Promoting Research & Education In Plant Pathology
The Canadian Phytopathological Society (CPS) is a scientific society formed in 1929 as a nonprofit organization enabling plant pathologists to meet and discuss their common interests in teaching and researching plant diseases.

Upcoming CPS Workshop
We invite you to attend our hands-on workshop, titled “Identification of Rust Fungal Species Using Metabarcoding and AODP”, held as part of the Joint Meeting of the 17th International Cereal Rusts and Powdery Mildews Conference and the 2025 Annual Meeting of the Canadian Phytopathological Society, taking place between June 15-21, Vancouver, BC, .
This interactive session focuses on cutting-edge applications of diagnostic metagenomics in modern agriculture and plant pathology. Participants will learn how to use short-read metabarcoding data and our in-house bioinformatics tool, AODP (Automated Oligo Design Pipeline), to achieve species- and subspecies-level pathogen identification — a crucial step toward improved disease surveillance and early warning systems.
With growing global threats from emerging plant pathogens, integrating bioinformatics into disease diagnostics has never been more important. Whether you’re a plant pathologist, microbial ecologist, or bioinformatics researcher, this workshop will equip you with practical tools to support high-resolution pathogen detection and decision-making in crop protection.
