This particular disease will only infect plants that are part of the Rosaceae family: apple tree, pear tree, cotoneaster, rowan or mountain ash ( Sorbus), hawthorn ( Crataegus), photinia ( Photinia or Stranvaesia) and firethorn ( Pyracantha). The Erwinia amylovora bacteria is what causes fire blight.
