Incidence

Spot blotch, seedling blight, root rot and head blight are often serious and widespread and are caused by the same fungus. The fungus overwinters in seed, barley debris and soil. All barley seed should be treated with fungicide (refer to OMAFRA Publication 812, Field Crop Protection Gude).

To reduce the severity of spot blotch and head blight, avoid growing barley after barley, wheat or grasses. Early planting helps avoid serious disease in July. Disease is less severe on barley grown in combination with oats.
