This study aimed to identify the Cinnamomum camphora canker disease pathogen in Fujian Province. We isolated, purified, and analyzed the pathogenicity of canker samples from four districts including Fuzhou City, Mingxi County of Sanming City, Jianyang District, and Shunchang County of Nanping City to determine the pathogen. The morphological characteristics of the pathogens were combined with the ITS, EF-1α, RPB2, and BT gene sequences of the representative strains for amplification and sequencing. This allowed the construction of the evolutionary tree, and the pathogens were finally determined. Among 75 dry ulcer samples collected from the camphor trees in different regions of Fujian Province, 43 pathogenic strains were obtained after tissue isolation, purification, and pathogenicity testing. Based on the status of mycelium growth and spore characteristics of pathogenic fungi and the results of phylogenetic trees, four strains were obtained, namely: Neofusicoccum parvum, Lasiodiplodia theobromae, Lasiodiplodia pseudotheobromae, and Lasiodiplodia iranensis. The pathogenicity test results showed that N. parvum was the strongest pathogen, followed by L. theobromae, and L. iranensis was the weakest. [ABSTRACT FROM AUTHOR]
