Small Grain Disease Forecasting Model



June 22, 2015 The IPM survey scouts identified tan spot in 45% of the fields. However, severity still remains relatively low. Stripe rust was only detected in approximately 11% of the fields and in some cases stripe rust lesions were detected on the flag leaf. Continue to monitor stripe rust, especially in later planted spring wheat fields. Scab risk has increased for a large portion of southern North Dakota (south of I-94). Additional areas of moderate to high risk are on the eastern side of the state. With the recent rains and likelihood of more rain in the future, producers should consider timely fungicide applications. For wheat, a triazole fungicide applied at early-flowering is most efficacious, and for barley, the optimum timing is at full head.

Small Grain Disease Forecasting Model

Close up of wheat field bannerThe NDSU Small Grains Disease Forecasting Model assists producers in estimating the possibility of disease in their crops and gives recommendations as to possible preventative applications and times for these applications. This is done in conjunction with NDAWN weather station locations within North Dakota and sections of western Minnesota and eastern Montana.
