Under Section 18 of FIFRA, MDA can apply for an emergency exemption from federal registration in order to allow the use of an unregistered pesticide in an emergency situation. An emergency situation must be urgent and non-routine and could include: an outbreak of a new pest, development of resistance to existing pesticides, unusual weather conditions that caused a pest outbreak, or product cancellation.

Section 18

Section 18 registrations provide exemptions from pesticide registration under emergency conditions. An emergency is considered an urgent, non-routine situation. Refer to our Section 18 Guidelines for details.
