Pasture Weed Control

[Jcredeur]

Guys,
We are trying to restore a pasture back to it's glory days. Ever since the floods from Rita and Ike it seems like the grass that forms large clumps has moved in. I am not sure of what it is called, most of the old timers call it mud grass. We are looking for a way to get rid of it short of plowing the whole pasture to let the Bermuda take back over. I am at a loss as to what to spray since it does not appear to be a broadleaf. Do any of y'all have experience with this?

Thank y'all!
