1 . This paper deals with the presence of brown blight fungus in tea plants and the results of experiments on the hot water treatment of the seeds of tea plants as one of the control measures.
2 . Guigardia fungus was isolated from every part i. e. leaves, branches, sprouts, fruit receptacles, ete. of tea plants which were regarded as healthy. Besides this fungus, Fusarium and other fungi were isolated from them.
3 . The optimum temperature for the mycelial growth and spore germination lies at 25-35℃. The lethal temperatures of spores lies at 50℃ for 40 minutes and of the mycelia lies at 50℃ for 20 minutes.
4 . Causal fungi were isolated from the seeds of tea plant treated with hot water for 30 minutes at 53℃, but not in higher temperatures than 55℃. The germination of the seeds was slightly inhibited by means of hot water treatment at 58℃ for 10 minutes. These results might show the possibility of controlling the brown blight with hot water at 53℃ for 10 minutes.
