Piperonyl butoxide (PBO) is a pale yellow to light brown liquid[1] organic compound used as a synergist component of pesticide formulations. That is, despite having no pesticidal activity of its own, it enhances the potency of certain pesticides such as carbamates, pyrethrins, pyrethroids, and rotenone.[2] It is a semisynthetic derivative of safrole.[3] Contents 1 History 2 Uses 3 Mechanism of action 4 Regulatory 5 Hazard assessment 5.1 Acut...
