What color does wood affected by brown rot typically appear?

• A. Light yellow
• B. Dark brown
• C. White
• D. Red

Answer: (B)

Wood affected by brown rot typically appears dark brown due to the specific types of fungi that cause this kind of decay. Brown rot fungi primarily break down the cellulose in wood, leaving behind lignin, which gives the wood its dark coloration. As the rot progresses, the wood loses its structural integrity and may take on a cubical cracking pattern and a darker hue. This contrast can help in identifying brown rot in comparison to white rot, which often leads to a lighter, more bleached appearance of the affected wood. Understanding this visual cue is essential for effective pest control and prevention strategies for structural integrity.
