Abstract: The nine different fungicides were evaluated in the Department of Plant Pathology, University of Agricultural Sciences, Dharwad during 2013 to identify the best chemical and required concentration of fungicides against Alternaria carthami. Systemic fungicides viz., hexaconazole, difenconazole were equally effective with 100 per cent inhibition at all the concentration tested which was on par with propiconazole (100%) at 0.15 per cent concentration and least effective chemical was found to be carbendazim (33.89%) at 0.05 per cent concentration. Among non-systemic and combi products, Zineb 68% + Hexaconazole 4% 72 WP was effective with 100 per cent inhibition at all the concentrations tested and Carbendazim 25% + Iprodione 25% 50 WP (100%) at 0.25 per cent concentration were significantly highest inhibition over other chemicals and concentrations and least mycelia growth was observed in Mancozeb 80% WP (47.78%) at 0.1 per cent concentration. The present result indicated that systemic fungicides and combi product fungicides are more effective than non-systemic fungicides under in vitro condition.
