Mike from Punta Gorda, Fl writes

Before install, I treated 3/4 plywood subfloor on bottom side with Bora-Care

Now that plywood is installed on treated joists, Is it necessary to treat top side as well?

Answer:

Bora-Care will only penetrate through the wood that it is applied to.  So if you have other wood placed on top of already treated wood you would need to treat that as well.
