[Fhb-update_ma] FHB Update from VA, 04/22/19

[FHB Updates - Mid Atlantic SWW Region]

Most of the wheat crop in Virginia is currently between flag leaf emergence
and heading with some wheat close to the flowering stage. As wheat reaches
the flowering stage, it is susceptible to infection with FHB, and this is
the critical stage for making fungicide applications. Currently, the risk
for FHB infection is low throughout Virginia. In addition, the 3-day
forecast indicates risk will remain low. Recommended fungicides for control
of FHB and DON contamination include Caramba, Prosaro, and Miravis Ace, and
the optimum application timing is early flowering. Do not apply a
strobilurin-containing fungicide after the flag leaf stage since this has
the potential to increase DON concentrations in the grain.
