Control: Turfgrass

For centipedegrass, St. Augustinegrass, zoysiagrass, and dormant bermudagrass, Atrazine is labeled as a preemergence and postemergence control. Apply in early spring after green-up for summer control. Do not apply atrazine to unestablished sod, during greenup, to root zones of ornamentals,or to any cool season grass. Image or imazaquin can be used postemergence on the grasses listed above. Do not apply image to turfgrass during spring greenup or to newly planted grass. Manor (metsulfuron) provides good control on the grasses listed above. 2,4-D + MCPP + dicamba, which is Weed-B-Gon Lawn Weed Killer 2 or Ace Lawn Weed Killer, can be used on the above grasses but use half rates and spot treatments to minimize damage to Centipedegrass and St. Augustinegrass.
