The Fusarium Head Blight Prediction Center estimates disease risk for wheat and barley.

Wheat in Northwestern Kansas, as well as areas of the Midwest (Central IN, IL and OH) is now at or approaching growth stages that are vulnerable to Fusarium infection. Growers in these areas should be watching weather for additional periods of humid, rainy weather that could stimulate disease. Be sure to check with local university extension or other consultants to discuss disease risk.

Tips of using the tool: The tool shows the disease risk for susceptible wheat varieties for today’s date. You can select earlier assessment dates by clicking on the calendar menu at the top of the risk map. The risk maps based on 2, 4 or 6 days of forecasted weather are accessed by selecting the buttons to the right of the date selection menu. Use the menu button on the upper left corner of the map to active risk maps for wheat varieties with other levels of genetic resistance to Fusarium head blight.

Please note that the colors showing the different levels of disease risk changed this year. The lowest level of disease risk is now represented as yellow on the risk map. Moderate and high levels of risk are represented orange and red, respectively.
