Before planting cotton, choosing the right herbicide is essential to control weeds effectively. According to the China Pesticide Network, several herbicides are suitable for pre-emergence weed control in cotton fields. These include trifluralin, lasso, acetochlor, butachlor, diuron, and pendimethalin. For post-emergence weed management, you can use herbicides like glyphosate, paraquat, or clethodim, which are effective on both grassy and broadleaf weeds.
For pre-planting application, you can spray 100–150 ml of 48% trifluralin emulsifiable concentrate per mu (approximately 667 square meters) mixed with 50 kg of water. This should be done evenly over the soil surface before planting. Another option is to use 200–300 ml of 43% pendimethalin emulsifiable concentrate per acre, also diluted in 50 kg of water. It’s important to apply these herbicides uniformly to ensure maximum effectiveness.
Once the cotton plants have developed four true leaves, you can apply a foliar herbicide such as 50 ml of 50% clethodim emulsifiable concentrate or 50 ml of 12.5% glyphosate emulsifiable concentrate mixed with 50 kg of water. This helps control weeds that have already emerged without harming the young cotton plants.
When using herbicides in cotton fields, there are several key points to keep in mind: First, always choose the herbicide that is appropriate for the type of weeds you're targeting. Second, make sure to measure the dosage accurately to avoid under or over-application. Third, consider environmental factors such as temperature, soil moisture, and humidity when applying. Always follow the manufacturer's instructions carefully. Lastly, it’s best to use dedicated equipment for herbicide application to prevent cross-contamination with other pesticides or fertilizers.
By following these guidelines, you can effectively manage weeds in your cotton field while minimizing risks to the crop and the environment.
