All MDA services should now be working after Friday's worldwide vendor technology outage. We apologize for any inconvenience this may have caused.

The MDA performs special registration reviews on new pesticide active ingredients and currently registered pesticides that have significant new uses approved by the U.S. Environmental Protection Agency (EPA). In the process of completing a review, the MDA extensively analyzes the EPA risk assessments for a variety of human health and ecological risk issues relevant to Minnesota. The MDA also assesses laboratory analytical concerns for tracking potential misuse and non-target impacts, and reviews the product labels for any difficult to interpret or uncommon label language. Information on projected crop use and efficacy is gathered from University of Minnesota Extension, user groups and others. Reviews may also include communication with EPA or the registrant to request more information about identified concerns.

Special registration reviews are included in the table below. The type of review (new active ingredient or new use) and information on any subsequent registered uses is included. The PDF document for each pesticide includes information on how the pesticide works, where it's used, its environmental fate, and its toxicity to humans and other species.
