| Abstract: | The tea leaf disease, which led to a large loss of production and decrease of quality, was found in the tea region in Huishui county, Guizhou province. Some strains were isolated from the diseased samples, and the representative strains fulfilled Koch’s postulate. Then the isolates were further identified as Lasiodiplodia theobromae based on morphological characters and phylogenetic analysis with internal transcribed spacer (ITS) and elongation factor 1-α (EF-1α) regions. The results showed that the pathogen of the leaf disease occurred in Huishui county, Guizhou province was L. theobromae. |
