Bermuda grass growers what is your herbicide program?

I am trying to figure out a good herbicide program for my irrigated Bermuda grass field. The last few years I have started to get a little crab grass in my field this year 1st cutting was ok but now it has gotten pretty bad. So trying to figure out a plan of attack next year as I think it may be a little to late this year to do anything. In years past I have use 4qts of prowell h20 in early spring and it has worked ok for 1st and 2nd cutting but not great. I’m just trying to find out you guys with the Beautiful weed / grass free Bermuda fields what are you doing to get and keep it that way way. Thank you.
