Popis:	Endosulfan, oxydemetonmethyl, and endrin applied in sprays at 1 lb per acre to Russet Burbank potatoes were equally effective in the control of the green peach aphid, Myzus persicae (Sulzer). The incidence of leaf roll in growing plants was reduced significantly when spray applications were continued until mid-June. Also 4 applications ending in late June reduced net necrosis in the tubers and chronic leaf roll in stocks replanted the next season. Net necrosis was a less reliable index than chronic leaf roll for determining the effectiveness of insecticides in suppressing leaf roll. Chronic leaf roll developed in 96, 30, and 18% of plants grown from tubers that contained net necrosis, other discolorations, and no discolorations, respectively.
