Ted:
We are in the back reaches of the Monasee Mountains about 3 hours
out of Kelowna, B.C. The area of growing beds I referred to have had
lots of mildew for the past 3 years in a row. You may be correct
that it is a 'low pressure year' whatever that means.
I said we sprayed "at least" every 14 days; sometimes 6 days passed,
sometimes 10 sometimes 14. It depended on timing of tea and people
and weather. It seems that a vineyard could be sprayed everyday or
so fairly economically with a 5 to 10,000 gallon brewer and cheap
overhead shrub heads.
Have you used pyrophylite clay and rock phosphate in your recipes?
Again please realize that I am not making claims, only observations
and this all evolved from an anecdotal comment to Steve.

representative. The first time I sprayed, I had complete
suppression. Boy was I on a roll. The next year, we 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
fungicide. Overall, the vinyard was not sprayed as is typical with
conventional practice.

mildew pressure, we spray as much as every day or at least every
other day. This, of course, is financially unfeasible. Spraying
every two weeks would not give adequate suppression of powdery
mildew in a heavy pressure year in my experience. There would be
some control but it would not be adequate in a large vinyard. I got
most of my clients to agree to every ten days which seems to keep
most of the vinyard clean with isolated local outbreaks. I have had
no situation where existing mildew was eradicated by CT. In
addition, I have seen vines sprayed with conventional fungicide
designed for mildew eradication not get wipe-out after only one
spray. Sometimes it takes two or three to wipe the stuff out.
