Abstract:
The efficacy of fungicides (7 systemic, 4 non-systemic and 6 combo) was tested at different concentrations of 20, 50, 100, 200 and 500 ppm against S. rolfsii on PDA by poisoned food technique in vitro condition and seed treatment with fungicide under pot experiment. It was concluded that systemic fungicides like, Hexaconazole 5% EC, Propiconazole 25% EC and combo products Tubaconzole 50% + Trifloxystrobin 25% WG, Captan 70% + Hexaconazole 5% WP, Propiconazole 13% + Difenoconazol and Carboxin 37.5% + Thiram 37.5% showed complete inhibition of the pathogen at all the concentrations tested. Whereas, the non-systemic fungicide Mancozeb 75%WP, Thiram 75% WS and Propineb 70% WP was found inhibitive only at higher concentrations (100 ppm) against S. rolfsii under in vitro condition. Similar results was found in case of seed treatment with fungicide under pot experiment.
