茶饼病第1次在丽水市茶区发生于2010年秋,病原菌形态学观察和接种试验证实该病害的病原菌。病害抗病性观察显示,不同茶树品种对该病害抗性明显不同,其中迎霜品种相对最感病;每年4~6月和8~10月期间雨量与病害的发生密切相关;在海拔260~520βm范围内,因不同海拔高度茶园的雨日、雨量、相对湿度不同,病害发生情况各异;60%遮荫的茶园极有利于茶饼病发生。生长季节结束后,科学修剪及处理修剪枝叶、冬季清园封园等农业措施,对病害控制效果达到28.86%~49.62%。

The occurrence of tea blister blight in Liushui city was first observed in the fall of 2010. Later, the pathogen for tea blister blight was confirmed by combination of fungal morphological characters and inoculation testing. The disease resistance to host plants showed that different cultivars of tea plant demonstrated distinctively different resistance, and the cv. Yingshuang showed most susceptible to the disease. Also, disease occurrence had a close relation with rainfall in the two periods, i.e. from April to June and August to October. In terms with altitude scope from 260 to 520 meters above sea level, different altitude had various rain days, rainfall and humidity through which the disease occurrence can be often affected. Additionally, the shade degree in tea garden was also closely related to the disease severity. Result showed that 60% of shade degree was the most favorable situation for the disease occurrence. After the end of growing season, some agricultural measures could be scientifically taken, such as pruning the diseased leaves and taking them away as well as cleaning and closing tea gardens, through which control effect can reach up to 28.86%~49.62%.
