依据比利时马铃薯晚疫病预警系统模型预测，确定马铃薯主要生育期内，病菌生成潜在侵染次数、代数和最佳防治期及防治次数，运用多目标决策方法，通过对西吉县‘青薯9号’品种马铃薯晚疫病田间药剂防治试验进行决策分析，获得了防治成本低（46.5～49.5元/667m2）、防治效果高（病指防效82.39%～85.78%）和保产效果好（41.40%～45.49%）的综合效益决策矩阵及决策靶，为指导马铃薯晚疫病田间防治提供了科学依据。

Based on a Belgium Warning System against Potato Late Blight, potential infection number, generation of Phytophora infestans de Bary, and optimal spray time and number of spray were determined using a multi-objective decision method. Based on the analysis on a field trial for late blight control of 'Qingshu 9' in Xiji County, decision-making matrix and target were established for low cost (46.5-49.5 Yuan/667m2), high late blight control efficiency (efficiency for disease index 82.39%-85.78%),andhighyieldincrease (41.40%-45.49%). These data provide a sound base for guiding late blight control in field.
