| Abstract: | Euphorbia pulcherrima has been attacked in recent years by a kind of bacteria which caused bacterial blight in a flower nursery in Danzhou city, Hainan Province. The symptoms of this disease was described and its pathogen was identified as Xanthomonas campestris pv. poinsettiicola based on stain reaction, morphological, cultural, physiological and biochemical properties as well as the host range of the pathogen. It is first reported that Euphora heterophylla,Euphorbia millii and Manihot esculenta are new inoculated hosts in China, and that Hevea brasiliensis and Ricinus communis are new inoculated hosts both at home and abroad. |
