Clubroot was added as a declared pest to the Agricultural Pests Act in April 2007. The owner or occupant of land has the responsibility of taking measures to prevent the establishment of any pest on land, property, and livestock, and to control or destroy all pests on the land or property. Enforcement of pest control measures is the responsibility of the municipal authority Kneehill County ASB. By virtue of the office, the Agricultural Fieldman is a pest inspector under the Agricultural Pests Act. Pest inspectors have the power to enter land at any reasonable hour, without permission, to inspect for pests and collect samples.
