Plain language summary
In 2019, 58 barley fields and 54 oat fields were assessed for leaf spot diseases in Manitoba. In Manitoba, the level of leaf spot diseases in barley and oat was low in 2019, partially due to dry weather conditions during the growing season which were not favourable for the development of leaf spot diseases of barley and oat. Spot blotch and net blotch were the principal diseases found in barley whereas leaf blotch was the predominant disease in oat fields.
Abstract
In 2019, 58 barley fields and 54 oat fields were assessed for leaf spot diseases in Manitoba. In Manitoba, the severity of leaf spot diseases in barley and oat was low in 2019, partially due to dry weather conditions during the growing season which were not conducive for the development of leaf spot pathogens. Cochliobolus sativus (spot blotch) and Pyrenophora teres (net blotch) were the principal pathogens found in barley whereas Pyrenophora avenae was the predominant pathogen isolated from commercial oat fields.
