Isolation and In vitro Compatibility of Fungal Antagonists of Mango Anthracnose with Fungicides

Abstract

The compatibility of antagonists of Colletotrichum gloeosporioides (Nigrospora spharica (Sacc.) E.W. Mason, Gliocladium roseum Bainier and Aspergillus sp.) in mango, with different   fungicides was tested through poisoned food technique. Two systemic fungicides viz., carbendazim (0.1% -1 g/L), hexaconazole (0.05% -1/2 ml/L) and a non-systemic fungicide viz., Sulphur (0.2% - 2g /L) were evaluated for their compatibility with potential antagonists. The antagonist Nigrospora sphaerica (95.56%) and Aspergillus sp. (91.11%) were most compatible with sulphur whereas Gliocladium roseum, was more compatible with Hexaconazol (73.11%). The results of present study are quite encouraging for the eco-friendly management of the mango anthracnose.
