Tordon RTU Specialty Herbicide is not labeled to control Wisteria, so we do not recommend it for this application. Keep in mind, too, that Tordon is not approved for use on residential properties at all. You could use a brush killer such as Crossbow or Fertilome Brush and Stump Killer to control wisteria vines.
