Stan, I am unaware of any field study evidence that contradicts
Bayers claims; e.g. "When used according to the label, Poncho
[clothandin] poses no unacceptable risk to earthworms."
On page 14 of this EPA Environmental Risk Assessment for clothianidin
it says: http://www.scribd.com/doc/46041897/Clothianidin
"Subchronic invertebrate toxicity studies showed that clothianidin
adversely affected earthworm mortality and body weight (LC50 = 15.5
ppm) and its degradates reduced body weight (LC50 = 982.6 ppm).
There were no apparent effects of clothianidin on earthworm
reproduction or population dynamics."
In this 3 minute video the owners of a South Dakota based chain
of pesticide dealerships show us a corn field they describe as
being "just lit up with with earthworm populations"
farmers. http://www.youtube.com/watch?v=a13QsgMj4h4
