Methoxyfenozide, a substituted dibenzoylhydrazine, is an insecticide that functions by accelerating the moulting process. It acts as an ecdysone agonist or ecdysonoid, substituting for the natural insect moulting hormone, 20-hydroxyecdysone. Methoxyfenozide is active on all feeding larval stages of the target Lepidoptera.
It is used to control pests including codling moth, lesser apple worm, oriental fruit moth, leafrollers, cabbage looper, cotton bollworm, armyworm, and bud moths. It could be applied to leafy vegetables, fresh herbs, lettuce, salads, herbs, brassicas, cotton, pome fruit, grapes, sweetcorn, maize, peppers, and aubergines.

White crystalline solid or powder.
The industrial synthesis of methoxyfenozide begins with the preparation of two key intermediates: 3,5-dimethylbenzoyl chloride and 3-methoxy-o-toluic acid hydrazide. The hydrazide is synthesised by reacting the corresponding acid chloride with hydrazine hydrate under controlled temperature and pH conditions. This intermediate is then acylated with the dimethylbenzoyl chloride in the presence of a base such as triethylamine or pyridine, forming the diacylhydrazine backbone. The reaction is typically carried out in organic solvents like dichloromethane or acetonitrile, and the product is purified through crystallisation or solvent extraction to ensure high purity and yield.
ChEBI: A carbohydrazide that is hydrazine in which the amino hydrogens have been replaced by 3-methoxy-2-methylbenzoyl, 3,5-dimethylbenzoyl, and tert-butyl groups respectively.
Low toxicity by ingestion, inhalation, and
skin contact.
Insecticide: Methoxyfenozide prevents insects from molting, or
shedding their exoskeleton in order to grow, e. g., caterpillars
and lychee webworms.
A moulting accelerator that is an agonist of the hormone 20-hydroxyecdysone. Ecdysone receptor agonist.
