Oh really? Since when does Roundup kill anything that doesn't
have chlorophyll? And which soil bacteria have it?



Tsu

yes thanks... this is my understanding of how RU works too...

You mean your understanding of Monsanto's explanation. Glyphosate
has well-documented deleterious effects on soil micro-organisms. You
and Tsu need to wake up.


Synergy between Glyphosate application and Fusarium species.

This is research from the early 1980's that shows a definitive
relationship between the application of Glyphosate and the
post-application growth of Fusarium in the soil. This shows that the
soil can remain poisoned -not only as a direct effect of Glyphosate,
but by the secondary effects of an artificially-stimulated and
enlarged growth of mycotoxin-producing Fusaria.

In other words, the Glyphosate kills various soil micro-organisms
(which in of itself may be deleterious), some of those which keep
naturally-occurring Fusaria in check. The Fusaria then take over,
contaminating the soils with mycotoxins for an undetermined amount of
time, and can produce noticeably lower yields in the consecutive
crops.

Thus, ecologies that are being sprayed with Glyphosate, especially in
the Amazon area, the "lungs of the planet," may be at risk, not just
from the primary effects of Glyphosate, but these secondary effects as
well.
