Sometimes they will use this compound Timbor to fight the fungus.
The chemical is also here. Compare an MSDS (Material SAfety Data Sheet)on it
Best of luck finding info on it, poria. I've tried our state, not much help, the clerk had not even heard of it when I called. Sometimes its considered a "pest", hence look under pest control etc. I did hear a guy at UCRiverside studies it, but unconfirmed.
I'm ready to start growing it myself in a fish tank to get info on it.
I've come across it in my work as an Industrial Hygienist about five or six times. Amazing organism. What an appetite for wood! And the way it can dissolve a thick wooden beam in a home shocks me. If you need some links, let me know.
