The IPM survey scouts identified foliar diseases in nearly every field visited. Bacterial leaf streak is starting to be noticed on flag leaves in several areas of ND with higher incidence reports in northcentral and northeast portions of the state. Scab has been found in most winter wheat fields. However, growers and Extension Area Specialists have indicated that timely fungicide applications at early-flowering have reduced scab incidence levels. Now is a good time to scout for scab in spring wheat approaching the soft dough stage. More IPM survey information can be found at IPM Survey

Last week the hot, dry and windy weather lessened scab risk as most of the state had a low to moderate risk of scab developing in very susceptible varieties. However, recent rain events will most likely increase the risk of scab in flowering small grains. Monitor the growth stages in your fields and use the scab forecasting models to help decide if a fungicide application is needed.

If you have any questions, contact the Department of Plant Pathology, NDSU, Fargo, ND 58105 (701-231-7627).

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.
