Abstract
The study was conducted to determine efficacy of insecticides against Thrips, Megalurothrips sjostedti Trybom on cowpea grown at field experiments were conducted at Breeder Seed Production Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar 2014.The most effective treatment for the control of thrips Megalurothrips sjostedti Trybom was seed treatment with fipronil @ 3 ml/kg + spray with fipronil @ 5 ml/lt with maximum reduction (70.06%) in the thrips population of cowpea while lowest effective treatment for the control of thrips Megalurothrips sjostedti Trybom was seed treatment with imidacloprid 17.8SL @ 10ml/kg + spray with monocrotophos 36SL @ 2ml/lt with minimum reduction (16.02%) in the thrips, Megalurothrips sjostedti Trybom population of cowpea crop.
