Abstract

Na področju biocidne zaščite lesa je zakonodaja vedno strožja, vse večja je tudi okoljska ozaveščenost uporabnikov. Smiselno je razvijati človeku in okolju bolj prijazne ciljno usmerjene biocidne pripravke. Izvedli smo zaščito lesenih vzorcev z 8 novejšimi biocidnimi pripravki po standardu SIST EN 152/1 in preučili učinkovitost biocidnih pripravkov proti glivam modrivkam. Lesene vzorce smo pripravili iz beljave bora ( Pinus sylvestris ) po standardu SIST EN 152/1. Biocidni pripravki, razen enega ( RB), so vsebovali kombinacijo IPBC-ja in propikonazola. Preučili smo tudi vpliv umetno pospešenega staranja na stabilnost pripravkov. Poizkus smo izvedli s testnima glivama Aureobasidium pullulans in Sclerophoma pithyophilla, katere predpisuje standard SIST EN 152/1. Po 6-tedenski izpostavitvi vzorcev v rastni komori smo ocenili stopnjo pomodrelosti. Umetno pospešeno staranje je poslabšalo učinkovitost vseh biocidnih pripravkov. Izjemi, pri katerih je staranje minimalno vplivalo na njihovo učinkovitost, sta bila vzorca zaščitena na testni površini z biocidnimi pripravki - Vi in IPBC+P+A. Ugotovili smo, da je najučinkovitejši biocidni pripravek - Vi.

Secondary title:	Efficiency of new biocid preparations against blue stain fungi
Secondary abstract:	In the field of biocide protection of wood the legislation is more and more rigorous; environmental awareness of users is getting high. That is why it is reasonable to develop more environment and human friendly wood preservatives. Protection of wooden samples was performed using 8 new biocide formulations, according to standard SIST EN 152/1. The efficiency of biocide preparations against blue stain fungi was investigated. Wooden samples were prepared from pine sapwood ( Pinus sylvestris ) according to standard SIST EN 152/1. With the exception of one (RB) , biocide preparations contained combination of IPBC and propiconazole. The impact of artificially accelerated aging on stability of biocide preparations was also studied. The experiment was done with test fungus Aureobasidium pullulans and Sclerophoma pithyophilla including standard SIST EN 152/1. After being exposed for 6 weeks in growth chamber, the degree of turning blue was evaluated. Artificially accelerated aging impaired the effectiveness of all biocide preparations. Exceptions, where aging had minimum impact on their effectiveness, were just the samples protected on surface areas with Vi and IPBC+P+A biocide preparations. We found out that the most effective biocide preparation was Vi.
