2011~2013年西吉县应用比利时马铃薯晚疫病预警系统预测预报模型，确定3个区域马铃薯主要生育期内，病菌生成潜在侵染的次数和代数，准确地预报晚疫病发病期，确定最佳防治期及防治次数。通过监测指导统防统治田病指为3.56~7.12，农户自防区病指为8.05~16.55，空白对照区病指达21.13~40.45，比农户自防提高防效54.56%~72.30%、保产27.35%~36.03%，取得了显著的经济效益，并减少了杀菌剂施用量，保护了生态环境。

The potential infection times and generation of Phytophora infestans de Bary on potatoes in three areas were predicted in growing season of Xiji County in 2011-2013, and the late blight occurrence date and thereafter optimal date and number of fungicide application were determined based on a Belgium Warning System against Potato Late Blight. The disease index was 3.56-7.12 for potato field sprayed based on the warning system, 8.05-16.55 for field sprayed by farmers, and 21.13-40.45 for blank control, increasing control efficacy by 54.56%-72.30%and yield by 27.35%-36.03%compared with late blight control by farmers and therefore significantly increasing economic benefit and reducing environmental contamination by reducing the amount of fungicide used.
