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 ...
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 ...
[27] [28] Glyphosate is sometimes called an organophosphate, but is in-fact a phosphonate. Its chemistry, mechanism of toxicity and end-use as a herbicide are different from the organophosphate insecticides. The development of organophosphate insecticides dates back to the 1930s and is generally credited to Gerhard Schrader. [29]
Weeds controlled with herbicide. Herbicides (US: / ˈɜːrbɪsaɪdz /, UK: / ˈhɜːr -/), also commonly known as weed killers, are substances used to control undesired plants, also known as weeds. [1] Selective herbicides control specific weed species while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes ...
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. [ 2 ] As of 2009, sales of Roundup herbicides still represented about 10 percent of Monsanto's revenue despite competition from Chinese producers of other ...
On 19 September 2012, the journal Food and Chemical Toxicology published a peer-reviewed paper entitled "Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize." [ 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]
Crop desiccation. Desiccated potato plants prior to harvest. Pre-harvest crop desiccation refers to the application of an agent to a crop just before harvest to kill the leaves and/or plants so that the crop dries out from environmental conditions, or "dry-down", more quickly and evenly. [1][2][3] In agriculture, the term desiccant is applied ...
