The wheat growing season in Nebraska has started and and regular scouting for early disease detection is recommended, and will be especially important this year due to the excessive moisture we've had.
Though relatively small, UNL's Department of Plant Pathology has played a significant role in the discovery of many economically important plant diseases, including most recently, a new fungal pathogen causing Fusarium head blight of wheat. This article is from the 2019 Nebraska Crop Management Conference Proceedings.
This article, from the Proceedings of the 2019 Crop Production Clinics, addresses new and updated product labels for disease management, a report from the Plant and Pest Diagnostic Clinic, changes in the Department of Plant Pathology, and the initial US finding of Fusarium boothii on wheat in Nebraska.
