Rose( Rosa chinensis Jacq),a traditional Chinese ornamental flower,is widely planted for landscaping in China. Diseases,together with their typical symptoms on R. chinensis in China,are presented in this review. Ten fungal,one bacterial,one viral and one physiological disease are noted in this study respectively. Two newly recorded diseases,rose leaf spot caused by Chaetomella raphigera and rose leaf blotch caused by Pestalotiopsis clavispora,are also described and illustrated. With the warming climate,the geographic distribution of rose diseases may expand and the losses cause by rose diseases are becoming more serious.Therefore,we must strengthen researches on host-pathogen-changing climate and pay more attentions on adapted management measures as well.
