Decay causing fungi

Use Apply by dipping or coating to lumber, timbers, fence posts, poles and other wood members for protection against termites and decay causing fungi. 

WOLMAN Treat OO wood preservative shall be used only for field treatment of previously WOLMANIZED pressure treated lumber, piling or plywood to help protect against decay causing fungi and termite attack. It conforms to AWPA Standard M-4. 

Soft rot is a type of decay caused by ascomycetes and Fungi Imperfecti. The term soft rot was proposed by Savory (54) for a form of fungal decay where characteristic chains of cavities with conical ends were produced within wood cell walls. He recommended that the term soft rot should be used for decay caused by cellulose-degrading microfungi to distinguish it from the brown and white rots caused by the wood-destroying basidiomycetes. ... 

It was later discovered that some soft-rot fungi caused cell wall erosion, in addition to forming cavities (55-57). Today soft rot is commonly used to describe all forms of decay caused by ascomycetes and Fungi Imperfecti. Degradation of wood by ascomycetes such as species of Daldinia, Hypoxylon, and Xylaria is, however, often considered as white rot (58-60). A recent study on wood decay by several species of the mentioned genera show that they have characteristics of white rot as well as soft rot (61). 

Biological Attack. Wood is subject to decay caused by certain types of fungi. In extreme cases, such as in tropical climates, unprotected timber may be destroyed in a few months. Keeping wood adequately dry (less than 20 percent moisture) minimizes fungal damage. Structural timber should be protected from the weather by a well-ventilated shelter, and wood members should not be framed close to the ground. 

Exterior Millwork Apply by dipping, flooding or brushing to exterior millwork and other wood products for protection against wood decay, mold and stain causing fungi. 

In practice, the situation isn t quite that simple. DNA samples taken from a victim are almost certain to be contaminated with DNA from fungi or bacteria. Certain dyes can combine with restriction enzymes, causing them to cut in the wrong places. Finally, DNA may decay in a warm or moist environment.
