Methoxyfenozide 甲氧虫酰肼
Introduction: 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.

Usage: Methoxyfenozide was developed by Dow AgroSciences. It is an insecticide used to control various insects including moths and butterflies.
Application: Biochemistry Second generation ecdysone agonist. Causes cessation of feeding and premature lethal moult. Mode of action Active primarily by ingestion, also with contact and ovicidal activity. Does not have translaminar or phloem-systemic properties. Uses Control of lepidopterous larvae, in vines, tree fruits, vegetables and row crops, at 20 - 300 g/ha.
