Pockets of Western and Northeastern Pennsylvania show medium to high risk of infection at this time. Growers of barley in these areas should monitor crop development and plan to spray a fungicide if they are approaching heading. Caramba and Prosaro (Group 3) or Miravis Ace (Group 3 + 7), give good control of scab as well as most leaf and head diseases. They do not need to be tank mixed with another product to control these diseases. Spray nozzles should be angled at 30° down from horizontal, toward the grain heads, using forward- and backward mounted nozzles or nozzles with a two directional spray, such as Twinjet nozzles. Most wheat in the area is at this time too young to spray for scab, but scout regularly to monitor for leaf diseases and crop development.
