<p>The invention is concerned with a fungicidal composition for preserving freshly cut wood against blue stain and mold fungi attacks. The fungicidal composition according to the invention comprises an aqueous solution, emulsion or suspension containing: a) 5 to 10% by weight of urea, and b) 0.25 to 1.0% by weight of at least one monoquaternary ammonium compound of the general formula (I) wherein R1, R2, R3 and R4 are the same or different and each represents a straight or branched saturated or unsaturated alkyl group of 1 to 20 carbon atoms, alkylaryl group of 7 to 19 carbon atoms, aralkyl group of 2 to 27 carbon atoms or aryl group of 6 to 20 carbon atoms or alkylene oxide condensates of such groups, two or three of the substituents in combination with the quaternary nitrogen atom to which they are attached and optionally additional hetero atoms being capable of forming a saturated or unsaturated 5-, 6- or 7-membered heterocyclic ring, and X is a water-solubilizing anion, components a) and b) being present in a weight ratio comprised between 5:1 and 40:1.</p> |
