Bifenthrin Usage And Synthesis
- DescriptionBifenthrin is synthetic pyrethroid insecticide with biochemical origins in the natural insecticide pyrethrum. It is a waxy solid with a color ranging from an off-white to a pale tan, and with a slightly sweet odor. It is almost insoluble in water. Bifenthrin is used for the control of borers and termites in timber, insect pests in agricultural crops (bananas, apples, pears, ornamentals) and turf, as well as for general pest control (spiders, ants, fleas, flies, mosquitoes). Due to its high toxicity to aquatic organisms, it is listed as a restricted use pesticide. It has a very low solubility in water and tends to bind to soil, which minimizes runoff into water sources. It is marketed as Talstar, Bifenthrine, Brigade, Capture, Torant, Zipak, FMC 54800, and OMS3024.

- DescriptionBifenthrin is a synthetic pyrethroid insecticide/miticide/acaricide. Bifenthrin is off-white to pale tan waxy solid granules with a faint, musty odour and a slightly sweet smell. Bifenthrin is soluble in methylene chloride, acetone, chloroform, ether, and toluene and slightly soluble in heptane and methanol. It is slightly combustible and support combustion at elevated temperatures. Thermal decomposition and burning may form toxic byproducts such as carbon monoxide, carbon dioxide, hydrogen chloride, and hydrogen fluoride. Bifenthrin treatment affects the nervous system and causes paralysis in insects.

- Chemical PropertiesOff white to pale tan waxy substance. Faint, sweet odor.
- UsesThird generation synthetic pyrethroid. Insecticide, acaricide.
- UsesBifenthrin controls foliar insect pests and some mites on a range of crops including cereals, citrus, cotton, fruit and vegetables.
- UsesInsecticide, acaricide.
- DefinitionChEBI: A carboxylic ester obtained by formal condensation of cis-3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2-dimethylcyclopropanecarboxylic acid and [(2-methyl-1,1'-biphenyl)-3-yl]methanol.
- Health HazardBifenthrin is moderately toxic to species of mammals when ingested. Exposures to large doses of bifenthrin cause poisoning with symptoms that include, but are not limited to, incoordination, tremor, salivation, vomiting, diarrhea, and irritability to sound and touch. Exposures to bifenthrin through skin absorption and/or inhalation of dust cause adverse health effects. On contact with bifenthrin, occupational workers develop adverse health effects that include skin sensations, rashes, numbness, and a burning and tingling type of effect. As a pyrethroid poison, bifenthrin disturbs the electrical impulses in nerves, over-stimulating nerve cells, causing tremors and eventually causing paralysis. The skin-related health effects were found to be reversible and subside after a brief period of time and stoppage of further exposures to bifenthrin. Although bifenthrin causes no infl ammation or irritation on human skin, it can cause a tingling sensation that lasts about 12 h. Bifenthrin has caused no symptoms of irritation to rabbits’ eyes. The US EPA has classifi ed bifenthrin as toxicity class II, meaning moderately toxic
- Agricultural UsesInsecticide, Acaricide: A broad-spectrum insecticide. Registered to control cone worms, seed bugs, seed worms and other insects and mites on rangeland, forests and right-of-ways. It is also used to control household and lawn pests. A U.S. EPA restricted Use Pesticide (RUP).
- Trade nameBIFLEX®; BISTAR®; BRIGADE®; CAPTURE® Bifenthrin; DISCIPLINE®; DOUBLE THREAT®; EMPOWER®; FMC® 54800; FMC® 58000; TALSTAR®; TALSTAR LAWN & TREE®; TORANT®; ZIPAK®
- Potential ExposureA broad spectrum pyrethroid secticide/ acaricide used to control cone worms, seed bugs, seed worms and other insects and mites in forests, on rangeland, and right-of-ways. It is also used to control household and lawn pests. A United States Environmental Protection Agency Restricted Use Pesticide (RUP).
- Metabolic pathwayWhen mites are administered 14C-bifenthrin either by injection or by contact, bifenthrin is efficiently metabolized by the mites and the metabolites identified arise from the combination of ester cleavage, oxidation, and conjugation reactions and are the 4'-hydroxy derivative of the ester, the primary ester cleavage products, the acid, and its 4'-hydroxy derivative from the alcohol moiety, as well as several unidentified metabolites.
- storageBifenthrin should be kept stored in a cool, dry, well-ventilated place away from heat, open flame or hot surfaces. It should only be stored in its original containers and should not be contaminated with other pesticides, fertilizers, water, food, or feed by storage or disposal
- ShippingUN2588 Pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1—Poisonous materials, Technical Name Required. UN3349 Pyrethroid pesticide, solid toxic, Hazard Class: 6.1; Labels: 6.1—Poisonous material.
- DegradationBifenthrin is stable for 21 days in the pH range 5-9 at 21°C but it is labile at higher pH. It has a DT50 of 225 days in natural daylight and can therefore be regarded as relatively photochemically stable (PSD).
- IncompatibilitiesMay react violently with strong oxidizers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders or dust. Incompatible with silver compounds, lime, and ordinary soaps. Mixture with some silver compounds forms explosive salts of silver oxalate.
- Waste DisposalIncineration would be an effective disposal procedure where permitted. If an efficient incinerator is not available, the product should be mixed with large amounts of combustible material and contact with the smoke should be avoided. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers.
