| Cycle: |
|
| Management: |
- Read and follow all label directions.
- Use caution when applying herbicides around plants as desirable plants may be sensitive and injury may result.
- Do not spray during cool, wet weather as herbicide is metabolized slower at these times.
- Do not spray when wind speed and direction are such that herbicide drift is likely to occur.
- Affected plants may or may not survive herbicide drift; it depends on both the degree of exposure and the plant's tolerance to the herbicide.
- Water and fertilize plants as needed to promote good plant health.
