Things You'll Need
The active ingredients in Eliminator Weed & Grass Killer Super Concentrate are glyphosate and isopropylamine salt. The manufacturer says the formula is able to kill all annual and perennial broadleaf and grassy weeds. The herbicide is labeled for use in flowerbeds, around shrubs and trees, on driveways and walkways, and along fences. The maker also states that the herbicide does not move in the soil; therefore, it kills only the plants you spray. Any residue that hits the ground breaks down into natural substances. Since this is a concentrated formula, you'll need to dilute it before you use it.
