However, Rotenone is a lethal poison and it doesn't take much to kill a

Wasn't it because of the dangers of it going in water ways - it's
lethal to fish and all water living creatures.

Lots of things we use are lethal to waterlife, why should the powers that be
consider Rotenone for removal from retail sale? I bet professional gardeners
like the RHS at Wisley can and will still use it.
