With the wet soils and large amounts of rain that have swept through Alberta, leaf disease in cereal crops has come to the forefront. Growers have been bringing barley and wheat in for me to look at and they are full of disease. Tan spot and net blotch have been two of the diseases I have seen in the Standard area.
The plant disease triangle is complete with the perfect environment and the pathogens are present and the host crops are susceptible. Scout your fields early and right until flag leaf to watch for those yield robbing leaf diseases.
