Eslyn, W.E.; Bultman, J.D.; Jurd, L. 1981. Wood de-
cay inhibition by tropical hardwood extractives and related
compounds. Physiology and Biochemistry. 71(5):521-524.
Describes the impregnation of sterilized pine blocks
with extractives obtained from tropical hardwoods (ob-
tusaquinone, obtusastyrene, or lapachol) and one synthetic
compound (2-benzyl-4,6-di-t-butylphenol). The treated
blocks were exposed to the wood decay fungi, Coriolus
versicolor, Gloeophyllum trabeum, or Poria placenta. Ob-
tusastyrene and obtusaquinone were most effective against
the brown-rot fungi. Lapachol was effective at its highest
concentration only against P. placenta. The synthetic com-
pound reduced all decay-associated weight losses. Chemical
sterilization resulted in increased decay by G. trabeum and
P. placenta on treated wood, but no statistical difference
was noted on the control blocks.
FAO. 1973. Forestry and forest industries development
program in Paraguay. Wood preservation. FAO Rep.
FO:SF/PAR 15. Documento de Trabajo. 7:124.
Presents the results of trials with 32 Paraguayan wood
species to determine their suitability for treatment by the
vacuum/pressure and hot- and cold-bath methods. The
majority of the species tested proved suitable for the vac-
uum/pressure process, while 16 species could be suitably
treated by the hot- and cold-bath method. The main ob-
ject of the trial was to find timbers suitable to replace Ce-
drela spp. and Tabebuia spp., which make up nearly 70
percent of the wood used in local markets in Paraguay.

crossties in British Honduras. Tropical Woods. 7:30-32
Several native woods were tested as crossties: these lasted
3.5 to 6 years. All woods tested were untreated or were
only surfaced brushed with preservative.

French, D.W.; Tainter, F.H. 1973. Comparative de-
cay resistance of Chilean woods. Forest Products Journal.
23(8):49-51.
Gives the results of soil/block and agar/block tests of the
resistance of 19 commercial wood species to Lenzites tra-
bea and Polyporus versicolor. Fitzroya cupressoides and
Nothofagus obliqua were classed as highly resistant and
N. pumilio as resistant. It is noted that house builders are
tending to use nonresistant timbers (e.g. N. dombeyi) on
an increasing scale, without treatment, as the more resis-
tant species become more scarce.

Boletin de la Sociedad Mexicana de Micologia. 11:35-98.
Describes a study of 67 species, based on herbarium mate-
rial. Most subtropical forests had the most species, followed
by Abies forests, tropical, and Pinus/Quercus forests. A
key is provided for identification of the main genera and
species.

Posts treated with a double diffusion method of 50 per-

durable, and had an average durability of 17 years, as com-
pared to 2 years for untreated posts.
