Jeff,
Thank you again for your input. We are at a disadvantage being in
such a remote area that getting tea tested would be a major
undertaking. We do hope to get a microscope sometime. There could
well be bacteria and fungi present and working in our "soup to nuts
recipe" tea. We do use high levels of molasses and get temperatures
up to 88 degrees which led me to conclude that the fungi numbers
would be quite low.
I have just glanced at our most recent test spray and it looks like
the powdery mildew may be collapsing but it is inconclusive at
present. I'll check again tomorrow morning.
Regards,
Titel
