Four sterol inhibiting fungicides (flutriafol, hexaconazole, myclobutanil and fenarimol) were found effective in their curative activity. Flutriafol (Impact) was used for the first time against apple scab and was found to be promising one. Curative activity of these fungicides was excellent when applied 72 h after inocultaion. but beyond this interval their activity either decreased or was not static.
