Among nine insecticide molecules tested for their bio-efficacy against major pod borers the foliar sprays of chlorantraniliprole 18.5 SC @ 0.15 ml/l was found to be most effective against all the pod borers. The efficacy of chlorantraniliprole 18.5 SC was on par with spinosad @ 0.15 ml/l and emamectin benzoate @ 0.2 g/l. Similarly, the least per cent pod damage was observed in Chlorantraniliprole 18.5 SC treatment (12.57 %) followed by Emamectin benzoate 5 SG (15.83 %) and Spinosad 45 SC (17.60 %) which were statistically on par with each other. The results on the cost economics of pod borer complex management revealed that, among the treatments the pod yield was maximum (27.45 q/ha) in Chlorantraniliprole 18.5 SC followed by Spinosad 45 SC (25.48 q/ha) and Emamectin benzoate 5 SG (24.80 q/ha) which were statistically on par with each other. Accordingly, the highest net profit (Rs.63969 /ha) was documented in chlorantraniliprole 18.5 SC. This was followed by spinosad 45 SC (Rs.58019 /ha), emamectin benzoate 5 SG (Rs.56807/ha). The highest cost benefit ratio was obtained in chlorantraniliprole 18.5 SC (1: 3.48). This was followed by emamectin benzoate 5 SG (1: 3.23), spinosad 45 SC (1: 3.15).
