Antifungal Properties of Extracts of Ipomoea carnea Jacq. Subsp. fistulosa Against some Vegetable Pathogenic Fungi.

Ipomoea carnea Jacq. subsp. fistulosa (Mart. ex Choisy) extracts were tested using the well in agar method against Fusarium oxysporum and Rhizopus stolonifer to find out their antifungal activity. Chloroform, ethanol, and aqueous extracts of leaf, stem, and root bark were used in the in vitro studies. All organs of selected plant with different extracts showed variable antifungal activity. Maximum activity was seen with the Leaves alcoholic extract, however minimal activity was found in the root extract (aqueous) with the test fungus. All test organisms showed radial growth inhibition in response to the extracts being added to the culture medium. The test organisms responded differently to the various extracts, but in overall, growth inhibition shows stronger with each extract's concentration. In plant and organisms, the antifungal activity was discovered to be in ascending from root bark then stem bark and highest in leaves. [ABSTRACT FROM AUTHOR]
