Abstract
Granular formulations of phorate, disulfoton, propoxur Dasanit® (O,O-diethyl O-[P- (methylsulfinyl) phenyl] phos-phorothioate), and aldicarb applied as systemic insecticides by 3 methods, in the seed furrow preplanting, broadcast on the soil preplanting, or sidedressed into the soil around established bean plants, were only partially effective in controlling Lygus elisus Van Duzee and L. hesperus Knight; the onion thrips, Thrips tabaci Lindeman; the pea aphid, Acyrthosiphon pisum (Harris); the green peach aphid, Myzus persicae (Sulzer); the two-spotted spider mite, Tetranychus urticae Koch; and several leafhopper species. Application of dimethoate as an emulsifiable spray to bean foliage was no more effective in controlling lygus bugs and the two-spotted spider mites than the application of systemic insecticides. Disulfoton, propoxur, and Dasanit applied as a preplanting broadcast at a rate of 3 lb/acre increased bean yield 100-200 lb/acre, but the yields were not significantly better than those in the check plots. Aldicarb reduced yields compared with the check when it was applied as a systemic at a rate of 3 lb/acre by any method. However no phytotoxicity was visible in the foliage or in the bean stand.
