Our colleague, Don Hershman, said that the Fusarium Head Blight (Head scab) Risk Management Tool has been updated and is available at: http://www.wheatscab.psu.edu/riskTool_2009.html
The tool provides a general risk level for wheat in a given area.
Once into the tool, identify what date you want to select (such as today).
Then identify the wheat model (spring wheat or winter wheat).
Finally, select the state in the map that applies.
A color-coded map will appear with green being little risk, yellow being medium risk and red being high risk. This model can help when deciding to make a preventative fungicide application.
