Abstract:
The present investigation was carried out to evaluate the effect of different trap crops viz., Cluster bean (Guar), pearl millet (Bajra), sorghum (Jowar) and sesame (Til) and different mulches viz., sawdust, straw mulch, yellow and greyish blue polyethylene on disease severity, vector population and grain yield as an ecofriendly alternative approaches of chemicals under field condition against golden mosaic virus disease of cowpea. The results revealed that cluster bean sown as the trap crop was observed to be the best for reducing per cent disease intensity (56.93%), vector population (5.86 per plant) and increasing seed yield (84.23%). Out of four mulches, yellow polyethylene was found most effective in reducing per cent disease intensity (82.81%), vector population (2.33 per plant) and increasing seed yield (79.45%).
