摘要：
A stem canker disease of Tatarian dogwood (Cornus alba) was observed in Shandong province of China in 2008. The pathogen was isolated from typical canker tissues and fulfilled Koch's Postulates. The morphological characteristics of the pathogen were determined and the internal transcribed spacer (ITS) region of the rDNA, the translation elongation factor 1-alpha (EF1-alpha) and beta-tubulin (BT) were amplified by PCR for molecular identification. On the basis of the symptoms, morphological characteristics and sequence data, the pathogen was identified as Botryosphaeria dothidea (anamorph Fusicoccum aesculi). This is the first report of this pathogen on Tatarian dogwood in China, and to the best of our knowledge, the world.
