Fire Blight
Fire blight is a disease that can infect apples, pears, and certain ornamental species including crabapples, cotoneaster, and mountain ash. Occasionally it may also appear on cherries, plums, Juneberry (also called Serviceberry or Saskatoon), and raspberry. This disease, caused by the bacteria Erwinia amylovora, can damage blossoms, fruit, leaves, shoots, and branches. If it is not controlled, fire blight may kill the entire tree or shrub. Infected tissue cannot be cured, but will need to be removed from the tree to prevent further spread.
