What can I use to get rid of poa trivialis in a Kentucky bluegrass/fine fescue lawn?

Answer:

Unfortunately, since poa trivialis, fescue, and Kentucky bluegrass are all cool season grasses, there is not a selective herbicide that would kill the poa trivialis without also killing the other grasses. We suggest spot treating with a non-selective like Roundup and then reseeding after 2 weeks.
