    Roundup and reseed. They have products like Pro Grass etc that claim to kill poa but I believe most also attack rye and some fescues.

    Plus it's expensive as heck. Roundup machine seed done. Cheap, available product and easy.

    From what I've heard Poa control requires a consistent pre-M app. a few times per year, has anyone used an effective Post type control of Poa to kill off whats existing??

    you might wanna try certainty, i believe it's labeled for it along with a host of other things...does stunt good grasses , though. Be careful...

    I have seen good results with Tenacity Hebicide, but it does take a couple of weeks.

    Tenacity says Suppresion as a Pre-M and NO for Post-em on Poa, and Certainty is listed for Warm Season turf, and we have almost exclusively Cool Season Perennial Ryegrass here in Southern Oregon, so maybe I just need to call my local Pesticide Dealer and see what they recommend....
