| Abstract: | Hibiscus rosa-sinensis is an important landscaping plant in Nanning, Guangxi. In 2019, a new stem rot disease was found in H. rosa-sinensis planting area in Nanning. Six diseased samples were collected, and six fungal isolates were isolated and purified from these samples. The fungi were identified as genus Lasiodiplodia based on morphological characteristics of colony and spore. Combined with the text of Koch's rule and a multi-gene phylogenetic tree with sequences of rDNA-ITS, EF-α and β-tubulin, we confirmed that L. theobromae was the pathogen of the new stem rot disease in Nanning. This is the first report on L. theobromae causing H. rosa-sinensis disease in China. |
