[Method] The fungal species, distribution and the diseases caused by Fusarium Link in Ningxia Hui Autonomous Region were determined by the methods of field investigation, collection, isolated culture and identification. [ Result] Nine species of fungi belonging to Fusarium Link were identified, including F. avenaceum, F. concolor, F. culmorum, F. graminearum, F. moniliforme, F. nivale, F. oxysporum, F. solani, and one unnamed species. They were distributed throughout Ningxia Hui Autonomous Region and caused more than 30 kinds of plant diseases. [ Conclusion] Fusarium Link had many species in Ningxia Hui Autonomous Region without regional features, and all of them were plant pathogens.展开更多
