The efficacy of ten insecticides and bioagents against sucking insect pests, viz., leaf hopper, Empoasca motti Pruthi; whitefly, Bemisia tabaci (Genn.) and aphid, Aphis craccivora Koch of cluster bean Cyamopsis tetragonoloba (Linn.) Taub. revealed that dimethoate (0.03%), imidacloprid (0.005%) and thiamethoxam (0.025%) proved to be the most effective. The acephate (0.037%), profenophos (0.05%) and ë- cyhalothrin (0.008%) were ranked in the middle order of effectiveness; whereas, novaluron (0.02%), diflubenzuron (0.05%), NSKE (5.0%) and Metarrhizium anisopliae (2 x10⁷ spores l⁻¹) were proved to be the least effective.
