Welcome of the UH Agricultural Substances Database website; a comprehensive source of data for synthetic pesticides (PPDB), biopesticides (BPDB) and veterinary substances (VSDB). These databases can be accessed via this page. Data for other related substances such as adjuvants, biostimulants and wood preservatives are also available in the PPDB. The PPDB is also available via an IUPAC branded portal. Metabolite data is available via the specific substance record or via the database search facility.

	Pesticide Properties Database (PPDB): The main PPDB website that includes chemical identity, physicochemical, human health and ecotoxicological data. Click here to access this database		IUPAC PPDB: The IUPAC-branded version of the PPDB. This contains the same information as the main PPDB website but using IUPAC-branded delivery pages.

These databases have been developed and are managed by the Agriculture and Environment Research Unit (AERU) at the University of Hertfordshire for a variety of end users to support risk assessments and risk management.
