Hello, I am curious as to whether anyone has seen or experienced an orange type mold growing on Southern Yellow Pine? It is very aggressive and seems to locate the moist portion of a piece of wood, but it will spread to areas with 15% or less mc. I realize this is contrary to all literature but we experienced this last year and it has started again this season. Thank you for any and all responses.

There is another forum thread with good info, you might look at that. Mold comes in lots of different colors, depending on what's in your region so the orange color is probably not the issue. If it is on lumber planed at 15%, then at some point that board was above 15% after planning (for example condensation within a package) or perhaps the board was adjacent to a wet board in the unit and the surface was wet enough for mold to grow.

Thank you for responding. I agree that the moisture content was above 15% at some point or in the wood in order to begin its growth cycle. I just know how to prevent the growth or if that is possible without drastically increasing processing costs. We use 1" thick sticks in our pre-cut stacks and it seems to love the dark spaces between rows where mc is the highest. Its nasty looking stuff and i do have pics if anyone would be interested in seeing them.
Thanks Again,
Jeff
