Evaluation of an effective cultural management practices for the management of gall weevil Alcidodes collaris (Pascoe) in pigeonpea

Abstract

Pigeonpea is an important pulse crop is known to attack by wide range of insect pests from seedling stage to storage. Among these, recently gall weevil causing threat to pigeonpea at seedling stage. Investigation on management of gall weevil using cultural practices revealed that less incidence of gall weevil was recorded in redgram intercropped with cowpea with only 1.17 galled plants per 10 plants and also highest percent reduction of galled plants over control (82.45 %). Followed by redgram + soybean with 2.33 galled plants per 10 plants and 65.07 percent reduction of galled plants over control. Redgram equivalent yield of intercrop added to redgram yield was significantly higher in redgram+ cowpea (28.87 q/ha) intercropping system.
