Glyphosate, or N-(phosphonomethyl)glycine, was originally developed as a corrosion inhibitor, but it has been the world’s most widely used herbicide for almost 40 years. Monsanto patented it in the early 1970s and began to sell it under the trade name Roundup. More recently, the company developed glyphosate-resistant transgenic crop seeds.
