In vitro and glass house evaluation of fungicides against the pathogens associated with rhizome rot complex of ginger in Kumaon region of Uttarakhand

Abstract

Of the nine fungicides tested under in vitro conditions, carbendazim was found to be most effective fungicide provided complete inhibition of Fusarium acuminatum at all the concentrations tested. While, azoxystrobin, pyraclostrobin, tebuconazole, copper oxychloride, carbendazim, propiconazole and metalaxyl-M 4% + mancozeb 64% showed complete inhibition of Pythium aphanidermatum at all the tested concentrations. It is evident that all the fungicidal rhizome treatments significantly reduced the rhizome rot incidence and also resulted in improvement in germination as compared to control. However, the treatments wherein rhizomes were treated with fungicidal combinations were proved best compared to single fungicide except carbendazim + copper oxychloride, metalaxyl-M 4% + mancozeb 68%, metalaxyl 8% + mancozeb 64% and carbendazim + tebuconazole @ 0.2% were found best and equally effective.
