Image 70 DG herbicide is a selective postemergent herbicide that overpowers stubborn weeds in warm-season turfgrasses that other herbicides just can't control. Absorbed through the root systems of targeted weeds, Image inhibits the enzymes needed for photosynthesis so food production stops and weeds waste away. When used as directed, Image:Controls many "uncontrollable" weeds including purple and yellow nutsedge, field sandbur, dollarweed and green kyllinga. Can be used on established warm-season grasses, such as bermudagrass, centipedegrass, St. Augustinegrass and zoysiagrass, as well as many landscape ornamentals and ground covers.
