Fenvalerate

Topic editor

[This article has been tagged for development.]

Fenvalerate is a non-leaching non-volatile pyrethroid insecticide, similar to Permethrin though much more degradable (#Cornell University). It is moderately toxic to mammals and is composed of four isomers that all have different insecticidal activities (#INCHEM). It is not banned, restricted, or canceled in any countries (#PAN).

    Just the facts


    Physical Information

    Name: Fenvelerate

    Use: insecticide

    Source: synthetic chemistry

    Recommended daily intake: none

    Absorption: dermal, inhalation, ingestion

    Toxicity/symptoms: moderately toxic to mammals

    Regulatory facts: no canceled in any country

    Chemical Structure


Chemical Description


Fenvalerate is a yellow-brown viscous liquid that is practically soluble in water (#INCHEM). It is stable to moderate heat and light and is rapidly hydrolysed in basic environments (above pH 8) (#INCHEM).

Uses


Fenvalerate is a contact and sytemic pyrethroid insecticide that is used to control insects on numerous leaves and fruits, on feed and cotton production, to control flies and ticks for livestock and in stables (#INCHEM).

Health Effects


Fenvalerate is moderately toxic to mammals. Based on fenvalerate similarities with Deltamethrin, toxicity is probably due to effects on both peripheral and central nervous system caused by interference with sodium ion permeability in stimulated nerve membranes (#INCHEM).

Acute Symptoms
* burning sensation
* cough
* dizziness
* headache
* nausea
* redness
* tingling
* itching
* abdominal pain
* convulsions
* vomiting

Chronic Toxicity

Environmental Effects


Fenvalerate is a non-leaching non-volatile chemical. The half-life of fenvalerate varies from 6 weeks to 60 days depending upon the soil type (#Cornell University).

It is highly toxic to honey bees and fish (#INCHEM).

Regulation


Fenvalerate is not canceled, restricted, or banned in any country (#PAN).
