40 OCTOBER 2015 GOOD FRUIT GROWER USDA develops low-chill peach A new peach variety with extremely low chilling requirements has been developed by the U.S. Department of Agriculture. The new variety, Gulfsnow, requires only 400 hours of chilling to flower and set fruit and should help growers in the southeastern lower coastal plain produce a more reliable supply of early-summer peaches, according to the USDA's Agricultural Research Service. By compari- son, June Gold, a variety commonly grown in that area, requires 650 hours of chilling. Gulfsnow is a round, fresh-market peach with 50 to 60 percent red blush over a cream background. The flesh is creamy-white and firm. It ripens in early June in Attapulgus, Georgia, about 10 days after Gulfcrimson. Dr. Thomas Beckman, horticulturist at the USDA's Southeastern Fruit and Tree Nut Research Laboratory in Byron, Georgia, developed Gulfsnow to overcome the chilling problem, which has become worse in recent years as winter temperatures have trended warmer and chilling hours have declined. Treat for voles in the fall L iphaTech, manufacturer of the rodenticide Rozol (chlorophacinone), recommends monitoring for orchard voles in the summer and treating twice in the fall or once in the fall and once in the spring. Voles can girdle the trunk and roots, disrupting the flow of nutrients. They can also create air pockets near tree roots, causing stunting and root disease. The most severe vole damage is during the winter. Two Rozol treatments reduce the chances of voles surviving, breed- ing, and feeding under snow cover. Placing T pipe bait stations on the borders helps maintain an uninterrupted supply of bait and reduces migration into the orchard. For more information go to MAP slider bag launched V iew Fresh, a modified atmosphere packaging (MAP) system for fresh fruit, is now available as a slider bag. The View Fresh Spectrum-Slider bag closes using a slider fastener, which eliminates the need for a sealing machine, increasing operator efficiency and lowering labor costs. Removing the sealing machines means less potential downtime due to broken equipment and less risk of worker injury, according to Brenda Thomas, president of Orchard View Farms in The Dalles, Oregon, which owns the View Fresh brand. View Fresh has been used for fresh cherries since 1992 and is now available for kiwis, blueberries, and plums. It is popular with Asian importers.

The polymer lure con- tains a selective chemical attractant that catches flies earlier than other attrac- tants. Each lure lasts for at least four to six weeks. The lure was developed in cooperation with scientists at the U.S. Department of Agriculture, Oregon State University, the Oregon State Department of Agriculture, and Washington State University. For more information call Scentry at (800) 735-5323. Control pests with heat A groThermal Systems, based in Walnut Creek, California, is marketing a thermaculture machine, which can be used to apply heat to vineyards with the goal of increasing yields, controlling pests and diseases, and improving crop quality. The propane-powered machine is towed through the vineyard at seven-day intervals. The machine is being used at Shane McKibben's 240- acre vineyard, Les Collines, in Walla Walla, Washington. According to AgroThermal, McKibben reports success controlling early-season pests, such as thrips, mites, and powdery mildew. He also saved time that would have been spent mixing chemical sprays and filling up the tank. Go to for more information. GOOD STUFF A selection of the latest products and services for tree fruit and grape growers Register for cider conference T he United States Association of Cider Makers will hold its annual conference February 2-5, 2016, at the Hilton Portland and Executive Tower in Portland, Oregon. As part of CiderCon, an orchard production work- shop will be held February 3 from 8 a.m. to 1 p.m. to provide the latest information to commercial apple farmers interested in growing cider apples for fermen- tation. The workshop will cover site selection, root- stocks, varieties, training systems, irrigation, weed control, pest management, economics, and cost of establishment and production. The workshop cost is $65 and includes lunch. Mike Beck, owner of Uncle John's Cider Mill in St. Johns, Michigan, and president of the association, said growth in the hard cider industry has been explo- sive in the last decade, capturing a 1 percent share of the beer market and having a potential of five times that.
