摘要：根据比利时（C. Ducattillon）CARAH马铃薯晚疫病预警系统预测结果确定马铃薯晚疫病菌侵染时间进行施药，第一次侵染施用代森锰锌1次，第二、第三、第四次侵染分别使用银法利、抑快净、烯酰吗啉、克露、甲霜灵·锰锌、双炔酰菌胺各3次。结果表明，6种组合使用对马铃薯晚疫病均有较好的防治效果，且随着用药次数的增加防效提高，最后一次药后7 d防效分别为94.89%、87.44%、94.11%、88.22%、81.00%、93.67%，增产幅度达5.63%～24.69%。

Abstract：Spraying for controlling potato late blight according to the potato late blight infection occurrence time predicted by warning system of CARAH， Mancozeb was applied in the first spraying while fluopicolide propamocab hydrochloride， famoxadone cymoxanil，dimethomorph， cymoxanil Mancozeb， metalaxyl Mancozeb and mandipropamid were applied for 3 times in the following 3 infections. The results showed that the control effects of the 6 fungicide combinations against potato late blight were good. The control efficiency 7 d after the last spraying was 94.89%， 87.44%， 94.11%， 88.22%， 81.00%， and 93.67% respectively； and the yield was increased by 5.63%～24.69%.
