Q By Margaret J. Pratt, Extension Educator, Agriculture, Hiiisborougti County r^— =-L embers of the New R M I Hampshire Department of ■Iff I I Agriculture, Division of I ■ I I Pesticide Control, and IimbbbJ UNH Cooperative Exten- sion met recently to discuss the possi- bility of instituting a partial credit system for recertification of Private Pesticide Applicators. Presently New Hampshire has this type of system in place for Commercial Applicators, and it seems to be working well. Currently, Private Applicators recertify by attending a single meeting held only once every five years by Cooperative Extension. The last recertification meeting for Plant Growers was held in the fall of 1988. This one meeting meets all the requirements necessary for recertification. Instituting a partial credit system would mean that individu- als would be able to accumulate credits over five year periods by attending a series of meetings. There are both advantages and disad- vantages associated with a partial credit system for Private Applicators. Some of the advantages and disadvantages are outlined below. One advantage is that Private Appli- cators would be able to choose between a variety of meetings where credit could be obtained, rather than attend one meeting every five years. This would allow growers the fiexibility of attend- ing meetings at their convenience. Meetings would most likely be spon- sored by Cooperative Extension, or industry and professional organizations such as trade and producer groups. By attending several meetings over a five year period, more information would be available to applicators to keep them abreast of trends and changes in the laws. Recertification meetings covering current issues would almost certainly offer better quality information and education. Also, meetings that are presently held and attended by many growers (such as twilight meetings) could be considered for recertification credit provided they meet the require- ments of the Division. Keep in mind that an application for recertification credit would have to be submitted 45 days before the scheduled meeting. The following factors might be con- sidered disadvantages under a partial credit system. Because a Private Appli- cator would have to accumulate credits from several meetings he or she will have to travel more often. In addition, some meetings offering credit might be held out of state. Private Applicators would also have to take responsibility for finding out about meetings which offer recertification credits. Notice of such meetings is published in the Weekly Marketing Bulletin; however, reminders are generally not sent out. Professional organizations would need to keep members posted by publishing notices in their newsletters. Applicators would be issued a Certifi- cate of Attendance for each recertifica- tion meeting attended. They would be responsible for obtaining the required number of credits and for holding onto Certificates of Attendance until the fifth year of the recertification cycle. If an applicator loses his or her Certificates of Attendance, or does not accumulate enough credits, he or she would have to take the examination to recertify. A partial credit system would place more responsibility on applicators to seek out meetings and to maintain records of at- tendance. The Pesticide Conuol Division would not do this. Partial recertification is under discus- sion as a result of questions and comments from growers. Many of the states surrounding New Hampshire operate under a partial credit system. As a result, at regional meetings growers from other states frequently are eligible for pesticide credits while New Hampshire growers are not. Some growers have indicated thai they would prefer to operate under a partial credit system. To assist the committee in their delib- erations. Cooperative Extension and the Pesticide Control Board would like to get input from Private Applicators about their feelings concerning a partial credit system. If you have problems with the idea, they would like to know what those problems are. If you favor such a system, they would like to know that as well. It would be appreciated if you would direct your comments to cither Murray McKay at 271-3550 or Dr. Stanley Swier at 862-1 159. You may call or submit written comments. Written comments should be sent to the Division of Pesticide Control, Caller Box 2042, Concord, NH 03302-2042. The decision on this issue will be made on feedback from the industry, so each comment counts. WAa/6sa/& J/io 35 Pomsnd St., East Rochester, NH 03867 • (603) 332-7388 • 332-0127 • 332-2 \.

In much the same way, the NHPGA Board of Directors has been looking at the needs of the membership and seeking ways to better meet those needs. During the past year, the Board has grown from four directors to six with the additions of Bruce Holmes and Alan Eves. Kalhy Gamester, who has worked hard as a board member and co-editor of The Plantsman, has resigned. Jennifer Gould has taken her place. (Currendy only one Board position still remains unfilled.) Lastly, Dr. Charlie Williams, after serving for many years as the editor of The Plantsman, has stepped down, and we look forward to working with our new editor. Bob Parker. We would like to continue to encour- age active participation at all levels. Our display at the Spring Garden Show in Manchester was an example of what enthusiastic support can accomplish, and we thank Alan Eves for his effort. As the New Hampshire Plant Growers' Association continues to meet your changing needs, it is my hope that, through the Board's leadership and with active input from the membership, we can more effectively represent the di- verse interests of New Hampshire's plant growers and offer educational, marketing, and meeting opportunities to better promote our plants and services throughout the state and beyond. I look forward to our summer meeting at The Greenery in Ossipee on August 1, and we welcome all com- ments on the changes we are making.'^ Welcome To Our New Members: Bruce Borden, RR 2, Box 650, Wyman Road,Keene, NH 0343 1 Wendy Clark, 23 Dauntless Lane, Plaistow.NH 03865 D.S.

American I I Flower Bulb Wholesalers I I recently at their annual ^-■iHMaJ meeting. Bulb sales have seen a greater than average growth over the past five years. Most of it is due to packaging and promotion of what was once a com- modity product. Companies like Van Bloem's arc leading the way with aggressive innovation and smart marketing. The fall they have an aggressive flyer program that can greatly help retailers increase sales. At the February NorCal Trade show the "classic" example of packaging, promotion and product innovation was being introduced by the Clyde Robin Seed Company - A professional golf course green for the homeowner. The kit comes complete with Pencross Creeping Bentgrass seed, Hagpole, prac- tice cup and complete blueprints and insffuctions. Retailing at $44.95, it is the ideal gift for "golf-gardeners."* Time IVIagazine Study Reinforces Customer Service I Z L ncreased levels of customer I I service will be critical for I I retailers in the future - not I I o"'y in dealing with custom- '^■i^^J ers but also in the products they are offering. A recent study by Time Magazine has revealed interesting facts that can help retailers better serve their custom- ers' needs. •The amount of leisure time enjoyed by the average American has shrunk 37% since 1973. •During the same period, the work week (including commuting) has increased from 41 to nearly 47 hours. •People are taking shorter vacations, often just four day weekends. •Although leisure time is declining, standards on quality are rising. To the garden center operator this means customers want professional looking results with less effort. Retail- ers offering products and ideas that save the customer time will be re- warded with repeat business and more cash register rings.'* Professional Plant Growers Scholarship - - J| endy Clark, a May '90 « n vl graduate of the Thompson lfl#l School, was recently pre- W W [ senled with a Professional ^^■■B Plant Growers Scholarship.

Behind the buildings are new greenhouses and piles of loam and rows of potted nursery stock. There's a lot going on. It's surprising to see so much happening in what seems a fairly isolated place. "In 1987," manager Bruce Holmes says, "It was a twenty acre woodlot." Developer (and ^^ former Red Sox owner) Buddy Leroux began construction in late 1987. Holmes started work in January 1988. Today it's an impressive garden center and one that's still expanding. The salesroom opens onto two 28x80 Nexus Teton houses connected to create an additional 58x80 feet of retail space. The sides are standard - eight mil polycarbon- ate point-fastened on to the frame; the roof is eight mil exolite - a rare instance of this material being used on an arched roof. The installation was technically tricky because the exohte is placed in the glazing system in a way that allows it remain flexible - it's actually floating so that it can expand or contract with the weather. So far, it's worked fine. This greenhouse area is used for retail business and for growing as 1^1^ well. Along with the pool surrounded by tropical floor plants shipped up from Florida are benches of ge- raniums, begonias, impa- tiens, and dusty miller. Just outside this com- plex are two Criterion houses (14x48 and 25x48) and seven hoop houses (one 28x48, six 14x48) from Ed Persons, the proprietor of ^^^ Ledgewood Farms and a ^^^ local greenhouse manufac- turer. These are filled with an assortment of annuals and vegetables. The annuals are standard - marigolds, snapdragons... The uniqueness is in the number of varie- ties — they carry "Rocket" snaps, for ex- ample, and forty types of petunias, and taller plants that can be grown for use as cut flowers. Behind these is the newest addition to the complex, a new propagation house. A 42x96 Rough Brothers lech-lite house, it is an all aluminum structure with polycar- 7/7 1987.Jt was a twenty acre woodlot...' GREENHOUSE AND NURSERY STOCK RETAIIBE bonate walls and an acrylic roof. It has all-natural venting, with double runner automatic roof vents and manual side vents. It has ro-flo moveable benches and under bench heating using an Alcoa hot water system. Although still not finished, it's filled with four inch gerani- ums. Behind the greenhouse is about five acres of potted nursery stock. The plants are bought in spring, potted up, wintered over - the evergreens are stored in the hoop houses; the deciduous material is laid under microfoam, then covered in plastic - and sold the following year. Holmes feels the extra year in the pots allows the development of a solid root system that insures the quality of the product Obviously, with five acres of mate- rial, there is a broad selection. This is particularly true of the deciduous mate- rial - there's an unusually wide variety of flowering crabs, for example. And the AREA numbers of varieties available will con- tinue to grow. Another specialty seems to be devel- oping in the area of geraniums. Currently twenty types of standards and fifteen of ivies are being grown. Although the busi- ness is primarily retail. Holmes hopes that, as production continues to expand, a wholesale business will develop. He sees this happening as people realize what The Greenery has to offer. In August, an open acre beside the greenhouses will be filled with potted mums. In 1988, 3500 were grown; last year, 7000; this year 15,000 plants — all potted in Classic 600's — will be grown. Holmes feels the larger pot produces a bigger plant of higher quality. And the business continues to ex- pand. This spring, a retail outlet in down- town Wolfboro will open for its second season. And other expansion, perhaps a florist shop added to the retail center in Ossipee, is being talked about. As a way of introducing themselves to other members of the profession, the Greenery will host the Plant Growers' summer meeting on August fu-st. Holmes wants people "just to realize we're here" and to see The Greenery as "a major source of quality plant material in New Hampshire". Along with the tours of The Green- ery, there will be a tailgate trade fair (Bruce is hoping for between thirty and forty vendors) and the New Hampshire Agricultural Agents Association will put on one of their famous chicken barbeques. Visits to Spider Web Gardens in Tuftonboro are also planned. Established in 1938, it is one of the older garden centers in New Hampshire. It sells field- grown annuals, nursery stock, and peren- nials. Its specialties include iris, daylilies, hosta, and peonies. Over forty varieties of peonies are in the half-acre devoted to this plant's production. With nine green- houses, twenty employees, and eight acres under cultivation, there should be plenty to see here as well. And there are door prizes - among them a weekend for two in Waterville Valley and tickets to a Red Sox game - so the day should be fun, a good chance to talk with friends, look over new products and see two (one of the newest and one of the oldest) of the Lakes Region's finest greenhouse and nursery operations.'* "In 1988, 3,500 plants were grown; last year, 7,000; this year 15,000 plants, all potted in Classic 600's will be planted" PROPAGATION HOUSE "The Power of Suggestion" Wise Old Marketing Tool a By Una Sawtette I ^ k| t's not newIBut it's easy! I I And it worics! Yet many I I still don't take full I I I advantage of it! What? ^■^■■i The mighty "Power of Suggestion!" In a marketplace where the majority of families have two workers, increased disposable income, their own homes, and less shopping time, the Power of Suggestion works better than ever. Show customers a great idea and they will buy! The gardening industry is supplying consumers with instant grati- fication and instant beauty! That's what they're looking for ! Show them you have what they need! On the retail front, customers can be encouraged to buy more through creative techniques such as showing new and beautiful arrangements of plant material in patio planters, live demon- strations of containerized gardens, planting instructions, and design ideas using new varieties or outstanding color schemes. Sounds straightforward, right? But how many retailers put 100 varieties of perennials out on the tables without sug- gestions? Suggestions can range from the simplest form of signage with suggested uses or a poster with pictures of plants in bloom and their characteris- tics, to a more creative approach such as perennial show gardens utilizing the plants being sold. Add a sign in the promotional garden, "These Plants for Sale In Our Greenhouse Area." Perhaps even more creative is to team up with local landscapers who would like to plant and maintain some gardens in exchange for advertising and referrals. Suggestive use promotions need to be placed as close as possible to the products being promoted. A suggestive design for a planter will be much more effective if placed next to the plants that are used rather than in a different location where the customer has to make the connection on his own. Tell the customer what you want him to do and make it easy! Wholesalers can and should utilize the Power of Suggestion as well. As a wholesaler you can ultimately increase your own sales by offering some marketing tools to your resale accounts. Offering point of purchase sales materials for the plants and other stock you sell is a widely needed customer service. Following are some ideas for the wholesaler to utilize: • All stock needs colored identifica- tion tags with brief descriptions and characteristics. This includes all hanging plants, house plants, annuals, perennials, and nursery. • Develop instructional sheets for planting and caring for annuals, perennials, and nursery stock. • Develop garden or planter design sheets utilizing the plants you sell. Customer should be able to get all the items needed to put the garden or planter together in one stop. Make it easy for people to buy! • Provide value-added products such as preplanted patio pots for quick pickup and instant gratification or mixed gardens such as herb gardens, low light gardens, or patio vegetable gardens. • Offer companion planting ideas for the customer. • Provide ideas to the retailer for design techniques. • Have special holiday preparations or design ideas. Nontraditional ideas are great. Customers are always looking for alternatives to the traditional gifts. • Provide off season fillers to the retailer with ideas for promoting their use such as indoor herb planters, hanging plants, or larger annual and perennial slock. These promotional ideas are an added service the wholesaler can offer the retailer. There are companies who specialize in some of these point of purchase materials. You may be able to obtain some of the items from these companies in addition to developing some of your own unique materials. By combining these suggestive techniques with your products you can enhance your sales and profits. This service may be the edge that sets you apart from the rest. And the Power of Suggestion sells! Remember, BE FIRST OR BE DIFFERENT. What do you have to offer that makes you unique? Utilizing the Power of Suggestion tool may be just the thing for you!

But did you know they want more? According to a nationwide study by Adweek's Market Week magazine and Warwicke, Baker and Fiore advertising agency, 93 percent of customers want more rest rooms and 49 percent are will- ing to pay extra for the convenience. The second most desired item (62 percent of these surveyed) was a place to sit down. Garden center owners may want to consider making the shopping experi- ence more pleasant by providing functional niceties. Extra seating in the outdoor selling yard or greenhouse can be incorporated in small display gardens that can increase the sale of plant material and garden benches. Clean and easy-to-find restrooms should be accessible to the handicapped. Putting yourself in your customer's place, wouldn't these amenities make your garden center a more pleasant place to shop?'ir (from Garden Center Newsletter, May- June. 1990) Lilies Usually, the lily is associated with specific occasions, like Easter or funer- als. But this long-time trend may be changing, reports the Flower Council of Holland. Extensive research in Holland has enabled the lily population to grow tremendously, allowing it to become a multi-purpose flower. Researchers attribute the growth of the lily population to an increased awareness of the flower's ornamental value and keeping quaUties. The increase in the varieties of Oriental and Asiatic Hybrids, including the Connecti- cut King, Enchantment, Laura Lee, and Furore, has also helped to expand the population. In 1970, Holland had only two acres devoted to the cultivation of lily bulbs. Today there are more than 6,100 acres, and the total supply of lilies to Dutch auctions rose to 236.5 million stems last year. Current lily research concentrates on resistance to disease and keeping quali- ties. Researchers are cross-fertilizing Asiatic lilies with Orientals in hopes of combining the best qualities of each. In the short term, this may not increase the quantity of lilies, but it should increase quality, says Holland's Flower Coun- cil.* (excerpted from SAF — Business News for the Floral Industry. April 1990) And in California... a New Whitefly An introduced pest, the ash whitefly, is causing serious problems in Southern California, and it is moving north. The pest host range includes many common landscape species. The ash whitefly (Siphoninus phil- lyreae) was first found in Van Nuys, California, in July, 1988. It spread rapidly and is now found in 12 Califor- nia counties. Entomologists believe it will eventually spread throughout the state. It has primarily infested ash and pear trees, but is known to attack apple, peach, apricot, and plum. Heavy infestations cause leaf wilt, early leaf drop, and smaller fruit. Pesticides have proved ineffective because the populations are large and widespread. A pesticide-treated tree is soon re-infested by whiteflies from other sources. It is not clear where this particular form of whitefly originated, according to Bob Obermire, Oregon Department of Agriculture Plant Division. "We don't know if this is a tropical form or not," he says. "If it is tropical, the chmate may keep it in check. If it comes from northern Europe, it could be a problem, particularly on Rosaceae species." Obermire said that the pest does not require plant material to move and may travel inside vehicles. This would make a quarantine very difficult to manage, he added. Pesticide treatment is used primarily on nursery stock shipments destined for non-infested areas. But none of the pesticides tested provided completely clean slock. And only a few kept the pest at moderate levels for seven days. California researchers are not recom- mending using pesticides on landscape materials. Mature landscape trees have withstood heavy infestations for two seasons without marked loss of vigor, despite some defoliation. Researchers are now working on introducing natural enemies of the ash whitefly. These include parasitoids, predators, and diseases. They appear to be a major controlling force in Europe, where this whitefly does not seem to reach pest status. Crop losses have oc- curred only in areas lacking effective natural enemies.lf (from Digger, April. 1990; Source: California Agriculture, Vol. 44, #1) And California Again.., The State of California may ban metallic or "foil" balloons, due to the power outages they have caused and to their potential life-threatening danger. During the first ten months of 1989, metallic balloons caused 593 power outages in California, according to the California Public Utilities Commission (CPUC). The outages disrupted power lines of 733,000 customers and cost power companies $444,52 1 . (The power disruption occurs as the metallic balloon makes direct contact with the power lines.) The CPUC has made three proposals to regulate the balloons to the California legislature. Two of these call for complete bans.'*' (from SAF — Business News for the Floral Industry, April 1990) 22 Supplying One Stop Shopping For AH Your Needs • Delivery Service Throughout New England • Fine Nursery Stock • Rhode Island Grown Sod delivered direct or picked up • Grade "A" used railroad ties • Pressure treated landscape ties • Bark mulch & screened loam • Wholesale Christmas trees, wreaths & supplies • Masonry supplies • Professional chemicals: Roundup, Surflan, Treflan, Balan & Team Distributors of: Permaloc aluminum edging.

Al- though named for the plant in which it was first found, tomato spotted wilt virus (TSWV) can infect an ex- tremely wide range of plants (New Guinea Impatiens, gloxinia, cycla- men, exacum) and a large number of weeds. Formerly the disease was a problem only in tropical and sub- tropical regions of the world. In more temperate regions, it occurred sporadically in greenhouses where the environmental conditions were favorable for growth and the insects that transmit (or vector) the virus. Thrips are the only known vectors of TSWV. Symptoms Due to the wide host range and the several strains of virus that exist, symptoms are variable and may resemble those caused by fungi. Symptoms may include irregular necrotic (dead) spots on leaves, discolored veins, black or purple stem streaks, falling of leaves or buds, stunting, irregular leaf shapes, black leaf spots, necrotic young leaves, and colored spots or stripes on petals. Black, brown, reddish, or yellowish concentric rings, although not always present, are virtually certain symp- toms of virus infections. In general, symptoms vary a great deal from crop to crop and infected plants may show no symptoms at all. Specific ex- amples will be given for four crops. Tomato Two or more of the following occur on the foliage: downward curling of leaves; leaf distortion; whole plant stunting and yellowing; bronze or purplish marking on leaves, including "thumbprints" or dots sur- rounded by rings (ringspots), or flecking; dark purplish stem streaks, tip or seedling dieback; or wilting. On green fruit, blotches or spots of pale green or white, or small bumps near the surface. On maturing fruit, yellow, orange, or green spots or blotches, vertical cracks, corky patches or lines, black spots, ring- spots, or lumps may be present. Severely affected plants may form no fruit at all, or the fruit may be very small and unmarketable. Diseased plants do not yield well. Impatiens Small dark purple ringspots often occur on leaves; flowers may also display ringspots, but here the rings are usually white. Dark streaks on stems or leaves, especially involving the mid-rib; leaf yellow- ing, leaf malformation; leaf drop; and stunting may occur. Plants infected while still young, or older plants severely affected may lose many leaves, look "leggy" and generally appear unthrifty. Cyclamen The most distinctive symptom of TSWV is the thumbprint-like yellow ringspots on leaves. Brown streaks, in addition to rings, may be present on petioles. Flowers are often mal- formed. Corms may be constricted into an elongated shape and, when cut, the vascular tissues of the corm appear as brown streaks. Plants stop growing, brown spots appear on leaves and leaf edges, and eventually plants wilt and die. The roots usually look fine until the plant is near death. It may take three months or longer from the time the plants were first in- fected for symptoms to appear, during which time the plants look perfectly healthy. Gloxinia Young plants will show symp- toms similar to certain fungal diseases. Symptoms may appear as stunting of new leaves or browning of the central or basal portion of the plant, followed by collapse and plant death.

In all host plants, symptom ex- pression will vary depending upon the age of the plant at the time of infection, environmental conditions (especially temperature), host variety or cultivar, and strain of the virus. Disease Cycle Tomato spotted wilt virus, in virtually all cases, is u-ansmiited by thrips. Thripsare tiny (l/16of an inch) winged insects that feed on plants by sucking sap from cells of leaves and flowers. Immature thrips acquire the virus when feeding on diseased plants; the insects then spread the virus as adults feeding on healthy plants. The virus multiplies within the plant and may exist throughout it, even though some parts of the plant may look perfectly healthy. TSWV survives the winter in infected plants, including those held over the winter in greenhouses, and in many species of weeds. These plants act as reservoirs of the virus from which it can spread in the spring by the feeding activities of the thrips. Disease Control in Greenhouses There are three primary methods of control: (1) sanitation, including weed control; (2) exclu- sion of the vector and diseased plants, and (3) insecticides to control thrips. Sanitation practiced dili- gently will prevent spread of the virus. Keep the greenhouse area free of weeds because they may harbor both thrips and the virus. Destroy plants known to be infected; do not use these plants for propaga- tion, even if some parts appear to be normal and healthy. Inspect incom- ing crops carefully for thrip infesta- FREEZE FRACTURE OF SOYBEAN LEAF ENLARGED 480 TIMES. tions or unusual symptoms. Accept only healthy, insect-free plants. Fine mesh screen (400 mesh) can be used on doors, air intakes, and screens to prevent thrips from entering houses from the outside. Monitoring thrips in the green- house using yellow sticky cards placed near vents and above crop level will allow detection of increas- ing thrip populations. Thrips are at- tracted to the yellow cards and be- come trapped on the sticky surface. Cards should be checked at least once a week. When the number of trapped thrips seems to be increasing, an in- secticidal spray may be warranted. A second application should be made four days after the first. Thrips, especially the Western Flower Thrips, have been found to de- velop populations resistant to certain insecticides that are used repeatedly, so it is important to rotate the class of insecticide used. For example, pyre- thoids, carbamates, chlorinated hydro- carbons, organophosphates, and soaps PHOTOGRAPH: JOHN KNOWLES should be used in rotation instead of constantly applying just one chemical class. Insecticides should be applied in the early morning, when thrips are most active and when the potential for plant toxicity reactions are mini- mized.
