Atrazine is in a perennial battle between the agricultural chemical industry and environmental groups. Caught in the middle are state and federal regulators and the farmers who actually apply atrazine on corn, sorghum, and other crops. The latest spat is over a 2009 reevaluation of triazine herbicides (to which atrazine belongs) by the Obama administration. This follows a regularly scheduled triazine federal reregistration that the EPA approved under the Bush administration.

What does this mean to you? It’s possible that atrazine could be banned under this reevaluation. That’s what happened in the European Union in 2003, when regulators banned atrazine due to concerns about its impact on health and the environment. It’s also possible that more restrictions could result, such as lower rates Or, you could continue using this popular corn herbicide as you always have.


Atrazine is a widely used herbicide that can be applied before and after planting to control broadleaf and grassy weeds. Atrazine is a member of the triazine chemical class, which includes simazine and propazine. It is used in primarily in agriculture, with the greatest use on corn, sorghum, and sugarcane. To a lesser extent, it is used on residential lawns and golf courses, particularly in the Southeast United States. 

The Agency’s oversight of atrazine is dynamic and includes periodic re-evaluation through the registration review process. Over the years, the Agency has consulted with the FIFRA Scientific Advisory Panel (SAP) on a variety of atrazine topics.

Features of Atrazine Herbicide

  • Kills many broadleaf weeds
  • Also used in centipede grass
  • Provides suppression of crabgrass
  • Controls emerged weeds and weeds from seed

Long Term Exposure

Atrazine interrupts regular hormone function, causing birth defects, reproductive tumors, and weight loss in mothers and embryos. Atrazine may cause skin sensitization and allergy. Atrazine has the potential to cause weight loss, cardiovascular damage, retinal and some muscle degeneration, and mammary tumors from a lifetime exposure at levels above the MCL. There is the increased risks for tumors known to be associated with hormonal factors. These have been observed in both animals and human beings, and are consistent with the known effects of atrazine on the hypothalamic pituitary gonadal axis. May be a neurotoxin.
