Jil and others -
I understand that the Roundup surfactant, polyethoxylated tallowamine, can
be highly toxic as per below. Does anyone have any insight into its behavior in
the environment in terms of issues such as lifetime (does it break down
quickly or not), toxic metabolites/breakdown products, etc.?? I know that
glyphosate is touted for among other things its rapid breakdown and now I'm
wondering about the surfactant. For example, if an area outside a buffer distance but
still not too far from a waterbody is treated, how much potential is there
for the surfactant to get into the water at potentially toxic levels? If the
surfactant breaks down rapidly into nontoxic products of course that would be
a good thing. Just curious... Cheers,
Steve Young

Hi,
Please see article below about the impacts of the surfactant
"polyethoxylated tallowamine" on amphibians. The surfactant is an
ingredient in Roundup. Glyophosate was not responsible for the frog kills.
Thank you,
Jil

In case you have not seen this yet. It is important to note that at the
bottom of the article, it notes that it is not glyphosate that causes the
problem, but the surfactant. This is something that is not new news,
contrary to the last line of the article. That is why there is Aqua Master
(formerly Rodeo), it is Roundup without the surfactant. The use of Roundup
in a manner such as done in this study would be a violation of the law.
