Vince from Downingtown, Pa writes

Can Certainty be used on cool season grass?

I have poa triv that I want to eliminate. From what I read, this is the best for it but label mention only warm season grass.

Answer:

Certainty can only be used on warm season turf.  Unfortunately, since poa trivialis is also a cool season grass, there is not a selective herbicide that would kill the poa trivialis without also killing the desirable turf. We suggest spot treating with a non-selective Roundup-type product, and then reseeding in a couple of weeks.
