What does atrazine mean?
Atrazine is a synthetic herbicide belonging to the triazine family of chemicals, developed in the 1950s and used primarily to control broadleaf and grassy weeds in crops such as maize, sorghum, and sugarcane. It works by inhibiting photosynthesis in target plants, making it especially effective as a pre-emergent treatment before crops are established. The word appears most often in agricultural, scientific, environmental, and regulatory writing, where it carries connotations of both agricultural productivity and ecological concern: atrazine is among the most frequently detected pesticides in surface and groundwater worldwide, and the European Union banned its use in 2004 over water contamination concerns. In the United States it remains one of the most widely applied herbicides, which keeps the term prominent in debates over drinking-water safety and endocrine effects on wildlife. For general readers, atrazine exemplifies how a single chemical name can anchor discussions spanning farming practice, chemistry, and public health.
nounA synthetic herbicide of the triazine class, widely used to kill broadleaf and grassy weeds, especially in corn and sugarcane cultivation. It is also known as one of the most commonly detected agricultural pesticides in groundwater.
- A triazine-class herbicide (2-chloro-4-ethylamino-6-isopropylamino-s-triazine) used to control weeds in crops such as maize, sorghum, and sugarcane.
"Farmers applied atrazine in early spring to suppress weed growth before the maize seedlings emerged."
"The water utility reported elevated levels of atrazine following the spring planting season."
"Because atrazine persists in soil, crop rotation practices must account for its residual activity."
Rarely used; atrazine normally functions as an uncountable mass noun referring to the specific chemical substance. A plural would occur only when discussing multiple distinct formulations or derivatives, which is uncommon outside specialized chemistry literature.
"The study compared several atrazines produced by different manufacturers."
Banned across the European Union since 2004, atrazine is still one of the most heavily used herbicides in the United States.

Etymology of atrazine
Atrazine was coined in the mid-twentieth century by chemists who created it from 'at' (derived from part of its chemical name) combined with '-azine', a suffix used for six-membered heterocyclic ring compounds containing nitrogen, itself borrowed from German '-azin'. It belongs to a family of chemical terms built on this suffix, including triazine and hydrazine, all ultimately drawing on the '-ine' ending common in chemical nomenclature. The compound was first synthesized in Switzerland in the 1950s and quickly became a mainstay of modern weed control.
How atrazine is actually used
A technical term used mainly in agriculture, environmental science, toxicology, and regulatory contexts; it rarely appears in everyday conversation except in discussions of pesticide safety and water quality.
Easily confused with atrazine
Atropine is a drug derived from deadly nightshade used to dilate pupils and treat certain heart conditions, whereas atrazine is an agricultural herbicide.
