Management of Pea powdery mildew by Fungicides, Botanicals and Bio-agents

The study was undertaken under field conditions to evaluate the efficacy of five fungicides, four botanicals and four bio-agents against powdery mildew of pea incited by Erysiphe polygoni. All the spray treatments were found effective against the disease and significantly reduced the powdery mildew intensity and thereby increased the seed yield and test weight in pea cv. Arkel over unsprayed control. The fungicides hexaconzole (0.05%) and penconazole (0.05%); botanical NSKE (5%) and bioagents Trichoderma horzianum (0.5%) were found highly effective and economical for controlling the disease and giving better seed yield.
