By volume, it is one of the most widely used herbicides. [56] In 2007, glyphosate was the most used herbicide in the United States agricultural sector, with 180 to 185 million pounds (82,000 to 84,000 tonnes) applied, the second-most used in home and garden with 5 to 8 million pounds (2,300 to 3,600 tonnes) and 13 to 15 million pounds (5,900 to ...
The glyphosate-based herbicide RoundUp (styled: Round up) was developed in the 1970s by Monsanto. Glyphosate was first registered for use in the U.S. in 1974. [4] Glyphosate-based herbicides were initially used in a similar way to paraquat and diquat, as non-selective herbicides. Attempts were made to apply them to row crops, but problems with ...
Roundup is a brand name of herbicide originally produced by Monsanto, which Bayer acquired in 2018. Prior to the late-2010s formulations, it used broad-spectrum glyphosate-based herbicides.

[ 29 ] [ 6 ] The two-year toxicity study, which cost €3.2 million, was conducted at the University of Caen by Séralini and seven colleagues.
Paraquat (trivial name; / ˈpærəkwɒt /), or N,N′-dimethyl-4,4′-bipyridinium dichloride (systematic name), also known as methyl viologen, is an organic compound with the chemical formula [ (C 6 H 7 N) 2]Cl 2. It is classified as a viologen, a family of redox -active heterocycles of similar structure. [5]
