This paper presents the results of tests of the effectiveness of action of new imidazolium and bis-ammonium ionic liquids against Basidiomycotina and Ascomycotina wood-destroying fungi. All the investigated ionic liquids showed high fungicidal action against Coniophora puteana. In order to characterize the influence of ionic liquids on mechanical wood properties, the compression strength along the grain was investigated. The obtained results showed that impregnation of Scots pine sapwood with ionic liquid: [1,9-(2,8 dioxanenano]bis(dimethyloctylammonium nitrate) had no negative effect on the compression strength parallel to grain. The investigated compounds characterised by thermal stability, may be applied as biologically active components of wood impregnates in combination with other biocides.
