This paper presents a study on the resistance of wood composite boards, glued with silicone adhesive and obtained from chips of Scots pine Pinus silvestris L. and willow Salix viminalis L., to basidiomycetes and mould. The boards were protected in the production processes with fungicides based on metal nanoparticles, as well as on derivatives of 1,2,4-triazole, benzimidazole, and thiazole. The biocides have been added to the silicone adhesive prior to pressing the boards, in an amount of 0.6% by weight. Mycological examination was carried out against white-rot fungi Trametes versicolor and Pleurotus ostreatus and brown-rot fungus Coniophora puteana and against a mixture of mould and Chaetomium globosum fungi. The developed ecological composite boards protected with fungicides on the basis of azole demonstrated full resistance to basidiomycetes and mould. They can be used in wooden building, in high humidity conditions conducive to the occurrence of biological corrosion of lignocellulosic materials. Application of copper nanoparticles or silver nanoparticles as a biocide did not result in protection of the composite boards to decay and moulds fungi.
