Spray Adjuvant Chemical Formulation Identity Disclosure

The Department of Pesticide Regulation requires the registration of spray adjuvants prior to sale or use in California. Under California law, spray adjuvants are considered pesticides [California Food and Agricultural Code (FAC) section 12753(a)] and are broadly defined to include products intended for use with another pesticide to aid in the application or effect of the other pesticide (FAC section 12758). This notice provides guidance to registrants of spray adjuvants on three aspects of chemical formulation identity disclosure: (1) the Product Formulation Information (PFI) form; (2) the label ingredient statement; and, (3) acceptable chemical nomenclature and naming conventions.
