摘要:
Idesia polycarpa is a woody oil plant with great development and application prospects. However, stem canker disease of I. polycarpa was frequently observed in Henan and Hubei provinces of China in 2020-2022. The seriousness of the disease caused a large number of trees deaths, which affected seedling production and fruit yield, restricting the development of the I. polycarpa industry. We performed isolation, purification and pathogenicity analysis of canker samples. Pathogenicity tests reproduced typical canker disease symptoms on detached branches of I. polycarpa. Based on morphological observations, conidial morphology and phylogenetic analysis of isolates with high similarity to the rDNA internal transcribed spacer (ITS), EF-1 alpha and TUB2 sequences screened in GenBank by BLAST, the pathogen of canker disease on I. polycarpa was identified as Botryosphaeria dothidea. This is the first report of B. dothidea as the pathogen of stem canker of I. polycarpa.
