V raziskavi smo določili minimalno fungicidno mejno vrednost borove kisline inbakrovega sulfata pentahidrata za tri glive rjave (Gloeophyllum trabeum, Serpula lacrymans in Antrodia vaillantii) in tri glive bele trohnobe (Trametesversicolor, Pleurotus ostreatus in Hypoxylon fragiforme). Kurativno učinkovitost smo določali tako, da smo okužene smrekove in bukove lesne vzorce za 10 min potopili v vodno raztopino bakrovih oziroma borovih učinkovin. Zatem smo jih postavili na sterilno hranilno gojišče in opazovali preraščnje. Rezultati kazejo, da so borove učinkovine boljsi fungicidi kot bakrove spojine. Minimalna inhibitorna koncentracija borove kisline v lesu za kurativno zaščito je približno petkrat višja od mejne inhibitorne koncentracije za preventivno zaščito.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
