Biological activity of selected plant ethanolic extracts against phytopathogenic fungi, Fusarium oxysporum f.sp. cicer

Abstract

In this present study six different plants used in traditional Sudanese medicine; Allium sativum L. (Liliaceae), Azadirachta indica (Meliaceae), Capsicum frutescence L. (Solanaceae), Momordica balsamina (Cucurbitaceae), Petroselinum crispum (Apiaceae) and Pulicaria undulata L.(Asteraceae), were examined against Fusarium oxysporum f.sp. cicer., the causal agent of vascular wilt in chickpea. We used disc agar method to determine the in vitro antifungal activity of these plants. The ethanolic extracts of studied plants exhibited varying degrees of inhibition activity against the tested fungi. Among the 6 plants studied only two plants (A. sativum, P. crispum) showed high activity, other plants (M. Balsamina, A. indica, C. frutescence, P. undulata) showed moderate activity. These results suggest that the plants may have individual components that can be useful for managing Fusarium oxysporum f.sp. cicer.

Keywords: Fusarium oxysporum f.sp. cicer., inhibition activity, medicinal plants, inhibition zone.
