Request for Help Evaluating the Wheat Fusarium Head Blight Prediction System

Fusarium head blight (FHB) of wheat has been an important problem in Illinois, with recent regional disease outbreaks occurring in 2009 and 2010. The disease causes significant yield loss, and damaged grain is often contaminated with the mycotoxin deoxynivalenol (DON), commonly known as vomitoxin. The disease is best managed through a combination of variety resistance and timely application of fungicides when weather conditions elevate the risk of disease development. In recent years, there has been considerable effort to predict the risk of FHB and the need for fungicide applications in wheat.

The web-based prediction tools (www.wheatscab.psu.edu/riskTool_2010.html) provide daily estimates of disease risk for 25 states east of the Rocky Mountains. This multi-state effort requires considerable resources to maintain, and scientists involved in the project would like to gather some input to justify a continued investment of time, computing resources, and funds to sustain the effort.

If you have used these tools, the developers would like to hear from you. Please take a few minutes by November 30 to complete an online survey (www.hostedsurvey.com/takesurvey.asp?c=2010Us121326) that will help them evaluate, improve, and maintain the system.--Carl A. Bradley
