Regulations around water: can you apply pesticides to water of the state?

• A. You cannot apply pesticides to a water of the state.
• B. Water applications require no permit.
• C. A permit from DNR is optional.
• D. You must obtain a permit and meet related certification/licensing requirements to apply to water

Answer: (B)

Regulating pesticide use on water focuses on protecting water quality and aquatic life. In Wisconsin, applying pesticides to water of the state isn’t done on a whim—you must have the right authorization. Specifically, you typically need a permit from the Department of Natural Resources and you must hold the appropriate pesticide applicator certification or licensing for aquatic applications. This ensures you follow the product label, safety practices, and any environmental protections tied to water uses. The idea that no permit is needed or that a permit is optional isn’t correct because water applications are subject to regulatory oversight precisely to prevent contamination and harm to aquatic ecosystems. Always secure the permit and meet the related certification/licensing requirements before applying pesticides to water.
