To kill weeds, especially annual broadleaf weeds and grasses known to compete with commercial crops grown around the globe.
In addition to its use as an herbicide, glyphosate is also used for crop desiccation (siccation) to increase harvest yield and, as a result of desiccation, to increase sucrose concentration in sugarcane before harvest. The half-life of glyphosate in soil ranges between 2 and 197 days; a typical field half-life of 47 days has been suggested. Soil and climate conditions affect glyphosate's persistence in soil. The median half-life of glyphosate in water varies from a few to 91 days. Herbicide(s) , also commonly known as weedkillers, are pesticides used to kill unwanted plants. Selective herbicides kill specific targets, while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often synthetic mimics of natural plant hormones.  Glyphosate is an herbicide. It is applied to the leaves of plants to kill both broadleaf plants and grasses. The sodium salt form of glyphosate is used to regulate plant growth and ripen fruit. Glyphosate was first registered for use in the U.S. in 1974. Glyphosate is one of the most widely used herbicides in the United States. People apply it in agriculture and forestry, on lawns and gardens, and for weeds in industrial areas. Some products containing glyphosate control aquatic plants Some crops have been genetically engineered to be tolerant of glyphosate (i.e., Roundup Ready, also created by Monsanto Company). Such crops allow farmers to use glyphosate as a postemergence herbicide against weeds, but the development of glyphosate resistance in some weed species is emerging as a costly problem. The half-life of glyphosate in soil ranges between 2 and 197 days; a typical field half-life of 47 days has been suggested. Soil and climate conditions affect glyphosate's persistence in soil. The median half-life of glyphosate in water varies from a few to 91 days. Glyphosate, Roundup’s active ingredient, is the most widely used herbicide in the United States. About 100 million pounds are applied to U.S. farms and lawns every year, according to the EPA. Until now, most health studies have focused on the safety of glyphosate, rather than the mixture of ingredients found in Roundup. The EPA considers glyphosate to have low toxicity when used at the recommended doses. “Risk estimates for glyphosate were well below the level of concern,” said EPA spokesman Dale Kemery. The EPA classifies glyphosate as a Group E chemical, which means there is strong evidence that it does not cause cancer in humans. GLYPHOSATE. Glyphosate is the active chemical ingredient in Roundup herbicide as well as many other name brand glyphosate-based weedkillers. These herbicides are the most widely used in the world and their use has increased exponentially with the introduction of Genetically Engineered (GMO) crops. There are 3 patents on glyphosate: It was first patented in 1964 by Stauffer Chemical as a metal chelator that was used to clean or descale commercial boilers and pipes (2). Glyphosate binds to and removes minerals such as calcium, magnesium, manganese, copper and zinc that are vital to our health. Glyphosate is a non-selective herbicide, meaning it will kill most plants. It prevents the plants from making certain proteins that are needed for plant growth. Glyphosate stops a specific enzyme pathway, the shikimic acid pathway. It is applied to the leaves of plants to kill both broadleaf plants and grasses. The sodium salt form of glyphosate is used to regulate plant growth and ripen fruit. Glyphosate was first registered for use in the U.S. in 1974. Glyphosate is one of the most widely used herbicides in the United States. For example, chemicals known as surfactants are used to increase glyphosate’s ability to penetrate into plant cells. The exact combination of chemicals used in any herbicide is a commercial secret. In fact, only glyphosate, which is called the ‘active ingredient’, has to be listed on the product label. Glyphosate is not used in its pure form in herbicide formulations. Firstly, it is combined with an alkali, creating a salt. Commonly used alkalis include ammonium, trimethylsulphonium (trimesium) and isopropyl-ammonium (IPA), a chemical used in dye manufacture. Glyphosate (N -(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf weeds and grasses known to compete with commercial crops grown around the globe. The half-life of glyphosate in soil ranges between 2 and 197 days; a typical field half-life of 47 days has been suggested. Soil and climate conditions affect glyphosate's persistence in soil. The median half-life of glyphosate in water varies from a few to 91 days. Despite the fact that glyphosate is the world´s best-selling chemical herbicide and glyphosate-containing herbicides are the most widely-used herbicides in Europe, very little testing is done for glyphosate residues in food, feed, or water. Tests for glyphosate in the body do not take place at all. Glyphosate is not used in its pure form in herbicide formulations. Firstly, it is combined with an alkali, creating a salt. Commonly used alkalis include ammonium, trimethylsulphonium (trimesium) and isopropyl-ammonium (IPA), a chemical used in dye manufacture.
