FHB risk is increasing in Virginia and will continue to increase over the
next several days. Risk is highest on the Eastern Shore, but susceptible
varieties such as Shirley that are flowering over the next week will be at
moderate to high risk in many portions of the state. Growers should monitor
the FHB risk tool as their wheat crop begins to flower and consider applying
a fungicide if risk is moderate to high. Wheat that has completed flowering
is no longer susceptible to infection. Fungicides should be applied at early
flowering or up to one week later. Do not apply a strobilurin-containing
fungicide since this can increase DON contamination. Recommended fungicides
include Prosaro, Caramba, and Proline.
