In vitro evaluation of safer fungicides in management of Penicillium digitaum causing green mould of Kinnow

Green mould, caused by Penicillium digitatum, is one of most destructive post-harvest disease of citrus worldwide. In vitro study, we examined the antifungal activity of commercially available fungicides viz. difenoconazole 25 % EC, hexaconazole 5 % EC, tebuconazole 25 % EC, propiconazole 25 % EC, kresoxim-methyl 50 % EC, azoxystrobin 25 % EC against Penicillium digitatum. Among these six fungicides, difenoconazole was found to be most effective as well as significantly superior to all other treatments with 99.2 per cent average inhibition in mycelial growth followed by hexaconazole with 97.2 per cent inhibition at 100 ppm concentration.
