Efficacy of Xotic Wood Preservative to control termites attack on Pinus patula wood
2018 - IRG/WP 18-10915
This study aimed at evaluating the efficacy of Xotic Wood Preservative on treated wood. Solignum was the experimental standard. The experiment was laid out in a Randomised Block Design carried out as a graveyard trial with 15 samples, 3 treatments and 5 replicates. The results showed that there was significant difference (P<0.05) in weight of the wood after four months of the graveyard trial. Term...

Chemical composition and termiticidal activity of Khaya ivorensis stem bark extracts on woods
2018 - IRG/WP 18-30723
The genus Khaya is extractives rich, but the extractives in the stem bark are among the most abundant, accessible and utilised materials in Nigeria. These extractives are of considerable interest for wood protection because of their pesticidal properties. In this study, the chemical constituents of Khaya ivorensis stem bark (KISB) and their termiticidal activity were investigated on Triplochiton s...

Preventivephysical barriers against subterranean termites species for building protection: How to implement innovative materials to reach efficacy requirements
2018 - IRG/WP 18-40845
As the European regulation dealing with the use of biocides (BPR) for preventive protection of buildings against subterranean termites is leading to more and more pressure on physico-chemical barriers currently used (PT18), some existing developments are focusing attention on physical biocides-free barriers. The main target is then to avoid the use of active ingredients, to stay out of the BPR sco...

2018 - IRG/WP 18-50333
In this study we investigated the efficacy and impact on the environment of different co-biocide triazoles in wood preservatives. Four different formulations (all containing 9.5% Copper) contained individual and combinations of cyproconazole, tebuconazole, propiconazole as co-biocides. Four formulations were tested according to EN 113 and EN 84 (ageing) to determine the brv for each formulation. T...

Efficacy of microwave treatments against Pine Wood Nematode
2019 - IRG/WP 19-20658
The pine wood nematode Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle (PWN) is the causal agent of “Pine wilt disease” affecting coniferous forests, and since its detection in 1999 in Portugal, has obliged the European Union to take action to prevent its spread (Decision 2006/133/CE). One of the main measures applied is the International Standard for Phytosanitary Measures ISPM No. 15 ...

Application of nano metal fluorides against termites
2019 - IRG/WP 19-30733
Recent research has shown that fluorides such as NaF have potential as a wood preservative against termite attack (Pan and Wang, 2015). However, NaF has high leaching susceptibility because of its solubility (40 g/l ) which can reduce its efficacy over long term. Metal fluoride nanoparticles such as MgF2 and CaF2 present a viable alternative to water soluble fluoride-based wood preservatives as th...

Relative efficacy of various oxine copper formulations against brown-rot fungi
2019 - IRG/WP 19-30741
This paper investigates the relative resistance of three different oxine copper formulations (oil-borne, water-borne, water-borne with pH-adjustment) as a preservative treatment for wood against brown-rot fungi. Impregnated southern pine sapwood cubes were exposed to R. placenta and G. trabeum cultures in a soil-block test. After eight weeks, the weight losses of the cubes were examined in relatio...

Chemical Analysis of Southern Pine Pole Stubs Sixty Months Following Treatment with a Methylisothiocyanate-Based Solid Fumigant Stick
2019 - IRG/WP 19-30740
Methylisothiocyanate-based fumigants have been commercially used in the United States for over 35 years to control internal decay in utility poles and other wooden structures with little technological advancement. The most recently commercialized methylisothiocyanate-based fumigant is chemically known as dazomet. Dazomet is a free-flowing powder or granule that decomposes in the presence of mois...

Studies on the material resistance and moisture dynamics of Douglas fir and Sitka spruce from Slovenia
2021 - IRG/WP 21-20677
Wood in outdoor applications is subject to various decomposition factors. Wood degradation can be prevented by construction details, biocide protection of wood, wood modification, or selection of naturally durable wood species. Unfortunately, the majority of timber species in Europe do not have naturally durable wood. Imported tree species represent a new pool from which we can draw wood species w...

Comparative study on the efficacy of biobased wood preservative over conventional wood preservatives against fungi and termites
2022 - IRG/WP 22-30761
The current focus of wood preservation research is on developing wood preservatives from natural and environmentally compatible compounds for industrial application. Liquefaction of wood is one of the promising approaches to utilize woody waste where the wood powder is converted into a chemically active liquid with the help of a liquefying agent like phenol, cresol, plant-based solvent as CNSL and...

A novel method for assessing radial variation in termite resistance of timber
2023 - IRG/WP 23-11005
Australia has many timbers whose heartwood is highly resistant to fungal and termite attack; however, changing public policies have resulted in restricted access to many native forests where these species are found. Plantations of these same species are expected to replace these resources, but there are questions concerning whether timber from these trees will have the same resistance as the nati...

Evaluation of the efficacy of silver nanoparticles and chitosan oligomer composites as poplar wood protective treatments against termites
2023 - IRG/WP 23-40963
Populus × euramericana ‘I-214’ (poplar) is a fast-growing species widely distributed throughout the world, and in the Castile-Leon region of Spain it accounts for more than 50% of all plantations. Its wood is becoming increasingly appreciated, yet its low durability against xylophagous agents —termites being one of the most aggressive and destructive in warm climates— continues to be a li...

Longitudinal tensile shear properties of polyurethane-bonded preservative-impregnated Eucalyptus grandis laminates subjected to varied simulated climatic conditions
2023 - IRG/WP 23-40967
Bonding process adaptations have yielded improvements in the adhesive bonding of Eucalyptus grandis wood for manufacturing hardwood laminates. However, there are still concerns over the adhesive-bond performance, particularly preservative-impregnated E. grandis laminates, under exposure to varying climatic conditions. These concerns could limit the implementation of E. grandis laminates, especiall...

What products are architects using? Relationships between deterioration part and structural performance in wooden houses
2023 - IRG/WP 23-50374
Architects work in the development of ideas around buildings and all the nuclei where human activity is generated. It is a work of organization of matter, in time and space, where the conceptual world of ideas and the aspirations of inventions, the interior world interact with the exterior in many kinds of realities.
But as architects, we have always been interested in why and how things have bee...

Relationships between deterioration part and structural performance in wooden houses
2023 - IRG/WP 23-50376
Based on the survey examples, there are four patterns of deterioration that tend to occur in plywood bearing walls of wooden houses in Japan. The first is a pattern in which wall is in a whole deterioration. It is a no damage wall or test specimen. The second is a pattern in which only the sill is deteriorating. It is caused by moisture or termites from ground to the base. In addition, there is a ...

Laboratory evaluation of PA1b, an insecticidal protein extracted from pea seeds (Pisum sativum), as bait active ingredient against the subterranean termite Coptotermes gestroi (Blattodea: Rhinotermitidae) in tropical zones
2024 - IRG/WP 24-11038
Coptotermes gestroi (Wassman 1896) is one of the worst pests in tropic areas, economically. Two types of curative methods are used since decades to eliminate colonies that attack constructions: injection of biocidal treatment solutions on wood, walls and soil, and population control using baits. In application of the current regulations, the first technique can no longer be used in Europe, to lim...
