Encapsulated Active Ingredients for Wood Preservation
2017 - IRG/WP 17-30717
Encapsulated organic fungicides and termiticides have been examined for use as wood preservatives in vacuum pressure treatment of wood. Encapsulation of active ingredients was found to improve wood penetration behaviour and reduces leaching as well as biodegradation of the active ingredients compared to industrial standard formulations....

Utilization of plasma treatments in the field of wood protection
2021 - IRG/WP 21-40912
Plasma treatments have been used for modification of surfaces of wood and wood-based materials for some decades and solutions were developed to apply it for wood protection. This contribution aims to present the background, introduce the available plasma technology, and to give an overview on the typical applications and benefits....

Generic code of good practices for wood protection facilities. Part 1: Wood protection (antisapstain) facilities
1993 - IRG/WP 93-50003
In general, the potential of high toxicity (aquatic and human) of wood protection (antisapstain) chemicals dictates the need to protect the environment and humans from its harmful effects. This document is a compendium of recommendations for the design and operating practices of wood protection facilities. The suggested recommendations focus on achieving the objectives of protecting the environmen...

Laboratory evaluation of fipronil (a phenyl pyrazole) as a candidate termiticide in the protection of wood against the subterranean termite, Coptotermes acinaciformis (Froggatt) Rhinotermitidae
1997 - IRG/WP 97-10225
In this laboratory evaluation, radiata pine wood blocks (50 x 25 x 15 mm3) were impregnated with fipronil (a phenyl pyrazole) at various concentrations (0, 5, 10, 20, 40, 80, 100 and 200 ppm). Half the treated blocks underwent a leaching schedule for 5 days, while the remainder were unleached after treatment. Five replicates per treatment regime were presented to the test termite, Coptotermes acin...

Practicability of bioassays in the evaluation of environmental risks in wood protection
1996 - IRG/WP 96-50071
As an example for the proofing of the practicability of bioassays in the evaluation of environmental risks in wood protection the ecotoxicological behaviour of CCF-impregnated timber was examined. After vacuum pressure impregnation specimen from shaped pine poles were tested on ecotoxicological effects of leachable compounds using sensitive aquatic organisms like fish, Daphnia and algae as bioindi...

Durability of surface preserved wood particle boards submitted to atmospherical influence
1995 - IRG/WP 95-40039
The worldwide problem of the continuously growing deficit of high quality natural wood material has caused the attempts of many research workers to find effective composites such as wood particle boards (WPBs) for replacing the massive wood for constructive purposes, depending on where the boards are exploited - in the open or under a shed, they are submitted to various climatic factors such as he...

Determination of fixation properties by bioassays - A proposal for the assessment of safety indexes in wood protection
1990 - IRG/WP 3566
In the determination of environmental effects of chemicals tests with fishes, daphnia and algae have proved to be practicable. With respect to wood protection such bioassays are suitable to control effects of treated timber against aquatic organisms. By using the fish-acute-toxicity-test the development of a laboratory test method is described for the checking of the fixation rate of a copper-chro...

Efficacy of linear chain carboxylic acid anhydrides as wood protection chemicals
2002 - IRG/WP 02-30295
This paper presents an assessment of the effectiveness of linear chain carboxylic acid anhydrides namely, acetic, propionic, butyric, valeric and hexanoic anhydride, in improving the decay resistance of Corsican pine (Pinus nigra Schneid) sapwood. Wood-anhydride bond formation was verified by the increase in sample weight and volume. A brown rot fungus [Coniophora puteana (Schum.:Fr)] was selec...

Wood protection processes in the Asean countries
1994 - IRG/WP 94-40034
This paper presents the wood processing practices in the Asean countries composing Indonesia, Malaysia, Philippines, Singapore, and Thailand except Brunei. The development of wood preservation industry in these countries started as early as 1922 to 1960. As in other industrial countries, treatment pressure with creosote of utility poles, railway sleepers, and marine pilings are the prime commoditi...

Assessment of the toxicity of some copper-, zinc- and boron-based wood preservatives to the cellar fungus Coniophora cerebella Schröet
1974 - IRG/WP 242
This article reports the use of a method based on the determination of the probability of the protection of timber against destruction by fungi. By converting the probability values to probit values and plotting them as a function of the amount of preservative retained in the timber, curves of the toxic effect are obtained, enabling any timber protection probability to be assessed....

Wood protection by surface treatment of two borate preservatives, TIM-BOR® and BORA-CARE®, for the formosan subterranean termite and eastern subterrean termite
1993 - IRG/WP 93-10044
TIM-BOR® (disodium octaborate tetrahydrate: DOT, Na2B8O134H2O) and BORA-CARE® (40% DOT in ethylene glycol) are two borate products marketed for treating wood in use by brushing or spraying onto the wood surface. The active ingredients presumably diffuse into wood by the 10-15% existing wood moisture. Few data, however, are available to demonstrate the diffusion rate. Su & Scheffrahn (1991) s...
