    Hey guys, I need some info... I picked up a lawn a bit late this season that is all Zoysia, sodded last year. I did a pre and post application on it with Surflan and Trimec 992. The lawn was already coming out of dormancy, so I didnt include an Glyphosate in the mix. I got all the broadleaf weeds (and there were a ton of them), but now she's got quite a bit of Poa Annua, and lots of Crabgrass coming up in the back yard. Suprisingly, the entire front yard is clean. My chemical rep says I'm pretty much SOL until fall, unless I want to use Diquat, but then I will run the risk of knocking back the Zoysia. I know I could use Dimension and knock out the Crabgrass, but I dont think it will take care of the Poa. Any ideas, or am I just gonna have to wait til fall?

    Revolver is labelled for PA in zoysia. The crab is still tillering, then?
