Which Endothall restriction applies to liquid formulations?

• A. Classified as restricted use for liquid formulations.
• B. Endothall is not restricted for liquid formulations.
• C. Endothall may be used freely in public water supply watershed.
• D. Endothall is banned entirely.

Answer: (A)

Endothall in liquid form is treated as a restricted-use pesticide. This designation means that only certified applicators may purchase and apply it, and they must follow all label directions and any extra precautions on the label. Liquid formulations can more readily move in water and affect non-target aquatic life, so the stricter status helps protect people, water resources, and ecosystems by ensuring properly trained handling, applying, and adherence to timing, dosage, and buffering requirements. The other statements—that there’s no restriction, free use in public water supply watersheds, or a complete ban—do not fit because the label explicitly requires certification and restricted-use handling for liquid Endothall.
