INVESTIGATIONS ON FUNGICIDAL SENSITIVITY OF SCLEROTIUM ROLFSII (COLLAR ROT PATHOGEN) IN TUBEROSE

Six fungicides namely tilt (propioconazole), OPUS (epoxiconazole), Calixin (tridemorph), Indofil M-45(mancozeb), Blitox-50 (Cupper oxychloride) and Bavistin (Carbendazim) were evaluated against Sclerotium rolfsii causing collar rot of tube rose. At one hour of dipping of sclerotia in propioconazole significantly reduced the germination of sclerotia (26.7%). Carbendazim affected the germination but mancozeb could not reduce the germination. In in vivo evaluation of fungicides least mortality was found in propioconazole followed by epoxiconazole.
