Mr Lubar, It is really great you added this article. In my  previous 
ramblings I did not want to make the article  too complicated.  Thanks-Russ

"Environmental Fate Of Glyphosate", published by the California  Department 
of Pesticide Regulation in 1998, shows all the breakdown products,  and 
also concludes that Roundup binds tightly to soil, resulting in little  
movement beyond the soil. It also mentioned the absence of any pre-emergent  
activity. This document appears to be well worth at least  skimming.

AMPA is the primary breakdown product of glyphosate. In  "Glyphosate and 
AMPA in Drinking-water --  Background document for  development of WHO 
Guidelines for Drinking-water Quality" (2004/2005), it  is concluded that "Under 
usual conditions, therefore, the presence  of glyphosate and AMPA in 
drinking-water does not represent a hazard to  human health."

"Monsanto themselves have privately admitted to  formulating it to break 
down to nitrogen"

What's the source for this  statement?

I use a flame weeder in some situations and Roundup in  others.  But I do 
appreciate facts rather than unsupported  statements.
