Every spring since 2001, large areas of the new forested poplar died in north of Jiangsu Province. In poplar branches that had died or were nearly to die, there were spots similar to the symptoms of canker disease. By isolation, inoculation and re-isolating the Koch’s principle was completed and finally based on the sequence of ribosomal DNA-ITS,the pathogen was identified as Phomopsis eucommiicola C.Q. Chang, Z.D. Jiang & P.K. Chi, This paper was the first report about Phomopsis eucommiicola causing canker disease on the new poplar forestation.
