Abstract: A field trail was conducted at Cental Research Farm, SHUATS, Naini, Prayagraj, U.P. during kharif season of 2021 in Randomised Block Design with eight treatments were evaluated against, Spodoptera frugiperda i.e., Spinetoram 11.7%SC @0.9ml/lit, Chlorantraniliprole 18.5%SC @0.4ml/lit, Flubendiamide 39.35%SC @0.24ml/lit, Emamectin benzoate 5%SG @0.4g/lit, Neem oil 2% @5mi/lit, NPV @0.5ml/lit, Novaluron 10%EC @1ml/lit and control plot. First and second spray were carried with 15 days interval, the results revealed that, among the different treatments Spinetoram 11.7%SC, (4.93) was most effective treatment over the control followed by Chlorantraniliprole 18.5%SC (6.24), Flubendiamide 39.35% SC (6.42), Emamectin benzoate 5%SG (6.90), Novaluron 10%EC (8.13), NPV (8.28) and Neem oil 2% (8.37). Spinetoram 11.7%SC showing a highest yield of (41.10q/ha) against the control yielding up to (22.31q/ha) at the same time among the treatments studied, the best and most economical treatment was Spinetoram 11.7%SC (1:1.79), followed by Chlorantraniliprole 18.5%SC (1:1.78), Flubendiamide 39.35%SC (1:1.77), Emamectin benzoate 5%SG (1:1.74), Novaluron 10%EC (1:1.68), NPV (1:1.60) and Neem oil 2% (1:1.44) when compared to control plot (1:1.25).
