Abstract: The field trial conducted at SHUATS, Prayagraj during Rabi 2022-23. Eight treatments were evaluated against Helicoverpa armigera i.e., T1 Flubendiamide 48% SC, T2 Emamectin benzoate 5%SG, T3 NSKE 5%, T4 Spinosad 45% SC, T5 Neem oil 2%, T6 Chlorantraniliprole 18.5% SC, T7 Neem leaf extract 10% and T0 untreated control. Results revealed that, among different treatments lowest population of chickpea pod borer was recorded in T6 Chlorantraniliprole 18.5% SC (1.58). T4 Spinosad 45SC (1.72) is found to be next best treatment followed by, T1 Flubendiamide 48% SC (1.93), T2 Emamectin benzoate 5% SG (2.04), T3 NSKE 5% (2.33), T5 Neem oil @ 2% (2.43), whereas T7 Neem leaf extract 10% (2.48) found to be least effective against this pest. The highest yield was recorded in T6 Chlorantraniliprole 18.5% SC (22.13q/ha) followed by T1 Flubendiamide 48% SC (20.63q/ha), T4 Spinosad 45% SC (20.24q/ha), T2 Emamectin benzoate 5% SG (19.47q/ha), T5 Neem oil 2% (18.32q/ha), T3 Neem Seed Kernel Extract (17.82q/ha), T7 Neem leaf extract 10 % (16.74q/ha) and T0 Control (11.43q/ha).among all the treatments studied, the best and most economical treatment was T6 Chlorantraniliprole 18.5% SC (1: 2.76) followed by T1 Flubendiamide 48% SC (1: 2.75), T4 Spinosad 45% SC (1:2.61), T2 Emamectin benzoate 5% SG (19.47q/ha and1:2.59), T5 Neem oil 2% (1:2.48), T3 Neem Seed Kernel Extract (1:2.46) T7 Neem leaf extract 10 % (1:2.27) and Control (1:1.67).
