| Abstract: | Emilia sonchifolia bacterial wilt was severely occurred in the field in Guangxi, China. The pathogenic bac- terium was confirmed by Koch postulate. Then Polymerase chain reaction (PCR)amplification was conducted using 16s rDNA universal primers to identify the pathogenic bacterium. PCR products sequencing results showed the path- ogenic bacterium had 99% homology to Ralstonia solanacearum. This is the first report of E. sonchifolia wilt caused by R. solanacearum. |
