KILLZALL Super Concentrate - Weed and Grass Killer from Fertilome

Active Ingredient: Glyphosate

Glyphosate works by killing the photosynthesizing part of the plant above ground and working its way down to the roots. This product is harmful to people, pets, and pollinators if applied incorrectly or walked over while the product is wet. Glyphosate poses potential cancer risks to humans and animals through endocrine disruption. Use with caution. 

  • Apply with a plastic, aluminum, or stainless steel tank-type sprayer. Do not apply with galvanized or an unlined steel sprayer, through any irrigation system, or with a sprinkling can.
  • Multiple-use formulation. Use near fences, on paths, patios, sidewalks, curbs, and driveways. DO NOT USE ON LAWNS.
  • Non-selective weed and grass killer contains a double-surfactant formulation that dries on the plant fast to start working quickly.
  • 32 oz. super concentrate
