Wood Rots

  • Ervin H. Barnes


Wood rots may be described as root, butt (Fig. 52-1 A), stump, trunk, or top rots to indicate that portion of the tree which is attacked. The diseases of these areas are not exclusive. The fungi which cause them attack most any part of the tree. Rots are also described as sap rots or heart rots (Fig. 52-3) to indicate the tissues attacked within the tree. Some organisms which cause a rot of the dead heartwood cannot attack the living sapwood. Such organisms are pathogenic but are they also parasitic? Some of the fungi which cause wood rots, such as Polyporus versicolor (Fig. 52-1 B), are called slash fungi and occur primarily on discarded timber, diseased wood, trash from cutting operations, and fallen trees. They are significant in the destruction and reduction of such slash and are, therefore, beneficial.
