Beschreibung
Hexaflumuron is a benzoylphenyl urea-type insecticide and is the common name for N-(((3,5- dichloro-4-(1,1,2,2-tetrafluoro-ethoxy)phenyl)amino)carbonyl)-2,6-difluorobenzamide. It the active ingredient in several termite control products registered to Dow AgroSciences LLC, a wholly owned subsidiary of The Dow Chemical Company. Hexaflumuron was the first active ingredient to be registered with the U.S. Environmental Protection Agency (EPA) as a reduced-risk pesticide. A reduced-risk pesticide is one that the EPA believes has low impact on human health, low toxicity to non-target organisms, and low potential for groundwater contamination. Hexaflumuron’s mode of action is to inhibit chitin synthesis. Termites produce chitin to form or maintain an exoskeleton.
Hexaflumuron is an odorless white solid that is formulated into low-concentration solid briquettes that are contained within tamper-resistant bait stations. Formulated hexaflumuron briquettes contain about 0.5% of the active ingredient, with the balance comprised almost entirely of cellulose.
Hexaflumuron formulations have been marketed under the trade names RECRUIT® AG termite bait, SHATTER*termite bait, SENTRI*TECH, RECRUTE® Pro, Hex-Pro(TM) Termite Baiting System, Sentricon(TM) IG Termite Bait, Sentricon(TM) AG Termite Bait, Sentricon® Termite Colony Elimination System.
Chemische Eigenschaften
White solid or powder. The commercial product
may be an emulsifiable concentrate.
Verwenden
Hexaflumuron is an benzoylphenylurea based chitin synthesis inhibitor used against Ephestia figulilella.
Definition
ChEBI: An N-acylurea that is urea in which a hydrogen attached to one of the nitrogens is replaced by a 2,6-difluorobenzoyl group, while a hycrogen attached to the other nitorgen is replaced by a 3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)phenyl
group.
mögliche Exposition
Hexaflumuron is a benzoyl urea insecti cide, termiticide and insect growth regulator (IGR) that inhi bits an insect’s growth through chitin synthesis, which
termites need to form an exoskeleton. It is used to impregnate
termite bait. Worldwide, there are more than 20 suppliers/
manufacturers; most are in the United States Not currently
registered for agricultural use in some EU countries.
Stoffwechselwegen
Although there is limited dormation on the metabolism of hexaflumuron
in the open literature, there is a useful summary provided by
Dow Agrosciences (Anon). Metabolic pathways are shown in Scheme 1.
Versand/Shipping

solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous haz ardous material, Technical Name Required.
Inkompatibilitäten
Decomposes in temperatures above
275 C. Irritating or toxic fumes or gases in a fire
Waste disposal
Do not discharge into drains
or sewers. Dispose of waste material as hazardous waste
using a licensed disposal contractor to an approved land fill. Consult with environmental regulatory agencies for
guidance on acceptable disposal practices. Incineration
with effluent gas scrubbing is recommended. Containers
must be disposed of properly by following package label
directions or by contacting your local or federal environmental control agency, or by contacting your
regional EPA office.
