Performance of Two Imidacloprid-Treated Malaysian Hardwoods in an Accelerated Aboveground Termite Test
2005 - IRG/WP 05-30389
The performance of the chloronicotinyl insecticide imidacloprid as a wood protecting termiticide, under a simulated Malaysian biological hazard class H2 (exposure aboveground indoors against termites and wood borers), was evaluated by a novel termite field test protocol. Replicate end-grain sealed air dried test blocks (20 x 20 x 20 mm) of two Malaysian hardwoods, Kembang Semangkok (Scaphium spp.)...

Analysis of tebuconazole in wood treated with Tanalith™ E
1999 - IRG/WP 99-20158
A simple gas chromatographic method for determining tebuconazole in Tanalith™ E treated wood is described. A two step sequential extraction procedure with methanol was used. Sample extracts were analysed without cleanup or concentration using capillary column GC with thermionic specific detection. The performance of the method was assessed using radiata pine (Pinus radiata) sapwood, radiata pine...

Some data on the activity of alternative fungicides for wood preservation
1985 - IRG/WP 3333
Data from laboratory tests against basidiomycete fungi are presented for 9 alternative fungicides in organic solvent formulations and also in water for one product. Results are compared with data for reference preservatives, tributyltin oxide, copper and zinc naphthenates and pentachlorophenol. Of special interest is the apparently better than additive effect of mixing tributyltin naphthenate and ...

Microbial tolerance and biodetoxification of organic and organometallic biocides
1990 - IRG/WP 1464
Ten organic and organometallic biocides were assessed for toxicity towards a range of wood decay and spoilage fungi. Minimum inhibitory concentrations indicated selective toxicity of biocides towards particular fungal types. Certain species of fungi demonstrated tolerance to a range of biocides. Further tests using the biocides in soil and wood enrichment cultures resulted in isolation of highly t...

A field test with anti-stain chemicals on sawn pine timber in Brazil
1989 - IRG/WP 3513
Field tests were carried out in São Paulo State - Brazil, to evaluate pre-treatment formulations of O-Phenyl-Phenol (OPP) based products. The Sodium Pentachlorophenate solution was used as a reference formulation. The treated test blocks were stacked in a covered shed, and in an uncovered place for air drying. The evaluation was done by measuring the percentage of stained surface on each test blo...

Artificial weathering as an aid to assessing the effectiveness of chemicals for preventing blue stain in service - a co-operative study
1984 - IRG/WP 2215
The paper reports co-operative studies carried out within Working Group II of the International Research Group on Wood Preservation to assess the effects of different artificial weathering systems on the performance of fungicides to control blue-stain in service. It has been shown that Atlas, Xenotest and Marr equipments operated according to particular standard schedules can give essentially the ...

Blue stain in timber in service. Preliminary results of the IRG collaborative tests to compare natural and artificial weathering
1978 - IRG/WP 286
The collaborative programme was initiated at IRG Meetings in Wildhaus, 1976. The six collaborators were BAM (Berlin), Cuprinol Ltd (UK), EMPA (Switzerland), GORI (Denmark), PRL (UK) and Imperial College (UK). Experimental plans were finalised in December 1976 and panels treated by Cuprinol Ltd early in 1977. Natural weathering was carried out by BAM, Cuprinol, EMPA, GORI and PRL during April-Septe...

Blue stain in timber in service. Progress review of Sub-group collaborative tests - 1981/82
1982 - IRG/WP 2178
Following from the discussions after reporting Document IRG/WP/2146 at the Meeting in Sarajevo, 1981, it was decided that 1.) more precise definition was needed of the artificial weathering schedules used in the work - participants to re-check Table 8 and send further details or amendments to Dr Bravery; 2.) a further test employing a wider range of chemicals was necessary using a smaller range of...

Response of Terminalia mantaly H. Perrier wood to beetles tunneling in Southern Nigeria
2018 - IRG/WP 18-10918
Terminalia mantaly (TM), is extremely susceptible to beetles attack, as evidenced by the many scars and/or tunnels on nearly all the trees in the Southern Nigeria. However, information on the responses of wood to insects tunnelling is poorly known for tropical species. To examine the response of TM stem wood to beetles tunnelling in the University of Port Harcourt, we scheduled field observational...
