Rains will continue to keep in elevated risk levels for FHB in varieties
currently flowering (Kent Co Delaware and similar latitudes in Maryland),
and slightly North. Growers with wheat flowering at this time may consider
an application of a FHB fungicide (Caramba, Prosaro, Proline). Applications
are most efficacious when applications occur from the start of flowering
(50% of MAIN tillers with anthers extruded), through 6 days from the start
of flowering. Efficacy is significantly reduced when applied outside of this
window. Apply in 5 gal/A air and 15 gal/A by ground, 300-350 um droplet
size, with nozzles at least angled forwards 30 degrees. Wheat not yet
flowering is not at risk. Continue to check your wheat and this page for
updates. For more information follow this link:
