2016 Roadside Spraying

Vegetation control along the County roadsides is an important part of road maintenance. It ensures clear sight lines for signs, intersections and roadside wildlife, promotes drainage and drying and prevents the establishment of trees and brush in the right of way. Controlling noxious and invasive weeds is another objective of the County vegetation management program.

Roadside herbicide spraying will be completed in May and June along rural County roads within the municipalities of Augusta,
Edwardsburgh/Cardinal, Elizabethtown-Kitley, Merrickville-Wolford and North Grenville as well as selected township roads in the municipalities of Augusta, Edwardsburgh/Cardinal, Elizabethtown-Kitley, Front of Yonge, Leeds and Thousand Islands, Merrickville-Wolford, North Grenville and Rideau Lakes (see 2016 Spray Maps). The herbicide will selectively kill weeds but not the grasses and is approved for use on roadsides under the public works exemption of the cosmetic pesticide ban. Spraying of the herbicide will be completed by a qualified contractor licensed by the Ministry of the Environment under requirements of the Pesticides Act. Only unmaintained ditches will be sprayed with herbicide, maintained yards and ditches will not be sprayed. A public notice of this pesticide use will be advertised in the local papers and on the township and Counties websites.

Property owners who do not want the unmaintained ditch in front of their property sprayed can post "No Spray" signs at the start and finish of their property. These signs must be at least 30 cm x 60 cm (1 ft x 2 ft) and be easily read from the shoulder of the road. You can make your own sign or the Counties have a limited number of these signs available for pick up at the Counties office in Brockville. To obtain one of these signs or for more information please contact the Counties at 613-342-3840 ext. 2413.
