Wood preservation in Poland
2004 - IRG/WP 04-30362
Dynamic growth of market demand for wooden elements and articles, generated in Poland increase of interest in industrial preservation. Today, Poland is a substantial producer and exporter of wood made products. Majority of exported wood - approximately 70% - is scotch pine (Pinus silvestris L.), which, due to its natural durability, requires preservation....

Airborne algae as a wood degradation factor
1992 - IRG/WP 92-1549
The occurrence of airborne (aerophytic) algae on wood is a very frequent phenomenon. However, there is currently a lack of information concerning their effect on the wood tissue. Some important genus of algae infesting wood under natural conditions are listed, as well as the results of experimental studies in the "in vitro" culture concerning the effect of two selected algal species on some physic...

New developments in wood preservation
1974 - IRG/WP 335
Most of the developments in wood preservation in recent years have been stimulated by changing circumstances, particularly the increasing interest in reducing hazards and environmental, pollution but also the serious difficulties that are now being encountered in obtaining economic supplies of established preservatives. There is perhaps a danger that new controls to reduce pollution dangers may be...

The more important wood-destroying insects found in buildings in Poland
1974 - IRG/WP 128
In the different regions (voievodships) of the country Anobium punctatum and Anobium pertinax were to be found in the range of 47.7 to 63.5%. These insects were the main pests in urban buildings. In the second place came Hylotrupes bajulus occurring in the range of 25.9 to 45.1%. The other insects were to be found within the limits of 0.1 to 10.0%; only in a single instance did the amount reach 24...

Three years of field tests with "Lignomer" stakes in ground contact
1981 - IRG/WP 3166
The "Lignomer" (Wood Polymer Composite) is a material obtained during the polymerisation of various monomers or its mixtures in wood. As laboratory tests have shown, this material is characterized by a high resistance against biological deteriorating agents. The laboratory investigations on the durability of various materials against biological deterioration are in many instances extended by field...

Protection of freshly felled timber against attack by bark boring insects
1981 - IRG/WP 1143
This report describes two experiments with the insecticide formulation Perigen, which contains the synthetic pyrethroid permethrin. At 0.2% w/v active ingredient individual logs were protected against bark boring beetles for 18 weeks. At 0.3% w/v active ingredients Perigen gave similar protection against insect attack to stacks of recently felled unbarked pine logs. This protection was at least eq...

Information on a project about the conditions of admissibility of wood-protecting agents in connection with environmental protection in Poland
1974 - IRG/WP 57
Wood-protecting agents are compounds acting toxically on fungi and insects. If handled improperly or carelessly, they may exert an action harmful to health and safety of men. This action is concerning: a) workers employed at the production of wood-protecting agents; b) workers employed at the impregnation, or at the transport and handling of impregnated wood; c) inhabitants of buildings with impre...

Protection of pine sawtimber and sawn timber against blue stain in Poland
1983 - IRG/WP 3193
The purpose of this paper is the synthesis of more important results of basic and applied research that have been grouped in the following problems: 1.: Fungi causing blue stain in the pine wood, occurring in Poland. 2.: Moisture content changes of pine sawtimber and sawn timber as the factor of blue stain producing fungi development. 3.: Effect of sapwood moisture content on the degree of wood st...

The anatomical determination of wood samples found in the “Fürstengräber” from Lübsow (Poland)
2018 - IRG/WP 18-10930
The paper presents the results of anatomical research identifying three wooden fragments from the “Princes Graves” (“Fürstengräber”) in Lübsow, Poland. The research demonstrates that the wooden fragments are typical of wood harvested from European forests.
The physicals conclusions are important for the research of Jan Schuster, from the University of Lodz, Institute of Archeology, Pol...
