College of Agriculture, Anand Agriculture University, Anand during rabi 2021-22 to study the bio-efficacy of different biopesticides against aphid, Aphis craccivora Koch infesting Indian bean. Different ten treatments were evaluated. Indian bean (Gujarat Papdi -1) crop was grown. Among the evaluated biopesticides, Neem Seen Kernel Extract (NSKE) 5%, neem oil 0.5% and Lecanicillium lecanii 1% WP emerged out as the best biopesticidal treatments. Whereas, aqueous bidi tobacco dust extract, Garlic bulb extract (GBE) 5%, B. bassiana 1% WP were mediocre in their effectiveness against aphid population. The less effective treatments were Ginger rhizome extract (GRE) 5%, aakdo, C. procera 10% and cow urine 10%.
