Scott from Pittsburgh, Pa writes

Will Certainty kill Poa Trivialis present on my primarily Bluegrass lawn?

Without killing the grass. If not any suggestions

Answer:

Certainty Herbicide - 1.25 oz. cannot be used in cool season grasses and will harm them.  We are not aware of any product labeled to control poa trivialis in a bluegrass lawn.  In your case it would be best to spot treat the poa with a glyphosate based product such as GlyPhoSel Pro and reseed the area.
