[Fhb-update_ma] FHB Update from MD, 05/06/19

[FHB Updates - Mid Atlantic SWW Region]

With the recent showers in the state the risk of Fusarium Head Blight
appears to be high. In the Eastern Shore wheat is currently flowering (50%
of the main tillers showing yellow anthers). Growers with their wheat
flowering are advised to spray head scab fungicides (Prosaro/ Caramba/
Miravis-Ace). These fungicides do not need to be tank mixed with another
product for spraying. The fungicide products should be applied at the full
rate recommended by the manufacturers. Strobilurin containing fungicides
should not be sprayed at this stage. Aerial application at a rate of 5
gallons per acre or ground application at 15 gallons per acre with 300-350
um droplet size is recommended. Spray nozzles should be angled at 30°-45°
down from horizontal, toward the grain heads, using forward- and backward
mounted nozzles or nozzles with a two directional spray, such as Twinjet
nozzles. In the Northern counties, we are still around 7-10 days away from
flowering.
