Integrated management of pea powdery mildew caused by Erysiphe Polygoni DC.
Keywords:
Pea, Powdery mildew, Erysiphe Polygoni DCAbstract
Pea (Pisum sativum L.) occupies a prominent place in the vegetable cultivars in India. Powdery mildew disease on pea (Pisum sativum L.) incited by fungus Erysiphe polygoni DC is an important limiting factor in pea cultivation in Marathwada region of Maharashtra state. In the integrated disease management trial application of different bioagents showed reduced disease severity. The disease severity ranges 13.84 to 27.68 per cent. Treatment Trichoderma hamatum was most effective followed by Trichoderma viride and Pseudomonas fluorescences. In Chemical management experiment the fungicide Bayleton (0.05 %) showed significantly lowest disease severity (15.93 %) with maximum (26.87 %) disease control. On the basis of effectiveness in controlling the powdery mildew disease of pea the most effective fungicide recorded in the order of merit were Bayleton (0.01 %), Tridomorph (0.05 %) and Dinocap (0.05%).
