This tool is a searchable version of the USDA ARS Pesticide Properties Database. For the convenience of RAIS users, chemical and physical properties for 334 widely used pesticides are organized into simple sections by parameter. Every effort has been made to accurately replicate the USDA data; however, minor updates have been made (for example, deprecated CAS numbers have been updated). In addition to the USDA properties, the results first show the RAIS chemical information followed by the ARS data that are presented in the tables. USDA reports that these values were last updated on October 1, 2001.
