The use of preservative containing waste wood as substrate for growing greenhouse crops
1993 - IRG/WP 93-50011
In the Netherlands a large amount of waste wood and wood waste is produced every year. An important part of this amount comes from the pallet and packaging industries. One of the possibilities to re-use this relatively clean material is to convert it into substrates for growing crops in glass houses instead of the commonly used materials such as rock wool and glass wool. In this research, the infl...

Preliminary attempts towards the development of a small scale termite rearing chamber. Progress report
1983 - IRG/WP 1203
The results suggest that there is no evidence that the volume of the rearing chamber plays a part in the settlement of a colony. These rearing chambers present a factor of productivity (final enumeration)/(initial enumeration) of roughly 2 after one year. 90% of the colony survived. This method of breeding can be considered as feasible and cheap....

Iron in stone wool - one reason for the increased growth and decay capacity of Serpula lacrymans
1992 - IRG/WP 92-1537
The chemical compositions of stone wool and glass wool were analysed. There was more iron in the stone wool than in the glass wool. It was found that iron present in stone wool was easily dissolved by oxalic acid that Serpula lacrymans is able to produce. The stone wool promoted the decay of pine wood by Serpula lacrymans. The glass wool had no effect on the decay capacity of Serpula Iacrymans. Th...

Detection of Acoustic Emission (AE) generated by termite attack in a wooden house
1999 - IRG/WP 99-20166
Recently, considerable attention has been paid to methods for termite control, which involves few or no chemicals. To reduce the amount of termiticide needed, it is necessary to detect termite attack in wood as early as possible. The feasibility of acoustic emission (AE) monitoring for the nondestructive detection of termite attack has been discussed previously. In this study, we propose some tech...

The geographical distribution of the house longhorn beetle Hylotrupes bajulus (L) Serville (Col., Cerambycidae). An attempt at a cartographical compilation of existing data
1978 - IRG/WP 176
The larvae of the house longhorn beetle belong to the most economically important pests of softwood in service in most European countries and also in some areas overseas. I have reported earlier regarding the history, the question of where the pest originally came from, and concerning attacks in earlier and recent times (1968, 1970, 1974, 1976). In this report an attempt has been made to compile c...

Tanalith T - a new preservative system for protecting house frames in Australia from termite attack.
2003 - IRG/WP 03-30306
The sawn timber industry in Australia has expressed a desire for a new low cost termite treatment. The treatment needs to be on-line in the dry mill, minimising material handling costs and with a very fast processing time to meet timber flow through the dry mill. The preservative, Tanalith® T, forms an envelope on both Pinus radiata and Pinus elliotti sawn timber. Field trials conducted in Aus...

Threshold levels for dip treatments of chlorpyrifos for borer control
1995 - IRG/WP 95-10137
Chlorpyrifos has been used in non-pressure treatments of freshly sawn lumber and millwork for ten years or longer to control wood boring beetles. Since chlorpyrifos provides a quick kill of existing beetle larvae at the time of the treatment in solution concentrations as low as 0.05%, treaters tend to use less than recommended rates as a cost saving measure. However, laboratory studies conducted i...

Über Hausbock Hylotrupes bajulus (L.), (Col., Cerambycidae), in Laubholz: Versuche mit Laubholzarten, Prüfung der Wirkung von Ligninstoffen und von Ginkgo biloba, Beobachtungen an Hesperophanes. [On House-longhorn Beetle Hylotrupes bajulus (L.), (Col., Cerambycidae) in hardwood: Investigations with several hardwood-species, tests on activity of lignin components and Ginkgo biloba, observations on Hesperophanes]
1982 - IRG/WP 1144
Hylotrupes bajulus-larvae feed and develop in softwoods, hardwood acts as a feeding poison. The reason for this is still little known. According to literature some observations contradict this established opinion and the question was raised, whether the colour-strain scutifer (= lividus) is able to live in hardwood. Testing ten European and tropical hardwood-species (following the DIN-EN test proc...

Service life of outdoor wooden constructions. Expectations of private house owners in Sweden
2001 - IRG/WP 01-10401
Wood is traditionally used in indoor as well as outdoor applications. However, if not kept dry, wood is easily attacked by wood degrading micro-organisms. Thus the service life is heavily affected by construction design, choice of wood and wood treatment. For most constructions there is an expected service life. The expectations concerning wooden constructions and what kind of wood is chosen to fu...

Practical experiments with Boracol 10 Rh used as a fungicide in the repair process after attack by the dry rot fungus (Serpula lacrymans)
1987 - IRG/WP 3458
The test is carried out in an old house in Nyhavn, Copenhagen. The roof and the walls close to were heavily attacked by dry rot fungus (Serpula lacrymans) because damage to the zinc covering the frontspice were letting in water to the wood and wall construction. An attack by the dry rot fungus is more complicated to repair compared with other wood destroying fungi because beside the damage on wood...

In-house accelerated method for testing decay resistance of treated wood
2004 - IRG/WP 04-20286
Fungicidal compounds often change their effectiveness when they are incorporated into candidate formulations. For this reason fungistatic effectiveness needs to be re-evaluated as many times as the formula has been modified for better performance. To avoid multiple expenses, in-house fungistatic tests are essential. Our goal was to develop in-house usable, simple but reliable and reproductive proc...
