ABSTRACT:
This invention concerns a treatment for preserving or protecting moist wood against attacks from microorganisms (fungi) with the use of evaporable or sublimable ammonium salts. The protection is obtained by distributing the salts close to the wood so that the salts form an atmosphere around the wood in which the microorganisms cannot develop. The treatment is of special interest for moist wood during a storage period until it has been dried and is not further attached by fungi.
