Abstract

Pigeonpea is attacked by many insect pests, and of these the gall weevil Alcidodes collaris (Pascoe) causes threat to pigeonpea at seedling stage by attacking basal portion of the stem and resulting in the gall formation. Evaluation of some insecticides revealed that less incidence was observed using seed treatment with imidacloprid 600FS followed by chlorantraniliprole 18.5SC spray (1.17 galled plants/ 10 plants) after 20 days of emergence. This also resulted in maximum reduction of galled plants (79.37%). Imidacloprid 600FS seed treatment with drenching of profenophos 50EC at 20 days after the crop emergence was observed to be the next best. Seeds treatment with imidacloprid 600FS followed by chlorantraniliprole 18.5SC spray gave maximum yield of 23.38 q/ ha.
