Several wheat fields in Kentucky currently are at the early anthesis stage (Feekes growth stage 10.51) or beyond that stage. Currently, the FHB risk map is showing a medium risk for FHB in some areas of Kentucky. With rainfall in the forecast in the upcoming days, this risk may increase and encompass a larger geography. Because of rainfall, soil is saturated in several fields, making it difficult for ground sprayers to apply fungicides. It is important to note that multi-state research trials have shown that effective fungicides registered for FHB control in wheat have been effective in reducing FHB and the associated mycotoxin DON when applied up to 7 days after the early anthesis stage. Please read all fungicide labels before making any applications to ensure that your crop is still at a stage where fungicides can be applied.
