Looking to manage those pesky plants growing in your backyard pond?

In order to protect Wisconsin’s native aquatic plants and prevent the spread of invasive plant species, the WIDNR requires lake and pond owners to submit Aquatic Plant Management permitting for management approval. There are a few options for removal; Manual, Mechanical & Chemical. Many aquatic plants and certain algae species can only be managed with pesticides. If you choose chemical control, make sure to have the correct permitting in place before applying a treatment.

What kind of permitting do I need to chemically treat my pond weeds?

For chemical control, an NR107 permit is required. To find out more about permitting requirements and types please visit the Wisconsin DNR website.
