八种杀菌剂对马铃薯晚疫病的防治效果

摘要

Eight kinds of fungicides were evaluated for their control efficiency to potato late blight. The results indicated that 4 different fungicides, Dimethomorph, Equation-pm, Infinito and Cymoxanil mancozeb, showed over 60％ of the disease control efficiency after 8 of the application, which led to a yield of 145％ higher than the control treated with water. Effect of anti-infection for plants was higher than the chemical treatments of other fungicides such as Baitai, Baoling, Wangtong and Lvmu.%选用8种杀菌剂对马铃薯晚疫病进行防治效果研究.结果表明,安克、银法利、抑快净、克露4种药剂处理在第一、二次施药后8 d调查防治效果均在60%以上,较清水对照增产145%以上.百泰、宝灵、王铜、绿沐处理防治效果较差,增产幅度不大.
