Alternaria is represented by about 50 species. Several forms of species are found as saprobes on dead & decaying plant part and in soil, while some forms of species are facultative parasite infecting a large number of higher plants. The fungus was grown as a pure culture in the Culture Room. The experiment was done to determine the efficiency of anti-fungal activity of Leaf extract of selected medicinal plants. Ricinus communis, Allium sativum, Azadiracta indica, Rauwolfia serpentina, Oscimum sanctum, and Withania somnifera were used for the extraction from leaf and cloves. In present investigation different concentration5, 10 and 15% were used in the culture. In the present study, it was observed that extract of Azadiracta indica at its all the three concentrations viz., 5,10 and 15% could inhibit the radial growth of the fungus which was 78.2, 85.4 and 88% respectively. It was further observed that leaf extract of Ricinus had the minimum inhibitory activity at all the concentrations used, that was 65.2, 70 and 76% only. It was observed that leaf extract of Allium sativum inhibited the radial growth at all its three concentrations which was next to Azadiracta leaf extract that was 74.32, 82 and 88% respectively. This was followed by leaf extract of Oscimum sanctum that was 72.67, 81 and 87 respectively. As a result, extracts from the leaves and cloves of many medicinal plants demonstrated antifungal efficacy at varying quantities and levels of action.
