abstract
An investigation was carried out to study the relative Efficacy of some newer insecticides and biopesticides against jassid (Amrasca biguttula biguttula Ishida) infesting brinjal in randomized block design with these replications at Crop Research Center of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut during kharif 2017. Efficacy of different treatments viz imidacloprid 17.8 SL, buprofezin 25 SC, fipronil 5 SC, spinosad 45 SC, emamectin benzoate 5 SG, Bacillus thuringiensis, and neem oil 1500 ppm reveled that all the treatment were found significantly effective in reducing the population of jassid. The most effective treatment in reducing the population of jassid was imidacloprid 17.8 SL @ 100ml/ha followed by fipronil 5 SC @ 750 ml/ha. The Bacillus thuringiensis @ 1.0kg/ha was found less effective but it was significantly superior over control.
