Abstract
The results revealed that the IPM module consisting of GPBD-4 variety of groundnut resistant to late leaf spot and rust, seed treatment with Trichoderma @ 4 g/kg, foxtail millet as intercrop (7:1), installation of pheromone traps @ 2 traps/acre for monitoring of Spodoptera litura, spray of emamectin benzoate 5 SG @ 0.2 g/l at 45 and 60 days after sowing was an effective module in obtaining higher yield of groundnut (39.95 q/ha) and cost effective with cost benefit ratio 1:5 in comparison to module-I and module-III (Farmer's practice).
