Pesticide Registration Requirements

WSDA has the authority under Section 24(c) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to register an additional use of a federally registered pesticide on a food or feed crop for which a tolerance has been established (or on a non-food or non-feed crop or site) for use in a special local need pest situation.
 
The U.S. Environmental Protection Agency (EPA) defines “special local need” as an existing or imminent pest problem within a State for which the State lead agency, based upon satisfactory supporting information, has determined that an appropriate federally registered pesticide product is not sufficiently available. A special local need (SLN) registration could include a new application method or timing, different rate, new crop, new pest, less hazardous formulation, prevention of pesticide resistance, or application to a different soil type. Note that requests based on prevention of pesticide resistance have additional criteria to address. For additional EPA guidance visit EPA’s Guidance on FIFRA 24(c) Registrations.
 
The applicant for an SLN registration is usually the registrant for the pesticide product.
