Pesticide Registrations (June 26, 2013)

The Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), was first passed in 1947 and required that all pesticides sold in the U.S. be registered by the EPA. It was originally focused on protecting consumers from ineffective products and did not regulate pesticide use. It was rewritten in 1972 and now mandates that the EPA regulate product use to protect human health and the environment. The EPA also has the authority to approve the use of unregistered pesticides for use to address emergencies or special local needs. There are 3 basic types of registrations that are defined under sections of FIFRA:

Section 3 - Federal Registration - This registration is for product use on labeled sites throughout the United States. These products have gone through a complete EPA review and met all of the requirements for registration. States can, however, apply certain restrictions within their borders.

Section 24(c) - Special Local Need (SLN) - This registration allows states to register products that already have federal registrations for additional sites or uses to address special local needs. There are 2 types of SLN’s:

1. First party SLN where the applicant is the registrant of the product.

2. Third party SLN where the applicant is someone other than the registrant such as a grower, PCA, University etc.

Section 18 - Emergency Exemption - This registration allows states to approve the use of unregistered products for emergency pest conditions in a specific region for a limited time. Other options are normally not available. It is rare to obtain this type of registration for weeds that have been present for years.
