Bioefficacy of Certain Chemicals and Biopesticides against Pod Borer [Helicoverpa armigera (Hubner)] on Chickpea (Cicer arietinum L.)

The research work was undertaken at Central Research Farm (CRF) Sam Higginbottom University of Agriculture Technology and Sciences SHUATS, Naini, Prayagraj during rabi season in 2022 -23 consists eight treatments including control viz, T1- NSKE 5% @ , T2- Neem Oil 5%, T3-Bacillus thuringiensis@ 5mg/ml, T4-Beauveria bassiana@ 1×1010 conidia/ml, T5-Profenofos 40% + Cypermethrin 4% EC, T6 – Spinosad 45 SC, T7- Emamectin benzoate SG T0- untreated Randomized Block Design (RBD) with three replications. mean larval population chickpea pod borer Helicoverpa armigera after two spraying revealed that @1 gm/lit found the most efficient among all (2.32 larvae/5 plants), highest cost benefit ratio (1:3.87) marketable yield (29.16q/ha), followed by SC 0.5 ml/lit a (2.60), (1:3.27 26.66 q/ha), Profenofos 40%+Cypermethrin EC 3 population, (2.77, 1:3.42 25.83 Bacillus thuringiensis 5mg/ml (3.01, 1:2.93 22.5 Beauveria bassiana conidia/ml yield(3.24, 1:2.83 21.25 oil yield(3.49, 1:2.25), yield(3.77, 1:1.75 13.33 q/ha). is least effective plot T0 (5.84, 1:1.54 11
