Antifungal activity of medicinal plants against plant pathogenic fungus Colletotrichum falcatum

The antifungal activity of eight different medicinal plants namely Aloe vera, Ocimum sanctum, Cenetella asiatica, Piper betle, Calotropis gigantea, Vitex negundo, Ocimum basilicum and Azadirachta indica were tested against plant pathogenic fungus (red rot disease causing agent) Colletotrichum falcatum by agar well –diffusion method. The plants leaves were extracted with various solvents like chloroform, ethanol and aqueous. Among the different plant tested, all the three solvents of the Vitex negundo showed maximum antifungal activity (25 mm) against the plant pathogen tested. Whereas the other plant extracts were showed moderate to minimum antifungal activity.
