Different non systemic, systemic and combi product fungicides were evaluated in vitro against Sclerotium rolfsii, Rhizoctonia bataticola and Fusarium solani causing wilt of betelvine. Among the non systemic fungicides evaluated Captan showed maximum per cent inhibition in mycelia growth of S. rolfsii ( 62.96 ), R. bataticola (85.93) and F. solani (84.07) at 0.3% concentration. Among the different systemic fungicides tested, Hexaconazole and Propiconazole at 0.15% concentration showed cent percent inhibition against S. rolfsii, Propiconazole showed cent per cent inhibition of R. bataticola.. Tebuconazole and Propiconazole showed cent per cent inhibition of F. solani. Among the combi-products tested Captan 70 %+ Hexaconazole 5% WP (Taqat) showed cent per cent inhibition against S. rolfsii and F. solani at 0.1, 0.2 and 0.3% concentration, for R. bataticola at 0.2 and 0.3% concentration. Least inhibition in mycelia growth was recorded in Tricyclazole 18% + Mancozeb 62% WP (Merger).
