What does the minor use definition under FIFRA mainly consider?

The minor use definition under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) primarily focuses on public health use that is determined by both the acreage affected and the economic incentive associated with controlling specific pests. This aspect is crucial because minor uses are typically those that may not have a large agricultural market or significant economic return, but still, require effective pest control measures to safeguard public health.

Regulations recognize that certain pests may pose health risks, even in less common or smaller agricultural contexts, and work to ensure that there are options available for safely managing those pests. The relationship between the scale of use and economic viability plays a vital role in defining what constitutes a minor use, as it directs attention toward the management of pests that might otherwise be neglected in favor of more lucrative markets.

Considerations such as the type of pest, the geographic area, and the duration of control programs are secondary to the evaluation of the economic rationale behind pest control needs in the context of public health, which is why the other definitions do not encapsulate the essence of minor use as effectively.
