| Abstract: | Through investigation,isolation and identification,we found that the pathogens of root rot diseases of cool-season turfgrass in Zhengzhou area were Fusarium spp.,Alternaria spp.,Rhizoctonia spp.,Drechslera spp.,Curvularia spp.and Pythium spp.etc.The result indicated that the dominant pathogens that caused lawn root rot disease in Zhengzhou were Fusarium solani and Rhizoctonia solani(AG-4) with highly isolation frequency and strong virulence. |
