From duane campbell:
I'm wondering whether anyone has read Monsanto's response to this report
before chiming in. Or the report itself. Or looked into Open Source Earth,
admittedly difficult because they've taken their web site down.
Frankly when an organization with a history of anti-chemical
back-to-the-earth campaigning comes out with a report claiming that numerous
governmental and quasi-governmental organizations with general
anti-chemical, anti-GM, anti-business tilts have been hiding evidence of the
dangers of a chemical herbicide, I am suspicious.
So to answer the question, yes, I still suggest the use of glyphosate with
appropriate cautions, among which is the admonition that they shouldn't
drink it when pregnant.
From Lorraine Ballato: Yes, I do recommend it for only one problem: to get rid of persistent and resistant vines and only by using floral tubes. The instructions are given verbally via demonstration so there is little room for misunderstanding: cut the growing tip of the vine on a nice, long diagonal slice, making sure you have enough of the vine to fit the length of the tube plus about 2-3 inches. Fill the tube undiluted about 80% full, put the cap on. Insert the freshly cut end into the poison, making sure it is secure and practically at the bottom of the tube. Insert the pointed end of the tube into the ground, making sure it is securely capped and the tube is stable. Cover the floral tube with a rock, some kind of nursery pot, terra cotta, etc. so that it is not inadvertently stepped on or investigated by a child, pet, etc. If you have a notoriously curious family member, take other appropriate measures. Check back in a day or two to see the effect along the length of the remaining vine to be s
ure it's working.
This method really works without impacting surrounding vegetation, the soil, the gardener, etc. It's very labor intensive and takes more than one season to eradicate things like bittersweet, Japanese knotweed, unwanted wisteria, and the like.
*******From Doreren Hwoard: About Round-Up. I quit using it years ago when I discovered that the salts
persisted in soil and were transferred by the roots of dying weeds. I read a study in an obscure scientific journal, one of the 100's my husband reads, after he pointed it out to me. Root transfer was terrifying to me and bad for the soil food web, so I immediately stopped using the stuff. I've
mulched thickly and pulled a ton of weeds since.
From Carolyn Ulrich; So I went to my local Ace and bought a small spray bottle of Round Up,
applied it to the leaves on a rare windless day in April at a distance of
about 3-4 inches. Some dieback but decided it needed a second application,
and more progress ensued. Now I no longer feel overwhelmed. I pull some
leaves that I see (knowing full well that the roots are still there,
probably going down 12 inches deep) and put black pots and flats over other
plants that are at the back of the border and not visible to the street, but
the situation is better than it was.
From LCS's Myth about Glyphosate; no evidence was found to suggest root
translocation of any of the herbicides â applied to thousands of cut stems – to nearby untreated trees.
The Bottom Line
â¢ Unrelated plants are unlikely to form root grafts
â¢ Field research indicates that glyphosate and other translocatable herbicides do not cross root
grafts in healthy trees
â¢ Fungal vectors can breach root grafts through degradative enzymatic activity
â¢ Root grafts that have already been breached by fungi may serve as conduits for herbicide
translocation as well

For a link to a google document that highlights potential health effects
from exposure to roundup go to:
Separately, Green Peace/GM Freeze has just come up with another important
report on both the health and environmental impacts from Roundup.

âIncorrect claim about biological availability of glyphosate
The UK Pesticides Safety Directorate (PSD) notes that the issue of a
waiting period between glyphosate spraying and re-entry into fields in
order to protect humans, livestock, and plants, is not properly dealt
with in Germanyâs DAR. However, the PSD immediately dismisses this concern:
This should not be an issue for glyphosate as it is not usually
biologically available once it contacts soil.349
But this claim was not true even at the time of the DAR. A 1983 study
showed that glyphosate persists in sandy loam soil and is not
inactivated in the 120 days prior to planting. Plants growing in the
glyphosate-treated soil showed decreased nitrogen fixation, root nodule
numbers and root weights â indicating that glyphosate was biologically
available and toxic to plants 120 days after application.350
A new risk assessment should address the issue of the re-entry period.â

âIncorrect claim about biological activity of AMPA
Monsanto says AMPAâs long persistence in soil is of no âregulatory
concernâ because âAMPA is biologically inactiveâ.351 But a 2004 study
showed that AMPA causes injury to glyphosate-tolerant and
non-glyphosate-tolerant soybeans. Findings are the same when the AMPA is
deliberately applied and when it forms from the breakdown of applied
glyphosate. The study concludes that soybean injury to
glyphosate-tolerant soybeans from glyphosate is due to AMPA formed from
glyphosate degradation.352 Therefore AMPA is biologically active.
It is clear that the documents on which the existing approval of
glyphosate is based are out of date and out of touch with current
scientific knowledge and farmer experience.â
