University of Nebraska-Lincoln Extension: Historical Materials
Host range, symptoms, disease cycle, and control options for wheat soil-borne mosaic disease are discussed.
Wheat soil-borne mosaic virus affects wheat (Triticum aestivum L.) growing primarily in central, eastern and west central Nebraska. This disease occurs annually; however, its effect on crop production in Nebraska varies from year to year due to variety selection, cropping practices and environmental conditions favoring disease development. In years when spring temperatures remain cool for extended periods, the virus remains active in infected plants, enhancing symptom development and increasing yield loss. The virus reduces tillering and affects kernel weights and test weights.
