METHODS AND COMPOSITIONS ADDRESSING SAPSTAIN, WOOD DEGRADATION, AND PESTS AFFECTING WOOD

摘要

The present invention is directed to compositions and methods for addressing problems of sapstain, wood decay, and/or pests in wood and wood-based materials. The invention relies on the use of a group of active compounds which are introduced into wood or wood-based materials. Various techniques for introducing different compositions are discussed. Different combinations of techniques and compositions can be used to provide short- to long-term protection to wood and wood-based materials, and in some instances may be used to treat materials already affected by sapstain, decay, and/or pest populations. The active compounds comprise one or more members of a group comprising: terpene derivatives such as derivable by the chemical or bio-technology processing of alpha - and beta - pinene; beta - unsaturated aldehydes and ketones; disubstituted mono-phenols, and mono-substituted diphenols of general formule (1), where: R1 = alkyl, aryl, alkoxy; R2 = H; R3 = alkyl, aryl, alkoxy; or: R1 = alkyl, alkenyl; R2 = H; R3 = OH; or: R1 = alkyl, alkenyl; R2 = CH3; R3 = OH.
