The Derwent Crop Protection Registry File provides a unique
reference to all established chemicals indexed in the DCPU database.
DCRR covers approximately 8000 known chemicals; each record includes
the chemical's full name, Derwent registry name, its activities,
chemical substructure and chemical ring codes.
Use DCRR to find:
- all pesticides with a particular activity
- all pesticides having a similar structure
- which herbicides contain similar chemical ring code structures
- which chemical ring code structures are included in the chemical
Chloridaz
- the Derwent registry name for the chemical Chlorfenac-Methyl
Sources:
DCRR contains entries for all chemicals that are indexed at least
twice in the main Derwent Crop Protection File (DCPU).
