IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 4: Report of second inspection (12 months) in Australia
1979 - IRG/WP 448
Previous reports have presented full details of the treatment and installation of the test specimens in Sydney Harbour during December, 1977, and of the results of the first (6 months) inspection made during June, 1978. At the June inspection it was apparent that the plastic tubing used to make up the frames from which to suspend the specimens was inadequate for the job and not strong enough to su...

A new accelerated field test for termites
1983 - IRG/WP 1178
A new accelerated field test method for termites is described. Two series of tests were conducted with this accelerated method and the results were very encouraging....

Isolation and identification of bacteria from CCA-treated eucalypt power transmission poles
1987 - IRG/WP 1317
Bacteria have been isolated from CCA treated Eucalyptus maculata poles which possessed characteristic bacterial decay patterns. Cultures were isolated on a number of different media which had been inoculated with a splinter of degraded wood. Primary tests indicated that most isolates belonged to the genera Pseudomonas and Bacillus. The species Pseudomonas cepacia was most frequently isolated....

Leaching of CCA preservative from treated timber in marine environment
2001 - IRG/WP 01-30254
Knowledge on the amount of preservatives leaching out of treated wood is essential to optimise the chemical loading in various species of timber required for different end uses. In order to gain more insight into this aspect, the residual CCA content in 40 treated timber panels belonging to 14 species removed on destruction by marine organisms from a series of durability tests conducted in Kochi w...

Volumes and weights of different CCA-C treated wood poles, anchor logs and crossarms of REB at air dry condition
1996 - IRG/WP 96-40073
Researches revealed the unit volumes and weights at air-dry condition (12% MC) of different poles, anchor logs and crossarms species of REB from this world. The softwood products are lighter than hardwood products. Inversely the unit volumes of softwood poles are higher than those of hardwood poles. Red pine (Pinus resinosa), radiata pine (Pinus radiata), blue pine (Pinus wallichiana), fir (Abies ...

Copper-resistant fungi on pressure impregnated wood in Denmark
1994 - IRG/WP 94-10078
The occurence of Amorphotheca resinae Parbery and its asexual stage Cladosporium resinae (Lindau) de Vries on CCA and CCB treated wood has previously been shown. In the autumn 1993 some other blue stain fungi were found on CCP and CCB treated pine timber, such as Ophiostoma minus (Hedgc.) H. and P. Sydow, Ophiostoma pilifera (Fr.) H. and P. Sydow and Ophiostona piceae (Munch) H. and P. Sydow. The ...

Leaching of CCA components from treated wood under acidic conditions
1993 - IRG/WP 93-50004
The leaching of CCA components from treated wood under acidic conditions were investigated. Western hemlock treated with three types of CCA and two levels of target retention was subjected to leaching at four different levels of pH. After leaching tests, leached samples were subjected to laboratory decay and soft rot tests. The amount of CCA components leached was dependent on acidity of leaching ...

Status of wood preservation in India
2005 - IRG/WP 05-30386
Wood, despite the advent of other modern materials, continues to play an important role in man’s day to day life. Usage of wood ranges from fuelwood to engineered wood products and demand for it is increasing which has resulted in depletion of forests and diminishing wood supplies. Future needs are required to be met from plantation timbers after adopting processing technologies for their life...

Artificial drying of impregnated wood
1987 - IRG/WP 3448
Sawn timber (Pinus Sylvestris) of dimension 50x150 mm was impregnated with CCA by a full-cell process. The timber was then dried in a conventional kiln or a special vacuum kiln where the timber was dried by circulating superheated steam. Drying time was 16 days and 2 days respectively. The aim of the investigation was to compare the physical appearence of the wood after drying by the two methods w...

A novel defaunation method of the protozoa to investigate cellulose metabolism in Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae)
1994 - IRG/WP 94-10050
The largest protozoa in the hindgut of workers of Formosan subterranean termite, Coptotermes formosanus Shiraki, was selectively eliminated by forced-feeding on low-molecular weight cellulose (LC) with a mean DP of 17. Although one week's feeding on LC caused perfect disappearance of Pseudotrichonympha grassii Koidzumi, the selective defaunation method itself had no detrimental effect on ...

Inhibition of wood decay and termite damage by calcium precipitation
1996 - IRG/WP 96-30111
Fungal decay of wood in service, especially brown rot, results in billions of dollars (US) of losses annually. Recent environmental restrictions, both U.S. and international, are limiting or eliminating the use of broad spectrum biocides for wood preservation, primarily due to problems with disposal. In order to design new, environmentally benign methods for control of wood decay fungi, it is esse...
