Abstract: An experiment was directed to observe the efficacy of some insecticides against shoot and fruit borer of okra during kharif season of 2014 at the Entomological experimental field, JNKVV Jabalpur (M.P.). The treatments emamectin benzoate 5% SG @ 12 g a.i./ha. recorded higher fruit yield (58.00 q/ha) as compared to control (23.69 q/ha). followed by emamectin benzoate 5% SG @ 10 g a.i./ha (52.00 q/ha) and triazophos 40% EC @ 400 g a.i./ha (50.00 q/ha) both were found to at par each other. Whereas other insecticide Thiamethoxam 25% WG @ 50 g a.i./ha (41.53 q/ha), thiamethoxam 25% WG @ 25 g a.i./ha (38.70 q/ha) and imidacloprid 17.8% SL @ 21.36 g a.i./ha (36.65 q/ha) was also shows better results. The highest net return was obtained from emamectin benzoate 5% SG @ 12 g a.i./ha but the cost benefit ratio was lowest (1:9.83). And the maximum cost benefit ratio was obtained in triazophos 40% EC @ 400 g a.i./ha (1:15.60) due to lower cost than others.
