A field experiment was conducted during rabi 2022 at Central Research Farm, SHUATS (Sam Higginbottom University of Agriculture, Technology and Sciences), Prayagraj, Uttar Pradesh (India) using Randomized Block Design with eight treatments and replicated thrice. The Result showed that the effects of Insecticides against Spodoptera frugiperda, among the different treatments, Lowest larval population of maize fall army worm was recorded in Emamectin benzoate 5SG (1.178), Lambda cyhalothrin 5EC (1.311) is found to be the next best treatment following Spinosad 45SC (1.445) and Flubendiamide 49.35SC (1.567) is found to be the next effective treatment, Thiomethoxam 12.6 + Lambda cyhalothrin 9.5ZC (1.700) is found to be the next effective treatment followed by Chlorantraniliprole 18.5SC (1.833) , Beauveria bassiana 5% WP (2.134) is found to be least effective but comparatively superior over the control, The yields among the different treatments were significant. The highest yield was recorded in Emamectin benzoate 5SG (42.5 q/ha) with highest cost benefit ratio of (1:2.42) followed by Lambda cyhalothrin 5EC (40.5 q/ha and 1:2.3), Spinosad 45SC (37.8 q/ha and 1:1.83), Flubendiamide 49.35SC (31.3 q/ha and 1:1.79), Thiomethoxam 12.6 + Lambda cyhalothrin 9.5ZC (29.2 q/ha and 1:1.68), Chlorantraniliprole 18.5SC (26.8 q/ha and 1:1.36), Beauveria bassiana 5% WP (22.4 q/ha and 1:1.24) as compared to Control (15 q/ha and 1:1.091).
