Field surveys, molecular characterizations, and pathogenicity tests were carried out during the growing season of 2018. The most prevalent isolates obtained from the bean cultivation areas were Fusarium (62.5%) followed by Rhizoctonia (27.5%) and Rhizopus (4.8%). The lowest mean frequency rates were found for Epicoccum (0.7%), Penicillium (2.1%), and Alternaria (2.4%). Fusarium oxysporum (Y1A) had the highest virulence followed by Fusarium solani (Y1B) and Rhizoctonia solani AG-4 (Y8). The pathogenicity test on all bean varieties revealed that the disease severity rates of F. oxysporum, F. solani and R. solani AG-4 were ranging from 48.3%–91.7%, 33.3%–95.0%, and 26.7%–50%, respectively. Overall, the Adzuki bean cultivar was the most susceptible to the three pathogens followed by İspir, Gezin/Elazığ-1 and Kidney Bean cultivars.}, number={1}, publisher={Türkiye Fitopatoloji Derneği}, organization={Cukurova University}
