Penflufen as a wood preservative against wood- destroying basidiomy cetes

A process for protecting wood and wood-comprising materials against attack or destruction by wood-destroying basidiomycetes, the process comprising treating wood or wood-comprising material with a biocide composition comprising biocides, the biocides consisting of:

• penflufen, a salt thereof, or a combination thereof;
• and
• copper carbonate,
• wherein the basidiomycetes comprise holobasidiomycetes, and the wood or wood-comprising material is treated with a concentration of the biocides in a range of from 0.001% to 5% by weight, based on the weight of the wood or wood-comprising material.
