork, etc. On a deep, well-drained, retentive soil enough v;ater is available to take care of the needs of a fruit tree even during a three or four weeks' drouth. This of course is not the case on a coarse, excessively-drained soil or where subsoil conditions prevent deep rooting. Irrigation is one means of supplementing rainfall on such handi- capped soils. It has been estimated that a mature apple tree may require as much as 4500 gallons of water during the growing season. If we consider 27 such trees grov;ing on an acre of land, the v/ater requirement for an entire season amoxmts to less than 5 acre-inches of rainfall. And since our average rain- fall in Massachusetts amounts to 3 or 4 inches per month, it is difficult to see why a shortage of moisture should occur. The fact is, of course, that only a small percentage of the water which falls as rain ever becomes avail- able to the tree. Much of our rainfall comes while the ground is frozen. In ma^y orchards, compact soil conditions or a scanty cover results in sur- face runoff instead of penetration to the soil zone occupied by the roots. In analyzing moisture relationships in an orchard we need only to compare the appearance and behavior of fruit trees with deep root systems on a fertile retentive soil with those on a drouthy, impoverished soil. Luxurious, dark green foliage with rapidly sizing fruit tj/pifies the normal tree. Here the cover crop seldom shows signs of drouth. In fact, a deep-rooted tree will thrive long after the cover crop shows drouth sjrmptoms, since it has access to vra.ter in the subsoil not available to shallower-rooted plants. In years past considerable stress has been placed upon elevation and slope in the location of an orchard, vAiile very little attention has been giv- en to soil type. As a result, orchards have been planted on all sorts of soils ranging from those that are too wet to those that are hopelessly over- drained. As an example of the latter type, the Hinckley soil series ought not to be considered for orchard purposes since the moisture supply is totally inadequate for good production. Orchards noxv planted on soils either too wet or too dry should be removed and such mistakes avoided in the future. Severe drouth sjonptoms in an orchard are easily detected. They manifest themselves in a slovdng up or actual stopping of the grov-iih of the fruit, yellowing and dropping of the leaves, and in severe cases, a drying up of the cover crop. A moderate shortage of water, however, is seldom de- tected. Only the observing grovrer will sense the demand for additional water before the shortage actually occurs. Here is where irrigation may prove highly beneficial. Without irrigation in a dry season, the fruit at harvest time is smaller, may drop prematurely, and may be affected by Baldwin spot or internal cork. Irrigation is now being used by a few Massachusetts fruit growers to supplement our annual rainfall, which averages 43.7 inches. In irrigated "(.:. :::■ 'i .-I . sections of the U. S. apples show a markedly improved color where the trees are given an adequate water supply throughout the season. If v.'ater is with- held at a critical time the color is dull and unattractive. During a dry- season about ten years ago, a block of large, heavily-laden apple trees in a Corjiecticut Valley orchard seemed to be functioning normally until mid-July v;hen the leaves began to take on a lighter shade, the fruit stopped growing, and the grass cover began to dry up. At harvest time few of the apples were over Zjj inches in size, the color v;as abnormally dull and the flavor v^as disappointing. After that disastrous season a simple irrigation system v/as installed and enough water supplied during subsequent drouths to insure a crop of at lee.st 300 bushels of good quality fruit per acre. Does Sawdust Tend to Acidify the Soil? R. Vi'. Donaldson, Extension Agronomist, has called to our attention the following report from Rhode Island Agr. Expt. Sta. 3ul . 251, "Comparative Tests of Bedding Material." Three plots of land have received annual appli- cations over a period of 18 years, as follov:s: (1) Manure and sawdust or shavings. (2) Manure and straw. (3) Chemical fertilizers. Equivalent amounts of lime have been applied to each plot. Sawdust or shavings v/ere applied to Plot 1 at the rate of 39 tons per acre, 25 tons having been applied in the last 9 years. Twenty-tv;o tons of straw were applied to Plot 2. These two plots have received 218 and 244 tons of manure respectively. Recent acidity tests show the pH of Plot 1 to be 6.5, Plot 2 almost exactly the same (6.49) while Plot 3 vrhich received the chemical fertilizer is very slightly over 7. These data offer convincing evidence that sa^vdust does not tend to acidify the soil more than straxv, v;hile the response of crops proves that it leaves no detrimental residue in the soil. Any fruit grower who may be hesitant about using sawdust as a mulch material for fear it may make the soil too acid, should take courage as a result of these tests in Rhode Island. Sawdust as a mulch material leaves much to be desired, since grass tends to grov/ through it so readily. It does, however, provide some of the desirable features of a mulch material, particularly in stabilizing moisture relations. The Farm Labor Situation in Ilassachusetts A 'ques'ti'onnarre"vms "recently sent to 600 farmers by R. E. Moser, Extension Economist. Replies were received from 194. Tvro-thirds of this number report that there is a shortage of farm labor in their tovms. A total of 723 men were employed by these farmers at the time of the survey. The average cash v;ages paid to these workers is $43.95 per month v;ith board. TiTorkers who are not boarded are paid an average of $79.91 per month. Wages paid per day are |1.84 v;ith board and ^3.04 without board. Eighty eight farmers lost a total of 174 workers. One hundred and thirty of these were lost to industry and 44 to military service. One hundred and forty seven men or one-fifth of the workers are still subject to military service. Of the 88 farm.ers v;ho lost workers 36 have not been able to replace them with nevr labor. Probably the best ansv.'er given so far to the labor situation is found in a report of the F;ural policy Sub-committee on Farm Organization and Practice prepared by Jonathan Davis. The principal items in the report are these: Massachusetts farmers are finding a shortage of farm labor which will -4- probably become more acute in the near future. The denand in industry for skilled, semi-skilled, or even unskilled labor at high -rages and short hours has lured aimy much of our available farm labor. The draft is also being keenly felt in many cases. The committee makes the following suggestions for farmers; (1) Hold on to skilled labor, if possible, as such men cannot be replaced at the present time. ~[2) Good farm labor should be and usually can be deferred by the draft board, if the "farmers will take pailis' to" COTTtact" The TocaTr dra"ft bo'ard~'oF Board of Appeals. (3) B_ettar inanagement or plaruiing to make full use of la- bor a^'ailable. Operations may of ten "be inc'reased or" decreased to fit the labor supply. (4) Father and son partnerships. This is an ideal situation where it is successful. In most cases of failure it is because the son is not given enough responsibility or direct interest in the enterprise. (5) Use of unskilled labor. Boys betvreen the ages of 14 and 21, still in school, are often good help during the surmer, Vv'omen and girls may be used to a greater extent, particularly on fruit and vegetable farms. (6) Use of part- tLme labor . Industrial workers on a 40-hour v/eek v;ill often be glad"To spend some of their spare time on the farm. Older men and others capable of hold- ing down regular jobs may often be used to advantage for a few days' work. (7) Increased use of machinery. This may not necessarily mean purchase of nevr equipment but bettor use of that on hand. A few days hire or swapping the use of machinery may often accomplish much at little cost. Blueberries in the United States The term "blueberry" includes several distinct tjqpes of berries which are less closely related than, for example, the various varieties of stravj-- berries or of apples. According to George !'. Barrow, pomologist in the United States Department of Agriculture, six tj'pes or species of blueberries are marketed extensively in the United States. The lowbush blueberry (Vacciniun angustif oliun) is the most import- ant commercial species ranging from Ilaine to Tinnesota and southward in the Alleghenies to West Virginia. The aianual value of the fruit harvested (only a small part is harvested) is probably m.ore than y 5 » 000, 000. The highbush blueberry (V. cer;;,'mbosum) is native from southern Ifaine to southern Michigan and southv.-ard to Georgia. The annual value of the crop from the v/ild ranges from $1,000,000 to ^1, 500, 000. It is from this species that the cultivated varieties of blueberries have come through years of selection and hybridiza- tion. The value of the 1938 cultivated crop v/as about 0400,000. Cultivated blueberries are raised comrnsrcially in relatively few states. The estimated acreage in 1939 v/as 1045 acres in Tew Jersey, 200 acres in North Carolina, 200 acres in liichigan, and 100 acres in all other states including liassachu- setts. The dryland blueberry (V. pallidum), "lov/ huckleberry," is important in northern Alabama and :feorgia, and northv/ard to Uaryland and l/est Virginia. The arjiual value of the crop is around ^300, 000. The evergreen blueberry (V, ovatum) is native on the Pacific Coast from centraTT California to British Columbia. The annual value of the fruit crop is estimated at close to $200,000. Furthermore, its branches are of about equal comm.ercial value for decorative purposes, being shipped to eastern cities as "evergreen huckleberry." The mountain blueberry (V. membranaceum) is a native of the high slopes of the Cas'c'ade Tlountains (Oregon and Yi'ashington) and eastward tovm.rd IVisconsin. The berries are very large and high in quality. y' -5- The value of the crop may average |200,000. The rabbiteye blueberry (V. vir- gatum) is native in southern Georgia and Alabama and in northern Florida. Commercial fields totaling about 3,500 acres are operated in these and other southern states. All of these species are true blueberries as distinguished from huckleberries which have 10 large hard seeds. Blueberries have many very small, soft seeds, L. Southv/ick How Far V/ill Apple Scab Spores Travel? The following report helps to explain the appearance of apple scab on the leaves of newly planted trees where no scab was present the previous season, and the partial failure of "orchard floor" spraying. D. H. Palmiter of the New York State Research Laboratory in the Hudson Valley, says that in 1940 at the time of the first scab spray in the Hudson Valley (delayed dormant) scab spores were not far enough advanced in the old leaves on the ground to justify a fungicide, and no spraying v;as done at the time for protection against apple scab. In Western New York, on the other hand, scab spores v/ere mature at the corresponding stage of tree development. A general rain storm occurred over the state at that time ivith a strong wind blowing east- ward. Later in the season a general light primary infection of scab shovred up in the Hudson Valley that could be assigned to that particular v;et period, in spite of the fact that scab spores \vere not yet mature in the Hudson Val- ley when the rain occurred. It was concluded that the infection resulted from spores blovm from the 'jYestem part of the State over a distance of more than 100 miles. 0. C. Boyd Application of Soap for Red ilite Control Recent tests have shown that soap (hard, fishoil, or flakes) at a dosage furnishing the equivalent of 4 pounds of dry soap to 100 gallons has shown promise against red mite but also appears to be toxic to some of the red mite predators. If the agitator is disconnected when the spray is being prepared, the danger of formation of troublesome foam or s\ids v;ill be lessened. A. I. Bourne Apple Crates^ "A" - "B" - "C" . V'.'. E. Piper of the Division of Markets has recently released a sum- mary covering the apple box situation in the Northeast. For purposes of easy identification the three most discussed crates may be designated by the letters A, B, and C, the dimensions of which are as follows: A Regular 1 l/5 bushel - 17" x 14" x 11" B 1 1/8 bushel - refrigerator car size - 16" x 13 5/8" x 11 l/S" C 1 l/8 bushel - 17" x 13" x 11" Mr. Piper finds that most apple growers exhibit a decided preference for the 1 l/S bushel crate of the refrigerator car size (B^ crate). As to what will be actually used, hov/ever, the preponderai-ice of opinion leans rather definitely to the 1 l/5 bushel (A crate). The difference between what is preferred and what will be used lies in the fact that a great many growers want to use the 1 l/S size, but feel that it is useless to tie up with it as long as they vrould be in competition with the larger 1 l/5 size. This might be best expressed in tlie words of a large Massachusetts shipper, who says, "I believe in sticking to the A crate until it is outlav/ed the same as the 14 qt. bucket. Gtlicr states arc using bulge packs with plenty of weight for competition." Classified by sections, the replies indicate prevailing sentiment as to what will be used as follows: Eastern Massachusetts A large majority of those reporting saj*- they vrill use the A size, although several large operators are buying the E crate, and a few talk of the C size. Central Massachusetts A size very strongly in lead. Vv'estern Massachusetts More evenly divided between A and B than the other parts of Massachusetts, New Hampshire About same as eastern Massachusetts. A crate much in lead, but few will use other two sizes. Maine Very strong for A crate. Vermont Opin- ion divided between A and B. Connecticut Pretty well split up between A and B; also some for C. Rhode Island Mostly for A. Hudson Valley Many large growers say A, but there is considerable sentiment in favor of B size. Western New York Majority for B size, few for A. The Vitamins — Functions and Food Sources Some definite information on a much discussed subject has recently been summarized by Gladys M. Cook, Resident Instructor, and May E. Foley, Extension Nutritionist, at the State College. Tv/o questions are first an- swered: Q. What are vitamins? A. They are powerful substances v.'hich occur in very small quantities in foods, but must be available to the body for grovrth, maintenance, and health. Q. Is it possible to get too many vitamins? A. It is not possible to get too many even in foods chosen definitely for their high vitamin content. It is v/ell to choose a diet which far exceeds in vitamin content the minimum requirements, (in the following outline wherever fruits and vegetables constitute a food source, they are underscored.)

Effect of Cooking, Drying, Air, Storage, and Freezing Upon the Vitamins A Not easily destroyed. Bl This vitamin may be lost to a serious extent mechanically in refining the food, or by discarding the water in which foods are cooked. Long cooking, high temperatures, and the use of soda in cooking water are very destructive. C Easily destroyed by cooking - (especially in the presence of air and alkalis), in drying, storage.

Here's an Idea Have you ever observed the performance of a fruit tree grov/ing next to a large shade tree? The outside row of an orchard adjacent to forest trees may offer a good example. Or if you prefer, let's consider the apple or peach trees which have as their nearest neighbor a widespreading oak or maple which was left bj'' the previous owner of the farm to provide shade for his cows. Fruit trees under these conditions are likely to be somewhat smaller, the yield is lower, and in extreme oases branches of the fruit tree are tilted away from the shade tree as it shuns the shade of its towering neighbor. Sev- eral apple trees in the College orchard where yield records have been kept over a period of years offer a good example of competition below and above ground. If the competition between a maple tree and an apple tree is so ap- parent, how about the competition between two apple trees growing side by side, each attempting to exploit the same soil and avail itself of sunlight over the same area? Let's take, for example, an apple orchard of well grown trees 25 years of age v;ith 54 trees to the acre (40x40 with a tree in the middle of the square). Each tree must of necessity exert a detrimental influence on the trees adjacent. If we measure yields on a tree basis each individual tree is failing to give as good an account of itself as would be the case if it had unlimited light and unlimited soil. YiTienever we hear of an apple tree yielding 50 or 60 bushels annually w^e may be sure that the tree in question is standing by itself and therefore has undisputed claim tc the sunlight on all sides. ' The point we want to convey is briefly this: The extra trees in the orchard exert much the sai.ie influence on adjacent trees as is exerted by adjacent shade trees. We can't always eliminate the competition of these giants of the forest. But vte can make sure that the spacing in the orchard provides each tree xvith enough soil and light to bring about efficient pro- duction of fruit.

J FRUIT NOTES - JUNE, 1941 •I. H. Thies Extension Horticulturist Popularity of Cortland Increasing In a r'ecent' evaluation of apple varieties in the Nortiieastern States, Cortland stood second to Mcintosh. There are two principal reasons why Cort- land has been rather slow in gaining popularity. One is a lack of demand in the markets and the other is its tendency to scald. The former is being over- come as the variety becomes better knovm. Recent experiments carried on at Cornell give some suggestions for tlie control of scald. Scald is associated with immaturity of tlie fruit; it is worse on the larger apples and decreases with increasing age of the tree. Suggestions for decreasing scald are: Plent_ of nitrogen to hold the leaves late in the fall, so that carbohydrate production may be greater, wide spacing of the trees and judicious pruning to give the leaves more sunlight, and spot picking. In years of light rainfall and ample sunlight in the latter part of the season, Cortland may be stored longer than in wet seasons with subnormal sunlight. Cortland sticks vrell to tlie tree and may be allowed to hang until well matured. J. K. Shaw I/i^'t Baldwin Bloom and a Possible Reason " \Ve hea? reports' o'f a light bloom on Baldwin trees throughout the state this year. According to our records, this variety also bloomed lightly in the College Orchard in 1932 when it could not have been due to frost or cold injury, but must have been caused by subnormal fruit bud formation in 1931. Vieather is ail important x'actor in the production of fruit buds. The unusual v/eather fac- tor in the spring of 1931 v.'hile the stage was being set for fruit bud formation was excessive rainfall. Much the same condition prevailed in 1940. Rainfall during the spring of 1931 and of 1940 was as follov/s: April H^Z June Excess during April, May & June - .40 43.84 + .49 +3.93 +3.02 +2.07 -1,29 +3.80 3.35 3.60 3,75 1931 Excess or Deficiency 1940 " " " Normal Rainfall, inches 7Jhether and why excessive rainfall previous to fruit bud differentia- tion should be detrimental to fruit bud formation is problematical. It would not only wash nitrates out of the soil but also would interfere with absorption of nutrients, especially on poorly aerated soils. This would reduce leaf area and check fruit bud formation. The excessive rainfall in these two springs may be a cause of light bloom of Baldvdns or it may be only an interesting coinci- dence. J. K. Shaw Clovers and Hay Mulch in the Orchard Last summer vfe seeded one of our orchards to a mixture of red, alsike, and Ladino clovers and obtained a good stand, Alsike and red clovers naturally predominate, but there are many plants of Ladino clover aiid it may be expected to increase. The trees in clover are growing well and the leaves show good color, but trees in the same orchard where mulch was applied on a cultivated -2- soil, are also looking well. The soil under the mulch is loose and well aerated. There are many apple rootlets in this layer of loose soil. They have been at- tracted either by better aeration, more moisture, or more nutrients, or by all three. Evidently, earlier benefits may be expected from mulch applied to bare soil than vihen put on a grass sod. ?ve are seeding two or three acres to mulch producing crops to see if it is practical to grow mulching material outside the orchard. J. K. Shaw Internal Cork and Dry Siimmers A recent paper by L. P. Latimer of New Hampshire gives data shov/ing the relation betv;een drouth and the appearance of internal cork in apples. He finds that the one contributing atmospheric factor definitely responsible for the inability of the tree to get enough boron for perfect development of the fruit is extended drouth during June and July. This is in harmony with our observations in Massachusetts. Growers have the option of sending for the Rainmaker or using boron in their orchards. J. K. Shaw A Not e on Boron Deficiency In British Columbia it has been found that applications of boron for preventing internal cork are best made in late summer or early fall. Growers in Massachusetts who have apple blocks in which this trouble has appeared should apply borax at the rate of about 1 ounce per inch of trunk diameter. One pound of borax is ample for even a large tree. A ring application is recommended owing to the difficulty of broadcasting so small an amount, 30 pounds per acre, in a way that will insure each tree getting its full share. Although apple trees are less sensitive to boron poisoning thsin most other plants, there is some danger in overfertilizing with borax. A single borax treatment will apparently last at least three years after which it may be necessary to repeat the application* J. K. Shaw An Experiment in Vertical Drainage Farmers often ask about the possibilities of subsoil blasting as a means of draining wet spots in fields or orchards. An experiment just com- pleted in Delaware throws some light on this question. The soil profile in the one acre wet spot under consideration showed a loam top soil 15 inches deep,, a white clay subsoil 6 feet deep, and a sandy gravel below that. On August 1, 1937, twelve holes were made with a 2-inch soil auger on 30 foot centers, 8 to 10 feet deep. Four pounds of dynamite were loaded in each hole in vertical columns v;ith at least 18 inches of dirt tamped on top of each load. Vihen the shots were fired very little soil v;as blown into the air, and few craters appeared. After each rain vertical drain- age in the area was found sufficient to protect field crope. The final step, taken December 1, 1937, was to dig a 10-inch hole, 8 feet deep at the point of each blast. This was comparatively easy because the soil vfas well broken. Six-inch drain tile vfas set vertically in each hole, and held in place by packing with sand, which acts as a filter to keep out clay particles. Each tile column was capped 15 inches below the surface to protect it from cultivating tools. In June, 1940 an inspection of this area showed that drainage was 90^ satisfactory. Materials required to drain this one acre spot were 50 pounds of -3- d\T.amite, 100 feet of 6-inch drain tile and 12 concrete tile caps. The procedure recoramended tc determine whether subsoil drainage is feasible is as follows: Hake a soil profile at the wet spot showing (1) deoth of top soil, (2) depth of impervious subsoil, and (3) depth of sand, gravel or water-carrying strata, if any. If the water-carrying stratum is close enough to the surface to indicate that blasting v/ill remedy the wet condition, there still remain., the question of whether the water-carrying stratum can take care of the additional surface v.-ater drained into it during periods of heavy rain- fall. Since there is no economical way to determine this in advance, the only answer is to try it out. It has been found that if sand or gravel lies within 10 feet of the surface, the Irnd ovmer has better than a bO-50 chance of getting satisfactory vertical drainage by blasting with dynamite. Do You Knovr That peach and apricot trees in the South often fail to leaf out or bloom until almost midsumjTitr because of too little cold vreather during the ■"/inter months to break the "rest period?" That leafhoppers have been found to decrease photosynthesis of apple leaves almost 25%J Under these conditions size and quality of fruit are likely to suffer. That an electric fence 62 miles in length has been erected in Florida to protect crops against deer? This barrier is a 6-strand barbed wire fence about 7 feet high and extends from La'ce Okeechobee to Fort Myers. That the so-called Gloucester scries of soils covers a greater area in Massachusetts than any other? The total percentage of our land area covered by the five most common t:>rpes is as follows: Gloucester - 20.63^, Hinckley - 6.58^, Carver - Z.d7%, Coloma - 3.16^, Charlton - 2.83^. That the tolerance on arsenic and on lead, established by the Fool and Drug Administration, has been changed five times since 1928? The tolerance on arsenic that year was .03 grains per pound, in 1929, .02;j; 1930, .02; 1931, .012; 1932-1939, .01, and 1940, .02C. The tolerance on lead is now just twice that amount, .05 grains per pound. That a pollen grain under favorable conditions will germinate within 30 minutes a-^ter it reaches the stigma of the blossom? If the temperature is favorable, many pollen tubes mav traverse the style of the apple and plum within 48 hours. These sta.tements are laade in a new textbook by Gourley ft ilowlett, "Modern t^riiit Produeticn." That there are ".t least 10 times as many 1:|- to Ig-" peaches in a bushel as there are of 3 to 3-^-" peache;>? The numbers of peaches of different sizes in ^ 50-pound bushel are apriroxir.ately as follov.s: 1^ to Ig-" , 960; Ig- to 1 3/4", 611; 1 S/TT^V^ 340; 2' to 2^", 250; 2-|- to 2^", 195; 2-^- to 2 3/4", 140; 2 3/4 to 3", 110; 5 to 3p', 90.

That the length of the wetting period required for a light infection of scab on apple leaves varies from 9 to 20 hours, dependent upon air tempera- ture at the time the infection occurs? The following table, arranged by TJ^, D. Mills of Cornell University, shows the relationship between temperature, length of vretting period, and degree of infection. These data assume a condition where mature scab spores are abundant.

Hewlett Quality of Apples from Modified Atmosphere Storage Although qu'ality in fruit iVa difficult thing to measure, everyone who sampled apples from the modified storage room at the Si>ate College and com- pared them with apples from ordinary cold storage agrees that modified storage apples have a better flavor. Even though the oxygen content of the storage room was higher than it should have been (10?^ instead of 2%) the ripening pro- cess during the winter was slowed up enough to produce a Mcintosh of better - . . quality in April thaji was possible in ordinary storage. In freshman chemistry class vie learned that an oxidizable material burns faster in an atmosphere of purf oxygen than it does in ordinary' air. The ripening process v;hich goes on inside an apple might be likened to burning since it involves the intake of oxygen and the giving off of carbon dioxide. If only a limited amount of oxygen is avail- able, the ripening process goes on more slowly. This seems to be one of the advantages of the modified storage. Fire in the Orchard Many more orchard fires have been reported this spring than in some years past. The majority of these fires have been started carelessly although occasionally we find someone who is so shortsighted as to burn over the orchard floor every spring. Y'e do not recall ever seeing a highly successful orchard v/hich has received this kind of treatment regularly. In the minds of some grov;ers burning over the orchard floor is sup- posed to simplify the pest control program by destroying insects of various kinds and also scabby leaves. In reality, the loss of mulch material probably offsets any possible value from the standpoint of pest control. If, as many of us believe, it is a good policy to stim.ulate groi-vth of vegetation in the orchard and also to haul in additional mulch, then it seems the height of folly to burn this important asset. Some individuals imagine they are accomplishing an im- portant task when they touch a match to the dry grass in an orchard. Here is a chance to make a tremendous showing for a small amount of effort. But for every acre burned over it is reasonable to assume that at least five or ten dollars worth of mulch material goes up in smoke to say nothing of possible damage to the trees. From the standpoint of the trees, tlie damage depends to a large extent upon the thickness of the bark and the amount of dry material adjacent to the trunk. One of the v;orst cases of damage observed this spring is in a 7-year-old orchard of vrell grovrn trees v.'here the soil had grown perhaps two tons of hay per acre for a number of years and this had been crrefully placed around the trees. Obviously the results were disastrous. The experience of this spring, however, should not deter the fruit grower from using mulch material in the orchard. It is entirely possible to mulch heavily without incurring a ^reat fire risk. A heavy mulch, Vv-ell packed down around the tree, and not too close to the trunk, seems to be less menacing from the standpoint of fire than a heavy growth of grass left uncut. One of the best v;ays of safeguarding the orchard is to clean up adjacent brush and trash. A fire break in the form of a few furrows around the orchard may sometimes be desirable. An unusual case of fire damage was reported this spring where the exhaust from a tractor result- ed in a blaze where an inflammable fertilizer material had been scattered liber- ally over a dry mulch. Control of Oriental Fruit iiota by ;.Iechanical Lieans Recent p+'i'Ji.jS in Indiana show some interesting results in the control of Oriental fruit moth by removal of infested tv.dgs and fruits. This practice must be carried out at short intervals beginning early in the season to prevent a high infestation at harvest time. It is rather common in Europe and Asia but has been little recommended in the United States. The principal objections are that such a control practice involves too much tedious labor and that tlie repro- ductive possibilities of the insect are so great as to preclude any hope of suc- cess. The Indiana orchard selected for study showed an infestation of approx- imately 25^.' in 1935 before infested tv;igs were collected. In 1956 there was ne* -6- crop. In 1937 the averare infestation \vas G.l^j with only 2.6>c visible infesta- tion. In 1938 the visible infestation w&s 1,5^'. In 1939 clipping vms carried on until the middle of June when the number of infested twigs became so small that the grower decided it would not pay to continue the practice. At harvest time, August 25, the infestation in this orchard had built up until it averaged 13% of the crop. The cost of collecting infested tv.dgs amounted to 5/ per bush- el of harvested fruit. But the resulting fruit was enough better to increase the price by 16 5/4/ per bushel, thus netting a good profit on the investment. On the basis of these tests the following observations have been made: (1) The orchard should be' isolated from other peach and apple plantings. (2) v:hen attempting control by the removal and destruction of the infested twigs and fruits care must be exercised to see that no trees are left untreated, (3) The later the peach variety the greater the number of times the orchard will have to be looked over. (4) Seasonal conditions often cause considerable difference in the population of Oriental fruit r.ioth. (5) Twig clipping should be started early, the entire orchard wor)ced over at least every five days, and the work continued until less than a month before harvest. (6) Usually more attention should be given to border rovrs of trees than those in the middle of the planting. (7) All infested twigs and fruits should be removed each time. All dead and dying twigs should be removed thus simplifying later examination. (8) Tree height should be controlled so that all infested twigs can be reached from the ground with the aid of a short hook. Control by this method reduces to a minimum brov.-n rot and the necessity of sprays to control this disease. (10) Debris should be kept cleaned up around the trees. Roadside stands and packing houses should be kept screened until after the spring emergence is over. (11) Because of the larval habit of going from one twig to the other at least tv/ice as many twigs will be removed as larvae. (12) Vfhere conditions make pos- sible the adoption of this method, and if the work is efficiently done, clipping of infested tvdgs will yield a reasonable return on the investment. A Long Lived Peach Tree Stressing the Importance of armual pruning of peach trees, A. J. Down- ing in his book, "Fruit Trees of America," published in 1872, says he has seen two peach trees of the same age side by side, one unpruned and the other regu- larly shortened- in and both bearing about four bushels. The fruit of the latter, hov/ever, was double the size and incomparably finer. He attributes the old age of certain antiquated peach trees in France to the annual pruning which they received. Referring to a tree near Villeneuve de Roi, he writes, "The tree is trained against one of the v/ings of the mansion, covers a large space and the circumference of the trunk taken at some distance from the ground is 2-^- feet. It is knorm to be actually of 93 years' grov>'th and is believed to be more than 100 years old. It is still in perfect health and vigor. It is growing in strong soil but it has been regularly subjected to a uniform and severe syst'^m of pruning, equiimlr-nt to our shortening-in system. VCiere can any peach ti'ct of half this age be found in the United States, naturally a much more favorable climate for it than that of France?" Citrus Fruits are Standardized, Hovr About Apples? In the February 15 Consumers' Guide reference is made to the fact that the Federal Food and Drug Administration patrols the citrus fruit industry and sees to it that only mature fruit is sold in interstate commerce. In the past, after freezes or frosts the Federal P'ood and Drug Administration has seized some citrus fruits. At the present time there are no official compulsory fed- -7- eral standards for citrus fruits but it is likely that such standards v/ill be established in the near future under the authority of the Federal Food, Drug Emd Cosmetic Act of 1938. Unofficial standards which were used as a guide before the passage of new Food, Drug and Cosmetic Act requires grapefruit to contain 7 parts of soluble solids (which is roughly sugar) for each part of acid. Oranges had to contain 8 parts of soluble solids to one part of acid. At. interesting story from Australia appears in a recent issue of the Rural New Yorker. "Australians have shown the way to American producers v.'ho are interested in seeing that proper standards are maintained for the fast grov.'ing fruit juice industry. The Australian Apple and Pear Board proposes to issue sealed certificates tc manufacturers whose goods are analyzed and come up to the required standards. The Board will receive the cooperation of the Council for Scientific and Industrial Research which will examine all juices submitted and issue seals. If a product once approved fails to maintain the required standards the certificate is v/ithdrawn. Publicity is to be under- taken to acquaint the public ivith the reliability and availability of the sealed products." This is a step in the right direction. There is too much poor apple juice on the market. American packers and producers should get to- gether and set up some scheme of standardization and certification of their own. Standards for apple juice are now being developed by tlie Eastern Apple Research Laboratory in Philadelphia under the supervision of J. J. Vrillaman. Semidwarf Apple Trees Doing V.^ell Our oldest apple trees en semidwarfing stocks in the College orchard are now in their fourteenth year. They are about 12 feet tall and behave as though they wrere not going much higher. The Mcintosh trees yielded about 3 bu. per tree in their fifth year, and in their thirteenth year produced nearly 10 bu. per tree. This type of tree should be planted 25 or 30 feet apart. Per acre yields promise to be greater than that of standard trees. They re- quire a reasonably fertile soil and good fertilization. At the present time we have several cooperative orchards of these semidv/arfing trees started v.dth Massachusetts fruit grov/ers. If there are other growers interested in such trees v.^e wdll be glad to hear from them by July 1 so that, in event of satis- factory arrangements, we can bud the necessary trees during August, to be set in the spring of 1943 or 1944. J. K. Shaw New Strawberry Varieties Three new strawberries have been named by the U. S., namely, Maytime, Starbright and Redstar. Maytime is introduced as the earliest variety of high quality in Maryland, originated as a cross between Missionary and Fairfax. Starbright is introduced for trial as a midseason commercial and home garden variety "of great beauty," originated from a cross between Chesapeake and Fairfax. Redstar is introduced as a very late, firm, commercial and home- garden variety "of exceptional beauty," originated from a cross between Chesa- peake and Fairfax.

FRUIT NOTES - July, 1941 W. H. Thies Extension Horticulturist Arkansas Picka Michigan Strawberries On a recent trip to ilichigan I visited the large fruit farm of Stanley and Glenn Geisler at l.'atervliet, Michigan, Besides peaches and apples these brothers have twenty acres of strav.'berries. Vv'ith so many strav/terries hand labor is avoided as much as possible but picking, of course, still has to be done by hand. Last spring the labor situation looked rt.thcr desperate and the Geislers wondered ho\'i'^ they would ever get twenty acres of strawberries picked. But as the picking season drew near, the pickers began to roll in, whole families of them. They csme in jalopies, in trucks, and in cars. They pitched their tents, parked their trailers, or cccupiod \-arious temporary shelters. Pickers viere plentiful and things looked brighter. These pickers are an interesting group 7;hose home is Arkansas. They start with the crop in Louisiana and move north as the crop moves north. One family had an old Model T Ford -.vith no radiator cap and the steam poured out like a steam engine. Oth'^rs had the letcst model cars pulling expensive look- ing up-to-date trailers, Anoth>-r interesting feature of the Geisler' s strawberry business is their irrigation system. They have ai: eighty foot well with a deep well pvimp driven by a Buick motor. The water is carried to the fields in light, four-inch sectional steel pipes and distributed by a sprinkler system at the rato of about 150 gallons pr,r minute. I\ii irrigation the first of June saved their crop this year. J. S. Bailey The Farm Labor Situation The bimonthly survey of i;he farm labor situation in Massachusetts has Just been completed. One hundred and sixty-three farmers in all parts of the State cooperated in this survey. The farm labor situation has become more stri6us since the first of April. A larger percentage of farmers lost workers during April and May and v.'agcs per month v;ere about ^2.39 higher than they were on the first of April. A considerably larger percentage of farmers report that they were not able to replace workers that ^vero lor.t. Mtuay of those v'ho report that they were able to replace the workers who were lost, can do so only v/ith inexper- ienced help and in some cases only v.dth loj's. Many of the farmers report that they cannot get the necessary sei.scnal cr day labor this year. Of the farm workers viho were lo.st during April and May, 115 v/ent to jobs in industry, 12 were taken by the /nilitary service and 33 "went to work on other farms. Of the 900 men employed on these farms at present, 149 are of military age and may be subject to military service. It is encouraging to note that only 12 men were taken by the military servico during these two months. This is tangible evidence of the excellent cooperation of the Selective Service Boards v/ith the farmers in these difficult times. -2- Ei£;hty-four farT.ers will need extra help in June a:id July and the reported need is 2.87 workers. Ninety-four of these are needed on vegetable farms, 67 on farms rhere livestock is raised, 37 on poultry farms and 25 each on dairy and fruit farms, 21 on diversified livestock farms and 18 where only crops are produced. The labor situation is serious on all types of farms 'but at the present time it seems to be most serious on dairy farms or where the dairy-crop combination of farming is carried on. Farmers are meeting the labor situation in various ways: 30^^ by re- ducing farm operations, 25^ by shifting to other crops v/hich require less la- bor and 32/^ have bou£h-c new machinery. Seventy percent of the farmers re- gard the situation as serious at the present time and 8i% feel that it v.-ill become more serious during the summer. The Massachusetts State Employment Service is cooperating in every way possible in ivorking out the farm labor problem. They have registered over 5500 school boys who are willing to work on farms. In April, the Ser- vice placed 152 agricultural v;orkers throughout the State and 107 during the month of L'ay, The Employment Service csui and will render valuable help through its 35 offices in the State, It is very important that farmers make their labor needs known to the Employment Service as early as possible. This is particularly true for fruit grovrers, market gardeners and cranberry growers where a relatively large quantity of labor is needed. Growers should contact the manager of their local employment office now and tell him exactly what their needs are. He will then do his best to provide workers. Your county agent has a list of the employment offices in the State. The services of these offices are free to both the farmers and the farm workers, R, E. Moser Fruit for the Soldier This summer the United States must be prepared to feed an army of about one and one-half million men. This is a consuming unit comparable in size to the city of Detroit. This vast army is scattered around the country in a nuffiber of separate posts. Instead of having to feed the city of Detroit, it means the task rof feeding 30 or more cities of the size of Kalamazoo, Michigan. Translated into dollars, the increase in the army size means the Government will spend at the rate of about •'^■235,000,000 a year to feed its soldiers. Approximately v35,000,000 will be spent for fresh fruits and ve- getables. This amounts to nearly C'100,000 every day for fresh produce. Men in our army are apparently eating more apples per capita than civilians. The same is probably true of many other fruits and vegetables. In other \vords, the soldiers in the United States are enjoying a far better diet than in some other countries in the v;orld. In Germany, for example, it is v;ell known that not only fats but fruits and vegetables are needed to main- tain national efficiency and restore vitsanins and minerals lost in two years of unbalanced diet. The importance of the fruit industry in national defense is brought out in a recent editorial in the Aiicrican Fruit Grower, The edi- torial contains this statement: "For the want of fruit, Germany may lose the war. Orchards of America are needed to keep our military man power effi- cient and active and to develop the health and strength of the great body of American youth being trained for military service," IVe must not, of course, limit ourselves to the products of the orchard. Small fruits and vegetables -3- occupy a prominent place in the Nation's diot. In the May issue of Fruit Notes you may have read of the foods vjhicl' supply various vitanins. V.'hat v.'e need is not vitamins in capsule form tut in those "sunshine capsules" which nay be produced on e^rery farm and in every backyard garden in the country. Farmers Exempt from Social Security and Unemployment Taxes j^j^j^ Ri^(r~f I'feT'lboro submi-cs the following item from the July Farm Journal and Farraer's YCife, "Forced to pay social security and unemploj-Tnent taxes v;hlch the law exempts farmers from paying, Gaylord Gut-rnsey Farms, Oklahoma City, Oklahoma, paid under protest and filed claims for refunds. The claims denied, suit was filed and the federal district court has ruled in favor of tiie farm. The Internal Revenue Department claimed the farm should pay taxes on a showman employed three months to take care of the show herd at fairs, also on a carpenter v:ho repaired buildings, a bookkeeper, and four or five truck driver salesmen who delivered and sold i.iilk. The court ruled all these were exempt. First case of its kind." Quoting from Mr. Rice's letter "Crchardists have been told that clerks on fruit stations and all who work on buildings like carpenters are subject to social security and unemplo^Tnent deduction. The U. 3. Court has just decided that any employee in an agricultural enterprise and the employer are exempt v/h ether working on or off the farm." Here's an Idea Why not employ women to harvf- st the New England apple crop? This idea also comes from John Rice of Marlboro. V.'e approve heartily of the idea. 'It. Rice points out that orchardists in California, Texas, and Florida are employing women very successfully in harvesting citrus fruits. In his own case he has m.ade arrangements to employ two crev/s of women with v;omen super- visors. It is suggested that interested growers publicize this matter in lo- cal papers with the idea of supplementing the meager supply of farm labor v/hich will be available at harvest time. It is estimated that at least 3,000 additional workers vail be needed this fall to harvest the Massachusetts apple crop. Lime Penetration „ ~''""'l,Iu7t*' lime be harrowed or plowed in to be beneficial? The follow- ing statement laade by A. B. Bcauiaont in the Hay issue of The Soil Auger throv;s considerable light on this question: "Observations of the lasting beneficial effect£3 of surface applications of lime probably account largely for the prevailing belief that this soil supplement does not penetrate the subsoil v^hen applied as a top dressing. Some research has shoxvm that lime penetrates soil comparatively slowly. The texture and porosity of the soil appear to be important factors in this corj-.ection, penetration being slower with the heavier, than the lighter, soils. The data below throw some light on the question of penetration of line :nto a fine sandy loaia, the predomi- nant texture of Massachusetts soils, as measured by the reaction of the soil at di.^'ferent depths. In the spring of 1924 lime was applied as top dressing in two rates tc certain plots used in a pasture experiment. In the fall of 1940, 16-^ years later, samples of soil from these plots were tested for reaction. The results are as follo\vs: Depth at V. rhich sample v/as taken Inche IS 0 - 4 4 - 8 8 - 12 12 - 16 16 - 20 20 - 24 Limesi bone appl led 1924 Pounds per acre No lime 3480 10360 4.5 pH 5.6 p!I 6.9 pH 4.7 5.1 6.6 4.7 5.3 6.0 b.l 5.6 5.6 5.3 5.6 e.i 5.5 5.8 5.9 The figures show, first, that the surface application of lime has affected the reaction of the soil to a depth of 20 to 24 inclics at least. It is not laiown how much deeper an effect was produced because deeper samples were not talcen. Second, the lasting effect of the lime is shov.Ti, For practical purposes, a^top-dressing ■' application to Massachusetts untilled grasslands of 1 to 1^ tons/lime every 3 to 5 years, continued until reaction of the soil reaches pH 6.0 to 6,5 to a depth of 8 inches, should prove satisfactory; after that, the reaction may be expected to be maintained by an application of 1 ton of lime every 5 to 10 years. For tilled land it is preferable to work the soil through the ploi-red layer by means of plov; and harrow. More About Poor Orchard Soils IVorkers at the Cornell Experiment Station have been leaders in re- minding us of something we have alv;ays knovm, that some soils are better for apple trees than others. Moreover, thoy hove told us more than we kncv; be- fore about good and poor orchard soils. A recent publication gives facts concerning yields and returns from various orchards in v;estern Nev/ York as shown below. The soils are rated from 1, (best) to 6, (poorest). 1 2 3 4 5 6 171 136 tl45 195 105 $86 75 71 $50 57 $38 Bushels per acre Receipts per acre Moral — Get rid of unprofitable orchards on the poorest soils and see that new plantings are made only on the best orchard soils. The same publication gives some interesting information on the use of spray materials, Tv/enty-five years ago the expense of spray materials per acre vras almost as much for orchards on poor soil as for those on good soils. Now it is over four times as much for orchards on good soils. The expense per vlOO of fruit receipts, however, is no greater on the good or- chards because of higher yields. Expense of spraying the good orchards has increased about four fold in the last 25 years. With increasing costs of spraying and management, the Io'vY producing orchard on a poor soil is in- creasingly at a disadvantage. J, K. Shaw Profits in Ve stern Fruit Folks often ask "How can V.'cstcrn fruit men stay in business, con- sidering the lev; prices which they receive for fruit?" The Rural New Yorker presents this explanation based on figures in Better Fruit. "Tshen yields of apples £s.re 350 boxes ner acre and the selling price is ^1 a box, there is a loss of $20.50, but ^vhen the ;'ield is 700 boxes, the proi'it is (172. At 900 boxes the profit is Si-SSS. An average crop in '^enatchee on full-bearing, heulthy trees is j;;iven in the neighborhood of 700 boxes per acre. If, now, the price is increased from v'l a box to s,1.25 the profit per acre on a JOO-box crop is v£07. Or, shovdng the results in a different way, the cost per box for a 350-box crop is vl^OG, for a 400-box crop it is 99 cents, for a 500-box crop it is 38 cents, for a 500-box crop it is 80 cents, for a 700-box crop it is 75 cents, for a 800-tox crop it is 72 cents, and for a SOO-box crop it is 69 cents. Profits on sweet cherries are reckoned at "sero" when cherries are sold at 6 cents a pound and when the yield per acre is 1 5/4 tons, but they reach *542.50 when the ;deld is 7 tons. Even at £ cents a pound the pro- fit is v402.50 on a 7-ton crop, v,1-iereas there is a loss of i,3£ on a 1 3/4- ton crop. Peaches and apricots shov; similar relations, with a profit of C2.80 per acre on a 10.8-ton crop sold at v20 a ton, and a profit of C432 on a 21.6- ton crop at the same price per ton. V/hen the price goes to v60 a ton the pro- fit fro:;: the 21,6-ton crop may reach vi,33G.

Fews , "Brovm Rot of the peach is favored by too closely planted trees, by a site v;here air circu- lation is poor, because of dense hedge rov;s or woods too close to the or- chard, by an air pocket fonned by higher surrounding land, and by a tall growth of weeds during the growing season."

It can be used for cutting citrus fruits w ithout fear of corrosion. Blade and handle are moulded in one piece. That the Stamp Plan started experimentally in Rochester, New York in May, 1939 had been extended by late 1940 to some 275 areas throughout the United States and was reaching several million persons in needy families? It is said that if every family in the country making less than ilOO a month ate as much as families which do make $100 a month, it vrould add two billion dollars a year to the Nation's food bill. Thirty to thirty five million acres of land v;ould be required to produce tliat extra food. That's an area f^bout the size of the state of Iowa, That largo amounts of available potash are being found under a hoavT,- mulch even to a depth of two or three feet? Quoting from a recent Potash News Letter, "Recent experiments show that favorable response of fruit plants under heavy mulch is due to improved moisture relations, better supply of nutrients, and of equal Importance, a better supply of readily available potash. Studies on raspberry plants at Bcltsville, Md. by Darrow and Llagness showed a much greater cane grov^th and five times as large yields under the mulch as in the cultivated plots. Determinations of the potash content of leaves from mulch and cultivated plants shovred 2,39/d and ^Q&'^o respectively." That there may be onl;- onc-fil'tu as many blueberries of certain cultivated varieties in a quart as there are of vv-ild blueberries? In a re- cent federal publication (Circ. 583), "Atlantic, Pomberton ajid Burlington Blueberries", mention is made of a sample of wild high bush blueberries bought from a roadside stand v.iiich had 384 berries to a \ pint cup. The same cup held 184 berries of the Rubel variety, 100 of Jersey (largest variety v/idely grown), 82 of Pemborton and 73 of Atlantic. That v^estern New York growers are talcing steps to prevent un- necessary bruising of apples? A coimnittec on harvesting and packing practices -7- inakes these recommendations: (l) Follow spray practices which v,'ill eliminate the necessity of washing or brushing the fruit, (2) Pick the fruit carefully in rig-id containers, employing;; pickers on a timo basis, (o) Yvhere possible, pack directly from the picking containers without dumping, (4) V.Tien tender varieties are packed in boxes with a bulge, the container should be stored and transported on its side, (5) More educational work should be done with the trade and retail handlers to prevent rough handling from orchard to consumer. That Ladino Clover is proving a soil conserver par excellenoe? A, B, BeaiJimont, Extension Soil Conservationst says, "A newcomer ar.iong forage crops bids fair to become one of our best soil conservers. Ladino, or giant white clover was introduced into Massachusetts in 1923. The rapid increase in the acreage of this legume in this state is remarkable: In 1940 there vvcre a pproximately 2,000 acres of it. Its spreading habit, mat of tough runners and branching root system make it almost ideal for, holding soil against forces of erosion. Being a legume it is rich in protein and excellent for pasture or hay. It thrives best on moist, fertile soils. It appears that this cr<^P may persist indefinitely under favorable grovjth conditions, but experience accumulated to date indicates that aproductive life of 3 to 5 years is a reasonable expectation in Ivlassochusetts." That Indian Orchard, near Springfield, may have derived its name from the wild fruits harvested there by the Indians, County Agent Y.'. T. Locke submits this statement found in the Springfield Library, "Below 'Great Falls' v.'hich v/as Indian Leap, the Chicopee River widens forming v;hat ivas knoivn as Big Cove, embracing nanj'' acres of comparatively still waters which surrounded an island containing four acres of fertile land with grape vines in abundance, also v;ild apples and plum trees. Some of the older residents declare that this island r;as the 'Indian Orchard' from which our village was named. The island is now covered by the flowagc from a canali' Mr. Locke adds that the water impounded by the present dam could cover a good many four acre islands, A_Tip from the Retailer Retail storekeepers meeting v.dth- fruit growers in Springfield said that they would welcome an apple grading law v^hich would require that apples be correctly graded according to quality when on sale in retail stores. They pointed out that if such a law were enforced, and the storekeeper himself were penalized for deterioration in quality, ho would learn to be more careful in handling his apples. He v;ould buy better quality to begin with and he would so regulate his purchases that his fruit would be cleaned up before it had a chanc i to deteriorate. Thus the consumer would get better quality fruit and the conscientious retailer would benefit through the elimination of mis- labeling by his less scrupulous competitors. J, IV. Dayton Public Health Service Finds Sprayed Apples Not Dangerous Most fruit groy;ers are aAvare that for the ptTst three years the U. S. Public Health Service has been conductiz^.g an investigation of the dan- ger to public health from lead and arsenic residues on apples. A 180-page report of their work has been published, ivhich should be reassuring to any wlio fear that their health may bo endangered by eating sprayed apples. Studies were made of 1231 men, women, and children living in the apple grov/ing regions of VJashington. Many of the individuals studied were engaged in orchard spray- • 8- ing and had a greater exposure to lead and arsenic than consumers of apples. Only six men and one women showed anj;- sj'mptoms whatever of lead arsenate poisoning, and these sxTTiptoms v;ere too sliglit to say that these few wire de- finitely poisoned by lead arsenate. The report fails to show that eating sprayed apples that have not been washed is dangerous to health. However, fruit grov/ers should continue to be careful to follow a spray program that will leave the least residue consistent with control of insects and diseases. J, K. Shaw Hormone Sprays It is expected that manufacturers and dealers v/ill exhibit hor- mone "drop control" spray materials at the fruit grov/ers' meetings during Farm and Home ''A'eck. It is probable that most of the brands on the market will be on display. This will afford a good opportunity to growers to ex- amine materials, compare costs, and talk with the vari.ous representatives. L. Southwick Ethylene Dichloride Emulsion • "The"re""h'a've'Teen rUports of very severe injury to several peach or- chards in Michigan from the application of ethylene dichloride emulsion for the control of peach tree borer. One grower is reported to have lost 2,000 out of 3,000 young trees. Although there have been no reports of injury from this material in Massachusetts anyone considering its use should wait until we find out more about the situation in Michigan. J. S.

This is just what vie should expect in view of the se- vere shortage of water in the soil. As mentioned elsewhere in this issue, we experienced a shortage of more than eight inches of rainfall in Amherst from January 1 until June 1. Other sections of the state appear to be equally dry. It may be well to remind ourselves again that a large fruit tree may require as much as 4500 gallons of water during the season. To supply the daily need v:hen air temperatures are high and the loss of moisture from the leaves is excessive, the roots must have access to an unfailing supply. Yl'iere tree roots extend to a depth of eight or ten feet there should be no yellowing of leaves. But if the entire supply of moisture must be ob- tained from a layer of soil two or three feot deep, it is easy to imagine the tremendous competition which goes on between the various leaves on the tree. This competition may result in a dropping of many of the fruits as well as a shedding of some of the leaves, Heavy Peach Crop is Forecast The United Stat'es peach crop will total about 66,000,000 bushels according to the latest forecast as compared vdth 54,000,000 bushels in 1940. Lry weather caused some decline in peach prospects in the southern states during May, Representatives from about a dozen peach producing states net in Columbus, Ohio, June 18, to consider r;ays and means of handling the large crop. Home canning of peacnes is one of the items stressed at that meeting. The group represented all important pcacli producing areas, which incidentally does not include Nnw England. The group requested all branches of the dis- tributing trade and all state and federal agencies including those dealing Y:ith nutrition and home economics, defense and marketing, to support a na- tion-wide cairipaign to stress more home canning of peaches, find also urged the continuance cf sales efforts in the northern states similar to the peach campaign which was developed in the South.

FRUIT NOTES - August, 1941 W. H. Thies Extension Horticulturist Observations in Franklin County Orchards Yhe writ'er' n'as ' just~rriade"ar'ser'ies of 22 orchard visits in Colrain, Aslifield, Slielburne, and other hill tovms in company with Assistant County Agent Stanley Burt. Practically every farm in this area has its Baldwin orchard. T.'hen we think of Franklin County we commonly think of Baldv/in apples because of the prominent part they have played in its agricultural history. Ivlany shiploads of Baldvdns have been exported to England in years past. And even though the export trade has disappeared many thousands of Baldwin trees remain. A large jauriber of these trees are more than 25 years of age, and as stated in the June issue of Fruit I^otes, the Baldwin crop of the current season is disappointingly small. As vife travelled from orchard to orchard during the past tv/o weeks we vrere impressed with tne foliowijig items: (1) A large proportion of the Baldwin trees in Franklin County are of doubtful value from a proi'it making standpoint because of severe v.'inter injury in 1934 or because they are nov; too old or too tall to render economical apple production possible. On prac- tically every farm old, tall, scattered Baldwin trees should be cut down and made into firewood. The wood burning furnace is an ideal market for these old timers. (2) Orchards v;hich are somev.'hat younger, located on good soils and sufficiently compact to permit efficient spraying may well be given more attention. The common practice of cutting hay in the orchard and hauling it to the barn is not increasing the grower's chance of profit from these trees. If the older trees are eliminated considerable land now devoted to an unprofit- able orchard will be released for the growing of hay. '"hatever hay grows in the orchard should be used for mulching purposes except in rare instances vfhere the soil is so fertile that a moderate amount may be removed and fed to livestock. (5) In the orchard, as in other farm enterprises, we are likely to get out no more than ve put in. If we delay fertilizing, pruning, mulching, and spraying until some future time when a big crop is in prospect, the big crop may never appear. \'ie recommend for the more promising Baldwin trees in Franklin County and elsewhere a little investment, as suggested above. If they fail to respond, these trees like the old timers whicli have outlived their usefulness, should be made to contribute to the wood pile. There is reason to believe that the 1942 bloom xvill be fairly heavj^. The coming fall and winter is therefore an ideal time to reorganize the orchard by cutting out the less promising blocks along witn the scattered trees and by doing something to insure a crop of marketable fruit in the rest of the orchard. A Borrov;ed Editorial The following timely statement on "Fruit Grading Standards" in a recent issue of the Rural New Yorker deserves tlie attention of every fruit grovjer in Massachusetts. "Far-sighted fruit growers are looking beyond the minimum grade stand- ards now in force, to something better. Present day regulations call for cer- tain size, color, and blemish standards, mostly directed at oxitvTrd appearance. -2- But now, creeping into the situation is a desire to set up standards which will insure a product to the consumer which v.-ill result in complete satis- faction and repeat orders; standards which will apply to quality from the standpoint of flavor and use. "To be sure, some progress has already been made in singling out the uses and best seasons of certain varieties, as the R. I. Greening apple for cooking, the Delicious apple for eating out of hand, the Y.'ealthy apple for Fall, the Mcintosh apple for late Fall and mid-Winter, and the Northern Spy and Rome apples for Spring. Rut even this is not enough. Orange growers are turning to standards of fruit quality as judged by acid content, sugar content, and other analyzable internal fruit characters. This method auto- matically rules out of the trade those varieties vrhich t-re of inferior qi.iality, and prevents past- season, soft, unappetizing fruit from reaching the consumer. "It is a step in the right direction. It is quality that the con- sumer v, ants and quality he must and will have, all the way from size and ap- pearance clear through to condition, crispness, flavor, texture, and aroma. This is the market of the future, and the ore v.iiich growers mast keep constantly in mind if they are to hold their ovm and progress with the times and with the competition from other fruits and other sections." Chokecherry Leaves Show Autumn Coloring Many Massachusetts roadsides cause the traveller to wonder if the month is October instead of Auj.ust. Here and there we see a blaze of color in chokecherries infected by X Disease. In some cases these plants are dan- gerously near peach orcliards. These telltale signs in chokecherries should be as effective as a red flag in w^arning peach growers about the menace of this mysterious disease. Since 1731 vvhen Peach Yellows were finst recognized, virus diseases of peaches have intrigued the scientist and worried the fruit grower. Follov/- ing in the train of the Yellow^s has been an ever increasing list of virus troubles, including the X Disease which was first noticed in Connecticut in 1933. The visible symptoms of X Disease on peach leaves may le easily recog- nized. According to E. Li. Stoddard of the Connecticut Station, "About eight or nine weeks after grovrth starts in the spring, part of t!ie foliage on an infected tree suddenly will develop indefinite yellovf or light orainge areas which rapidly increase in size and number until the entire leaf is involved. V.'ith the progress of the disease the color intensifies, the yellov: and orange become blended vdth red, and the leaf becomes stiff and brittle. Eventually most of the foliage on the diseased branches will develop the characteristic symptoms and drop with the exception of the tip leaves which rarely are shed. 'H'.'hen the leaf symptoms appear, the fruit on the affected parts of the tree usually shrivels and falls, or continues to hang on the tree as dried up mummies. The disease does not appear necessarily over an entire tree at once but may show at first only on a few twigs, or even on only one twig, spreading irregularly over the tree in subsequent years. This habit often makes it difficult to spot an infected tree in the orchard. The fact that diseased peach trees alv/ays are associated with diseased chokecherries leads to the conolusion that the chokecherry is the original offender. It is not known by what means the disease is transmitted from chokecherry to peach but it is supposed that the transmission is made by some insect vector vhioh has not been discovered vet." The only practicable means of eliminating chokecherries seems to te through the use of a weed killer, i-lor.'ing or even grubbing out the roots is ineffective. Ordinarily a second application on the leaves is sufficient to put the chokecherries out of commission. A new non-inflamraable material of considerable promise is nov>r being tested at the State College. The in- fecting distance appears to be about 300 feet. Russet Injury on Delicious Apples "~ Many" f 'a'ct'ors~c'o ntr i b ut e to the russetting of apples, but fundamen- tally russetting is due to soluble arsenic. Laboratory tests have consistent- ly shovm the merit of lime in reducing or preventin?^ the formation of soluble arsenic, and this informetion is the basis for the lime recommendations in the official spray schedule for apples issued by the State College. The re- sults from our orchard spraying experiments support laboratory results in favor of limt. V,'e have not obtained results to support the h;^othesis that the addition of line weakens the sulfur. While soluble arsenic, in our opin- ion, is the fundamental cause for the russetting of Delicious and Baldwin apples and most of the yellowing and dropping of Greening foliage, its forma- tion in injurious amounts is intimately bound up with cool, moist, slow-drying weather during the early cover sprat's. That ^^,^6 of weather prevailed in 1940 but not in 1S41. Furtheniiore, almost 100% of the growers are novj using lime with sulfur and load arsenate ro tha,t russetting in 1941 in commercial orchards is not as evident as in other years. At IValtham, Delicious trees sprayed v;ithout the addition of lime, show typical spray russet on the apples, wliile other trees sprayed vdth lime, wettable sulfur and lead arsenate in the usual proportions, are free of it. Yvith the type of drying v;eather that has prevailed this year, there is not as much yello'.ving and dropping of Greening foliage as in 1940, and up to the present time the contrasts between lime and no lime in the writer's experi- ments are not significant. The number of pounds of lead arsenate and the brand of lead arsenate can also be factors contributing to arsenical injury on apples. Therefore, on varieties vxhich are especially susceptible, like Delicious and Baldv;in, and vmere scab and curculio are not too serious problems, 3 lbs. of leed ar- senate with 4 lbs, of a high grade wettable sulfur and 6 lbs. of lime w^ould seem to be an ideal combination for the cover sprays. In one large coirimercial orchard \'.'here this combination was used this year Delicious is free of russet, E. F, Guba Kaybe That's IThere They Come From Apple grovrers someti-ies say tliat they see no apple maggot flies be- fore the middle of August. This suggests that the flies may be late in emerg- ing from the ground in an occasional orchard. A migration of flies from other trees is a more logical explanation, as illustrated by this observation made August 12. On a certain farm in xvestern Massachusetts there is a scattering of apple trees around the buildings including Yellov; Transparent and i.lclntosh and a Baldwin orchard about 100 yards away. At the tine of our visit there were about three bushels of maggot infested apples under a Transparent true,! practically all of the apples having dropped to the ground, llo flif^s were in -4- evidence on that tree. A nearby Mcintosh tree showed considerable maggot injury in the fruit and sonie of the apples had already dropped because of maggot infestation. Several flies were observed in this tree. Practically no maggot damage vias apparent on the Baldv/ins. These observations support the testimony of entomologists who find that maggot flies attack early var- ieties such as Transparent, Astrachan, Gravenstein, etc. to a greater extent during July and August. The Porter variety has long been considered a favor- ite of the apple maggot. These apples soften up readily and provide an ideal place for the maggots to develop vrhen the apples drop. This brings up the question, V.Tiere do maggot flies go after the apples have dropped from the tree? If they are still interested in laying eggs it is logical to assume that they will seek other trees the fruit of which is not j'^et infested. Perhaps they move from trees of summer or fall varieties to trees of winter varieties. This may account for the appearance of the flies in Ealdviin trees as late as September. It is quite obvious that if the above mentioned Transparents vrere gathered up promptly and destroyed there would be fevcer flies to infest later varieties. Furthermore, this Transparent tree which will not bear a crop in 1942 will make its influence felt in the rest of the orchard as thousands of flies emerge from the ground beneath it and sally forth in search of a home. Do You Know That the production of plows for tractor use exceeds the production of horse dravm plows in the United States? Disappearance of horses and mules on American farms in 20 years has taken away the capacity to consume the food from 70 million acres, according to the census. This is more than the entire farm acreage of lovia and Missouri combined, and v/ould be sufficient to feed 84 million human population. That the first half bushel of Michigan's Redhaven peaches brought a record price of $30? This was the first commercial offering of the new variety on the Benton Harbor market. It is said to have excellent shipping qualities and if of a brilliant red color. That the annual output of United States fruit canning plants amounts to about 50 million cases? Peaches lead v.'ith over 12 million cases. That the canned fruit and vegetable requirements from the 1941 pack for the armed forces of the United States will amount to about 7,900,000 cases of canned vegetables and 2,250,000 cases of canned fruits? This estimate includes the combined requirements of the Civilian Conservation Corps, Coast Guard and Marine Crops, as well as the Army and Nav^'-. That sulphuric acid mixed with citrus pulp makes a plastic from which Florida citrus field crates possibly may be made in the future? This new dis- covery is part of a recently started i" 50, 000 program of citrus research. That Boj'senberries, Youngberries and Nectarberries account for more than 56 per cent of all bush berry shipments to the Los Angeles and San Francisco markets? Raspberries rank second in popularity with common blackberries third and Loganberries fourth. That a nev; method of determining winter hardiness in apple root stocks has recently been developed by U.S.D.A. workers? The test consists in freezing at 20° F. large numbers of apple seedlings and then selecting from the frozen plants the small number that show little or no injury, ' -5- That 10 years of investigations ot the Fruit Products Laboratory of the University of California have resulted in the perfection of formulas for fruit candies not only pleasing to the taste but high in dietary value? According to ViT. V. Cruess, these candies offer an outlet for surplus prunes, peaches, pears, figs, raisins, and apricots. Fruit candy formulas are prir.ted in Circular 10 of the California College of Agriculture in Berkeley. That Ontario vromen are being organized to do farm labor by the Farm Ser- vice Force in conjunction with the Ontario Department of Labor? They are needed for three kinds of work: (1) on fruit and vegetable farms; (2) in fruit pickers' camps — as camp mothers, cooks and assistants; (3) in canneries and packing houses. That a ladder with a novel joint action so it can be used as either a step ladder or a straight ladder has been invented? This ladder comes in five sizes, is very rigid and should be useful both for pruning and harvesting. That a colloid mill process being tested by the N.Y. Agr. Exp. Sta. in the making of fruit juices ^.Ives additional nutritional qualities to the juice and also strengthens its flavor? The mill may be used on vegetables as well as fruits. Grinding of the cores, skins, fibers and other parts releases concentrated food values not obtained by usual processes. That the oeople of Ireland, in spite of nearness to the European V.'ar retain their sense of Jp-u:":ior? T. L. Doran of the Dept. of Botany, sends us this clipping fro:u the Meath Chronicle and V est Heath Herald published in Cavan, Ireland. Quoting from a column called A Fly Round Cavan, "A funeral was seen passing through Bailioboro at half past tv.'elx-^e on Sunday night: four men dressed in white were carrying the coffin: there was no lid on the coffin, and the corpse was sitting up and he was singing to the top of his voice: 'Eat More Fruit.'" That an orchard sprayer of an entirely new tj'pe is being tested in a Maryland orchard? A. ?. Vierheller, Extension Horticulturist, writes, "The machine consists of a large steel cylinder, hauled horizontally as a trailer back of a tractor. The cylinder houses the spray tank, motor, large air propeller, f.nd a system of nozzles. The liquid is fed to the nozzles at 40 pounds of pressure and is blown into the trees with great force by the propeller which makes a driving mist. An operator located in the cylinder controls the amount of spray and the speed of the propeller." That the presence of very small quantities of a given element in leaves may be detected by means of a spectroscope? In recent experiments with grape leaves the boron content of leaf samples from treated and untreated vines of several varieties was determined by this raothod. These analyses are in very close agreement v;ith the observed deficiency symptoms. The Ontario variety which seems to be very susceptible to the deficiency, shovred a much higher boron level in both treated and untreated vines than the other varieties. That apple ice cream is a recent addition to the list of delectable apple products? 0. C. Roberts submits this recipe which he recommends: 3 qts. 20$^ cream, 24 whole eggs, 5f- lbs granulated sugar, 1 teaspoon salt, 5 lbs. whole apples. Hix all ingredients except apples and cook in a double boiler or steamer until they just barely reach a boil, then cool. Slice the unpeeled and uncored apples and cook in as little v;ater as possible until they are soft enough to run through a sieve. After this allow to cool and add pulp and Juices to the cream mixture. Pour into freezer. This nix v/ill make approximately 5 gallons of apple ice cream. That an excessive application of borax may affect the storage quality of apples? Australian workers report that such an application affects ad- versely the storage quality of apples of the Jonathan variety by increasing the aznount of internal breakdovm. Applications of one-half pound per tree resulted in no injury, but applications of one pound, and especially three pounds per tree were harmful. Not only was the keeping quality of the fruit affected, but the leaves of trees receiving excessive amounts of borax were small and paperj' v.dth sjnnptoms of scorching. That fruit pectin is proving very effective in surgery in the treatment of wounds? After more than three years' use of pectin solution in the treat- ment of a sizable series of various types of wounds, investigators find that such therapy results in a very prom.pt response \".dth cleaner wounds and a rapid groTA.'th of tissue. The method seems to be of particular value in the chronic type of lesion v;hich often resists all other therapeutic efforts. That the State of Missouri is planning to tax apple growers to enforce the present grading law and to ad->-ertise and promote apples? The J'issouri Senate passed the rlissouri apple tax and grading bill on June 18 which provides for a penny assessment on every bushel of apples except for 500 bushels vfhich are exempt. The bill now must be signed by the Governor. That a more general use of standard U. S. grades for apples is indicated in the Ilortheastt The State College in cooperation with the Division of Mar- kets, is now working on a simplified outline covering the more important U. S. grades. An illustrated chart similar to the one on Massachusetts grades pre- pared about 10 years ago, is contenplated. That August is a critical month in the new strawberry planting? A vigor- ous grovjth of runner plants should be stimulated this laonth, v.'eeds should be eliminated regularly, and for best results runner plants should be properly spaced. That tlie Depart.aent of Labor and Industries has a labor lav bulletin which contains the complete law relating to the vrorx of the Division of In- dustrial Safety and that it covers labor laws as related to Agriculture? Following are three items in these laws: (1) The Division of I^idustrial Safety has no jurisdiction over agricultural labor as such, except in such accessories as stripping, sorting, manufacturing or packing tobacco, cider making and other similar operations. (2) The child labor laws are liberal in the case of children employed in domestic service or on farms. Children between 14 and 16 who have completed the sixth grade may be granted a permit to work on the farm or to engage in domestic service. (3) During vacation or outside of school hours, no such permit is required nor is a permit re- quired for children above the f.ge of 15. In case of certain other t^.'pes of work (not farm work) however, permits are required up to the age of 21. That Apple Llarket Reports are issued regularly by the Division of l.iarkets of the Liass. Dept. of Agr. from August to !,iay, twice weekly during the heaver shipping period, and v.'eekty for the remainder of the marketing seasonj These -7- reports may be obtained for a moderate charge by sending a request to W. R. Cole, Sec'y. of .I.F.G.A., Arnhf^rst, "lass. The Effect of Hon.ione or Grovrbh Substance Sprays on the Keeping Quality of Apples ~-~- Recent experiments at the University of Illinois indicate that tre use 0-'' hormone or grovrth substance sprays does not Impair the keeping quality of apples sprayed with such materials. In these experiments Jonatnan, Grines, and r.'inesap apples xvhich had been sprayed with three different brands of hor- mone raaterials were subjected to a critical exa;mnation at monthly intervals during the storage period. Y-'ith apples picked at the optimum stage of maturity no significant difference in keeping quality was observed betwesn those sprayed vith the various gro'v.'th substances and those which had received no spray. Jonathan apples v;hich were allovjcd to remain on the tree two weeks beyond the optimum stage of maturity ripened faster in storage, lost weight m.ore rapidly, and developed a higher percentage of Jonathan spot than the early picked apples. Late picked Grimes ripened faster and lost weight more rapidly than thore picked at the optimum stage of maturity. Late picked Yfinesap, free from v:atercore, seemed to keep as well and lost vreight no more rapidly than those picked tvro weeks earlier, but thr percentage of vxatercore in the late picked fruit was considerably higher thrn in that picked earlier. The results of these e::<:peri,Tients suggest that ripening of apples in storage is not affected by the application of hormone sprays vjhen the apples are picked at approximately the optim.um stage of maturity. However, excessive delay in harvesting varieties v/hich respond to the use of horm.one sprays is likely to shorten the storage life of the fruit. 0. C. Roberts Does It Pay to Store Ordinary Apples? An appie buyer of a form.er day classified apples according to three grades: good, ordinary, very ordinary. \"e all know xvhat should be done with "very ordinary apples." liow- about the middle class, ordinary apples? The following summary of receipts and expenses furnished by a Y/orcetiter County grower, tells its ovm story. Concerning a certain lot of applet, he says, "At picking time I realized that they were not all good enough grade to stand a storage e::pense of 26fi a bushel, so I put them in a less expensive storage and paid 15i2^. Other expenses were: picking 10/, supervision and hauling 3/, box 10/, nails, slats, shredded paper, liners, etc. 3/, transportation to storage (20 miles) 5/, transportation from the storage to the point of sale 5/, and some^vhere along the line, grading, packing and sorting 10/. Then if these apples sold for 6r:/ the cormission amountr;d to 0-^-/. Adding all of these items, vre get a total cost of G7g/ which means a net loss of 2|/ a bushel in addition to the cost of grov;i}ig the apples. "These are figures which are nlain as day and accessible to all of us, and I wonder if a more thorough knowledge of them might not stop the movement of some such apples to market. I feel that if we can possibly work a lot of the cheap apples into horticultural by-products, cider or stock feed, we will be helping ourselves soi'icwhat and the apple business tremendously."

FRUIT NOTES - September, 1941 T.-. H. Thies Extension Horticulturist Here's an Idea Although apples have been graded according to either the U. S. or the Mass. Grade standards by some of our larger growers for a number of years, the bulk of our commercial crop is sold with relatively little grading. Many ordinary crops are sold "Orchard Run" vdth "Ciders" out. One of the most common practies is to sort out so-called "No. I's" and "No. 2's." Your guess as to the meaning of the term "No. 1" is as good as the writer's, per- haps better. Generally, "Na. 1" means the best apples in the orchard. But the border line between "I's" and "2's" is flexible. At least, it is flexible enough to fit both the grower's conscience and the pri»e offered by the buyer. We've actually seen a farmer sorting out so-called "I's" and "2's" from a crop which looked as if it had not been sprayed. There are probably as many different conceptions of a "No. 1" apple as there are grov;ers using that term. "Someone has suggested a "{Futility" Grade as appropriate here.) But when we say "U. S. No. 1," we have in mind a standard in which color, tolerated blem- ishes, etc., are clearly defined. A "U. S. No, 1" apple has the same meaning in Massachusetts as it has in Michigan. It is a common denominator for apples from, any section, recognized wherever apples are bought and sol^d. Further- more, Federal purchases are being made on the basis of U. S. Grades. The idea we want to convey is briefly this: Instead of continuing to pack apples on the hit and miss basis here outlined, why not pack accord- ing to the U. S. standards? These grades are less complicated than most folks believe. And v/hen once we get in mind the few simple requirements, it is like measuring the individual crop with a yardstick instead of a rubber band. In this issue of Fruit Notes will be found a brief statement of the U. S. Grade Requirements. It will be noted that the first three Grades, "Fancy," "No. 1," and "Commercial,'' have the same blemish tolerances. They differ only in the amount of color. The "Utility" Grade involves another set of blemish tolerances. Here we have a plan by which apples of 1st quality may be separated from those of 2nd Quality. Sorting the crop on that basis instead of the out- dated No. 1 and No. 2 basis, we are prepared to sell in competition vath other apples in any market in the country. If fruit is of High Color and has been sorted out on the basis of 1st Quality, it may be marked "U. S. Fancy." If it has Good Color, it may be marked "U. S. No. 1." In the case «tf Mcintosh, the first grade requires 50% Color, the second grade, 25% Color. Hormone Spraying We will be interested in reports from fruit., growers anywhere concern- ing the success of spraying to control fruit drop. Special blanks are avail- able and have been sent out to a few grov/ers, but they are not by any means necessary for reporting. A copy of Bulletin No. 381, "Spraying to Control Preharvfcst Drop of Apples," is available to anyone who writes in for it. L.

The Nev/ York State Fruit Testing Association This association is well knovm to many of our fruit growers- It has introduced many new varieties bred by the W. Y. Geneva Experiment Station and elsewhere. The annual meeting is scheduled for September 18 when there will be discussions of new varieties led by many v;ell knovm pomologists. The r eport for the past year shows a decrease in business. The association must have in- creased support from fruit growers if it is to prosper as in the past. It has done a good work and is worthy of support from all progressive fruit men. J. K. Shaw Fruit Growing in Canada On a recent vacation trip, the writer travelled through the fruit growing regions of the Annapolis Valley and New Brunsvdck. The Annapolis Valley is an old fruit grov/ing section. In recent years grov/ers have had their share of troubles and many of the orchards look neglected. Evidently fertilizer pur- chases, spraying and pruning have been reduced to a minimum. Other orchards look vigorous and healthy. The crop does not appear to be very heaver and the quality not the highest. In the past, most of the Nova Scotia apples have been exported and of course the eJtport market is now non-existent. However, I was told that the British Government had ordered a million barrels to be dehydrated for shipment to Great Britain. This will be quite a sizeable proportion of the crop, vAich is usually around 2,000,000 barrels. It will tax the dehydrating facilities of the Valley to handle this quantity of apples, but they think they will be able to do it. The New Brunswick orchards seen were around Frederickton. These or- chards are younger and on the whole look better and the crop is considerably heavier than that of Nova Scotia, although presumably the total amount will be less. J. K. Shaw -4- Do You Know That sawdust is being used successfully as a mulch in nut nurseries? A mixed oak and pine sawdust applied three inches deep over the surface has given highly satisfactory results in conserving soil moisture and in retarding weed grov.'th at Beltsville, Maryland. The sawdust aided materially in capturing light rains. That a reduction in freight rates has been granted to apple growers in the Northwest amounting to 2 to 11 cents per box? This will mean an estimated saving amounting to approximately $1,600,000 for the growers in that area. That "Banged-up Fruit Means Knock-dorm Prices?" This slogan on a placard is being displayed prominently in some of the packing houses in Maryland. That the 1942 Marginal Tree Removal Program provides for a payment of 75 cents per tree for trees over 20 inches in diameter? The rates of payment offered by the AAA for the "removal of diseased or uneconomic fruit and nut trees, the major portion of whose fruit is of inferior quality" are as folloi.vs: Trees 5 to 12 inches in diameter, 30 cents per tree; trees 12 to 20 inches in diameter, 50 cents per tree; trees over 20 inches in diameter, 75 cents per tree. That the commercial apple crop this year is estim.ated to total 125.6 million bushels compared vdth 114,4 million last year? Indications are that the greatest increases in production over last year are in the summer and fall var- ieties. That the California Valencia orange production is estimated this year at 27.1 million boxes? Last year 26.9 million boxes were produced. The esti- mated lemon crop will be 16,2 million boxes compared vifith 12 million last year. That more than 5,000 ounces of apple pollen was gathered by commercial companies for use in hand pollinating orchards In Chelan County (Washington) alone during the past season? That smoked, sugar-cured ham, boiled in cider, is considered a delicacy? It is reported to have been one of George V.'ashington' s favorite dishes. That tender grass, dried, is estimated to contain about 23 time^ as much Vitamin A as carrots, 22 times as much B-2 as lettuce, 9 times as much B-1 as green, leafy vegetables and 14 times as much Vitamin C as tomatoes and citrus fruits? That a nev;, promising, non-inflammable weed killer (ammonium sulfamate) is now available in small quantities at a moderate price? That the Damson is one of the few self-fertile plum varieties? A few days ago the writer sav; a Damson tree in Bristol County bearing an exceptionally heavy crop even though there v.'ere no other varieties of plums nearby, v/hich seems to support the above statement. That there are approximately 624,000 species of insects in the world? Of about 20,000 recorded in this country, 6,000 at least, are actual pests. That there are about as many rats as people in the United States? The Federal Fish and Wild Life Service says there are about 123,000,000 rats in this country, almost one for each human inhabitant. The annual "rat loss" is estimated at $189,000,000. • 5- Mice sometimes damage fruit trees as early as September? Control measures are most needed in orchards which have a heavj/- grass cover. Too much reliance must not be placed in wire guards. That much may be learned from roadside cuts, gravel banks, building excavations, etc., about the fitness of a soil for agricultural purposes? There are literally hundreds of places in Massachusetts where soil profiles have been exposed to show the characteristics of our various soil typos. That an annual pruning plus tvra or three applications of Bordeaux Mix- ture is likely to mean the difference betvreen a crop of good grapes and a few poorly filled clusters of partially \vithered berries? Vj"hile harvesting the grape crop ^ve have a good chance to evaluate our pruning and spraying methods. That an obscure fungus disease of apple trees may cause the leaves on one or more branches to take on a silvery appearance? This disease is appropriately known as Silver Leaf. It was observed in several Massachusetts orchards during the past summer. A Visit to the Champlain Valley A recent letter from H. P. Gilraore of Vrestboro tells of a visit to the Cham.plain Valley of New York. Among his comments are these: "The orchards I visited had a fine crop of Mcintosh of fully as good size and better color than ours here. They have had groiving conditions very similar to ours this past season. It has been very dry so there is very little scab in the well cared for orchards. Codling moth is a little more in evidence than in our best orchards. Second brood leaf hoppers were just showing up and I saw a few infestations of red mite and maggot. So their conditions are very much like ours. The main var- iety is Mcintosh. That variety makes up 80 or 90% of the crop in the orchards visited. In the older orchards Fameuse was used as a pollenizer but since the loss of the Canadian market, the trees are being grafted over to Delicious and Cortland. It may be a bit too far north for Delicious which do not look as v;ell as some of ours. The Baldwins were badly frozen out in the winter of 1933-34. Some Greenings are also grown. The severe freeze also seriously injured some Mcintosh trees as evidenced by some black heart and dying back. V.inter injury is one of their worst fears ^vith the result that nitrogen fertilizers are used rather too sparingly to prevent late grovrth. The one outstanding difference on first inspection is the absence of hurricane damaged trees. They were fortunate to escape the hurricane of 1938. Labor costs are slightly lower than ours. I had a very enjoyable visit with A. E. Burrell who gave me a lot of information on orcharding in the Valley and made my trip most interesting." Effect of Slope on a Raspberry Planting Does the direction of slope have anj'-thing to do with success in raspberry grovdng? According to Andrev: Love of Auburn it exerts a real influence. He writes: "In 1935 I planted l/3 of an acre of raspberries on a northern slope. On the top of the slope are woods which check southern and southwestern winds. At that time I had two other beds on the other side of the hill on equally well drained and v/ell fertilized soil, one an acre, the other -^ acre in area. This gave me beds on direct northern and direct southern exposures for comparison. The acre bed on a southern slope grew v/ell and suffered severe winter injury for several years. The hurricane did a good job of v/recking it so I plowed it under in 1939. I have never had any real luck with the \ acre bed, also on a southern slope. Some years I get a fev; berries but most years, I take the job of growing -6- a beautiful hedge as one of my losses. On the northern slope I have had crops every year, and good ones too, until this year.' I find that very few rasp- berries around the county lived over last winter." Pointers from the Maryland Summer Meeting IrTa recent News Letter issued by A. F. Vierheller, Extension Horti- culturist in Maryland, vre note these points of interest: (1) In a terraced peach orchard at Smithsburg, Md., bait pails are being used as one means of controlling Oriental fruit moth. A mixture of lignin pitch and terpinyl ace- tate is placed in quart engine oil cans, using 8 to the acre. (2) New cover crop plants under test shov; Reed Canary Grass and Tall Oat Grass as promising for' grov.'ing mulch material outside the orchard. (3) Concerning the use of ethy- lene dichloride for peach borer control, the vnriter says, "It is necessary to tamp all soil cracks around the trunk, then pour the proper amount of material, diluted according to directions for tree age, on the soil around the base of the tree and not on the tree trunk. (4) C. P. Harley says that water core in apples is due to high temperature causing hydrolysis of starch, thus increasing osmotic pressure in the cells, causing them to rupture. If the leaves are well supplied v/ith nitrogen they build up starch much faster and if high temperatures occur, water core results. In short, the apple cells become "droimed out." More About Ethylene Dichloride Emulsion Ethylene dichloride emulsion looked very promising as a control for peach tree borers when it was first introduced. It still looks promising. But the number of reports of iQjury following its use indicate that it is still in the experimental stage. Most cases of injury have been traced to careless prep- aration or application of the emulsion. In other ;vords, it hasn't yet been made "foolproof." On the other hand, injury has sometimes resulted where everything seems to have been done according to directions. These few cases suggest that some factors such as varietal differences, condition of the trees, or soil type may be involved. Further reports on the use of this material have come from M^^chigan, New Jersey and New York. The Michigan Experiment Station has tried ethylene dichloride emulsion in various parts of that state during the past three years without observing injury anywhere. But several Michigan growers had very se- vere injury to a large number of trees as a result of the application of this material in the fall of 1940. One grov.'er severely damaged 3,000 out of 4,000 3-year old trees. The injury appeared in the form of dead areas on the roots four to six inches below the ground level. This is not like the usual form of winter injury in Michigan, v;hich appears at or very near the soil level. M. A. Blake, in recent issues of the New Jersey State Horticultural Society News, reports on injury vdiich occurred on the Experiment Station grounds at New Brunswick. Some 3-year old seedling peach trees were treated v/ith ethy- lene dichloride emulsion in October. A short time later some of these trees showed evidence of severe injury. Professor Blake described the injury as fol- lows: Severe injury from this chemical in the form of brovmed cambium and inner bark of the main trunk near the soil appeared on a few trees a few days after the treatment. The affected area extended upward towards the branches. By mid-winter the brown bark of severely injured trees could be detected at some distance. VyTiile injury was relatively light, the inner bark and cambium were only slightly discolored. In the more mild cases the discoloration was yellowish and the tissue of the inner bark appeared more spongy than normal. -7- Such slightly injured trees T;ere delayed in foliation the following spring. Such trees greatly reser.ble winter injured specimens, including the symptoms of bark injury. A report from New York State states that where injury from ethylene di- chloridc occurred, it was due to improper or careless preparation and application of the emulsion. Ethylene dichloride emulsion v/as used again last fall on several of the State College peach orchards. It was applied on several different dates and on trees of several different ages, but in only one orchard was any injury observed. It is very doubtful if injury in this case was due to the gbhylene dichloride. It looked more like winter injury to trees weakened by unfavorable soil conditions and an unusually heavy infestation of borers. Although there is no clear-cut evidence of injury from ethylene dichloride in Massachusetts, experience else- v/he're indicates that this material should be used with caution. For the present it seems wise for Massachusetts growers to stick to v/orming with a knife and vdre for a few trees, or paradichlorobenzine for large numbers of trees. If some growers wish to try ethylene dichloride emulsion experimentally on a small scale, they should be particularly carefal about three things: First, make up the emulsion to the proper strength. And don't add a little more for good measure. This may please the buyers of your peaches but it won't work here. Second, measure out carefully the amount of emulsion to be applied to each tree. Don't overdose. The old saying, "If a little is good, more is better," doesn't apply. Overdosing vjHI certainly get you into trouble. Third, keep the emulsion off the trunks of the trees. Dr. Snapp's first recommendation was to pour or spray the material on the trunks. Later experience shov;ed this is a dangerous v;ay of applying the material. He therefore changed his recommendation a year ago and advised keeping the material off the trunks. Anyone using this material should keep careful notes on hov; the emulsion was made up, the amount used, time of application, and condition of the trees. Then the trees should be observed every week or two during the remainder of the fall and early winter to see if and v;hen injury appears. J- S. Bailey Ta'ild Grapes fFe delightful aromas of the fruit harvest season are among the uncounted dividends of the fruit business. It matters not whether apples, peaches or grapes are in the process of being packed, each lends its characteristic aroma to the packing house. For lack of suitable adjectives, the writer refrains from attempt- ing to describe the subtle fragrance v.'hich cones from each ripening fruit. V.'ild grapes seem to possess an odor not even surpassed by their cultivated relatives. A few days ago this fact was impressed upon us as \ve carried a peck of wild grapes in the back seat of the car during a tv/o days' trip. Eacli time the door v;as open- ed these vdld grapes, in spite of their tough skins, revealed their presence. Later they were made into grape juice and in that form proved a second delight. Not that we would recommend the cultivation of wild grapes. But if they grow in profusion nearby let's take time to pick enough of them to enjoy their character- istic odor and some delicious juice or jelly as well. Incidentally, it is claimed that few, if any, of the blossoms which develop on wild grapes are perfect. In other words, they are either staminate or pistillate. This accounts for the fact that some vines produce no grapes at all v;hile others produce an abundant crop.

FRUIT NOTES - October, 1941 V/. K. Thies Extension Horticulturist Items from Here and There Nev; Baldwin. A Baldv.'in apple of exceptionally dark color has been sent to the State College by a small orchard ownier in Auburndale. The apple is apparently a "sport" or bud variation, rather uncommon in the Baldwin var- iety. Variation in Starkin^. Another striking variation was observed in the orchard of John Lang in East Taunton. One branch of a 10-year-old Stark- ing tree bore about a dozen apples which shov/ed a few narrov/ reddish stripes on a green background. The rest of the apples on the tree were normal Stark- ings. Late Maggot Fly. An apple maggot fly v/orking overtime is the re- port of a Hampden County "grower. One fly vms observed while this grov/er was picking apples, October 6, Original Delicious Tree. A report from Iowa says that the original Delicious apple tree" was kiricd~y the sudden freeze that did so much damage to apple trees in that section last Armistice Day. Adventure in Marketing. The entire crop of apples in British Colum- bia v:ill be marketed~ver one de"sk this season. Definite prices have been established according to grade and if sold for less, in order to move them, the government vfill make up the difference to the growers. Horticultural Research in China. There is still an interest in fun- damental research even in war-torn China. The projects under investigation reported from the University of Nanking in Chengtu include methods of pruning Grimes Golden apple trees, pollination and fruit setting of citrus fruit trees, simple methods of storing citrus fruits, dehydration of fruits, etc. Trucking Peaches. One motor-trucker in the Northwest tells the story of hauling Vj'ashington peaches into the Middle West at a profit; and picking up eastern peaches for his back haul part way "iVest — at a profit. Northv/est Apple Crop. Better Fruit magazine says "Providence and adequate government'^inanccd production produced the finest crop of apples that the Northwest has witnessed in a decade." Florida Cloudburst. Recent rains have apparently settled the dust in Florida"!! The University of Florida rain guage shov/ed more than 12 inches during a three day period while Cross City, nearby, reported 14 inches in 48 hours 1 o^acksonville received a mere 5 inches during one 24-hour period. Horticulture and Defense. "iVriting in the Rural New Yorker, H. B. Tukey says']! "The protecti've value of fruits and vegetables in the diet is being recognized as never before. Horticulture is definitely a part of the defense effort." Baldwin and Spy Crop in 1942. The 1941 crop of Baldwins and Spies in New York State is reported as being smaller than 1940 Vi'hile that of R. I. Greening, Mcintosh, V.'eaith^^ Delicious, Cortland and Ben Davis is in each case larger. This is very similar to the situation in Mass. and suggests the likelihood of a heavier crop of Baldwins and Spies in 1942. Maybe that neglected Baldwin or Spy orchard deserves a little extra attention during the next few months. Notes from New Hampshire. A recent letter from C. 0. Rawlings of Nev; Hampshire brings these interesting comments. "Most of our growers vrere surprised at the size of Mcintosh considering how dry the season has been. We had practically no internal cork where Borax had been applied, but in or- chards where none ' vra.s used, considerable shov;ed up. In certain blocks cod- ling moth did considerable damage. We will be obliged to tighten up on our control methods for this pest in those blocks next year." Fertilizing Peaches. A timely word on fertilizing of peach trees is offered to Connecticut grov/ers by H. A. Rollins. Referring to trees v/eakened by winter injury or dry v.-eather he says, "Trees of this t2'pe should respond to a little extra care next spring such as a second application of fertilizer. Growers are urged not to attempt any practice this fall that will encourage late growth and so make them subject to winter injury, "[here hen manure is being used as a fertilizer, wait until the ground is v/ell frozen before apply- ing it or, better still, wait until late winter or early spring." Bouquets and Bees. The yield of apples in a 20-acre Pennsylvania orchard has been increased 16,100 bushels over a period of three years as a result of using bouquets and bees, according to J. U. Ruef, Fruit Specialist at the State College. Previously, the annual yield of Delicious in this or- chard had not exceeded 1800 bushels. During the 3-year period the yields were 8500, 13,000, and 6000 bushels respectively. The estimated increase makes allowance for a 1000-bushel per year natural increase, which would re- sult from the larger size of the trees. Priced at 75;^ por bushel for orchard run fruit, the increased yield meant a gain of $12,075 from the 20 acres over the 3-year period. Rodent Control Supplies. A detailed report concerning Rodent Con- trol Supplies has been received from the District Agent, U. S. Fish and Wildlife Service, 1140 Park Square Building, Boston. Quoting from this report, "In order to conserve finances, simplify procedure, increase efficiency and co- operate more completely with the county agent, the Rodent Control Fund will operate in the future on a cash basis, v/ith the exception of canned red squill rat bait when bought in lar^;e amounts, in which case 30 days credit vrill be allowed. Future rodent control supply orders v.d.11 be sent only to county agents direct, or to the cooperator on instructions from the county agent." Any grov/er interested in getting the Field Mouse Rodenticide or other rodent control material should consult his county agent. Mammoth Maple Loaf. Imagine a single leaf of a sugar maple tree measuring 15 inches in wi'dtlT and 20 inches from tip to point of attachment on the branch. This leaf is on display in the office of R. H. Holdsworth of the Forestry Department. It was found on an exceedingly vigorous sprout grow- ing on Mount Toby. -3- Praise for Ben. In an old file we find a clipping from the March 30, 1895 issue of a New York nev/spaper which lauds the lov;ly Ben Davis apple to the skies. "Having no trace of flavor of its ov/n, it readily takes any other flavor and becomes a novelty to the housev/ife and the canner. Chicago and the South and Vest are dead stuck on this apple and buy it at any price. It will keep sound from one picking season to the next. And the Ben Davis never rots. Bruise it if you want to, but that bruise v/ill simply dry up. It is big and red and solid, and pretty as a picture. But there's no more taste to it than a door knob, and no more smell than a piece of ice. And yet they raise more Ben Davis than any other kind and they've got as high as *9 a barrel for ■'"em." Outbreak of Bitter Rot. A severe case of Bitter Rot (not Bitter Pit) has appeared in a commercial orchard in the town of Dartmouth. The crop of Rhode Island Greenings on certain trees is practically v/orthless. This disease is fairly common in Pennsylvania, but fortunately is not very prevalent here. This particular outbreak might have been prevented by more thorough spraying. A sufficiant number of sprays v.'as applied, but only about one third as much spray material as was needed to cover the trees thoroughly, due in part to an antiquated, low pressure sprayer. How to Save Gas. A writer in the Rural New Yorker gives 15 simple ways of saving gasoTTne^ Here are some samples: How to accelerate. Don't jam your foot down on the accelerator. It doesn't get you away any faster and it pumps more gas than you need into your engine. A heavy foot uses excess gas. Hov; to stop. Coast to a stop if you can. Every time you put your brakes on while the motor is running fast, you throw away power and gas. 1941 Rainfall as Related to Fruit Size and Color While the season of 1941 v/ill not be remembered for its large apple crop nor for the profits of 20 years ago, certain unusual characteristics in the behavior of orchard trees are quite outstanding. The season started out with remarkably low rainfall and bids fair to end in the same v:ay but during mid-summer rainfall was about normal. The record of rainfall at Amherst is as follows: March April May Normal 3.70 3.35 3.60 1941 1.63 .55 2.87 Our trees have made a remarkably good vegetative growth, and even though the apple crop is not large, the individual apples are of normal size and well colored. The large average size of apples at first thought seems queer, but perhaps the following explanation v;ill throw some light on the sit- uation. The deficiency of rainfall up to the month of May may not be signifi- cant because there vias enough reserve m.oisture from the winter season. Further- more, the early drying out of the soil and the accompanying warm weather were favorable for early root and leaf development. Then the adequate rainfall in June and July kept the trees going and enabled them to make efficient use of the early developed roots and leaves. Abundant sunshine in August and September favored starch formation in the leaves which seems to be a prerequisite to good color development. The rainfall for 1341 seems to have been very favorable for both tree and fruit. J- K. Shaw ALIT.INI SEMINAR - Massachusetts State College, November 14 and 15, 1941. This program is intended pr_imarily for alumni although other interested individuals are welcome to attend. A copy of the complete program may be obtained by v,'riting Roy E. Moser, Stockbridge Kail, M.S.C., Amherst, Mass. Two sessions of special interest to men engaged in horticultural vrark have been arranged. June July Aug. Sept.

Although these products enjoy a good sale at roadside stands and by a few commercial specialty manufacturers, there is comparatively little knov.Ti about the beach plum and its jelly making properties. The Department of Horticultural Manufactures at the Massachusetts State College v;ill conduct an investigation of the beach plum for the purpose of standardizing procedures for making jams, jellies, and other preserved prod- ucts from this fruit. Such factors as the effects of variety, maturity, freez- ing, and canning on the pectin, acid, and sugar contents vdll be studied. The nutritive properties of the beach plum and its products v.dll be considered also. Because of the growing demand and favorable publicity the beach plum is receiving, an increase each year in the size of the crop is not unlikely. The time is ripe for extensive studies of the beach plum so that it may soon take its place with other better knovm fruits. A. S. Levins Apple Grower Enthusiastic about Irrigation L. B. IJichols"of Hanover Is sure that irrigation pays. He has sup- plied additional water to his 25-year-old apple orchard for the past 4 years, after 6 years without it. The yield has increased about 50^ under the same fertilizer program, and most of his fruit is in the 2 3/4-inch or better class, instead of 2 l/2. He harvested more than 1000 bushels of Mcintosh from a 2-acre block this season. The color was exceptionally good. The irrigation layout is about as simple as one can imagine. Using 2 l/2-inch fire hose, bought 8.t 17/ per foot including couplings, the water is raised to the highest point and allov;ed to flow over the surface v/hich is cov- ered by a heavy grass sod. The hose is shifted occasicnalljr to provide dis- tribution. The maximum lift in the orchard is about 35 feet. A 4 H.P. engine operates the 200-gallon pur minute centrifugal pump. Mr. Nichols has no record of the total amount of v'ater used, but it is safe to say that each of the 65 trees received at least 1500, and perhaps 2000 gallons during the season. Planting a New Orchard H. P. Gilmore of V.'estboro sends in this report of his experience in setting out apple trees last spring: "On April 15 while the ground was still wet we set out a 2-acre block of Mcintosh with Early Mcintosh for fillers. Be- cause of the rush of early season work and lack of help we did not get a second 3-acre piece ready for setting before May 1, so heeled-in these trees in my garden. About that time I read R. A. Van Meter's article in Fruit Notes stat- ing that the first year in an apple tree's life was very important and that the first month was the most important of all. I decided to set out the 3-acre piece at once rather than wait a year, so the trees were set on the day of the twilight meeting at my place, about May 10. We set the trees in one day in rows 40 ft. apart, 20 ft. in the row, making about 54 trees per acre. That afternoon we took the 500 gal. sprayer and puddled in each tree, sticking the nozzle v;ell into the ground, using about 400 lbs. pressure until the ground boiled. The nozzle was the same as was used in resetting hurricane damaged trees. V'e unscrevred the 8-nozzlo cross head from the regular broom handle and screvred on a single nozzle with one l/4" hole. A small handful of nitrate of ■5- potash was put around each tree before puddling and soil was shoveled in to level it off. Ten days later I noted that every tree had started to leaf out. I vrent up to see the first block set and it was just starting. The second block although set several v/eeks later came into leaf first and has done better all summer. All the trees arrived from the nursery at the same time. The second block has made v;onderful groirth for such a dry season and is well ahead of the block which was not v/atered. Mouse Populations Increase According to the U. S. Fish and Y.'ildlife Service, there has been a gradual upswing in populations of tree girdling meadov; mice throughout the north- east during the past two years. This increase has been checked by drought con- ditions in some sections, where limited amounts of food and cover have pre- vented populations from being higher. Infestations are spotted, and numbers often show extreme variation in different parts of the seone orchard. Since these rodents seek the most favorable habitat, lar^e numbers have concentrated in areas of heaviest grass cover. The scarcity of natural food this year in- creases the danger of possible damage to fruit trees during winter months. Population counts in fruit areas shov/ed as many as eighty mice per acre on September 1st. Thus, before mnter sets in, such orchards will be in the serious infestation class. In some cases, disced orchards often had from sixty to ninety-five per cent of all tree bases infested. Cultivation practices during late summer have had little value in reducing mouse populations. On the other hand, such operations often served to reduce the amount of food and cover, thus forcing the mice to concentrate in tree rows and increasing the chances of winter girdling. Vfhilc fev; instances of early damage have so far been noted, fruit grovrers in Canada experienced girdling as early as last August. ITith the com- ing of cold weather, damage will soon start in many orchards. Fruit growers are urged to begin control operations as soon as possible, varying bait place- ments according to the number of active signs found present. The rodenticide may be obtained through any county agricultural agent. Mouse Control in Storage ' (Robert M. Htlrg of the Fish and IVildlife Service, with headquarters at the Federal Building in Worcester, has prepared this timely message for fruit growers. ) In this region there are three kinJs of mice v/hich damage apples in storage, namely, the meadow mouse, the deer mouse, and the house mouse. There- fore, a consideration of the methods by which we can control them is important. At the outset the storage place must be made mouse-proof. No one can afford to risk storing such a valuable crop as apples unless the storage structure has been made both rat-proof and mouse-proof. Even v.'ith a mouse-proof building, mice do get in, either by entering the doors \vhen one goes into or leaves the storage room or by finding refuge in packing boxes and hence arc carried into the storage. The best time to start thinking about controlling these mice is before the apples are stored. In other words, place the poison in the storage before it is filled \rith boxes. It might also be wortliv;hile to place some be- tween the boxes while packing if this is possible. .6- There are several things that can be used to put the poison in, such as pieces of pipe, mailing tubes, short pieces of tile, boards nailed up against the wall where mice run, or a home-made type poison station. Usually, tablespoon amounts of poisoned baits distributed throughout the storage in poison stations is sufficient for effective feeding and control. Small amounts v;ell distributed seem to ivork better than large amounts in fe^ver places. This vdll supply a permanent poison available to the mice at all times. Powdered strychnine. Arsenic, and Thallium are effective poisons. (ZnP is not a good poison to use because it releases odors and does not last long, i.e., it oxi- dizes readily.) There are several choices of poisons to be used because there are several animals to deal with. Follov/ing is a report of the effectiveness of these poisons on the three mice with which we have to contend in storages. Strychnine is effective only in the control of deer mice; moreover, resistance to it can be built up. Arsenic gives good results in the control of all three mice but is an emetic at certain level's! Thallium, moreover, is excellent for all three mice because it has no v;arning powers or taste. Suggestions for permanent type bait materials for use in mouse control in storage are as follows: Attractants Used. Since all these mice are grain eaters and since grain is both a good attractant and an easily worked ingredi- ent, steam crushed oats, oatmeal, dried bread crumbs, or a mixed grain of oats and v/heat nre desirable. Of course, other small grains can also be used. Ad- hesives Used. To any one of these attractants an adhesive must be added. And only enough of the adhesive is used to permit the poison (powder) to stick to the grain or attractant. Either a shrup or an oil is desirable as an adliesive. Of the various oils, light oil is preferred, such as mineral oil or olive oil. If a material such as cottonseed oil or peanut oil is used it should be cooked first. In any event don't use bacon grease, lard oil, etc., because you are dealing with the meadov; mouse and these arc not acceptable to him. Of the sy- rups, corn syrup is satisfactory. Ratio of Poison to Attractant. Strychnine is mixed in the proportions of 1 oz. of pcv;dered stryclonine to 12 quarts of cereal (Strychnine sulphate should not be used because it is more bitter, less toxic, and more costly); arsenic is mixed in the proportion of 1 oz. of micro- nized arsenic to 10 quarts of cereal; viith regard to Thallium no data can be given except through personal contact (Thallium may be purchased on the open market) . Poisoning can be supplemented by using small vrooden-base snap traps baited vdth material acceptable to all three mice. These traps should be set at various places throughout the storage. Traps, however, must be looked at once a day or oftener depending upon the number of mice. Moreover, traps should be reset and rebaited frequently, as fresh bait is preferable. In summarizing mouse control in storage, the prerequisite in any storage place is to so construct the building that it is rat or mouse-proof. Even v.'ith a mouse-proof structure nice do got in, therefore, poisoning before packing is necessary. Permanent tj^pe baits should be prepared and put in tablespoon quan- tities in bait stations frequently placed throughout the storage. Moreover, this poisoned bait may be supplemented by the use of snap traps.

FRUIT NOTES - November, 1941 W. H. Tliies Extension Horticulturist Fall Care of the Small Fruits Planting "' Late fall is considered to be an ideal tlnie to set out red rasp- berry plants. Plants so set are ready to start growing earlier in the spring than spring set plants. The only possible objection to fall plant- ing would be in case of a winter with unusually light snowfall which night cause sone of the plants to heave. This can be avoided if a forkful of mulch is throTA.m over each plant. It is about tir,ie to mulch that stravirberry bed for the winter. Don't wait until the ground has frozen or considerable winter injury may be done to the crovms. According to reports from Illinois, one of the principal causes of "he plants" which produce no fruit, is Y;intcr killing of the fruit buds in the croivn. A. P. French Profits From Cultivated Fluoberries A nev; crop. Fab ul ou's prices. Get rich qu.ick. Or is it? Y.Qiat do blueberry growers think? In riev/ Jersey they feel that they must get 20 cents per quart to break even. At times the price received by the grower has been close to this figure. In Michigan they feel that they must get 30 cents per quart to "make a little." And they are worrying about the price getting too lov/. They have even r:iade arrangements with canners to take part of the crop if the price does get too low. In liassachusetts three prominent cranberry and blueberry growers stated recently that they have made more money per acre on blueberries than on cranberries. Considering the valvie of the cranberry crop, this is a startling statement, J. S. Bailey Quince Rvist on Apples liost "of~the "cedar rust" damage to apple fruits this year T,vas caused by quince rust. In some seasons, losses from apple rust are greater than those from quince rust. This year, not only was^there a scarcity of cedar-apples or galls of the apple rust disease on the cedar trees, but spores v/ere unusually late in reaching maturity because of the dry weather prior to the apple blossom period. By the time apple rust spores were ma- ture, the young apples and many of the leaves had passed beyond the stis- ceptible stage • Quince rust behaved differently. Being perennial in the branches of red cedars .and junipers, it was abundant as usual. Horeovor, its spore development in those branch cankers appeared not to be delayed so greatly as in the case of apple rust spores on the cedar galls. As a result, there was an abundance of mature quince rust spores in some parts of the state during the applo blossom period, the most susceptible stage of the fruits to either rust disease. The susceptible period extends from a veiy few -2- days» to rarely 10 days, after petal fall. Infections of quince rust this year apparently occurred during the general blosson-period rain of Hay 8-10, the 18-hour wet period on I'&Y 17 (in some sections of state only) and possibly during the ov-ernight vret period of liay 23, although the last rain must have been near or after the susceptible period. Hence, the bulk of the damage to fruits this year no doubt started during the rains of IJay 8-10 and (or) May 17. Since the intervs.l between the pink and calyx sprays was so much longer than between the caly>: and first cover, and especially since the v;et period during bloom was so much longer than on the 17th, it is quits probable that most of the fruit infections from quince rust occurred during bloom. The interval betvi-eon sulfur sprays must be evun shorter for the control of rust tlian for the control of scab. Limited observations indi- cate less damage this year from quince rust where a spray or dust preceded the rainy period of liiy 8-10 than where no blossom period application v/as made, 0. C Boyd S .LI .A. Program, to Continue As this is being v/ritten, the following announcement comes from the office of the Surplus i.'arketing Administration in Bostom "The Surplus Marketing Administration annovinces that the Apple Purchase Programs in I.5aine, Hew Hampshire, Vermont, Massachusetts, PJiode Island and Connecticut mil not be terminated November 15, 1941. Purchasing will continue until fi-^rther notice. Prices, terms, specifications and conditions included in Pu.rchase Announcement iTo . 3 dated Octobsr 13, 1941 will remain unchanged." Time to Overhaul the Sprayer 'He offer the suggestion that December is a better month than Ifey for overhauling the sprayer. Le.bor is likely to be more scarce than ever next spring, and sprayer parts difficult or impossible to get. "-Thy not take the old sprayer apart betvreen now and the holidays and make sure that everj''- thing is in tip-top condition. H- A- Rollins expresses the same idea in his last issue of "Seasonal Fruit yotes." He v/rites, "If you are going to need new equipment or repair parts for farm machinery for this next year, place your orders as soon as possible. Delay in ordering may mean very slow delivory or no delivery at all. Don't 7;ait until late v/inter or early spring to overhaul the spi^yer. 'b of the valu.e of all crops grown? The total value of all crops amounts to about 10 billion dollars arjiually. The annual value of fruit crops is about 421 million, truck crops 256 million, potatoes 250 million, ornamental crops 209 million, and ntits 20 million. That strav/berries contain at least 90^, i7ater? Recent analyses by E. B. Holland and "7, S. Richie shov/ strawberries to have the highest water content of any tree or small fruits grown in this region. The average -irnter content of 10 varieties of raspberries was '36%. Blueberries were found to contain 80.5^^ and cranberries 87.2;;i. The water content of three varieties of apples after coring and paring v/as as follows: Mcintosh, 85.4fi; Baldwin, 85.7Joi Vfeaithy, 87.4^. That "heavy" or fine textured soils actually weigh less per unit of volume than so-called "light" soils v/hich are of coarser texture? These terms, according to A. B. Beaumont, arose from the fact that the finer soils are harder to work and require more pov:er in the process of cultivation. That a rubber tired ■vra.gon or trailer may be constructed at rela- tively little expense? If interested in this piece of home made equipment, drop a line to the v«riter and fvill details vrill be supplied. That the removal of soil from around the trunk of a fruit tree in the fall tends to encourage v/inter injury? The lower part of the trunlc and -4- the roots are likely to be injured when the first cold weather sets in if deprived of the protective layer of soil. It is an excellent idea to remove grass and weeds fron around apple trees as a means of keeping mice av;ay from the tree. But if vegetation is removed in the fall the space should be filled in with sand or gravel. That peach leaves seem to contain^ on the average, more potassium than apple loaves? J. R. llagness of the Bureau of Plant Industry in a re- cent talk at the Horticultural Seminar in /jnherst, stated that 1 1/2^ is about the border line of deficiency of potassium in peach trees, Virhereas apple trees may contain only 1%, Thus peach leaves with a potassium con- tent of 1 l/^% would obviously be deficient, whereas apple leaves v;ith that same amount might still contain enough for normal needs. That peaches have been groivn from peach pits in two years? That is the record achieved by scientists at the University of California. The process was speeded up by removing the kernels, soaking them in a nutrient solution of agar, sugar, and vitamin B\ for three weeks. This treatment results in rapid germination. By the time the young trees are S months old they are ready for field planting and by their second birthday the young trees have produced peaches . That gum may exude from a peach tree for any one of half a dozen reasons? Th? most common cause is the peach tree borer. Other causes in- clude riieclianical injury'-, winter injurj'-, bro^/m rot, and anything else which tends to injure the inner bark. One tree \'^as observed this fall in which a sr.-iall amoimt of gum had exuded from all of the tips attacked by Oriental fruit moth. That one acre of corn requires about 4,300,000 povmds of irater? This is equivalent to about 19 acre-inches . Although the exact water re- quirements of an orchard are not laiown, a mature orchard may require as much water per acre as corn. It is estimated that a mature apple tree may require 4500 gallons of water during the grov/ing season. Tliat the roots of a plant grow later in the fall and earlier in the spring than the above groimd portion of the plant? Careful studies of the behavior of roots show that some root growth 2-iay take place in apple trees even during the v/inter months. This emphasizes the need for setting fruit plants early in the spring. If set during April while the air is still cool, the roots have a chance to develop before the buds. If set during /'ay the plant is under a handicap because top growth begins before the plant has a satisfactory root system. That a growing squash has Vi'lthstood a measured pressure of 2 l/2 tons? Professor T.'. S. Clark performed this experiment many years a go in Amlierst, using a unique metal "harness" with a lever arrangement for adding weights as the squash grew. Ho also attempted to measure the root system of the squash vine. He calculated a total root length amounting to 15 m.ilcs. That the P.egional Iiarket wholesale auction of fruits and produce opened its 7th season October 27 at the Boston Regional Produce f.iarket in Cambridge? C. F. Dutton, tho auctioneer, conducts sales each Monday and Thursday. -5- That elm leav-js roay be used for mulching a strav,-berry planting? 0. C. Boyd calls to our attention the fact that elm leaves do not mat dovm as much as other leaves, such as maple. Elm leaves tend to curl up, thus nrovidinc a fluff^' ti^e of mulch material which does not smother the plants. That the moldy condition often found in the core of an apple is caused by spores v/hich enter through the caly^: end? Delicious and horthern Spy are quite subject to this sort of thing. 0. C Boyd informs us that one of the common molds causing moldy core is a species of Alternaria. Mold spores which enter through the open calyx and pass through the calpc tube to the core find ideal conditions for germination and grov«rth inside the apple . That the effective control of apple scab in lassachusetts dates back a little more than 20 years? In an old file wc find this statement under date of August 23, 1921: "Fruit grov/ers ' meetings v;ere held in Groton and Littleton where elaborate experiments arc being conducted by Professor !\ ;-\ l. ^ ■i^.-*- . Applf^s for Dairy Cov:s ' ThlV c'T\\~seeins to have -^aten : lore than her share of ap^^les and :.iay be in a "barrel of trouble ," If >ier ev.Ticr had fed that quantity ever a period of about 12 days, -the results v/culi have boen quite different # "Unfcrtunately, " writes J. G. Archibald in the Rural Few Ycrker» "most carA's are not possessed with sound judgment. They are liko sor.o people in the natter of over indul- gence in something they like. Probably over indulgence in apples when oppor- tunitjr presented itself has "lad disastrous resr.lts vfith more t han one brssy and it is such oasos that fi:: thc:.:solvos in the minds of the OTv^ner and his noighbcrs ." "Vjhat then may bo the safe limit in rationing apples tf cpws? i'c hard and fast rule can be follcvcd blindly. Size end individuality rf cows require that we -isc oi'.r judg,: ...nt in this as in all other matters pertaining to successful feeding. A gooc'. old friend of mine who vfas a successful dairy- man and orchardist fed cull a-;^les to niikJng ccvrs regularly but ho always said. Tot more than a peck to f, cov; cV-.ily.' I bcli.ve that is t->. g >od general -7- guide although I have Icnovm people who fed tvrlce that many. Apples may take the place of a portion of any other standard succulent feed such as silage, root's or grass but it should be remembered that they have a somewhat higher water content than either silage or grass and adjustment should be made ac- cordingly. "On a dry matter basis, a peck of apples is equivalent to about 10 povmds of good corn silage. It should also be remembered that apples arc a strictly carbohydrate feed. Their content of total protein is low and it is not highly digestible. Roughly, they contain about l/6 as much digestible protein as good corn silage does. For these reasons apples cannot take the place of any considerable part of the grain in a milking cow's ration. I strongly suspect that much of the drying up of cor.'s reported v;hen apples are fed is due to the failure to recognize these iiiiportant facts. "Curiously enough, the recorded results of feeding apples to cows are very meager. In two experiments at the Central Experimental Farm, Ottawa, Canada back in 1904 and 1905, apples vrere substituted for a portion of the ensilage and roots custoi:iarily fed. The cov;s relished the apples and seemed to thrive on them, snail gains in weight being noted. There ■v\'as a slight in- crease in milk yields when the apples were fed. "In 1905, at the V.'ash. Agr. Exp. Sta., whole apples were ensiled alone and also with alfalfa hay, in the proportion of 80f! apples and 20^% hay. The straight apple silage did not prove particularly sat is fact or^-, being too soft for best results, but the apple-alfalfa silage was a good product, verjr palatable to cows, and maintained milk production on a verjr high level." 0:16 I'eans of Changing the Bearing Year IiTthe' October" Issue of the American Fruit Grower, we find a report of a sprayijag experiment at the University Experimental Farm, Kearneysville, W. Va. A block of 13-year-old York Imperial trees, 25 to 30 feet high and almost completely bierjiial, was used for the testing of two materials: (1) A tar oil distillate and (2) a material laaown as DITO, a prepared mixture of dinltro-ortho-cyclo-hej:j'-l-phenol in oil. The trees were sprayed at the early pink stage, check trees and treated trees being selected at random through the orchard. These materials proved very satisfactory from the standpoint of practically complete removal of the crop which was the objective of the spraying, 'ifhere a single application of 2T' tar oil distillate v;as used prac- tically no apples set on those trees. Since 1953 the even numbered years have been relatively short apple crop years in the U.S. v;ith much better prices prevailing than during the odd numbered years. I'any orchards, however, have been producing their main crop during the odd numbered years with disastrous financial results to the grower. This experiment suggests a method by v/hich the on year for part of such bien- nial orchards can be changed and orchard production as a whole made more \ini- form from year to year without the complete loss of the crop. It would appear to merit the serious consideration of grov/crs who have certain varieties in a strongly biennial condition. FRUIT NOTES Volume Kumber 12 December, 1941 In this Issue!

FRUIT NOTES - December, 1941 V;. H. Thies Extension Horticulturist The Fertilizer Situation The situation on fertilizer supplies for 1942 indicates a definite shortage of certain nitrogen materials, possibly some curtailment or delay- in supply of other items, and some increase in price of all ingredients ex- cept for lime. Priority demands for large amounts of nitro£:en for munitions use, and the interruption of normal shipping facilities by boat to routes by rail are factors which add uncertainty as to supply and which, along with rising costs of bags and labor, add to the price, NITROGEN materials are likely to be limited in supply of certain items, at least until the fall of 1942 when several new nitrogen plants are ex- pected to be in operation. Cyanamid promises not over l/5 the normal supply costing at least ;i:10 more per ton. Agricultural Urea is mostly diverted to munitions use, with probably none available for farmer use. Nitrate .of Soda remains available for farmer use, but at curtailed amounts, costing ITlcely upwards of $5 or more a ton, Sulpliate of Ammonia gives promise of being available in largest amount, "showing the" least increase in cost and is suggested as the principal nitrogen material for farmer use. Natural organic nitrogen carriers are high in price, with soy bean meal possibly the least expensive of this form of plant food, PHOSPHATE supplies are being seriously affected by transportation problems. Superphosphate (16-20^) material appears most drastically affected by transportation problems to a point where many local distributors at present are unable to quote a price or be assured of further requirements. Triple Superphosphate will probably be available in about the same amounts as last season, at an increased cost over $2 per ton. ¥ihile this material v;ill probably be the cheapest source of phosphoric acid the supply is limited we understand and some distributors may not have it. Ammophos will not be available for supply, Steai.ied Bone meal supplies are short, quoted about vl6 or higher per ton, and the supply of Precipitated Bone is short. POTASH supplies of high grade are more favorable for the Northeast and may be adequate for the spring trade at perhaps only a slight increase in cost. Supplies of the higher grades for the country in general, however, may be short, occasioned by a 4-montli strike and may necessitate substi- tution of lower grade manurt, salts. MIXED FERTILIZER goods are bting quoted at least by some distributors at reasonable increases ranging up to about ■i.S a ton. The increased cost of some tobacco grades may be double this. Vife assume that local distributors may have reasonable stocks on hand for early spring requirements. Nevertheless, we urge planning now for antici- pated farm requirements and early placement of fertilizer orders to insure priority in supply. R. W. Donaldson -2- Leaf Analysis as a Means of Determining Fertilizer Needs of Fn.iit Trees Determining the availatle nutrients in tlie soil as a means of learning fertilizer requirements for crops has received some attention in recent years. There is not a perfect correlation betvjeen nutrients in the soil and in fruit trees though there is usually some correlation. Determin- ation of nutrients in the leaves may suggest the fertilizer needs of the tree, Workers in the U.S.DjA. find that a potassi'om content of over 1% in apple leaves and 1,5^ in peach leaves indicates an ample potassium supply. As it falls below these points there is increasing likelihood that a potassium fer- tilizer will be beneficial. Last July and August there appeared symptoms of a nutrient deficiency in one of our young apple orchards at the State College. Leaf burn v;as evi- dent and the older leaves fell prematurely. The symptoms resembled those on other trees growing on a soil knoT/^Ti to be low in magnesium. Determination of magnesium in leaves from (1) partially defoliated trees, from (2) a tree in the same orchard but carrying its leaves, and from (3) a tree in another orchard that was making very good grov;th, followed the pattern of tree grovd;h. The very good tree was highest in magnesium content, the partially defoliated trees lowest, and the other tree intermediate. It iiiay be significant that these de- ficient trees v;ere fertilized v.-ith potash (and nitrogen) last spring. Potash fertilization has been shov.T^ to bring out symptoms of magnesium deficiency. Y,e expect to find out next season if these trees are actually suffering from a lack of magnesium. Y«'e have found that long continued liberal nitrogen fertilization may develop symptoms of potash shortage. These and other facts show the signifi- co.nce of a proper balance between the many chemical elements necessary for sat- isfactory groi»,i:n and production of orchard trees. This does not mean that everybody should change his orchard fertilizer from nitrogen only, to a com- plete fertilizer, perhaps including calcium, magnesiiim, boron, copper zinc, manganese and other elements that have been shown to be necessary for fruit tree growth. If nitrogen alone results in satisfactory growth and production, continue to use nitrogen only, but if performance of the trees declines and especially if deficiency smptoms appear, it is time to study the situation and find the remedy. J. K» Shaw Origin of Some New Apple Varieties Probably not more than 5^ of the national apple crop coines from varieties of knovm parentage. Most of the commercial varieties are chance seedlings. Only v/ithin recent years has the product of the plant breeder found its way into our commercial markets. The Cortland is one example of a commercial variety v:hose parentage is known. Most grov.-ers are familiar v.-ith this variety and know that it represents an attempt to combine the high qualities of the Liclntosh with the keeping and shipping quality of the Ben Davis. . The follov/ing list of other nctv varieties is presented to clear up a misunderstanding as to their parentage. The Macoun variety is a cross betv»een Mcintosh and Jersey Black. The origin of such varieties is expressed by placing the letter "x" between the parent varieties: Macoun (:.;cIntosh x Jersey Black). Kendall (Kclntosli x Zusoff) Early Ilclntosh and Milton (Mcintosh x Yellow Transparent) Sv/eet Mcintosh (Mcintosh x Lawver) Lawfam (Fameuse x Lawver) Lodi (Yellov: Transparent x liontgomery) Sweet Delicious, Medina, and Nev/fane (Delicious x Deacon Jones) -3- Apple Grower Pleased with Sawdust j.iulch Paul V.'ashburn of Leominster has been using spare time to good advan- tage in transferring a huge pile of sawdust to a relatively droughty part of his orchard. Using a truck body holding about S-g- cords he has spread 160 loads around the trees in a c-acre area. At 4 tons per load, that means a total of 640 tons of wet sawdust. Making full allowance for the large amount of water which it contains, that's a lot of sav/dust. Paul is delighted with the results. Young trees which were not doing very well before are now making good grov.'th. A liberal layer of sawdust on a hillside must aid very materially in the penetration of rainfall. It must also prevent surface evaporation to some extent, and if sufficiently heavjs it helps to hold dovm competing vegetation. Unlike mulch materials containing more nitrogen, which decay rapidly, sawdust is -/aluable mainly because it stabilizes the moisture supply in the soil. ViTiere sav;dust may be had for thf hauling, this method of mulching may well be considered as a means of utilizing labor and trucks at odd times. Seagraves Honored H. S. Seagraves, pioneer fruit grover of V.'est Newbury, was the re- cipient of a set of Bailey's "Cyclopedia of Horticulture " at the final twilight meeting of the season in Essex County. Meeting at the Brooksby Farm in Peabody late in August this presentation from friends and neighbors came as a complete surprise. After spending a number of years in the clothin^ business in Boston, Mr. Seagraves took over the management of the Long Hill Orchards which he has successfully managed for more than 20 years. During these years he has exerted a real influence on the fruit industry in Essex County and has shov/n a spirit of friendly cooperation. His friends and neighbors have also seen fit to con- fer upon him the title, "Dean of Essex County Fruit Growers." V.'e join in con- gratulating ?Iarry as he receives this unique honor. Sm.all Fruiis Investigations at Beltsville, lid. At the recent horticultural "seminer in Amlierst, J. R. Magness told of research now under v;ay in the breeding of cranberr^/ varieties resistant to "False Blossom." Some of these ncv; varieties appear to b e more productive than the varieties now being grown. Ho also stated that a new type of cranberry, the cells of which possess double the normal number of chromosomes, has been developed by the use of that magic chemical of plant breeders, colchicine. Investigators arc also attempting to develop blueberries V;-hich will thrive on upland soils, lie. stated that the Blakemore strawberry is now the most exten- sively planted of all strawberry varieties. An Interesting Old Timer On the farm of V.'. J. Nutting in Leominster there stands one of the largest Baldwin trees v;e have ever seen. The trunk circumference at a point about a foot above the ground is 11 feet. Tiie circumference of the outer branches is 129 feet. Iv.r. Nutting, v;ho has lived on this farm for about 75 years, says it v;as a large tree v.'hen he was a boy. He recalls harvesting 15 barrels of apples from this tree in a single season 50 years ago. It is in- teresting to note that graft unions are still apparent on the branches. Evi- dently this was a seedling tree grafted to Baldwin 100 or more years ago. I -4- Results with lioniione Sprays V. e are interested in hearing, from more growers regarding their 1941 "hormone" spray program and results. The more reports we have, the better can V'le evaluate this nev; method of drop control. Please send your report (as brief as you li':e) to me at Massachusetts State College. L. Southwick Boysenberr5' Too Tender for Massachusetts Frequent inquiries arc made concerning the possibilities of the Eoyscnberry in Massachusetts. Except for limited trial or for a novelty, this dewberry is not adapted to our climatic environment, largely due to a lack of v.dnter hardiness. Even in New Jersey, according to the State Horti- culrural Society Nevs, it requires adequate v;inter protection to make it a satisfactory hoiae garden fruit, and is considered too tender for commercial planting. L. Southwick A i-Iote on Meadov; ilice It is a cause for speculation as to just why field mice do not attack the cultivated blueberry. Evidently, there is no case of girdling on record. It so happens, however, ti;at apple bark is one of the more favored foods of mice and it is hoped that suitable control measures have been undertalfen in orchards, especially young orchards, where mouse runs have been in evidence this fall. The proper use of the rodenticide distributed through the Fish & V.'ildlife Service has proven 100>j effoctive in our orchards at the College. L. Southwick Preventing Rabbit Damage Rabbits seem to be quite numerous this fall in certain localities. If such a locality happens tc be near a youiig apple orchard, considerable bark injury may be the result. In a small experimental planting at Li. S. C, rabbits have already caused some damage. If no control measures were taken, it is very likely that injuries v/ould become increasingly extensive follov.ring snowfall and colder weather. 'Vith the limiting of their food supplies, rab- bits often turn to chewing bark and cutting off tv.'igs from the lower branches of apple trees. Some protection can be had v:ith small trees by usin^, high wire guards. But the most effective control consists of eliminating the rab- bits. The American Fruit Grower states that Michigan State College has de- veloped a repellent v.-hich will keep rabbits from gnawing the bark. Seven pounds of pulverized rosin is mixed with a gallon of alcohol and &llov«ed to stand 24 hours in a warm room. One gallon of repellent is supposedly enough for 150 to 200 2-year old trees. L. Southv;ick Do You Know That the first strawberries of the season in Florida brought a fab- ulous price? A recent news item from Plant City, Florida, says, "The first strawberries have come into the market here, and brought 45 ^l pint. Cool weather has revived the plants and the rains vrhile heav^'-, have caused no ma- terial damage to the berry fields. Movement of berries, provided weather con- ditions remain favorable, should get under v;ay early next month in a light way by refrigerated express." That a detailed survey of production practices v/as made last summer in 19 strav^berry plantings in Bristol County? This survey, conducted by H. F. Trevett, revealed an average yield of 6661 quarts per acre. Among other thing^^s, the survey shows quite conclusively that fertilizer practice alone, bears little or no relation to jaeld. Success in straivberry growing is associated v.lth a nu.'nber of related factors. That several large, luscious strawberries v/ere picked in a Spring- field garden on the first day of December? A. ii. Robinson of 76 Miller Street is the man who produced this unusual crop, proof of which appears in the December 2 issue of the Springfield Union. That live cells in the skin of an apple are capable of developing the red color pigment, v.'hereas dead cells are not? The failure of storage apples to t ake on additional red color, even v;hen exposed to ligrit, is be- lieved to be due to the death of cells in the skin. In a 1932 report from the Boyce Thompson Institute, Arthur reports that most of the epidenr^al cells were found to b e dead in apples stored until November 8, That v/ooden apples are proving useful in teaching apple packing at one of the migrant labor camps in the Northwest? On hearing this report, someone remarked that Ben Davis apples are evidently no longer available. That the fuel value of v/ood is almost directly proportional to its density? For example, dry hickory wood, which v;eighs 4500pounds per cord is about equivalent in fuel value to soft coal. Sugar maple, weighing 4,000 pounds per cord, has a fuel value 7/8 that of coal. 1'i'hite pine weighs 2200 pounds per cord and its fuel value is 2/5 that of coal. Sound apple wood should have a fuel value approximating that of sugar maple, vhite oak, red oak, and beech, namely, 7/8 that of coal. That one's mouth may be more efficiently cleansed by chewing an ap- ple than by using a toothbrush? This is especially true of a tj-ps of apple -.vi'iich requires considerable chewing. Further infonnation on this subject will appear in an early issue of Fruit Notes. That an average dairy cow, during the grazing season, will remove from the soil 115 pounds of nitrogen, 26 pounds of phosphoric acid, 93 pounds of potash and 37 pounds of calcium oxide? Even v.lth conservation of the manure, one-half of the nitrogen and phosphorus and 30)b of the potash may be lost to the pasture soil. That a new material known as ammoni'om sulfamate is proving effect in killing poison ivj/" and other unwanted plants? On poison ivy, dosages be tween l/2 and one pound per gallon of water applied at the rate of one to 1;|- gallons per hundred square feet of lemd has given excellent control. Tests of this new material are being planned for Massachusetts next season. That the production of fruits for distribution in fresh, dried or canned forms is expected to increase 1.5'/; (from 14.8 million tons this year to 15 million tons in 1942). It is expected that the consamption of the 12 major fresh fruits may amount to 135 pounds per person in 1942 compared with 136.5 pounds per person in 1941. This slight decrease is due to the fact that larger requirements for dried and canned fruits will reduce sli-,htly the quan- ive / titles of the 12 major fruits available for consumption in fresh form in 1942. That the U. s. has supplied more than 80^1 of the fresh fruits and vegetables imported into Canada during the past 15 years? Canada has been the most important market for American exports of fresh citrus fruits, grapes, and certain berries. The major portion of this movement has consisted of com- modities not produced in Cojiada or those which can be shipped at a time when similar Canadian products are not available. That foxes and coyotes, considered as carnivorous animals, are also fond of fruit? In a recent bulletin on "Food Habits of the Coyote," issued by the Fish and 'fildlife Service, the author points out that this animal is in- clined to eat v.'hatever food is readily available. Records show that coyotes v,rill eat grapes, figs, prunes, pears, apples, and various wild fruits. The prize fru.it-eating coyote of this study, trapped in California, had his stomach filled with fruit, - 30 grapes, 8 prunes, and pieces of pear. In the 17 states studied, hov;ever, cultivated fruits made up only \/'6 of l^o of this animal's food. Wild fruit made up 1 l/'6%. They Say It 1/Vorka You've heard the expression "There are tricks in every trade." Fruit growing is no exception. Here are three examples of Yankee ingenuity in New England. J. V,'. Collins of Yi'estminster, Vermont writes, "Noting that you recom- mend a ring application of Borax, I am taking the liberty to say that for the past three years vre uavt- used the Cyclone seed sower for the application of this material, and find it possible to make a very even and satisfactory (to us) application. You know, no doubt, that tiiis is a device for applying small seed, which is distributed by turning a crank. Thirty pounds per acre has been the amount o^ Borax used in all cases," T. M. Rorrie of V.'estwood wanted to propagate some nev.- grape vines from mature vines of good varieties in his vineyard. Instead of making cuttings and v/aiting for them to ta.kc root he follo'.ved a suggestion made at a tvdlight meeting, laying do^m a few "arras" and burying them with soil. By late suriimer he was delighted to find that they had developed a strong root system. These plants may be separated from the parent vines next spring and planted in a new location, tlms saving at least a ]'e-s^r in establishing a new vineyard. At the Clark Farm in Shelburne crov/s were doing considerable damage in a extensive strav/berry planting. Hearing that croxvs were afraid of snakes tne ov.7ier made several "i.ritatiou snakes" using rubber hose, rope wrapped with cloth, etc. These v;cre laic in conspicuous places in the strawberry planting. After that, according to the owner, no crow c£me near the place. The Story of Sulfur Believing that fruit grower? are interested in knowing more about the common materials used in grov.-ing fruit, v;e intend to include in the next few issues of Fruit Notes some interesting facts about sources, method of prep.Ta- tion, other uses, etc. In the Janu&.:ry issue we shall include a story about Sul- fur obtained from a series of pamphlets belonging to 0.

FRUIT NOTES - January, 1942 W. H. Thies Extension Plorticulturist Here 's An Idea Y/'ith a heavy demand for nitrogen in the making of munitions, several of the nitrogenous fertilizers are entirely off the market while others will be both scarce and expensive. This will probably mean that many of our sod orchards will either go mthout the annual spring tonic, or some other means of stimulating the trees will have to be devised. If a good yield is to be obtained in 1942 and in 1943, tree vigor must be maintained. In a sod orchard, additional nitrogen is almost certain to be needed eventually, and if 10 pounds of nitrate of soda per tree gave good results last year, we naturally would like to continue with the same fertilizer program. But suppose vm cannot obtain the same nitrogenous fertilizer used last year. It is obvious that a complete fertilizer car- rying, let us say, one-quarter as much nitrqgen as the nitrogenous ferti- lizer, would have to be applied at the rate of 40 pounds per tree to pro- vide the same amount of nitrogen. Such an application v;ould, of course, be a fine thing for the cover crop but might be hard on the pocketbook. A broadcast application of a complete fertilizer would occasionally be very desirable, particularly where a "nitrogen only" program has been followed for a number of years, although a complete fertilizer applied at the usual rate per acre camiot be depended upon to supply as much ni- trogen as the trees may need. But there are at least five things which Massachusetts growers may v/ell consider as possible substitutes for the commonly applied nitro- gen carriers. (1) Use more mulch. Almost' anj'thing in the way of organic matter found within hauling distance, regardless of the time of year, will pro-ve beneficiAl in our sod orchards. Hay, straw, corn stalks, potato vines, saxvdust, or seaweed may be used to compensate for the anticipeted shortage. (2) Use poultry manure where tree and grass groirth show that it is needed. Precautions concerning amount and time of application should be observed. (3) If the sod is reasonably heavy, harrow the orchard once or tv;ice in early spring. In many orchards, there is an accumulation of organic matter iRhich dates back 10 or 15 years or more. This may be the year to cash in on a little of this material. A light harrowing during May will give the grass a setback and bring about the decay of some of the or- ganic matter and thereby provide some nitroi_,en for the trees. Harrowing should be done in such way that erosion ir avoided. (4) If the trees are at all brushy, somewhat heavier pruning nay be in order. This may be the year to do the pruning v;e intended to do last year. By pruning out vreak, shaded, downward grovdng parts of branches, and by a fairly liberal thinning of poorly located wood throughout the top, we can bring about a more effi- cient distribution of the available nitrogen, and thereby invigorate the rest of the tree, (5) Cut out extra trees. In nanj'- orchards there is -2- need for cutting out every other diagonal row in order to give the trees adequate sunlight and to eliminate crovj-ding belov; ground. Thus, we not only add to the supply of vrood for the fireplace but we give the remain- ing trees a better supply of nitrogen, sunlight, water and other things which accompany balanced nutrition. More mulch, more efficient pruning, better spacing, and in some cases a little early spring harrowing, will go a long way toward stimulating our sod orchards and therebj'- maintain good production. Poultry manure may also be used to good advantage. Some Facts About Sulfur The yellow magician, sulfur, has held the center of the stage of world progress for nearly 4,000 recorded years. Ancients dispelled evil spirits v.-ith it. Chinese produced gunpowder with it. Egyptians bleached fabrics v;ith it. Artists made paint with it. Early sculptors bronzed statues Vsiith it. Alchemists tried to make gold with it. Drug- gists make medicine of it. Prepared foods contain it. Agriculture and industry are dependent on it. Plants, animals and humans cannot live without it. Sulfur is truly a magic element. At least 2,000 years B.C., pagan priests were using sulfur in their ceremonial rites. Homer, in his Odyssey, mentioned its use for fumigation, and Pliny, another famous Greek of that day, spoke of four different kinds of sulfur for medicinal and tex- tile uses. Until comparatively recent times, Sicily was the chief source of the world's upply of sulfur. In the 15tn Century a large deposit of this material mixed with limestone and other impurities was found there. For the past 35 years practically all of the sulfur consumed in this coun- try has come from mines located in the Gulf Coast regions of Louisiana and Texas where large deposits are found at depths ranging from 500 to 1500 feet below the surface. During 1940, the sulfur industry succeeded in meeting the greatest demand for this material in the history of the United States. About 2^ million tons of sulfur were shipped during that year. The estimated re- quirement during 1942 is 3 million tons. Stocks of sulfur are noxv near an all time high. Instead of six months' supply available at the beginning of the other World Vi'ar, it is estimated that there is now enough sulfur above ground to last nearly two years. Crystalline sulfur melts at 240° F. Thus, by pumping super-heated water into the deposit far under ground the melted sulfur, almost chemically pure, is pumped out and allowed to solidify. Aside from the enormous demand for sulfur as a fungicide, this interesting element finds its way into the following industries: fertilizer, pulp and paper, rubber, rayon, oil, iron and steel, paint and varnish, etc. About 50 pounds of sulfur are required in the production of one ton of paper used in printing. One pound of sulfur is used in manufacturing each pound of rayon which finds its way into clothing and even rubber tires. One pound of sulfur is used in the 17 pounds of rubber which go into the av- erage automobile tire. Eighteen pounds of sulfur, as sulfuric acid, are used per ton of steel. The first scientific use of sulfur as a fungicide goes back to 1853 xvhen DeBary published his great work on cereal rusts and smuts. Soon afterward, sulfur came into general use in France and adjoining countries as a dust in the control of pov/dery mildew of grapes. In recent years, France alone has used about 100,000 tons of sulfur annually in protecting its vineyards against grape diseases. The importance of sulfur in the growing of apples is too familiar to require emphasis. Our pest control is actually built around the use of sulfur. V«e are indeed fortunate tliat sulfur in its various forms, including the various brands of v^ettable sul- fur, are still available in spite of the heayj^ demand for sulfur in indus- try. Incidentally, one of the wettable sulfurs, flotation sulfur, comes as a byproduct in the making of coke. The hydrogen sulfide v;hich must be removed fr^m illuminating gas, goes through a number of interesting chemical processes and finally emerges as flotation sulfur. There is reason to believe that the supply of sulfur required for spraying and dusting purposes v.dll be ample to meet the current season's n^sds at least. Is a Backyard Orchard Practical? V/ith limited space"a vail able for a fruit planting, there is much evidonce to show that the average individual in i,lassachusetts will obtain more satisfaction and more fruit for home use if he C'^nfines his efforts to small fruits such as strav/berries, raspberries and grapes than he vrill from a planting of tree fruits. Apples in particular seem to be subject to an unusual nuir.ber of troublesome pests v;hich require close attention and a thorough, ivell timed spray program if usable fruit is to b e obtained. Fully recognizing this fact, v;e are not only surprised but disturbed by recommendations recently released by an authority in fruit growing in one of the southern states. Speaking before the national Defense Gardening Conference in vVashington, December 20, on the subject, "More Fruit for Home Use on Our Fanns," the speaker made this statement: "Spraying prac- tices may be needed, especially for apples and grapes. In many districts and sections, however, these and other fruits m&Y be grown successfully without spraying." The writer is reasonably sure that the above mentioned sections do not include Massachusetts. The speaker also made this sta.te- ment; "Tree fruits such as apples, pears, peaches, plums and cherries, should occupy a prominent place in the home fruit garden. They should, of course, be supplemented by bush fruits, grapes and strawberries." Vvhile we cannot speak for the southern state in which this advice may be in order, under our conditions bush fruits, grapes and strawberries should come first in the backyard planting. Under no circumstances would we ad- vise the planting of apple trees in the backyard unless the owner is not only av/are of the pest situation, but is equipped to do something about it. Sound Mvice on Spraying Equipment The follc^ing suggestions come from one of the manufacturers of spraying equipment. Just at this season the advice is most timely, and should be heeded by every fruit grower, "Defense calls for extra care of your sprayer equipment. So many people still do not realize the seriousness of our national situation from an industrial viewpoint. There are still too many drifting along, business as usual, hoping the war v/ill not affect them. The plain facts are that v;ar production is going to require most of the available manufacturing of this country, 'i.hat little manufacturing is left will be applied to actual necessities. The old sprayers, now in service, must be kept running for it v;ill be impossible to build enough new ones during the ivar. You must make your present equipment run and you must give it every possible care to keep it running without using any more parts than can absolutely be helped* W.e are all saving our tires by driving feiver miles and at slov;er speeds. Let's save our sprayers by using them only when absolutely neces- sary and with no higher pressure than necessary. Let's take extra good care of them — keep them stored out of the weather when not in use — flush pump v/ith clear water after spraying-^-don't let it freeze up — stop and take time to make necessary adjustments when we see something needing attention — adjust tension of chains and V-Belts to save v/ear — don't run with regulator chattering — be more careful starting and stopping, when throwing the tractor in and out of gear — be especially attentive to oiling and greasing — in short, take care of your machine as thoughjou would never get another. Vie may soon have the same restrictions on spray hose that we now have on tires. Avoid accidentally rubbing on wheels and sharp rocks, do not kink, and keep it out of the sun when not in use. Many accessories, especially spray guns, are made of brass and aluminum--take care of those you have for there may not be metal available for more. Vfastefulness and carelessness is unpatriotic and a crime against the country almost as much as actual sabotage. In the past it has only cost the man who is careless, i but now it is different — money will not buy replacements which do not exist. Everyone of us must do our part to conserve our country's resources, and that includes sprayers. Keep them oiled--Keep them running. Pear Wood Needed for Umbrella 'Handles A request has just been received that we assist in locating a source of supply of bending stock for umbrella handles. Pear wood is one of the kinds mentioned and the most desirable size is a sprout or limb ap- proximately 7/8 to 1 inch in diameter which the concern cuts into 12 inch lengths. Green stock is preferred. The material used in these handles was formerly imported from Japan and that supply will probably be curtailed for some time. Any fruit grower interested in this new market for pear wood should get in touch with R. B. Parmenter, Extension Forester, M.S.C., Am- herst, Mass. Nev/ Beach Plum Project The last session of the legislature appropriated ^bOO for inves- tigational work with the Beach Plum. The prosecution of this project has been assigned to the Pomology Department and J. S. Bailey has been given immediate charge. Early in January, Prof. Bailey visited Barnstable County and Martha's Vineyard and conferred with those interested in the industry. He found several problems which are worthy of study. The selection of superior varieties from the various types along the coast, methods of propagation, pruning, fertilization and pest control, are some of the problems in need of investigation. A program, soon to be outlined on the basis of these observations, should yield results of value to the industry. J. K. Shaw Do You Know That high school students harvested many of the apples grov/n in V.'ashington last season? V.Tien a serious labor shortage developed at harvest time in the 'Venatchee-Okanogan apple belt, the high schools closed and- 90^ of the students v;ent into the orchards and packing houses. Seventy-four pupils of the Entiat (ViTashington) High School earned $4,351.60, according to "Better Fruit." - R. A. Van Meter How many varieties of apples there are? Ragan's List of Variety Karnes appearing in American publications from 1804 to 1904 includes 14,284 names. About one-half of these names are considered as synonyms. Evident- ly, about 7,000 names of distinct varieties of apples were published during that one hundred year period. J. K. Shaw That a recent Farmers' Bulletin discusses 19 parasitic, 10 non- parasitic and 10 virus diseases of potatoes, a total of 39? The plight of the potato grower seems to be getting tougher and tougher. Not many years ago he was confronted Y.'ith only two diseases, early and late blight. J.K.S. That losses in unpacked colonies of bees in Ohio are so severe that honey production is unprofitable in tv/o years out of five? The sit- uation may be similar in some sections of Massachusetts. In Ohio, it has been found that, with normal strength colonies having good and sufficient stores and pollen reserves, winter losses can be practically eliminated by supplying insulation equal to 4 inches on the sides and ends, 2 inches on the bottom, and 8 inches on the top of the hives. L. Southwick That the use of ozone at a one or two parts per million concen- tration for an hour each day will prevent the development of mold in stor- ages? It Vvdll also retard tiie development of scab, rots, and scald. L.S. That the different "fractions" of soil water freeze at different temperatures? Free or gravitational water which moves dovmward in the soil readily un'de'r~the Trifluence of gravity freezes at or above 29.3° F., most of the capillary water between 29,3° F. and 24.8° F. , while the colloidally absorbed or combined vmter does not freeze even at a temper- ature of 100" F. below zercT]! fTTis latter water is never available to plants. L.S. That boron is icn-own to occur in 56 different minerals? The only T^idely distributed one is tourmaline, a borosilicate of iron and aluminum. Vjhen this mineral weathers, boron is washed out in tlie form of borates which adcumulate in solution in lakes and oceans. L.S. That seleniium is the only mineral element definitely known to be absorbed from the soil by plants in sufficient quantities to make them lethal or deadly ti^ animals? This is the cause of "alkali disease" of livestock in the V»est. L.S. That a mature apple tree will produce, on the average, about 3 pounds of carbohydrates a day throughout the growing season? In clear vreather about half the daily output is produced between 9:30 A.M. and 2:30 P.M., according to A. J. Heinicke of Cornell University. He found that dark green leaves produce 2 to 4 times as much as light green or yellowish leaves, L.S. -6- That Webster defines "bruise" as follov;s: "to batter, contuse, injure, pound, break, pestle or maltreat? Even Ben Davis must succumb ■ from such treatment. L.S. Tliat Jonathan, PUiode Island Greening, King and Rome Beauty are more susceptible to arsenical injury than Mcintosh, V^ealthy, and Delicious? This was reported from Michigan where the recommendation for prevention of injury is the inclusion of a 1-4-100 or a 2-4-100 zinc sulfate-lime mixture to sprays containing arsenical s beginning two weeks after calj/-x. L.S. How to file a pruning saw? The writer has a good supply of a manual dealing with the care of various kinds of saws, prepared by a na- tionally known saw manufacturer. A postcard will brin^ a copy to your work- shop. Just ask for the Saw Manual. . That a total of 498 plants have been patented during the past 10 years? Of this number, 356 are on flov;ers, 99 on fruits and nuts, 23 on ornaraental s , and 20 on miscellaneous plants. Rose patents alone number 246. Fruit patents are distributed as follows: peach-27; apple-13; cherry, plum and strawberry-7 each; grape, orange and nectarine-4 each; pear-3, raspberry, blackberry, dewberry, grapefruit, lemon, lime, and pomegranate-1 each. The largest number of plant patents granted in any one year since 1931 was 85 in 1940-; the smallest number was 32 in 1934. The Peach C rop for J^9 42 The prospects for a peach crop in the College orchard are very poor. A survey made January 28 showed the percentage of live buds as follows: Elberta 0 Golden East 7 Carman 38 Red Rose 0 Valiant 7 Buttercup 80 Sungold 1 Polly 15 Oriole 80 Golden Globe 5 Veteran 20 Hale 6 Cumberland 28 Due to the late, wannfall the buds are very much more advanced than usual for this time of year. It is, therefore, not strange that they should succumb to higher temperatures than usual. The lov/est official tem- perature for Amherst was -13° F. on January 8. A thermograph near the orchard on the same date registered -10° F. Although there are still enough buQs on some varieties for a good crop, the winter is not over yet. Y/e won'tj "harvest any peaches" 'til after Y^'ashington' s birthday, J. S. Bailey Arsenical Injury in Young Peach Trees Growing on Old Apple Land In an article on the subject of arsenic toxicity in the soil, E. C. Blodgett describes a poisoning of young peach, apricot and Italian prune trees in Idaho caused by arsenioal residues in old apple orchard soilsi The symptoms included leaf spotting, shot-holing and premature defoliation, accompanied in pronounced cases by a crop of small, bitter fruits. Injury was greatest during the first two or three years following setting of the young orchard, and became progressively milder as the trees grew older and as the roots grew deeper into the soil. The disease was readily reproduced artificially by (l) setting young peach trees in pails of soil taken from -7- affected orchards and (2) by growing, trees in soils taken from non-orchard sitesto which lead arsen&te was added in various d03ag,es. Other trees ^rovm as in (2) except that no lead arsenate wag added, remained normal. 0. C. Boyd Food for Thought in Selling Apples in an aadress~at the annual meeting of the Virginia State Horti- cultural Society, V. E, Gardner of Llichigan State Golle^:e made this in- teresting statement: "If the apples are a bit under colored, variable in size and snape, if they show a good many bruises, in brief if tliey are below par, they are left on tlie shelf and the oranges and grapefruit are purchased. This is corroborated by the experience of chain store system buyers and super-market operators. They say that Vifhen they have really fancy, highly attractive apples to sell, not only do they sell them in larger x'-olume than oranges and grapefruit, but they can and do sell them at higher prices and the citrus fruits must be priced in proper relation to them in order to b e moved. On the other hand, if the apples are below par, it is the citrus fruits that set the selling pace and set the price and the apples must be priced down in order to sell at all," L. Southwick Fruit Production - 1942 normal growing conditions in 1942 will probably result in a smaller production of apples, peaches, pears, plums, and prunes, and a larger output of apricots, cherries, grapes, strav/berries, oranges, grape- fruit, and lemons than in 1941, according to the January issue of The Agricultural Situation. L. Southwick Apple Varieties in Nova Scotia A recent survey of orchards in the Annapolis Valley of Nova Scotia,. including 30,368 acres, reveals that the heaviest planted single variety is Stark. This is followed in order by V^agener, Baldv;in, Ben Davis, Golden Russeti,'. King and Red King, Northern Spy, Gravenstein, Gano, Ribston, Mcintosh, Cox Orange, and Blenheim. Total Llcintosh trees numbered only 55,916 whereas there were 184,155 Stark trees. In recent plantings, Wag- ener holds first place, followed in order ^Golden Russet, Llclntosh, red sports of Delicious, Cortland, and Crimson Gravenstein. Some 40,000 trees vj-ere removed by organized tractor pulling in 1940. About half of these were 51 years of age or over, about a quarter 41-50 and a quarter 21-40. By variety the heaviest pulling was in Baldwin, Nnnpariel, Gravenstein, Stark and the odd varieties. The report of the Nova Scotia Apple Llarketing Board for the 1939-40 crop season lists some 214 varieties of apples handled during that season. L. Southwick Vfeather Conditions Uere and in England It is interesting to note tiTe considerable differences in rainfall and sunshine in a fruit growing section of England and in Massachusetts. The figures here given represent the normals or the average conditions over a period of years' as observed at Amherst, Massachusetts, and at Kent, England. Precipitation in Inches Hours of Sunshine April - September AJinual Annual Amherst 23,1 43.7 2353 Kent 11.8 26.2 1480 ■8- Although irrigation has given favorable results in liinited trials in England, drought conditions seem to be mentioned less fre- quently by the English than by Massachusetts farmers. The maritime climate of England is probably responsible. Besides less sunshine, temperatures ran^e lower during the growing season, and humidity^may be higher than in most parts of Massachusetts. There is reason to be- lieve that a total rainfall of only 11.8 inches from April through Sept- ember would be inadequate on many Massachusetts fruit farms. L. Southwick Rab bit In j ury A newly developed repellent for preventing rabbit damage to fruit trees v/as mentioned in December Fruit Kotes. This repellent is a fruit tree coating and is effective against cottontails. It has been recommended by v;orkers in the Michigan Agricultural Experiment Station. More than 200 materials or :aixtures have been tested since 1937. The only repellent that proved to be safe on trees as well as effective against rabbits v»-as a mix- ture of rosin and ethyl alcohol as stated in Fruit Notes. Cheaper grades of rosin and of denatured commercial ethyl alcohol were found to be as satisfactory as the higher grades. Seven pounds of rosin are dissolved in one gallon of alcohol (slightly more than one part of rosin to one part of alcohol by weight). This may take up to 24 hours in a warm room. The container should be closed to prevent evaporation and to allow shaking. iJo heat should be appliedl Treated trees vrill turn white but this does not'~change the eTfectiveness nor does it harm the trees. The repellent should be applied in the fall and only when the bark is dry. One applica- tion protects all winter. Yie have not tried this repellent as yet at the State College. L. Southwick Classification and Taxation of Forest Lands and Forest Products The'T.'aw covering the taxation of forest lands was ainended last year by the Massachusetts Legislature as follov^s: All forest land, having an assessed valuation not in excess of ^25 per acre for land and growth became automatically classified January 1st, 1942. The assessors notify owners of forest land' on or "before March 1st, 1942, that such land is classified. If the land is not classified, the owner can appeal to the State Forester for a hearing. The owner of classified forest land may cut, free of tax, wood or timber therefrom for his ovm use or for the use of a tenant, not to exceed s;25 in stumpage value. On any amount above this $25 he must pay a products tax of such percentage of the stuiapage value as is set forth in the following schedule: VJ"ood and Timber Cut from Land Classified — Less than three years, \%; three to six years, 2^; six to nine years, 3%, nine to twelve years, 4^; tv/elve to fifteen years, 5^; fifteen years or more, 6^. The ovmer shall make a return to the assessors before April 1st, showing the amount of wood and timber cut from classified land during the preceding c'ttLendar year. A form for this will be provided.

Semi -Dwarf Apple Trees ~ There seems to be a grov;ing interest among fruit growers in semi- dwarf apple trees. The most promising stocks for such trees are Mailing I, rv and VII. Trees on these stocks maybe expected to reach roughly tvro- tiiirds the height and three-fourths the spread of trees on seedling roots. They groitr nearly or quite as rapidly as ordinary trees until they begin to bear. The age of bearing will depend on the variety and on cultural prac- tices, but v/ill be from two to five years sooner than if the trees v;ere on seedling stocks. When they begin to bear commercial crops, growth, es- pecially in height, is checked. They can be planted somev/hat closer than standard trees but should be allovred from 20 to 35 feet according to var- iety and soil. The fruit on semi-dwarf trees is practically the same as that of standard trees though we expect that high color may be more readily attained. Trees may prove shorter lived and may suffer more from poor growing conditions. We believe that acre yields from suitably spaced trees will be greater. Unfortunately, trees on these stocks carmot now be gen- erally obtained except at rather high prices, but we expect that this will not be true in future years. J. K. Shaw Correction In a recent issue of Fruit Notes, it was stated that field mice do not attack the cultivated blueberry. This statement is not entirely correct. There are a few well-authenticated cases of mouse girdling of blueberry bushes, although Yi. W. Dykstra of the Fish and Vv'ildlife Service says that injury to blueberries is uncommon. It is most likely to occur on young shoots and on bushes heavily mulched with hay. ¥«here mulch is used, hovrever, control should not be difficult since mouse "runs" are easily located and baited. There is some evidence that sawdust may be unattractive to meadow mice. L. Southwick Boysenberries in Massachusetts Although the Boysenberry is not particularly well adapted to our climate, it seems that this nev; fruit has done fairly well in isolated in- stances in this state. O^e report from a grower in Barnstable County tells of a 300-quart crop grown last season. The writer v.'ill appreciate hearing from anyone who has experienced some success v;ith this fruit. L.

Some of the materials normally used in fertilizers were previously transported by ships which are not now available. Plans are under way for monthly ra- tioning of nitrate of soda by states at a fixed price, plus transportation. Early shipments will go into the southern states. Supplies of superphosphate in 1943 may be curtailed, since future shipments of phosphate rock from Florida will involve rail instead of v;ater transportation.

In orchards showing a scanty cover crop, this may be a move in the ri£;ht direction. Spray iiaterials. A recent release from the National Apple Insti- tute readsl "Provision has been made for a sufficient supply of lead arsenate. There will be enough copper sulfate. Plenty of raw sulfur exists in this country for lime sulfur solutions, mixed sulfur dusts, and sulfur compounds, the only question being whether production in the manufacturing plants can stay on these materials. Nicotine sulfate has been placed under price con- trol at a higher price with the object of insuring sufficient production." Equipnent and Ilachinery. Production of new sprayers and other machinery has oeen cut to approximately 83^^ of the 1940 supply. But produc- tion of repair parts and replacements will be 140^^ of 1940. This includes rubber hose. The need for early overhauling of the sprayer cannot be over- stressed. A completely rejuvenated power sprayer may be exceedingly useful if, and when, emergency fire fighting equipment is needed. (One grovier, faced with a menacing fire, saved his farm buildings by having a sprayer in readiness.) As the stock of repair parts on the dealer's shelves is depleted, he has a better chance for replenislunent if he has actual orders on hand. Shipments from distcuit points will move slovirly, and late orders may not be filled on time. All worn parts should be replaced at once. Boxes. Quoting from a recent Washington telegram, "Re your tele- gram February 3, manufacturer may accept orders from farmers for boxes with- out jeopardizing his defense rating under preference rating orders." Ammunition containers and other vrar items have first call on box manufactur- ers. A few of them, hovrever, are apparently able to turn out some box shook. Box nails are scarce and are becoming more so. You v;ill have a better chance of getting nails for the coming season if you order from your usual supplier at once. In case he has none, try somewhere else. Apple growers may find it advantageous to nail boxes at the farm when other work is not pressing. 1942 Apple Spray Chart Barring unexpected delays in printing, the 1942 Apple Spray Chart should be available soon. This season for the first time, either the Dormant or Delayed Dormant spray is recommended, the choice depending upon pests present. If rosy aphis is a serious problem, a DN spray or a DN Oil Spray at the dormant stage is reconiaended. But if red mite is the principal early season pest, the usual Delayed Dormant application of Misoible Oil or Oil Emulsion is in order. A Contrast in Nursery Advertising The following description of the Dresden strawberry was seen in a recent nursery catalog: "V.'e were disappointed with the Dresden last summer. It set a large crop of berries, but they v/ere of poor color and too soft for a market berry. They did not come near the standard of Howard 17, Catskill, or Pathfinder. We will not set any Dresden this year. However, some of the other plant grovjers speak very highly of the Dresden. For any who v;ant to try them out, we have some nice plants." This statenier.t, by its .frankness, is a narked contrast to frequent extravagant statements in nursery advertising, v/hich ■aim to confuse and mis- lead rather than to present the facts fairly. The latter t'^'pe of advertising is illustrated by the folloxving statement taken from a recent issue of a prominent periodical: "Bearing age plants yield in 60 days. Have plenty of fruit to eat and sell this year. Send for these fruit- plants ready to bear first season. Blueberries, boysenberries, strawberries, raspberries, apples, peaches ." The extravagance of these statements' would be amusing except for the fact that some people, whose knowledge of the bearing habit of fruits is limited, are going to be lured into buying plants v/hich will prove a great disappointment. The nursery v/ith the Dresden strawberry should have a host of friends, v/hile the other nursery merits nothing but condemnation. ' '•■; " 0. C. Roberts Test Orchard Soils for Acidity " If the soil is very acid certain necessary plant food elements be- come locked up, and are therefore unavailable. If the pH is as lov; as 5, an application of ground limestone will tend to render more available some of the mineral elements for which we pay h^rd earned cash. Two examples from veget- able investigations will help to illustrate this point. (1) V. A. Tiedjens of the N. J. Agr. Exp. Sta., says, "Acid soils tend to fix phosphoric acid. For this reason, if v/e must farm acid soils, v/e must use a 1-2-1 or a 1-3-1 fertilizer ratio so that the plants will receive sufficient phosphoric acid. V«''ith sufficient lime in the soil, a 1-1-1 or a 1-1-2 ratio would be suitable because more of the phosphoric acid v.'ould be available. (2) Results of applying increasing amounts of -potash in growing peppers on limed and unlimed soils in Hew Jersey, are strikingly shov/n in the follov.'ing table; Fertilizer Unlimed Limed (1000 lbs. per acre) (Yield, bu. per acre) (Yield, bu. per acre) 5-10-0 268 297 5-10-5 268 324 5-10-10 329 408 5-10-15 356 . 405 5-10-20 345 359 From these figures it is apparent that lime increased the efficiency of the potash in the mixed fertilizer. Lime is relatively- inexpensive. It may be very much needed in your orchard. The cover crop is a good indicator of soil acidity. Soil samples should be taken in each block since they are likely to vary in degree of acidity. ^\nd if the soil in a given area tests pH 5 or lower, an application of ground limestone this spring may prove a very profitable investment. Do You Know ■ That apple pie holds top rank in the army camps of the U. S.? A poll of the various camps conducted by the V,'ar Department shov;s that apple pie is the favorite dessert of men in khaki. Ice cream is a close second to apple pie. Others in order of preference are as follows; Doughnuts, chocolate cake, cherry pie, coconut cake, mince pie, fruit cobbler, banana puddin^,. butterscotch pudding and rice pudding. Prunes and ither dried fruits, the army release says, are still popular in spite oi the stories told by veterans of the other Vi'orld V;"ar, That the edible portion of an apple is in rea.Vity "a fleshy stem"? The pineapple, however, is the crovraing achievement in ■•h'- development of a fruit. The central core, v;hich is commonly remtJved, is -u.ilogous to tlie trunk of a tree. The segments v»'hich radiate from this centrul c ore are analogous to side branches of a tree and on these branches are borne , :t flowers or "eyes" Vv-hich are also coniiaonly removed v;hen the pineapple is prepared for the table.

These figures are offered by a California automobile club. That tlie ort^nge crop of the United States in 1941 was 84,414,000 boxes compared to 84,082,000 boxes in 1940. The grapefruit crops for the two years were 41,440,000 and 43,033,000 boxes, respectively. The lemon crops were 14,220,000 and 17,099,000 boxes, respectively. That a group of apple growers in the V-enatchee Valley in V^'ashington have formed a cooperative ufiit to buy and operate a brush shredder. This machine, equipped v/it?i a 90 K. P. motor is scneduled to arrive early in Feb- ruary. Under the AAA, the government pays i.3. a ton for shredded brush left in the orchard. Originators of the unit believe this payment v/ill almost pay for the operation of the machine aside from the advantage of adding humus to the orchard soil. That the Dor sett variety of strawberry is a cross betv/een the Howard 17 (Premier) and an English variety, the Royal Sovereign? That a sawdust mulch is provin^, an excellent mulch material for blueberry plants? In one experiment blueberries grew ten ti.nes as much under a sav;dust mulch as under no mulch, and tv/ice as much under sawdust as under a strav/ or hay mulch. This report from the ^Werican Fruit Grovaer indicates these values of mulching: Improved moisture conditions, lower and more uniform soil te;riperatures, and no cultivation to disturb the shallow rioted blueberry plants.

Adopting the system commonly used by florists, a tele- graphic agency now has ab^ut 1,000 members scattered over the country v/ho are supplied with high quality apples f-^r prTapt delivery.

Recent work of the South Haven, I'lich. Exp. Sta. shows that bridge grafting peach trees with either peach or plu:n scions v.-as unsucc^issful , The peach scions refused to "take", A reasonable percentage of the plun scions grew but the tops above ther.i died later. That it is likely to be unprofitable to bridge graft girdled apple trees which are under 2^- inches in diameter? Observations and grov.-th .Measure- ments made in a Michigan 17-year old orchard v/here part "f the trees had been bridge grafted and part of thei.; cut off and cleft grafted following girdling v;aen about 2 to 2-|V inches in dianeter, indicates that cleft grafting is dis- tinctly preferable for tre'.s that size or smaller. That slopes as steep as 55^0 in the Finger Lake District of Uev; York have been used for vineyards? According to A, 3. Beauiaont, soiae of these vineyards have been abandoned because of severe erosion. Practical neth'^ds of erosion c-^ntrol are now being developed. That California leads all other states in nunber of fan.is under three acres? 6,476 farns are in that class.

That Bor-^n is proving successful in preventing cracking of cherries. Used successfully for several years to prevent celery steiTi crack and si-nilar difficulties, it v/as also used successfully this year to prevent cracking of carrots. Boron appears to give elasticity to plant cell .aeiubranes and for that reason tests are being made in prune and cherry orchards to prevent cracking of these fruits. In one cherry orchard, the cracking was reduced to a negligible aiaount where borax v/as used at 30 lbs. per cere. Prune cracking was reduced fror.i 25$^ on untreated plots to 9/:, wh'jre boron was applied; Do You Read the Annual Report? The Annual Report of the Experiment Station is seen by few of our fruit grov/ers. It is in bulletin fom and has increased in size from 54 to 108 pages in the last ten years. It contains brief statements concerning practically all the research and ccitrol work of the Station. The report covers the year ending Novonber 30 and is prepared shortly after that date. It is not available in printed form much before :.iid-suM.ner. Anyone seeing this Report for the first time v;ill be astonished at the aiaount and diversity of the re- search work going on at the Experiment Station. The edition is limited but a copy will be available to any citizen of the Coim.ionv/ealth.

Agr. Exp. Sta. in Amiierst. This work has included an evaluation of different clarifying methods for apple juice and blends of Massachusetts apples suit- able for juice. In Massachusetts the Mcintosh is the most important commercial variety. Unfortunately, the juice of the Mcintosh has a rather insipid flavor and must be blended with other varieties if used in the manufacture of a palatable apple juice. Tests have been made to determine the maximum amount of liclntosh juice that can be blended with Baldwin or Delicious var- ieties to yield a satisfactory commercial product. It xsas found that blends containing up to 60% of Mcintosh juice yielded a pleasing product. In such blends it is not recomip.ended that over 25)j Delicious apples be used owing to their strong- aromatic flavor. \'^ . B. Esselen They Say It '..orks 1. "Hard" Cider, The problem of keeping cider for year round con- sumption has been solved by iluckley Brothers of l^a^Taesburg, Ohio. Acting on the suggestion of T. K. Tressler of the Hew York State Experiment Station v;ho says "Freezing is the ideal method of preserving apple juice," they are now freezing annually 110 fifty-gallon barrels of cider into "cider ice." They use only good, sound apples. The cid^^r is made in a commercial press where press cloths and other materials are kept scrupulously clean. An average blend consists of Grimes, Baldwin and Delicious. After pressing, the cider is allovred to stand for 24 hours to allow any sediment to settle out, and is them passed through a screen into 50-gallon barrels. Seven to 10)b "head room" is allov.'ed so that the barrels vrill not burst when the cider is frozen. Quick freezing is accomplished at a temperature of 5 to 10 degrees below zero. It is then put into storage until needed. Thawing takes several days after which the cider is poured into a dispensing unit which keeps it at 38° to avoid fermentation. During the fair season their cider dispensing unit is placed on a truck and hauled around to summer fairs vrhere cider is sold by the glass. Last year 5,000 bushels of apples were sold by these men via the pressing, freezing, storing and "selling at leisure" route. Here is a new method of making "hard" cider, but not the kind reported to be popular v;hen stone walls were being built in grandfather's day, 2. Peach Borers, Harry Seagraves of V.est Heivbury is demonstrating a nevr way of controlling peach borers. He avoids the task of digging around the trunks of trees, "worming" with knife and v/ire, and the commonly recom- mended chemical treatment, by placing a copper or bronze mosquito wire mesh guard around his trees at planting time. He writes "Many window screen manu- facturers near the ocean use only copper or bronze wire. Often screens come back for repairs having only a small break and the old screen is sold as junk. While this screen is not as good as new, much of it v/ill last five or six years. In fact, v/e have had some on tees for more than ten years. The soft copper screen lasts longer as it is not so apt to break at the creases, as hardened bronze. 17e cut a piece of screen 18" x 18" and fold it to 7-|-" x 18" allowing 3 inches to lap over. Using a short piece of board,' \.'e flatten out -7- the creases, and when the whip is planted, v;e slip the flattened cylinder dovfi: over it and let it extend two or three inches into the dirt in such manner that the moth camiot reach the tree. The guard v/ill aiever girdle the tree but will always be ti^ht around the trunk and will last until the tree is five inches in dianeter. Vdiile we do not have quite so many borers as in orchards fartlier south, we have plenty of orchards nearby which are badly infested. But v;e have not seen a single borer in our 500 trees, all of which were planted with window screennetting guards. 3. Storage Scald. Prevention of storage scald in the Cortland variety has been carefully studied by workers at the Rhode Island Agricul- tural Experiment Station. They find that the date of harvest has a definite relationship to the amount of scald. Cortland apples were harvested on six different dates in the Station orchard and the a:-.iount of scald in each lot observed. The results were as follows: The percentage figure in each case represents the portion of that lot which was entirely free from storage scald, Sept. 16, 5=0? Sept. 23, 21^'p; Sept. 30, 85);; Oct. 7, 95%; and Oct. 14, 100^. The late harvested fruit also has much better color and was superior in all respects. Ilulching Experiments at the State College A mulch of glass wool is being used under certain trees in the State College orchard in Amherst to determine its effect on plant nutrients in the soil. For some time it has been known that nitrates and replaceable potash are found in orchard soils beneath a hay mulch. Ey means of the glass wool an attempt v;ill be made to determine whether or not these mineral nutrients are due solely to the decomposition of the mulch or to soil condi- tions brought about by mulching. Two 30-year-old ;.icIntosh trees grown under cultivation have been mulched v;ith hay, two with glass wool, and tv/o are still under cultivation. Tv;o trenches were recently dug under each tree and soil samples at several depths were taken. These samples are now being analyzed to determine total and available nutrients. Similar saraples will be taken one or more times each year and analyzed. In another plot where cultivation and mulching are under comparison, heavy mulching vras begini in 1922. Rootlets are much more abundant Just be- neath the mulch than in surface areas under cultivation or sod. Doubtless there are three conditions which favor such root development, - (1) better and more uniform moisture supply, (2) more readily available nutrients, and (3) better aeration. The growth of these trees last sui/iiier was remarkably good and the crop was the largest of any of the seven plots in the orchard. There have never been any signs of nitrogen deficiency following these liberal applications of v;aste hay. Ko fertilizer other than the mulch has been applied for twenty years. J. K. Shaw An Old LIulching Expe r imo n t There is nothing new under the sun. In Vfisconsin Bui. 87, published in 1901, Professor E. S. Goff tells of mulching a small plum orchard with marsh hay applied six inches deep. The results were very satisfactory. The grass (except quack grass) was killed, and the tree roots were induced to grow almost to the top of the ground. This, he feared, made the trees more subject to winter killing. in the severs winters of Wisconsin, He notes that the mulched trees had more healthy foliage and the size and quality of the fruit v;as increased. J. K. Shaw -3- Guard the Supply of Farm Llaimres Farmers are ur^ed to make full use of fertility from farm manures. Accustomed supplies of commercial fertilizers are being interrupted by v/ar conditions and a definite shortage of some ingredients is apparent. If farmers are to maintain or increase the yield of needed products, efforts would seem wisely spent in conserving much of the manure fertility which is wasted at present. Considerable quantities of poultry manure are still dumped for want of better use. Despite the labor cost of collecting and distributing, this material should be salvaged as one of the richest nitro- gen manures for crop use. Poultry-men having surplus manure should notify their county agricultural agent who v»rill pass this information on to farm- ers needing it. Almost half the crop producing value of cow manure is contributed by the urine which contains about half the nitrogen and three quarters of the potash. Failure to conserve this liquid portion of manure is undoubtedly the main cause of loss in handling manure. Much can be done to save this important loss of urine by ample use of absorbent material in the gutter and tlien spreading daily on the land where possible. If manure is stored, a pit with concrete base will prevent loss later by leaching from the pile. If excess water accumulates in the pit from rainfall, a roof shelter may be added. Since a scarcity of bedding material no doubt is the chief reason for this loss, farmers should seek a supply wherever possible. Sawdust and swale grass hay are useful among other items for bedding. R. W. Donaldson War-time Apple Prices ViT. E. Piper of the Division of Markets submits this interesting analysis of apple prices during the First Vvorld War: "Host growers, old enough to remember that period, recall the boom prices during certain por- tions of the Vvar years. Recollections, however, as to the exact time of high prices are naturally hazy. Y.'e have consequently dug out some figures to tell the story in as condensed form as possible. Annual production, quantity exported, and average U. S. prices paid to farmers at intervals of three months during each season, are shown below. Prices U.S. Crop Exports (Ave. to farmers J cts. per bu Season (bu.) (bbls.) Sept. Dec.

Actual volume is, therefore, not comparable with figures for recent years, but for all practical purposes they give a reasonably accurate picture of the relative size of the crop during the various years within the war period. The same may be more or less true of the price figures. Being national averages of prices paid to farmers they would differ -9- somewhat from local market prices in dollars and cents, but on a propor- tional basis they reflect the price chan^^es during the v;ar years." YJar-time Supplies for Beekeepers ' . . In order to provide sufficient bees for pollination of the expected increased amounts of fruits and vegetables, and to meet the demands for honey as a sugar substitute, beekeepers are urged to increase both the number of colonies and the amount of honey produced. In Kew York, plans are being made todnuble the 1941 honey crop. Massachusetts beekeepers must do their share. In this connection beekeepers will be interested in the following information just received concerning commodities needed in the industry: Sugar. Bee producers and apiarists can secure 80^ j of the sugar they used last year' on a month by month basis. This is according to General Preference Order M-55 as amended. ^ In addition, if this does not take care of present needs or if the beekeeper did not feed sugar last year but needs some this year, he should v;rite or wire. Ilr. A. E. Bowman, Chief, Sugar Sec- tion, War Production Board, Vj'ashington, D. C. Included should be the, follow- ing: Amount o-f, sugar already obtained under General Preference Ruling 1,1-55. Number of colonies under production. Amount of sugar needed in terms of 100-pound bags.' The specific urgency (in number of days) as to when the sugar must be delivered. The name of the dealer from v;-hom purchase is to be made. Beekeepers should not abuse this privilege v;hic'h has been granted on the basis that a beekeeper uses a small amount of sugar to produce a larger amount of honey. Tin. The War Production Board has made provision for the beekeeping industry to obtain all the tin cans it will need in sizes of 5-pound and larger. Tin containers in unlimited quantities in the sizes stated will be made available as long as the supply lasts. Every effort should be made to use glass and other types of containers as much as possible notwithstand- ing the above. Tires. Beekeepers will be treated the same as other farmers as regards tires. It should be explained to the local tire rationing board that the V'lar Production Board recognizes the importance of the industry and this is well attested by the fact that provisions have been made for the in- dustry to obtain restricted materials such as sugar, tin, and other metals. F. R. Shaw Apple Tree Census Apple acreage in tlie United States has been decreasing rather stead- ily for about 30 years, according to a. recent study by Scoville and Cairipbell of Cornell University. The decrease intJie last decade was especially high, ajnounting to about 38;;^. In millions of trees, the numbers reported in 1920, 1930, and 1940 were 151.5, 115.3, and 71.7 respectively. In Nev; England alone, comparable figures vrere 8.5, 6.6, and 3,6. For comparison, in 1939 Massachusetts reported 1,408,872 trees of all ages. Production has not declined to tlie same extent as tree numbers, due to increased yields per tree. The average annual production, in millions of bushels, v;as reported as follows: 1910-1919, 190; 1920-1929, 163; 1930-1939, 157, -10- It is interesting to note that number of trees may not always be a good index of total yield. The state that boasts the largest commercial production is Washington, even though this state stands seventh in number of trees. The six states with largest average production for the last six years are, in order, as follows: Vfeshington, New York, Virginia, Pennsyl- vania, California and Michigan. IVashington averages roughly 28 million bushels per year; New York, 17; Michigan, 7; Massachusetts, 2. L. Southwick Compulsory Apple Maggot Control in Nova Scotia The latest report of the Apple Maggot Control Board (appointed by the Nova Scotia Fruit Growers' Association) v.'as presented in December, 1941, at the Annual Meeting of the Society held at Kentville, Nova Scotia. This shov/s vfhat is being done by an aroused group of growers in compelling ovmers of reglected trees to either spray or destroy them in the interest of the fruit growing industry. Inspectors made 5,275 visits in 1941. Owners of non-commercial trees were urged to have their trees removed free of charge by the Department of Agriculture. Yfhere ovv-ners fail to comply with the Board's orders, an inspector in eacli zone Virill destroy the trees at the owner's expense. "Before the danger period for spread of apple maggot comes around next year all delinquents will have been dealt v/ith." The Board is of the opinion that the firm attitude adopted during the past year has yielded substantial results and it is recommended that the regulations be rigorously enforced in 1942. L. Southwick Tree Pulling in Nova Scotia Tractor pulling of fruit trees, particularly apple trees, v/hich are deemed undesirable by their owners because of variety, condition, age, or location, has been carried out in Canada by the Government as a free service since 1938. Over 80,000 trees have been pulled. Ina recent report, it was stated that the cost of this service to the Government has been about 17 cents per tree. Further reduction of unprofitable trees is highly recom- mended. Under favorable circumstances, tree planting, including r epl anting of good sites, is advocated. Recommended varieties are Crimson Gravenstein, Mcintosh, Cortland, Red Delicious, Red Spy, and Red Rome. L. Southv/ick Guns, Tanlcs and — Apples Ajaerioa promises us guns, planes, tanks, ammunition — and food. All these are vital things and, among items of food, we would like to see apples prominently mentioned to take the place of our disappearing stocks. The Apple is the favorite cleansing and vitalizing element of food among all the classes, and the health of the nation would benefit considerably by a consignment of those attractive Apples to brighten the menu of busy people. V^e admit that in many ways vegetables — and especially ravif vegetables and salads--can per- form a similar function to the Apple, but in the so days of long hours and irregularity such foods_ cannot always* be prepared in time. There is alv;ays time to eat an Apple, and it is the-fcusiest people who need them. (Market Grower, Salesman, and Fruit Trader, London, England.) FRUIT NOTES Volume 6 Number 3 March, 1942. W. H.

He therefore suggests that fruit growers order bees early for pollinating purposes. The Box Situation An official in an Eastern box association writes: "The volume of defense business is increasing daily, and if growers wait until June or July to buy apple boxes they will probably have difficulty in obtaining sufficiertfc quantities. YIe are of the opinion that concerns which have made apple boxes in previous years will take care nf their regular box customers this year. Vt'e doubt if any manufacturer v;ill be interested in taking on new accounts but if growers will cooperate by placing orders at once, and taking delivery from now until picking season at the convenience of the manufacturers, and making satisfactory credit arrangements, we feel there will be no shortage." (A list of concei-ns manufacturing box shook in this area is available.) Quoting from the March 16 Seasonal Fruit Notes by li. A. Rollins, "The recent survey of 24 box manufacturers in southern New England shows that 16 are interested in making apple boxes. From the replies it is very evident that fruit grov/ers who need apple boxes for the 1942 crop should order early if they expect to have delivery by harvest time. Most of the box manufacturers prefer to furnish the boxes in shook to the fruit grov/er. This may mean that you will have to nail your own boxes this year even though you have not been accustomed to doing so. Show good judgment by ordering your box shook now and try to obtain one keg of 4d cement coated nails for each 1,000 box shook." Some enlightenment on the nail situation is found in this quotation from a letter written I.Iarch 4 by an official in a large hard^vare supply con- cern: "We have already received orders for nails for apple boxes for use next fall and these will be shipped in order of receipt. As you probably know, we are on a strict quota basis and we have no idea at this time how many kegs of apple box nails we will have available or for hovj many orders. Because our quotas are based on previous sales and because v;e are having many calls which we formerly did not have, and in view of the scarcity of nails, there isn't any question but what the supply will be inadequate. The only advice that v;e can give you is to get the orders in at once. You no ' doubt know that P-100 has been made available for farmers for repair of machinery. Vie believe that this authority has not been passed along for an operation item such as nails for apple boxes. But an A-10 under the present conditions is not adequate because the factory is filled with orders v;ith A-l-a priority, which take precedence," 1942 Spray Charts By the time March Fruit Notes is delivered, the 1942 Apple and Peach spray charts should be in the hands of your county agricultural agent for distribution. The Apple spray charts are again available on both cards and paper stock. The Peach spray charts are available on paper stock only. These new charts were examined and discussed for the first time at the Tri-County Meeting of fruit grov/ers held in Amherst on Monday, March 23. Do You Know That Baldwin apples were selling in Boston seventy years ago at five cents apiece? In the first issue of the Boston Globe published March 4, 1872 there appeared this item: "Good Baldwin apples are selling in England today for a penny apiece; here they are five cents, and from that upv/ards." That New England agriculture provides employnnent for over 600,000 men, women, and children on about 135,000 farms? In 1940 the cash returns to our farmers amounted to more than $.263,000,000. That more than 1000 tons of lead arsenate were sold in Massachusetts for incecticidal use in 1D41? If this material could be adiTiinistered individ- ually to the various chewing insects in minimum lethal doses, less than 1% of the amo-ont now used would probably be ample for the protection of our agri- cultural crops. That lists of reliable dealers in various kinds of fruit plants are available from your county agricultural agent or from the State College? In establishing a ne^v stra\;berry planting there are some advantages in getting northern grov.Ti plants, while the advantages of disease-free raspberry plants are v;ell ^recognized. That a poorly sprayed apple tree tends to grov; taller than a well sprayed tree? The downvirard pull on the branches of the latter nay be ten times as much as on the former, because fewer apples drop from the well sprayed tree before harvest time, and their average size is larger. A branch which bears a few undersized culls is hampered but little in its reach for the sky, while trie heavily laden branch is bent dov.niward to form a graceful arc, That the term "DK" is an abbreviation for dinitroorthocyclohexylphe- nol? No wonder the stuff has punch enough to knock out rosy aphis. Imagine a football player v>;ith a name like thati That apple roots are killed if the temperature of the soil in late win- ter drops to 10" ^^ ? In summer, the critical temperature is 26" F. This sit- uation emphasizes t!ie insulating effect of a layer of soil. Even though the air temperature drops to -10° F. for a day or tv;o in winter the soil a few inches below the surface may remain unfrozen. Under a heavy mulch, the tem- perature change is almost unbelievably slow. That poultry manure contains approximately the following amounts of plant nutrients per ton: nitrogen, 20 lbs.; phosphoric acid, 16 lbs.; potash, S lbs.? Stable manure contains more potash but less of the other two ingre- dients, or about 10 lbs., 5 lbs., and 10 lbs., respectively. That the average yield of strav;berries in all producing areas in the U. S. over a 10-year period is only 1532 quarts per acre? YJithan occasional Massachusetts grower producing more than 10,000 quarts per acre, it is apparent that the picking in somebody's strawberry patch must be "pretty thin." Txhat the tonnage of dried fruits in California amounts to as i.iuch as half a million tons annually? The 1939 figures reported in California Circ. No. 350 are as follows: apricots, 40,000 tons; figs, 25,000 tons; clingstone peaches, 4,000 tons, freestone peaches, 24,000 tons; pears, 7,700 t'-'ns; prunes, 134,000 tons; raisins, 239,500 tons. -4- |: That pear producti^vn in the U.S. has almost doubled in the last 2,0 ears? The increase has occurred largely in the Pacific C<^ast States, where urin^ the 5-yr. period, 133G-40, 2/3 of the total iJ^S. pear crop was proauced. That Calif ornians aonsune, * 18 pounds of avocados per person each year compared with l/4 of a pound per capita for the rest of the country? It is this disparity which makes avocado growers alert to possibilities. of their product and which raalces many forecasters wonder if this is nof the next nev; h'^rticultural crop for development. (This item and the two following, are quoted from Horticultural iTotes by H. B. Tukey). That one of the two original Vn'ashington navel orange trees, from which the Washington navel arange industry sprang, is still growing and fruiting in its protected enclosure at Riverside, California? That just prior to the onset of the present v;ar, Canada exported approximately 50^j of its commercial apple production,. U. S. 12jo, Australia 50%, Chile 50/,, and Argentina 20;;o2 These figures indicate the dependence of the apple industry upon, free movement into export channels. That approximately ,10;^^ (16,000,000 bu.) of the national apple crop is made into cider? Afo (6j500,000 bu.) is used as 'dried .apples, 5'/, (5,000,000 bii.) for canned apples, 1.2^^ (2,000,000 bu.) for canned apple sauce, and l.l^o (1,800,000 bu.) for brandy. These 5 by-products account for 19.3>o (31,300,000 bu.) , That, in 1941, 120,500 acres in'tliis country were devoted to growing alsike clover "seed, 564,,-500 to sweet clover seed, 368,400 to timothy seed, 791,000 t'o alfalfa seed, 801,900 "to lespedeza seed, and 1,445,900 to red clo- ver seed? The lespedeza seed crop constituted moi-e than a fourth of the total grass and clover seed produced in the United States in 194r» L. Southwick That, in 1941, the five states leading in strav^berry production v;ere Arkansas, Louisiana, Oregon, Llichigan and Tennessee? Arkansas produced 1,540,000 (32 qt.) crates from 19,500 acres, or 79 crates per acre on the average. Yield per acre varied from 30 crates in Kansas to 150 in the south- ern district of California. L. S. That it takes about four pounds of fresh grapes to make one pound of dried raisins? L. S. That the number of apple trees increased from 120 million in 1890 to 217 million by 1910, and then decreased until in 1940, only 71.7 million trees were reported? L. S. That production per bearing tree averages more than four bushels in the entire TVestern apple section, ab^ut 7 bushels in Y;'ashington, about 1.2 bushels in the Mississippi drainage basin, and 1,7 bushels in the Northeastern and Central Atlantic sections? L. S. That fungicidal applications a re not generally required in commercial apple orchards in the state of Washington? L. S. That nearly 2,000,000 Baldwin trees in Kev>r York and New England are estimated to have been killed or so seriously injured by the severe freezes during the v/inter of 1933-34 that their commercial value vras destroyed? L.S. -5- Tliat, accordinr; to a study nade at Cornell University, Mcintosh has usually received a premiuia over other varieties on the New York City mar- ket in accordance with the buying power of employed city \vorkers? Improved buying power together witu reduced uneinployment is likely to increase the premium for Mcintosh. L* S. That mechanical injuries in grading apples are often more serious than those caused by bruising on the tree, by picking, sind by hauling to the packing shed? A four-year study in Ohio emphasized the necessity for making the grading crew "bruise conscious." L. S. That a serious orchard disease which caused land in the far West to be abandoned has been effectively controlled by zinc treatments? This disease has been called "rosette" of pecan and apple trees, "mottle-leaf" of citrus, "yellows" of walnuts and "little leaf" of grapevines and stone fruits. L. S. That it is probably the available metallic zinc, or zinc ion, in the spray mixture containing zinc sulfate which tends to prevent arsenical injury on peaches? L. S. That the Lialling clonal rootstocks are variable in their dwarfing effects on top worked varieties? These vegetatively propagated stocks are known by nu:7ibers. Mailing I, II, III, IV, V, VI and VII usuall;^ produce semi-dwarf trees; Ilallinr X and XIII usually produce standard or vigorous trees but nay have slight dwarfing abilities; IJalling XII, XV, and XVI com- monly produce standard -sized trees; Mailing VIII and IX are very dwarfing rootstocks. L. S. Keep Apples in Refrigerator, Bananas Outside A prominent printing concern recently sent to all its customers a folder showing a grocer pointing to a widely used store hanger and saying, "They sure look like real apples." The hanger conveys this timely v.-ord about fancy apples, "Keep Them Cold, for Crispness." Altiiough the folder is sales promotional in nature, it helps to impress upon consumers the need for keeping apples in the refrigerator. In contrast with this advice about apples, a new radio program carries these suggestions: "Among fresh fruits and vegetables, bananas are one of the fruits that stands high in nutritive value. Don't put bananas in the refrigerator. Let them ripen at comfortable room temperature until their slcins are flecked with brown. That's when they are at their peek of food value and flavor. Just remember that fresh fruits and vegetables are good sources of health giving vitamins and minerals. Serve them often." Strawberries for the Amateur In a recent issue of the Rural New Yorker we find tliese tips for the amateur strawberry grower: 'HVidely spaced rows minixaize labor. We favor marking out v/ith a 5-foot marker, and setting in alternate rows. Intervening rows may be planted to any crop that will be removed by the first of August so that the soil nay be cleaned and leveled. This v;ill allow for developing -6- a 4-foot rovi with a 2-foot path. Nothing sloivs up picking more than having a solid mass of plants with no path. Such wide spacing may not give the greatest returns for the labor involved. Land is plentiful and cheap. Labor is scarce and high. Like all other commercial enterprises, strav/berry growing will be altered by war conditions. During normal times it has been localized to a great extent. Often shipments from berry centers have been made into other areas just as well suited to berry culture. For a time v;e shall see little labor available for picking extensive areas of berries. Transportation will be an increasing problem. Baskets and crates may be hard to procure. All of there factors point toward a decentralization of berry growing. The small grower will have several advantages. Perhaps some labor will be available that would not otherwise be profitably be used. A nearby market is usually available for the small grower. Transportation is at a minimum. He can grow the best table varieties and permit them to attain the fine perfection which comes with a vine ripened berry. Certainly the small grower has all the advantage of meeting emergency conditions." Are Sprayed Apples Injurious to Health? Undoubtedly some consumers eat oranges instead of apples because of fear of arsenic and lead poisoning from sprayed apples. Carefully con- ducted experiments by tlie U. 3. Public Health Service at 'Jjenatchee, Y.ashington failed to show that this fear has any foundation in fact. This study was made to determine to v.-hat extent the eating of sprayed apples affected the healtli of the consumer. VJenatchee was selected as the place to conduct the experiment because the people in that area are exposed to lead and arsenic to a greater extent than those in any other part of the United States. In making this study a total of 1,231 persons were examined, in- cluding men, women and children, representing varying degrees of exposure to lead arsenate. The youngest was a 19 months old girl and the oldest an 86 year old woman. Some ate no apples v/hile others said they ate more than 2,000 a year. Even in a section where excessive amounts of lead arsenate are used so that all apples have to be washed before going to market, 34J3 men and 5 71 v;oraen ate unv.'ashed apples. Various tests were applied to these people, particularly tests which would indicate the general state of health and tlie amount of lead and arsenic eliminated from the body. These tests revealed that blood lead con- centration v/as h'jfh'Jr in orchardists than in non- orchardists but when the orchardist is fr^-.e from s:,:posu:e to lead and arsenic intake, these sub- stances are el:,m:nat-=d rapid.! y so that in a comparatively short time lead and arsenic values in the sody fall t-^ the levels of men who never had an unusual exposure to tlie^e metals, Also, these tests showed that there is no evidence that orchardists \;e:e subject to more ills than non-orchardists, nor had any cases of chronic diseases been caused or influenced by lead arsenate exposure. The results of this experiment indicate that the average consumer has no justifiable reason to sliun apples offered for sale for fear that tliesej apples may contain lead and arsenic deposits which may be hariM^ul to good -7- health, A complete report of this experiment is contained in Public Health Bulletin 2S7, entitled "A St^dy of the Effect of Lead Arsenate Exposure on Orchardists and Consvuners of Sprayed Fruit." This bulletin can be obtained from the Superintendent of Documents, Washington, D. C, at a cost of 40 cents. 0. C. Roberts Locatin- Cause of Pressure Loss in Power Sprayers YJhen a sprayer fails to maintain pressure, a systematic check of the outfit will usually discloce the cause of the trouble. Here are a few su£;- gestions: (1) Is there sufficient liquid in the tank to cover the intake? (2) Is the strainer on the end of the feed line clojjged? (3) Is the strainer in the sediment vrell clogged? (4) Are any valves held open by solid particles-- particularly intake valves? (5) Are any valves stuck? (6) riave the discs worn so that there is too great a discharge from tiie nozzles? (7) Is there an air leak in the feed line? (This may occur v;ith suction feed outfits.) (6) Are any of the plungers leaking? (9) Is the engine operating at the proper speed? (10) Is the pressure regulator out of adjustment? rv p n 0 • C .R. New Grapes A recent issue of the American Fruit Grov.'er calls attention to the Golden Lluscat and Concord Seedless as two new grapes of value. Both of these introductions from the N. Y. (Geneva) Station have fruited in the State College vineyard, but the results v.'ere disappointing. Golden I.iuscat is mucn too late for our short grovvdng season. Concord Seedless is an interesting novelty but hardly worth planting if one v/ants grapes larger than a half grown pea seed. A. P. French Strawberries Resistant to Red Stele Strav^berry growers who have had trouble with Red Stele will find a few varieties which are resistant to that disease. According to Q. G. Boyd, Path- finder, Beauty, Aberdeen and Ilev/ Jersey No. 312 (a new late seedling as yet not named) will grow satisfactorily in the presence of Red Stele. No other varieties are known to be resistant to this disease. Pathfi:ider has been one of our heavier producers and is an attractive berry. Beauty has not done too v/ell in the State College planting but should be tried v/here Red Stele is a problem. N, J. No. 312 looks promising as a late variety but needs further testing. ^,p_P, Fertilizer Supplies By O.P.A. regulation, a top limit on prices which may be charged on sales or deliveries to farmers of mixed fertilizer, superphosphate, or potash has been temporarily frozen for the 60-day period, February 27 to April 27, 1942 at those prices scheduled, listed, or received, in effect during the period February 16 to February 20 of this year. Lov/er prices may be charged. This order does not cover sales of straight nitrogen material. Monthly releases of nitrate of soda stocks are nov; in operation, with 200 tons apportioned to Massachusetts in March tagged half for asparagus and half for miscellaneous use. In response to a request from the Nitrate of Soda -8- Allocation Committee, Director jiunson replied immediately on March 10 as followss "Three thousand, two hundred fifty one tons is the 5-year average sales of urjnixed nitrate of soda reported by the Experiment Station for Massa- chusetts. If nitrate were available, probably consumers would order at least as much tonnage as the 5-year average. Nitrate of soda is used in Massachusetts on orchard lands, grassland, vegetable and tobacco crops. Probably 90 per cent of it is applied before the middle of May. Conse- quently, to be of benefit to Massachusetts farmers, nitrate of soda should be allocated for distribution principally in March and April." Indications are that at least 50/o or more of tlie average tonnage will be released to Massachusetts dependent upon O.P.A., and that equitable dis- tribution is believed most likely to occur tiirough established dealer-customer channels. r, v;. Donaldson Is the Production of Apple Trees Industry or Agriculture? The National Labor Relations Board conducted a hearing in Washington, D. C., March 3, t'^ decide this important question. Present at the hearing were representatives of the National Grange, American Farm Bureau Federation, and the International Apple Association. The case hinges on a proposal made by an N.L.R.B. 3xaminer that a budded or grafted tree is xiot an agricultural plant, that it is not a natural plant, that its production is industry. If this contention is sustained, then, since all our fruit trees are budded or grafted, all engaged in growing these trees for fruit production are not en- gaged in agriculture but in industry, and the agricultural exemption will not apply to these employees. All organizations represented at the hearing asked that the Examiner's report be set aside as incorrect, not in accord with the intent of Congress and not in accord with the common understanding of the word "agriculture*" The history of grafting and budding was covered at the hearing from Theophrastus in 600 B.C., and the planting of grafted trees in England in the reign of Henry VIII was mentioned as evidence of the antiquity and com- mon usage of the grafted tree. Under the proposal of the Examiner many of our farm animals are not in his or her natural state. A mule is not a "natural" animal for usually it cannot reproduce itself, and all employees on farms on which such animals are kept are not employed in agriculture but in industry. The only definition of "agricultural labor" provided by Congress is the one written into the statute at the time of the passat,e of the National Labor Relations Act. This definition is too long to be repeated in Fruit Notes. The complete definition will be supplied if any reader is interested. V;'e scarcely need to mention that this case is involved and far reaching. (Details of this hearing were furnished by H. P. Gilmore of V.'estboro. ) Minutemen Report on Farm Supplies From reports recently summarized, approximately b2^i of the Massachu- setts farmers visited by Minutemen have ordered their repair parts; 51^j, seeds; 5G,J, fertilizers, w'hile only 37fo have ordered spray materials. Sixty percent of those who have scrap iron, have sold it. As a second assignment, Minutemen -9- are asked to make a survey of farm labor n-^eds to determine hov; many extra v/orkers will be needed, when, how long, and for what type of v/ork. A Successful Retailers' School Sixty fruit store ovmers and clerks attended the Retailers' School in Worcester during January and February. Six sessions at weekly intervals v.'ere arranged and sponsored by the Y.'oroester County Extension Service, in cooperation with the Vocational Division of the State Department of Education, State Dept. of Agriculture, and Mass. State College. Those attending viere given instruction in displaying fruits and vegetables, salesmanship, and in methods of handling vAich will lessen the amount of shrinkage. Instructors at the School were G. B. Snyder and V.', H. Thies of M.S.C., Eleanor Bateman of t he State Dept. of Agriculture, and Gladys Goldthorpe Atkins of the V^or- cester County Extension Service. The Rat Menace Robert M. Borg of the Fish & Viildldfe Service has prepared the follow- ing timely suggestions on the control of ratsj "Mankind has no greater, more resourceful, or persistent enemy than the common rat. Rats are found everj'where in Massachusetts working day and night committing depredations. If rats are terribly destructive and dangerous in time of peace, they are doubly so in time of war and emergency. Therefore, in our all-out production for VICTORY v;e cannot afford to let this v/orthless pesiTgo on destroying and contaminating food and vital supplies, spreading disease, causing fires, disrupting communications, and killing domestic livestock. "The rat problem is a general one and concerns every one of us. It can only be solved by our continued and persistent efforts in carrying out measures which are known to produce permanent results. Furthermore, per- manent rat control is the only v/ay to attain the highest degree of health, protection and reduction of economic losses. IIow to meet this problem intelligently and practically is a matter of interest and ; grave concern to us all. Every community can solve its rat problem in a satisfactory manner if v/e, as citizens, do our part by joining in this rat extermina- tion program. "Rats can be permanently excluded by proper construction, repair, and upkeep of all structures and by always keeping the premises in a sanitary condition. Rats require both food and shelter, and they cannot exist where either of these is lacking. Therefore, (1) eliminate all sources of food by protecting it from rats, (2) eliminate all shelter for rats in and out- side of buildings, i.e., places where they hide and breed, (3) eliminate the rats by poisoning, trapping, and gassing, finally (4) eliminate rats permanently by rat-proofing nev;^ and old structures. "The most efficient way to destroy rats is by poisoning them. This involves exposing throughout the rat infested area several kinds of un- poisoned baits (meat, fish, cereal, vegetables, fruit, and others) to find out v;hat bait the rats prefer. Then the preferred bait material should be mixed with the poison according to directions and exposed in the same lo- cation. Only red squill rat baits should be used by the public because -10- this poison has the distinctive advantage of being relatively harmless to human beings and domestic animals. Those baits prepared with other poisons should be exposed only by persons experienced in handling highly toxic ma- terials. ViTierever possible place toxic baits in bait stations av/ay from other forms of life. "Traps are of value primarily in catching the fev/ rats remaining after poisoning operations. Baited traps may be used, but change the bait and location of traps frequently. Unbaited wooden base snap traps are efficient in catching rats if many traps are set so that the rats v;ill trip them by passing over the triggers. Enlarge the standard size trigger witii a three inch square of corrugated cardboard by inserting it between the tvro layers of cardboard. "The fumigation of burrovfs and other harbors is a simple and highly effective method of destroying r at s wherever a sufficient concentration of gas can be obtained readily. Calcium cyanide, exhaust gases from a gasoline motor, carbon bisulfide, sulfur dioxide, acetylene, and chlorine can be used as rat fumigants when properly applied. However, they are all dangerous and must be used with caution." (For additional information on the control of rats, consult your county agricultural agent.) Orchard Experiments at Li. S. C. In the 1941 Report of the Experiment Station mention is made of three tests as follows: Lime and Phosphorus in Planting Trees. Y/e have as yet no evidence that phosphorus is directly beneficial to apple trees on our soils; v^e knovi' that it is readily fixed in the soil and it follows that orchard applications may not pass into the relatively deep-rooted apple trees. An orchard of : 36 Ivlclntosh trees of a single strain on three clonal stocks was planted in the spring of 1941. One third of the trees were treated with 10 pounds dolomitic limestone, one third v/ith 5 pounds triple superphosphate and one ._ third were untreated. The materials were placed in the bottom of the plant- ing holes and well mixed v/ith the soil. As measured by trunk diameter in- crease, the trees treated v/ith lime grew most, those treated with phos- phorus least, while the untreated trees were intermediate. . _ Soil Acidity in the Orchard. Lime was applied to a Sudbury orchard in \vhich aluminum toxicity was suspected, as mentioned in the report of last year. It appears that both grass and trees vrere improved by the treatment. ViTith the increasing use of ivettable sulfur the danger of injuriously high acidity becomes greater. Not only is there danger of aluminum toxicity ■ but nitrification in the soil decreases as the soil acidity increases. Weed Killing. The attempt to get rid of wild cherries » particularly choke cherries, around the peach orchards vms continued. A new weed killer, am- monium sulfamate, v;as tried. It looks very promising. Used at the rate of 0/4 lb. per gallon of v^ater, ''•ne spray was enough to kill small choke I cherries and kill or badly damage black cherries. Chlorate weed killers used at the sajne strength were not so effective on choke cherries and were ineffective on black cherries. J FRUIT NOTES Volume 6 Number 4 April, 1942 Y;. R.

United States Department of Agriculture, and County Extension Services cooperating. Transportation, State and National The efficient use nf our transportation facilities is a national problem. Locally it becomes a trucking problem, nationally a rail problem. lie are fortunate in Massachusetts that we have built local and farm storages for apples in recent years. There will not be a peak demand for trucks to haul apples from farms to terminal storages during the harvest season. Farm trucks can get rubber to haul apples to terminal markets from farm storages as the marketing season progresses. Vfe should begin now to think of the distribution of the 1942 crop of apples. If rail transportation facilities are to be economized, all cross- hauling of traffic must be eliminated. Insofar as it is possible to do so, our applfe growing regions should serve customers nearest to home. There is no reason why New England orchards should not serve New England. The Shen- andoah Valley could serve the Middle East, and Northwestern apples could serve the Middle and Far ITest. This plan is not selfish but comes under the heading of "must." A. H. Lindsey These Changing Times (1) Bulk Shipment of Apples. Can you iraagine shipping Fancy apples except in bushel containers? Bulk shipments are now being considered in the Northwest. In a recent issue of Better Fruit, Howard Fletcher, manager of a Washington growers' organization, says that it is an entirely sound and practical means of transporting apples. He predicts that such a procedure will be both common and economical as v;ell as generally accepted before the war is ended. Besides saving a minimum of 25 cents a box on paper, nails, packing and paper, there is the added advantage of saving storage space and of getting apples into small tovms and thinly populated regions which v;ould not otherwise take a full car. Fletcher does not believe it will be wise to sliip apples in bulk into far eastern markets such as Boston and New York. He does think there is a definite place in the scheme of things for bulk ship- ments into mid-western and prairie areas. There is real danger of a car shortage during the coming season. A temporary shortage developed early in February, for the first time since 1923. It is entirely possible that boxes v\rill not be available for C-Grade fruit, and if this is the case and processing plants are unable to handle all low grade tonnage, bulk shipments might solve the problem. But Fletcher does not rule out the shipping in bulk of Fancy Grade or even Extra Fancy. He points out that if the loss by bruising, stem puncturing and the like, amounted to as much as 10)j, it still would not be as great as the average bruising loss in the bulge pack boxes. He is looking ahead to 1943 when he expects priority on boxes, cars and paper to reach a peak. He does not v/ant anyone to get the idea he favors dumping apples into a car and rolling them off to market. He believes, however, that if 30,000 pounds of apples were loaded carefully into a refrigerator car, straw lined, and carefully handled in loading and unload- ing, they will find a ready sale in many coimnunities. No large scale bulk shipments are likely to be made this season. A portion of the 20,000 bushel crop at the Experimental Station, however, may be marketed in this manner. -3- (2) Law Kicks Out the Cull. Quoting from a recent bulletin re- leased by the National Apple Instit'ute, "No more use of the poorest apples in making any product shipped interstate for human consumption. That is the v/ord this week from the Food and Drug Administration, and they mean business. The rotten, worray or otherwise unclean apples must be entirely discarded or find some other use. Vinegar, Juice, or am'thing else meant for food use must be made from fruit that will not vi'^late the Food and Drug Law. Viola- tions during the coming season will be subject to seizure, injunction, and court action. But the processers we have contacted say they welcome it as a long needed step forward. In some sections, at least, this v/ill mean a notable change. If our impression is correct, there will be few tears shed by growers. Fortunately, product prices are advancing and a small rise in the selling price can mean a considerable difference in v/hat can be paid the grower for acceptable fruit." The following quotation from the manager of a large New England apple by-products plant offers a suggestion along the same line, "\?e hope that every- where you go you will impress upon the fruit growers that a better grade of cider apples will be demanded by all the cider mills this fall so that we may conform to the regulations of the Food and Drug Department of the federal government." In the long run, this cleanup of the cider business maj' be nne of the best things which could possibly happen in the apple industry. (3) Restrictions in Use of P.otenone. Quoting from the Federal Regis- ter, "The fulfillment of requirements for defense of the United States has created a shortage in the supply of rotenone for defense, for private account, and for export. Except as specifically authorized by the Director of Industry Operations, no person shall hereafter use rotenone or any product containing rotenone except for one or more of the following purposes: (a) Use by the Army or the Nav^j- as a delousing agent, or the manufacture of any prepar- ation for such use by the Army or the Navy. (b) Use in the protection of food crops other than cotton, tobacco, cranberries, eggplant, cucurbixs, onions, peppers, and sweet corn, or the manufacture of any preparation for such use." This order, effective April 13, gives the Army and Navy priority on rotenone supplies. It forbids the use of rotenone on the above mentioned vegetables, except that all rotenone and rotenone products processed prior to April 13 may be used without regard to the new order. Presumably tlie manufacturer or processor of rotenone will affix a label to his product mixed and packaged subsequent to April 13. It should be noticed that as yet there are no re- strictions in the use of rotenone on such vegetables as cabbage, peas, cauli- flower, beans, broccoli, radishes, tomatoes, asparagus and potatoes. (4) Orchard Keating. \'ie venture the opinion that no rubber tires will be burned this spring to protect Massachusetts orchards against frost damage . A Note on Spray Residues A recent bulletin from the National Apple Institute contains a mes- sage to fruit growers from the Food and Drug Administration as follov;ss "Advise the growers that, as far as we are concerned, their chief vi^orry vrill be to meet the present tolerances on spray residue. \ie are going to enforce them." -4- The present tolerances are .05 grains per lb. for lead and .025 grains per lb. for arsenic. Massachusetts growers who follov/ the reco:nmenda- tions on the official Spray Chart for Apples, especially with respect to the 5rd and 4th Cover applications, should have no difficulty meeting the require- ments of the present tolerance. 0. C. Roberts Mulching Proves Effective in Michigan More good results from mulching. A recent bulletin from Michigan reports results from a twenty-year-old orchard of five varieties. One-half nf the area was managed on the cultivation-cover crop system. The other half was seeded to clover, which came into bluegrass after four or five years. Straw, daiiiaged hay or weeds was added to the cut grass grovdng among the trees at the rate of about two tons per acre annually. Annual applications of ni- trogenous fertilizer were made in equal amounts to the trees in both areas. Soil moisture v,ras considerably higher under the mulch. Depth of freezing was less and the mulch material prevented erosion. The trees in cultivation grew faster and produced better through the first 10 years. Later, the mulched trees bore heavier crops of better apples. The Michigan investigators recom- mend cultivation for young orchards, with due regard to preventing soil ero- sion, followed by sod with added mulch at the age of perhaps 10 to 15 years. The maintenance costs of the two systems did not differ widely. J.K.Shaw Variation in Yield of Cional Stocks A new stock bed for growing clonal stocks yielded its first crop of rooted stocks this spring. Calculated on an acre basis, the yields of the more comraon Mailing stocks varied from about 7,000 Mailing II to 22,000 Mailing XVI. Others were Mailing I, 11,000; IV, 16,000; IX, 6,000. Doubtless one reason for these rather vride differences is due to soil and season. But some stocks send up shoots more freely than others and there are differences in the root forming ability of the shoots. Yields are expected to increase as the bed gets older. Dwarfing stocks sell for about (l^SO per thousand compared with $15 for seedling stocks. A yield of 15,000 dvmrfing stocks per acre would give a gross return of $450 per acre. Here is another way to get rich (?). J.K.Shaw Deep Placement of Fertilizers In studies of sub-surface placement of commercial fertilizers and man- ure, a Mcintosh orchard at Geneva, N. Y. gave no better response over a 3-2''ear period to any method of deep placement than to the usual surface broadcast ap- plication* The conclusion is drawn that until more is knovm concerning the problem the greater expense of placing fertilizers in the root zone of trees is unjustified. In some of the tests, the fertilizer was placed in equal amounts in each of 20 holes made v;ith an iron bar some 20 inches deep in a circle near the ends of the outer branches. In others, four large post holes were dug to a depth of 24 inches, equidistant around the tree, near the ends of the outer branches. The fertilizer v/as then mixed v/ith the soil from each hole so that the mixture rested from 12-24 inches below the surface. (This work is reported in Geneva, N, Y., Bulletin ^^691. ) Storage of Apples in Modified Atmosphere The objective in modified atmosphere storage for apples is simply better preservation. It is generally agreed that many New England apples, and ■5- Mclntosh in particular, nay lose much of their faiaous high quality in pro- longed cold storage. In raodified atmosphere storage at 40° F. , the life processes (ripening) nf apples are slowed dovrn more effectively than in com- mon 32° F. cold storage. Theoretically, this should result in apples keeping longer in better condition. This is the purpose of developing the modified method of storage. Briefly, the slowing down of ripening processes in modified atmosphere storage is the result of maintaining a low oxygen concentration (around 2%, coi.ipared vdth 21% in air) and a relativeJy h:gh carbon dioxide level (5 to lO^o compared with .03% in air). These factrjrs more than counteract the effect of the higher storage temperature, 40° F. This nigher temperature is helpful in decreasing core breakdown and in maintaining b&tter quality in Kclntosh. The modified storage room must bs practically ''gas-tight." Otherwise, as the apples uti]ize the oxygen in the air, leakage will prevent the actual decrease in oxygen percentage which is required. The storage room at Li.S.C. was not sufficiently tight in 194u-41 and during the ?tart of the 1941-42 season. Very ynall leaks prevented succsosful operation. HOvvever, since December, ]941,, this storage has perforned satisf .-ictcrily. Considering the degree of maturity of tiie apples when the fcragH began to funotion properly, they came out in rather good condition the '.atter p»rb of March, LIcIntosh v.-ere over-mature, of course, ar^d a little flat in taste, bat '-therwise satis- factory. Coftiand scalded, as v.'as expected. Golden Dej.icious were in excel- lent condition with practically no shrivelling. It seems that this type of storage nay be useful for extended holding of Golden Delicious j as for L'clntosh. A condensation of this subject from the Annual Report of the Llass. Agrl . Exp. Sta., 1S41, follows: Experiments with 40- quart milk cans as gas- tight containers gave some interesting results. Special atmospheres vrjre maintained by remo-'/al of carbon dioxide generated by the fruit, by flushing with pure nitrogen at intervals, and by controlling ventilav,ion- Storage tem- perature wab 40'' F. In the can in which the oxygen was aiiov.ed to remain be- low 1% and the carbon dioxide was rather high, the apples developed a slight alcoholic taste which was evidence of anaerobic resp;'.:-ation. The best Llclntosh came from a can opened May 13, v;hich had been flushed with nitrcgen. These apples v^-jre decidedly bettor than checks kept at 52° to 33'-' F. in the usual way. The oxygen had been maintained in the range of 2 to 6% and the carbon dioxide between 2 and 12%. In this, as in all of our storage tests, well ma- tured, v.'ell colored Mcintosh gave the best results. V.'e have learned through experience that a successful modified atmos- phere storage must be just about "gas-tight." This is perhaps the most im- portant factor to be considered by growers who may at some time contemplate converting present rooms or constructing new ones. There is still much to be learned about modified a tmosphere storage. However, several such storages are being operated, and rather successfully, in Ijev; York State. It is entirely possible that modified atmisphero storage, especially for Llclntosh, and pos- sibly Delicious and Golden Delicious, may displace, in some degree, present day conventional cold storage met?iods. L. Southwick Nicotine at N i ght S. IT. Harmon of the New York Agricultural Experiment Station at Geneva reports in a recent publication a very interesting point to consider in night -6- spraying, ''It often affords dead caln oonditions which permit spraj'-s contain- ing nicotine to produce a fumigation effect that is seldom possible in daylight. The taxie fumes hang in the trees for long periods seemingly killing all active insect life. After such a treatment it is usually a week or 10 days at least before in§ect life becomes re-established," L, Southwick Keep 'Em Growing About the v:orst thing which can happen to a newly set fruit tree is to stand still or make practically no growth during the first season. If this happens, it means not only a loss of time, but when the tree is finally in- duced to grov;, it is more than likely tn sprout from the trunk instead of the branches. Let's make sure this does not happen with fruit trees set this spring. Whatever is needed to insure good grovrth should be provided. Early planting, watering, mulching, and if needed, a little nitrogenous fertilizer or manure, provide good insurance that the tree will not only live during the summer but that it will make a vigorous grovrth. It is easy to develop a good framework in a tree which makes good grov.i;h from the start. But if it loafs along for a year or two, shaping is difficult and the stage of profitable bear- ing is postponed. Direct Sales of Fancy Fruit A few days ago a representative of three hotels in Boston expressed an interest in supplies of five fruits, — strav/berries, raspberries, blueberries, peaches, and grapes during the coming season. Instead of picking up these fruits on the wholesale market each day, he wants to contact individual growers in Massachusetts v;ho can supply these fruits while each is in its prime. Of the small fruits, the amounts needed var^' from 2 to 7 crates daily. Five to 10 bushels of peaches and about 2 bushels of grapes are daily requirements. Any grovrer interested in this opportunity for direct sales of fancy fruits may obtain further details by dropping a line to the v/riter. D'-' You Know? That about half of the total area of Llass. is suitable for agricul- tural utilization? The percentage of agricultural suitability varies from nearly l/3 in Barnstable County to slightly less than 2/3 in Vforcester County. That of the total state area, nearly 2/3 is under wooded cover? The highest proportion (nearly 3/4) is in Barnstable and Berkshire Counties. The lowest (slightly more than half) is in Essex and Middlesex Counties. That salesmanship means "selling goods that won't come back to cus- tomers that v/ill?" That American consumers pay about $2,000,000,000 a year for fresh fruits and vegetables? O^t of this total, according to E. R. French, marketing director of a large chain store, the farmers who grov/ the fruits and vegetables get only about $700,000,000. That the United States farm price of apples as recorded for Feb. 15 was $1.20 per bushel as compared viith 93/ per bushel on the same date in 1941? V;ith the exception of the latter part of the 1936-37 season, the 1942 farm I ♦ 7- price is higher than at emy time since the 1930-31 season. Thftt the net decrease of apple holdings in the United States during the month of IJarch amounted to about 6,000,000 bushels or 42^0 of the amount on hand March 1? The net decreases during March for the five preceding years were as follows: 1941 - 38?o, 1940 - 40^, 1939 - 40^/., 1938 - 38f», 1937 - 40f.. That American farmers throw away enough used baling wire each year to build three battleships or 3,000 medium sized tanks? Much of the 100,000 tons of bailing wire used each year is allowed to rust away in the scrap heap after being used but once. That more nitrogenous fertiliser is produced by lightning than is produced in all the synthetic nitrogen factories in the world? It is estimated that there are about 2,000,000,000 lightning strokes (about 7 for every square mile of earth), which results in the annual production of 100,000,000 tons of nitric acid. That more thaja three times as large a Tolume of mixed fertiliiers was sold by a large Ilev: England distributor un to April 1, 1942, than was sold during the same period, 1941? The amounts for the two years were approximately 8,000 tons and 2,300 tons, respectively. The 1942 sales of each of the fol- lowing mixed fertilizers of fairly high nitrogen content, namely, 10-5-5, 10-10-10, and 7-7-7, have amounted to more than 2-|- times the 1941 sales. Less than 755? as many tons of nitrogenous fertilizers were sold in New England up to April 1 as in 1941. That American farmers will produce in 1942 enough 10-gallon cans of milk to build 25 pyramids the size of the great pyramid of Egypt? They will also produce enough eggs so that if you broke one every second it would take 1600 years to break them all. Enough peanuts and soy bean oil v/ill be pro- duced to make more than 60 bars of soap as big as the RCA Building. The pro- duction of hogs would make a solid procession, two abreast, clear around the world. Gasoline for Farmers On March 26, S. R. Parker, County Agent Leader, wrote to M. Clifford Townsend, Director of the Office of Agricultural Defense Relations aind on April 15 received the following report. It is apparent from this letter that as far as the orders are concerned, supplies are provided for all farm uses. It may be necessary for a farmer to file vrith his usual source of supply a cer- tification sucii as is included here. "In your letter of Llarch 26, you pointed out that the Massachusetts State USDA War Board is concerned about the proposed rationing of gasoline and is afraid that farmers might not be able to get the supply they require for their trac"t^rs and engine pumps under a rationing system. You may be sure that this office will do whatever it can to protect the interests of farmers in this matter.

Xle do not consider it advisable to make a general reconunendation to include creosote in all sprays for the following reasons i 1. Under some c<)nditions foliage injury has resulted from an application of creosote from the addition of creosote in the leacl arsenate spray mixture. We do not consider that sufficient work has been done to es- tablish the conditions under which creosote can be applied with safety. 2. The duration of the repellency of creosote has not been determined. Therefore, it cannot be stated whether one or several creosote sprays would be necessary to repel the bees. 3. Creosote is a mixture of variable composition. It is considered unwise to make a general recommendation based on a material which may vary con- siderably in its chemical make^-\ap. At the present time some work is in progress which should give us additional information as r egards the safety of creosote to foliage. T/Te are also plsmning some experimental work to try to determine the efficiency of creosote as a repellent. In the meantime we consider it inadvisable to make a recommendation to include creosote indiscriminately in spray mixtures. F. R. Shaw One YJay to Grow Peaches H. N. Click of the Department of Psychology reports a full bloom on one of the branches of the peach trees in his yard. All of the other fruit buds" failed to survive the low temperatures of late winter. This particular branch hangs over the roof of a henhouse which was apparently covered with snov: when the coldest weather occurred. This offers an interesting illustration of profiti in a diversified (fruit-poultry) enterprise. FRUIT ITOTES Voliuiie G Number 5 May, 194E Vf. H.

However, there are seldom distinct generations because of overlapping of br'^ods, Regardless of the number of generations, tlie mites are usually most abundant and destructive in late July and August. This pest is frequently held in check by natural enemies. However, these are predators rather than internal parasites such as are liberated to control the oriental fruit moth.

United States Department of Agriculture, and County Extension Services cooperating. -2- abundant predatory enemies are the lady beetle, Stethorus punctum, and the predatory mite Seius pomi, although thrips and a predaceous bug are also active enemies. ilormal winter eggs are bright red and summer eggs are pale straw color. Any white appearing or dull light colored "eggs" are usually the shells from hatched mites or eggs from which the contents have been sucked by predatory enemies. Heavily infested trees are seldom badly infested the following year because the natural enemies are very active late in the season and the mites usually migrate from badly bronzed foliage which lacks suitable food. An adjacent block of trees is more likely to be infested the second year. Red mites are strongly influenced by weather and although an abundance' of winter eggs will provide a source for an early infestation, unfavorable weather or a plentiful supply of natural enemies may prevent noticeable damage to the foliage, before midsummer. On the other hand, mites spread by the wind or by birds may develop by late summer into a destructive infestation on trees which bore relatively few winter eggs. Hot dry weather is favorable to rapid multiplication of red mite, and rain and cool weather delay the increase of this pest. Heavy rain storms such as thunder showers frequently knock thou- sands of mites from the leaves and may prevent an infestation from becoming serious. Lime sulfur (liquid) 1-50 kills red mite and when this material was generally used in pre-blossom sprays many potential infestations were pre- vented. Wettable sulfur or sulfur dust does not kill red mite effectively; in fact, it kills the natural enemies of the red mite mors easily than it does the pest. The available summer sprays are not very satisfactory. Ro- tenone sprays and dusts are too expensive; soap is d\fr?cult to apply, and nicotine is not effective. Last year, modified forms vf DN sprays and dusts appeared very promising and it is hoped that they will supply the answer to this troublesome problem. On the basis of our present knov^rledge, hov;ever, the wise fruit grower will apply a dormant or delayed dormant spray on trees Vi'hich bear a heavy population of v;inter eggs of the red mite and spray most of his orchard in this way about once in each 3 years. To date, the summer troatmcnts should be considered as emergency sprays which should be used only to prevent excessive bronzing of the foliage. W. D. Vifhitcomb Codling Moth , - Apple Enemy No. 1 The codling moth is the most serious insect pest of apples in the country. It is claimed tliat this insect causes a loss of 12 to 15 million dollars annually to the commercial apple crop. In addition, it is estimated that we pay 3 to 5 million dollars a year to spray the orchards of the country^ ■to check this pest. The apple is the favored host and all varieties are at- tacked, but pears, peaches, and quinces may be infested. The codling moth passes the winter as a full-grown larva within a tightly woven cocoon. These cocoons may be fnund under rough bark, around old pruning scars, and other crevices on the trees. They are often found in old boxes in or around packing houses and storage sheds. Prop poles, piled I ■3- in or near the orchard, often harbor numerous larvae and serve as centers of infostation. Coarse trash, such as broken boxes, baskets, basket pads/ broken branches and prunings which may be present under the trees, should be removed and destroyed, because they provide shelter for the larvae. Pupation of the overwintering larvae begins about the time the fruit buds show pink. Moths usually appear v.'hen apples are in full bloom, and emer- gence may continue for five to six vreeks. Larvae which over-winter in packing liousfjs and storage sheds tend to pupate later than those in the orchard. This I'^.ssons th'^; value of a spray schedule based on orchard conditions and amphai^izes the need of screening of packing houses and treatment of old containers. Stor- age and packing houses should be screened and kept tightly closed until after moth emergence. The moths usually remain quiet during the day and bectjme active at dusk. Four or five days after emergence the females begin to lay eggs on leaves and fruit. If the v>reather is cold or storiaj'', egg laying is delayed. The eggs hatch in about 6 or 7 days, and the young larvae promptly crawl to the fruit. Llany of the early larvae enter the fruit through the calyx end. The larvae that appear later in the season tend to enter through the side, usually where tviro apples touch, Vi/here a leaf rests on an apple, or at the mar- gins of old curculio scars or other areas where the surface of t!ie fruit has been russeted or roughened. The larvae require about 3 weeks to mature, after which they emerge from the fruit and coimnence to spin their cocoons. Most of the larvae v;hich mature before mid-iJuly transform at once to pupae and form a second generation. Later emerging larvae crawl to a sheltered spot and spin cocoons in which they pass the winter. There is normally one complete, and a partial second genera- tion of the codling moth in Massachusetts. In seasons when weather conditions favor an early maturity of the larvae, the second generation is greater than normal, resulting in more late season damage to the fruit. Thorough spraying with lead arsenate is the standard method of control. Several applications are recommended as specified in the Massachusetts Apple Spray Chart. Dust schedules have not proved so effective as spraj/-s in codling moth control. Recent tests v.dth materials other than arsenicals (fixed nico- tines, etc.) have shown promise, particularly in late summer applications, when they may be applied to give protection against second brood larvae without in- curring the risk of excessive spray residue on the fruit at harvest time. Scraping loose bark from the tr-ves in late v;inter or early spring re- duces the population of oven'.'intering larvae, Wiere possible, such scrapingc should be collected and promptly destroyed. Chemically treated bands j placed around the trunls of the trees, will collect large numbers of larvae. Larvae entering these bands will be killed and thus, by the disposal of early emerging larvae, the danger of a heavy second brood is reduced. In addition, the dec- truction of late emerging larvae will tend to reduce the danger of heavj^ infes- tation the following season. Bands diould be in place on the trees by at least the middle of June and should remain until th-- fruit is harvested and all drops have been col- -4- lected and removed from the orchard. Treated bands should be removed, however, before winter. In recent tests, a donnant application of an oil-pyrethrum mixture has given good results in penetrating the overwintering cocoons and killing the larvae. Prop poles may also be sprayed with this combination. This treatment is still more or less experimental but it requires less time and labor in scraping the trees and is one of the most promising of the re- cent developments. A. I. Bourne Time Required for Apple Scab Infections How long must apple trees remain wet before scab infection takes place? It depends upon the temperature. Only half as much time is required at GO*^ as at 40°. And a light infection requires only half as much time as a heavy infection. 0. C.

V»'e should keep apples at a level where everyone can buy them and use them regularly. Abnormally high apple prices would either accompany, or be preceded by, large increases in the cost of things bought by the fruit grower. All things considered he will be better off if apple pricos remain in line with" the prices of other products. Trans- portation difficulties and smaller imports of other fruits, such as bananas, emphasize the mutual advantage in supplying nearby markets. An increase in net income will be permanently advantageous for the fruit grower, if he (I) pays off debts with his cheaper dollars, and (2) if he avoids unwarranted expansion of his productive capacity at inflated costs. This does not mean that the fruit grower should retrench or discontinue, for the duration, the planting of tfees. On the contrary, this ma,y be just the time to bring the fruit plantation up to a more economic size. If .the present sprayer is capable of handling more trees, and a suitable area is available adjacent to the young orchard, an extension of the planting would seem an -4- economical procedure, if it can be accomplished without going in debt. When the war is over, a thrifty, young orchard may look even better to the owner than it would now. Bui this is not the time to buy a new fruit farm on borrow- ed capital. The present plantation should be consolidated and improved. It should be made to produce more high grade fruit per acre through better manage- ment. All equipment should be kept in good running order. If possible it should be repaired and overhauled instead of buying new equipment. Seven steps have been proposed by our federal authorities to prevent inflation and to halt the rising costs of living. These include: (1) tax heavily, (2) place price ceilings on goods and rent, (3) stabilize wages, (4) stabilize prices of farm products, (5) encourage increased purchases of war bonds, (6) ration all essential commodities that are scarce, (7) discourage installment buying and encourage the paying off of debts. As we face an extremely critical time in our history, the fruit grower can contribute his part to the nation wide price control program by (1) paying off all debts possible, (2) putting surplus money into war bonds, (3) making essential improvements without expanding in a way that requires essential war materials and skilled labor, (4) spending no money for things which are not essential for the fruit enterprise or for family living, (5) cooperating whole- heartedly in the nation wide program to control inflation through price ceil- ings, rationing, and other means which may be devised for winning the peace as well as the war. Conserving Poultry Manure During this period of nitrogen shortage every farmer should be inter- ested in the conservation and more efficient use of poultry manure. Reports of dumping this valuable material over a bank on one largo poultry farm have re- cently been received. A nearby farmer might have it for the hauling. This is an example of inexcusable v/aste. R. W. Donaldson, Extension Agronomist, offers these suggestions for storing poultry manure where it is not possible to distribute it immediately: "If storage is necessary, a miniuium area of surface should be exposed and com- paction secured by added water to reduce aeration. Insulation of surfaces with absorbent loam and superphosphate to catch escaping nitrogen are import- ant. Storing in a pile as deep as possible (5 feet or more), v;ith perpendicu- lar walls and concave top to catch and retain moisture is advised. A layer of earth (an inch or so) and 300 to 500 pounds of superphosphate scattered over each cord will do much to catch and retain escaping nitrogen. A deep pile benefits from absorbed rainfall, and vdll not leach. During dry spells, wotting down of piles may he advisable." If a pile of poultry manure is allowed to dry out nitrogen is lost, as evidenced by the aimnonia odor. If the pile is kept wet and compact, par- ticularly if loam and superphosphate are added, the nitrogen is conserved. Fruit growers are missing a real opportunity if they fail to obtain poultry manure wherever it can be had in quantity within easy hauling distance. Most poultrymen vmnt the manure removed regularly. And if it is hauled at a time when it may not be applied with utmost safety in the orchard (July to mid- winter) it should be properly stored, or it may be used outside the orchard for grovfing mulch material. Any sod orchard with scanty growth of grass or weeds will benefit from a broadcast application of poultry manure. This is also an excellent fertilizer for growing young trees but must be used in moderation in a bearing orchard. Green, lat-; maturing fruit may be an in- dication that poultry manure should be applied elsev;here. Facts and Opinions About Bees In a recent letter from John Rice of Marlboro, two questions are asked, (1) concerning the effect of bee stings on arthritis and (2) concerning the number of blossoms visited by bees during rainy and sunny weather. On the lat- ter question, one individual (not a fruit grower) had expressed this opinion; That a bee will pick up enough pollen to carry a load by visiting 25 blossoms; that when there has been a shower and the pollen has been vmshed away a bee will have to go to about 100 blossoms to get the same load they would probably get on a clear, v/arm, sunny day in visiting 25 blossoms. And as it rained all day Thursday the bees would have to visit after Thursday about 250 blossoms or ten times as many as they would during vmrm, sunny weather. F. R. Shaw of the Dept . of Entomology, offers the following coiTiments on these points: (1) "As regards the treatment of arthritis by bee venom - this has been demonstrated of value both in this country and abroad for many years. As early as 1879, Philip Terc, an Austrian physician, expressed the opinion that 'almost all true arthritis and rheumatism can be radically and permanently cured with bee stings except those cases of many years' standing where ossification has taken placa.' In this country Dr. Beck of New York City has treated many cases of rheumatism and arthritis with good results. However, no one should attempt to use bes venom as a treatment except under the direct supervision of a doctor." (2) "As regards the theory concerning the value of rain as an agent for improving the set of fruit, I am inclined to doubt its importance as far as its necessitating bees to visit more flow- ers to get a load of pollen. Bees work from 25-75 apple blossoms to get a load of pollen. During the period when it was raining, the bees were confined to the hive. This would certainly cause a poorer set than if the bees were working. Following a rain, the blossoms that were open during this period T;ould not likely be as attractive as blossoms that opened following the rain since the amount of sugar present in the nectar would be lessened by dilution with rain water. Then if the statement made concerning the amount of pollen present v;ere true, which I doubt, the old blossoms v;ould have little to offer to attract the boes." Summer Management of Beos in War Time Follov/ing is a suninary of a statement prepared by B . N. Gates and F. R. Shaw, authorities in beekeeping in Massachusotts* Due to the unsettled conditions concerning the possibility of obtaining sugar for feeding bees this fall or next spring, good management of bees during the summer and proper preparation of colonies for wintering are essential. The season thus far has been conducive to svrarming. Most colonies were strong early in the spring. This, together with the fact that v/e had on early spring, resulted in exceptionally strong colonies. Following apple bloom vie had a period of rainy weather which caused crowding in the hives and the bees built swarm colls in great numbers. Swarming has been prevalent and beekeepers must be on the alert to prevent both further swarming and after- swarming if they expect -6- a maximum crop of honey. For a complete discussion of the problem of swarming and its controj, see U.S.D.A. Farmers' Bulletin 1198. During this summer, weak colonies should be united to other weak colonies or to strong ones. This will eliminate in part the necessity for fall feeding and will also take full advantage of the available force of bees. It is the opinion of both of the writers that beekeepers must recognize tha importance of strong colonies of young bees provided with ample »tores of honey and pollen in order to accomplish successful wintering. G©od manage- ment throughout the honey flow is absolutely essential in order to have colo- nies strong in bees and well provided with stores. Old queens should be re- placed by August 1. Small colonies should be united or else killed by the first of October and the hive and etjuipment be placed in safe storage until the following spring. The situation is briefly this: (l) The prospects for obtaining sugar for fall feeding or for spring feeding in 1943 are very unsettled. (2) Good management throughout the active season is especially important since swarming is prevalent and since we must obtain as large a crop of honey as possible, (3) Do not bother with weak colonies. Unite them to other colonies or destroy them . Do not foed colonies sugar syrup unless it is an absolute necessity . Timely Tips for Fruit Growers (by H.A. Rollins, U. of Conn., Storrs, Conn.) Fruit Thinning Important in 1942 . By thinning fruit on heavily loaded peach and apple trees, fruit growers will definitely reduce the harvest labor problem. With inexperienced harvest help last year, too many cull apples went into storage. Here is an opportunity to remove the culls in early summer and allow the clean apples to improve in size and color. Although it may be dif- ficult to obtain labor for thinning, it certainly is worth the trouble and effort to thin both apples and peaches in view of the reduced labor problem at harvest. For best results in size of fruit and improvement in color, thin early. With proper supervision, high school boys, high school girls and women can be used for fruit thinning. It is too early to make any procJSctions regarding crop prospects but at present there appears to be a fair-to-good fruit set. Mcintosh apples appear to be heavy enough and in some orchards the Baldwin set is much too heavy. If the June drop does not greatly reduce the load of fruit on some trees, you certainly should plan to thin fruit on these trees as early as possible. Ladino Clover Frunishes Nitrogen. With the prospect that there will be less nitrogen fertilizer available next year, there is even more need for Connecticut fruit growers to plant Ladino clover as an orchard cover crop where it is possible to do so. Mr. Henry Fetors of Hamden, after seeding Ladino clover four years ago, has omitted nitrogen on mature Mcintosh apple trees for the past three years with very satisfactory crops of apples and excellent tree growth. Other growers have found that they can definitely reduce their nitrogen application if they have a good stand of Ladino clover as a cover crop. It is not too late to consider seeding for this year. For more complete information on using Ladino clover as an orchard cover crop, see your county agricultural agent. Apple Boxes for the 1942 Crop. If you have not already obtained apple boxes, either used or nev;, for" the 1942 apple crop, you should not delay order- -7- ing if you expect to have containers for apples this fall. Although there was considerable hurricane lumber in the New England area, this is being used at the rate of more tlian a million board feet a week for boxes, mostly for war purposes. The situation regarding nails for apple boxes appears to be consider- ably brighter as a result of a recent conference in V/ashington. There would be considerable wastage if packages were not available for perishable crops such as apples. Nails for apple boxes now have a priority rating of A-l-C, which is practically the same as for most military materials and considerably higher than the A-7 rating previously given. Fruit growers should be able to obtain box nails from their regular dealers. The dealer in turn, can make use of the A-l-C priority rating.

Costs--largely represented in gasoline, oil, emd tires — are based on actual records of a fleet of more than 325 state-owned vehicles, supplied and checked by automotive experts. There's only one thing wrong with the table: It doesn't mention that excess speed is the greatest single cause of automotive deaths and injuries. From now until the war ends — 40 or under i Seen and Heard in the Field Peach Borers. Last October 30 peach trees ranging in age from 3 to 9 years v;ere treated with ethylene dichloride in the Willkie orchard in Lake- ville. These trees, virere badly infested with borers at that time. Care v/as taken in diluting the material and in pouring it on the soil immediately ad- jacent to the trunk, because of reports of severe injury from this material in other states* An inspection of the trees about three weeks ago revealed a complete kill of borers and so far as we could observe no sign of injury to the trees. "Ringing." In two recent twilight meetings (Segreganset and Hathorne) a grower has reported success in bringing about fruit bud formation by the practice of "ringing" or girdling. In each case we had demonstrated this method by cutting completely through the bark of certain apple branches in May, 1941. The rest of the tree was left as a check. According to the growers' reports those branches bloomed heavily this spring while the other branches on the trees showed only an occasional blossom. Cross Pollination. In the Saari orchard in Ashby there is a striking illustration of the effect of suitable pollen on the set of Mcintosh. A sin- gle branch was grafted to Astrachan or other good pollenizer on certain trees about three years ago. These grafted branches bloomed well this spring. Mcintosh branches in close proximity to the graft show an exceptionally heavy set of fruit while similar trees not grafted show only a moderate set. Trees which are farthest from a pollenizing variety show a relatively light set. A Big Blueberry. A blueberry was found on June 16 which by actual measurement had a diameter amounting to 5/8 of an inch. This berry was already shov;ing signs of coloring. Another bit of evidence that the season is ahead of normal. 5) 1 -9- Rosy Aphis. An unusually haavy infestation of rosy aphis observed at a recent orchard meeting raised the question, what can we do about it? One grower reported a similar condition three years ago and stated that he had completely cleaned it up since that time by spraying at the dormant stage with one of the DN materials. At this season a thorough application of nico- tine plus two pounds of soap flakes will help to prevent some of the aphids from migrating to the fruit clusters. At the same time the grower should resolve to apply DN next spring. Apple Curculio. At a recent twilight meeting in Granville we de- cided to capture a curculio beetle for certain members of the group, not acquainted with that pest, to examine. Thinking that a heavily loaded plum tre=; v;ould yield a specimen of plum curculio, we jarred such a tree only to capture one lone beetle and an apple curculio at that. Roadside Stands. One enterprising fruit grower is considering the establishment of a fruit store in a filling station which is not being used at the present time. Located as it is at the outskirts of a city, such a move will help to bring products of the farm within reach of pedestrians. If tires and gasoline are not available for driving to a roadside stand in the country why not bring the stand within walking distance of the consumer? Newly Planted Trees. There seems to be a big difference in the amount of growth made thus far by newly set apple trees. Some have grown a foot or more; others are barely holding their own. A reminder at this season that fruit trees should be made to grow vigorously from the start, may be in order. If certain trees are lagging, it is not too late to give them an application of nitrate of soda or to mulch heavily. A thorough job of eliminating competing grass and weeds will help, but a replenishment of the nitrates washed out of the soil by recent ra.ins may help even more.

Gennnell of the Agricultural Insecti- cide and Fungicide Association.) The real values which lie behind many of the agricultural chemicals we commonly use are often lost sight of, because of the present day necessity to get the job done quickly in order to take advantage of particularly fine weather or to make the best possible use of the farm labor available to us. Vfiiether it be a spraying or dusting operation, little thought is given to the time spent in research or to the eflort that has been put into the production of many common corrimercial chemicals to insure the ultimate con- suTiier the highest value at the lowest cost consistent with high quality. Many such products used on the farm have thus come to be taken for granted; and little serious consideration given to their past history or to their value in terms of better and more abundant crops. The case of Lead Arsenate aptly il- lustrates this. Up until our recent emergency. Lead Arsenate, of which 59,000,000 to 60,000,000 pounds is used annually in this country, has been very easy to obtain and has, therefore, been used in our spraying or dusting programs without much regard for the raw materials -which go to make it up, or for the amount that was used in our pest control programs. Now that agri- culture is in the position of competing with the war industries for the Lead and Arsenic which go into the making of Lead Arsenate, some understanding of the manufacturing problems which lie behind this common spray chemical may enable us to properly evaluate it. Hist.-^ry. F. C, Moulton, of the Massachusetts Gypsy Moth Committee is creditlTd wxth" the discovery in 1892 of the insecticidal properties of Lead Arsenate and late in 1893 its use as an insecticide was recommended. Although the early ro.atsrial resembled in many ways the chemical as we know it today, it differed in many important respects. The early methods of prep- aration vrere crude and expensive, the product variable, and as then sold contained 40-50^ water. Although the same two forms ; acid and basic Lead Arsenate, were known then as now, the former, the acid or standard type, has far surpassed the basic type in importance to the fruit grower. In the early procedure for preparing acid Lead Arsenate (PbHAs04) solutions of lead acetate or lead nitrate were precipitated by sodium arsenate (Na2HAs04) and the product aold as a paste with a high water content. However, with the granting of over 3D patents relating to Lead Arsenate production, the! methods of manufacture have improved and today the dry powdered product now offered for sale contains almost pure lead arsenate. That such a product can be sold at its usual low figure is a monumental tribute to the early research workers and to the agriculturists who cooperated with them in testing out the product on various food crops.

This is almost exactly the same as in 1941. The prospects in New England and New Yorl: are about 20'/o better than last year. The Appalachian region reports prospects very close to that of last year with the crop running heavier to fall varieties. In the iJiddle lYest there are indications of fewer summer apples and more of winter varieties. The total crop in that area will probably be lOJo less than in 1941. In the Far \7est, sonevrhat fewei' Delicious are expected but the Vi'inesap trees promise a larger crop than in 1941. The total in that area should be about the sa:Ae as last year.

There are prospects that the Mcintosh crop vdll be somewhat larger than in 1941. At a meeting July 2 in the Fred Middleton Orchard in Hudson, 40 com- mercial growers gave the following estimate of this season's crop in comparison with 1941; {The total of all varieties in 1941 was 175,180 bushels; 1942, 210,595 bushels, an increase of about 20^ over last year. The figures for the three most important varieties, Mcintosh, Baldwin and Delicious were, re- spectively: 1941 - 113,780; 23,490; and 9,285. 1942 - 125,620; 53,490; and 10,460. At a similar meeting in Connecticut, 35 growers representing l/3 of the commercial apple crop reported a total of 395,000 bushels last year and 524,000 this year, an increase of about 32^. The figures for Mcintosh and Baldwin were, respectively: 1941 - 186,000 and 104,000. 1942 - 234,000 and 169,000. The peach crop in New England this season is expected to total 200,000 bushels compared with 209,000 bushels last season. The 10 year average is 287,000 bushels. The outlook for pears in New England is about the same as last year - 153,000 bushels. The 10 year average is 165,000 bushels. GRASS ROOTS A^ID TREE ROOTS In a recent Michigan study the rooting habits of 9 species of grasses were observed. The grasses include Sheep Fescue, Kentucky Bluegrass, Chewings Fescue, Timothy, Redtop, Canada Bluegrass, Reed Canary Grass, Witch or Quack Grass, and Smooth Brome Grass. The last three named grasses showed a larger proportion of their root systems .in the lower half of the containers than the others. Vfitch grass or quack grass actually showed as many fibrous roots at tl^ 42 to 48-inch level as at the 24 to 30- inch level. The investi- gator, N. L. Partridge, says, "The larger the development of roots in the lower portion of the container, the greater the probable amounts of water which the grass might be expected to remove from the deeper portions of the soil." These observations throw some light on the behavior of young fruit trees which must compete with a deep rooted grass. If the soil is already oc- cupied by . grass roots to a depth of three or four feet, the tree has a diffi- cult time developing its roots because the soil may already be depleted of needed moisture as well as nitrogen and other mineral elements. The scanty growth of young trees under such conditions may reflect that competition. It takes a good soil to support both grass and tree. A young tree ^ould be either cultivated or mulched in such way that competing vegetation is smothered. The failure of many young orchards may be traced to the fact that the trees were compelled to fight it out with a stand of grass already established. Mid- summer is a good time to ch'3ck up on the growth made by young trees and to remedy the situation by cultivation, additional mulch or a few handful s of nitrate of soda. This latter item is important if heavy rains have leached out the nitrates so essential in getting the tree off to a good start.

Gemiaell of the Agricultural Insecticide and Fungicide Association. -- Continued from the June issue.) Method of Production. Today, almost v.dthout exception, commercial Lead Arsenate is ms^de by adding arsenic acid to litharge (PbO), a reddish yellow lead compound made by roasting metallic lead. In order to insure complete reaction, the mixture is kept constantly stirred and the resultant slurry of Lead Arsenate and water is carefully checked by control chemists who analyze it in this stage so that by careful acid addition and close con- trol of the temperature of the reaction, a product results v^hich v;hen filtered, dried and ground will be about 98/^ pure, and contain in excess of 32^;^ arsenic pentoxide. In recent years by industry agreement a red dye has been added to the Lead Arsenate while in the wet state so that aftor processing the prod- uct will in no way resemble an edible powder such as flour or pov/dered sugar. The Lead Arsenate slurry, checked by the laboratory, is fed by gravity or pumps to the drying apparatus which may be in any one of several forms. One common type is the rotary or drum drier where a coat of the thickaned Lead Arsenate paste is picked up on the outside of a steair heated slov.ly revolving cylinder. At the completion of one turn of the cylinder the Lead Arsenate from virhich the water has now been evaporated is scraped from the drum and in dry povirdered form is passed to a grinding mill or pul- verizer before packaging. In other t;^Tpss of driers part of the wat:r con- tained in the Lead Arscr.ate slurry is removed by f^uoh .i.nenhr-nical meojis as filter presses or centrifuges. In this method Goluble saibf; racy be washed out before transfer of the partly dried material to the stsani heated drying ovens. As in the previous case, the dried material is further ground before -4- packaging. During the entire process, from rav; material to the final package form, each stage in the manufacture of Lead Arsenate is carefully watched by sMlled chemists. Current Outlook for Material. Since both Lead and Arsenic have uses in industry in addition to the' manufacture of insecticides, much effort has been spent by rav; material producers to insure a steady, even supply of these tvro materials. In normal times thousands of tons of both Lead and Arsenic are imported into this country to bolster our own production, as well as to provide rav; material for insecticides vj-hich are to be exported to other countries. The present war has cut off much of our imports of raw material and f le tremendous production effort being put forth by this country has added to the strain on our raw material reserve. In addition. Lead and Arsenic have a number of important military uses which must be filled. At present both materials are allocated by the V'far Production Board to the sev- eral industries using these raw materials in their manufacturing processes. Because the protection of food is an important part of our war effort, the use of Lead and Arsenic for insecticides has been given careful consideration, and sufficient raw material has been provided to take care of the essential needs in respect to food crops. It is expected that this will continue sjid that our insecticide supply will be sufficient to meet the needs of our in- creasing agricultural program. The insecticide industry is making a concerted effort to maintain the flow of stocks to the fruit grov;ers and at the same time pointing out the necessity for conservation and careful use of the sup- plies available. Each of us has a part in this all-out effort and clo^e cooperation between the manufacturer and fruit grower will assure adequate and timely supplies to moot all essential needs. DO_YOU_KmM That the annual consumption of fruits and vegetables in 1920 was 384 pounds per person? In 1941 this had risen to 445 pounds per person, an increase of approximately 16^^.

It vdll provide for everything from high explosives to pontoon bridges. That the number of active farm 770rkers on New England farms on June 1 totaled 259,000? This total is 6% more than the 245,000 farm v/orkers of a month earlier. Of the total number of farm workers, 169,000 wore family members ivho worked without receiving cash wages and 90,000 were hired workers. That weather conditions were highly favorable for scab infection in apple orchards this season betvreen May 6 and 17? The following data pre- pared by 0. C. Boyd helps to explain why mur.y orchards bocame infected during this period. Some of these rainy periods were state wide. -5- Date of Length in Appearance of Rain (May) Hours Tree Stage Scab (May) 6-7 36 Mid-bloom 21-23 12-13 14 Calyx 25-26 16-17 16 pre-lst Cover 27-30 That large quantities of vitamin Bl which exercises a beneficial effect on the hixnian nervous system have been found by Yale botanists in the buds and leaves of many common American trees. The buds of oak, red maple, horse chestnut, elm, sycamore and white pine trees are said to contain heavy concentrations. That there is a close relationship between the wetting power of a spray mixture and its retention on the sprayed surface? The wetting power of the spray solution is an important factor in its efficiency either as a contact or a stomach poison. A technical paper on the above relationship has recently been released by the Bureau of Entomology and Plant i^uarantine. That three-fourths of the world's 2,000,000,000 people depend so heavily on potatoes and the cereal crops for food that their bodies are likely to suffer froia a poorly balanced diet? The United States viith 130,000,000 people is the largest national group in the v/orld to enjoy a diet composed of as low as 30-40;;i' cereals and potatoes. Ail of Asia excepting Japan lives on 80-90^0 cereal and potato fare. Southern Europe and most of South and Cen- tral America eat 60-70^ cereal and potatoes, and the rest of Europe from 40-60^. That fruits may be successfully canned without sugar? Sugar does help to preserve color, flavor and texture although according to \7. R. Cole fruits may be successfully canned v:ithout sugar as far as spoilage is con- cerned. If canned v/ithout sugar the fruit should be packed in jars, using the usual amount of water and processing for the length of time ordinarily prescribed. That a Hew Jersey concern has as its slogan, "The Juice of Every- thing That Grows?" This concern squeezes juice from grass, nuts, and some 250 other things, for shipment to many disteint points. That we have been using about half the world's total output of rubber every year? Almost 98/^ has come to us from the Far East, 54°o from Maiaya, 36Jo from Netherlands East Indies, GF/l from Ceylon, and 2fb from other places. That about 20,000,000 non-bearing or only slightly bearing apple trees under 10 years of age should be growing in this country to maintain the bearing acreage? Apple trees have passed their period of greatest use- fulness as commercial producers in most sections of the United States by the time theyaro 40 years old. Approximately 70,000,000 bearing apple trees are required to produce an apple crop of desirable size. That the "red stele" disease has greatly reduced strawberr;/ pro- duction in southeastern Michigan? A recent report in a Michigan nev/spaper indicates a reduction of at least 50^o. In some plantings it Virill run as high as 75-'. -6- That one ton of fertilizer produces on the average 85 bushels of wheat, 217 bushels of tomatoes, 46 sacks of peanuts, 2 bales of cotton, 125 bushels of corn, 130 bushels of snapbeans, 185 bushels of potatoes, 53 bushels of soybeans, 1370 lbs. of tobacco, 8,000 lbs. of milk or 1,000 lbs. of beef? These figures were obtained in two surveys conducted in 1928 and 1938 among 80,000 farmers. Each one was asked to estimate the yields with and without fertilizer for one or tvro important crops. That low quality waste hay or grasses unsuitable for feeding pur- poses are almost ideal for mulching purposes and provide an excellent sub- stitute for fertilizer materials iwhich are now either scarce or una-^^ilable? In some cases such mulching material may be had for the hauling. A recent report tells of one town hauling many tons of hay from roadsides to the town dump. Any nearby fruit grovrer might have had this material for the hauling. That strawberry yields are being greatly increased in Indiana by irrigation? One grower harvested over 900 crates of U. S. No. 1 berries from four acres under irrigation in the 1941 dry season. (ind. ave. 50 per A.) That thinning of Yiealthies even as late as mid-July will greatly increase average size of fruit? A few years ago a heavily loaded YiTealthy tree in the iJ.S.C. orchard was divided into three sections, one of which was thinned July 5, one July 25, and one August 20. By harvest time, the apples from each section had sized as follows: 3" and up 2 3/4" - 3" 2|" - 2 5/4" July 5 20^ 34?? Z^% July 25 % \&f. 56% August 20 1% 5% ZA% That a lime distributor had been in use on a Sudbury farm for the past 40 years. V/hen we visited this farm recently, we found the owner giving it a thorough cleaning. He reported that it is still in perfect working order. Apparently it pays to take care of farm machinery. That the life of spraying equipment may be considerably extended by using plenty of oil and grease, keeping chains and V-belt in proper ad- justment, flushing outfit v;ith clean water after each spraying, protecting sprayer and hose from weather xvhen not in use, throwing tractor in and out of gear with care, preventing hose from rubbing on wheels, and from kinking, and by conserving accessories made of brass or aluminum? The reader can add other "Dos" and "Donts." NOTES FROM NEV7 :IAI.'IPSIIIRE MEETING Following are threo items gleaned from the Journal of the N. H. Horticultural Society covering the annual meeting of November 19, 1941. ^^^ YiqI'^ ,^s_ /■^A^'^^^'^, A", spray program. A. F. Yeager and C. R. Cross reported on the yiefd of appl'e trees in the Univ. of N, II. orchard, some of which had been sprayed continuously with Lime Sulfur and others v/ith Flotation Sulfur during the past 7 years. The trees which received Flotation Sulfur had yielded one to three bushels more per year than those which received Liine Sulfur. (2) Coloring of fruit. M. B. Hoffman, in discussing the subject -7- "Balancing Production and Color," offered this explanation of the coloring of apples during cool weather: The temperature preceeding and during harvest has a pronounced effect on color development. Regardless of the size of the crop, relatively cool temperatures increase color. The effect of temperature may be explained by the fact that during cool nights the loss of sugar by respiration, one of the life processes within the plant, is loss than at higher temperatures. Hence the sugar reserve from which the pigment (antho- cyanin) is formed, is increased at the lavier temperature. Cool temperatures result in about the same conditions as those cultural practices vdiich promote early maturity, namely, a hardening of the tissues, accumulation of sugars and high color. (3) Mulching. J. H. Gourley in discussing the subject, "Some Recent Discoveries witli Orchard Soils," stated that the conservation of mois- ture is generally considered to bs the chief benefit of a mulch. Vifithout minimizing this effect he pointed out the accumulation of plant nutrients under a mulch. Available potassium is quite high from 24 to 32 inches beneath the heavy mulch in two of the Ohio Station orchards. An adjacent cultivated area and an unfertilized field plot are notably low in available potassium. In addition to potassium, otlier elements are also accumulating beneath the mulch. Calcium is higher in the surface three inches; phosphorus is about 8 times as high in the surface soil beneath a mulch as in the cultivated area, and boron is definitely high<3r in the surface soil but not so below a depth of 3 inches. Other elements and even grovrth promoting substances may be present in larger amounts to explain in part the superior behavior of trees which are grown under the mulch system. NOTES ON THE HARVEST LABOR SITUATION meeting At a recent/of Middlesex County fruit growers all angles of the labor situation wer~carefully considered. Thirteen of the larger growers reported a total of 177 workers needed during the harvest season. The num- bers ranged from 0 to 28. Quoting from the report of this meeting by County Agent Agnew, "Most growers eported paying by the day. Last year boys were usually paid by piece (mostly ten cents) and per day, ^4.00 to |5.00. For good men 60/ an hour should be paid. There are 500 to 700 state highvmy employees in the state who may be released for picking, provided they are paid at the same rate - $6 per day. The local highway men are not so numer- ous in some sections. In local towns the selectmen should be contacted by the growers themselves. Conscientious objectors in army will not be avail- able for many roasons. F.S.A. nigrsttory labor camps will not be available. No funds for moving thorn and they never go above southern Connecticut or New Jersey; our season is tno short for them. The general feeling is that the boys in the army camps have a job to do, that of winning the war, and the fruit groivers should not ask for tlieir release. "The greatest source of labor was thought to be part-time workers from mills, quarries, etc. The Emplojauent Service men are to contact some mills around Lowell and Fitchburg to find their working hours and the possi- bility of their help during harvest season. The Employment Service is also listing all available fruit pickers at their offices. Labor will be scarce and sometimes hard to got at the right time. However, many people vdll work in orchards if they are paid a decent v/age. The rates of 7,8, or 9 cents per bushel should be forgotten. A price of 10 to 12 cents will bring pickers. If we stop to consider, two cents a bushel more will give us a much better -8- grade of pickers and we ^vill have much better looking fruit going into storage." The following timely suggestion concerning harvest labor is offered by Lawrence Southwick in the June issue of the American Fruit Grovrer: "Undoubtedly, successful use of harvest sprays should aid northeastern orchardists materially in their harvesting operations. This is especially- true with the larger growers of Mcintosh. The period between fruit maturity (good color, size, quality) and normal fruit drop is limited, and this fac- tor will assume added significance in the face of a harvest ir,boi- snortage. Here then is where harvest sprays should fit into the pfcturo by prolonging the picking period, thus enabling growers to bettor handle their crops with the limited and in many cases inexperienced labor v;hich will be available." SOJffi FOLIAGE INJURY REPORTED FROM SUMffiR USE OP D N In a numb'-.r ?f Massachusetts orchardf. i^.here a heavy infestation of European red mito ha-s ar^peared, growers are using or are considering the use of D N -■ ].ll which is av.pLied as a spray, or •':i-i-. U - 4, a dust ma-oerial. The results from the standpoint of red mito c-.;in.rol are -^jcicij gratifying al- though some injury ho foj.iage has been reporof.i. One grower who applied the dust when the tem^jjvature v;as up to 80'^ and th? relative humidity around 80^ found the foliage' somev.'hat dpjaaged in those parts of the tree vjhich received a direct blast from the duster. The sa::ie i^ ciuo where growers have applied a spray and ha\-e operated a spray gun too close to -uhe tree. From Hew York State the following vra? rep-Ji'ted by R. VJ". Dean of the Experiment Station, Jun-^ 27: "This material (D I! - 11-- ) has been recommended for sur^imer ccnt.vi'^l cf the European red mite. The mtinvfac-:urer cautions against its use undor high temperature conditior.e 'rer used D N - 111 on Mcintosh and Cortland with an apparent good cleanup, but noted some leaf scorch; spray applied under hot conditions and close gun v;ork." NAIL SUPPLY TO BE ADEQUATE Fruit grov/ers should have little difficulty in getting nails for apple boxes in viev; of a recent ruling by the ViTar Production Board. Quoting from Hoosier Horticulture, "The Y/ar Production Board has ordered the produc- tion of necessary supplies of nails, including fruit box nails. Earlier it appeared that purchasers of nails might be required to obtain priority ordorsj ivhich would have resulted in a groat deal of confusion. This priority plan has been discarded following presentation of evidence, and dealers nov/ will be able to accept orders from fruit growers vjithout the necessity of the grower filing an application, " SUGAR FOR EOy\E CANNING Home canners may now obtain one pound of sugar for every four quarts of finished canned fruit. An additional pound per year for each person in the family may be obtained for making jams, jellies, preserves, and fruit butters. One purpose is to encourage canning instead of preserving because a less amount of sugar is used. Rationing for fruit canning will be on the basis of the amount of home canning a family unit has nonnally processed, availability of fruits, and related factors. This information is presented by Secretary Howard Russell in a recent issue of The Farm Bureau in Massa- chusetts. Applicants may obtain certificates by filing OPA application form R-315 v;ith the local board. They must supply the following information: 1. Naiiies of consumers for whom application is filed and serial numbers of their Y>ar Ration Books. 2. Number of quarts of fruit canned last year. 3. Number of quarts of fruit in their possession. 4. Number of quarts of fruit thej'- intend to can. 5. Vfhether sugar is to be used for preserving. 6. Excess sugar supply on hand when Yifar Ration Books v/ere issued. No sugar allotted for fresh fruit caiining may be used for jams, jellies, preserves and fruit butters. Sugar obtained on stamps in Tmr Ration Books may be so used. If sugar alloted for home canning is not used in accordance with regu- lations, stamps vrill be removed from V.'ar Ration Books to cover sugar improper- ly used. (Source - V/ar Letter for Agriculture, 5/25/42). THOUGHTS AND AFTERTHOUGHTS In response to our "A penny for your thoughts" item last month, several have appeared. Some are too difficult for a spur of the moment discussion and others are too late to classify. So we have decided to post- pone all of them until next month. The items include cause of strawberry 'hubbins,"uses of agricultural materials in the defense program, and a number of peculiar symptoms appearing in apple trees this season. NICE-A RED OPPULI A few weeks ago we saw some very high colored apples of familiar appearance in an eastern Massachusetts fruit stand. Pretending not to recog- nize the Ben Davis character of the apples, we inquired, "V^hat variety?" The proprietor ansv;ered, "Gano. Dey eat like-a da Mcintosh." He probably meant that both varieties grow on apple trees. THERE'S A BOm IN YOUR BARNYARD This striking suggestion appears in an advertisement of a prominent farm machinery firm with this explanation. "It's a dud, now. Just a pile of junk. It's your scrap metal. Rusting away and no earthly good to you or to the courageous man fighting this war. They need it. Their lives depend on it. Your lives depend on it. Let Uncle Sam load this bomb for you J Scrap metal makes munitions. A one-ton bomb requires 500 pounds of it. A 75 mm. .10- howitzor takes half a ton. And the nills are not getting enough scrap metal to maintain the steel production df^manded by war industry. By far the biggest pile of scrap metal left in America is on farms. Three million tons of it or more. And it's going to take every pound of this scrap to win this vmr. That's vihy it's up to you to collect all your scrap and get it moving before you do anything else. It may take a day or two of your time, but until it's done, there is nothing you can possibly do that's more important." Let's get in the scrap. CLASSIFICATION OF FRUIT GROYJERS BY SELECTIVE SERVICE Major Alan 3. Shepard requests the State USDA VJar Board to assist him in making reco::imendations for the deferment of men in the fruit industry. Each member of the Vfar Board had been requested to sond m his reply to the State Office on this subject, and an attached -letter ^/as prepared and fur- nished to him in answer to this request. The reply inHi^ates that fruit growers should be classified as of distinct importan'?3 from two standpoints: (1) The importance of the fruit growing industry in Massachusetts, and (2) The contribution of fruit to health. It was recommend-id that only those persons who were engaged in the fruit industry in a managerial or technical capacity be considered as essential. In a recent letter to a fruit grower, Roy E. Moser, Extension Economist, outlines the situation as follows? At a meeting in Viorcester in January, Colonel Charron, head of the Selective Service in Massachusetts, was present. The deferment of farm v/orkers vms discussed with him and he explained that there was no blajiket occupational defe^-.-aent, that each in- dividual oaee was considered solely upon the circu'.istanGOs and conditions around that case. lie further explained that certain agricultural products such as milk, eggs, certain vegetables, etc., had been designated by our Gov'irnment as essential food products and a substantial increase in their production had been requested. Consequently, if a ft^rji.rjr is engaged in the production of one or the other of these crops he should get particular con- sideration by the- Selective Service Board when some of his help is concerned. It was pointed out to Colonel Charron that fruit, tobacco and onion farms and some (5thers were apparently not included. He said that was true but further pointed out that he thought that all agricultural proauction should be care- fully considered. Each individual board largely makes up its own policies. It is difficult to lay dovm blaioket rules to these boards since each case ;vhich comes before the board is an individual case and circumstances and conditions vary for each case. The local board has a great deal of respon- sibility and authority and if their judgment is wrong the selectee may appeal to the Appeal Board." "BRI1\[G A HANDFUL OF QUESTIONS, A C/Jl FULL OF IJEIGH30RS" One county agricultural agent ended his notice of a meeting with this pointed advice. It seems to represent the spirit of the times. And as we think of thren twilight meetings during tho past fevr days farmers are doing just that. In spite of tire and gasoline shortage fruit growers find a way to get together and talk things over. They lield forth at a hill tovm meeting until after 10 o'clock last Tuesday evening with soft wood boxes for seats and hard problems to chew on. You can't beat a crowd like that.

Going Up Essentials and Non-essentials LOOK AT YOUR TREES Nov; is an o;)portune time to look at your trees and observe the condi- tion of tlie foliage. Leaves should be a healthy j^reen (unless red mite has bronzed them), with no evidence of dead leaf tissue. But perhaps some leaves on some trees v;ill show dead brown areas, or edge burn, or yellowing, or other evidence of malnutrition. In such cases, prompt diagnosis is essential to the continued v/nll-being of the orchard. In ons of our, young orchards at the Experiment Station in Amhorst, evidence of a mineral deficiency is nov/ becoming inoreasingly preval-,nt. In Issued by the Extension Service, V.'illard A. Munson, Director, in furtherance of Acts of Way 8 and Jun,. 30, 1914, Massachusetts State College. United States Department of Agriculture and County Extension Services cooperating. -2- late July, leaves on certain trees began to show yellowing and browning in central spots as well as near the edges. These areas pro;.iptly died and be- came brittle to the touch. C^uite soon, affected leaves began to fall off, especially from the lower portions of growing shoots. At the pres' at time, the orchard is rather generally affected by this j, malady which looks to us like a case of maj^nesium deficiency. This orchard soil was foi^a-irly low in potassium, so potasii hus been applied liberally. The high potassium condition f.t the present time evidently helps to bring out the mag- nesium shortage, which actuall-r may be more serious than the original potash shortage. This is further evidence that we have a deficiency of mf'.gnesium here in Amh'^irst, as roportrjd in •" he May issue of Fruit Notes. There are similf ri jies bttvieen the foliage deficiency symptoms of potassium and magnesium, rvriev^.r, the following differences should be noted. In magnesium deficiency, t- ere Is usually nore or less yellow mottling of leaves^ although not alv/ays aviden- , and premature falling of leaves is typical. These t<:io features are not .'ound in .jotassium d~"ficiency. There are certain other differences which need not be discussed at this time. If any grow^;r thi'iks .hat symptoms of magnesium shortage are showing up in his orchard, l-;t us i.t the Colloge knoi. about it. This holds for symp- toms of other def icioncios also. In short, look at your trees. They will tell you in their own w»y if th ir diet is O.K. , r. xu • i ■' "' — -Lawrence Southwick RELATIQI^ OF YffiATIigR TO RBJ MITE INFESTATION In many orchards the number of over-wint^-ring eggs of the European Red Mite in the epring of 1942 was very small, and the sevf^re infestation of this pest which developed uarly this summer was f- itirelyu.predicted. Our only explanat on relates to the occurrence of ideal weather con- ditions for egg laying at tae time when the few mites that hatched from the winter eggs were ovipositing. It is well known t? at insects have a certain definite peripd in their development for lajing most of their eggs and any un- favorable condition during that period vrill cause them to lay fewer eggs. This year favorable conditions at just the right time induced the mites to lay the maximum number of eggs and to produce a soconu generation \vhich was larger and more destructive than is usually produced by u larger first generation which reaches the optimum period for egg laying during less favorable v;eather condi- tions. In August in many orchards the red mite infestation was only normal, or perhaps below normal, in coruparison v/itli the li.rge population which was present earlier in the sumr ^r. This apparent reduction in the abiindance of the red mite in August can be explained by the same reasoning; namely, that the conditions for oviposition by the second or third generation were unfavorable and only a small number of eggs were laid. At this time also the beneficial predators of the red mite have increased and they are killing a large number of mites and mite eggs. J The lady beetle, Stetiiorus punotun, is the most abundant predator, but the black hunter thrips and th'i Seius spider are also active. After the leaves have been badly bronzed, many mites migrate to greener leaves, and the leaves which shoT/i the most severe injury frequently become almost free from mites. This natural reduction in the mite population in late summer is cer- tainly v;elcorae, but it does not eliminate the need for spraying and dusting when the pest is abundant, because the foliage is usually so badly damaged before the natural reduction occurs that the fruit is likely to be small and vail not mature properly, and the buds may be weakened. ^W. D. Vniitcomb FERTILIZER RATIONING Fertilizer rationing is expected to go into effect soon, with control resting with the manufacturers but depending on supplies. Indications are strong that there will be a serious shortage of nitro- gen which is an important element in the manufacture of ammunition. There will bs some sulphate of ammonia available and probably a small quantity of nitrate of soda but the amount is very uncertain. Most of the available fertilizer supply will be in the form of mixed goods v;ith relatively low nitrogen content. This hits the fruit grower directly and especially the grower using sod culture in some I'orm. It is good business to look forward now to handling the orchard next year on a greatly reduced fertilizer supply. It is impossible to continue a sod orchard in a high state of efficiency v/ithout added nitrogen from some source. ViCith the best market outlook in a decade, any reduction in yield would be most unfortunate. There are a number of things that may help. If there is a supply of poultry manure within reach, get it if you can. Use it in light applications any time after the ground freezes in the fall. Many orchards are being seeded to Ladino clover. Orice well established, Ladino may add the equivalent of 200 to 300 pounds of nitrate of soda per acre per year, and under ideal conditions will do considerably better than that. Hauled-in mulching material may be used to replace nitrogenous fertilizers entirely if there is enough of it, but it takes a little time to make its full effects felt. Discing the sod thoroughly in early spring will help materially, and when it is equivalent to cultivation should eliminate -the need for fertilization for several years or until the sod and the accompanying reserve of organic matter are decomposed. R. A. Van Meter STRAVJBERRY "NUBBINS" Small, distorted strawberries made up a large part of the crop this year in many beds. The trouble was so nearly universal as to suggest strongly that some climatic factor was responsible. One or more light frosts occurred during the blooming season. Since the tips of the developing strawberries emerge from the buds first and are therefore exposed when the basal portions have a measure of protection from calyx lobes, low temperatures might possibly have been a factor. Cold, wet vie&ther has long been known to cause a failure of strawberries to develop at -4- the tips. YIe had plonty of such weather this year. A report fron the Arkansas Experiment Station indicates that large amounts of plant food are essential to the proper development of pistils in the strawberry. The development of the berry is entirely dependent upon the performance caf these pistils v/hich form the hairy covering of the little mound in the center of each strawberry flower. This may explain why strawberries on poor land produce so many "nubbins" and possibly one reason for wet weather causing them, since heavy rains leach available plant foods from the soil and may cause a temporary shortage at a critical time. Wet weather also limits the activities of be^js and interferes with pollination. ^ , ,r „, j. ^ - — R. A- Van Meter CHOKECIiEIlRlLS ?c X-DISEASE If you haven't already killed tiie chokecherries around your peach or- chard, this should bo done right avray, to protect it from X-disease. If all chokecherries are killed for a distance of 200 feet from a peach orcbard, the protection is good; but 300 f'^'ot is bett«^r. The best way to kill chokecherrios is by spraying with a chemical weed killer. There are "'wo t;/pes on the market (see Fruit Notes for June, 1942). Remember these weed killers are not selective. They kill all green vegetation sprayed, so keep the spray off anything you want to save. The leaves of sprayed cherries will die in a few days, but don't mow or cut them until late fall or early spring. Givu the chemical plenty of time to penetrate to the roots and kill the whole plant. The following brief outline will help in distinguishing ohokecherries from the two other closely related and similar species: Common name Black Cherry Rum Cherry Chokecherry Pin Cherry Bird Cherry Scientific name Prunus serotina Prunus virginiana PrunuB pennsylvanica Leaf serrations dull "^ sharp % sharp Dots on stem numerous, small few, lar^e numerous, small Pubescence (fuzz) along midrib of older leaves present ab sent ab sent Leaf shape long, narrow shorter & broader than serotina long, pointed, narrow Fruiting habit raceme raceme OjT umbel V' °4 Ripening season late summer 4 mid- summer mid- summer -5- If there is doubt as to which cherry it is, spray it anyway. The aramonium sulfanate weed killer is very apt to damage spray machinery if the machinery isn't washed thoroughly ii.imediately after use. A little baking soda or sal soda (one table spoonful to the gal.) added to the wash water gives added protection. Never Isave any of this material over night in the sprayer. The plant which makes ammonium sulfamate is now used for governraent work most of the tiva. Therefore, civilian orders have to wait their turn and it mav be difficult to get this material, . „ ri„^i„,, PRIORITIES or HAILS, BARBED YflRE AHD FENCIIIG Nails. Nails are still being manufactured and can be purchased without a priority". It is essential, however, that a farmer anticipate his needs and order nails several weeks in advance. If he fails to take this precaution there is no relief for him. Nails are being furnished on quotas, and jobbers report that they are often out of certain sizes. Barbed Yfire and Fencing. We are informed that barbed wire and fencing can now be procured only on an "AI-A rating. The supplier must have a priority on this kind of merchandise if he expects to replenish his stock. It is our understanding that s ime suppliers in the states of Vermont, New Hampshire and Maine are willing to sell without such a priority. As far as we are able to determine, most of the barbed wire netting and fencing in the state of Massachu- setts is t-.xhaustod and there is little likelihood that it will be replenished for the duration of the war. If, however, a farr:er needs fencing and finds a supplier who has the material on hand, we suggest that he make out form PDl-A and submit his request to the War Production Board at V/ashington, D. C. It is probable that these requests will be filled as long as the supply lasts. V'!. C. Harrington TRUCK TRAI^'SPORTATION Regulations for conserving trucks and tires issued July 23 by the ODT concerning return-hauj-i-requirements have been modified in a way that benefits the fruit grower. A permit of temporary exemption to expire October 31 has been issued to trucks "engaged exclusively in the transportation of farm prod- ucts from a fam or farms to a concentration or storage point, processing or packing plant, dehydrating, brining, i'reezing, or grading place, cannery, mill warehouse, stockyard, wholesale or retail market, or to a rail or u water carrier, or v?hen operating a motor truck engaged exclusively in the transportation of farm supplies to a farm or farms." The National Apple Institute contested the earlier truck order because of an unworkable 'V5/o clause." ADVICE TO APPLE PICKERS The following suggestions are offered to apple pickers by H. A. Rollins and W. P. Judkins of the University of Connecticut: -6- 1. Please be Careful of Yourself -- of the Tree — of the Fruit. 2. 'To'Tic': a^rTXipTe" -~ G~usp' tTie apple in the hand, placing the thumb or forefinger" at the union of the fruit stem and spur. Remove the fruit with an upv;ard motion and a twist of the wrist. Avoid breaking branches and fruit spurs. 3. To Pick the jrop — First, pick the apples you can reach from the ground. lfse"'a~"]!a7j'ier to pick the remainder of the fruit. Pick carefully! Fruit with broken skin decays rapidly. Avoid skin breaks resulting from finger- nail cats or apple stem punctures. 4. Setting the Ladder -- Set the ladder so that both legs rest firmly on the Yi^'^'^nd and the top leans securely against a largo branch or crotch. Place the ladder so that if it slips or turns, it will fall toward the center of the tree. Most accidents come from failure to observe this precaution. Don't take chances! 5. Handling Picked Fruit — Transfer apples from the picking container to the ^ppl'e box with extreme care. Every bump makes a bruise! Apples cannot be dropped i'^to the picking container or into the box without bruising. Place bn::es of picked fruit in the shade of the tree, 6. Care of Equipment — At the end of each day's picking, lean the ladder "securely agiTinst" a high crotch of the tree. Do not leave ladders lying flat on the ^^round. Bring all nicking pails or buckets to the packing house or place designated by tho foreman. 7. Assistance from the Foreman -- The Foreman will demonstrate and explain the' poii't s" 11 s'te'd above . The apple grower is anxious to prevent acci- dents and to assist you in any problems i.iat may arise. Please leave vour name and tele' 'lone number v;ith the F'oreman. Tvro Mir;; apple varieties The Idared, a Vlagener-Jonathan cross, is being introduced in the Northwest this year. It is tlie best of nearly 12,000 seedlings developed and tested by the Idaho Station. Idared is somewhat larger than either parent, bright r^jd in color, tender and juicy, has an unusually small core and is said to be resistant to fire blight and Jonathan spot. Another variety, the Minjon, a VYealthy-Jonathan cross, developed by the Llinnesota Station, looks promising for both home and commercial orchards. Fully matured fruit carries the red staining so characteristic of lYoalthy. Some grov;ers say it is the best apple thus far introduc--jd by the Minnesota Station. (V/e have the Minjon in the Col- lege orchard.) SERICULTURE IN BRAZIL Sericulture, or the production of silk by silk worms, sounds serious. And it is taken seriously in Brazil. The Foreign Commerce Vfeekly ^ays, "Brazil is said to have especially favorable climatic conditions for cultivation of the mulberry tree and breedinr^ of silk worms. In Japan, 2 or 3 crops of cocoons are grown yearly, whereas in Sao Paulo as many as 8 successive crops can be raised, and even 12 crops have been grown in some sections of Brazil." Present v;orld conditions have lent so much encouragement to the silk business that the annual production in Brazil is now about 700 metric tons annually. An agency -7- has been cr<;atod to supply interested parties with mulberry slips and silk worm eggs,, v/ithout Ciiargc. (The only justification for including this item in Fruit Notes is the fact that the mulberry is a fruit bearing tree as well as a source of food for silk wonns.) DO YOU KNOW That certain insects are attracted to some colors more than others? Federal entomologists report that Japanese beetle traps painted yellow are definitely superior to those painted green and white, aluminum, white, light yollow, light blue, dark blue, pink, red, orange, reddish orange, and various shades of green. That it takes as much as 500 lbs. of water to develop 1 lb. of dry \matter in a plant? A more or less continuous stream of water is taken in by the roots and transpired by the leaves throughout the season. The actual araount of v;ater per pound of dry matter varies with different plants. It also varies with nutritional conditions. A plant well supplied with nitrogen, for example, may use water somewhat more efficiently. Thai various fungus diseases of raspberries' are likely to be more troublesome in a dense, drov.'ded planting? There is some evidence to show that a single rov; of canes instead of a wide i.atted rov; will make control of diseases such as spur blight considerably easier. At any rate, the rov; of canes ought not to be wider than a foot or 15 inches at the bottom. That the least expensive mulch material which an apple grower may ob- tain is that vjhich groves between the trees. This material involves a minimum of transportation which emphasizes the importance of treating the orchard soil in such way that a hoav;,' -rowth of grasses, clovers, or other vegetation is en- couraged. That a simple priroiple of physics may be applied in measuring the influence on cedar runt infection, of red cedar trees at different distances from an apple tree? It is a v/ell known fact that the intensity of light varies inversely as the square of the distance from its source. The spores from the cedar apples might be considered as being disseminated in all direc- tions from the red codar tree in the same way that light spreads in all di- rections from a candle. An area 100 feet away would tend to receive four times as nany spores as a similar area 200 feet away. This emphasizes the importance of eliminating red cedar trees near an orchard of susceptible apple varieties. (A IVealthy tree immediately adjacent to a red cedar tree was recently observed. As might be expected, the Vifealthy leaves were almost entirely covered with rust spots.) That the harvest season is an ideal time to evaluate one's pruning methods? The nu:aber and location of small, poorly colorec. apples should remind us which branches or parts of branches need attei..;ion during the pruning season. In older trees, the dovmwar . grov;ing parts of branches are almost always older and are also poorly located from the standpoint of exposure to light. Removal of drooping limbs should receive attention whener-Tir such a tree is pruned. GOING UP J t A recant release to Maryland fruit growers contains this advice; "CLEAII UP sprayers, packing houses, and CHECK UP grading machinery. SIAASH UP the scrap pilo and GATHER UP the junk. SLCH'7 UP on use of money and labor for non-osssntials. CRACK UP idle talk and rumors. BACK UP Uncle Sam in the war effort. BRING UP the grade and pack of fruit, PUT UP a good pack.

Vie will MOP UP on the axis if v;e VfAKE UP, BUCK UP, and get our DANDER UP." ESSENTIALS AND NON-ESSENTIALS M. L. V/ilson, National Director of the Extension S-;rvice says, "Never before in our lifetime has it been possible for our Nation's families, through th^ir choices of v/ays and resources, to play so important a role in determining the fate of all nations. We luust give without stint what the nation needs of these resources; but in giving vie must maintain health and wholesome family life. Success in this undertaking calls for great vdsdom and skill in house- hold management, for ability- to distinguish between essentials and non-essentials."

AS Vffi BEGIN THE HARVESTING OF APPLES — Let's bear in mind that there is an ex- treme shortage of storage space, especially in eastern Massachusetts. This means that many of the applos which would normally go into storage must be mar- keted during tho harvest season. It will bo a calamity if retail stores are stocked with green, scabby, unattractive apples instead of the kind the con- sumer wants to buy. We must have voliune novemont during September and October. Good apples in all retail stores v/ill help tremendously. FRUIT NOTES Volune 6 Number 9 September, 1942 VI. H.

The "Materials Allov/ance" will amount to $1.20 per acre. This allowance may be applied on lime, superphosphate, 0-14-14, or purchased potash. The application of lime should be based on actual needs as evidenced by a soil test. It may be applied on a commercial orchard, pasture land, or on crop land which the farmer indicates will be tilled in 1942-43. It may also be used where a good stand of perennial legumes is growing. Superphosphate may be used in connection with the planting of annual, biennial, or perennial legumes for forage or cover crops, or permanent pastures, or as a top dressing on penaanent pasture, or on good stands of perermial legumes. 0-14-14 may be used in the same xvay as superphosphate. The same is true of potash. The rate of payment for mulching commercial orchards is $4,00 per ton. No limit is placed on the amount to be applied per acre. Rate of payment on winter legume green-manure crops is $3.00 per acre, and on winter non-legume and summer legume green-manure crops $2.00 per acre. If a crop of hay attains a good stand and a good growth evenly distributed on the land, a payment will be allowed for cutting and leaving it on the land instead of plowing or disking it under. Other practices forvhich payment will be made under the 1943 program include the grovj-ing of summer non-legume green-manure crops, constructing di- version ditches, terracing, establishing contour strip cropping, maintaining contour strip cropping, establishing sod v;atenf/ays, and for planting forest trees. MEIY PJ:D PuASPBERRY VARIETY Geneva No. 13618 is being named Milton ajid introduced by the Hew York Fruit Testing Association this fall. Massachusetts grov/ers should find this new variety v/orthy of trial as & late berry. In the College plantation it is a little later than Latham, finn, good size, good quality, attractive, produc- tive, free from mosaic, and more hardy than any other of the New York introduc- tions. A. P. French BEACH PLUMS The beach plum crop on the Cape was practically a total failure this year. In spite of this, considerable progress has been made in the beach plum improvement project. A small plot at East Sandwich, fertilized with 400 pounds per acre of a 4-6-5 fertilizer, had a moderate crop; an adjoining unfertilized plot had no crop. This suggests that even a plant like the beach plum, which grows on the poorest of sandy soils, will be benefited by a little fertilizer. -3- A spraying experiment was conducted using the spray schedule recom- mended in Special Circular 46 of the Llassachusetts Agricultural Extension Service. T'his schedule controlled Brovm Rot very well, freed the loaves from a 'gall maker, and probably helped in controlling Plum Pocket. However, some modifications will be necessary to improve the control of other insects and diseases* As a result of a series of propagation experiments, it was found that the beach plum can be rooted from green wood cuttings taken in early June and treated with a groivth promoting chemical. 67% rooting was obtained in about 4 weeks and plants with well established root systems were produced in 2 months. Plants of several selections were obtained from the Soil Conservation Service and planted at the Cranberry Station at East Vifareham. These will be used as foundation stock for future improvement work. The Department of Horticultural Manufactures showed that both the pec- tin and the acid content of the bea&h plum are very near the lower limit for jelly making. For. this reason, difficulty is sometimes experienced in producing a firm jelly. ' V^ays of overcoming these difficulties vrere worked out and the re- sults published. ___j^ g^ Bailey CONTROL OF PEACH TREE BOREl^ It is now time to do something;; about those borers in your peach trees. Undoubtedly the safest procedure is to stick to the old and tried methods, worming v;ith a knife and wire for trees under three years of age, and paradi- chlorobenzene for trees throe years old and older. The ethylene dichloride emulsion treatment cannot be recommended with- out reservations. Additional information and experience gained in using this treatment indicate that it is reasonably safe under Massachusetts conditions, if properly applied. Experiments carried on in the College orchards during the past two years indicate the following} (1) A broken emulsion can cause trouble. Be sure the emulsion hasn't broken. If it has, re-emulsify it thoroughly. (2) Slight variations in strength or quantity of diluted emulsion will probably do no harm. Vflien double the quantity was applied, injury resulted. (3) Prac- tically 100^ kill of borers was obtained where the material was applied October 15 or earlier; kill v; as not so good after that date. (4) If the emulsion comes in contact with the trunks, injury will probably result. Several yoiong trees wero killed and several others severely injured by pouring the emulsion on the trunks. To play safe, be sure the ehylene dichloride is thoroughly emulsified before use. Follow the directions on the container as to strength and quantity of emulsion, and keep the material off the trunks. For best results, apply on " or before October 15. j. s. Bailey FALL STORAGE OF APPLES The September 1 Crop Report indicates a crop of apples this year in -4- Uassaohusetts of 3,320,000 bushels as compared vrith 2,488,000 bushels in 1941, This is a n increase in Llassaohusetts of 33 percent over last year. In New England the 1942 crop is expected to be 8, 007, 000 bushels as compared with 6,060,000 bushels last year or an increase of 32 percent. The largest inorefeBej in the 1942 crop arc in the states of Massachusetts and Connecticut, From this we caji expect more apples to go into storage this year than last. Many storages that are normally available for ■ apples at this time of the year are requisitioned for government war purposes and the storing of extra amounts of food for transshipment to support our war efforts. Generally •peak- ing, there were about 1,900,000 bushels of apples in storage in New England at the peak of the season. If the same percentage of the crop is stored this year, the increase in production will noed space to take care of about 700,000 more bushels than v/ere stored last year. Thus the peak storage requirements for the 1942 New England apple crop v/ill be space for about 2,600,000 bueheis if the sanie proportion of the crop is stored in 1942, There is some indication that country storage facilities in New Eng- land with a capacity of about 2,000,000 bushels, handled 1,400,000 last year, and had space left over for about 600,000 bushels. Because public cold etpraget are carrying a much heavier load this year and by late fall it is expected that this load will be even greater, it would be well for apple growers to utiliee all the space possible in the country areas near producing centers. The ilt- uation in the terminal market storages is particularly tight and v/ill probably continue so through the winter. It is estimated that last year the pubjlcj storages held 500,000 bushels of the New England crop. It is doubtful that these places will have space to accommodate this amount this year, and at ■ast the public storages could only handle such an amount as would be necessaryfto meet the current market demand. I Recognizing that the storage of apples this fall is a limiting condi- tion, a survey of facilities is now being made in cooperation with the State Department of Agriculture, and these results will bo available in the next tissue of "Fruit Notes," —Ellsworth W, Bell "HONEYDE^V" HOlffiY This year there has been a large amount of honeydew collected by bees. This material is a sweet substance eeoreted by aphidsi leafhoppers and some scale insects. It is collected by honeybees and stored in the combs, as id true nectar. The material is high in dextrins and is therefore unsuitable for the vdnter feeding of bees. Beekeepers who have much of this material in their hives would do well to feed 10 pounds of sugar as sugar syrup per colony jutt before the bees are packed for winter, The presence of honeydew in the combs can be distinguished in two wayii] (l) If the combs are held up to the light and appear especially dark, honeydew is to be suspected, (2) If the honey is uncapped and shows a greenish tinge, there is little douVt but that honeydew is present, Honeydew can be used by man with no ill effects. It is usually used as cooking honey since its dark- color and inferior flavor make it unsuitable for use as table honey, —-Frank R.

The base price is ,20, or ^29,20, depending upon point of shipment plus transportation charges. That pectin, normally used for making jams and jellies, is proving valuable to the Allied Nations for extending the supply of blood plasma for transfusion? It is reported that the British Purchasing Commission is prepared to buy large quantities of this material. A so-called "artificial blood" made from fruit pectin which may supplant blood transfusions in the treatment of shock, is being tested in the Henry Ford Hospital Laboratories. That the Agricultural Marketing Administration has opened an office in Boston to handle Nev/ England apple purchases? The address is Room 609, 600 V/ashington St. (telephone Hubbard 5-675). J. Stanford Larson is the Pur- chase Representative, Purchases are nov; being made of U.S. No. 1 V/ealthy and Mcintosh apples, 2^ inch minimum, at $.1.25 per bushel. That the food habits of 4,860 farm families in Essex, Franklin and Hampshire Counties have recently been studied? Of the families with children, from 70 to 75^ in eacli of the three counties were found to have an inadequate supply of canned vegetables. In the consumption of milk, from 2 6 to 42^o fell below the standard set for good nutrition, while in egg consumption^ 31 to 54^ fell belov/ the recognized standard. 95,3 of the children were reported as eat- ing raw fruit or other Vitamin C-rich food every day. That apples shov/ much more bruising on the average when delivered to chain stores from central warehouses than when delivered directly by the grower? Recent studios in Connecticut reveal the follov/ing differences: 48 samples of apples from central warehouses showed 31.6% bruises and stem punctures, v^ile 24 samples delivered by growers showed only 8,6%. That the indicated production of apples in Nev/ England this season is over 8,000,000, the largest crop since apple orchards were seriously injured by the freeze in 1934? A largo crop of Baldwins accounts for part of this increase. For the United States, production in coiTunercial areas is now placed at 126,131,000 bushels compared vdth 122,059,000 bushels in 1941, That the estimated cranberry crop in the United States this year (756,400 barrels) is 4% larger than in 1941 and 25% above the 10-year average? All cranberry producing states except Massachusetts anticipate a larger yield than in 1941. The yields (in barrels) by states are as follows: State 1941 1942. Massachusetts 500,000 490,000 Now Jersey 80,000 100,000 V/isconsin 99,000 115,000 V/ashington 36,000 40,000 Oregon 10 , 200 11 ,4p0_ _ Totals - 'T25,200 756,400 -6- That Martha's Vineyard has a viild cranberry bog which has been produc- ing cronberrios for about 300 years? This bog is in Gay Head and is given by the Commonv/ealth in perpetuity as the common possession of the descendants of the Gay Head Indian tribe. Following ancient tradition, the day of picking is decreed by the heads of the Gay Head group. The first day of the harvest is exclusively for the Indian descendants. These vdld cranberries are rather light in color, of medium size and good flavor. That this is an ideal time of year to destroy, or at least mark for destruction, peach trees suspected of having X-disease or other virus troubles? J. R. Magness of the U.S.D.A. points out that the spread of X-disease is in geometric proportion to theanount of infected material. Where but one peach tree is affected in on orchard, the spread is slow. But if 10/j of the trees are infected, the spread is rapid. It is much easier to detect virus troubles in a peach tree in late summer or fall than it is in spring. That a liberal application of nitrogen on a soil deficient in certain other necessary elements, will tend to accentuate those deficiencies, as re- vealed by leaf symptoms? More and larger leaves and more terminal- growth, re- sulting from the nitrogen application, will call for more potash, magnesium and other elements. If such elements are lacking in the soil, the leaves will therefore show more pronounced deficiency symptoms. That publications on the fruit industry in each of three South Amer- ican coiontries, Argentina, Brazil, and Chile, are now available? These reports have been prepared by Prod A. Motz of the Office of Foreign Agricultural Rela- tions, (The v;ritor has a couple of extra copies in case any reader of Fruit Notes is interested.) That there seems to be a definite relationship between the acidity of the cell sap of plant leaves and the sensitivity of the plant to injury by sulfur or by copper? The acids resulting from the oxidation of sulfur on a leaf might be expected to cause less leaf injury if the fluid within the leaf is already rather acid, than if it is relatively alkaline. Thus if sulfur were applied to a plant having cell sap near the neutral point, a small amount of acid from the oxidized sulfur might precipitate the plant protein and cause severe injury. Copper, on the other hand, would tend to remain in insoluble form on such a leaf. The following data reported by 0. C. Boyd in Crop Disease Notes several years ago helps to illustrate this relationship. Kind of Plant_ pH of Cell Sap Sensitive to^Sulfur Yes Yes Medium No Sensitive to Coppor Potato Bean Apple Peach 6.4 6,0 5,2 4.0 No No Fairly Highly That the angry thunder of Russian artillery is to some extent dependent upon the. read'justment of soil, management practices in America? By growing a single acre of red clover, and plowing it under, a farmer is replacing enough nitrate of soda or other commercial nitrogen to make the gunpov^der needed for hurling 150 105-mra. shells 9 miles into enemy territory. The roots and stubble of a red clover crop may add about 50 pounds of nitrogen to the soil, or the -7- equivalent of over 300 pounds of nitrate of soda, the old reliable crop stimu- lator now used in powder making. V/.\RTIME USES OF CERTAIN CIIEI;IICAL ELEIvEMTS MEEDED IN A,GRICULTURE Three chemical symbols, N, P, and K, signify for the farmer, three of the fertilizer elements necessary for plant grovrth. Nitrogen, Phosphorus, and Potassium. Four others, S, Cu, Pb, As, signify elements essential in the con- trol of diseases and insects. Sulfur, copper, lead and arsenic play a vital role in the fight against plant pests. Fortunately, all of these r.even ele- ments are still available in one form or another for agricultural uses, in spitf; of the fact that all of them are tremendously important in our war pro- gram. The manufacture of thousands of items needed in fighting a war are ab- solutely dependent upon unfailing supplies of theso elements. To meet the demands of both industry and agriculture will require care- ful planning. If deli/eries to fanners are not as prompt as they might be or if certain materials are entirely off the market in 1943, the enormous demands of the v;ar program must be taken into consideration. D. H. Sieling and R. W. Fessenden of the Department of Chemistry have prepared the following partial list of wartime necessities in which the above mentioned chemical elements are roquiredj Nitrogen - Explosives, plastics, lacquers, vmr gases, signal flares. Phosphorus - "Calling card incendiaries," oil well drilling, baking pov/der, smoke scroens, making gasoline from natural gases, tracer bullets. Potassium - Potassiuni cyanide for case hardening steel, optical glass, metal used as a core in motor valve stems, signal flares and shells. Sulfur - Sulphuric acid for use in explosives, pickling steel, refining "^ oils, manufacturing dyestuffs, mustard gas, plastics, copper refining. Copper - Signal flares, alloys, conducting v/ires, plating of certain metals for resistance to erosion. Lead - "^Inti- knock" compounds, storage batteries (most important), bearings, solder, pigments, dieathing cables. A.rsenic - Signal flares, manufacture of shot, bearing metals, war gases, special alloys. HERE 'S .^.IDEA Tifith apple leaves showing magnesium deficiency symptoms in a nuraber of Massachusetts orchards this season, it is interesting to note the soil con- ditions under v.-vriiich these symptoms sometimes occur. In one Connecticut Valley orchard v/here Mcintosh and Astrachan trees show definite signs of magnesium deficiency, ruts 8 or 10 inches deep made by the sprayer wheels last spring are apparent. This part of the orchard is poorly drained and the trees are shalloiv rooted. Under these conditions trees are unable to take in enough of certain mineral elements, including magnesixmi, to maintain normal foliage. A water logged soil vrith resulting lack of aeration sots the stage for faulty -8- nutrition. Even thoui^h thero are liberal supplies of mineral elements in the soil the tree is unabl& to get them either because the roots have been des- troyed or they are failing to function. Instead of being able to exploit the soil to a depth of 6 or 8 feet the tree must get v/hat it can from a depth of 2 or 3 feet or less. This situation suggests a need for doing something more than applying this or that mineral element. It is easy enough to apply magnesium sulfate around a magnesium deficient tree. It might bo more profitable to drain the soil before attempting to make up the deficiency. And in case the soil is already over drained a heavy mulch may go a long way toward improving growing conditions. In a season of heavy rainfall magnesium deficiency symptoms are likely to appear on a porous soil because of excessive leaching. Thus we may find similar leaf sj^mptoniG in a soil Vvrhich appears to be too vret and one which appears to be too dry. In both cases the tree is unable to obtain its require- ments of one or more min'-;;ral elements. DOBS LIQUID LIIE SULFUR DETERIORATE? A report just received from Robert B. Smith of Eastern States Farmers' Exchange helps to ansvvor this question. Laboratory studies have be'^n made by this concern to determine the effect of freezing on lime sulfur solution. Quoting from Mr. Smith's letter, "Our laboratory reports that the temperature of Lime Sulfur Solution can go well below the freezing point of water (32 de- grees Fahrenheit) before ajriything happens. They found that somev/here in the range between 10 and 15 degrees crystals began to appear on the surface. As soon as these first crystals were formed more and more crystals developed dovm -through the solution as the temperature was gradually lowered. They also found that if the container v/as jarred that the crystals v/ere formed more quick- ly. At about 5 degrees FeJirenJrieit the entire sample became a mass of two types of crystals. One v;as ice and the other a sulfur compound. At this point con- siderable pressure was developed in the sample and this pressure affected the thermometers to the point v;here they became unreliable. I believe that this development of pressure due to the freezing of the solution is probably the most important point in connection with damage which might be caused to the solution. This pressure would, without a doubt, burst or opon the seans in the drum and thus allov; the solution to leak out. Upon thawing the sample, the solution appeared to go back to its original state v/ith the exception of a fev; crystals of Sulfur which remained around the top edge of the solution. As far as the laboratory could determine this solution was per- fectly usable and seemod to be normal except for the presence of these few crystals of Sulfur."

In other words, records of past sul';s and acres fertilized will likely determine the amounts you may obtain for the acreage of crop grown and fertilized this coming year.

A recent survey, made cooperatively with the Massachusetts Department of Agriculture, indicated that apple storage facilities would be at a premium for storing the Baldwin crop. Facilities in the country are generally more able to offer space than warehouses in terminal markets or cities where the demand of the Federal Government for the storage of perishables is very great. Also, t'-.mporury facilitios are often found in the country areas in the foni: of ice companies w ho can remodel some space and laake it available for the storage of apples. The storage situation in the eastern part of the State seems to be somewhat tighter than it is in the apple areas in the Wfistern part of Massachu- setts. This nay be because growers normally depend more heavily upon city storage for their crop than country storage. Another factor which tends to aggravate the situation is the small market movement of Mcintosh out of storage at the present time* If this move- ment could be stepped up, storage space could be relieved for the holding of the Baldwin crop. Vfithout a doubt, a larger proportion of the Baldwin crop will, by necessity, have to be stored in common storage this year. The greater use of common storage v/ill result in a larger volume of the Baldwin crop being marketed during the months of December and early January. In order to make the best of the situation and adjust to the changed conditions, it is expected that marketings of Baldwins vdll be heavier during the fore part of the season and Mcintosh, v;hich are in suitable storages, will be heavier in the latter part of the marketing year. This will make it im- perative that most of the attention be given to the marketing program which will first dispose of the Baldwin crop in the most orderly manner and in suf- ficient time to relieve the pressure on the Mcintosh crop which occupies the better type of storage conditions. From this it would seom that the Purchase Program of the Agricultural Marketing Administration should be directed largely to the marketing of that part of the crop v/hich is by circumstances due to suffer for want of sufficient facilities. Ellsworth W. Bell GOLDEN DELICIOUS AIJD DUCHSSS ON MLLIKG ST OCKS The Golden Delicious apple is evidently' one that shows interesting rootstock responses, especially in its early production.

It would mean about -3- 75 bushels per acre. Of course, in ten years when the more vigorous trees have begun to bear, the story will be different. But Golden Delicious on Mailing IX will delight the back yard fruit grower if he can control the curculio and naggot. With Duchoss the story is quite different. Mailing XVI, which is a standard stock for most varieties, brought Duchess into bearing earlier than the very dwarfing stock DC. These are indications of some of the coraplexities in the clonal stock problem. j. k. Shav/ IJAGilESIUI-I DBFICIEilCY llsntion has been made of the raagnesi'om deficiency in our Experiment Station orchards. There is little doubt that many of our trees suffer from a lack" of magnesium. They look fine until some time in July or early August when, rather suddenly, the leaves may shov/ some yellow chlorosis, dead areas appear and the older scorched leaves may fall while those near the tip of the shoots often remain green and healthy. 'vTe have been v;orking with quick tests to determine what trees are dangerously low in magnesium as v;ell as in other mineral elements. This work has been alternately encouraging and discouraging. Just now we feel that we have a procedure that will show if a tree is deficient in magnesium. Tests from orchards out in the state shov/ some that seem to be suffering from this deficiency. If your orchard showed burned and falling leaves in August and September, it should be looked into. Magnesium ff.rtilizer experiments in a Three Rivers orchard and at the Station have been started and further experiments are planned. j. ].;. shaw POSSIBLE REMEDIES FOR LIAGIJES lUIi DSFICIENCY Several inquiries have come in regarding the procedure to follow in correcting magnesium shortage in apple orchards. There is increasing evidence that quite a number of orchards in this state nay be suffering from this trouble. Unfortunately, an easy and certain solution of the problem cannot be given at the present tLme. In Canada serious magnesium deficiencies in apple orchards have been recognized and studied for about four years. Several treatments have been tried and most of these have been found inadequate to effect quick and complete recovery of affected trees. This seems peculiar since annual crops respond very readily. In a letter from Dr. H. Hill who has carried on most of this magnesiura work, there is some very interesting information. In areas where the deficiency is most severe, the soil is very acid - below pH 5.0. This SQsms to be the case in Massachusetts also. Dr. Hill recommends applying dolomitic limestone on such soils, although he says that several years may elapse before there is any benefit from the magnesium. Surface applications made in 1939 have given no signs of control. For quicker and perhaps only temporary results, magnesium sulfate (Epsom Salt) has been recoiiUiended, Ap- plications of 12 pounds per tree in the spring of 1939 controlled the trouble only after about two years. In 1941, the trees v/ere back to normal. It would seem that probably this is one of the best methods of alleviating magnosiiun deficiency fairly quickly in apples. However, when soils are acid, magnesium limestone should be given to correct th'; pH and thus help to affect a more permanent cure. -4- Dr. Hill reports further that both dolomite and magnesium sulfate were applied in 1941 at the rate of 9 pounds per tree to a depth of 18 inches in numerous crowbar holes without controlling the disorder during the season. Also, a 2^5 solution of magnesium sulfate was injected into the soil by a pov;er sprayer, but again no control was evident in the season of application. In England 400 pounds per acre of magnesium sulfate in 3 successive seasons failed to give control. In New Zealand, soil applications of 2 pounds of magnesium carbonate per tree have given best results, although partial control was ob- tained with 7 pounds of magnesium sulfate per tree. There is also some evidence that spraying the foliage with a 1 or 2 percent magnesium sulfate spray early in the season gives temporary benefit. V/e hope to have more inforjTiation on this problem following our ov/n experiments. In the meantime, growers might well find out if their own orchards nay be affected by a shortage of magnesium. The symptoms, were outlined in a previous issue of "Fruit Notes," aad mentioned briefly i_n/article above. A further chock can be had by sending loaves to us at the College for "quick tests." See your county agent about it. -l-Lawrence Southwick SOIvE STRAY/BERRY OBSERVATIONS A recent bulletin from Iowa stresses the relation betv,feen time of runner formation and production capacity of the runner. As compared with runners rooted in July and August, those rooted in September produced only about 2/3 as much, while October rooted runners produced less than l/S as much. To insure plenty of July and August runners, plants must be set early and given good care, September and October runners should usually be treated as v;eed plants. The sai.ie bulletin presents one more piece of evidence to show that manure is by far the best fertilizer for strav/berries and that oomiiercial fer- tilizers usually are not worth v/hat they cost on soils of average fertility in the northern states. 4 u r. v, "•"■•A* * • r roll Oil FERIvIATE, A SUBSTITUTE FOR SULFUR Back in 1909 apple growers were looking for a substitute for Bordeauj Mixture, The results of many experiments at that time indicated that lime- sulfur solution properly used had advantages over Bordeaux. Lime-sulfur, con- sequently, replaced Bordeaux although injury associated with its use in orchard spraying has alv/ays been recognized in the years which followed. Condemnatior of the lime- sulfur program has been most severe and general in the past 15 yeart and wettable sulfurs have appeared as substitutes. Now substitutes for wettable sulfurs are being considered in view of the limitations of sulfur, particularly (1) the incompatibility of sulfur and summer oil on apples, (2) the unsatisfactory control with sulfur of cedar apple rusts, and (3) the russetting of the apples in certain seasons, which in a large measure is due to sulfur. I After much study, Fermate, an organic fungicide, is now being offered as a substitute for sulfur. It is a fluffy, black powder. The directions for use call for l/2 to 1 l/2 pounds of Fermate to 100 gallons of water arid at this rate of use the price is equal to sulfur. It is reported to be twice as toxic to fungus spores and in this season's use on Starking at Gleasondale it did not cause any fruit russeting. The Hew York (Geneva) Station has reported that Fermate controlled scab on Mcintosh as viell as the dry v/ettables and that no injury resulted from its use with oil and fixed nicotine on Baldv;in. Also, Fermate gave perfect control of cedar apple rust against only 50^;,^ control v/ith wettable sulfur, Fermate is reported to leave no objectionable residue on the fruit and this feature should make its use valuable in some seasons prior to harvest as a protection against lat>'; infections of brown rot, scab, etc. On the basis of this year's work in Massachusetts, the substitution of Fei-mate appears to be the answer to most of the russet problem on Delicious and other russet susceptible vt^rioti';s^^here a spraying program is follov/od. There v/as not enough scab or codar apple rust in tho trees not sprayed with fungicide in our test to pass uny judg-.ient on its fungicidal valuu, E. F. Guba DO YOU Ki.'gv That a single weed plant may produce more than half a million sneds? One plant of hedge mustard is capable of producing enough seed to sow, if evenly scattered, 11 soods on fivory squar:; foot in an aero of land, or enough to sow 3,200 seeds on every acre of a 160 acre farm. In a study of the fol- lowing weed plants - v.'ild Inttuce, tumble weed, purslane,fl6abane, and hedge mustard - seed numbers of individual plants v;ore found to range from 52,700 to 511,208. That the element Magnesium enters into the composition of chlorophyll, the i^reen coloring matter in plants? The molecule of chlorophyll component A, a blue-black compound, has this complicated makeup: Carbon55lIydro2en72Cx2/'Gen5 Nitrogen4Magnesiumi. Component B, a green-black compound, varies slightly in its content of Hydrogen and Oxygen, That an apple ripens 10 times as fast at 85° F. as at 32°? As carbo- hydrates are consumed in the ripening process, carbon dioxide is given off and heat is generated. In terms of British Thermal . Units, a ton of apples at 32° generates at least 660 B.T,U. per day while at 85° it generates at least 6,600 B.T,U. per day. apple That a 2;^ in. /may shrink as much as 50Jo in the process of peeling and coring, while a 3-| in, apple shrinks only 10 or 12^o7 That the optimum soil acidity for blueberries is very near pH 4,57 R. C. Collison of the Geneva, N. Y, Agr. Exp. Sta. offers the following sug- gestions for acidifying a sandy soil which is not sufficiently acid for the grovj-ing of blueberries. He says, "Every ,1 pH over pH 4.5 will require ,075 -6- pounds of sulfur spread over an aroa of 100 square foet. For oxaxaplo, if the pH is 6.5, it is 2 pH units ovor the 4,5 optimum and so would require 20 X .075 or 1.5 pounds of sulfur per 100 square feot." He cautions against the use of sulfur • vrithout knowing the soil thoroughly. Carc^ful tests of acidity should be made before any sulfur is applied. That the meadow mouse population in most llassachusotts orchards is unusually high? Robert 11. Borg of the Fish and VJildlife Service, says, "Many Massachusetts orchards are providing ideal habitats for an abundance of mice. If climatic conditions are normal this fall v/e may expect damaging populations of Microtus. Mice v;ere present under nearly every tree examined in 25 mulched orchards in 4 counties (Vforcester, Essex, Middlesex, and Franklin). Food and cover conditions v;ere ideal everyv";here. In one better than average 1 acre habitat (orchard) in Middlesex County 28 meadow iiiice were taken in one day." That highly favorable weather conditions during September in the important apple producing areas of the Northeast have brought about a further increase in the apple crop? The October estimate for New England is ZT/a above the 1942 crop. The United States crop is :iow placed at 128,386,000 bushels which is nearly 2 per cejit above last month's estimate. That apple storage conditions in an underground stravir lined pit are almost ideal? Vuth relative humidity around lOOJo and v;inter temperatures a little above the freezing point, v;e have very favorable conditions for apples which would otherwise shrivel in an ordinary cellar. The writer remembers Russot apples stored that way on the homo farm in Hichigan. On removal from the pit in April thoy wero unbelievably crisp. V/ith a shortage of storage this fall somo growers are considering a return to this old method. TESTING ORCHARD SOII^ FOR. ACIDITY Ev-iry fruit grovifor in Massachusetts sliould be interested in maintain- ing tr°e vigor through the use of . materials other than nitrogen. Present re- strictions on nitrogenous fertilizers make this problem increasingly pressing. We must devise substitutes for the annual spring tonic which we have learned to administer through the use of nitrate of soda and other high nitrogen forti- zers. ViThile we have dosed our orchards \vith nitrogen we ha-^e paid little or no attention to the increasing acidity of the soil, a condition brought about by^ liberal applications of sulfur in the form of sprays or dusts. Many orchard soils are now so acid that only the more acid tolerant plants vrill grovf. Grasses of all kinds have in many cases disappeared from the area beneath the branches. Under these conditions an application of potas)i or phosphorus may be partially wasted since these elements may not remain in available form. Furthermore, the scanty cover crop results in a very slight addition to the supply of organic matter. In a few words, the problem may be summed up as fol- lows: Orchard soil improvement may be brought about by (1) a test for soil acidity, (2) an application of high magnesiuin or dolomitic lime as needed, preferably harrov;ed in, and (3) the establishment of a leguminous cover crop. We need a state wide carapaign on the testing of Massachusetts orchard soils for acidity. A liberal application of lino, long delayed, offers a partial j solution of tho tree vigor problem. This practice should supplement or precede the bringing in of additional mulch material. Volume 6 In This Issuo: FRUIT NOTES number 11 November, 1942 Vf. H.

(3) Take care of the sprayer. (4) Mulch straw- berries. Let's make sure, first of all, that the apple crop is protected against low temperatures we are certain to get during the next month.

Tho stage is sat for heavy mouse damage bet^/een now and spring un- less vie do something about it. A heavy grov/th of grass in the orchard pro- vides ideal quarters for mice v;ith some protection against natural enemies. House runs are very numerous in many Massachusetts orchards. We cannot stress too strongly the necessity of baiting v^ith either zinc phosphide treated apple cubes or crushed oats wherever signs of mice are in evidence. If there are many drop apples in the orchard the grain bait is likely to be more offectivo than the apple bait. Spraying season worries v;ill be lessened in 1943 if v/e take good care of the sprayer this fall. The sprayer should be drained at least, to make sure that nothing is damaged when the fii*st real freezeup arrives. And if time hangs heavy on any fruit grovrer's hands a start should be made on overhauling the sprayer and on making a careful checkup of needed repairs. Me may have to make the present sprayer last several years. The time has also arrived for mulching the strawberry planting, A layer of strav/ before the ground freezes hard may be one of the best vmys of insuring a good crop of strav^berries next spring. Mulching protects strav/- berry plants from heaving, prevents croi/m injury, offers some protection against spring frosts, conserves moisture, and keeps the berries clean. On a singl-'i entarpriso farm, ivhore anything like a normal supply of labor is available, there is less excuse for delay in doing essential tasks. And although fruit growing is a highly specialized enterprise to which un- divided attention must be given at certain critical seasons, most fruit growers have one or more other enterprises to supplement the farm income, Ilavin;^ tv;o "irons in the firo" is an ideal arrangement, so long as one is not allov;ed to get cold v/hilo v'e liainr.ior at the other. The v^hity collar boss of former years is donning overalls for the duration. On many farms two men will do the T;ork \/hich throe or four did prejviously. Longer hours, better planning, and noro shortcuts will t'jnd to keep tho fruit ontjrpriso going at top speed. DO YOU Kiiav That many of our corai.ion varieties of fruits are, in reality, hybrids developed by crossing two distinct species? The Kieffer pear, for example, is a cross betv/een the ordinary pear (Pyrus communis) and the Oriental pear (P.serotina). The purple raspberries, including Sodus, are the result of cross- ing the red raspberry (Rubus idaeus) and the black raspberry (R. occidentalis). Certain varieties of grapes, including Brighton, are crosses between the European Grape (Vitis vinifera) and the Fox Grape (V. labrusca). That the roots of an apple tree often extend outv/ard at least tvdce as far as the branches? After the flood of 193G, measurements were riiade of a 9-year-old apple tree, the root system of v/hich v;as partially exposed by ero- sion, Vihile the branches reached outward a distance of only about 8 feet, one root actually measured 25 feet in length. ■3- That the totS.1 leaf area of a larj^e forest tree i.my anount to an acre or more? Yeai*s aj^o, a Harvard professor estiraated that the u-ashington Elm in Cambridge had approxinately 7,000,000 leaves with a total area ai.-iount- ing to 200,000 square feet, or almost 5 acres. That a strawberry plant should be mulched before the temperature drops much below 20''^ F? If left unprotected until the ground freezes hard, injury to the crown and a reduction in yield may occur. That apple concentrate is novi bein;^ used as a substitute for glycerin in the manufacture of cigarettes? One manufacturer is reported to be inter- ested in obtaining a large quantity of this product, a six to one concentra- tion of apple juice. That dehydrated appleg v;eigh only one-seventh as much as raw apples and can be reconstituted readily to make apple sauce, pie filling or fruit for eating with cereal? In the case of carrots, 6 orates, v:eighing 19G pounds, yields 17 pounds of dehydrate, enough to fill t\;o S-gallon cans. (Fr^m "Country Life in /sritish Columbia"). That there were, according to a July count, 4,323 frozen-food locker plants in the United States? This is an increase of 700 over last year. That the fruit tree leaf roller has replaced the codling moth as En3my IIo. 1 aiioni^ Kickapoo Valley (w'isconsin) apple growers? Injury ranged around 30;^ in sprayed orchards in 1941. --L. Southv.-ick That a new high point was reached in 1941 in the amount n" co;;Tmercial fertilizer used by American farmers? The total figure \/as 8,400,000 tons, an increase of 7;;^ over 1940. The previous pe&k v/as in 1930 \;hen sales totalled 8,222,000 tons. (From "The Fertilizer i^eview"). That every time a 16-inch „un is fired, 120 pounds of nitrogen goes back into the air from v/hich it cai:ie. The nitrogen needed annually by our farmers would, if converted to explosives, be sufficient for v;ell over 7 mil- lion 16-inch shells. (From Dupont Agricultural Ilev.-s Ijetter), ■ That the ITeTir England honey crop this year amounted to about 1,706,000 pounds or 27)"j more than in 1941? The nu:;iber of colonies of bees is about 18^o larger than the 45,000 reported last year. The honey c rop in the United States was 13^j smaller than last year, or 179,653,000 pounds compared with 206,551,000 pounds in 1941. (l^rom N. E. Crop Reporting Service). That 10,934 cars of apples were purchased last year by the Surplus liarketing Administration? Virginia led with 2,269 cars, followed by New York v;ith 1,605; Y/'ashington^ 1,513; and Ohio, 1401. Massachusetts marketed 96 cars throuji this agency. That approxinately 1200 cooperatives handling perishable comi.iodities vrere in operation in the United States during the year ending July, 1940? Products valued at O289,.000,000 v;ere marketed for IGCjOOG producer-members, (From Eul. 49, Fan.i Credit Adiiiinistration), -4- That the russet for/.-iation in th*? skin of an apple is nade up of cork cells, the same basic material found in bottle stoppers? In the case of a Roxbury Russet apple or a Dose pear, the russeting develops normally. But abnormal russeting as a result of injury to the youn^ fruits often occurs on apples and pears v/hich normally have a smooth skin.

LIAIIITAIIIING TREE VIGOR IN SPITE OF MTROGEN ^"IORTAG_E Tree vigor must be maintained if our orchards are to produce large -5- annual yields. If a starvation pro^ran is follov/ed, apple trees t^radually assume a biennial bearing habit and the yields/so scattered that spraying becomes a dubious investment. In order to justify a thorough spray program and insure a steady flow of a needed food trop, v.-e must encourage a set of fruit every year. Fruit trees can be kept in good vigor even tliough the co;nmercial nitrogen supply is greatly reduced. R. M. Donaldson, Extension Agronoinist, 'i.iakes these su^j,_;estions: "In viev/ of the nitrogen shortage, orchardists should supplement the commercial supply by doing one or more of these things: (1) Using more poultry manure, (2) activating latent nitrogen reserves in the s.">il by plov.'ing or disking alternate strips, and (o) subsequent seeding of strips to legume mixtures, including Ladino clover, thus addin^j nitrogen by fixation, and (4) by mulching. Lime and 0-14-14 or 0-20-20, obtainable throuj^h the Agricultural Conservation Pro^rai.i, fit into t?ie le^^ume seeding project. Fertilizer combinations such as 7-7-7, coi.r.ionly used by orchardists in years past, will not be available. A 4-9-7 grade has been authorized as the nearest substitute. This material, applied at the same rate as the 7-7-7, will supply the equivalent of phosphorus and potash, but not of nitro^,en. The only other grades offered for sale this year and possibly less desirable for most orchard purposes are these: (1) 4-10-10, or a higher analysis, 6-15-15, (2) 3-12-6 or 5-20-10, (3) 4-12-4, and (4) 3-12-15 or 4-16-20. There v;ill be available for tobacco, only, a 5-3-5 or e-S-e. llo-nitrogen grades will include 0-14-14, 0-20-20, 0-9-27 and such offerings of super- phosphate and muriate of potash as are usually sold." yAJlJ_AT^ION IN TOXICITY OF LEAD .liRSSnATE SPILIYS Quoting from "Food for Victory v;ith Pling Apple," an Extension pub- lication prepared by V. T.". Kelley of the University of Illinois, "During the dry season of 1941, codling moth was very hard to control. Several reasons can be given for this difficulty, but tvra factors were especially important. (1) Dry seasons are very favorable for codling moth development, and (2) lead arsenate sprays are less toxic in dry seasons. During the wet season of 1942, these tv;o factors v;ere reversed. Rainy periods made it more difficult for the codling moth to survive, and the toxicity of the lead arsenate sprays in- creased because of the formation of a greater amount of free arsenic (arsenic acid). Tills increase in free arsenic not only makes the lead sprays more effective, but als^ causes more spray injury to fruit and foliage," These statements offer a partial explanation of codling moth behavior in Massachu- setts and of variations in the amount of spray injury. SAVE TIRES AIID TRUCIIS A leaflet issued by the Hass. State College Extension Service under this title puts the problem Squarely up to the farmer in these words: "Every Mass. farmer hag the vital responsibility to save his tires, truck and car and make them last for the duration. To win this vmr we must pool our autos. This v/ill save tires, save gasoline, and save trucks and autos. These are -6- necessary to van and i^ain a r/orld peace." Here are 10 su^^^estions, soiue of wldch vill apply to every farm: (1) I'eep tires and trucks in rood condition, (2) Organize transportation pools, {Z) Drive carefully and less often, (4) Reduce driving in bad weatlier, (5) Keep larger supplies on hand. (6) Have plenty of storage space, (7) Elim- inate pleasure trips, (3) Pick up nails, pieces of board, broken t_,lass or jagr;ed rock wherever trucks and c ars are used, (9) Keep an eye on your tires and raake sure your spare tire is properly inflated, (10) Plan a conservation prograa v;hioh v;ill prolong the life and usefulness of your transportation facilities. G OPPER JN_ ^^GRIC ULTUHE A step toward conservation of copper in agriculture has recently been taken by the 1j"ar Production Board, according to R, j, Haskell, Extension Plant PatnolOt^ist of the U.S.xJ.wi. The order provides that on and after Oct- ober 1 producers and distributors iiust be authorized to naVce deliveries and that those accepting delivery shall use copper coinpounds only for specific purposes. An individual fanier buy^-r at the tine of purchase or placing his order will certify in T;ritin(j to his supplier that the ainounts he obtains will bi used solely for agricultural purposes--that is, fungicides, bacteri- cides, pres-;rvatives, etc. The United States has been the largest producer and consumer of copper. Our estimated supply this year, 2,571,000 short tons, is greater than the supply of the v;hole v/orld in 1938. Every pound of this copper is needed for essential v/ar purposes, a mediui.i tank takes almost half a ton; a Flyin^j Fortress, a ton and a lialf. Ariiiiunition is one of the lari^est us-jrs. ilost of the copper used in agriculture is in the form of fungicidal sprays and dusts. Specialists and county agents v/ho advise farmers and ^roi/ers i/ill \iish to emphasize the need for conservation and wise use of copper fungicides. Sprays and dusts are sometimes wasted by applying when not really necessary. Therefore, accurate diagnosis of the disease and cor- rect timing of tlie application are important. Research workers have pointed out that in many cases the strength of the copper in the sprays and dusts can sometimes be reduced. Attention siiould be given to this possibility and also to the use of alternative fungicides, especially those containing sulfur. APPLES i-UID TliE WAR FOOD PROGiUII In a recent issue of "Country Life in British Columbia," Roy F. Hen- drickson. Agricultural Marketing Administrator, makes these pointed statements ' about apples: "Apples like many other foods, serve on two fronts, at home and abroad. Apples no\i are being used to help feed our armed forces and fighting allies. Id'hen it comes to shipping across the oceans, hov;ever, we are limited to the dried and canned pu-oducts which require a minimuia of space and handling. For these reasons, fresh apples are no longer on our foreign shipping list. In our war food program, fresh apples vd 11 play their most important role here on the home front. Our civilization must eat more fresh fruit and vfc|;etables •7- to rel->ase the dried and ^annod and cur^.d products that can bo sent to our eoldiors and sailors and our alli.s.

POOR PEARS PROVOKE PUIIGEIIT POiiOLOGICAL PlilLiSES If you ha-e.^ver tri-;d to eat a Kieffer pear, as it tones from the tree, you v;ill appreciate this literary gem from the pen of U. P. Hedrick in "Pears of New York": "Pears are grovm to eat, but tliose of Kieffer are fit to eat only in culinary preparations, dire necessity alone tonpolling thei» consvimption uncooked." Of the LeConte, a pear of similar parentage, he says, "The fruits are rather poorer in quality than those of Kieffer, if that be possible for an edible fruit." (Scant praise, to say the least.) u8- TilE FOOD OUTLOOK FOR 1943 At a recent Outlook Conference in Yfeshington the food situation was summarized as follows: 1. Demands upon the nation's food from our armies and our allies are nov; tre- mendous. Still greater d^-jmands will develop when a second front is opened and starved civilian populations must be fed. There is no possibility of building a stock-pile for post-war needs. '"tTe will do vfell to keep something in the bottom of the barrel," 2. It is not expected that the 1943 commercial production can 'jqual the level of 1942. Every bit of food production possible must be secured in 1943. Tiiis p=;nding food shortage giv.3s tremendously added weight and meaning to home food production. 3. Possibilities for increased production lie largely with the small farrier, the part-time farmer, and the production of liome food supplies, both on farms and by other rural residents. In addition, food so raised will give families the opportunity to secure better nutrition than they are likely to get through rationing. 4. It is expected that fo^d supplies made available for domestic use during the comin„ year v/ill be reduced tr) a level not higher than that of 1935-39 in order to release adlitionai. food for strategic purposes. The above facts were presented at a conference in Arnlierst on November 2. The iblloiving policy concerning home food production was drawn up and approved at this conference. 1.

Vfhat we need in the present emergency is a pruning program\'\hich will help to eliminate lov; grade apples at the source. Vfe can do much to bolster up the 1943 spray prograjn by (1) cutting out every other diagonal row where trees are beginning to crowd, and (2) by a light tliirjaing of branches on the permanent trees. Labor for spraying next summer nay be more scarce than we nov; find it for pruning. Vie cannot afford to omit pruning entirely even under v/artime conditions. The kind of pruning very much needed in most bearing apple orchards may be started in December and continued through the winter, whenever v/eather permits. Let's use e'/ery suitable day between now and spring in thinning out those vreak, drooping branches and in pruning "at the ground level" the crowding fillers and other trees of unwanted varieties. The cold v/inter of 1933-34 caused severe damage to apple trees pruned heavily in December, 1933. This experience prompts the recommendation that we delay until late winter or early spring any heavy pruning which certain trees may require. But such trees are less common than the trees v/hich need only a light pruning. Dead and broken branches as well as shaded and submerged branches, may be removed any time during the viin- ter. By spreading the pruning job over a 4-month period instead of trying to do it all in March, v/e vdll help to increase the percentage of U. S. No. 1 apples. Anything below that grade is of doubtful value. Issued by the Extension S'-irvice, Vrillard A.

Thirty- five apple growers from 7 towns took part in the program. Offerings ranged from 50 to 2000 bushels. That 4-H boys and girls in Massachusetts produced over 3,000,000 pounds of vegetables, and canned 150,000 jars of fruits and vegetables in 1942? Five thousandvrorked on farms of parents or neighbors, 20QD aided in getting the v/in- ter fuel supply and 2,200 helped keep farm machinery in good condition. That chopped apples provide a partial substitute for silage in feeding dairy cov;s? Yilien corn silage is worth ^6 per ton, apples have a feeding value amounting to about 03.18 per ton. That apple pomace, fresh from the cider press, averages about 21^ dry matter compared to 20^o dry matter in silage from v/ell matured corn? It con- tains about 1/3 as much digestible protein as corn silage and is slightly lov;er in digestible nutrients. That there are about 252,000 spray rigs on commercial fruit farms in the United States? Many are high pressure outfits suitable for fighting fires. These sprayers, widely scattered in rural areas, offer an opportunity for the fruit grovrerto serve himself, his neighbors and his country on the home front. That a dozen Indiana apple grov;ers earned gold medals this season by producing apple crops grading from 90 to 99^^ U.S. No. 1? Three others re- ceived silver medals for crops scoring slightly under 90Jo U.S. No. 1. That there has been a gradual increase in the deer population in Massa- chusetts during the past 30 years. Records of deer killed during the hunting season are available since 1910. The largest number reported in any one year was 3,067 in 1940. In 1941 unfavorable weather during the hunting season re- duced the number to 1773. That, of the above ground parts of a fruit tree, the lower part of the trunk is latest in maturing its tissues for \vinter? A tree tends to mature from the top dovm. And if grovrth is prolonged too late, as for example v/hen poultry manure is applied in September, frost cracks in the bark of the trunk are likely to appear as soon as the temperature begins to hover around zero. That military and Lend-Lease needs for food v;ill be half again as great in 1943 as they were in 1942, and that they v/ill take about one-fifth of nur total food production? This v/ill mean one-fourth of our meat, one- third of our lard, one-third of our eggs, and one-half of our canned vegetables. The demand vrill be greater than our ability to produce. Certain crops v/ill need to be curtailed in order that others of a more vital nature may be ex- panded. FOOD PRODUCTION IN MSSACHUSETTS I.IUST BE INCREASED.

This curtailment applies not only to manufactured products but to supplies and repair parts with a fev^ exceptions, such as farm machinery. Warnings relative to scarcities of consumers' goods were sounded over a year ago and many heeded, laying in essential supplies, and putting their machinery and equipment in good order.

Harrington FAWl IvIACHiriERY REPAIR PROGRAIvI Ever;^ farmer knows that care is necessary to prolong the life of farm machinery. In past years there was a tendency on the part of some to buy a nev; piece of equipment, turning in the old one while still in good condition as part payment. Farm machinery v.'as cheap and the supply plentiful. This practice was therefore considered both sound and economical as the farmer always had a modern and dependable machine with a minimum of cash outlay for repairs and maintenance. This practice, current on many farms, is no longer possible, since vory fev/ new machines will be manufactured during vmr years. Other groups of farmers kept their machinery longer periods of time and depended upon local blacksmiths., machine shops or garages to make the necessary repairs and replacements. These practices were common and the results achieved were i:iost satisfactory as more skilled and other services as virelding v;ere available. Unfortunately, many of these services are now lacking or may be lack- ing in the future. In many cases it will behoove a farmer to look after his ovm servicing in his own shop. Last v/inter farmers were urged to "order parts early." The purpose of this was to enable manufacturers to plan their year's work in such a vmy that parts could be manufactured and supplied to dealers without delay. The results were most satisfactory. One large manufacturer of farm machinery said this program had resulted in an even demand throughout the year. This for the first time in the firm's history. V/ith the heavy repair orders for 1942 such a condition v.'ould not have been attained had not the farmers done their part. For the most part, farmers suffered little delay in receiving repair parts during 1942. It is again recommended that farmers order parts as early as possible. Many dealers in farm machinery having re- pair shops are in excellent position to service farm machines regardless of make. They usually do this best during the v/inter as this is often their slack season. The following program for the year 1942-1943 is suggested: (1) Make «. season-end checkup. (2) Order necessary parts. (3) Store machinery properly, (4) Hake necessary repairs this v/inter, (5) Prepare for 1943 season, (6) Op- -4- erate machinery carefully. (7) Make adjustments fes needed. Note: The 1943 Farm Equipment Limitation Order fixing the amount of farm machinery that can be manufactured betv;een November 11, 1942 and October _ 31, 1943, drastically affects the ability of the farm machinery companies to supply their customers. The Y/ar Production Board issued the above order on October 20, 1942. It limits production to not more than 20 per cent of the 1940 output. A large part of these goods will be produced by the smaller manufacturers. The larger companies undoubtedly viill stop production com- pletely on the majority of farm machines heretofore manufactured. They will, however, be permitted to continue making a few machines but only on a severe- ly curtailed basis. __Vj-. c. Harrington OVEKIAULING TliE SPRAYER One of the large manufacturers of spraying equipment urges growers to do an extra thorough job of overhauling the sprayer this winter. The follow- ing Vifartime advice is based on years of experiencei General. (1) Thoroughly clean entire machine. (2) Use oil and grease to protect' exposed parts subject to rusting. (3) Repaint if needed. The well cared for machine usually looks well cared for. Pump. (1) Inspect plunger packing and porcelain cylinder v/alls. Re- place if necessary. (2) Inspect all valves, clean thoroughly and replace parts only if absolutely necessary. Inspect valve gaskets. (5) Check condition of gears and gear alignment. Loose bearings v;ill cause rapid \/ear on gears. (4) Check wrist pins and other points for general wear and looseness. (5) En- closed puraps may require nevj oil seals and packing around plunger rods. (6) Put nev/ oil in enclosed pumps and run pump aften-^ard a few minutes to get coating of oil over all inside parts. Pressure Regulator. (1) Inspect condition of diaphragm rubber or hy- draulic leathe'r"cup. (2) Inspect valve ball and seat directly above stem. This is the most important valve in the pump. (3) Be sure and have good pack- ing around top of stem. Keep this packing tight. (4) Carefully adjust stem in accordance with instruction book. Drive Parts. (1) Gear drive - Adjust gears to mesh properly. (2) ChaTrr~driv© - Remove chain and clean in kerosene, re-oil thoroughly before replacing. Check aligniaent of sprockets. Adjust chain tension. (3) V-belt drive - Keep belts clean and tight. They must not slip. (4) Power take off universal s - Extreme vear may indicate poor hook-up or care- less operation when turning. Grease the sliding square shaft. Engine. (l) Check compression and determine if necessary to grin.d valves and overhaul pistons. (2) Check bearings for looseness. (3) Clean and adjust spark plugs. (4) Clean outside of radiator. A clogged radiator cannot cool the engine. (5) Magneto - Take to nearest official service sta- tion if necessary. -5- Suction to Pump. (1) Clean strainer screen. (2) Inspect suction hose, iTniust not leak air. (5) Check pipe connections. Tank. (1) Steel tank - If inside is in ^^ood condition, do not disturb. If shov:s*Tust pits, clean and coat Vfith heavj'' oil or light grease. (2) Vfood tank - Hoops uay require tightening but be careful and loosen as may be neces- sary when tank sv/ells in usage next spring. (3) Agitator - Llay require over- hauling - Use v/aterpump grease in agitator bearings. Truck and Frame. (1) Tighten bolts which may have loosened. (2) Have any brealcs"or~c'raclcs' in frame repaired by welding, (3) Inspect v/heel bearings and pack v;ith grease. (4) See that hitch is in good condition. Discharge Equipment. (1) Hose should be removed and stored away from heat and"ri"gKt". (2 j Spray *C-un s - Probably need repairing, (3) Potato Nozzles - Remove, clean and keep stored in oil. FARI.'I PRICING PREVENTS H. C. L. (From the Nov. 14 issue of The Tovm Crier) "Ceiling prices, inflation control, - these are things v/hich are appear- ing in the nev/spapers today. The Town Crier brings you a boiled down explana- tion of the purposes back of the v/hole program to control high cost of living, Mijiutemen and Rural War Action committee members might find this information useful when talking to their neighbors. "Present v;ar commitments now amount to between tv;o and three hundred billion dollars. If present prices were allowed to double you would double the cost of the war and all of us would pay that cost. That must be avoided, "Fresh fruits and vegetables, (other than potatoes, onions and citrus fruits) and fresh fish are the only important food products not nov/ controlled. These are very seasonal and hence it is difficult to set price ceilings which would be satisfactory. The Office of Price Administration and the United States Department of Agriculture recognize the program must be flexible to adjust for various factors such as geographic location, tj^e of farming, etc. In the fu- ture the ad:ninistration will think more and more in terms of farm parity in- come rather than farm parity prices. Future adjustments will be made accord- ingly. Some of these will no doubt take longer than we in the states think they should, "One advantage to this program is that prices frozen in advance will mean tliat farmers can plan ahead on farm production. Dairy and poultry farmers can be assured that the OPA and the USDA will fight to the last ditch to keep feed prices at present levels. To do otherwise would threaten a breakdown of the anti-inflation program. "Last but not least, if a group of farmers representing a certain type of farming believe they are entitled to price adjustments, they should contact the USDA through the county and state v/ar boards. The Department of Agricul- ture will consider revision." -6- A ^i"ARTIi.IE PROGRAM FOR FARI-ffiRS The first and most important job of farmers is to produce as much food as possible. The production of food is as important as the production of planes, guns and other war equipment. In order to produce the greatest amount of food it is necessary for every farmer to develop and maintain an efficient farm business. Costs of production have increased substantially partly because of higher prices and partly because larger inventories of feed and supplies must be maintained in order to avoid delay at critical periods. Conditions are favorable now for enlarging a small farm business to an efficient size if labor is available and the increase can be financed safely. It is unv;ise to borrow money to enlarge farms beyond a size necessary for reasonable efficiency. The second job of farmers is to get their debts in shape by reducing them to a safe basis. This is good for both the farmer and the Nation. In- come paid for debts does not compete for goods and equipment and therefore does not contribute to inflation. The third job of farmers is to invest in VJ'ar Bonds to help the Nation and to build financial reserves. Many farmers even if they are heavily in debt v;ill want to buy some V^'ar Bonds because they feel that they v;ould be giving direct financial aid to their country. However, in order that they may continue to produce food, farmers who are heavily in debt should use the greater part of any increased income to reduce their debts to a conservative basis so that they can stand lower prices and any adversity which nay come. Farmers viho are out of debt can invest at once all of their available income above operating and living expenses in V/ar Bonds. Farmers v;ho have xaoderate debts or v/ho have reduced their financial obligations to a safe basis should invest in Y/ar Bonds to the limit of their available net incomes. Unnecessary expenses should be postponed until after the war has been v/on. During this war period the production of farm machinery, household equipment and many other supplies v/ill be greatly reduced because of the increased need of steel and other material for war purposes. A part of the money v;hich farmers receive for their products pays for the wearing out of all types of farm equipment. This money v;ould automatically be used to re- place automobiles and farm equipment or to repair buildings and fences in peacetime. Such money should now be Invested in Vv'ar Bonds as a depreciation reserve v/hich will be available for replacement after the v/ar. By investing the cost of the desired equipment or improvements in 1/ar Bonds, it v;ill be possible to purchase them later when they are again available. After debts have been reduced to a safe basis, it is safer and better for most farmers to build an adequate financial reserve through investment inj \Tar Bonds than to apply all available income on debts. If all income is ap- plied on debts it will probably be necessary to borrow again in order to buy farm machinery or other equipment v/hen it again becomes available. V/ar bonds are the best form of finajicial reserve ever offered to Massachusetts fanners. They are promises to pay, of the strongest Government in the World. Bonds are available in three different series and in different denominations. Most farmers will prefer to invest in the series "E" bonds which are available at ^IS^^S, $37.50, 4i75.00, $375.00, and ^750. These bonds are not transferable but v/ill be repaid to the owner or his heirs if needed at any time after sixty days from date of issue. If left for one year or more, interest v;ill be received in addition and if they are left to maturity, in 10 ;rears the ovmer will j^et back v4 for every ^5 invested. War bonds can be bought at most post offices and banks. --Rov E. Moser gOIITROLLED ATI.IOSPIIERE STORAGE On September 25 the special controlled atmosphere storage at II.S.C. v;as filled and sealed up. This practically air-tight room with 300 bushels of apples, mostly Mcintosh, v^ill be kept closed during the storage season. Ti'e plan to open this room next Llay or June. This method of storage operation is not nev/. It was first v;orked out in some detail by English investigators and, more recently, considerable grower attention has been focused on it as a result of the experiments carried out at Cornell University. These experiments shov/ed that controlled stmos- phere storage may be especially suited to extended storage of Liclntosh. Previous to this year, we have experienced some difficulties in testing this system of storage. Our trouble has been due largely'' to a failure to get the room "gas-tight," because of small leaks in the sheet metal lining around the special door or in the "washer." Through normal respiration, the apples reduce the oxygen level in a tight room and raise the level of carbon dioxide - much the same as people. But apples caji remain alive with remarkably little available oxygen in the atmosphere - as little as 1 to 2 per cent (air contains 21 per cent). The carbon dioxide builds up as the oxygen in the air is utilized. Too much car- bon dioxide is harmful to apples, so the concentration of this gas is con- trolled. The atmosphere of the room is forced through a "washer," containing a solution of sodium hydroxide which chemically removes the carbon dioxide (an apparatus for testing the amounts of this gas and oxygen in the room is, of course, necessary). Hence, the original oxygen is gradually used up, the accumulating carbon dioxide is periodij.ally removed, and finally the desired gas content of the room is attained - around Z% oxygen, b% carbon dioxide and 9o^j nitrogen. The low oxygen level as well as the presence of considerable carbon dioxide slov; do\^m the respiration and hence the ripening rate of the apples even though a 40° F. temperature is maintained. The apple s"'""" live slowly" and hence their storage life is lengthened. At 40° F., furthennore, quality should be improved. Our storage is operating successfully at the present time and results this season should throw considerable light on the practicability of this method of storage for Massachusetts I.lclntosh. However, for several reasons including the present shortage of some essential items, any building program for controlled atmosphere storages is out for the duration of the Virar. Several of these storages have been operated in New York State with considerable success, — Lav/rence Southv^ick SQI.IE V/IIYS OF I.IAGITESIUI'J DEFICIEITCY There are at least five reasons for the widespread magnesium deficiency shovdng up in Massachusetts orchards. (1) Llany orchards have been planted on aoils naturally low in magnesium, asfbr example, soils of the I.Ierrimac series. R. VJ. Donaldson reports magnesium to be Lov: to Very Lovr in 50.3^o of the 2033 soil sam- ples tested in the past three years; 21% showed a Medium content of magnesium while only 22.T,'^ were Medium High to Very High. (2) Erosion and leaching have further removed magnesium from the soil. (3) Many bearing orchards have nov; reached such a stage of development that the roots have exploited the soil more or less completely. (4) Little agricultural lime has been applied in orchards and much of what has been applied has been high calcium and not high magnesium lime. (5) Our spray and dust programs involving heavy applications of sulfur hare made our orchard soils more acid. There is some evidence that magnesium is more likely to be deficient in a very acid soil.
