摘　　要：为降低马铃薯晚疫病在生产过程中带来的损失,采用正交设计考察药剂品种、施用剂量、防治时期、施药次数对马铃薯晚疫病防治效果的影响。结果表明:各药剂处理对马铃薯晚疫病都有防治效果,其中50%烯酰吗啉(150 g/667m2)的防治效果最好,为87.64%;其次是75%代森锰锌(150 g/667m2),防效为84.85%。Effects of fungicide, dosage, treatment period, and application frequency on late blight were studied in an orthogonal design. The results showed that al the fungicides tested showed certain efficacy against potato late blight, of which 50%Dimethomorph（150 g/667m2）was the best, with control efficacy being 87.64%, and fol owed by 75%Mancozeb（150 g/667m2）, with control efficacy being 84.85%.
