Anwendungen & Verwendung
Beschreibung
Glyphosate (N-(phosphonomethyl)glycine; 1071-83-6) is the active ingredient in several commercial herbicides for nonselective weed control. Glyphosate herbicides are among the world’s most widely used herbicides. Roundup, containing the active ingredient glyphosate, was developed and introduced by Monsanto Company in 1974. Other formulations include WeatherMax, UltraMAX, Buccaneer, Razor Pro, Rodeo, and AquaMaster. Some crops such as soybeans and cotton have been genetically engineered to be resistant to glyphosate (Roundup Ready), allowing farmers to use glyphosate as a postemergence herbicide. The United States Environmental Protection Agency (EPA) considers glyphosate to be relatively low in toxicity compared to organochlorine and organophosphate pesticides.
Verwenden
Glyphosate is the active ingredient in several commercial herbicides. It is a broad-spectrum systemic herbicide for various types of weeds, grasses (Poaceae), and woody plants.
