Where exactly are you located? If you are spraying in a low mildew pressur=

e had very heavy mildew pressure and the results were somewhat different. =
This last year, was also a high pressure year. I had control but even with=
 weekly spraying, we had some outbreaks. These were controlled with fungic=
ide. Overall, the vinyard was not sprayed as is typical with conventional =
practice.

I talked to someone at SFI and he recommended that for heavy mildew pressur=
e, we spray as much as every day or at least every other day. This, of cou=
rse, is financially unfeasible. Spraying every two weeks would not give ad=
equate suppression of powdery mildew in a heavy pressure year in my experie=
nce. There would be some control but it would not be adequate in a large v=
inyard. I got most of my clients to agree to every ten days which seems to=

no situation where existing mildew was eradicated by CT. In addition, I ha=
ve seen vines sprayed with conventional fungicide designed for mildew eradi=
cation not get wipe-out after only one spray. Sometimes it takes two or th=
ree to wipe the stuff out.

  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
