Abstract: The goals of this study were to evaluate borate/amine/zinc formulations in wood for fungal decay protection as well as the permanence of zinc and boron in wood. Wood treated with each of four formulations of borate/amine/zinc prevented or decreased fungal degradation after a 12-week AWPA Standard soil-block test. For non-leached specimens, wood treated with borax/amine/zinc formulations required retention of 1.2% to prevent decay by Gloeophyllum trabeum (Gt) and Trametes versicolor (Tv), whereas that of DOT/amine/zinc formulations required 0.6% to be effective. For leached specimens, only DOT/ dicyandiamide/zinc formulation prevented decay by both Gt and Tv but required high loading of 5.4 to 5.5% chemicals. The other three formulations were ineffective against both fungi. Elemental analysis showed that decay protection of DOT/dicyandiamide/zinc formulation in wood after 2 weeks water leaching was attributed to higher boron and zinc contents than that of the other three borate/amine/zinc formulations. The leach-resistant zinc in the treated wood did not translate into effective decay protection compared with the copper formulations (Chen 2010).
