The Environmental Protection Agency (EPA) proposed cracking down on a widely used agricultural herbicide, sparking outrage from farmers who say the move could raise food prices and imperil farms around the country.

The EPA announced Thursday it was reopening the finalized reregistration for the chemical atrazine, claiming the Trump administration's "previous decision was not adequately supported by science," according to an agency memorandum.

"Based on this reevaluation, EPA determined that this level of regulation was not appropriate and is proposing, for public comment, additional mitigation to protect aquatic plant communities," the memo stated.
