Field studies were conducted on the efficacy of bio-pesticides against gram pod borer, (Helicoverpa armigera L.) at experimental field, Organic Research farm Karguwan Ji, Department of Entomology, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (Uttar Pradesh) during Rabi Season of 2022-2023. Different bio-pesticides viz.: Neem oil, Verticillium lecanii, Bacillus thuringiensis (5% WP), Metarrhizim anisoplae, Garlic extract, NSKE 0.5%, Karanj oil 0.5%, Beauveria bassiana. Experimental results revealed that the plant treated with bio-pesticides registered a significant difference of gram pod borer Helicoverpa armigera L. over the treatment of untreated control. Among them, the treatment of Bacillus thuringiensis (8.30 larvae/5 plant) was found in significantly more effective against the pest as compared to other bio-pesticides Neem oil, Verticillium lecanii, Bacillus thuringiensis, Metarrhizim anisoplae, Garlic extract, NSKE, Karanj oil, Beauveria bassiana. were found moderately effective and proved significantly superior over and of Bacillus thuringiensis, Beauveria bassiana and Neem oil proved significantly less effective among the bio-pesticides evaluated against gram pod borer Helicoverpa armigera L.
