What is the primary danger associated with brown rot?

The primary danger associated with brown rot is that it structurally weakens the wood. Brown rot is a type of fungal decay that primarily affects the cellulose within the wood. As the fungus breaks down this critical structural component, it leads to a loss of strength and rigidity in wooden materials, making them brittle and prone to collapse or failure.

This form of decay is particularly concerning in structural applications like beams, joists, and other load-bearing elements in buildings. The compromised integrity of the wood poses significant risks, including safety hazards if structures become unstable. While other options mentioned can be factors in pest management and wood health, the most critical issue with brown rot is the reduction of the wood's structural integrity.
