Monsanto Company is a publicly traded American multinational agrochemical and agricultural biotechnology corporation headquartered in Creve Coeur, Greater St. Louis, Missouri. It is a leading producer of genetically engineered (GE) seed and Roundup, a glyphosate-based  herbicide. Monsanto's role in agricultural changes, biotechnology products, lobbying of government agencies, and history as a chemical company have made the company controversial.
