Bifenthrin (Ref: FMC 54800)
Last updated: 12/01/2021
(Also known as: bifenthrine; biphenthrin; biphentrin; biphenate)

SUMMARY
Bifenthrin is a pyrethroid insecticide used to control a range of pests. It has a low aqueous solubility and is volatile. There is a low risk of groundwater contamination based on its chemical properties and it is not persistent in soil. There are some concerns about bioaccumulation and the pesticide shows a high oral toxicity to mammals as well as being an endocrine distupter and a neurotoxicant. It is toxic to birds, most aquatic organisms, honeybees and earthworms.
GENERAL INFORMATION
Description
