| Abstract: | The fungus isolates were obtained from the stem nodes of diseased winter wheat grown in Linxia region,Gansu province.These isolates were identified as Fusarium nivale(Fr.) Ces.,Fusarium avenaceum(Corda et Fr.) Sacc.,Epicoccum tritici P.Henn.,Diplodiella sp.,Alternaria spp.,Cladosporium sp.,Nigrospora spp.,respectively.Fusarium nivale was the most pathogenic species, while Fusarium avenaceum was moderately virulent.Epicoccum tritici was only slightly virulent,whereas the others were all nonpathogenic. |
