Several spring barley fields are starting to head and spring wheat growth stages range from tillering to boot stages. Some of the earliest planted spring wheat may be heading and potentially flowering next week. The greatest amount of scab risk is on the eastern half of the state with another scab risk pocket in northwest ND. Rain is projected several times in the next week, and this combined with high dew point temperatures, will likely increase scab risk for some. Scout spring wheat fields to determine growth stage and start planning a fungicide application at early flowering in areas with the the greatest amount of scab risk. For barley, an application should be timed at complete full-spike emergence. With both spring wheat and barley, scab and DON suppression can still be achieved if a fungicide is applied 3-7 days after early flowering in wheat or full-head in barley.
