July 7, 2015 Stripe rust has moved onto flag leaves of spring wheat. Fungicides that were applied at flag leaf timing have been effective in managing this disease. Stripe rust will continue until consecutive daytime temperatures above 90 and/or nighttime temperatures above 65 occur. Other diseases that have been reported included bacterial leaf streak in wheat and barley. Remember fungicides do not have adequate activity on bacterial diseases. Most of the wheat is past flowering in southern North Dakota and several fields received a fungicide application. Wheat in the northern tier of the state is at heading or flowering and fungicides should be considered in areas of elevated scab risk. Most areas along the Canadian border have an elevated risk if a susceptible variety was grown. Continue to monitor the weather and wheat growth stages in your fields.

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