Groundnut (Arachis hypogaea L.) family (Fabaceae) is a legume crop grown for its edible seeds. The plant is damaged by various insect pests of which Aphis craccivora Koch. causes heavy damage to tender leaves of the plant and reduces its yield. The incidence of aphid was higher on the upper and middle canopy of the groundnut plant. Imidacloprid was found most effectively against aphids providing 85.47 % suppression, closely followed by mixed formulation Azadirachtin+tobacco providing 79.94% suppression and imidacloprid + Polygonum (79.18 % suppression). From over all observation it was found that mixed formulation Azadiractin+ polygonum, microbial toxin spinosad, botanical pesticide Azadiractin, tobacco leaf extract, extracts of Polygonum floral parts gave moderate to higher results, recording about 76.09 %, 75.07%, 71.77%, 57.59% and 55.35% aphids suppression respectively. When plant extract is mixed with plant based insecticides like azadiractin or small amount of chemical insecticide it provides better aphid control on groundnut. Plant extracts (bio-pesticides) having less or no hazardous effects on environment can be incorporated in pest management.
