Fipronil
Other Name:5-amino-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-[(1R,S)-(trifluoromethyl)sulfinyl]-1H-pyrazole-3-carbonitrile
CAS Number: [ 120068-37-3 ]
Molecular Formula: C12H4Cl2F6N4OS
Fipronil is a broad spectrum insecticide that disrupts the insect central nervous system by blocking the passage of chloride ions through the GABA receptor and glutamate-gated chloride channels (GluCl), components of the central nervous system. This causes hyperexcitation of contaminated insects' nerves and muscles. Insect specificity of fipronil may come from a better efficacy on GABA receptor but also on the fact that GluCl does not exist in mammals.
Fipronil is a broad use insecticide that belongs to the phenylpyrazole chemical family. Fipronil is used to control ants, beetles, cockroaches, fleas, ticks, termites, mole crickets, thrips, rootworms, weevils, and other insects. Fipronil is a white powder with a moldy odor.
Fipronil is used in a wide variety of pesticide products, including granular products for grass, gel baits, spot-on pet care products, liquid termite control products, and products for agriculture. There are more than 50 registered products that contain fipronil. Fipronil kills insects when they eat it or come in contact with it. Fipronil works by disrupting the normal function of the central nervous system in insects. Fipronil is more toxic to insects than people and pets because it is more likely to bind to insect nerve endings.
APPLICATIONS
Biochemistry
Insecticide which acts as a potent blocker of the GABA-regulated chloride channel. Insects resistant or tolerant to pyrethroid, cyclodiene, organophosphorus and/or carbamate insecticides are susceptible to fipronil.
Mode of action
Broad-spectrum insecticide, toxic by contact and ingestion. Moderately systemic and, in some crops, can be used to control insects when applied as a soil or seed treatment. Good to excellent residual control following foliar application.
Uses Control of multiple species of thrips on a broad range of crops by foliar, soil or seed treatment. Control of corn rootworm, wireworms and termites by soil treatment in maize. Control of boll weevil and plant bugs on cotton, diamond-back moth on crucifers, Colorado potato beetle on potatoes by foliar application. Control of stem borers, leaf miners, planthoppers, leaf folder/rollers and weevils in rice. Foliar application rates range from 10-80 g/ha; soil treatment rates 100-200 g/ha.
