If you need to control field sandbur in Bermuda turfgrass, then we recommend using Image Kills Nutsedge.

If any discoloration or cosmetic effects are objectional or would be unacceptable then the use of a surfactant would not be recommended. The product label does not mention any issues with hard water.
