Crown rust in oats
MITIGATING CROP LOSS
-
UNDER THE RIGHT (or wrong) conditions, crown rust can be a real problem for oat growers. While most varieties carry some resistance, Albert Tenuta, plant pathologist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) warns that races do change over time, affecting variety performance. The disease can cause substantial loss with 50 per cent or more of the crop being affected. Good management, though, can help growers avoid losses entirely.
