Active Ingredient Profile and Neurotoxic Action
Fenpropathrin is a potent synthetic pyrethroid containing a cyano group in an emulsifiable concentrate formulation.
It acts on voltage-gated sodium channels in insect and mite nerve membranes, causing prolonged nerve depolarization, rapid tremors, feeding cessation, and death.
- Formulation: 10 percent Emulsifiable Concentrate (EC)
- Dual action: Combines effective insecticidal activity with strong acaricidal mite suppression
- Repellent effect: Anti-feeding and repellency properties reduce pest oviposition on treated foliage
Target Pests and Crop Applications
Fenpropathrin is registered for crops where sucking pests and foliar caterpillars attack simultaneously.
It is especially valued in cotton, tea, and chili production for managing difficult red spider mites and whitefly nymphs.
- Cotton: Controls pink bollworm, spotted bollworm, whitefly, and red spider mites
- Tea: Suppresses red spider mites, purple mites, and tea mosquito bug
- Vegetables and chilies: Controls yellow mites and foliage-feeding lepidopteran larvae
Application Guidelines and Safety Protocols
Thorough canopy penetration is critical because mites typically congregate on the undersides of mature leaves.
Applicators must observe mandatory safety rules, avoid spraying during hot midday hours, and protect beneficial pollinators.
Rotate with non-pyrethroid acaricides to prevent resistant mite populations from emerging.
- Nozzle type: Use hollow cone nozzles to generate fine droplets covering lower leaf surfaces
- Pollinator safety: Highly toxic to bees; avoid spraying during crop flowering hours
- Personal protection: Wear protective rubber gloves, mask, and goggles during handling and spraying

Common questions
What makes Fenpropathrin different from standard synthetic pyrethroids?
Unlike most synthetic pyrethroids which only control insects, Fenpropathrin delivers strong dual insecticidal and acaricidal (mite-killing) efficacy.
Does Fenpropathrin control red spider mites in tea and cotton?
Yes, Fenpropathrin is registered for controlling red spider mites, providing fast contact knockdown and repellency.
Is Fenpropathrin systemic inside plant tissues?
No, Fenpropathrin works through contact and stomach action, requiring thorough spray coverage of all plant surfaces.
