Abstract:
Field trials were conducted during kharif season, 2016-17 with rice variety HUBR 10-9 to determine the bioefficacy of certain newer insecticides against Rice Gundhi Bug, Leptocorisa acuta (Thunberg). Results revealed that among all the insecticides sprayed pymetrozine@150g treated plot was observed to be best and the plots treated by this chemical gave a yield of 6.69 tons/ha, when we consider Rice Gundhi Bug as a sole pest in rice ecosystem. The overall treatments found in the order as pymetrozine@150g a.i.(5.82), pymetrozine 200g a.i.(6.29), Cartap Hydrochloride (7.08), Dinotefuran@150ga.i.(8.94), Dinotefuran@ 200g a.i.((9.07) and Thiocyclam hydrogen oxalate(9.89) Avg. no. of adult & nymph/5 sweep nets.
