Abstract: The present investigation entitled Efficacy of selected chemicals and Bio -pesticides against gram pod borer (Helicoverpa armigera) on chickpea under field condition was conducted during rabi 2023-24 using Chick pea in a plot size of (2 m × 1 m) at a spacing (30cm × 10cm) in Randomized block Design where 8 treatments were replicated thrice with a recommended package of practices excluding plant protection. The treatments taken for research along with Spinosad 45% SC (T₁), Bacillus thuringenesis (T₂), Neem oil (T₃), Imidacloprid 18.5% SC (T₄), Nisco sixer plus (T₅), Chlorantraniliprole 18.5% SC (T₆), Ha NPV (T₇) and Untreated plot (T₈). Two applications of eight treatments against Helicoverpa armigera were used. Among all the treatments lowest larval population of pod borer was recorded in T₆ Chlorantraniliprole 18.5% SC (0.35) followed by T₁ Spinosad 45% SC (0.41), T₄ Imidacloprid 18.5% SC (0.48), T₅ Nisco sixer plus (0.53), T₃ Azadirachtin (0.61), T₂ Bacillus thuringiensis (0.68) and T₇ Ha npv (0.75) found the highest population of pod borer and is population significantly superior over the control (3.42). When the benefit cost ratio was worked out, interesting results was achieved. Among the treatment studied the best and most economical treatment was Chlorantraniliprole 18.5% SC (1:2.54) followed by T₁ Spinosad 45% SC (1:2.3), T₄ Imidacloprid 18.5% SC (1;2.43), T₅ Nisco sixer plus (1:2.08), T₃ Azadirachtin (1:1.92), T₂ Bacillus thuringiensis (1:1.58) and T₇ Ha npv (1:1.05) as compared to control T₈ (1:0.9).
