There is a high risk for scab for susceptible spring wheat varieties in several areas across North Dakota. In addition to elevated scab risk levels in northwest and southeast ND, new pockets of elevated scab risk formed in east central and southwest ND. Over the past couple days, several acres of wheat received a fungicide and it is likely more acres will be sprayed with a fungicide this week. If a moderately resistant variety was sown, scab risk f is moderate to high for a pocket in southeast and southwest North Dakota. Rain and high humidity this week (in the forecast) will likely maintain a moderate to high risk for the most problematic areas.
