Which section under FIFRA exempts from registration pesticides considered to pose minimal risk?

The section under FIFRA that exempts from registration pesticides considered to pose minimal risk is Section 25(b). This section establishes a process for the EPA to categorize certain pesticide products as "minimum risk" based on specific criteria. Products that meet these criteria can be marketed without the need for full registration, allowing for a streamlined approach for those whose active and inert ingredients are considered to be safe and pose minimal risk to human health and the environment. Thus, Section 25(b) serves as an important regulatory framework for promoting the use of safer pest control options while maintaining oversight.

The other sections, such as Section 18, refer to emergency exemptions for using unregistered pesticides in specific, urgent situations, Section 3 covers the general process for registering pesticides, and Section 24(c) pertains to state registrations of pesticides for special local needs, all of which do not pertain to the exemption of minimal risk pesticides under FIFRA.
