摘　　要：为筛选抗晚疫病的马铃薯品种及化学药剂进行防治晚疫病,对16个马铃薯品种进行接种晚疫病菌试验比较及防治药剂室内平皿测定和田间实验,结果表明,不同品种间抗性有明显差异,坝薯10号与豫张薯5号是较抗晚疫病的品种,而中薯5号、中薯4号、紫花白851、鲁引1号、本9305-3和具夏坡帝为中抗,其余为易感晚疫病的品种。室内平皿测定灭克、安克和霜霉疫净对晚疫病菌具有较好的杀菌活性,田间药效试验安克、灭克和霜霉疫净也具有较好的防治效果,分别为84%、83%和81%。16 varieties of potato were tested for their resistance to potato late blight in green house.The result showed that there were differences in resistence among various varieties. 2 varieties(Bashu No.10 and Yizhangshu No.5) were of stronger resistance and 6 varieties(Zhongshu No.5, Zhongshu No.4, Zihuabai 851, Luyin No.1, Ben9305—3 and Xiabodi ) showed medium resistance, and the others were infective. Dimethomorph,flumorph and propamcarb had good fungicidal activity against Phytophthora infestans, and their ...
