Some pesticide herbicides are generally a high-efficiency, broad-spectrum herbicide, suitable for weed control in fields such as rice and corn. Here's how to use pesticide herbicides:
1.Dilution preparation: Mix the pesticide herbicide with an appropriate amount of water according to the instructions on the package, and stir well.
2.Spraying time: Spraying is carried out during the vigorous growth period of weeds, generally 10-15 days after transplanting rice, when weeds grow 3-5 leaves.
3.Spraying method: Choose sunny and windless weather and use a sprayer or spray gun to spray evenly. When spraying, avoid spraying directly on the rice plants to avoid causing damage to the rice.
4.Dosage: According to the type and density of weeds, the dosage on the package is prepared. In general, 100-150 ml of quantitative herbicide per mu is required.
5.Precautions: When using some pesticide herbicides, pay attention to the following:
Read the instructions carefully before spraying to understand the dosage and precautions.
When spraying, choose sunny and windless weather to avoid wind and rain weather affecting the efficacy of the drug.
When spraying, avoid spraying directly on the rice plants to avoid causing damage to the rice.
After use, the sprayer or spray gun should be cleaned in time to avoid residual drugs causing harm to other crops.
In conclusion, the use of broad-spectrum pesticide herbicides is a highly effective and low-toxicity herbicide, which is suitable for weed control in rice fields and other fields. When using, it is necessary to pay attention to the dosage and precautions to ensure the efficacy and safety of rice.
