棉花栽培茎叶除草剂筛选试验

Screening Test of Herbicide in Cotton Stems and Leaves

为了降低棉花生产除草的工作量,选择田间生产常见的5种苗后茎叶除草剂进行田间防效对比试验,通过对比不同药剂的防治效果,筛选出安全、高效的茎叶除草剂。结果表明,敌草快使用安全、高效,其他药剂防效较好,但安全性低,不宜在棉花生产中使用。

The aim was to reduce the workload of weeding in cotton production,5 kinds of post-seedling stalk and leaf herbicides commonly produced in the field were selected for field control efficiency comparison.The results showed that 25%high efficiency cyhalothrin and acetamidine emulsion was safe and efficient to use,while other agents had better control effect,but the safety was low,and it was not suitable in cotton production.
