Among seven insecticides evaluated azadirachtin 10000 ppm (1 ml/l) was found to be the most effective against seed weevil Curculio c-album F., followed by deltamethrin 2.8EC (1.0 ml/l) and malathion 50EC (2.0 ml/l). The least effective was spinosad 45SC (0.3 ml/l) followed by cyantraniliprole 10.26OD (1.8 ml/l). Three rounds of sprays (new flush, pre bloom and post bloom) of insecticides gave better protection when compared to single/two sprays. Maximum healthy fruit yield (49.81 kg/tree) was obtained with azadirachtin.
