Answer:

While Certainty Herbicide is labeled to treat Poa Annua, it will also kill your Fescue lawn. Instead, you could use Bensumec 4LF on Fescue turf. Bensumec 4LF is a pre-emergent broadleaf herbicide that provides season-long control of broadleaf weeds in all major turf grasses, including Fescue.
