Is Certainty Herbicide - 1.25 oz. a good product to kill poa annua in TTTF?

Or is there so such thing available?

Answer:

While, Certainty Herbicide is labeled to treat Poa Annua, it will also kill your Fescue lawn.  There are few products that we are aware of that will kill the poa annua without also harming the fescue. The only ones we are currently aware of are called Prograss or Xonerate which are both very expensive. Your other options would be to either spot-treat with a Roundup-type product and then reseed with the fescue in those areas, or you can use a preemergent such as Pendulum in the fall to prevent the poa from growing in the first place
