I've investigated this for some time now......if the lawn is centipede or St. Aug, there is nothing you can do.
Choices are, dig up each clump of crabgrass and sod immediately or burn the lawn and start over.
Seriously. I am crazy about my lawn, started to get a couple of patches of crabgrass a few years ago. I called the LSU ag department and the composition of centipede and st. aug is so close to crabgrass that anything you spray will kill the grass too.
The only way to defeat crabgrass is to keep your lawn healthy and never let it take hold. Crabgrass comes in when you have an unhealthy lawn.

those professional lawn services literally come out there and brush paint it with round up OVER and OVER. The problem is that its got so many seeds, so you kill the active stuff, then the seeds bring it right back up. Digging it up w/ do it quicker, but painted round up over and over will do it too.
