Roundup Weed & Grass Killer is an herbicide used to kill most types of weeds. Although Roundup Weed & Grass Killer is a nonselective herbicide, which could kill any plant, it is considered safe to use around your flowers, vegetables and shrubs as long as you follow the manufacturer's directions.
The Monsanto Co., which manufactures Roundup, is an agricultural company that focuses on helping farmers worldwide "produce more while conserving more," according to the company's website. The company's beginnings started with John F. Queeny, who in 1901 was manufacturing saccharin. In 1960, Monsanto established the agricultural division. It commercialized Roundup herbicides in 1976. The Monsanto Co. merged with the Pharmacia Corp. in 2000. In 2007, Dr. John Franz was inducted into the National Inventors Hall of Fame for "the discovery of glyphosate." Glyphosate is the active ingredient in Roundup Weed & Grass Killer.
Although, the Monsanto Company manufactures Roundup, the Scott's Miracle-Gro Co. markets and distributes the Roundup brand. Scott's Miracle-Gro is the "world's largest marketer of branded consumer lawn and garden products," according to their website. They operate primarily in North America with businesses in Europe and Asia Pacific, as well. Their products are sold through home improvement stores, hardware stores, garden centers and nurseries. Products are also available in food and drug stores.
Roundup herbicides are available for consumer use and for commercial use. Commercial Roundup consists of two products, which are Roundup Pro-Concentrate and Roundup PROMAX. Consumer Roundup consists of three products available in premixed and concentrated formulas. They are Roundup Extended Control Weed & Grass Killer, Roundup Poison Ivy Plus Tough Brush Killer and Roundup Weed & Grass Killer. Roundup Weed & Grass Killer is available premixed, concentrated plus and super concentrated. The consumer Roundup products are available in a "Pump 'N Go" sprayer for easier application.
Roundup Weed & Grass Killer eliminates existing weeds and grass. It is guaranteed to "kill to the root," according to the Scott's Miracle-Gro website. Roundup Weed & Grass Killer contains 2 percent of the active ingredient, glyphosate. Glyphosate has a low toxicity rating, according to the Pesticide Action Network or PAN Asia & the Pacific. However, it may cause skin and eye irritation, so caution is recommended when using Roundup. The herbicide absorbs into plants' leaves and stems, where it begins killing weeds immediately.
Apply Roundup Weed & Grass Killer when weeds are actively growing. It may be used around vegetable gardens, shrubs and flowering plants. You can use it on patios, walkways and driveways. Flowers, trees and shrubs can be planted one day after using the herbicide. Fruit, vegetables, grasses and herbs can be planted three days after using the herbicide. It is rainproof within 10 minutes, according to the Scott Miracle-Gro website. Because it is absorbed through the weeds' leaves and stems, your nearby plants will not absorb the herbicide from the soil.
