So sulfur applied to the soil, either in granular
or wettable form is harmful to the fungi in the soil? Sulfur is used in many
lawn applications to open the soil, lower the pH, and chelate some nutrients. Is
sulfur helpful to the lawn, partially, because it gives the bacteria the
upperhand over the fungi population? What does this do to the biology, or fungi,
necessary for the trees growing in the lawn?

Reports in the scienitific literature say copper is
toxic to a number of bacteria at 3 ppm. As far as I have been able to
discern, it is the bacteria that are more susceptible to copper than the
fungi. But we have not done testing on copper concentrations in tea,
mostly because I am happy with the research papers on copper toxicity.
It's the sulfur that seems to take out many of the beneficial
fungi. We have some observation of this, but also a fair number of
research literature papers showing the same thing.
