不同杀菌剂对马铃薯晚疫病的防治效果

Control Efficacy of Different Fungicides on Potato Late Blight

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。以‘陇薯3号’为试验材料,研究甲霜·锰锌、克露、硫酸铜钙、抑快净、丁子香酚、银法利、百泰和广枯灵8种不同杀菌剂对马铃薯晚疫病的防治效果。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%。

It is important to select suitable fungicides to effectively prevent and control potato late blight for safe potato production and economic development.Potato variety'Longshu3'was used as material in the experiment to study the control efficacy of eight different fungicides(Mancozeb,Curzate,Copper Calcium sulphate,Equation-pro,Eugenol,Infinito,Baitai,and Guangkuling)on potato late blight.In the field,eugenol had the best control effect,being as high as79.67%;in storage,the control effect of infinito was up to86.22%.
