试脸在田间测定了克露、迭克宁、银法利、瑞凡和中药杀菌剂5种药剂对马铃薯晚疫病的防治效果。结果表明：5种药剂对马铃薯晚疫病均具有明显的防治效果和增产效果，防治效果最好的是银法利，其次为瑞凡、达克宁、克露和中药杀菌剂，增产62%-155％，晚疫病烂薯率为1．20％-8．09％。根据病害发展曲线，病害发展前期使用5种药剂。均可达到显著防治效果。病害发展后期，建议选择银法利和瑞凡药剂。注意每种药剂交替使用，避免产生抗药性。

Control efficacy of five fungicides on potato late blight was determined in field experiment. The five fungicides had obvious effects on potato late blight control and increased yield. The best fungicide was Fluopicolide, followed by Mandipropamid, Chlorothalonil, Cymoxanil ＋ mancozeb and Matrine. Yield was increased by 62%-155% compared with control, and tuber rot percentage was only 120%-8.09%. According to the test curve of disease development, all of the five fungicides used in the prophase of disease development could achieve a significant control effect. In the anaphase of disease development, however, Fluopicolide and Mandipropamid were recommended. Each fungicideshould be used altemativelytoavoid resistancetofungicides
