Biopesticides are mostly used to control fungal plant diseases because of their ecofriendly nature and their cost effectiveness. The present study focused on antifungal activity of solvent based plant extracts of common medicinal plants Azadirachta indica ,Tinospora cordifolia, Oscimum sanctum, Justicia adhatoda , Catharanthus roseus, Aegle marmelos, Aloe barbadensis, Tithonia diversifolia, Hyptis suaveolens and Pongamia pinnata were observed against soil borne phytopathogenic fungus Fusarium oxysporum by modified poisoned food technique. The methanol, ethyl acetate, benzene, acetone and chloroform extracts were evaluated for present study. The extracts of Azadirachta indica and Oscimum sanctum were most effective against Fusarium oxysporum. The present investigation suggests that acetone and chloroform extracts of Azadirachta indica and methanol extract of Oscimum sanctum acts as stong biopesticides and completely inhibit the growth of pathogen. This study reveals that these extracts contains amazing fungicidal properties and may be used as botanical biopesticides.
