Abstract: The field trial was conducted at SHUATS, Prayagraj, during Rabi-2022-23. Experiment was laid out in RBD (Randomized Block Design) with eight treatments replicated three evaluated against Helicoverpa armigera i.e., T1 Novaluran 10% EC, T2 Emamectin benzoate 5% SG, T3 Chlorantraniliprole 18.5% SC, T4 Beauveria bassiana 1×108CFU, T5 Neem oil 4%, T6 Spinosad 45% SC, T7 Nisco Sixer Plus and T8 untreated Control. Were tested to compare the efficacy against Helicoverpa armigera and their influences on yield of Tomato. The best and most economical treatment is Chlorantraniliprole 18.5% SC (260q/ha) followed by Spinosad 45% SC (245q/ha), Emamectin benzoate 5% SG (225q/ha), Nisco Sixer Plus (200q/ha) Novaluran 10% EC (185q/ha), Neem oil 4% (163q/ha) Beauveria basiana 1×108 CFU (149q/ha) and as compared to control T8 (80q/ha). After calculating the benefit cost ratio of different treatments highest B:C ratio of different treatments was observed Chlorantraniliprole 18.5% SC (1:6.02) followed by Spinosad 45% SC (1:5.65), Emamectin benzoate 5%SG (1:5.30), Nisco Sixer Plus (1:4.72), Novaluran 10% EC (1:4.32), Neem oil 4% (1:3.83), Beauveria basiana 1×108CFU (1:3.53), as compared to untreated control T8 (1:1.96) having the lowest B:C ratio.
