[QSAR] herbicide or pesticide database

[List for Members of Cheminformatics and QSAR Society]

EXTOXNET is a simple, free though rather comprehensive textual database on most pesticides 
and contains various toxicity data.

 http://extoxnet.orst.edu/pips/ghindex.html 

Another printed authoritive and the most comprehensive source  is "The Pesticide Manual" 14th 
edition. (It is available in searchable and frequently updated CD version.) You find it in all good 
libraries.

Side note: being this a ChemInfo QSAR discussion list, I caution about the uncritical use of LD50 
values in QSAR and related studies. The non-target toxicity data for most of the current pest 
control agents are ABOVE a certain value (say oral LD50 > 1000 mg / kg), so it is more of a 
´safety´ than a ´toxicity´ indicator required for registration.

Best regards,

Istvan
