Abstract: An experimentation was done to observe the efficacy of some insecticides and economics against shoot and fruit borer, Earias vittella (Fabricius) of okra during kharif season 2015 at the Vegetable research farm, JNKVV, Jabalpur, Madhya Pradesh. The insecticidal treatments emamectin benzoate 5% SG @ 12 g a.i./ha was found to be most effective as it recorded minimum fruit damage (12.36%) followed by emamectin benzoate 5% SG @ 10 g a.i./ha (15.36%) and imidacloprid 17.8% SL @ 35.6 g a.i./ha (19.66%), difenthiuron 50 WP @ 300 g a.i./ha (23.22%). The next effective treatments were imidacloprid 17.8% SL @ 17.8 g a.i./ ha (26.80%) and thiamethoxam 25% WG @ 25 g a.i./ha (27.72%) both were found to be at par with each other, while NSKE 5% g a.i./ha (35.08%) was found least effective among all the insecticidal treatments. The highest net return was obtained from emamectin benzoate 5% SG @ 12 g a.i./ ha and the maximum cost benefit ratio was obtained in imidacloprid 17.8% SL @ 35.6 g a.i./ha (1:32.33) due to lower cost than others.
