Wheat Fusarium Head Blight Prediction Center - 2009

The Wheat Fusarium Head Blight Prediction Center and forecast tool is now active for 2009. The site can be accessed at I will again be writing state commentary for this site and will update growers on wheat growth stages in relation to our observations of wheat diseases. We will have an active wheat program for 2009, with our disease assessments commencing at Zadoks 30 (Feekes 4-5, or jointing) and continuing through our head blight assessments at approximately soft dough. We recently wrote for the Wisconsin Crop Manager an updated article on making foliar fungicide decisions based on current knowledge of disease thresholds for diseases like rust, powdery mildew, and Septoria leaf blotch. That is available here.
