Wheat in Virginia is at or near flag leaf emergence. Currently, scab risk in
the region is low but growers should consult the FHB prediction tool as the
crop gets closer to flowering. Powdery mildew has been reported from
throughout the state, and leaf and stripe rust have been reported just south
of Virginia in North Carolina. Fungicides containing a strobilurin should
not be applied once the head begins to emerge but are a good option for
control of foliar diseases as the flag leaf emerges. Late applications of
strobilurins can increase DON (vomitoxin) if scab infections occur during
flowering. Triazoles including Caramba, Proline, and Prosaro are good
options for scab control and will also control late-season foliar diseases.
