From the Ward 3 Office with information from the City of Ottawa

We / our refers to the City of Ottawa

Second round of treatment

When pesticides are used:

To minimize disturbance to our parks and as per the Ontario Pesticide Act, only locations deemed to have a moderate to high level of infestation and a high risk to the public will be spot sprayed with Glyphosate. In other areas, lower levels of wild parsnip infestation will be mowed or pulled by hand.

Roads	Parks and Public Spaces
Continue and expand the application of Clearview and Navius FLEX herbicides to highly infested roadside areas; and, Continue mowing operations, adjusting frequency and timing to best coincide with herbicide applications roadsides.	Continue mowing operations as a primary mitigation strategy; Continue hand pulling smaller infestation; Per provincial legislation, continue application of Clearview and Glyphosate herbicide only when necessary; and, Post signage indicating locations where spraying occurs including larger infestations in naturalized areas.

How is it completed:

Where spraying occurs, residents should expect to see wilting or discolouration in two to four days. The full impact of the spray could take up to 20 days. The contractor will sign locations before spraying and remove the signage once the spraying is complete.
