EFFECT OF FUNGICIDES ON MYCELIUM GROWTH OF SCLEROTINIA STEM ROT CAUSED BY SCLEROTINIA SCLEROTIORUM IN INDIAN MUSTARD

Abstract

The experiment was conducted at Department of plant Pathology, College of Agriculture, RVSKVV, Gwalior (M.P.) during 2014-15. It was carried out to evaluate the efficacy of different fungicides on mycelial growth of Sclerotinia stem rot caused by Sclerotinia sclerotiorum under in-vitro by poisoned food technique. From the present study it could be concluded that carbendazim 50% WP, propiconazole 25% EC and thiophanate methyl 70% WP were recorded completely inhibited mycelial growth and formation of sclerotia, followed by hexaconazole 5% SC (80.46% and 0.667), thiram 75% SD (72.65% and 1.333), ridomil (71.08% and 1.333) and mancozeb 75% WP (69.53% and 0) were found least effective but copper oxychloride 50%WP (44.13% and 1.333) and sulphur 80% WDG (13.66% and 2.333) were inhibited at par control (0.00% and 3.333) on mycelial growth and formation of sclerotia respectively.
