North Carolina Wheat Scab Risk Update

— Written By

This is the first North Carolina scab risk commentary for the 2017 scab monitoring season. In most of NC, wheat is still 2-6 weeks from the period when Fusarium infects heads, which is flowering. In the southern part of the Coastal Plain, the earliest wheat varieties are heading this week, but most of the crop is at flag leaf emerged or just emerging. Barley is heading in the Coastal Plain. Currently, scab risk is low in all the wheat- and barley-growing areas of NC. The forecast holds only a small amount of rain, suggesting that risk will remain low for the next 10-14 days. There is no need to treat for scab when risk is low. Updates will be provided for the next 6 weeks.
