Two applications were used against Helicoverpa armigera (Hubner) and the results revealed that the highest incremental per cent reduction of larvae was recorded in the plot treated with T6 Indoxacarb 14.5% SC (48.47) which was at par with T4 Spinosad 45%SC (42.24), T2 Emamectin benzoate 5%SG (33.7), T3 Chlorantranilprole 18.5%SC (33.17), T1 Flubendamide 480 %SC (30.89), T7 Fipronil 5%SC (29.42) and T5 Neem oil 4% (25.06) is found to be least affective than all other treatments. Cost benefit ratio were found highest in Indoxacarb 14.5% SC (1:12.6), followed by Spinosad (1:11.7), Emamectin benzoate 5% SG (1:9.85), Chlorantranilprole 18.5%SC (1:9.82) Flubendiamide 480 SC (1:8.7), Fipronil 5% SC (1:6.7), Neem oil 4℅ EC (1:7.9) as compared to control T0 (1:5.06).
