Bio-efficacy of newer insecticides and neem derivatives against major insect pests of soybean

Abstract

A field experiment was laid out in Randomized Block Design with twelve treatments replicated thrice to study the bio efficacy of newer insecticides and neem derivatives against major pests of soybean at Instructional Farm, Rajasthan College of Agriculture, Udaipur (Rajasthan) during kharif season of year 2014 and 2015. The treatments consisted as Chlorantraniliprole 18.5 SC, Emamectin benzoate 5 SG, Flubendiamide 39.35 SC, Novaluron 10 EC, Spinosad 45 SC, Triazophos 40 EC, Neem leaf extract 10%, Neem cake extract 10%, NSKE 5%, Azadirachtin 10000 ppm, NSKE 5% + B. bassiana and Control. It was revealed that spraying of Triazophos 40 [email protected]/lit recorded significantly maximum reduction of jassids and white fly population at 3,7 and 14 days respectively followed by emamectin benzoate 5 SG at first as well as second spraying during both the years. In case of semilooper and Tobacco caterpillar spraying of Spinosad 45 SC @ 0.4ml/lit recorded significantly maximum reduction of population followed by chlorantraniliprole 18.5 EC at 3, 7 and 14 days respectively during both the years at first and second spraying.
