Echelon 4SC is not specifically labeled for sandburs. We recommend Image 70 DG to treat sandbur. Also, to prevent them for next year, you should apply Barricade or Surflan AS as a pre-emergent. It will control sandburs in your yard, as well as a multitude of other broadleaf weeds. It is highly recommended that you refer to the product labels prior to purchase to make sure your lawn type is listed under grass species that are tolerant to the product.
