Wheat in central Illinois is now flowering. The current risk of FHB is low, but this risk will increase if the weather changes to rainy and cloudy with high relative humidity. If the decision to apply a fungicide for FHB management is made, university research has shown that Prosaro and Caramba fungicides are the most effective fungicides available when applied at early anthesis (Feekes growth stage 10.5.1) in reducing FHB disease and DON (vomitoxin) contamination in harvested grain.
Symptoms of FHB are beginning to show up in fields in southern Illinois, but at this time, it is not clear how severe or widespread the disease is.
