Winter wheat is approaching flowering and some of the earliest planted barley may be heading this week. Currently, most of the state is at low risk for FHB, but a few pockets of moderate risk are developing in south central and northeastern ND. Most of the state received rain last week and the forecast for this week shows sporadic rain events with high dew point temperatures. As a reminder, the best time to apply a FHB fungicide in winter wheat is at early-flowering (and up to 6-7 days after) and the best time for barley is complete head emergence (and up to 6-7 days after). The most effective fungicides are Caramba, Miravis Ace and Prosaro.
