Glyphosate

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. It was discovered to be a herbicide by Monsanto chemist John E. Franz in 1970.[3] Monsanto brought it to market in the 1970s under the trade name “Roundup”, and Monsanto’s last commercially relevant United States patent expired in 2000.
