A field experiment was carried out at Central Research Farm (CRF), SHUATS, Uttar Pradesh, India, during the Kharif season (autumn reap) for a total of three months, from mid-July to mid-October, 2022. The seven treatments—Indoxacarb 14.5% SC (T1), Deltamethrin 2.8% EC (T2), Karanjin oil (T3), Metarhizium anisopliae 1*108 CFU (T4), Neem oil 5% (T5), Emamectin benzoate 5% SG (T6), Spinosad 45% SC (T7), and control plot (T8)—were each replicated thrice in the experiment. Data regarding Earias vittella infection percentage of the first and second sprays showed that all treatments were much better than the control. The lowest percent infestation of Earias vittella was recorded by Deltamethrin 2.8% EC (17.745% & 13.608%), which was followed by Emamectin benzoate 5% SG (18.837% & 15.777%), Spinosad 45% SC (19.610% & 16.565%), Indoxacarb 14.5% SC (20.092% & 18.147%), Neem oil 5% (20.602% & 18.900%), Karanjin oil 5% (22.080% & 21.639%), Metarhizium anisopliae 1*10⁸ CFU (22.710% & 21.837%). Deltamethrin 2.8% EC produced the largest output, 129 q/ha, as well as the highest B:C ratio (1:5.45). It was followed by Emamectin benzoate 5% SG (1:5.31), Spinosad 45% SC (1:5.19), Indoxacarb 14.5% SC (1:4.93), Neem oil 5% (1:4.76), Karanjin oil 5% (1:4.64), and Metarhizium anisopliae 1*10⁸CFU (1:4.58) when compared to control plot (1:3.01) whose B:C ratio is very low.
