Any experience with pre-emergence and how they affect the bacterial and
fungal populations within the soil after the product is applied.
products such as casaron, Ronstar or Surflan? Information about the
timing of applications. such as CT before, during or after applications
of the above type products.
Thanks for input.

The important point is the words I said in the last message - GOOD tea.
A tea with adequate sets of organisms. Adequate organisms numbers are
on the SFI report. We have tested these levels of organisms, and have
shown in our testing that 5 gal per acre is adequate.
Then you need to know the right application timing. If you have disease
present in the system, you need to apply weekly until the plants are
protected and disease not longer can reach the plant. Then back off to
fewer applications.
What if someone applies herbicide? Then you have just wiped out the
orgnaisms and have to reapply. What about a fungicide? Insecticide?
They all harm the organisms, and you would have to reapply the
organisms.
We were just looking at data tonight where the grower said they had
never applied any pesticide, but the organisms data kept saying
otherwise. We then looked at the operational log info, and right there
it was - sulfur spray. What do people think a sulfur spray, or a copper
spray are for?
