Tefluthrin (Biphenthrin, (1S,3S)-rel-2,3,5,6-Tetrafluoro-4-methylbenzyl 3-((Z)-2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropanecarboxylate, CAS#79538-32-2) is an organic compound. It is classified as a pyrethroid, meaning that in terms of chemical structure, it resembles the naturally occurring insecticide pyrethrin. It was designed to be effective against soil pests. With an LD50 for rats of at 29 mg/kg, Tefluthrin is one of the most toxic pyrethroids.
On a large scale bifenthrin is often used against red imported fire ants. It is also effective against aphids, worms, ants, gnats, moths, beetles, grasshoppers, mites, midges, spiders, ticks, yellow jackets, maggots, thrips, caterpillars, flies and fleas. It is mostly used in orchards, nurseries and homes. In the agricultural sector, it is used in great amounts on certain crops, like corn. About 70% of all hops and raspberries cultured in the United States are treated with bifenthrin. Bifenthrin is very toxic to many insects, fish and other aquatic animals. It is only slightly toxic to mammals and not at all toxic to plants. Even though it does not have a large toxicological risk towards mammals or birds, bifenthrin is able to accumulate in food, and therefore might be dangerous to mammals or birds in some scenarios.
