Wild Parsnip


Please be advised that Tay Valley Township will not be conducting a roadside spraying program to control the spread of Wild Parsnip in 2020 along Township roads and properties. 

Tay Valley will continue our roadside mowing program, as in past years, along Township roads. Tay Valley will be monitoring the Wild Parsnip situation in 2020 and making note of areas of infestation so that we can make informed decisions on this issue in future years.

If you live, or own property, adjacent to a Township Road within Tay Valley the road allowance will be mowed as it has been in past years.

Wild Parsnip is an invasive plant that is increasingly common within Lanark County and was added to Ontario’s list of Noxious Weeds in January, 2015. The plant is most commonly found in areas such as road shoulders, roadside ditches, rail corridors, trails and uncultivated lands.

Wild Parsnip may pose a health risk to humans as the plant sap may cause skin and eye irritation and make the skin prone to sever burning and blistering when exposed to the sun. The blisters typically occur one to two days after contact with the plant. In some cases, this can result in long term scarring of the skin.

The best way to avoid contact with Wild Parsnip is to become familiar with what the plant looks like and the proper handling techniques when dealing with the plant.
