Made with natural ingredients, BurnOut® is approved for organic gardening, and is safe for use around people and pets. 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. Always read and follow label directions.
