Evaluation of insecticides for the management of shoot and fruit borer Earias vittella (Fab.) infesting okra

Abstract

The present field experiment was conducted during kharif season-2014 at the Research Farm, Department of Entomology, JNKVV, College of Agriculture, Rewa to study the efficacy of insecticides against shoot and fruit borer, Earias vittella (F.) on okra. All the treatments were found to be superior over the untreated control. The results revealed that two sprays of Chlorantraniliprole 18.5% SC @ 30 g a.i./ha was found to be most effective in managing the fruit borer infestation on okra followed by Thiamethoxam 25 WG @ 30 g a.i./ha. Among different insecticidal treatments, maximum per cent fruit infestation on number and weight basis was recorded in two sprays of DDVP 76% EC @190 g a.i./ha. The highest marketable fruit yield of okra (73.26q/ha) was also obtained from two sprays of Chlorantraniliprole 18.5% SC at 15 days interval @ 30 g a.i./ha.
