English

Subject field(s)
  • Plant Diseases
  • Xylology (The Study of Wood)
DEF

The decomposition of wood by fungi ...

OBS

Unlike stain, causes a softening and loss of wood.

OBS

The terms "decay" and "rot" are more or less interchangeable, though rot generally implies a more advanced and obvious stage, and as it designates both causal organism and its effects is the key term for specifying types, i. e. dry rot, soft rot.

OBS

"Rot" refers to a dry type of pathological modification, whereas "decay" refers to a wet and damp type of pathological modification; thus, dry rot and wet decay.

OBS

rot; decay: terms standardized by ISO.

OBS

decay: term standardized by the Canadian Standards Association.
