Alberta Agriculture plant pathologist Mike Harding has issued a bulletin noting that stripe rust alerts have been issued for Oregon and Montana.
A Jan. 19 Capital Press story says stripe rust has been discovered in Oregon’s Willamette Valley. Oregon State University plant pathologist Chris Mundt and three extension researchers issued an alert Jan. 19 informing growers that they have found stripe rust in early-planted experimental plots and commercial fields, beginning with sightings Jan. 7-12, three weeks earlier than ever previously recorded.
Harding said leaf rust on winter wheat in southern Alberta has also been reported. He said it would be wise to scout winter wheat crops regularly for rusts as the wind trajectories and weather conditions are now putting southern Alberta cereal producers at risk for these diseases.
