title: Fusarium nygamai.A causal agent of root rot of Vicia faba L. in the Sudan.
abstract: Wilted and rotted plants of Vicia faba were received from different localities in the Sudan. Among several Fusarium spp., Fusarium nygamai was recovered. Conspicuous symptoms were among others black root rot, associated with rot and death of the lateral root system. Severely infected plants showed black neck canker at soil level. These symptoms were usually accompanied by loss of the leaves' turgor, these then turned brown and died. Death of intact leaves also occurred. Most of the strains proved to be pathogenic to Vicia faba. Disease intensity varied between 28-100%. This is the first report of Fusarium nygamai as a pathogen of Vicia faba.
