Abstract: Background and Objective: Fusarium Head Blight (FHB) caused by several Fusarium species is a dangerous disease of wheat and small cereals particularly in humid and sub-humid areas throughout the world. A loss due to FHB disease includes both grain yield and quality (that affect human and animal health). This investigation was aimed to identify FHB pathogens that cause blighted spikes in wheat across southwestern Ethiopia. Materials and Methods: A total of 269 single conidial isolates of Fusarium spp. were recovered from 52 FHB samples collected across South Western Ethiopia (SWE). Based on their colony, macroscopic and microscopic features, all the isolates were identified into nine species within the genus Fusarium. Results: Among the nine identified Fusarium species, F. graminearum and F. culmorum were most frequently recovered from blighted wheat spikes in southwestern Ethiopia. All the nine identified Fusarium species were pathogenic to a susceptible Danda’a wheat variety. Based on their AUDPC and spikelet infection severity, F. avenaceum, F. poae, F. lateritium, F. culmorum, F. sambucinum, F. heterosporum and F. graminearum were more aggressive ones that produced higher AUDPC ranging from 546.8-1067.2 and higher spikelet infection severity ranging from 57.8-100%. Conclusion: This study reveals the existence of Fusarium species diversity in Ethiopia that caused FHB on wheat. The pathogenic nature of all identified species indicated that FHB will become a potential disease on wheat in the area.
