采用定点监测、分级调查法对云南河口地区香蕉黑星病的发生规律进行研究。结果表明：降雨量及温度的异常变化对香蕉黑星病的发生危害影响最大。河口县香蕉黑星病从4月底5月初开始发病，7月份开始迅速扩散，9～10月份达到高峰值，发病率为80%～100%，且高发病率维持至12月份；不同栽培地区香蕉黑星病的危害率及病情指数差异较大，危害率依次为河口东部地区＝65.5%＞中南部地区＝51.44%＞西部地区＝48.78%，不同海拔高度的危害率及病情指数呈现出海拔越高危害性越大的趋势。

Fixed-point monitoring and classification survey was investigated in order to study the occurrence regularity of banana scab in Hekou Yunnan. The results showed that the occurrence and harm in banana scab are seriously impacted by rainfall and temperature in Hekou. It occurred from the end of April or the early May, and the disease quickly spread in July. Especially, the high peak appeared in September to October, at the same time the incidence of banana scab disease is 80% to 100%, that kept until December. The different cultivation areas had the different resistance to the harm rate and disease index of banana scab, the harm rate was 65.5%in southeast region, 51.44%in the middle of south region, 48.78% in west region. The higher the altitude, the higher the harm rate and disease index. The study results are important for production.
