In vitro evaluation of various bioagents against detected seed mycoflora of groundnut

Biotic and abiotic stresses are major constraints in the production of groundnut. Among biotic stresses apart from bacterial and viral diseases, many fungal diseases are of economic importance. The major fungal diseases are Early leaf spot (Cercospora arachidicola), Late leaf spot (Cercosporidium personatum), Rust (Puccinia arachidis), Botrytis blight (Botrytis cinera), Aflarot/Yellow mould (Aspergillus flavus), Damping off (Pythium spp.

In vitro evaluation of Trichoderma Harzianum and botanicals on the radial growth of Colletotrichum dematium causing anthracnose disease of groundnut (Arachis hypogaea L.)

A study was conducted in vitro to control Colletotrichum dematium causing anthracnose disease of groundnut with Trichoderma harzianum and botanicals. Five botanicals viz., Datura leaf extract, Tulsi leaf extract, Garlic bulb extract, Neem oil and Eucalyptus oil at the rate of 5% were evaluated for their efficacy against the radial colony growth of C. dematium. The complete inhibition was obtained in Eucalyptus oil (100%) followed by T. harzianum (71.01%), datura leaf extract (64.78%), tulsi leaf extract (63.63%), neem oil (49.14%) and garlic bulb extract (43.35%).
