Glyphosate (IUPAC name: N-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide and crop desiccant.It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSP).
The glyphosate-based herbicide RoundUp (styled: Roundup) 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 ...
A review of glyphosate's carcinogenic potential by four independent expert panels, with a comparison to the IARC assessment, was published in September 2016. Using emails released in August 2017 by plaintiffs' lawyers who are suing Monsanto, Bloomberg Business Week reported that "Monsanto scientists were heavily involved in organizing ...
On September 21, 2009, U.S. District Judge Jeffrey S. White, U.S. District Court for the Northern District of California, ruled that USDA-APHIS had violated Federal law in deregulating glyphosate-resistant sugar beet [159] and on August 13, 2010, he ruled further, revoking the deregulation of glyphosate-resistant sugar beet and declaring it ...
Glyphosine is a plant growth regulator used on sugar beet and sugarcane.It inhibits fiber production, causing the plant to divert more dry matter to sucrose storage. [1] 76,000 pounds (34,000 kg) of glyphosine were used in the US in 1974. [3]
As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. [ 7 ] [ 8 ] While the use of Roundup Ready crops has increased the usage of herbicides measured in pounds applied per acre, [ 9 ] it has also changed the herbicide use profile away from atrazine , metribuzin , and alachlor [ citation needed ] which are more ...
The US EPA limits N-nitrosoglyphosate impurity to a maximum of 1 ppm in glyphosate formulated products. [1] N -Nitrosoglyphosate can also form from the reaction of nitrates and glyphosate. Formation of N -nitrosoglyphosate has been observed in soils treated with sodium nitrite and glyphosate at elevated levels, though formation in soil is not ...
Besides consuming phosphorus, M. aeruginosa thrives on glyphosate, although high concentrations may inhibit it. [24] M. aeruginosa has shown glyphosate resistance as result of preselective mutations, and glyphosate presence serves as an advantage to this and other microbes that are able to tolerate its effects, while killing those less tolerant ...
