Potential toxicants for controlling soft rot in preservative treated hardwoods. Part 4: Evaluation of combined diffusion and toxicity
1979 - IRG/WP 2129
A large number of inorganic and organic preservatives were evaluated as potential soft rot control chemicals, by their degree of inhibition of fungal growth after allowing them to diffuse through a 6 mm thick wood slab. The tests were inoculated with wood powder from soft-rotted CCA treated poles. Pentachlorophenol was unable to diffuse quickly through the wood slab, although formulations with hex...

Preliminary studies on cellulase production by selected Basidiomycetes and the effect of copper-chrome-arsenate on these enzymes
1980 - IRG/WP 1122
The growth of wood-destroying fungi on ligno-cellulosic materials depends on the production of many enzymes, of which probably the most important is the multi component cellulase system. Within this system, at least three different kinds of enzym are believed to be involved in crystalline cellulose decomposition. These are endo-1,4-glucanase, exo-1,4-ß glucanase and ß-glucosidase. Most of the re...

The growth and behaviour of Australian isolates of dry rot fungi, mainly Serpula lacrymans (Schum. ex Fr.) S.F. Gray. A comparision with the world literature
1983 - IRG/WP 1190
In Australia Serpula lacrymans occupies a rather unique environment, being restricted to growth within basal regions of buildings containing masonry. Its rate of timber attack in these situations appears to be far faster than that experienced in other parts of the world. Therefore the question arises as to how Australian isolates (particularly 16508 which has become a "standard" test fungus for so...

On the laboratory use of X-rays in timber decay evaluations
1981 - IRG/WP 2144
The paper reports the results of laboratory experiments on the X-raying of some Pinus radiata sapwood blocks infected with Serpula lacrymans to determine the effect of density and moisture content on the absorption of X-rays by wood. It is concluded that with increasing moisture content there is a very marked increase in time required to pass a constant quantity of X-rays through a test block and ...
