The National Pesticide Information Retrieval System (NPIRS) is a collection of pesticide-related databases available by subscription. Subscription use of NPIRS derived data can be used to assist in registering pesticides, identify products currently registered, and to develop marketing strategies based on currently registered products or pending registrations.
NPIRS is comprised of three major databases including:
Data Sources: U.S. Environmental Protection Agency (EPA), Office of Pesticide Programs (OPP) and some U.S. states and territories. CERIS receives state pesticide registration data from states who voluntarily send their data. Some states provide data on federally-exempt Section 25b and other pesticide products that do not require federal registration but are required to be registered in states. Additionally, some states provide information pertaining to 'state restricted' use products. Associated federal registration data is included for state registered products.
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 state registrations.
Information NOT available in NPIRS: Inert ingredients; dilution rates; re-entry times; exposure treatments; sales data; specific formulation data; application rates; endangered species information; repeat application or rotation data; establishment numbers.
General NPIRS annual subscriptions include access to the three databases and are focused on the number of searches expected to be performed over the year:
State Data Providers, Government Agencies, and Universities annual subscriptions are based on the databases they would like to access during the year:
