Abstract
Seven new molecule insecticides viz., Deltamethrin, Lambda-cyhalothrin, Emamectin benzoate, Indoxacarb, Bifenthrin, Rynaxypr and Flubendiamide were bio-assayed against okra shoot and fruit borer (Earias vittella) to study the residual toxicity on Okra at College of Agriculture, Raipur during the Rabi applied season(2014-15 and 2015-16).. On the basis of average LT50 values, the order of toxicity was Emamectin Benzoate > Indoxacarb > Lambda-Cyhalothrin > Rynaxypr > Flubendiamide > Deltamethrin > Bifenthrin against okra shoot and fruit borer.
