Abstract
The antifungal activities and phytochemical screening of two invasive alien species: Ageratina adenophora and Ipomoea carnea ssp. fistulosa of Nepal were studied. Distilled water and methanolic extract of the leaves of plants were tested against five phytopathogenic fungi viz. Alternaria brassicae, Botrytis cinerea, Fusarium oxysporum, Phytophthora capsici and Sclerotium rolfsii at five different concentrations (50 mg/ml, 100 mg/ml, 150 mg/ml, 200 mg/ml, 250 mg/ml). The antifungal activity was performed by poisoned food technique; and linear mycelium growth reduction (LMGR) percentage was calculated. A qualitative phytochemical screening was performed for constituents such as tannins, saponins, terpenoids, alkaloids and flavonoids. The methanolic extract was more efficient as compared to the distilled water extract. A. brassicae, B. cinerea and S. rolfsii were found the most resistant fungi and F. oxysporum was found the most susceptible fungus. Out of two plants, A. adenophora was found more active against selected pathogens than Ipomoea carnea ssp. fistulosa. It can be concluded that the tested plants possess antifungal properties which may be used as alternative fungicides after further investigation.
