Abstract

The intercropping had significant difference in reduction of pod damage, grain damage (in number & by weight basis) as compare to pigeon pea monocrop. The two sprays of biopesticides were found most effective in reducing crop losses incurred by pod bug. The intercrops pigeon pea + rice, pigeonpea + sorghum and two sprays of NSKE 5% were found most effective combination for the management of pod, grain and grain weight loss by Clavigralla. gibbosa. The plots devoid of biopesticidal treatment had 15.8 to 16.8%, 6.3 to 7.3% and 3.4 to 4.8% pod damage, grain damage and grain weight loss, respectively.
