Is PT wood a fungicide?

My Foot Smells · July 1, 2015

I've noticed not as many mushrooms pop up in my PT wood beds. Have a variety of natural cedar, stone, and PT wood (CCA). Also have one plant on death bed with blight in cedar, but PT bed seems healthy - maybe coincidence?

Seems like fungicides are now copper based, which I've never used, only squirt with BT once a year if necessary.

I'm pretty much all natural, but do use PT wood to give long life to raised beds. I know there are a lot of purist that do not use PT and question affects; but research has shown very, very, very minimal leaching of the micro-anodized copper treatment with zero harm.

Tip of the day: Place a plastic flamingo in front of west facing tomatoes lower cluster to prevent sunscald.
