A herbicide is often only effective against one or several weeds, and in the field, multiple weeds are often present at the same time, and weed control cannot be controlled with only one herbicide. If you choose a combination of several effective herbicides for the type of weeds in the field, most weeds can be controlled. For example, if weeding ether is used alone in rice fields, it can not control the ragweed and the geranium, but the herbicide ether can be controlled by mixing with 2,4,4 chlorine. When the herbicide or the herbicide is used alone, it can effectively control the psyllium and the geranium. However, it cannot prevent broadleaf weeds and algae, but it can be used in combination with Xicaojing. Both of them can be treated with mixed preparations, such as Chuan'an Paibao (36% benzyl dichloride mixture). effect.
The combination of herbicides can also reduce the impact on the crops. For example, wilt is used in corn fields to control weeds. It is very safe for corn and good for weed control. However, it is not possible to sow sensitive crops. Seriously, if alachlor is used in combination with wilfordine to reduce the amount of wilting to 3/4, the herbicidal effect of the corn field can be ensured, and the impact on the sorghum crop is greatly reduced.
