Minor Uses and Grower Resources
This web page provides growers, pesticide manufacturers (registrants) and other interested parties with information about EPA programs designed to ensure safe pesticide tools are available, particularly for those interested in pesticides for the minor uses. A major part of this effort involves the partnerships with other organizations and stakeholders.

Minor use crops have fewer than 300,000 acres in production in the United States. The small acreage may provide insufficient economic incentive for pesticide companies (i.e., registrants) to keep their products registered for use on these crops, or to register new minor use pesticides. Many fruits and vegetables qualify as minor crops. Minor uses also include pesticides applied for control of disease vectors such as mosquitoes, ticks, cockroaches, rodents and disease-causing organisms.
Codex MRL Nominations
The Codex Committee on Pesticide Residues (CCPR) is responsible for establishing maximum residue limits (MRLs) for pesticide residues in specific food items or in groups of food for Codex.
U.S. Grower Priorities for International MRLs
U.S. Grower MRL Priority Database
The U.S. Grower MRL Priority Database Exit is a useful tool for U.S. grower groups seeking to identify and communicate their MRL needs in major export markets to registrants and governments. All U.S. grower groups are encouraged to enter their priorities.
USDA International Maximum Residue Level Database
The USDA International Maximum Residue Level Database Exit is a tool for growers who want to export a commodity to determine if there is a foreign market MRL when an EPA tolerance is in place for the same commodity.
In an effort to prevent trade irritants, the EPA and Canada’s Pesticide Management Regulatory Agency (PMRA) participate in joint reviews of minor uses. The two countries review submissions and make regulatory decisions at approximately the same time.

Crop groups are an important tool for growers and especially for growers that need pesticide options for minor crops. Codified crop groups are located in the Code of Federal Regulations 40 § 180.41. The EPA is involved in efforts to revise the crop grouping regulations.

FIFRA exclusive use provisions for minor use registrations provide incentives to pesticide companies to register minor uses of pesticides. Registrants submit studies to EPA when registering a pesticide. FIFRA authorizes a period of time for “exclusive use” of the studies by the company after they register a new pesticide or add a new use for an existing pesticide. In the exclusive use period, only the registrant who developed the data may use it to support additional registrations. This is similar to a patent, allowing exclusive use of the supporting data for a specific period of time. In some circumstances, registration of a minor use may either extend the exclusive use period or establish a new exclusive use period.
- Questions and Answers - Exclusive Use Data Protection for Minor Use Registrations - Information about FIFRA exclusive use provisions for minor use registrations, including information for registrants on how to apply for an extension of exclusive use rights.
Extending the Exclusive Use Period for an Active Ingredient - FIFRA § 3(c)(1)(F)(ii)
FIFRA § 3(c)(1)(F)(ii) lists the criteria to be met for extending the exclusive use period, for 1 additional year for each 3 minor uses registered after the date of enactment, up to 3 additional years, based on information provided by an applicant for registration or a registrant.
- View the petitions filed by registrants for extensions of exclusive use periods for an active ingredient under FIFRA, § 3(c)(1)(F)(ii) and, where applicable, EPA's response. Note that in some cases responses from the Agency are pending.
Establishing a New Exclusive Use Period for a Specific Commodity- FIFRA § 3(c)(1)(F)(vi)
FIFRA § 3(c)(1)(F)(vi) lists the criteria to be met to establish a new exclusive use period for data submitted to add a minor use to an existing registration after the period of exclusive use protected data has expired. A registrant must request this new exclusive use period at the time of application, unlike the extension request described above.

The term “minor use” means the use of a pesticide on an animal, on a commercial agricultural crop or site, or for the protection of public health where:
- the total United States acreage for the crop is less than 300,000 acres, as determined by the Secretary of Agriculture; or
- EPA, in consultation with USDA, determines that, based on information provided by an applicant for registration or a registrant, the use does not provide sufficient economic incentive to support the initial registration or continuing registration of a pesticide for such use and —
- there are insufficient efficacious alternative registered pesticides available for the use;
- the alternatives to the pesticide use pose greater risks to the environment or human health;
- the minor use pesticide plays or will play a significant part in managing pest resistance; or
- the minor use pesticide plays or will play a significant part in an integrated pest management program.
The status as a minor use under this subsection continues as long as EPA has not determined that, based on existing data, such use may cause an unreasonable adverse effect on the environment and the use otherwise qualifies for such status.
