Abstract

Present study was conducted at the CCS Haryana Agricultural University, Hisar during kharif 2019 and 2020. Insecticides viz., chlorantraniliprole 18.5 SC, emamectin benzoate 5SG, lambda-cyhalothrin 5EC, pyridalyl 10EC, cypermethrin 25EC and quinalphos 25EC were applied thrice at recommended dose of 25, 6.75, 15, 50, 37 and 200 g a.i. ha -1 , respectively for the management of Earias spp. in okra. The effect of these on the incidence of Amrasca biguttula biguttula (Ishida) and Bemisia tabaci (Genn.) was also assessed. Results revealed that application of quinalphos caused maximum reduction (54%) of A. biguttula biguttula followed by chlorantraniliprole (43.40%) and lambdacyhalothrin (42.80%). In case of B. tabaci, application of chlorantraniliprole caused maximum reduction (44.74%) followed by lambdacyhalothrin (33.33%) and emamectin benzoate (28.16%).
