Improved PEC preservatives with added biocides
1985 - IRG/WP 3322
Biocidal chemicals have been incorporated into formulations within the broad framework of pigment emulsified creosote (PEC) to provide novel potential multi-purpose preservatives. Preparations of PEC plus TCMTB, Boracol 40, copper ethanolamine nonanoate, Quatramine 80, arsenic trioxide, Troysan Polyphase, and CCA have been formulated and assessed for preserving ability in soil-jar and Accelerated ...

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...

Testing of termiticides in soil by a new laboratory method with regard to Phoxim for replacement of chlorinated hydrocarbons
1986 - IRG/WP 1292
In comparison to chlorinated hydrocarbons insecticides of the compound classes organophosphates, carbamates and pyrethroids were tested according to an earlier described soil-test in the laboratory. The following termite-species were used: Heterotermes indicola, Reticulitermes santonensis and in addition Reticulitermes flavipes, Reticulitermes lucifugus, Reticulitermes speratus and Coptotermes for...

Observations on the failure of anti-sapstain treated timber under non-drying conditions
1990 - IRG/WP 1437
A range of bacteria and yeasts were isolated from antisapstain treated timber and fresh sawdust. Solution samples containing 100 ppm of TCMTB in a nutrient medium were inoculated with these organisms and incubated at 25°C for 5 days. The levels of TCMTB remaining in solution were determined by HPLC analysis after this time. Results indicated high losses of active ingredient for a range of organis...

Movement of boron from fused boron rods implanted in Southern pine, Douglas fir, red oak, and white oak timbers
1995 - IRG/WP 95-30061
This paper reports the distribution of boron from fused boron rods installed into six-inch (15.2 cm) square timbers of Douglas-fir, Southern Pine, red oak and white oak exposed aboveground. The composition and size of rods was: sodium borate and sodium borate-copper oxide (8.5 x 100 mm²); sodium borate-copper, sodium borate and boric oxide-copper oxide (12 x 76 mm²). The boric acid equivalent wa...

Above ground performance of CCA-treated fingerjointed lumbe
1993 - IRG/WP 93-40003
Studs made from short lengths by finger jointing are becoming more commonly used in North America. Recently Forintek has received enquiries about the performance of such material in a treated form. Treated and untreated nominal 2x4 inch² spruce-pine-fir (SPF) studs exposed above ground for 12 years in southwestern British Columbia were evaluated for evidence of decay. Despite shallow preservative...

Information from the COIPM Wood Group. Summary received via Mme Dr Anna Gambetta (Italy)
1987 - IRG/WP 4139
Two co-operative programmes were discussed: 1) The IRG/COIPM co-operative programme on the CCA/CCB wood treatments and 2) The IRG/COIPM co-operative programme for testing the resistance of plastic wrapping for wooden pilings. The following was reported: In the wood treatment programme, beech, pine and alstonia wood samples have been pressure treated with 3 retentions (3%, 6% and 10%) of CCA and CC...

Iron promotes decay capacity of Serpula lacrymans
1993 - IRG/WP 93-10008
The influence of iron and iron compounds on the decay capacity of Serpula lacrymans was studied. Mass losses of pine wood caused by dry rot fungus were increased when FeSO4 was added into the culture medium or when there were iron nails or stone wool on the culture medium. This supports the hypothesis that iron in stone-based building materials is one reason for the increased decay capacity of Ser...
