Abstract: Eight fungicides viz. carbendazim, difenoconazole, hexaconazole, propiconazole, tebuconazole, pyraclostrobin, trifloxystrobin + tebuconazole and dinocap were evaluated under in vitro and greenhouse conditions. Difenoconazole was most effective in its efficacy as no conidia germinated and it was followed by the trifloxystrobin + tebuconazole (96.38%), tebuconazole (95.65%) and propiconazole (86.23%) while the carbendazim was least effective with 63.73 per cent inhibition amongst the tested fungicides but found superior to control and most effective fungicide in inhibition of germ tube elongation was difenoconazole followed by trifloxystrobin + tebuconazole (3.78 μm) and tebuconazole (4.10 μm) which showed superiority to other treatments including control while least effectiveness was recorded in carbendazim (29.24 μm). The highest disease control was recorded in difenoconazole of 85.96 per cent followed by trifloxystrobin + tebuconazole (83.60%), tebuconazole (82.07%), hexaconazole (78.99%), propiconazole (77.20%) and dinocap (71.97%). The least effective was carbendazim with 64.00 per cent disease control.
