| Abstract: | The strains of Rhizoctonia isolated from wheat, millet, corn, rice and sorghum in Henan were identificated according to whether their hypha could anastomose with that of the standard strains. The strain isolated from whaet belonged to binucleate Rhizoctonia AG-B(0). The strains isolated from both corn and rice belonged to Rhizoctonia solani AG-1-IA. The strain isolated from millet belonged to R. solani AG-1-IC. The strain isolated from sorghum belonged to R. solani AG-5. The results of artificial inoculation in the field showed that the five strains belonging to four AG could all infect wheat, corn, rice, millet and sorghum, and cause typical symptoms of sheach blight. The rate of infection all reached 100 per cent. The pathogenicity of strains belonging to different AG was different. The pathogenicity of strains belonging to the same AG was alike. |
