Allan from Portland, Oregon writes

Is there any benefit to ProGrass over Tenacity as a pre-emergent against poa annua on perennial rye?

I live in Oregon and have primarily perrenial rye with some fescue.


Tenacity is only going to suppress poa annua when used as a pre-emergent for it. You would really only use Tenacity as a pre-emergent over the entire lawn if you are needing a pre-emergent to use at the same time as seeding or over-seeding. Otherwise, ProGrass would be a better choice for poa annua control and for use on established perennial ryegrass.
