Early Blight is a common potato disease, and agronomic measure is a better way to prevent and control the disease. The results in an experiment conducted in 2011 for early blight control by optimizing application rate of compound fertilizer indicated that the occurrence of early bight was associated with application rate, and when the fertilizer was applied at the rate of 60 and 40 kg/667m2, early blight control efficiency was 93.39% and 88.56%, yield increase was 26.61% and 22.18%, and net benefit was 405 and 365 Yuan/667m2, respectively, compared with the blank control. Therefore, application of potato compound fertilizer at the rate of 40-60 kg/667m2 could be an agricultural measure for prevention and control of potato early blight in the future for potato production.%马铃薯早疫病是一种常见的马铃薯病害，采用农艺措施控制病害的发生是一举多得的好办法。本试验通过施肥处理控制早疫病危害试验，结果表明，马铃薯早疫病发生早晚与施肥多少直接相关，施用60 kg/667m2和40 kg/667m2马铃薯复合肥，对早疫病防治效果为93.39%和88.56%，增产26.61%和22.18%，纯增效益405元/667m2和365元/667m2。因此，施40~60 kg/667m2马铃薯复合肥可以作为防治马铃薯早疫病发生的一项农业措施进行应用。
