Barley is heading in the southernmost regions of Pennsylvania. Be sure to scout for growth stage as there appears to be a good deal of variability across the region due to the dry fall and spring. Risk of scab infection is medium in many Southeast areas now, but keep an eye on your risk forecast as your crop approaches heading.

The best fungicide application window for barley is from 100% heading up to a week later. If you plan to spray for head scab, choose a labeled triazole-containing product (FRAC 3) like Proline, Prosaro, Prosaro Pro, Miravis Ace, or Sphaerex. Do not use a product that contains any strobilurin (FRAC 11).
