Abstract: The efficacy of seed treatment with different fungicides viz., Carbendazim, Propiconazole, Hexaconazole, Validamycin, Tebuconazole, Thifluzamide, Azoxysrtrobin, Difenoconazole, Tebuconazole 50% +Trifloxystrobin 25% (Nativo) on the viability of sclerotia admixtured with the seed was tested, in which all the tested fungicides showed 100 per cent inhibition of sclerotial germination in both wet and dry seed treatments. The seed admixtured with sclerotia was treated with different fungicides given above, and the effect of sclerotia on germination and seedling growth was tested by paper towel and pot culture methods. All the seed was germinated in both paper towel and pot culture methods. The efficacy of fungicides on seedling growth varied in both wet and dry seed treatments. All the tested fungicides showed increased seedling growth (root length and shoot length) except Carbendazim and Tebuconazole 50% + Trifloxystrobin 25% (Nativo) when compared to control in both paper towel and pot culture methods.
