Poplar bark lesions with vesicular canker were collected,isolated and molecularly identified in the labora-tory to determine the pathogen species,and the antibacterial test of chlorothalonil against the pathogen was carried out.The results showed that the pathogen was identified as the pathogen of poplar vesicular canker.The sexual stage was Botryosphaeria dothidea,and the asexual stage was Dothiorella gregaria.The inhibition rate of chlo-rothalonil 600 times dilution on poplar vesicular canker reached more than 90％,and chlorothalonil had a good inhibi-tory effect on poplar vesicular canker.
