Abstract

The anti-fungal activity of ethanolic and petroleum ether extracts of eight medicinal plants, viz., Acorus calamus Linn, Justicia adhatoda L. Lawsonia Inermis L., Lantanacamara Linn., Pongamiapinnata (L.) Pierre, Solanum nigrum Linn., Vitex negundo L. and Wedelia chinensis (Osbeck) Merr. were tested in vitro against phytopathogenic fungus Sclerotium rolfsii Sacc. was evaluated using poison food method. The results obtained showed that the Petroleum ether extracts of leaves and flowers of L. camara, leaves of Lawsonia inermis and S. nigrum did not inhibit the growth of S. rolfsii. However, it was observed that the ethanolic extracts of the rhizome of A. calamus and the leaves of L. Camara showed 61% and 50% inhibition of the growth of S. Rolfsii respectively. The most promising results were obtained with the petroleum ether extract of A. calamus, which exhibited 100% inhibition of S. Rolfsii with MIC of 10.4 mg/ ml.
