What is required for applying pesticides directly to water bodies in Wisconsin?

Applying pesticides directly to water bodies in Wisconsin requires obtaining a permit from the Department of Natural Resources (DNR). This requirement is in place to protect aquatic ecosystems and ensure that pesticide use does not adversely affect water quality or non-target organisms. The DNR evaluates permit applications to assess potential environmental impacts and to ensure that application methods adhere to state regulations aimed at safeguarding public health and natural resources. By requiring a permit, the state can maintain oversight over these activities and promote responsible pesticide use in sensitive environments.
