Pre-e will help somewhat but timing is everything. I use it in August for
poa control here in northern Ohio. You have to be careful to stay away
from
bentgrass with it, and not to apply too much for fear of root pruning on
your desirable turfgrass.

You have to apply it after the poa dies back and before it re-germinates,
which is generally late summer.
