Two applications of seven insecticides were used against Helicoverpa armigera and the result revealed that Chlorantraniliprole 18.5% SC had the lowest fruit infestation with 1.55 and 1.24 followed by Flubendiamide 39.35% SC (1.68 and 1.33), Emamectin benzoate 5% SG (1.84 and 1.53), Indoxacarb 14.5% SC (1.95 and 1.61), Spinosad 45% SC (2.04 and 1.82), Profenofos 50% EC (2.17 and 1.93) and Imidacloprid 17.8% SL (2.24 and 2.08) respectively as compare to control (water spray) 3.19 and 4.64. Cost benefit ratio were found highest in Chlorantraniliprole with 1:12.09 followed by Flubendiamide 39.35% SC (1:11.27), Emamectin benzoate 5% SG (1:10.70), Indoxacarb 14.5% SC (1:9.84), Spinosad 45% SC (1:9.01), Profenofos 50% EC (1:9.21), Imidacloprid 17.8% SL (1:6.85) and Control (1:6.13).
