I want to kill crabgrass
Q4 Plus Turf Herbicide is labeled safe to use on a variety of grass species, however you will need to check the Product Label for your grass type before purchasing or applying the Q4 to make sure you have a tolerant species. Q4 Plus is great for controlling crabgrass and a wide variety of other weeds such as nutsedge, clover, wild violet, etc.
