I don't know I'm sure Monsanto put out[0] a lot of papers about how effective glyphosate is but another team decided to test glyphosate against the "inert" ingredients in roundup and found glyphosate was actually the weakest pesticide of the group.

Now, my pet theory is that they knew glyphosate wasn't that great, but talked it up in papers as a sacrificial anode sort of thing "gee shucks it looks like glyphosate based pesticides are harmful to humans (or bees, or fish, or) so we'll stop manufacturing that formulation."

But, Possibly due to academia, they have fanboys and cheerleaders and I think that's why it's still around and in heavy use even though we're not sure it's a good idea.

P. S. Just watch.
