- Weed foliage gradually turn yellow until total desiccation occurs.
- Initial symptoms appear in 7 - 10 days with full weed control effects appearing over 4 to 6 weeks.    **Sempra Application Rate**

  **Mixing**

- If an adjuvant is not used poor weed control will occur
- Do not apply after frosts have occurred

- Do not mow for at least 2 days after treatment to ensure optimum control
- Sempra may damage or delay establishment of newly seeded, sodded or sprigged turf that is not well established.
