| Abstract: | Cherry leaf spot disease is one of the most common diseases of sweet cherry. In 2018 and 2019, a leaf spot symptom was observed on sweet cherry in Beijing city, Shandong province and Liaoning province, and the pathogen fungi were isolated from diseased samples. Seven fungal isolates (JZB310197-JZB310203) were identified as Botryosphaeria dothidea according to morphological characteristics and multi-gene (ITS, EF 1-α and TUB2) phylogenetic analysis. To fulfill the Koch′s postulation, pathogenicity assay was carried out on detached leaves and tissue cultured seedlings. The inoculation results showed that all isolates were pathogenic to cherry leaves, proving that B. dothidea was a pathogen of cherry leaf spot disease. This is the first report of B. dothidea causing leaf spot of sweet cherry in China. |
