Atrazine is a herbicide of the triazine class. Atrazine is a herbicide that is used to stop pre- and post-emergence broadleaf and grassy weeds in crops such as sorghum, maize, sugarcane, lupins, pine, and eucalypt plantations, and triazine-tolerant canola.
The triazine family of herbicides, which includes atrazine, were introduced in the 1950s; they have the current distinction of being the herbicide family of greatest concern regarding groundwater contamination.

Cyanuric chloride

cyanuric trichloride
Atrazine is prepared from cyanuric chloride, which is treated sequentially with ethylamine and isopropyl amine.
Cyanuric chloride is the main precursor to the popular but controversial herbicide atrazine.

Syngenta

Agricultural Research StationNovartisNovartis Seed Co.
It was banned in the European Union in October 2003, when the EU found groundwater levels exceeding the limits set by regulators, and Syngenta could neither show that this could be prevented nor that these levels were safe.
Atrazine is an herbicide of the triazine class.

Isopropylamine

isopropyl amine
Atrazine is prepared from cyanuric chloride, which is treated sequentially with ethylamine and isopropyl amine.
Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione.

Endocrine disruptor

endocrine disruptionendocrine disruptorsendocrine disrupting chemicals
Studies suggest it is an endocrine disruptor, an agent that can alter the natural hormonal system.
Some other examples of putative EDCs are polychlorinated dibenzo-dioxins (PCDDs) and -furans (PCDFs), polycyclic aromatic hydrocarbons (PAHs), phenol derivatives and a number of pesticides (most prominent being organochlorine insecticides like endosulfan, kepone (chlordecone) and DDT and its derivatives, the herbicide atrazine, and the fungicide vinclozolin), the contraceptive 17-alpha ethinylestradiol, as well as naturally occurring phytoestrogens such as genistein and mycoestrogens such as zearalenone.

Ethylamine

ethanamineMEAmonoethylamine
Atrazine is prepared from cyanuric chloride, which is treated sequentially with ethylamine and isopropyl amine.
Ethylamine is a precursor to many herbicides including atrazine and simazine.

Alachlor

Lasso
Like the herbicides trifluralin and alachlor, atrazine is susceptible to rapid transformation in the presence of reduced iron-bearing soil clays, such as ferruginous smectites.
It is marketed in mixed formulations with atrazine, glyphosate, trifluralin and imazaquin.

Novartis

Atrazine was invented in 1958 in the Geigy laboratories as the second of a series of 1,3,5-triazines.

In the United States as of 2014, atrazine was the second-most widely used herbicide after glyphosate, with 76 million pounds of it applied each year.

Tyrone Hayes

A 2002 study by Tyrone Hayes, of the University of California, Berkeley, found that exposure caused male tadpoles to turn into hermaphrodites – frogs with both male and female sexual characteristics.
Tyrone B. Hayes (born July 29, 1967) is an American biologist and professor of Integrative Biology at University of California, Berkeley known for his research findings concluding that the herbicide atrazine is an endocrine disruptor that demasculinizes and feminizes male frogs.

Simazine

Like atrazine, a related triazine herbicide, it acts by inhibiting photosynthesis.

Food Quality Protection Act

FQPA
In 2006 the U.S. Environmental Protection Agency (EPA) had stated that under the Food Quality Protection Act "the risks associated with the pesticide residues pose a reasonable certainty of no harm", and in 2007, the EPA said that atrazine does not adversely affect amphibian sexual development and that no additional testing was warranted.
