Assembly Bill 289 seeks to prohibit the Wisconsin Department of Natural Resources (DNR) from using neonicotinoid insecticides on land that it maintains, with specific exceptions. The bill establishes a new statute, 29.601 (4m), which states that the DNR cannot apply these insecticides on its lands, except when such use is part of existing cooperative farming agreements or contracts, or for the purpose of controlling forest insects in designated areas, such as state forest nurseries and seed orchards.

The bill aims to protect the environment and promote sustainable practices by limiting the use of harmful insecticides. The exceptions outlined in the bill ensure that necessary agricultural and forestry practices can continue while still addressing concerns related to the impact of neonicotinoids on ecosystems.
