Roundup was Cardamine hirsuta

Dear Aaron, your right, I have also seen tons of roundup used by highway
departments and cities in Wisc. It has been used for years and if it was so
incredibly deadly there would be no one alive in large parts of the US. Of
course who knows what long term results will be.
One thing reading the letters, is now I know why we don't meet in one
location. I have never seen such passionate people in my life. But I agree
that everyone has a right to an opinion and free speech is important too. If
we have a convention I think the Directors better ban all weapons from guns
to switchblades or it could be a real bloodbath-Russ

One only needs to explore the literature. Germination tests were done on
various weeds in the 1970's in lab settings. Of a few things sampled, most
showed no differences when the seeds were treated with glyphosate.
Amaranthus retroflexus showed increased germination. Replicate these experiments and
see what happens with Cardamine hirsuta. More than likely, the germination
of this plant is due to increased light.

Plants treated with glyphosate that produced seeds showed reduced
germination and juvenile mortality --- that variegation so prevalent in roundup
sprayed plants is seen in seedlings of plants sprayed by it. One of the other
uses of roundup is for harvesting. Spraying a field of non-Ru-ready crops
kills them so they can all be harvested at once. The seeds of these plants
have roundup in them.

Another issue with roundup is the increased susceptibility to fungal
pathogens of all plants in areas sprayed. Lab tests have shown no effects on
growth, + or -, of fungi though....

In my area Roundup is dumped by buckets along road medians to kill
vegetation. Last year I saw this about 100 meters away from the Powell River in
Tennessee.

Nhu's suggested experiment is a goods first step to answering the question
of Roundup's effect on seeds. An actual controlled experiment is not
merely "scientific window-dressing" but a prerequisite for reliable discussion
of the subject. There are other factors that could be involved rather than
the direct action of Roundup on seeds; it could be that the suddenness of
the increase in light after spraying is the trigger, or maybe something that
the dying grass releases after being killed by Roundup but not after being
killed by other means, or maybe some other mechanism. There may well be
other observations that rule out some of these other factors, but a nice
simple experiment like Nhu's would go far towards making this a better
discussion.
