Introduction of CAS:86479-06-3 | Hexaflumuron
Hexaflumuron is a termiticide, an insecticide specifically used on termites, first registered in the United States in 1994 . It is a benzoyl urea insecticide and an insect growth regulator (IGR) that inhibits an insect's growth through chitin synthesis, which termites need to form an exoskeleton .

Research Application of CAS:86479-06-3 | Hexaflumuron
Pest Control in Brassicaceous Vegetables
Hexaflumuron has been globally registered for over two decades to control pests in brassicaceous vegetables . It's particularly effective in controlling pests in turnip and cauliflower . Field trials have been carried out at six representative experimental sites to study the dissipation behaviors and terminal residues of hexaflumuron in these vegetables .
Residue Analysis
The residual amounts of hexaflumuron were extracted using a modified QuEChERS and analyzed with liquid chromatography-tandem mass spectrometry (HPLC–MS/MS) . The half-lives of hexaflumuron ranged from 0.686 to 1.35 and 2.41 to 6.71 days in cauliflower and turnip leaves, respectively .
Risk Evaluation
The chronic dietary risk of hexaflumuron in the preharvest interval of 7 days was lower than 100% and much higher than 0.01%, indicating acceptable but nonnegligible health hazards for Chinese consumers . Therefore, MRL values of hexaflumuron were proposed as 2, 0.8, and 10 mg/kg in cauliflower, turnip tubers, and turnip leaves, respectively .
