Winter wheat plants were sampled during the spring and autumn to identify fungi associated with root rot in Alabama. Samples were taken from 61 fields in the major wheat‐producing areas of the state; 179 fungi were isolated, identified, and tested for pathogenicity. Of the fungi identified, 46 (26%) were Gaeumannomyces graminis var. tritici , 37 (21%) were Cochtiobolus sativus , and 55 (31%) were Fusarium species of which 37 (21%) were Fusarium oxysporum . Other fungi identified that were pathogenic on wheat were Rhizoctonia solani, Sderotium rolfsii , and Pythium spp. G. g. var. tritier was the main pathogen associated with diseased root and lower stem tissue of wheat in Albama.
