In vivo toxicity of newer insecticides in comparison to conventional insecticides against Lipaphis erysimi (Kaltenbach)

Abstract

Field efficacy of newer insecticides in comparison to conventional insecticides against Lipaphis erysimi (Kalt.) was evaluated at Norman E. Borlaug Crop Research Center of G.B. Pant University of Agriculture and Technology, Pantnagar (India) during rabi season of 2016-17. Results revealed that the treatments of thiamethoxam 25 WG, imidacloprid 17.8, dimethoate 30 EC, oxy-demeton methyl 25 EC, acetamiprid 20 SP, acephate 75 SP and clothianidine 50 WDP proved to be effective against mustard aphid with higher seed yield of 21.69, 21.43, 20.69, 20.41, 20.24, 20.17 and 19.35 q/ha, respectively. The least effective treatment was fipronil 5 SC with lower seed yield of 16.62 q/ha.
