Wheat in the Eastern Shore of Maryland is flowering (50% of the main tillers showing yellow anthers) or will do so in a couple of days. With no rains predicted over the next 10 days, currently the risk of Fusarium Head Blight is showing up to be low so far. No fungicides are needed to be sprayed if your wheat is currently flowering, especially if you have selected a resistant variety. Barley is already headed in this part of the state and is out of the vulnerability stage for FHB. In case the rain predictions do not turn out to be true for this week (which happens sometimes, given we are in Maryland!!), I will update my commentaries indicating so. In that case head scab fungicides (Prosaro/ Caramba/ Miravis-Ace) at wheat flowering or within 4-5 days of this stage. Up in the North on the western side of the bay, wheat is booting, and still roughly around 1-2 weeks away from flowering. Farmers in these counties (Harford, Frederick, Howard etc.) will be updated about the risk as wheat p rogresses.
