Maybe that's where the misunderstanding lies. 1/2 cup
non-ionic surfactant diluted into 10 gallons of water 
and applied over 1 acre of vegetation should not (based 
on my experience of being a spray applicator) be capable
of killing hardly any insects.  

Show and tell videos may be the way the ag chemical industry
can convey these principles to professors, grad students,
pollinator protection groups, beekeepers and other folks
who lack chemical application experience.  Maybe I'll
pick up a pint of surfactant at the local ag chem dealer 
tomorrow and try to make a video since I need to do
some Roundup spraying in my own yard anyway.
