Drive XLR8 Herbicide Crabgrass Killer is designed to treat crabgrass and other listed weeds, primarily in approved turf areas. The product label does not list mazus ground cover as a tolerant species of plant. However, since this product does kill a variety of broadleaf weeds, it may injure your groundcover. You may want to contact a master gardener in your area through your Cooperative Extension Service if you are having trouble finding an herbicide that will meet your needs.
