How do I kill tall fescue in a KBG lawn?

I thought I was going to be able to use Certainty to kill the tall fescue in my KBG lawn until I read the note on the label change after 2011. What is the right product to use now?

Answer:

We do not carry a product that will take fescue out of kentucky blue grass.  Unfortunately they are so closely related that you cannot selectively remove it with any product that we are aware of.  Your best option in this scenario is to kill the fescue with a Ranger Pro (glyphosate) product and then re-seed with your KBG.
