The NPIRS State Pesticide Information Retrieval System (NSPIRS) is a subset of NPIRS
available by subscription. Many subscribers use NSPIRS for pesticide registration information and to identify products
currently registered in states. Subscribers include state regulatory agencies, universities, regional EPA offices, and
registrant companies. Several companies subscribe to NSPIRS for the ability to view all versions of state labels submitted
through ALSTAR.
NPIRS 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.
Searches in NSPIRS are initiated by selecting a specific state first before selecting additional search options. Numerous search options
make it easy to navigate the state's product data and with a variety of display options, the data can be viewed in several formats.
All Site of Application and Pest to be Controlled information is derived from the federal master label.
Data Sources: U.S. Environmental Protection Agency (EPA), Office of Pesticide Programs (OPP) and U.S. states
