Chris,
Regrassed our greens in fall of 2011, last year was the first season with them (A1/A4). Mid June last year we began using PGR's on them to help slow top growth, lot of built up fert and lots of growth. Nothing was really to prevent Poa, is there such a thing. Our method to prevent or control any Poa that showed up was to remove manually by plugging it out or cutting it out with a knife. This fall we did apply Bensumec, labeled as a preemergent for Poa. Last season we were using Cutless/Primo applications and going basically 6oz each per acre. Started using Cutless as found it was easier on the bluegrass surrounds. This year I have gone back to Trimmit as we purchased a GPS sprayer that helps eliminate the overspray and I feel the Paclo does a bit more on the Poa, going at 8oz/Acre currently and seeing good success.
