There are certain bio types of crabgrass in California that are resistant to quinclorac, the active ingredient in Drive XLR8. There are a number of options that can be looked at to obtain control of resistant crabgrass. Give us a call at 800-476-3368 and a turf specialist can help troubleshoot the issue.
