Pyracantha scab is caused by a fungus that overwinters in infected leaves, twigs, and berries. Young leaves and berries are most susceptible to infection. Olive green to black spots develop on leaves, twigs and fruit. Infected leaves may turn yellow or red and fall off prematurely.

Management Options

Use Integrated Pest Management (IPM) for successful plant problem management.

  • Pruning in dormant season to remove dead wood and foliage.
  • Plant resistant cultivars: for yellow berries, ‘Shawnee’ and ‘Aurea’; for orange berries, ‘Mohave’, ‘Orange Glow’, or ‘Teton’; for red berries, ‘Watereri’, ‘Government Red’, ‘Navaho’.
  • Rake and destroy fallen leaves and fruit.
