With the recent wet period and warm temperatures, FHB risk in the state of
Maryland continues to be very high. Growers having their wheat flowering now
are advised to spray triazole fungicides (Prosaro/Caramba) for FHB. Aerial
application at a rate of 5 gallons per acre or ground application at 15
gallons per acre with 300-350 um droplet size and nozzles angled down 30 to
45 degrees from horizontal is recommended. If flowering has finished,
fungicide spray will not help to reduce FHB and DON contamination of grains.
Do not spray strobilurin-containing fungicides.
