A state may add uses to a federally registered pesticide through which registration?

• A. 24(c) registration
• B. 24(d) registration
• C. 24(a) registration
• D. Emergency exemption

Answer: (A)

Special Local Needs registrations let a state add uses to a federally registered pesticide. This mechanism, under FIFRA, allows a state to request EPA approval to modify the product’s use pattern for that state and to adopt state-specific labeling that governs those added uses. The federal label remains in place nationwide, but the SLN label applies within the state, ensuring the added uses are overseen and aligned with safety data.

This is the mechanism that directly answers how a state can expand the uses beyond the federal labeling to meet local pest management needs. Emergency exemptions are temporary responses to urgent problems and not the routine way to broaden a product’s labeled uses, and the other options pertain to different aspects of labeling or registration.
