Apple Scab Alert
May 18, 2015 Kari Peter of Penn State University Extension warned growers of possible apple scab and fire blight infections following the rainy weekend.
“We experienced fire blight conditions from May 5-12 and growers should begin to scout for infections during the coming week. Be on alert for powdery mildew infections, thanks to the dry weather lately. Control measures are needed to manage bacterial spot on stone fruit,” Peter writes.
She says growers must scout for apple scab infections, as well. The best prevention is to protect trees prior to infection risks.
