The compatability of tributyltin fungicides and synthetic pyrethroid insecticides as wood preservatives
1987 - IRG/WP 3414
The stability of three synthetic pyrethroids, cypermethrin, deltamethrin and permethrin, to selected tributyltin compounds, Bu3SnX {where X = OSnBu3, Cl, 02CC6H5, O2C (Naphthenyl), OSO2Et}, (Bu3SnO)3PO and {NBu4} {Bu3SnCl2}, in toluene solution was investigated by infra-red spectroscopy over a six month period. It was found that only (Bu3Sn)2O reacted with the pyrethroids and that their order of r...

FLUROX, a new breakthrough in insect control for wood preservation
1995 - IRG/WP 95-30079
FLUROX (flufenoxuron) is an acylurea insecticide which acts as a growth regulator in insects. FLUROX inhibits the production of chitin - the exoskeleton or 'skin' of the insect. When the exposed larva attempt to moult to its next stage of development, it is unable to produce a new skin and dies. FLUROX has been found to be extremely active against wood borers, when applied in a p...

Compatibility of deltamethrin with wood-finishing and construction materials
1993 - IRG/WP 93-30010
Under normal use conditions, treated wood comes to close contact with the structural components of a buiLding, and/or receives finishing, forming a new interface, which can affect the performance of a new product such as deltamethrin. To study this possibility, block-tests of Parana-Pine (Araucaria angustifolia), measuring 12 x 24 x 0.5 cm³ (with the largest dimension parallel to the wood-grain),...

Compatibility of deltamethrin with wood adhesives
1993 - IRG/WP 93-30031
This work presents the studies conducted on the compatibility of deltamethrin when mixed with wood adhesive to manufacture plywood in order to protect the wood against wood-borers insects and termites. The following types of adhesive were tested: PVA, Urea-formaldehyde, phenol-formaldehyde and a formulation based on tannin. The experiments were made in the adhesive manufacturers' laborato...

FAROX, a novel insect growth regulator for use against wood-boring insects
1995 - IRG/WP 95-30080
The active ingredient in FAROX - fenoxycarb - is a novel insect growth regulator for preventive use against wood-boring insects (Hylotrupes, Anobium and Lyctus). FAROX has the same biological effect as a natural insect growth factor produced by the insect itself. FAROX is tailor-made for insect control; it attacks at the points where the insect should normally be changing its form and blocks these...

Wood cement composites using spent CCA treated wood
1999 - IRG/WP 99-50126
The feasibility of using spent or out-of-service CCA treated wood as a component of wood/cement composites was evaluated. Cold pressed wood particle cement boards were made using CCA treated particles from a red pine (Pinus resinosa Ait.) pole removed from service and from untreated red pine wood from a new pole. Boards were manufactured using a range of wood to cement ratios and water to cement r...

Compatibility of Acetylated Wood and Wet Concrete
2014 - IRG/WP 14-40673
One of the newer commercial technologies to provide stability and durability to wood and wood composites is the process of acetylation (the reaction of acetic anhydride with wood). Wood is often used in contact with concrete, although only a very limited amount of species are suitable for this type of application because of durability issues. From this perspective durability class 1 timber such ...

DuraSoft Project: a multidisciplinary approach for softwood protection
2021 - IRG/WP 21-50367
Over the course of millennia, fishing and agro-pastoral activities have produced unique housing types in the Italian lagoons and in the Slovenian highlands where the use of wood is predominant. They are associated with wooden service infrastructures such as piers, moorings, piling and fences. However, the existence of these structures and the associated cultural heritage are subject to constant ...

Evaluation of ecotoxicological effects of different coniferous wood treatments on two marine bioindicator species
2022 - IRG/WP 22-10999
Coniferous wood panels (Picea abies) were treated with two concentrations of copper-based impregnating agent to increase its durability in marine and brackish environment. In order to assess the environmental compatibility of the treatments a laboratory experiment was conducted with two marine invertebrate species: bivalve Mytilus galloprovincialis and a gastropod Steromphala albida. The bioindica...
