Mel:
It's best to use Gallery 75 for your pre-em. Then follow up with metsurfuron. Both of these are friends to the St. Augustine. It may be a little difficult to control them now; the best control is way before they begin to set a stalk. Atrazine would be a good choice in the very early spring for any that pop up really early. Manor or "Mansion" from Lesco is a metsurfuron brand name. Also, check out E-Bay.
Read the label on the metsurfuron.

Look into the pyridine and sulfonlurea chems.
