Abstract

Field experiment was conducted to evaluate the efficacy of some new insecticides with conventional insecticides for the control of mustard aphid, Lipaphis erysimi (Kalt.) and their effect on coccinellid population in rapeseed-mustard. All the treatments were found significantly effective in reducing the infestation of mustard aphid and increasing the yield compared with control. Maximum control of mustard aphid was obtained with the application of thiamethoxam 25% WDG @100 g/ha followed by imidacloprid 17.8% SL @ 150 ml/ha. Conventional insecticides were found less effective than newer insecticides for controlling mustard aphid. The newer insecticides which were found effective in controlling mustard aphid are also found safe to coccinellid population than conventional insecticides at all observational interval.
