Abstract
Investigation of the use of impregnating formulation with propolis extract and organosilanes in wood protection – biological analyses. The paper presents results of mycological tests of wood treated with a protecting formulation based on propolis extract and silanes (methyltrimethoxysilane and (trimethoxysilyl)propyl methacrylate). Treated wood exposed to C. puteana exhibited resistance to the examined fungus and was classified as durability class 1 (“very durable”), according to the EN 350 standard. Fungistatic properties were also observed when treated wood was leached, according to the EN 84 standard and after exposure to the fungus. Results of the ergosterol assay, in the form of ERG reduction, in treated wood samples after exposure to C. puteana also confirmed fungistatic properties of the tested formulation. The formulation containing propolis extract and silane proved to be an effective constituent of biocide-free wood preservatives. Keywords:
