[Fhb-update_ma] FHB Update from DE, 05/21/13

[FHB Updates - Mid Atlantic SWW Region]

Risk levels for FHB have returned to low for the majority of Delaware;
however, weather forecasts indicate increased temperatures and moderate
chances of rain throughout the week. This may increase FHB risk levels in
some areas. Growers are encouraged to continue to monitor their wheat as it
enters flowering and apply appropriate fungicides if needed at Feekes'
10.5.1 (early flowering at the beginning of anthesis). Growers have a 3-5
day window to apply fungicides after wheat has entered Feekes' 10.5.1.
Fungicides applied earlier or later will not provide adequate suppression of
FHB. Fungicides containing a group 11 active ingredient are not recommended
for control of head scab.
