Made with natural ingredients, BurnOut is safe for use around people and pets when used as directed. BurnOut kills all types of actively growing weeds and grasses. BurnOut is very fast acting, is rainproof when dry, works at temps as low as 40 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 safe, effective, non-selective weed control is desired.
