The tea is poo pooed by Brinton because he says that other, less expensive, less labor consuming methods will produce the same results. Will published on this in BIODYNAMICS in the early 90's.Also stated by York is that even bd is not an answer in and of itself for a system as complex as a monoculture as an overhybridized vineyard.
York's message has always been, in any situation, that the preps are NOT magic, that they are a necessary input to a fully developed horticultural needs of the crop and a mature agriculural understanding of the needs of the soils. Practical as he is, one never hears of him creating a scenario in which the preps are left out. That said, York will still tell you that the preps will not work miracles by themselves.
Saddest news I had late last week was that JPI has had no increase in inquiries after the Alt. Vit Conference.
What about you, Steve? Have you gotten much follow up?
