Look carefully at the peach tree. The leaves, bark and fruit all give information about the tree's illness. Dark spots on the fruit, dead blossoms and shoots, cankers, also called mummies, that turn into brown spots, curled leaves and cracks in the fruit all signify the potential for various diseases.
Look at other trees in the orchard, or ask about other trees in the area to find out about diseases in those trees. Think about the weather of the current and past seasons, because rain and drought can play a part in peach tree diseases. Look over the fertilization and pesticide application history for any information to help determine what type of problem the tree has.
After gathering as much information as possible, get an expert opinion. An arborist, horticulturist or extension agent at the local extension office can help determine the type disease plaguing a peach tree. The expertise a professional provides in terms of treatment and management ensures the health and well-being of the tree and helps prevent disease from spreading to other trees.
