Application Instructions
1. Mixing
This product is a Suspo-Emulsion (SE). Shake the bottle vigorously before use. Pre-mix the required quantity in a bucket of water to form a uniform slurry, then pour into the main tank while agitating.
2. Timing of Application
Apply as a post-emergence spray. For transplanted rice, drain the field before application and re-flood 2-3 days later to suppress weed re-growth.
Safety Precautions
Warning: Wear protective gear including gloves, mask, and boots. Do not drain treated water into fish ponds as herbicides may be toxic to aquatic life. Wash hands thoroughly after handling.
