The present invention relates to a method for controlling sapstain and mold in wood using a biocontrol agent having a high pH tolerance and an alkaline solution. Biocontrol agents that do not discolor wood may be introduced onto wood or wood products to prevent sapstain and mold. The biocontrol agent grows on the wood surface and protects the wood against attack by stain or decay fungi. The application of an alkaline solution containing a biocontrol agent having a high pH tolerance to the wood product is very effective in controlling stain or decay fungi. The alkaline solution raises the pH of the wood to a level which impedes growth of other wood-inhabiting fungi but does not inhibit colonisation of the wood by the biocontrol agent.
