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.
