End-of-season assessment of sclerotinia stem rot of canola (PCDMN)
The spring and summer of 2023 was challenging for Prairie producers who experienced very dry conditions, especially under dryland production. Although this limited disease issues, the drought stress had a very significant negative impact on stand establishment, crop growth, and yield. However, some Prairie regions did receive moisture during the course of the summer and…

2023 Cereal Rust Risk Report (Mini and final update for June 18-July 21, 2023)
The main period for rust risk is largely over for most spring-seeded cereals. Typically, the greatest impacts occur when rust arrives prior to head emergence. Arrival of rust after head emergence and during the grain filling period will have a lower impact, although low to moderate yield losses can occur for susceptible varieties. Sources of…
