I contacted the PA Dept. of Agriculture (sorry for the long post):
"Dale,
To my knowledge, Rotenone is not approved for use in Pennsylvania. I have copied John Lake our pesticide registration expert on this email to confirm the availability of Rotenone in the State.
A private pesticide license is sufficient to apply pesticides to a pond on your property. Selling for profit does not impact the required license. However, a private license does not allow you to apply pesticides on the property of another.
I would also suggest speaking with the PA Fish and Boat commission
http://www.fish.state.pa.us/ about applying pesticide to a pond. I believe a permit is required.
Andy"
John Lake from their office confirmed "There is no PA registered rotenone product registered for aquatic use in the state at this time". So, I'm going to look at other options. Any thoughts on super-chilling the water in the winter with aeration / mixing? Hoop net?
Thanks again,
Dale
