FHB Update from ND, 06/27/18

Scab risk has increased for susceptible varieties that are headed or are in the flowering stages of development. Currently, there are several areas of moderate to high risk across much of the state. Scab risk for moderately susceptible varieties is lower, however a pocket of moderate risk exists in southwest North Dakota. I am expecting scab risk in the state to maintain or even get higher in the next few days. Several factors that will contribute to a higher risk include wheat planted on corn residue, rain, prolonged dew periods (into the afternoon hours), and fog. Continue to monitor the growth stage in the field, record field conditions, and apply a timely fungicide.
