文摘The pathogen of Siraitia grosvenorii wilt was identified.Six strains were isolated from diseased plants of S.grosvenorii collected from Yongfu County in Guangxi.By using bacteriological identification,pathogenicity tests assay,16S rDNA sequence analysis,the S.grosvenorii wilt was caused by Ralstonia solanacearum.The results of pathogenicity and carbohydrate utilized test demonstrated that the pathogen belonged to race 1 and biovarⅢ of R.solanacearum.
