Severe Apple Scab Affecting Pennsylvania Crop

Dr. Henry Ngugi, in the Department of Pathology at Penn State University, said he has recently seen two commercial orchards with complete apple scab control failure in Pennsylvania. “In one of the blocks where I obtained samples, an entire crop of ‘Fuji’ is so heavily damaged that it may not be accepted for juice,” he said in a recent Fruit Times newsletter. “This is a 30-acre block that was subjected to a textbook spray program typical for fresh-market apples in the eastern U.S. And yet, this was not the worst diseased of this grower’s blocks. A Rome block nearby is heavily defoliated, with the few remaining leaves covered with sheet-scab, and the few fruit still on the trees being heavily cracked.”
