Eligibility Decision (RED) for the pesticide piperonyl butoxide, and opens a public 
comment period on this document.  
Piperonyl butoxide (PBO) is a pesticide active i ngredient that acts as a synergist. Synergists 
are chemicals which, while lacking pesticidal pr operties of their own, enhance the pesticidal 
properties of other active ingredients including py rethrins and pyrethroids. PBO is used in 
four general ways: preharvest and postharvest  uses on many agricultural crops; direct and 
indirect treatments of livestock animals and premises; treatments of commercial and industrial facilities and storage areas where raw and processed food/feed commodities are 
stored or processed; and mosquito abatement areas. EPA has reviewed piperonyl butoxide 
through the public participation process that  the Agency uses to involve the public in 
developing pesticide reregistration and to lerance reassessment decisions. Through these 
programs, EPA is ensuring that all pesticid es meet current health and safety standards.
