Abstract:
In the trial conducted to test the comparative toxic effect of insecticides against coccinellid predators, associated with sucking insect pests of mothbean at S.K.N. College of Agriculture, Jobner (Raj.) during kharifi 2005, Profenophos + cypermethrin (0.04%), lambda-cyhalothrin (0.005%) and dimethoate (0.03%) were found highly toxic to coccinellid predators. Thiamethoxam (0.025%), imidacloprid (0.005%) and novaluron (0.02%) were ranked in middle order of toxicity while, the plant products viz; azadirachtin (5 ml/l), NKSE (5.0%) and KSE (5.0%) proved least toxic
