Here are some old posts regarding Roundup that may have something
useful.

For good information on Roundup and court cases go to Pesticide Action
Network North America. Web site
http://www.gks.com/library/pesticide/panna.html

Then go down to PESTIS Database and do a search for roundup. ( Submit
query to PESTIS now) you will find things such as this:

Ten reasons to "NOT" use roundup.

Compiled by Caroline Cox, Northwest Coalition for Alternatives to
Pesticides- (NCAP)

Roundup, and related herbicides with glyphosate as an active
ingredient, are advertised as products that can "eradicate weeds and
unwanted grasses effectively with a high level of environmental safety."
However, an independent, accurate evaluation of their health and
environmental hazards can draw conclusions very different from those
presented in the ads. Consider these facts:

1. Glyphosate can be persistent. In tests conducted by Monsanto,
manufacturer of
glyphosate-containing herbicides, up to 140 days were required for half
of the applied glyphosate to break down or disappear from agricultural
soils. At harvest, residues of glyphosate were found in lettuce,
carrots, and barley planted one year after glyphosate treatment.
2. Glyphosate can drift. Test conducted by the University of
California, Davis, found that glyphosate drifted up to 400 meters (1300
feet) during ground applications and 800 meters 12600 feet) during
aerial applications.
3. Glyphosate is acutely toxic to humans. Ingesting about 3/4 of a
cup can be lethal. Symptoms include eye and skin irritation, lung
congestion, and erosion of the intestinal tract. Between 1984 and 1990
in California, glyphosate was the third most frequently reported cause
of illness elated to agricultural pesticide use.

4. Glyphosate has shown a wide spectrum of chronic toxicity in
laboratory tests. The National Toxicology Program found that chronic
feeding of glyphosate caused salivary gland lesions, reduced sperm
counts, and a lengthened estrous cycle (how often an individual comes
into heat). Other chronic effects found in laboratory tests include an
increase in the frequency of lethal mutations in fruit flies, an
increase in frequency of pancreas and liver tumors in male rats along
with an increase in the frequency of thyroid tumors in females, and
cataracts. (ne fruit fly study used Roundup; the other studies used
glyphosate.)

5. Roundup contains toxic trade secret ingredients. These include
polyethoxylated tallowamines, causing nausea and diarrhea, and
isopropylamine, causing chemical pneumonia, laryngitis, headache, and
bums.

6. Roundup kills beneficial insects. Tests conducted by !he
International Organization for Biological Control showed that Roundup
caused mortality of live beneficial species: a Thrichgramma, a predatory
mite, a lacewing, a ladybug, and a predatory beetle.

7. Glyphosate is hazardous to earthworms, Tests using New Zealand's
most common earthworm showed that glyphosate, in amounts as low as 1/20
of standard application rates, reduced it- growth and slowed its
development.

8. Roundup inhibits mycorrhizal fungi. Canadian studies have shown
that as little as 1 part per million of Roundup can reduce the growth or
colonization of mycorrhizal fungi.

9. Glyphosate reduces nitrogen fixation. Amounts as small as 2
parts per million have had significant effects, and effects have been
measured up to 120 days after treatment. Nitrogen- fixing bacteria
shown to be impacted by glyphosate include a species found on soybeans
and several species found on clover.

10. Roundup can increase the spread or seventy of plant diseases.
Treatment with roundup increased the severity of Rhizoctonia root rot
in barley, increased the amount and growth of take-all fungus, a wheat
disease), and reduced the ability of bean plants to defend themselves
against anthracnose.

These facts about Roundup are taken From a two-part article about the
health and environmental hazards of glyphosate published in NCAP's
Journal of Pesticide Reform. Copies of the article, with complete
references for all of .the information presented, are available from
NCAP for $2.00. NCAP, PO Box 1391; Eugene, OR 97440; (541) 344-5044.

Sorry John but its time for a little balanced scientific reasoning (of
which you appear to have very little).

You quote residues....parts per million or billion are harmless.

> 2. Glyphosate can drift.

Again...but in what concentration?

So is 3/4 cup of table salt but should we ban it too?

again....out of context and irrelevant

The dose makes the poison...see above

Don't confuse lab tests with field studies...lab tests are notoriously
impractical.

I have no experience with your other points, thus am unqualified to
comment. However, I would like to point out that glyphosate will
probably go down in history as modern farming's safest and most
effective single product. End of story. Why do you people have such a
problem with organic chemicals, but will happily use seaweed extract etc
which is usually untested and occasionally full of arsenic, selenium
etc?
