Is Roundup effective on established crabgrass? I want to stop it before it gets too out of control.
Roundup Pro Max will kill just about anything that it is applied to so it will kill crabgrass but will also kill your lawn if that is where you are spraying it. Our most popular crabgrass product is Drive XLR8. Drive XLR8 Herbicide is the latest technology in providing unsurpassed post-emergent crabgrass control. Drive XLR8 is a post emergent selective herbicide that is labeled for crabgrass as well many other troublesome weeds. Not for use on St Augustine grass. Please refer to the product label to ensure your grass type is tolerant to the Drive
