[Fhb-update_ma] FHB Update from VA, 05/01/19

[FHB Updates - Mid Atlantic SWW Region]

There is increased risk of Fusarium head blight (FHB) in some parts of
Virginia, especially near the Northern Neck and Eastern Shore of Virginia.
Wheat in much of the state is flowering, and if a field is in a high risk
area a fungicide application is recommended. Recommended fungicides for
control of FHB and DON contamination include Caramba, Prosaro, Proline, and
Miravis Ace. Do not apply a strobilurin-containing fungicide after the flag
leaf stage since this has the potential to increase DON concentrations in
the grain. To maximize their effectiveness, fungicides for FHB and DON
control should be applied at early flowering or up to one week later.
Fungicides that control FHB and DON will also control foliar diseases
including powdery mildew, leaf rust, stripe rust, and leaf blotch.
