Tall Fescue in Lawn

[David Frank]

I recently had an estimate prepared for our lawn by a lawn care company, and found out that what I thought was crab grass or quack grass, is actually tall fescue. It seems to be spreading through our lawn, and according to the company that looked at it, there is no control option available without killing the entire lawn and re-seeding. I did some research, and have read that Certainty may be effective in eliminating tall fescue without harming the lawn. Anybody have any experience with this, or any other suggestions?

Thanks!!
