Status of the research and development of a new preservative system (EFPL) for pressure treatment of spruce in Canada
1975 - IRG/WP 348
Our work has been to develop a system which would have the stability of the ACA system and the formulation flexibility of the CCA system enabling properties such as fixation of arsenic, water repellency, appearance and cost to be controlled. Our permeability studies of spruce using a method previously developed indicated that an ammoniacal solution of copper arsenate is an excellent candidate for ...

A questionnaire was drawn up by Prof. C. Jaquiot and the members of the IRG were asked to give information on Gloeophyllum trabeum in accordance with this questionnaire. The results of this enquiry are g...

Antagonism to spore germination in Scots pine
1990 - IRG/WP 1458
Germination of Lenzites trabea and Chaetomium globosum spores was observed directly on wood blocks, on water soluble extracts and on organic solvent soluble extracts from pine wood. In all cases pine heartwood was found to be antagonistic to spore germination but pine sapwood varied in its antagonism according to the method of drying. Chromatography revealed that extracts from antagonistic wood di...

Resistance of various wood species against decay by Coniophora cerebella (Pers) Duby and Lenzites trabea (Pers) Bres
1976 - IRG/WP 142
Both fungi, Coniophora cerebella and Lenzites trabea, are important destroyers of timber. Coniophora often occurs inside buildings and Lenzites trabea has been observed on southern facades of buildings, on balconies and window frames. In most instances that we investigated coniferous timber had been decayed. But both species are known to attack also various hardwoods. For this reason tests similar...
