Abstract:

Seven insecticides were evaluated in 4 replicated field experiments on head lettuce in the Salinas and Pajaro Valleys of Central California for control of the green peach aphid, Myzus persicae (Sulzer), and the alfalfa looper, A utographa californica (Speyer). Insect populations encountered during- these experiments allowed evaluation of Imidan® (O,O-dimethyl phosphorodithioate S-ester with N- (mercaptomcthyl) phthalimide) and Agritox® (O-ethyl O-2,4,5-trichlorophenyl ethylphosphonothioate) against the alfalfa looper, and oxydemeton-methyl against the green peach aphid. Monitor® (O,S-dimethyl phosphoramidothioate), methomyl, phosalone, and Agrilox controlled the alfalfa looper at rates as low as 0.5 lb active ingredient (AI) per acre, but Imidan was less effective at this rate. Oxydemetonmethyl and Monitor at 0.5 lb/acre and methomyl at 0.75 lb were the most effective insecticides against the green peach aphid. Phosalone when compared at equal rates of 1 lb AI/acre to endosulfan as a standard resulted in similar control of both species.
