Popis:	Dimethoate (2.67 lb AI/gal EC) was evaluated on heavily-infested backyard sweet cherry trees and in lightly infested commercial cherry orchards for control of Rhagoletis indifferens Curran. A single dilute application rates of 0.33 and 0.51 lb AI/100 gal 31–56 days pre-harvest gave excellent control during 1971–72 and 1974 field tests. Bioassay tests against adult western cherry fruit flies with several registered and nonregistered contact insecticides indicated dimethoate to be the most effective and persistent compound evaluated. Residues of dimethoate on cherries were collected 2 years and were within currently registered tolerances for this material on pome fruits. Phytotoxic effects including marginal foliage necrosis and minor defoliation in 1974 field tests were noted but are not considered serious.
