|Thistle rust: a potential biocontrol agent for Canada thistle (General)
A team of researchers at Montana State University and the Montana Biocontrol Coordination Project are working on using a fungal rust as a potential biocontrol agent to help manage Canada thistle. The research is just beginning to assess how well the rust reduces Canada thistle patches. In the attached document there is a description of the rust, and it’s complicated life cycle. Stay tuned for more research results.
In the meantime, our team is interested in identifying locations to collect more thistle rust and documenting its occurrence and impact on Canada thistle. If you need a positive identification of the fungus contact your local county agent or submit a sample to the Schutter Diagnostic Lab ( https://diagnostics.montana.edu/), and reach out to us at http://ipm.montana.edu/cropweeds/ and https://www.mtbiocontrol.org/.

|Videos on diagnostic lab and plant path research (General)
The Extension Plant Pathology Lab at MSU has done a couple of videos on current research activities and the newest video covers cold wheat, tan spot, WSMV, and fungicide decision making in field crops. Check them out on the Extension YouTube channel. They are all very short. We are hoping this will be a good way to convey information with reduced travel and group sizes allowed.
