Western Committee on Plant Diseases: Terms of Reference

The Western Committee on Plant Diseases (WCPD), previously known as Western Committee on Plant Disease Control (WCPDC), was organized as one of the four committees under the auspices of Western Forum, in 1976. It functions as an advisory body to provincial government advisory committees of the four western provinces and to other agencies and stakeholders concerned with plant disease control and surveillance within the region.

The WCPD previously published the Guidelines for the Control of Plant Diseases in Western Canada. The guidelines were reviewed and updated annually as part of the Western Forum on Pest Management. As of 2016 the guidelines are no longer being updated.
