Thread blight caused by Corticium koleroga is a devastating disease that causes severe damage to Coffea arabica in Ethiopia. However, it is one of the least researched diseases in Ethiopia. Therefore, the current work was designed with the objectives to (1) assess the intensity of the disease, (2) identify major factors associated with the disease intensity, (3) identify and characterize C. koleroga isolates and (4) determine the pathogenicity of C. koleroga isolates in southwest Ethiopia. For this purpose, field surveys were conducted on 180 farmers’ fields in 12 districts of southwest Ethiopia during 2017 cropping season. In addition, diseased samples were collected from 11 districts of southwestern Ethiopia during the study. The 11 C. koleroga isolates were characterized using macroscopic and microscopic features. The isolates were cultured on potato dext.. View more»
