Wheat in Kentucky is anywhere between boot and flowering. Currently, the risk of Fusarium head blight is low, but forecasted rain in the upcoming days may change that risk. Stripe rust is present on susceptible varieties. An application of Caramba or Prosaro at Feekes 10.5.1 (when anthers begin to extrude out of the middle part of the wheat head) will provide some protection against both Fusarium head blight and stripe rust.
