Which of the following sections under FIFRA exempts from registration pesticides considered to pose minimum risk?

The correct answer is based on Section 25(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), which provides an exemption for certain minimum-risk pesticides from the registration requirements. This section specifically defines and lists the criteria for what constitutes a minimum-risk pesticide, allowing products that meet these criteria to be marketed without the need for the extensive registration process typically required for conventional pesticides.

Farmers, pest control operators, and others in the agricultural and environmental sectors often use these minimum-risk pesticides because they tend to have lower toxicity and are considered safer for both humans and the environment. This regulatory framework aims to ease the burden of compliance for products that do not pose significant risks while still ensuring safety and efficacy in pesticide use.

Section 25(a), Section 25(c), and Section 25(d) do not provide similar exemptions or are focused on other aspects of pesticide regulation, making Section 25(b) the specific section pertinent to minimum-risk pesticide exemptions.
