Scab risk across the majority of PA remains low through the weekend despite forecasted moisture, mainly because of unseasonably cool temperatures. However, for barley that will be heading across southern and central western PA in the first half of next week, a protective fungicide application may be advised for susceptible or very susceptible varieties. Check your risk level any time at wheatscab.psu.edu.
