Relative toxicity of noval insecticides against leaf eating caterpillar, Spodoptera litura Fabricius infesting soybean

Abstract

A field experiment on evaluation of relative toxicity of eight different insecticides (Indoxacarb, flubendiamide, chlorantraniliprole, chlorfenapyr, novaluron, emamectin benzoate, beta-cyfluthrin, quinalphos) against leaf eating catterpillar of soybean was conducted at Agricultural Research Station, College of Agriculture, Anand Agricultural University, Jabugam. The results revealed that less numbers of Spodoptera litura (5.90 larvae/ 10 plants) were found in chlorantraniliprole whereas, minimum (9.86) larval population of S. litura also noticed in plots treated with emamectin benzoate (9.86) followed indoxacarb (13.91) and flubendiamide (14.52). The pest was suppressed significantly in plots sprayed with these insecticides over control.
