Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizes the U.S. Environmental Protection Agency (EPA) to allow Emergency Exemptions (also called “Section 18s”) for unregistered uses of pesticides to address emergency pest conditions. Under such an exemption, EPA allows use of a pesticide in Minnesota for a limited period of time once EPA confirms that the situation meets the statutory definition of "emergency condition."

List of emergency exemptions


Definition of “Emergency Condition”

Federal regulations define an emergency condition as an urgent, non-routine situation that requires the use of a pesticide(s). Any emergency condition exists only when the situation is urgent and non-routine and all three conditions are met:

  1. No effective registered pesticides are available.
  2. No feasible alternative control practices are available.
  3. The situation a) involves the introduction or spread of a new pest, b) will present significant risks to human health or the environment, or c) will cause significant economic loss.


What is the process in Minnesota for requesting Section 18?

Emergency exemptions are typically requested by crop growers, crop advisors, or others faced with an emergency situation:

  • Growers identify a problem situation which registered pesticides will not alleviate.
  • The growers contact their technical expert at the University of Minnesota.
  • The technical expert contacts the registrant of the requested pesticide to determine if the registrant supports a Section 18.
  • The MDA encourages the technical expert to contact MDA at this point, prior to submitting an application.
  • The technical expert prepares and submits an application package to the MDA.  The expert uses the federal application requirements found at Title 40 of the Code of Federal Regulations, part 166 to create an outline format for the application package.
  • The MDA conducts a review of the application package for completeness and makes a preliminary determination of whether the application successfully demonstrates that an emergency condition exists and provides feedback to the expert as needed. 
  • If the MDA determines the request is warranted, the MDA may then submit the application package to the EPA.
  • The EPA reviews the package. Typically, the EPA attempts to make decisions on the requests within 50 days of receipt.
  • If EPA issues an exemption, the exemption and Minnesota-specific Section 18 label are in effect for a limited time (no longer than one year), to address the emergency situation.
