Survival of Bursaphelenchus xylophilus exposed to different active ingredients of wood protectors
2013 - IRG/WP 13-10802
The pine wilt nematode (PWN) Bursaphelenchus xylophilus (Steiner and Buhrer 1934) Nickle, 1970 is a quarantine organism with a high potential to damage Conifer forests in Europe. This has driven the European Union to protect forest stands from the propagation and dispersion of this pathogen.The nematode was first detected in Europe in Setubal (Portugal) in 1999 and eradication measures were taken....

Product efficacy against Fusarium circinatum, a quarantine organism in Europe
2013 - IRG/WP 13-10807
Fusarium circinatum Nirenberg et O'Donnell (telemorph: Gibberella circinata Nirenberg et O'Donnell) is a quarantine organism in Europe producing the disease known as pitch canker of pines. For a decade, the European Union has taken steps to locate and eradicate the pathogen with the aim of eliminating the risk of spread. So far, research has focused on forest stands, however, the movemen...

Efficacy of commercial wood preservatives against Bursaphelenchus xylophilus, a quarantine organism in Europe
2014 - IRG/WP 14-30638
Bursaphelenchus xylophilus (Steiner and Buhrer 1934) Nickle, 1970, pine wilt nematode (PWN), is a quarantine organism with a high potential to damage Conifer forests in Europe. This has driven the European Union to protect forest stands from the propagation and dispersion of this pathogen. Since the nematode was detected in Europe, eradication measures were taken. However, these measures were unsu...

Study of the effectiveness of wood products for permanent protection against Fusarium circinatum
2014 - IRG/WP 14-30655
In Europe there exist a number of quarantine organisms that affect conifer forests, including Fusarium circinatum Nirenberg et O'Donnell (telemorph: Gibberella circinata Nirenberg et O'Donnell), a quarantine organism in Europe producing the disease known as pitch canker of pines. For a decade, the European Union has taken steps to locate and eradicate the pathogen with the aim of elimina...

Wood protectors to control Bursaphelenchus xylophilus
2015 - IRG/WP 15-30661
Bursaphelenchus xylophilus, the pine wilt nematode (PWN), is a quarantine organism with a high potential to damage Conifer forests in Europe. The European Union is concerned in the protection of forest stands from the propagation and dispersion of this pathogen. In this line, the current control measures have been unsuccessful in preventing the dispersion of this organism, as it continues to be de...

Activity of wood preservatives against mould fungi
2016 - IRG/WP 16-30695
The resistance of experimental and commercial wood preservatives to mould fungi was determined using a method recommended by the Building Research Institute Instruction. The research of the inhibiting actions of the growth of fungi was carried out on the Scots pine wood Pinus sylvestris L. and beech Fagus sylvatica L. The most active compounds against mould were experimental herbicidal ionic li...

Exterior paint for the future - Will there be any dry-film preservatives left?
2017 - IRG/WP 17-50332
Wooden houses have a long tradition in several of the Nordic countries. Wood can be protected in various ways; constructional, chemically and by surface treatment. The use of various types of exterior paints as a surface treatment is a common way to prolong the durability of the wood. To further protect the painted surface against growth of fungi and algae, dry-film biocides remains an essential p...

Response of the symbiotic flagellate protists community of subterranean termites to sublethal amounts of biocides
2018 - IRG/WP 18-10911
Subterranean termites are quite efficient at extracting nutrients from lignocellulose. Their ability relies not only on the digestive tract physiology but also on symbiotic relationships established with flagellate protists and bacteria. This work aimed to screen the response of the flagellate protists community of the subterranean termite Reticulitermes grassei Clément to the ingestion of differ...

Rapid Screening test of potential antimicrobial agents for wood coatings
2018 - RG/WP 18-20644
A two-part screening test has been developed to evaluate additives for wood coatings. First, an additive is tested in the microbial laboratory and evaluated based on its inhibitory properties against selected test organisms, directly on agar plates. A microbial growth analysis is prepared and evaluated. If the additive is considered effective, it will be tested in a standard top coating (acrylic o...

Influence of different triazoles as co-biocides in wood preservatives on efficacy and the environmental impact
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...

Monitoring of wood preservatives exposed to weathering: Extraction and analysis methods of organic biocides from treated wood and collected rain runoff
2020 - IRG/WP 20-30753
Weathering is the cause of numerous damages for outdoor joineries. Protection of wood using a preservative treatment covered with a coating is a process widely used to limit these damages. However, biocides from preservative treated wood are prone to degradation and leaching, having a direct influence on the joinery service life. This document deals with extraction and analytical methods for bioci...

An Update on the Status of Industrial Heavy-Duty Preservatives in Europe
2022 - IRG/WP 22-30762
Creosote has been used for over 150 years for preservation of heavy duty industrial timbers such as railway sleepers, utility poles, and agricultural posts. The regulatory regimes in place today across Europe (eg EU & GB Biocidal Products Regulation (BPR)) require a detailed assessment of the environmental and human health properties of wood preservatives at both the active substance and product l...
