摘　　要：2018年,在武汉茭白(Zizania latifolia)产区对茭白细菌性基腐病田间发生动态进行调查,结果表明,6月下旬即可见田间为害症状,但一直到7月中旬,不论小区发病率还是植株发病率,均处于较低水平。小区发病率和植株发病率在6月下旬至8月上旬增加较缓慢,8月上旬至10月上旬则呈较快增加。种苗带菌、连作及高温是导致病害加重的重要因素。建议武汉地区对茭白细菌性基腐病的农药防治从8月上中旬开始。The field occurrence of bacterial basal culm rot of water bamboo(Zizania latifolia)was surveyed in Wuhan in 2018.The results showed that the injury symptoms were firstly observed in late June and both the plot incidence rate and plant incidence rate were at lower lever until the middle of July.The plot incidence rate and plant incidence rate both increased slowly from late June to early August and then rapidly from early August to early October.Seedlings infected with the disease,succession cropping and high temperature were probably the key factors which caused higher incidence rate.The paper suggested that pesticide control for bacterial basal culm rot of water bamboo should be begun in early August in Wuhan.
