Meothrin Insecticide: Fenpropathrin Composition and Uses

Meothrin is a broad-spectrum synthetic pyrethroid insecticide and acaricide manufactured by Sumitomo Chemical India, formulated with Fenpropathrin 30% EC. It acts on the insect nervous system by disrupting voltage-gated sodium channels (IRAC Group 3A), delivering rapid contact knock-down, repellent action, and stomach toxicity. Meothrin is uniquely suited for controlling both chewing caterpillars and phytophagous mites simultaneously in cotton, tea, chilli, and vegetable crops.

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.

Common questions

What is the technical active chemical in Meothrin?

Meothrin contains Fenpropathrin 30% EC, a broad-spectrum synthetic pyrethroid with both insecticidal and acaricidal properties.

Can Meothrin be used to control spider mites?

Yes, unlike standard synthetic pyrethroids that can flare mite populations, Fenpropathrin provides direct contact control of agricultural mites.

What personal protective equipment is recommended during Meothrin application?

Applicators must wear protective masks, rubber gloves, safety goggles, and full-length protective clothing during mixing and spraying.
