C*4.mcMter Fanning, Saturday, January 1, 2000 Courier Bees Help Reduce Costly Fungi, Impact On Environment WOOSTER, Ohio - Forget the tractor, the sprayer and the labor. An Ohio State University researcher has found that bees are ready and able to deliver bio controls to strawberry plants. Not only do the courier bees help protect berries from the fungi Botrytis, fruit yields increased too, said Joe Kovach, director of the Integrated Pest Management program at Ohio State University. Kovach will discuss the use of bees for Botrytis fruit rot control at the joint meeting of the North American Farmers’ Direct Marketing Conference and the Ohio Fruit and Vegetable Growers Congress, Feb. 10-12, in Cincinnati. Botrytis is a gray mold or fungus that causes strawberries to rot. Infection occurs in the flowers, but the mold doesn’t multiply until the fruits mature. In wet years, Botrytis can damage close to 100 percent of an untreated crop, while during dry years the damage is mini mal, Kovach said. A fungal bio control, Trichoderma harzianum, controls the fungi. A biocontrol uses a living organ ism, instead of a synthetic chem ical, to control a pest. For exam ple, a beneficial insect would feed on unwanted insects. Current integrated pest man agement recommendations call for one to two biocontrol applica tions at bloom, depending on the strawberry variety, bloom length and weather conditions. But Kovach wanted to mini mize the impact from spraying one step further. “We knew bees were able to DeMuth Silage Spreaders Manufactured with Amish craftmanshlp In Lancaster County Demuth’s unique roll forming process produces wear resistant curved comers Leola, PA Schiller Park, IL Waterloo, Ontario Tel: (717) 656-4295 (847) 671 -3400 (519) 884-2980 Fax: (717) 656-3289 (847) 671 -3404 (519) 884-8824 VISIT US AT WWW.DEMUTH.COM Oun #605-606 s4t 'KecfAtoHC o p
