通过几种药剂对马铃薯早疫病的防效比较试验,研究结果表明:从治疗效果来看75%肟菌·戊唑醇WG对马铃薯早疫病有不错的功效,对农作物的伤害几乎为0,因此这种药剂可以放心使用。使用75%肟菌·戊唑醇WG防治马铃薯早疫病的浓度以5000~6000倍为宜,在马铃薯病害前或病害初期对其进行药物防治,隔7d施药1次,在其发病比较严重的时候药剂浓度可使用5000倍液,经研究发现它的药效可持续14~30d,对比我们以前的常规用药可以节省2~3次的药量。
The results showed that the 75% tenfloxacin and tebuconazole WG had a good effect on potato early blight and the harm to crop was almost zero, so the effect of several agents on the control of potato early blight was compared. This medicine can be used with confidence. The concentration of 75% tenfloxacin and tebuconazole WG for control of early blight of potato was 5000-6000 times higher than that of the control. The disease was pretreated by potato or preliminarily, and once every 7 days, its incidence was relatively serious When the drug concentration can be used 5000 times the liquid, the study found that the efficacy of its sustainable 14 ~ 30d, compared to our previous conventional medication can save 2 to 3 doses.
