| dc.description.abstract | Cereal crops in Saskatchewan can suffer a number of diseases that reduce yield and quality. A disease survey was conducted in 2013 to identify pathogenic agents and assess disease severity on oat, canaryseed, barley and winter and spring wheat. Crown rust was detected at trace levels in four of 32 oat crops and the most common leaf spotting pathogens were Pyrenophora avenae and Stagnospora avenae, similar to previous years. On canaryseed, Septoria triseti was observed from plating of leaf samples and appeared to be highest in west-central SK and lowest in the north-east. Fusarium avenaceum was identified from plating of seeds in four of 26 crops, but only at low levels. In barley, only two crops were affected by stripe rust, but leaf spots symptoms observed on most crops, most commonly caused by Cochliobolus sativus and Pyrenophora teres; Septoria passerinii was identified in a few samples. Severe stripe rust infection was observed in seven of 89 winter wheat crops, but 60 crops were stripe rust-free. In winter wheat fusarium head blight was generally low in most regions of SK, except near Outlook, where severity was much higher. In spring wheat, stripe rust infection was observed in eight of 17 crops and was severe in one crop. | en_US |
