Fusarium head blight
Posted on: July 11, 2018 by Juliet Marshall
Fusarium head blight (FHB or head scab) is being found in winter wheat and spring wheat.
Fields throughout southern and southeast Idaho are being affected by FHB, everywhere from Glenn’s Ferry through Firth. Some winter wheat fields have white heads caused by take all as well as partial to whole heads bleached by FHB. While it is unlikely that there are any fields still in the vulnerable stages (flowering), at risk fields should be protected with appropriate fungicide application. Fields should still be scouted and infected grain fields identified prior to harvest. DON (deoxynivalenol or vomitoxin) contaminated, infected seed and tombstone kernels can be reduced by increasing the fan speeds on the combine. This can significantly reduce dockage and rejection at the elevator.
