| 摘 要： | 玉米灰斑病模拟结果表明,LOGISTIC模型最能反映该病害流行动态,其次为GOMPOERTZ模型。该病害流行阶段为指数增长期从玉米出苗开始到7月上旬,逻辑斯蒂期从7月上旬到8月下旬,衰退期从9月上旬到玉米生育期结束。该病害防治时间在6月下旬。

| Abstract: | The LOGISTIC model can reflect well the development process of gray leaf spot in field by artificial inoculation.Next is GOMPOERTZ.The results showed that the exponential phase of gray leaf spot was from the breeding to the early of Jul.,the Logistic phase was to the later of Aug.,and the terminal phase was from the early of Sep.The optimal prevent time was the later of June. |

| Keywords: | Gray leaf spot LOGISTIC model Epidemics phase of plant disease Prevent time |
