Laboratory evaluation of chlorothalonil against the Formosan subterannean termite
1992 - IRG/WP 92-1559
The fungicide chlorothalonil was evaluated as a wood preservative to prevent attack by the Formosan subterranean termite, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae). Southern yellow pine wafers treated with chlorothalonil (CTL) in P9 oil, CTL + chlorpyrifos in P9 oil, or CTL in xylene were conditioned by evaporative aging at 40° C for 4 weeks and exposed to termite attack in a mod...

The effect of composition on the effectiveness and fixation of CCA and copper/chrome preservatives. Part 1: Effectiveness. Part 2: Selective absorption and fixation
1973 - IRG/WP 324
A preliminary study of a wide range of copper-chrome-arsenic formulations indicates that the most effective are in the region, CuSO4 · 5H2O - 35 to 45 per cent; K2Cr2O7 - 40 per cent and above; As2O5 · 2H2O - 25 to 15 per cent or less. Effectiveness appears to depend more on the copper content than the copper - arsenic. Observations on selective absorption and leaching suggest that the chromium ...

Comparison between two laboratory test methods for determining the effectiveness on wood preservatives against blue stain in fresh wood
1987 - IRG/WP 2289
Most of the work done on determination of the effectiveness of new formulae for treating fresh wood against blue stain have been focussed on their use in the manufacture of saw timber. This work explains two laboratory methods, one which simulates the working and climatological conditions of factories making packages for fruit and vegetables in the Spanish Levante, showing that contamination of wo...

1992 - IRG/WP 92-3705
A modified soil block test was carried out using wood samples reacted with heptadecenylsuccinic anhydride (ASA). This modification gave good resistance to decay brought about by the brown rot fungi Coniophora puteana and Gloeophyllum trabeum during the twelve week exposure period. Results indicated that there was a good correlation between increased loading of modifying reagent and an increase in ...

Water-based silicones on wood
1997 - IRG/WP 97-30144
Five waterbased silicones commonly used on masonry where tested as water repellents for wood. The Water Repellent Effectiveness was determined by swellometer-tests and by measuring the water uptake of samples after 24 hours complete immersion and by immersion in a water level of 4 mm for 24 hours. The different methods are compared and discussed. Artificial and natural weathering was performed to ...

The effectiveness of three tributyltin compounds in beech against soft rot fungi using a soil-bed technique: A preliminary report
1986 - IRG/WP 3390
The effectiveness, towards soft rot fungi, of bis (tributyltin) oxide, tributyltin ethanesulphonate (TBTES) and benzyltributylammonium tributyldichlorostannate in both leached and unleached beech stakes is compared to that of a CCA preservative (Tanalith CT 106), using a soilbed technique. In addition, the effect of test solvent (water or toluene) on the performance of TBTES is evaluated. Total ti...

Sulfluramid, a new bait concept for the control of termites
1995 - IRG/WP 95-30075
The annual cost of preventing, controlling and repairing the damage done by termites in the United States of America is in the billions of dollars. Current termite control methodology is generally effective in the control of termite activity. However, new technology (termite foams, termite baits, physical barriers) is emerging which has or will provide new tools to control termites. This report ce...

The evaluation of the effectiveness of wood preservatives by means of IUFRO's method for field tests with wooden stakes
1985 - IRG/WP 3348
Pinus elliottii and Eucalyptus saligna stakes treated with CCA-A, CCA-C, CCB, Cashew Nut Shell Oil and Benzotar solutions were exposed in seven test sites in Sao Paulo State, Brazil. After five years of exposure, between oil-borne preservatives Benzotar show better performance than CNSL (cashew nut shell liquid), and within waterborne preservatives the performance of CCB is not so good as that of ...

Assessing the importance of degradation mechanisms on the loss of effectiveness of wood preservatives
2000 - IRG/WP 00-20193
Accelerated ageing systems developed for application to samples in the laboratory prior to biological tests, should reflect those natural deterioration processes that are likely to occur in the hazard classes defined in EN 335-1. Losses through evaporation or the effects of leaching have been recognised, however their importance, relative to other mechanisms has not been quantified. Degradation me...

Accelerated termicidal performance data for new water-based copper linoleate formulations
1996 - IRG/WP 96-30104
An organic solvent based copper linoleate (Culin) has proved itself as an effective wood preservative in long term field trials in South Africa over a period of 30 years. Whilst the organic solvent based product offers good wood preservative performance, primary industrial interest has been in an emulsified version of the product. The objective of this study was to evaluate the influence of two di...

Proposal for a simple methodology for the evaluation of the preventive effectiveness of protectors applied in superficial treatments against basidiomycetes fungi
1999 - IRG/WP 99-20167
Due to the considerable effect that the relation between the lateral surface and the volume of wood blocks has on superficial treatments, this work has attempted to determine the ideal size which allows to evaluate the effectiveness of a preservative in the shortest possible time. Three wood blocks of different dimensions were tested. In addition, as it is necessary to neutralise the effect of the...
