Made from natural ingredients, BurnOut® is safe for use around people and pets. BurnOut kills all types of actively growing weeds and grasses. It's rainproof once dry, works at temperatures as low as 40 degrees F. and does not translocate. Great for use around borders, driveways, sidewalks, around the base of mature trees, around buildings, fence lines, barns and pastures, school grounds, in greenhouses, and other areas where weed control is desired. Non-selective control of herbaceous broadleaf and grassy weeds. Concentrate; mix one part BurnOut to three parts water and spray on weeds to the point of run-off.
