Thrips and Lygus Control from Seed Applied Insecticides

Brian H. Marsh and Robert B. Hutmacher


ABSTRACT

Early season insect pests may develop into a serious problem under less than ideal cotton growing weather conditions. Seed applied insecticides can be effective in controlling these early season pests. Temik (aldicarb), Gaucho (imidacloprid) and Adage (thiamethoxam) were applied with the seed to evaluate their control of thrips (Frankliniella occidentalis) and lygus (Lygus hesperus) at two locations. Early season insect pressure was very light. Lower thrips counts and less leaf damage were observed for all three treatments versus the untreated check. The insecticide treatments were all equally effective. The negligible early season insect damage did not have any long-term effect as cotton lint yields were not significantly different.
