Let's be honest. If that is such a tiny amount and not likely to 
significantly affect the surfaces
treated and does not significantly  enhance penetration into whatever 
the product touches,
why would farmers use it?

Obviously, they think that even that tiny amount has an impact.  Are 
they wrong?

After Roundup spraying, even if glyphosate is entirely benign -- which 
is a separate
question -- what else can penetrate the wetted surfaces more easily, and 
for how long?

Applying soap and water is a very effective method of killing insects.  
Is a surfactant not similar to
a soap in its action, only very much more potent?
