Abstract
Most plum curculios hibernate in the debris within 50 feet of the edge of the woods surrounding the peach orchards. Burning this debris during the winter killed many curculios, but apparently not enough to permit any reduction in the amt. of spraying that was necessary. Benzene hexachloride gave good curculio control when used at 4 lb. (6% gamma isomer) per 100 gal. and 3 to 4 gal. of spray per tree. One 25-acre block was cleaned up so thoroughly that the 1-month-before-harvest spray was not necessary. Benzene hexachloride caused an off-flavor in canned peaches but not in the fresh fruit (5 applications, last application one week before harvest). Chlorinated camphene showed promise in controlling plum curculio but wettable sulfur had to be used as a safener with this material. Cryolite, lead arsenate, and hexaethyl tetraphosphate caused injury to the peach trees, leaves, and fruit.
