Entity of the month
Glyphosate (CHEBI:27744, trade name: Roundup), is an organophosphorus compound discovered by a team of scientists led by Dr John Franz and brought to market for agricultural use in 1974 by Monsanto. It is the most widely used systemic broad-spectrum herbicide and crop desiccant in the US; in 2014, total worldwide consumption of glyphosate stood at 826 million kg [1]. After its patent expired in 2000, the chemical began to be sold by several manufacturers and is a constituent in more than 750 products being sold in the US [2]. Despite this competition, Monsanto is still a dominant player in the market and focusses its strategy on genetically modified (GM) glyphosate resistant crops.
