Glufosinate-ammonium herbicide is a commonly used broad-spectrum herbicide, and its mechanism of action is to interfere with the tricarboxylic acid cycle in plants by inhibiting the activity of glutamate decarboxylase in plants, resulting in plant growth arrest, leaf yellowing and shedding, and eventual death. The following are the methods and precautions for the use of glufosinate-ammonium herbicides:
How to use:
Spray method: Add glufosinate-ammonium herbicide to the sprayer according to the prescribed dose, dilute it with water and spray. When spraying, cover the leaves of the target weed evenly and ensure that the solution can reach the roots of the weed. For some tall weeds, directional spraying can be used to spray the liquid medicine to the lower part of the weeds.
Smearing: For some stubborn weeds, you can use the smearing method. This is done by applying glufosinate-ammonium herbicide to the stems of the weed, or by pouring the solution directly into the roots of the weed. When applying, make sure that the solution completely covers the stems of the weeds and penetrates into the roots.
Precautions
Security protection: Glufosinate-ammonium herbicide has a certain toxicity, and protective clothing, gloves, masks and other protective equipment should be worn when using. Avoid direct contact with the liquid medicine** and eyes, and rinse with water immediately if it accidentally comes into contact with ** or eyes.
Time of use: It is best to apply the pesticide in windless weather to avoid the liquid spreading to areas that do not need weeding. It is best to choose the application time in the vigorous growth period of weeds, when the weeds have the strongest absorption and transportation capacity of herbicides, and the weeding effect is better.
Dosage vs. concentration: When using glufosinate-ammonium herbicide, it should be diluted according to the specified dose and concentration, and the dosage or dilution ratio should not be increased or reduced at will. Excessive use of herbicides can lead to environmental pollution and the development of weeds to become resistant.
Soil and climatic conditions: Soil moisture and climatic conditions can also affect the effectiveness of glufosinate-ammonium herbicides. When the soil is moist, it is conducive to the absorption and transportation of chemical solutions, while unfavorable climatic conditions such as high temperature, drought and rainfall may reduce the weeding effect.
Post-crop crops: After the application of glufosinate-ammonium herbicide, it should be ensured that the solution does not affect the subsequent crops. According to different crop and soil conditions, the pesticide application time and the planting time of the stubble crop should be reasonably arranged.
Storage & Transportation: Glufosinate-ammonium herbicide should be stored in a cool, dry and ventilated place, away from fire and heat sources. Attention should be paid to safety during transportation to prevent leakage and contamination.
Environmentally friendly: When using glufosinate-ammonium herbicides, the principle of "green plant protection" should be followed to minimize environmental pollution and ecological damage. The rational use of herbicides is conducive to the sustainable development of agricultural production and ecological environment.
In conclusion, the correct use of glufosinate-ammonium herbicides requires attention to safety protection, application time, dosage and concentration, soil and climatic conditions, stubble crops, storage and transportation, and environmental friendliness. Only by taking into account a combination of factors can the full effect of herbicides be fully utilized while reducing the negative impact on the environment and crops.
