Abstract
Effect of certain insecticides in rice ecosystem was studied for their role in resurgence of brown plant hopper (BPH) during kharif and rabi 2016-17. Among fourteen insecticides evaluated, seven insecticides viz., chlorpyriphos, profenophos, deltamethrin, cypermethrin, bifenthrin, lambdacyhalothrin and imidacloprid were observed to significantly increase the incidence of BPH over untreated check after 1st, 2nd and 3rdsprays consistently and resulted in induced resurgence. Acephate, monocrotophos, cartap hydrochloride, fipronil, chlorantraniliprole, buprofezin and pymetrozine effectively controlled the BPH and did not induce resurgence. Thus, these can be used judiciously, with periodic monitoring of resistance and resurgence.
