Derris dust being withdrawn

Derris should not have been on sale since October 2008 and should not be stored or used after October 2009. Although I did see some in a local garden centre a few months ago.

This stuff is completly indiscriminate and wipes out pollenators and predators aswell as pests. If it gets into water the fish are dead. Glad to see the back of it.

Aldrin, dieldrin, DDT were all lamented as irreplacable when they went.

One thing I never understand is why bordeaux mix is happily applied by organic enthusiasts. It contains copper salts.
