Roundup was Cardamine hirsuta
Thu, 04 Apr 2013 16:38:57 PDT
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

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
