For example, the seed size of a CWRS variety can be as low as 30 g/1,000 seeds under drought conditions, but with excellent moisture seed size for this same variety can be 40-45 g/1,000 seeds. Therefore, to achieve desired plant populations, seeding volumes must be calculatedThree Hills, AB based on the seed size of the seed lot that you will be planting.

Fusarium graminearum (Fg) is no longer a designated pest in Alberta. Removal of Fusarium graminearum from the Pest and Nuisance Control regulation brings Alberta in-line with best practices from other provinces and allows farmers access to the most current seed varieties (which may have improved Fg resistance) and cereal research. As such, we are using best management practices in the Alberta RVTs to responsibly address this disease. Spring 2023 65'
