PCP - try about 0.5 oz/A of Escort. It should give you good control of most of your broadleaf weeds, particularly if you add it to the 2,4-DB. I know it does not have much, if any, nutsedge activity, so should be okay on your chufa. Test a small patch first. Weed control information in the food plot arena is sorely lacking. I have been trying to drum up some research monies to do some of this type work but it just isn't there.
