Wild Parsnip Control in Little River Corridor and Ojibway Prairie Complex

The City of Windsor has hired a contractor for the application of herbicide to control wild parsnip, an Ontario Noxious Weed. This is in accordance with the Public Health and Safety exception to the cosmetic pesticide ban that affects the Parks Department. 

Weather permitting, the work will begin on June 22, 2026, and will end by July 31, 2026. Application will occur along the Ganatchio Trail System in the Little River Corridor, Spring Garden Natural Area and Titcombe Trail in the Ojibway Prairie Complex using the following pesticide registered under the Pest Control Products Act (Canada): Navius Flex pest control product (PCP) #30922, containing the active ingredient aminocyclopyrachlor. This is the second round of control this year that is specifically targeting the second-year plants before they produce seed. 

Wild parsnip stems, leaves, and flowers contain chemicals that can cause painful blisters, burns, and dermatitis when skin makes contact with the plant sap followed by sun exposure. Wild parsnip is also an invasive species that can reduce local biodiversity and the quality of habitat available for native plants and wildlife.
