- (1) Moisture content of the wood sufficient to support the growth of wood-decay fungus, as determined through the use of a moisture meter; and
- (2) The presence of mycelial growth or characteristic damage from wood-decay fungi.
- (b) A moisture content in the wooden members of a structure in excess of 20 percent of a dry weight basis shall be recognized as an indication that some steps should be taken to control the moisture level of the affected member(s).
- (c) Pesticide applications for the control or prevention of wood-decay fungi may only be performed after informing the property owner or their authorized agent in writing of the biology and conditions supporting the growth of wood-decay fungi. Such notice shall include an evaluation of the condition of the structure, including the moisture content of the wooden members to be treated as determined with a moisture meter, and a statement as to whether or not such condition(s) will support the growth of wood-decay fungus.
