Abstract
This experiment evaluated some IPM modules against pests of common bean Phaseolus vulgaris, and observed that the module with soil application of carbofuran 3G @ 32.5 kg/ ha+1st of spray with dimethoate 30EC @ 0.03% (45 days after sowing- DAS) and 2nd with dichlorvos 76SC @ 0.076% (70 DAS) was the most effective. This resulted in maximum reduction of pests (76.85, 75.43, 69.97% of aphid, whitefly and weevil, respectively) and resulted in maximum gross returns (`₹94,068), net returns (``₹64,017) and benefit cost ratio (2.13). Besides, these effect of intercropping of beans with maize revealed a reduced population density of all the major pests, as compared to sole bean crop.
