Rapid analytical methods for wood waste - An overview
1998 - IRG/WP 98-50104
The proper handling of wood after service is a today's problem. Untreated wood could be reused or may be used as fuel. For treated wood special care is demanded to avoid environmental impacts. Thus, analytical methods are requested to detect rapidly whether and to what extend wood is contaminated, covering a wide spectrum of organic and inorganic agents used during the last 50 years. Trad...

Laboratory evaluation of chlorothalonil formulation for stain and mold control on rubberwood and maple
1998 - IRG/WP 98-30175
We evaluated the efficacy of several chlorothalonil and carbendazim fungicides (F1 and F2), etc. in the control of mold and stain fungi on rubberwood and maple. The results showed that these formulations effectively inhibited the selected fungal species such as Aspergillus niger, Penicillium sp., Trichoderma sp. (P71H), Aureobasidium pullulans, Ceratocystis minor (C-188), Ceratocystis pilifera (RW...

Susceptibility of harvested softwoods to infection by sap-staining fungi
2002 - IRG/WP 02-10435
In the UK a field study programme was carried out to compare the susceptibility of softwood timber from five different commercially important tree species to infection by sap-stain fungi. Logs cut from freshly felled Scots pine (Pinus sylvestris), Lodgepole pine (P. contorta var.
latifolia), Sitka spruce (Picea sitchensis), Norway spruce (P. abies) and Japanese larch (Larix leptolepis) were expo...

A comparative study of CCA type C and B treated poles in service
1993 - IRG/WP 93-50001-05
CCA K33 type B and C treated utility poles, 9 pieces of each treatment type, were analyzed for preservative retention after 11 years in use. Borings were taking 1 m above and 0.3 m below the ground line. Also total amount of copper, chromium and arsenic was determined in soil surrounding the poles. The solubility of these active components in soil was monitored by using different leaching procedur...

The shower test method. A leaching test for assessing preservative losses from treated timber under simulated open storage conditions
1993 - IRG/WP 93-50001-04
In the late 1980's against the background of increasing environmental concern a laboratory based accelerated leaching test method for assessing preservative losses-from stored, treated timber was developed by the Dutch organisation for applied Scientific Research (TNO). This test method quantifies the amount of specific preservative components which leach from treated timber under simulat...

Premature decay of CCA-treated pine posts in horticultural soils - An overview
1984 - IRG/WP 1241
The recent discovery in New Zealand of early decay in CCA-treated pine posts set in horticultural soils led to the establishment of a comprehensive research programme. The objectives and outline of this programme are presented together with an overview of research progress to date. Results suggest that premature decay of CCA-treated timber is restricted to material placed in highly cultivated soil...

The dip diffusion treatment of tropical building timbers in Papua New Guinea
1972 - IRG/WP 310
In Papua New Guinea a dip diffusion process using a multi salt preservative developed by C.S.I.R.0. has been in commercial use for 8 years. Over 200 million super feet (236,000 m³ ) of timber has been treated during this period and current rate of treatment is 34 million super feet (80,400 m³ ) of timber per year in 70 licenced treatment plants. The process has been found to be simple to apply, ...
