Fipronil mainly induces Cl- flow by blocking the Cl-channel of the nerve membrane controlled by γ-aminobutyric acid receptors, causing extreme excitement of the nervous system and causing the death of the worm, achieving the control effect of a variety of economic pests.
Fipronil has the advantages of broad-spectrum and high efficiency. It has been widely used in many agricultural fields and is a commonly used pesticide for pest control.
Fipronil is mainly used in crops such as rice, sugar cane, potatoes, etc., and animal health is mainly used to kill parasites such as fleas and lice on cats and dogs.

Fipronil — CAS 120068-37-3
Fipronil is a phenylpyrazole-class broad-spectrum insecticide and acaricide that acts by blocking GABA-gated chloride channels in the insect central nervous system. It remains one of the most widely used actives in veterinary ectoparasite control (spot-ons, sprays) and public-health pest control (cockroach/ant baits, termite treatments), while its agricultural use is heavily restricted or banned in many countries.
