摘　　要：马铃薯晚疫病是会泽县马铃薯生产上的主要病害。试验开展了马铃薯晚疫病药剂的防治试验,探索不同处理方式,筛选出合适的防治药剂,为马铃薯晚疫病综合防治提供理论依据。结果表明:70%安泰生可湿性粉剂300倍液+68.75%银法利悬浮剂600倍液叶面喷雾2次防治马铃薯晚疫病,防效为76.25%,提高商品率,降低贮藏烂薯率,增产幅度大;68.75%银法利600倍液,每100 kg种薯用4～5kg药液喷湿种薯自然晾干种植,降低防治成本。Late blight is a devastating disease of the potato production in Huize County.In this research,experiment was carried out for late blight control by using fungicides in order to understand the effectiveness of different treatments and lay a sound base for integrated control of late blight.The control efficiency by application of 70% Antracol WP diluted 300 times + 68.75% Infinito SC diluted 600 times to the potato foliage two times was 76.25%.Under this treatment,the total tuber yield and marketable tuber p...
