What does sapstain fungi do to wood?

Sapstain fungi are responsible for causing discoloration in wood, typically manifesting as blue or green streaks. These fungi thrive in moist conditions and can penetrate wood without actually causing structural decay. The discoloration is primarily cosmetic, affecting the wood's appearance but not its strength or integrity.

While the strength of wood is not enhanced by sapstain fungi, the discoloration can significantly impact the market value and aesthetic appeal of wood products. It's important for those working in pest control and wood preservation to understand how sapstain fungi affect wood, as this knowledge helps in making informed decisions about proper treatment and prevention strategies.
