| Abstract: In order to effectively prevent and control strawberry root rot, the pathogen of strawberry root rot in Xuzhou was isolated and identified by tissue isolation method. After isolation and purification, five fungal strains were obtained. Compared with the results of morphological and molecular biology base sequence determination, it was found that CMGF-1 was Colletotrichum gloeosporioides or its subspecies, CMGF-2 and CMGF-3 were Colletotrichum cladosporium or its subspecies, and CMGF-4 and CMGF-5 was Fusarium continuum or its subspecies. The pathogenic bacterium of black root rot was mainly Fusarium spp. and Polychaeria disciformis , while the pathogenic bacterium of red stele root rot was Colletotrichum gloeosporioides . |
