I'm up in NE Oklahoma where we don't see Staugustine too often. It's my first. Around here we use Simazine and Three Way for our fall treatments on warm season grass with excellent results. I'm getting conflicting answers when asking around what broadleaf control I can use. Lesco rep says to use my normal Simazine/Three way mix and I didn't think Staugustine could take 2,4D. He said I'll get a little yellowing which would be ok since the color it turning anyways in Oct. Thanks for any advise.
