Abstract:
Powdery mildew of chilli incited by Leveillula taurica (Lev.) Arn. is the major problem in chilli production. In vitro experiment was conducted to evaluate the efficacy of different fungicides, botanical and organic amendments against powdery mildew of chilli caused by Leveillula taurica (Lev.) Arn. Among all the fungicides Propiconazole 25% EC significantly cause maximum 100, 100 and 99.28% inhibition of spore germination with minimum 0, 0 and 0.58% spore germination at 0.2, 0.1 and 0.05% concentration. Among the botanical the Neem oil was observed most effective with 26.17, 28.75, 35.17, 36.90, and 45.52% spore germination and 67.48, 63.51, 56.30, 54.16 and 43.45% inhibition of spore germination at 15, 10, 7, 5 and 2% concentrations respectively and in the organic amendments Panchgavya was found most effective with 30.65,32.25, 36.80, 41.10 and 47.80% spore germination and 61.92, 59.31, 54.29, 48.94 and 40.62% inhibition of spore germination at 15, 10, 7, 5 and 2% concentrations respectively.
