Johnson's recommends Image Ready-to-Spray Herbicide to control nutgrass. Nutgrass looks like a grass, but it's actually a sedge, which can be tough to control. Using a patented ingredient to starve select weeds to death, Image Herbicide targets yellow and purple nutsedge, dollar weed, poa annua, wild onion, sandspur, and annual blue grass. A hose-end applicator makes it easy to apply. Labeled for use in warm-season turf grass (zoysia, bermuda, and buffalograss) and selected ornamentals. Not for use on cool season grasses such as fescue. Always read and follow package instructions. Treats 8000 sq. ft. 32 fl. oz.
