Bob from Ann Arbor Michigan writes

Will Tenacity Herbicide kill yarrow?

Answer:

Tenacity Herbicide is not labeled for yarrow. This weed can be difficult to get rid of especially if the rhizomes are not fully removed which you would need to dig down about 12 inches. Consider using Q4 Plus which is labeled for yarrow. Please refer to the product label to ensure your desired turfgrass species is tolerable.
