Weed Control

Westlock County sprays half the municipality's road allowances annually. Spraying begins as early as June 1st and can continue up to August 31st. There is public notification each year announcing the area to be sprayed. Spot spraying may be conducted in other locations as designated by the Agricultural Fieldman.

Weed Identification Service

Please bring in any suspect weeds for identification - early detection and early eradication are key components to achieve optimum control and prevent small infestations from growing into large problems.

Weed Inspection Program

Westlock County conducts annual weed inspections to control the growth and spread of noxious weeds within the County. Weed inspections begin as early as June with all lands in the County inspected each year. Landowners who have weed infestations are notified and informed of appropriate actions to resolve the issue. The standard time frame for weed control is 7 days.

No Spray Agreements

Any resident who does not want spraying alongside their property, must complete a No Spray Agreement with the County and post the supplied signs. Landowners are then responsible for weed control. This agreement is only in effect for the period of one year. Deadline to complete the agreement is the last business day in May annually. Please call the office at 780-349-3346 and select Agriculture for more information or to obtain an agreement.

Under the Alberta Agricultural Pests Act, Westlock County's agricultural staff enforce clubroot control measures. From early July to late October, our staff survey canola fields across the County for clubroot. Staff may enter private land at a reasonable hour, without permission, to inspect for clubroot and other pests under the Act. Fields known to have clubroot from previous years will also be monitored to ensure that the disease is being managed. A notice may be issued under the Act to prevent the spread and establishment of the disease depending on the clubroot severity and control measures being taken. Owners and occupants of the land are responsible to take steps to prevent and control clubroot on their land.
