Unfortunately, the Dismiss Turf Herbicide is not labeled to treat for crabgrass. Drive XLR8 is an excellent post-emergent herbicide to kill existing crabgrass. It is safe to use on most types of turf, but not all. Please refer to the product label for indications on what turf this may be applied to.
