Wheat Scab Update-April 12, 2018
This is the first North Carolina small grain scab risk commentary for the 2018 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, several wheat varieties have headed and will flower soon. Barley will soon head in the Coastal Plain.
Currently, scab risk is low in all the wheat- and barley-growing areas of NC, with the exception of some coastal areas. The forecast holds only a little rain, which means 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 approximately 6 weeks for scab risk in NC.
