Monterey Spurge Power is not labeled for sandbur nor will it prevent new weeds from germination from seed. For Warm Season lawns, a post emergent such as Image Kills Nutsedge or Celsius WG can be used when the weeds are actively growing. For Cool Season lawns, we would recommend Acclaim Extra Herbicide along with a Non Ionic Surfactant for sandbur when it is actively growing. We recommend using a pre-emergent for field sandbur in the fall, such as Pendulum 2G or Dimension 2EW:Granule.
