The application of herbicides in cornfields to achieve the desired results must be noted.
How to use cornfield herbicides?
1. Quantitative application: Whether spraying or toxic soil, the quantitative agent should be sprayed evenly on the entire grass to be weeded, without leakage or weight, to ensure the quality of application.
2. The ground should be flat and fine: only when the ground is flat and fine, the tight layer that blocks the weeds can be formed.
3. Pay attention to the application time: According to the herbicidal mechanism of herbicides, strictly control the application time.
4. Pay attention to the soil environment at the time of application: the herbicidal effect of the herbicide has a great relationship with the humidity of the soil, and the drug is easily diffused when the soil is wet. The low moisture content of the soil is poor in herbicidal effect. The texture of the soil also has an effect on the herbicidal effect. The adsorption of the sandy soil on the medicine is poor, and the application amount should be strictly controlled.
5. Protection of the drug layer: After spraying the herbicide in the corn field, do not go to the field for other operations to destroy the drug layer and reduce the herbicidal effect.
6. Pay attention to safety: Herbicides are irritating to people, livestock and poultry, and harmful to fish and shrimp. They should be standardized when applying drugs to prevent pollution.
