Fenpropathrin

<p>Fenpropathrin, or fenopropathrin, is a widely used <a href="/facts/Pyrethroid/Lf1N0STQ">pyrethroid</a> <a href="/facts/Insecticide/1xYL3MSD">insecticide</a> in <a href="/facts/Agriculture/TGztqzJs">agriculture</a> and household. Fenpropathrin is an ingestion and contact synthetic pyrethroid. Its mode of action is similar to other natural (<a href="/facts/Pyrethrum/mdyKjAu9">pyrethrum</a>) and <a href="/facts/Synthetic_pyrethroid/Lf1N0STQ">synthetic pyrethroids</a> where in they interfere with the kinetics of voltage gated sodium channels causing paralysis and death of the pest. Fenpropathrin was the first of the light-stable synthetic pyrethroids to be synthesized in 1971, but it was not commercialized until 1980. Like other pyrethroids with an α-cyano group, fenpropathrin also belongs to the termed type II <a href="/facts/Pyrethroid/Lf1N0STQ">pyrethroids</a> (e.g. <a href="/facts/Cyfluthrin/J3DCuzwu">cyfluthrin</a>, <a href="/facts/Cyhalothrin/9D0D6k00">cyhalothrin</a>, <a href="/facts/Cypermethrin/vwCnuzBh">cypermethrin</a>, <a href="/facts/Deltamethrin/mQGPkAsg">deltamethrin</a> and <a href="/facts/Esfenvalerate/CUuVGS3J">esfenvalerate</a>). Type II pyrethroids are a more potent toxicant than type I in depolarizing insect nerves. Application rates of fenpropathrin in agriculture according to US environmental protection agency (EPA) varies by crop but is not to exceed 0.4 lb ai/<a href="https://www3.epa.gov/pesticides/chem_search/ppls/059639-00035-20170919.pdf">acre</a>.
