The Minnesota Department of Agriculture (MDA) together with partners at the Minnesota Department of Health (MDH) and the Minnesota Pollution Control Agency (MPCA) have concluded the special registration review of the corn herbicide atrazine for the State of Minnesota.  This review determined that no modifications to atrazine regulation are required in Minnesota at this time.  Elements of atrazine registration and regulation may need revision if emerging science or EPA evaluations reach new conclusions about human health and environmental impacts of atrazine and its benefits to farmers.
