Pyrazosulfuron-Ethyl 75%WDG 10%WP 100g/L SC

Application

1. 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.
2. 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.
3. 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.
4. 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.
5. Key considerations include selecting the appropriate application timing, avoiding use on sensitive crops or varieties, and maintaining proper water levels to improve efficacy.
6. The application of pyrazosulfuron-Ethyl may harm surrounding broadleaf crops, so caution is warranted during use.
7. 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.
8. To ensure optimal results, maintain water levels for at least 5 days after application in transplanted fields.
