What you describe is called gummosis. Gummosis is a general, nonspecific condition of stone fruits (peach, nectarine, plum and cherry) in which gum is exuded and deposited on the bark of trees. Gum is produced in response to any type of wound, regardless of whether it is due to insects, mechanical injury or disease. You'll need to inspect your tree for insects or signs of diseases and you may need to put your tree on a preventative spray program beginning next winter and continuing through the spring.
