Such crops allow farmers to use glyphosate as a post-emergence herbicide against most broadleaf and cereal weeds. The genes contained in these seeds are patented. Monsanto also produced seeds which grow into plants genetically engineered to be tolerant to glyphosate, which are known as Roundup Ready crops. Another ingredient of Roundup is the surfactant POEA ( polyethoxylated tallow amine). The main active ingredient of Roundup is the isopropylamine salt of glyphosate. However, glyphosate is no longer under patent, so similar products use it as an active ingredient. The Roundup trademark is registered with the US Patent and Trademark Office and still extant. It retained exclusive rights to glyphosate in the US until its US patent expired in September 2000 in other countries the patent expired earlier. Monsanto developed and patented the glyphosate molecule in the 1970s, and marketed it as Roundup from 1973. The product is marketed to consumers by Scotts Miracle-Gro Company. The overall Roundup line of products, which includes genetically modified seeds, represented about half of Monsanto's yearly revenue. As of 2009, sales of Roundup herbicides still represented about 10 percent of Monsanto's revenue despite competition from Chinese producers of other glyphosate-based herbicides. Glyphosate is the most widely used herbicide in the United States. Roundup is the brand name of a systemic, broad-spectrum glyphosate-based herbicide originally produced by Monsanto, which Bayer acquired in 2018.

This article is about the herbicide developed by Monsanto.
