Bull's eye rot of Bosc pear (pathogen not identified on slide).

Part of OSU Extension Plant Pathology slide collection, 1986 or so.

See:

Apple (Malus spp.) - Anthracnose (Bull's-eye Rot)

Pear (Pyrus spp.) - Storage Rots

Note Neofabraea vagabunda (formerly N. alba) has been found in both small cankers and pruning stubs in pear growing regions of Oregon. However, this was the most common species isolated from bull's eye rot lesions on pear fruit.

  • Be cautious when you apply pesticides. Know your legal responsibility as a pesticide applicator. You may be liable for injury or damage resulting from pesticide use.
