Application
- Pyrazosulfuron-Ethyl can be used to control various weeds in direct-seeded, transplanted, and broadcast-seeded rice fields, including both annual and perennial broadleaf weeds as well as sedges, such as Cyperus esculentus, water nutgrass, purple nutsedge, and funds.
- For barnyard grass beyond the 2-leaf stage, pyrazosulfuron-Ethyl alone shows poor efficacy and is typically used in combination with other herbicides to enhance weed control.
- The timing for application in seedling and direct-seeded rice fields is during the 1-3 leaf stages of rice, whereas for transplanted rice, it should be applied 3-20 days after transplanting. In dry direct-seeded fields, applications are made during the 1-3 leaf stages of rice, maintaining the appropriate water levels.
- Application methods for pyrazosulfuron-Ethyl include mixing with soil for broadcasting or dilution with water for spraying. The specific dosage may vary based on different crops and weed situations.
- Key considerations include selecting the appropriate application timing, avoiding use on sensitive crops or varieties, and maintaining proper water levels to improve efficacy.
- The application of pyrazosulfuron-Ethyl may harm surrounding broadleaf crops, so caution is warranted during use.
- Different crops exhibit varying degrees of tolerance to pyrazosulfuron-Ethyl, so appropriate dosages and methods should be determined based on local conditions and crop types.
- To ensure optimal results, maintain water levels for at least 5 days after application in transplanted fields.
