How to Use Nicosulfuron Herbicide
Nicosulfuron is an excellent herbicide commonly used in corn cultivation. Many farmers purchase corn-specific herbicides like Nicosulfuron. Let's take a closer look at how to use Nicosulfuron herbicide effectively.
Methods of Using Nicosulfuron Herbicide
Step 1: Application Timing
Nicosulfuron is used for post-emergence weed control. The optimal time for application is during the 3-5 leaf stage of corn. Under normal circumstances, weeds are in the 2-4 leaf stage during this period. The more weeds that have emerged in the field, the better. Weeds are less resistant at the 2-4 leaf stage, increasing the effectiveness of the herbicide.
Step 2: Target Weeds
Nicosulfuron is a broad-spectrum herbicide that effectively controls annual weeds in corn fields, such as barnyardgrass, crabgrass, goosegrass, ryegrass, purslane, and others.
Step 3: Dosage
For controlling annual weeds in corn fields, use Nicosulfuron at a rate of 55-65 milliliters per acre, applied as a foliar spray. Dilute with 30 kilograms of water for application. Avoid using tap water for dilution.
Precautions When Using Nicosulfuron Herbicide
1. Weather and Wind Conditions
When applying Nicosulfuron, pay attention to wind direction and weather conditions to prevent the herbicide from drifting to non-target areas.
2. Personal Protective Equipment
Wear appropriate protective gear, such as gloves, masks, and protective clothing, to avoid contact with skin and eyes. If accidental contact occurs, rinse immediately with clean water.
3. Application Technique
Evenly spray the prepared herbicide solution on the weeds in the field, avoiding contact with the crop plants.
4. Long-Lasting Effect
Nicosulfuron has a long-lasting effect. Do not arbitrarily increase the dosage to avoid phytotoxicity to sensitive crops in subsequent planting seasons.
5. Mixing with Other Pesticides
Do not mix Nicosulfuron with organophosphorus pesticides.
6. Soil and Weather Conditions
Avoid using Nicosulfuron in high-temperature, drought conditions, low temperatures with heavy rain, or waterlogged fields to prevent phytotoxicity.
7. Frequency of Use
Use Nicosulfuron only once per season to prevent increased herbicide residue in the soil.
8. Optimal Application Time
Apply Nicosulfuron in the afternoon when temperatures are lower or in the morning after dew has dried. If it rains within 4 hours after spraying, reapply at a lower concentration.
Conclusion
The above information provides a detailed guide on how to use Nicosulfuron herbicide. While Nicosulfuron is effective in controlling annual weeds in corn fields, it is crucial to follow the precautions to ensure its safe and effective use.
