Minimal remedial fungicidal concentrations of boric acid and copper sulphate pentahydrate for three brown (Gloeophyllum trabeum, Serpula lacrymans and Antrodia vaillantii) and three white rot (Trametes versicolor, Pleurotus ostreatus and Hypoxylon fragiforme) fungi were determined. Remedial efficacy was determined on infested spruce and beech wood specimens, which were immersed into selected copper- or boron-based preservative solutions for ten minutes. The treated specimens were transferred to nutrient medium and fungal growth was monitored. The results showed that boron compounds where better fungicides than the copper ones. furthermore, minimal remedial boron fungicidal concentration is approximately five times higher, than the preventive minimal inhibitory concentration.
