摘　　要：4种药剂对马铃薯晚疫病田间防效试验结果表明,4种药剂对马铃薯晚疫病防治均有不同程度的保叶增产效果,其中687.5 g/L银法利悬浮剂800倍液、25%瑞凡悬浮剂1 700倍液对马铃薯晚疫病防效最显著,马铃薯产量均比喷清水增产130%以上,53%金雷多米尔水分散粒剂500倍液、52.5%抑快净水分散颗粒剂1 000倍液效果次之。Control efficacy of four fungicides on potato late blight was determined in field experiment.The results showed that four fungicides were effective for potato late blight control and yield prevention.The best fungicide was 687.5 g/L of fluopicolide 800 times liquid and 25% of mandipropamid 1 700 times liquid.Yield was increased by 130% compared with the water control.The second control efficacy of fungicides was 52.5%famoxate 1 000 times liquid and 53% ridomil gold 500 times liquid.
