摘要：马铃薯晚疫病是世界性大病害,选用适宜的杀菌剂有效地防治马铃薯晚疫病对马铃薯安全生产、促进经济发展具有重要意义.试验以"陇薯3号"为试验材料,制订了马铃薯叶片晚疫病病情分级标准和贮藏期间块茎晚疫病病情分级标准,通过计算晚疫病病情指数和防治效果,研究分析了甲霜·锰锌、克露、硫酸铜钙、抑快净、丁子香酚、银法利、百泰和广枯灵等8种杀菌剂对马铃薯晚疫病的防治效果.试验结果表明:大田防治马铃薯晚疫病时,丁子香酚的防治效果最好,防治率高达79.67%;马铃薯库存期间,银法利对马铃薯块茎晚疫病的防治效果高达86.22%.
Prevention and cure potato late blight is important to safety of potato production and development of economic through Se- lecting suitable fungicide.In this experiment,useing Longsbu 3 as test materials, formulating late blight disease of potato leaves and tuber during storage grading standards, by calculating the late blight disease index and control effect, the experiment was to research and analysis eight kinds of fungicides control effect, on potato late blight such as cream ？ MnZn, Curzate, Calcium sulfate, Suppression fast net, Silver Farley, Eugenol, Baitai and Ling Guang dry.The results showed that： Eugenol control rate of Leaf potato late blight is 79.67% which better than other fungicides control effect during the field. Silver Farley control rate of Potato tube＇s late blight is 86.22% during the potato stock that better than the other fungicides.
