CROP HEALTH: EPA Proposes Additional Mitigations for Atrazine

The Environmental Protection Agency (EPA) has released for public comment “Proposed Revisions to the Atrazine Interim Registration Review Decision.”


Atrazine is an important tool for weed mitigation in several crops, including corn, sorghum and sugarcane.  The use of atrazine, especially in corn and sorghum production, provides added environmental benefits for farmers seeking to utilize conservation tillage and no-till practices that conserve soil, preserve and increase nutrients, improve water quality, and reduce greenhouse gas emissions.

Without atrazine, many farmers would not be able to utilize these methods, which result in positive environmental outcomes.


Specifically, the EPA is proposing a concentration equivalent level of concern (CE-LOC) for atrazine of 3.4 micrograms per liter (µg/L).

EPA is also recommending a mitigation “pick list” - a combination of application rate reductions and/or runoff control measures when using atrazine in watersheds with atrazine concentrations that exceed the CE-LOC of 3.4 μg/L.


Tell EPA to use sound science and maintain farmers’ access to atrazine. Proposed mitigations would severely limit how farmers can use this product.
