ASB Roadside Invasive Weed Control

Invasive weed control remains an Agricultural Service Board priority. The 2023 annual roadside spraying program will take place in the southern third of the county from Township Road 30-4 to the southern border. Spot spraying will be done in other areas as needed. The gravel recovery spraying will involve a targeted approach and focus on specific roads throughout the County. 

Two Agriculture Services spray units will be applying a residual herbicide and have been instructed to leave a one-meter buffer strip between the road allowance and the adjacent landowners’ property. As per policy, all roadside spraying will stop 30 meters upon approaching a farmstead or residence, where buildings and trees are within 30 meters of the road allowance, and will continue 30 meters past the farmstead or residence. These buffer areas are the responsibility of the adjacent landowner.

Urban and Rural Weed Inspection

In accordance with the Alberta Weed Act, Kneehill County has appointed inspectors to assist the public in identifying and controlling regulated species. Twice during the growing season, inspectors will visit all urban municipalities within Kneehill County to scout for invasive species, let homeowners know about the plants and aid in determining the best control methods. 

Inspectors will also be completing similar scouting throughout the rural areas of the County.
