Shruti Ojha, Dr. Mamta Goyal

Emblica officinalis is a member of Euphorbiaceae family, a valuable medicinal plant with enormous source of Vitamin C. It is used for curing diseases like cancer, diabetes, hypertension and high cholesterol. In agriculture, synthetic fungicides are used to control the fungal pathogens and diseases but causes harm to the environment, soil, water and plant quality. Research has been focused on the bio-control of fungal pathogens by plant extracts. Till date, bio-control of any disease from plant extract has not been done on Emblica officinalis from Rajasthan state. The objective of the research work focuses on the evaluation of medicinal plant extracts against Curvularia spp. on leaves of Emblica officinalis. The study investigated the antifungal properties of aqueous and ethanol extracts of Nerium indicum and Calotropis procera respectively by disc diffusion method. The results obtained were fully disease resistant when treated with the disc of plant extracts. Botanical aqueous extracts of Nerium indicum and ethanol extracts of Calotropis procera showed fully resistant properties against fungal growth of Curvularia species. The results concluded from the study that medicinal plant extracts have broad range of antifungal activity and could be useful in control on fungal diseases of plants.
