Ouch!
Actually, I wasn't aware of use of derris as an insecticide, but had heard of it in a different context.
Perhaps we should be trying to square the circle of someone that says 'I'm organic' but wishes to use a poison to kill things.
Obviously misuse is the issue, so perhaps it's okay to go back to using paraquat...
I thought the ideal of being 'organic' was not to use harmful substances at all, and that we should all be striving towards that, rather than complaining when we're not allowed to use something that was once considered safe, but now is not. (Asbestos cigarette anyone?)
By the way, i've just harvested some of my leeks and parsnips which have been grown without using
any pesticides at all... so I won't starve, but I might smell funny
