The field investigation was carried out in the Prayagraj district of Uttar Pradesh. The experiment was conducted in rabi 2022 at Central Research Farm (CRF), SHUATS, Naini, Prayagraj district. The field was laid in RBD with three replication and eight treatments viz., Beauveria bassiana (2×10⁸ CFU/gram) (2 ml/liter), Metarhizium anisopliae (2×10⁸ CFU/gram) (2 g/liter), Bacillus thuringiensis (1×10⁹CFU/ml) (2 ml/liter), Ha NPV (1×10⁹ POB’s/ml)  (1 ml/liter), Azadirachtin 0.3EC (5 ml/liter), Spinosad 45% SC (0.5 ml/liter), Neem seed kernel extract 5% (5 ml/liter), and untreated controlled plot to check the efficacy of biopesticides against pod borer, on chickpea. The result on the efficacy of treatments the least larval population was recorded in Spinosad 45% SC (0.96) followed by Ha NPV (1.20), Bacillus thuringiensis (1×10⁹ CFU/ml) (1.84), Beauveria bassiana (2×10⁸ CFU/gram) (1.91), Metarhizium anisopliae (2×10⁸ CFU/gram) (2.02), Azadirachtin 0.3EC (2.22), Neem seed kernel extract 5% (2.48) and the highest larval population of pod borer was found in control treatment (4.02). In another parameter higher yield and cost benefit ratio was recorded in Spinosad 45% SC (20.33 q/ha) (1:2.84), followed by Ha NPV (1×10⁹ POB’s/ml) (18.60 q/ha) (1:2.59), Bacillus thuringiensis (1×10⁹ CFU/ml) (17.65 q/ha) (1:2.46), Beauveria bassiana  (2×10⁸ CFU/gram) (15.68 q/ha) (1:2.19), Metarhizium anisopliae (2×10⁸ CFU/gram) (14.58 q/ha) (1:2.03), Azadirachtin 0.3% EC (13.81 q/ha) (1:1.92) and Neem seed kernel extract 5% (13.58 q/ha) (1:1.89) as compared to control (10.83 q/ha) (1:1.54).
