Re: Cygon E

Hi,
I don't think anybody can be over cautious when using chemicals. The is a
very good web site run by several of your universities with a database of
chemicals, their toxicity to humans and wild life and what happens to them
once you spay them. I looked up Cygon (also called dimethoate) and it has a
couple of pages of info. The toxicity of the soil will depend on the weather
etc. 

The address for the site is http://ace.orst.edu/info/extoxnet/
The address for the page on Cygon is
http://ace.orst.edu/info/extoxnet/pips/dimetoa.p93

I hope this is of help
