Roadside Spraying Program
Roadside spraying in SDG Counties takes place in May and June of each year. Spraying occurs from the edge of the gravel shoulder to within one metre of the property limits and uses selective, Government of Canada-approved herbicides to control the growth of undesirable vegetation. The contractor performing the work is fully licensed. Spraying occurs in areas identified during regular weed audits.
For the 2026 season, the United Counties of SDG intends to utilize Wagar and Corput Weed Control Inc. to control noxious weeds along guardrails and roadsides. Click on the attached notice and map for further information on the location of spraying.

No-Spray Signage
If you do not want the right-of-way in front of your property to be treated:
- You must post “NO SPRAY” signs (like the one above) at the start and finish of your property.
- The “NO SPRAY” signs must be at least one foot by two feet and located three feet from the edge of the gravel shoulder. Signs must be one foot above any vegetation so that it is easy to see from the road.
Spraying will not occur if the ditch is mowed on a regular basis (maintained as a lawn). To ensure that spraying does not occur, we recommend you install a sign regardless of how the ditch is maintained.
