Active ingredient and dual insecticidal-acaricidal action
Fenpropathrin is distinguished among synthetic pyrethroids by its potent dual activity against both insect larvae and mite complexes.
- Neurotoxic mode of action: Prolongs opening of voltage-dependent sodium channels in nerve axons, inducing rapid tremors and fatal paralysis.
- True acaricidal property: Provides lethal contact knockdown against adult mites, nymphs, and hatching stages.
- Strong repellent property: Discourages insect pests from settling, laying eggs, or feeding on treated foliage.
- Formulated as an emulsifiable concentrate (30% EC) providing uniform droplet coverage on waxy plant leaves.
Target crops and registered pest management
Meothrin is registered under CIBRC guidelines for managing complex pest infestations across key cash and plantation crops.
- Cotton: Simultaneous control of pink bollworm, spotted bollworm, American bollworm, and red spider mites.
- Tea: Control of red spider mites, pink mites, and tea mosquito bug.
- Chilli: Suppression of yellow mites and fruit borer complexes.
- Vegetables: Management of leaf-eating caterpillars and spider mites during vegetative growth.
Safe application and resistance management
Always adhere to the approved label rate and follow prescribed pre-harvest intervals. Apply using knapsack or power sprayers equipped with hollow cone nozzles for thorough canopy coverage. Wear full protective clothing, rubber gloves, and safety goggles. To avoid pyrethroid resistance, rotate Meothrin with insecticides from different IRAC groups such as avermectins or diamides.
