) and red maple (Acer rubrum) cubes were pressure treated with copper ethanolamine followed by sodium dimethyldithiocarbamate (SDDC) with elemental copper retention levels varying from 0.8 kg/m3 to 8 kg/m3. The decay resistance was determined using a laboratory soil block test with pure fungus culture according to modified AWPA standard E10-91. A 4.0 kg/m3 elemental copper retention was sufficient to protect treated samples against Gleoephyllum trabeum, Pleurotus ostreatus, Trametes versicolor, Irpex lacteus, and Chaetomium globosum. But higher elemental copper retention (4.5 to 5 kg/m3) was needed for protection against the copper tolerant brown rot Poria placenta.

ins Holz eingebracht. Die Abbauresistenz wurde mittels Bodentest mit reinen Pilzkulturen nach dem AWPA-Standard E10-91 durchgeführt. Ein Kupfergehalt von 4,0 kg/m3 bot ausreichenden Schutz gegenüber Gleoephyllum trabeum, Pleurotus ostreatus, Trametes versicolor, Irpex lacteus und Chaetomium globosum. Gegenüber dem Braunfäulepilz Pori placenta war jedoch ein höherer Kupfergehalt erforderlich (4,5 bis 5 kg/m3)
