Dry rot is a condition of wood in which a fungus breaks down wood fibers and renders the wood weak and brittle. Excess moisture is the root cause of dry rot. Borate wood preservatives can be used to treat and prevent fungal growth in some situations. The most important way to prevent dry rot damage is to reduce or eliminate excess moisture. This may be as simple as repairing a leaky pipe or as complicated as stopping water infiltration through a basement foundation. A common cause of dry rot and termite damage is wood in contact with soil as occurs, for example, with a failed foundation. If moisture cannot be controlled, or if the dry rot fungus has gained a foot-hold, then wood should be treated to inhibit the growth of the fungus. Boric acid, or borate, is an excellent fungicide (a pesticide that kills fungi) against the dry rot fungus.
