Fusarium Head Blight Update (07/16/20)

Fusarium head blight (FHB) risk continues to be moderate to high for susceptible varieties beginning to flower for much of the state.

Fusarium head blight (FHB) risk continues to be moderate to high for susceptible varieties beginning to flower for much of the state. It appears the risk will stay elevated for several days, especially in areas that received significant rain in the past couple days. While visiting research plots, I observed FHB symptoms starting to show on some of my earliest planted spring wheat, barley and durum (Figure 1). The best time to observe FHB symptoms in the field is 14-21 days after early-flowering in wheat and 14-21 days after barley has headed.
