FHB Update from SD, 06/17/19

A good proportion of winter wheat in South Dakota is now in bloom (anthesis) or past bloom as of the week of June 17. The Fusarium head blight (FHB) predicted risk has not changed from last week (remains low) because of generally low relative humidity, which is the predictor of FHB. Scouting and watching the weather is encouraged until wheat is done flowering when the risk for scab considerably goes down. Most of the wheat fields scouted looked disease free especially the flag leaf and the leaf below flag leaf.
