<DIV>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,</DIV>

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