摘 要：
During 1990-1991,more than 240 root rot samples of citrus were collected from 15 counties in Sichuan,China and 518 isolations were obtained from these samples. Some isolations selected from them were tested for their pathogenicity to the 3 mo. old seedlings of Poncirus trifoliata (L. )Raf. , Citrus reticulata Blanco.and C. sinensis Osbeck. The results of the identification of the pathogenic isolations indicated that there are Pythium de-baryanum , P. hemmianum. P. hydnosporum, Pythium sp. -1 , Pythium sp. -2 , Phytophthora parasitica ,P. citrophthora ,P. palmivora ,Fusarium solani . F. oxysporumn, Rhizoctonia solani and Sclerotium bataticola attacking citrus roots in Sichuan ,China. The main species were Fusarium Solani, Pythium debaryanum, Pythium sp. Phytophthora parasitica , and P. citrophthora. They are widely distributed and frequantly isolated.
