Evaluation of Imidacloprid 6%+ Lambda cyhalothrin 4% SL Against Sucking Pests of Cotton

Two field experiments were conducted to evaluate the efficacy of imidacloprid 6%+ lambda cyhalothrin 4% SL against sucking insects viz., aphid Aphis gossypii Glover, leafhopper Amrasca biguttula biguttula (Ishida), thrips Thrips tabaci L. and whitefly Bemisia tabaci (Gennadius) on cotton during kharif, 2018-19 and 2019-20 at the Agricultural Research Station, Dharwad farm, UAS, Dharwad, Karnataka. Results showed that the higher dose of imidacloprid 6%+ lambda cyhalothrin 4%SL @ 500 ml ha-1 resulted in 89.02, 88.52, 91.91 and 90.17% reduction of aphids, thrips, leafhoppers and whitefly, respectively in first season and 93.03, 87.15, 97.01 and 89.65% in second season compared to the untreated check. It was on par with its lower dose @ 450 ml ha-1. There was no significant difference in the counts of grubs and adults of coccinellids and number of chrysopids. Thus, imidacloprid 6%+ lambda cyhalothrin 4% SL could be used for the management of sucking pests without any effect on non-target insects.
