50 AUGUST 2015 Good Fruit Grower A U.S. Department of Agriculture entomologist is exploring low-cost adju- vants, such as yeasts, that could increase the efficacy of codling moth controls. Dr. Alan Knight, at the Yakima Agricultural Research Laboratory in Washington, and colleague Dr. Peter Witzgall, chemical ecologist at the Swedish University of Agricultural Sciences in Alnarp, found that the cod- ling moth granulosis virus was more effective when combined with yeast and sugar. The virus is applied to orchards as a biological control for codling moth, a serious pest of apple and pear. When ingested, the virus infects the gut of the larva. As the infection advances over the course of about a week to ten days, the larva stops feeding, turns black, and dies. The virus is specific to codling moth and harmless to beneficial insects and humans. Most commercial formulations of the virus have not provided consistent control, scientists report. It degrades rapidly in ultraviolet light and high temperatures and usually does not kill Results rise with ADJUVANTS Bread yeast shows potential for improving pesticide performance. by Geraldine Warner are planted with the most popular seedling, semi-dwarf and dwarf varieties: Our Fields Prunus avium/P. mahaleb M.106/M.7/M.26/B.118 Prunus EMLA Colt OHxF Series Geneva® Series M.9 Clones We also grow a great selection of rootstock varieties for apple, peach, pear and plum including: Like our rootstock, our service will grow on you.
