The National Pesticide Information Retrieval System (NPIRS) is a collection of pesticide-related databases
available by subscription. Many subscribers use NPIRS to assist in registering pesticides and to develop marketing strategies
based on currently registered products or pending registrations. Others use NPIRS for pesticide registration information and
to identify products currently registered in states.
NPIRS is comprised of three major databases including the Pesticide Document Management System (PDMS), Federal Product and State
Product. The Federal Product database contains information pertaining to all federally active, cancelled, and transferred products and
searches are initiated by selecting one of the available search options. State Product searches are initiated by selecting
a specific state first before selecting additional search options. All Site of Application and Pest to be Controlled information
is derived from the federal master label.
The PDMS database was first developed by the U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs (OPP) and used as
their primary tool for managing the large volume of documents submitted to them, primarily in support of product registrations.
Document information includes a master record identifier (MRID), trade secret status, submitter and laboratory information, chemistry
and subject indexing, guidelines, author, and related MRID information.
Data Sources: U.S. Environmental Protection Agency (EPA), Office of Pesticide Programs (OPP) and U.S. states
and territories who voluntarily provide their state registration data.
Update Frequency: PDMS and Federal Product are updated weekly. State Product is updated as frequently as a
state sends their registration data to NPIRS, generally daily, weekly or monthly.
Unique Features: Many of the databases have the ability to interact with other databases while maintaining
search results. For example, search results from Federal Product can be carried forward into PDMS for the purpose of identifying
corresponding studies. These same results from Federal Product can be carried forward into State Product to identify corresponding
