ANTIFUNGAL PROPERTIES OF NEW IMIDAZOLIUM CHLORIDES AGAINST CONIOPHORA-PUTEANA (SCHUM-FR) KARST, TRAMETES-VERSICOLOR (L-FR) PILAT AND CHAETOMIUM-GLOBOSUM (KUNZE-FR)

3-Alkoxymethyl-1-alkylimidazolium chlorides showed antifungal activity against Coniophora puteana (Schum.: Fr.) Karst., Trametes versicolor (L.: Fr.) Pilat and Chaetomium globosum (Kunze: Fr.). The effective do ses of the ED50 the ED100 and the LD were measured by the malt-agar me thod. 1-Decyl-3-hexyloxymethylimiazolium, 3-butoxymethyl-1-decylimidaz olium, 1-decyl-3-decyloxymethylimidazolium, 1-decyl-3-pentyloxymethyli midzolium, 1-decyl-3-heptyloxymethylimidazolium, 3-decyloxymethyl-1-he xylimidazolium, 1-octyl-3-octyloxymethylimidazolium, 3-butoxymethyl-1- dodecylimidazolium and 3-hexyloxymethyl-1-octyloxymethyl-imidazolium c hlorides show potential as new wood preservatives. Fungicidal values d etermined on the wood of pine, spruce, beech and birch (from 0.8 kg/m( 3) to 5.5 kg/m(3)) indicate the high biological activity of the new he teroaromatic ammonium compounds against wood decaying fungi. The poten tial of imidazolium chlorides to fix in the wood of pine (Pinus sylves tris L.), beech (Fagus silvatica Link) and birch (Betula verrucosa Ehr h.) confirms their usefulness for wood protection.
