Section 18 Registrations
To counter an unusual pest or set of circumstances, the Texas Department of Agriculture requests the Environmental Protection Agency grant Section 18 emergency specific exemptions or a more immediate crisis exemption.

This allows use of a new pesticide product or one not approved for a specific crop to stem a problem. TDA must provide EPA with data showing that the requested pesticide will do the job safely and effectively. The difference between a farmer making a crop or suffering a disaster often depends on the relief a Section 18 pesticide offers. The use of Section 18 pesticides annually save Texas farmers between $20 million and $30 million.

The Texas Pesticide Law and Regulations provides that the department address the special local need for a pesticide. TDA will determine that a local need exists; that the applicant meets all federal requirements for registration of a pesticide; that the particular use of the pesticide has not been denied, suspended, or canceled by the EPA; and that the products efficacy data support the claims made for it in Texas prior to approval of the application by the department.
