Powdery mildew of black gram incited by Erysiphe polygoni (De Candolle) is the major problem in black gram production; it causes both quantitative and qualitative losses of grains. In vitro experiment was conducted to evaluate the efficacy of different fungicides, botanical and organic amendments against powdery mildew of black gram caused by Erysiphe polygoni DC. Among all the fungicides new combi-fungicide Taspa 300 SC [Propiconazole (13.9%) 15% W/V + Difenconazole (13.9%) 15% W/V] significantly cause maximum 93.05, 92.1 and 89.23% inhibition of spore germination with minimum 5.32, 6.05 and 8.24 % spore germination at 0.2, 0.1 and 0.05% concentration. Among the botanical the Neem leaf extract was observed most effective with 28.32, 30.53, 32.85, 35.62 and 42.63% spore germination and 62.14, 59.18, 56.08, 52.38 and 43.01% inhibition of spore germination at 15, 10, 7, 5 and 2% concentration respectively and in the organic amendments Panchgavya was found most effective with 30.50, 32.15, 34.98, 39.36 and 45.51% spore germination and 59.22, 57.02, 53.24, 47.38 and 39.16% inhibition of spore germination at 15, 10, 7, 5 and 2% concentrations respectively.
