Provincially regulated plant pests and diseases

Albertans must take active measures to prevent the establishment and spread of these declared crop pests in Alberta.


The Agricultural Pests Act is the key legislation providing authority for the Minister to declare as a pest or nuisance any animal, bird, insect, plant or agricultural disease. Declared pests and nuisances are either known or likely to destroy or harm any land, livestock or property in Alberta. Because of this, declared pests and nuisances require either investigation, if suspected to occur at a location, or active monitoring and control. Owners and occupants of land or property must use sound management practices that comply with applicable laws to prevent establishment, control or destroy regulated pests on their land or property. The legislation also enables local authorities to appoint inspectors to deal with regulated pests and nuisances that affect agricultural production or infrastructure.

In this section, you’ll find information on a selection of declared plant pests. See the full list of plant pests below:

For all declared pests and nuisances – including animals, birds, insects, plants and agricultural diseases, see Alberta’s Pest and Nuisance Control Regulation.
