Scab risk across the majority of PA remains low early this week, a result of unseasonably cool temperatures. However, for barley that is now heading in western PA, a protective fungicide application may be advised for susceptible or very susceptible varieties. Barley growers in the northern tier of PA should keep an eye on their crops for heading as current weather forecasts predict higher risk for those areas in the near future.
