Image Herbicide for St. Augustine Grass and Centipede Grass Concentrate was discontinued by the manufacturer many years ago; however this product contained Atrazine and was labeled for control of sandbur. If you have St. Augustine or Centipede and need to control sandbur, then you may consider Hi-Yield Atrazine instead.
