Fungi recovered from dump-tank water at a large apple storage and packing facility were assayed for their ability to cause decay. Trichoderma harzianum, a fungus not usually associated with apple maladies, was found to cause a brown firm rot in apples that were wound-inoculated and kept in storage (20 C) for 1 wk.
