Fusarium Head Blight Update – 9 June 2010

While most of the winter wheat crop is past flowering in many parts of the state, we are continuing to monitor the Fusarium head blight risk especially for later maturing wheat or spring wheat in the state. Today’s risk map has shown a change in the risk of infection in pockets of state since we have seen heavier rainfall amounts the past week in many areas. There are several pockets that are in the medium to high risk of infection but it is important to pay close attention to the wheat growth stage regarding fungicide applications (see previous postings and also the Wisconsin Crop Manager for further information).
