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.
从苏丹不同地区收到了枯萎和腐烂的蚕豆植株。在几种镰刀菌属真菌中，分离出了奈氏镰刀菌。明显的症状包括黑根腐病，伴有侧根系统的腐烂和死亡。严重感染的植株在土壤层面出现黑颈溃疡。这些症状通常伴随着叶片膨压的丧失，叶片随后变成褐色并死亡。完整的叶片也会死亡。大多数菌株被证明对蚕豆具有致病性。病害严重程度在28%-100%之间变化。这是关于奈氏镰刀菌作为蚕豆病原菌的首次报道。
