Resistance to Decay Fungi of Scots Pine Impregnated with Natural and Chemical Preservatives

IRG/WP 14-30650

S Yildiz, U B Şimşek

In this study, heart-wood and sap-wood specimens of the Scots pine which is naturally grown in Turkey were treated with natural (valex) and some chemical preservatives such as CCA - C (Copper / Chrome / Arsenic), CBA - A (Copper / Boron / Azole). The wood protective efficacies of these preservatives were investigated by means of fungi decay test (EN 113). As a result of the study it was found that the retention values of sap-wood samples better than the heart-wood samples. The highest percentage retention was obtained from the sap-wood samples treated with valex 3%, (20,89 kg/m3). Additionally, it was observed that the chemical preservatives (CCA - C and CBA - A) had positive effects on biological test in all variations. But valex especially in low concentration (1%) was exhibited negative effect for both heart-wood and sap-wood specimens.
