How does Brown Rot fungi affect wood?

Brown Rot fungi are particularly notorious for their ability to break down specific components of wood, namely hemicellulose and cellulose. This process results in the deterioration of the wood structure. As these crucial components are digested, the wood loses its strength and structural integrity, leading to an overall condition known as "brown rot".

This type of fungal decay causes the wood to shrink and darken in color, often resulting in a crumbly texture that is characteristic of brown-rotted wood. Unlike other forms of wood decay, such as white rot, which can bleach the wood and cause it to turn white, brown rot primarily focuses on these two components and does not promote growth or maintain structural integrity.

Understanding the role of Brown Rot fungi in wood deterioration is critical for those involved in pest control and wood preservation, as it informs the strategies used for preventing and managing wood decay in structures.
