Kansas State University Research and Extension, with support from the Kansas Wheat Commission, recently hosted a webinar on the wheat streak mosaic complex, addressing the significant 2025 outbreak and sharing current best management practices. This special-topic webinar is now available to view on demand via the K-State Agronomy YouTube channel.

Both afternoon and evening sessions were held live on Tuesday, July 29, and featured presentations from specialists across K-State Research and Extension, including the Departments of Plant Pathology, Agronomy, and Entomology. Topics included:
- The 2025 outbreak overview
- Mite and virus biology
- Volunteer wheat control strategies
- Variety selection and genetic resistance

In addition to the webinar, the eUpdate featured a three-part article series in July where we took a deep dive into topics related to wheat streak management.
Week 1: Wheat-free windows and herbicide recommendations
Learn how timely volunteer wheat control reduces risk.

These articles highlight the importance of integrated management, including coordinated volunteer wheat control, careful timing of planting, and strategic variety selection based on resistance to viruses and wheat curl mites and proximity to areas of known risk for curl mites.
Even the best tools have limitations, especially in the presence of mixed infections, early planting, or prolonged high temperatures. Variety performance and risk vary by region, particularly between central and western Kansas.
