ATTENTION:Please check the 'Last Update' date on the federal and state data. Due to the social distancing and remote work going on around the country, we expect delays in getting the most up to date data. We want everyone to stay safe out there whether it is from COVID-19 or using unregistered pesticides. If you have questions about the data displayed, please contact the US EPA or the individual state pesticide registration department. We will be working hard to keep these websites available. If you have website issues, the best way to contact us is by email at: npirs@ceris.purdue.edu.

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 and territories who voluntarily provide their state registration data.

Update Frequency: State Product is updated as frequently as a state sends their registration data to NPIRS, generally daily, weekly or monthly. Federal Product is updated weekly.

Unique Features: All versions of state labels are available for viewing. Search results from Federal Product can be carried forward into State Product to identify corresponding state registrations.
