In the previous versions of this publication, the terms "common scald" and "Anjou scald" were used to designate two physiological skin diseases of pears. In this revision, however, these designations have been changed. The term "common scald" has been replaced with "senescent scald", since the disease is associated with aging. The name "Anjou scald" has been replaced with the name "superficial scald", a term which better describes the disease. Since the disorder also occurs on the variety Packham's Triumph, elimination of the varietal designation from the name of the disease is desirable.
