Evaluation and Economics of Selected Insecticides and Bio-pesticides against Fruit Infestation of Helicoverpa armigera (Hubner) on Tomato

The field trial was conducted in Central Research Farm (CRF) at SHUATS, Prayagraj, during Kharif-2021-22. experiment laid out RBD (Randomized Block Design) and replicated thrice with seven treatments. Viz., T1 Indoxacarb 14.5%EC, T2 Flubendiamide 39.5%SC, T3 Emamectin benzoate 5%SG, T4 Bacillus thuringiensis 5% WP, T5 Spinosad 45% SC, T6 Neem oil 4%, T7 Chlorantraniliprole 18.5%SC, (T8) untreated Control tested to compare the percent fruit infestation against Helicoverpa armigera their influences on yield of Tomato. lowest best economical treatment were recorded 45 SC followed by 14.5% 18.5% SG, 39.5% thuringenesis WP 4% as compared control T8. highest obtained 45SC (260q/ha) 14.5%SC (245q/ha), (225q/ha), 5%SG (200q/ha) (185q/ha), (163q/ha) (149q/ha) T8 (80q/ha). After calculating benefit-cost ratio different treatments B: C observed for (1:8.8) (1:8.3), Chlorantraniliprole18.5% (1:7.6), (1:7.2), SG (1:6.8), (1:6.3), (1:5.6), (1:2.8) having ratio.
