    Anyone spray poa triv with Certainty in tall fescue this year? What result did you have and are you going to reseed this fall or preem in the fall and seed in the spring? I just sprayed two weeks ago and I have a good kill on the poa triv but may have also damaged some of the tall fescue? I sprayed between .25 to .5 ounces per acre. Anyone have any thoughts, opinions, or suggestions? Thanks.

    You should not even think about using Certainty on tall fescue--it is not labelled for use on it. Try ethofumesate on poa trivialis instead.
