>> Most of the damage to aquatic and riparian (stream edge) invertebrates
was from 'inert' ingredients such as the surfactants and adjuvants used in
herbicides and insecticides.

The amount of damage to stream ecology by pollutants (including plant
protection products) is astounding.  I've spent considerable time in
sampling stream insects (aka benthic macroinvertebrates) in my area.  One
doesn't notice a difference in the stream simply by looking at the surface.
However, pollution can turn the streams into virtual deserts underwater.

Bob, I also cringe at Section 18 exemptions for general use of products.
