During kharif 2019, the efficacy of combined insecticides against the fall army worm Spodoptera frugiperda (J E Smith) in maize was assessed. Chlorantraniliprole 9.3%+ lambdacyhalothrin 4.6%ZC was the most effective. Fipronil 4% + acetamiprid 4%SC was less effective. All treatments were effective in increasing the yield- chlorantraniliprole 9.3% + lambdacyhalothrin 4.6 %ZC gave maximum grain yield (40.70 q/ ha) while maximum benefit cost ratio was obtained with thiamethoxam 12.6 + lambdacyhalothrin 9.5%ZC (1:28.33).
