Organic solvent preservatives. Essays on the ecotoxicology of new formulations
1991 - IRG/WP 3642
The knowledge on the ecotoxicological profile of wood preservatives become more and more important. The acute toxicity against aquatic organisms was examined for oil-borne preservatives, based on combinations of new fungicides (Tebuconazole, Propiconazole, Dichlofluanid) and insecticides (Permethrin, Cyfluthrin). These tests were conducted with fish, daphnia and algae. In principle the different f...
Suitability of cyfluthrin in wood protection
1992 - IRG/WP 92-3735
Cyfluthrin, a well-known and in agriculture and household widely used insecticide based on synthetic pyrethroides, is evaluated now concerning its suitability as insecticide in wood protection. An overview about the physical and chemical properties is given. Test results in accordance with European standards show the high efficacy and broad-spectrum activity of Cyfluthrin against wood rotting inse...
Glass splinters as physical termite barriers: Optimized material properties in use with and without insecticidal pretreatment minimizes environmental contaminations
1991 - IRG/WP 1476
The major advantage of physically acting barriers against termites using sand or cinder is to be impenetrable for a number of termite species by showing environmental compatibility in a high degree. The major disadvantage of these barriers is the ability of termites to build galleries over them. Glass or glass-like materials are showing optimum material properties: crushed to a particle size from ...
