Химические свойства
Pale Yellow Low Melting Solid
Использование
Tefluthrin is a pyrethroid based insecticide. Tefluthrin is used in the control of a broad range of soil pests, including members of the Coleoptera, Lepidoptera, and Diptera.
Определение
ChEBI: A cyclopropanecarboxylate ester resulting from the formal condensation of the carboxy group of 3-[(1Z)-2-chloro-3,3,3-trifluoroprop-1-en-1-yl]-2,2-dimethylcyclopropanecarboxylic acid with the hydroxy group of 2,3,5,6-tetrafluoro-4-methylbe
zyl alcohol.
Сельскохозяйственное использование
Insecticide, Miticide: A U.S. EPA restricted use Pesticide (RUP).
Registered in the U.S. for use on corn. Elsewhere it is registered
for use on a variety of crops, e.g., peanuts, sweet
potato, sugarcane, cabbage, radish, Brussels sprouts, and
strawberries. Registered for use in EU countries.

Фармаколо?гия
The commercialized
compound, tefluthrin, was recommended to
control soil-inhabiting pests (28). The most salient feature
of the compound, which justifies its use exclusively for better
performance of tefluthrin as a soil insecticide compared
with cyhalothrin, is its approximately four orders ofmagnitude
higher vapor pressure (V.P. = 8.4 vs. 0.001 mPa; see
Table 6). Beside the quick insecticidal action attributed to
fast penetration, tefluthrin also displays toxic symptoms
at its sublethal dose, which could play an important role
in field performance (179). The most active configuration
of tefluthrin, (Z)(1RS)-cis-isomer mixture, is the optically
active (Z)(1R)-cis-isomer.
Метаболический путь
When a goat is dosed with 14C-tefluthrin orally,
extensive metabolism occurs in the goat by ester
cleavage and oxidation at a variety of positions on the
molecules. Low radioactive residues are detected in
the milk, fat, and muscle, with tefluthrin as the largest
individual component of the residue. Higher residues
are present in the kidney and liver, and only a small
percentage of this residue is due to tefluthrin. The
remainder in the kidney and liver is a complex mixture
of metabolites. In total, eight metabolites are identified
in the feces and urine as well as other tissues such as
fat, muscle, kidney, and liver.
