Tenacity Herbicide is labeled for post emergent control of actively growing lawn burweed (spurweed, stickerweed, sandbur, sanbur, and sandspur) but will not offer any pre emergent control to prevent sandbur from germinating. When using Tenacity for post emergent control of weeds, a Non Ionic Surfactant is needed. View the full list of Weeds Controlled (Pre & Post Emergent) on page 9 of the product label.
