Flufenoxuron
Flufenoxuron is an insecticide that belongs to the benzoylurea chitin [synthesis inhibitor] group, which also includes diflubenzuron, triflumuron, and lufenuron.
Application
Flufenoxuron is used as an insecticide primarily on citrus plants, cotton, grape, tea and soybean.
Due to the development of resistance in some cases, the effects of chlorfluazuron and flufenoxuron on selected developmental and reproductive parameters of the agrotis ipsilon were examined in a study. It was found that chlorfluazuron and flufenoxuron can accelerate vitellogenesis in the ypsilon owl.
Synthesis
The multi-step synthesis of flufenoxuron is described in the following reaction sequence:
A plant protection product containing the active ingredient flufenoxuron is marketed under the trade name Cascade.
Authorization
No plant protection products containing this active ingredient are authorized in Germany or in the EU.
Properties
Flufenoxuron is a white crystalline powder. It has low solubility in water, is not flammable, and is not an oxidizer.
Flufenoxuron toxicity to humans and other mammals is low, but it has a potentially high bioaccumulation in fish despite its low water solubility.
