Two applications of seven insecticides were used against Helicoverpa armigera. Results revealed that treatments T6-Lambda cyhalothrin 0.005% LE is most effective treatment with lowest Mean larval population of gram pod borer with (0.73) followed by T3-Emamectin Benzoate 5% SG (1.13), T7- Indoxacarb 14.5% SC (1.29), T5-Cypermethrin 25 EC (1.36), T4- Spinosad 45% SC (1.38), T1-NSKE 5% (1.45), T2-Neem oil 3% (1.66) as compare to T0-control (Water spray). Cost benefit ratio were found highest in T6-Lambda cyhalothrin 0.005% LE (1:4.5) followed by T3-Emamectin Benzoate 5% SG (1:4.5), T7- Indoxacarb 14.5% SC (1:4.0), T4- Spinosad 45% SC (1:4.0), T5-Cypermethrin 25 EC (1:3.8), T1-NSKE 5% (1:3.8), T2-Neem oil 3% (1:3.6) and control T0 (1:2.3).
