Will Tenacity damage Poa trivialis lawngrass?

I have Poa Triv in shady areas and need to get rid of invasive creeping bent in my lawn.

Answer:

The product label for Tenacity does not specify whether it would harm poa trivialis. Both bentgrass and poa annua may be sensitive to Tenacity, while Kentucky Bluegrass is listed as tolerant. Certainty Herbicide is labeled to control poa trivialis, but we are not certain if it would harm the bentgrass. The best option for you is to spot treat the rough bluegrass with RoundUp QuickPro and then reseed with the desirable turfgrass.
