The few winter wheat acres in North Dakota are headed out or in the flowering stages. Some of the earliest planted spring wheat has headed and will likely enter early flowering stages in the next 7 days. Presently, scab risk for susceptible varieties is low with a few pockets of moderate risk (northeast ND). Rain and high humidity from this past weekend will likely elevate scab risk in southeast ND. Another chance of sporadic rain may occur towards the end of the week, which may also contribute to elevating scab risk. Continue to monitor the growth stages in the field, keep note of field conditions (ie: morning dews), and apply a FRAC 3/DMI/Triazole fungicide at early flowering when warranted.
