A new leaf disease of tea plant was found in Donggang district of Rizhao, Shandong Province. The infected parts were shrunken and malformed, turned brown, necrotic and named brown blight of tea. Two microorganisms were isolated from the edge of infected parts through tissue separation, and named as RC4 and RC3. Their separation rates were 67.1% and 32.9% respectively. According to morphology, culture characteristics, multi- sequence analysis and Koch's Postulates test, Glomerella cingulata f. sp. camelliae and Botryosphaeria dothidea were found to be the cause of disease. This was the first report that Botryosphaeria dothidea damaged the leaves of tea plant.
