best pre-emergent for Poa Annua?
I gather it is early yet, but since so many of us (particularly the Fall '07 renovators) seem to be blighted with the stuff, I am wondering: what is the best pre-emergent for Poa Annua in the typical high-mowed, homeowner-maintained KBG yard? I have searched and searched, but keep turning up studies on overseeded Bermuda and Bentgrass golf fairways and greens. Obviously many of the problems faced by those turf managers don't confront most of us.
So which Pre-emergent is best for us?
Any and all thoughts appreciated.
