Glyphosate is the active ingredient of many widely used, broad-spectrum herbicides and is commonly applied as a broadleaf weedicide in commercial agriculture. Created by Monsanto in 1970 and marketed from 1974 as “Roundup”, glyphosate has been used extensively across the world ever since1. Although the USA remains its biggest consumer, the use of glyphosate has also increased in other countries. As such, from 1999 to 2010 glyphosate use in Germany increased by 100%, now being sprayed on nearly 40% of German farmland each year2. Due to such extensive use, the genetically modiﬁed crop plants called “Roundup Ready” were created, which are resistant to glyphosate. This further increases the use of this herbicide. The majority of soybean, cotton and corn crops grown in the USA today are of this Roundup Ready variety, which is heavily exposed to glyphosate3.
