Tordon RTU Specialty Herbicide is not labeled to control willow sprouts, so we are not sure if it would be effective for this application. We do sell other products such as Fertilome Brush Killer and Stump Killer that can be used to treat willow sprouts. You would cut the stumps and apply the product undiluted to the fresh cuts.
