Soil blocks versus field test for evaluating and standardizing wood preservatives: A commercial view
1994 - IRG/WP 94-20024
On the basis of technical considerations, experience, costs and applicability, the author concludes that the soil block test and other laboratory tests have little meaning in a wood preservative standardization process and almost no merit in the commercialization of a wood preservative system. Field tests at sites known to be aggressive to preservative treated wood are strongly recommended....

AAC preservatives: Recent New Zealand and Australian experience
1982 - IRG/WP 3188
This paper outlines the present commercial situation in New Zealand, presents results of current research undertaken at FRI and CSIRO, Division of Building Research (DBR), and comments on parallel research carried out elsewhere. Finally, some general comments are made on the limitations of present technology....

A survey to assess the current and future usage of timber in British port structures
1998 - IRG/WP 98-10247
Port engineers responsible for 30 British ports were surveyed by questionnaire or interview to establish current and prospective usage of timber in those ports. The ports surveyed account for about 25% of total cargo handled annually in Britain and being located all around the British mainland, were considered to form a representative sample. The survey identified the hardwoods and softwoods in us...

Targeting fungal proteinases to prevent sapstain on wood
1995 - IRG/WP 95-10097
Discoloration of wood, caused by a variety of sapstaining fungi, leads to periodic losses in the Canadian lumber export industry. Proteolytic enzymes are thought to be necessary for retrieval of nitrogen during fungal growth on wood. The major extracellular proteinase of Ophiostoma piceae, a representative sapstaining fungus, was purified to homogeneity and its inhibition pattern characterised. Cl...

The effectiveness test of chemicals against Serpula lacrymans
1984 - IRG/WP 2222
The effectiveness tests of wood preservatives against Serpula lacrymans were conducted in accordance with Japan Industrial Standard A 9302 and Japanese Wood Preserving Association Standard No. 1. Also, the soil treatment test against this fungus was carried out with two chemicals. The preservatives tested without Creosote oil (out of JIS) had sufficient preservative effect against Serpula lacryman...

Treatment behaviour of fresh and inservice catamaran logs
2001 - IRG/WP 01-30255
Catamaran is a conventional fishing craft fabricated by lashing 4 - 6 shaped logs of soft timber together. Over 73,000 of these craft fabricated out of 165,000 m3 of wood are in use along the vast east coast of India. Each craft lasts for 5-7 years. Over 15,000 m3 of timber is required annually for repairs and replacements of the craft. Such huge demand exerts enormous pressure on the resources. I...

Accelerated fixation of CCA in borak bamboo (Bambusa balcooa Roxb.) of Bangladesh
2001 - IRG/WP 01-40193
CCA-C fixation study on impregnated (6% CCA solution), then boiled, oven-dried, normal, air-dried and steamed bamboo slices of air-dried borak bamboo (Bambusa balocca Roxb) of Bangladesh, revealed almost complete fixation in steamed (accelerated fixation) and air-dried (3 weeks, slow fixation) bamboo slices compared to moderate to slow fixation in boiled, oven-dried, normal and 24h air-dried slice...

Preliminary results of investigations on screening test of chemical compounds suitable for the preservation of lignocellulosic materials against biodeterioration
1976 - IRG/WP 262
This paper investigates the possibilities of reducing the time needed for the determination of the effectiveness of chemical compounds from the point of view of their eventual application to lignocellulosic materials for preservation against decay and soft-rot....

Utility, deterioration and preservation of marine timbers in India
2005 - IRG/WP 05-40314
Timber is extensively used in India in the marine environment for various purposes due to its several advantages over modern materials. Infact, its use is increasing in recent years, finding wider and wider applications and this scenario is not going to change in the near future. Though, the bio-deterioration problem is found very severe in tropical waters, still indigenous methods are widely empl...

The 1999-2000 annual report for the IRG - Wood Preservation in Egypt
2000 - IRG/WP 00-40188
The wood destroying insects in Egypt are belonging to several families of Coleoptera, Lepidoptera and Isoptera. Imported woods are treated by The Agricultural Quarantine or the authorized companies. The materials used for protection as pre-treatment are the same of the treatment. They are Bromide methyl, copper or fluoride salts, organo-phosphorus compounds, pyrethroides, creosote or creosodial. A...

Biological control of Serpula lacrymans using Trichoderma spp
1994 - IRG/WP 94-10069
The effectiveness, or otherwise, in killing Serpula lacrymans, of a range of Trichoderma spp. in a variety of media and using two different incubation systems has been tested. In agar based systems with normal nutrients or minimal nutrients with high or low nitrogen contents and high or low iron content Trichoderma harzianum 25 proved to be the most efficient and killing Serpula lacrymans. Other s...

Collaborative soft rot tests
1981 - IRG/WP 2151
There appears to be need for reconsideration of attitudes towards Standardisation of laboratory tests for determining the toxicity of preservatives to soft rot fungi. The original approach was that a limited number of test methods were available and that collaborative effort would determine the suitability of the methods for Standardisation. It has been established so far that pure culture testing...

Some physiological characteristics of a non-degradative strain of Postia (=Poria) placenta
1988 - IRG/WP 1341
The decay capacity of 14 strains of the brown-rot fungus Postia (= Poria) placenta was determined using soil-wood block tests. One isolate was identified as being unable to degrade wood and was determined to be monokaryotic. It retained the ability to produce extracellular carbohydrate-degrading enzymes, although regulation of certain enzymes was atypical under certain cultural conditions. It prod...
