Wheat Streak Mosaic Virus

Wheat streak mosaic is one of the most economically devastating wheat diseases in Kansas and the Great Plains. The disease is most common in the western portion of the state, with sporadic outbreaks in central and eastern Kansas. 

There are basically only three ways to control the spread of wheat streak mosaic:

  1. Timely removal of volunteer wheat and other grassy weeds.
  2. Avoid early planting, plant after the hessian fly-free date.
  3. Plant varieties with moderate or high levels of resistance to WSMV

Research is headed down the path of genetic resistance, and Kansas wheat farmers should know that help is on the way. However, there are only a few varieties with moderate resistance at the current time.
