PURPOSE: A method for protecting wood by treatment with sorbic acid and/or one or more salts of sorbic acid is provided. CONSTITUTION: Immersion Impregnation with Aqueous Potassium Sorbate Solution Air-dry pine boards are dipped into a solution of 30% potassium sorbate in water for event, visible soaking of the surface. After the treatment they are air dried. The boards are then stored in the open and only protected against direct rainfall at usual room temperature together with untreated boards for three weeks. After completion of the storage the untreated boards have intensive blue stain infection, which covers virtually the entire surface, while the treated boards, despite storage directly next to the infected boards, remain free from fungal infection. Compared with fresh wood, there is only a staining to give a pale brown color.
