Application Tips for Success

  • Apply Viewpoint® to huisache in non-crop sites at a rate of 16 to 20 ounces per acre in the fall. Do not apply more than 20 ounces per acre per year.
  • If sensitivity to desirable grasses on a right of way is a concern, apply DuPont™ Streamline® herbicide to huisache at a rate of 9.5 to 11.5 ounces per acre when brush plants are actively growing. Do not apply more than 11.5 ounces per acre per year.
  • Use sufficient water volume to ensure thorough foliage coverage.
  • For best results, treat huisache before brush gets too tall or too dense for adequate foliage coverage.
  • Viewpoint® is registered for non-crop use only. Do not graze or feed forage, hay or straw from treated areas to livestock.

Viewpoint® also controls ash, boxelder, hackberry, maple, mesquite and other hard-to-control brush.
