Abstract

Fusarium basal rot (Fusarium oxysporum) of shallot is a destructive disease, which constrains the production and quality of this crop in Vinh Chau (Soc Trang, Vietnam). This study aims at screening wild plants with antimicrobial activities to bio-control the disease. Among aqueous extracts of 49 commonly found plant species in Vietnam, the 4% (w/v) leaf extracts of Annona glabra and Wedelia calendulacea exhibited strongest inhibitory effects on the mycelial growth of F. oxysporum (up to 35.3% and 25.7%, respectively) in disc diffusion assays. Furthermore, incubating the conidia in A. glabra extract (4%) resulted in a significant suppression in germination (up to 95.3%). Under net house conditions, soil drenching of both extracts at 4% and 5% concentrations showed an equivalent reducing effects on both disease incidence and severity in shallot plants compared to the chemical treatment. Thus, A. glabra and W. calendulacea show their potentials for large-scale applications to sustainably control Fusarium basal rot of shallot.
