Leaching of CCA from Pinus patula during marine trials in the southern hemisphere
1991 - IRG/WP 4167
Pinus patula stakes were treated with CCA to retentions of 31 kg/m³ salts, and were sited in the sea of Port Alfred, South Africa, for two years. Samples were then removed to the laboratory and analysed as before for copper and arsenic. Prelimiary data showing CAA losses from these stakes in the marine environment showed that CCA was longitudinally leached from them, and was also transversly redi...

The influence of formulation on the behaviour of LOSP's during industrial impregnation of spruce
1986 - IRG/WP 3387
Evidence is presented that the comparative behaviour of two LOSP formulations during impregnation treatment of spruce cannot be predicted purely on the basis of their physical characteristics (viscosity, surface tension and contact angle) nor on the extent of their 'passive' penetration into pine sapwood....

An investigation of organotin compounds in treated wood using Mössbauer spectroscopy
1983 - IRG/WP 3249
The influence of sample preparation on the 119mSn Mössbauer spectrum of tributyltin chloride in ponderosa pine was investigated. Initial studies with sawdust and compressed discs concluded that the latter were clearly superior. Further studies showed that compressed discs prepared from 0.4 g of treated wood and 0.1 g of cellulose were robust and gave excellent Mössbauer spectra. The possibility ...

Leaching Characteristics of Copper in Copper Treated Wood
2003 - IRG/WP 03-30316
The leaching characteristics of copper in copper treated bamboo and other wood species such as slash pine and poplar has been conducted in this paper according to AWPA M11-87 standard, the result indicates that:
--Copper fixation rate of salts from organic acids such as citrate and oxalate and malate is less than other non-organic acid formulations.
--Copper fixation rate of oven-dried bamboo sa...

Xenon simulation of natural weathering of external joinery preserving - Finishing systems
1992 - IRG/WP 92-2412
Semitransparent wood stains ('lazures') for external joinery have developed by means of product combination towards complete wood finishing systems that are easy to applicate, have a good weathering resistance and low maintenance cost. The search for enhanced formulations and the possibilities to standardize these products or treatment systems are always facing long periods of we...

A laboratory bioassay on the termiticidal efficacy of a chlorothalonil formulation and a chlorothalonil plus chlorpyrifos formulation to Mastotermes darwiniensis Frogatt
1993 - IRG/WP 93-30004
Results of a laboratory bioassay on the efficacy of two preservative formulations (chlorothalonil in oil; chlorothalonil plus chlorpyrifos in oil) to the Australian subterranean termite Mastotermes darwiniensis Froggatt are given. Specimens of Pinus radiata D. Don sapwood were treated to three retentions of each formulation to achieve 3.2, 6.4 and 12.8 kg/m³ of chlorothalonil a.i. and 3.2 + 0.2, ...

Towards a colour assay of wood degradation
1982 - IRG/WP 2180
A colour assay for the enzyme catalase is described. Since the activity of this enzyme has previously been shown to be correlated with degree of wood degradation as determined by other methods, this assay may provide a rapid quantitative indicator of superficial and internal wood decay....

European laboratory termite testing
1986 - IRG/WP 1299
As with all testing of wood preservatives the evaluation of the resistance to termites of treated wood requires methodology which is approriate to, and can be readily extrapolated to, the practical situation. Thus not only must the variations in possible treatment systems be taken into account (eg dip, brush or pressure application) so too must the range of termite species and the type of exposure...

Evaluation of some polyurethanes as protective marine coatings for wood
1985 - IRG/WP 4115
Several polyurethane formulations were evaluated in the marine environment as possible replacements for Irish felt used on U.S. Navy minesweepers as a marine borer barrier between the main wooden hull and an outer, wooden sheathing which covers it. Pine panels coated with the candidate materials were tightly juxtaposed with untreated pine baitwood to simulate the hull/sheathing configuration, the ...

Effect of media composition on the antagonistic properties of Trichoderma spp. against wood decay fung
1992 - IRG/WP 92-1538
Most screening of potential biocontrol agents of wood decay fungi has previously been undertaken using artificial media. Similarly experiments designed to evaluate the mechanisms involved in antagonism between biological control agents and target fungi, have largely been carried out in conditions which do not accurately reflect the nutrient status of wood. This paper examines the influence of nutr...

Influence of variable lignin content on brown rot decay of wood
1987 - IRG/WP 1320
Compilation of published data and new experiments with brown-rotting fungi on different timber species suggest that their decay activity, in contrast to soft rot and white rot fungi, is not greatly influenced by the type or amount of lignin present....
