A field investigation was undertaken to determine the efficacy of certain botanicals against seed weevil, Apion amplum (Faust) (Apionidae: Coleoptera) in green gram during 2008_09 under organic ecosystem. Total of ten botanicals were tested at 1%, 2%, 5% and 10% concentrations. All the botanicals were significantly better in managing seed weevil and increased grain yield. NSKE @ 5% was found to be best in reducing weevils (2.83, 1.89/plants, respectively) and lesser pod (31.33%) and seed damage (30.92%) followed by Vitex negundo @ 5% and Acorus calamus 5%. Treatment with NSKE @ 5% recorded maximum grain yield (247.33 kg/ha). Under laboratory conditions also NSKE @ 5% resulted in 100% mortality compared to other treatments after 5 days of treatment.
