[Fhb-update_ma] FHB Update from MD, 05/30/18

FHB Updates - Mid Atlantic SWW Region fhb-update_ma at scabusa.org

Flowering is all finished across all counties of Maryland now, except for a
few late planted fields in the northern part of MD that may still be
flowering, and with the current high risks of FHB should be sprayed with
Prosaro/Caramba. For most parts, wheat is now in the grain filling stage.
With the showers that we had at flowering, there are high chances of
substantial Fusarium Head Blight incidences this year. Consequently,
tombstones (shriveled scabby kernels) and DON content are going to be a
concern for the growers. To assess the incidence of FHB, you may randomly
pick 20-25 heads of wheat per 1-2 acres and count the spikes having bleached
spikelets. Fields with high incidence rates should be harvested separately
from those with lower incidences. Harvesting from fields with high levels of
FHB incidence should be done with higher fan speeds to remove lighter
tombstone kernels. The farmers are advised to get the DON content analyzed
in the grain before taking it to the market.
