説明
Bifenthrin 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.

使用
Bifenthrin controls foliar insect pests and some mites on a range of
crops including cereals, citrus, cotton, fruit and vegetables.

定義
ChEBI: 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.

健康ハザード
Bifenthrin 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

代謝経路
When 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.
-
貯蔵
Bifenthrin 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

不和合性
May 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.

廃棄物の処理
Incineration 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.
