In-vitro efficacies of different fungicides against stem rot disease of ginger incited by Sclerotium rolfsii. sacc.

Abstract

In vitro evaluation of systemic and non-systemic fungicides indicated that all the test fungicides significantly inhibited mycelial growth of S. rolfsii over untreated control. Among the systemic fungicides tested, highest average inhibition recorded by Carboxin and Hexaconazole was found most effective with per cent (100%) inhibition of mycelial growth. This was followed by the fungicides viz., Carbendazim (90.72%), Metalaxyl (80.59%), Tridemefon (78.55%) and Thiophanate methyl (70.02%). Among the non- systemic fungicides tested, highest average inhibition recorded by Cymoxanil + Mancozeb was found most effective with per cent (100%) inhibition of mycelial growth. This was followed by the fungicides viz., Mancozeb (92.07%), Captan (75.12%), Copper oxychloride (60.95%) and Bordeaux mixture (41.18%).
