Abstract:
Alternaria alternata is the wide spread pathogen causing leaf blight disease in Spanish jasmine (Jasminum grandiflorum L.) an important flower crop of commerce widely grown in India. Generous spectrum of effective fungicides is in use against this pathogen. The indiscriminate use of chemical fungicides is not only expensive but also hazardous for all living organisms. With this view the study was conducted to find a bio fungicide against Alternaria alternata. Twenty-four plant extracts and four oils were screened for antifungal activity under in vitro condition. Among the tested plant oils and plants products clove extract of Allium sativum (5%) recorded the highest reduction of the mycelial growth of 100% followed by leaf extract (10%) of Datura metel (68.44%) and oil (3%) of Azadirachta indica (59.88%). The effective plant extracts and oils have potential to be developed as potent fungicides in organic farming.
