Coliseum Herbicide has very good root uptake and can be washed in just one hour after application, which greatly reduces the chance of tracking and damage to non-target areas. Irrigation should be applied prior to foot traffic the following morning as sulfonylureas can reactivate with heavy dews. The irrigation cycles are short to ensure the product is washed off the leave and to enhance root uptake.
