Trichlorfon 90% SP

Trichlorfon is a powerful, fast-acting organophosphorus insecticide known for its broad-spectrum control and low toxicity. It works primarily through stomach poisoning, with additional contact and osmotic action, making it highly effective for eliminating pests across agriculture, livestock, aquaculture, and public health environments.

From grub control in lawns to external parasite management in livestock, Trichlorfon delivers reliable pest control with minimal residue—ideal for integrated pest management (IPM) programs.

Key Benefits of Trichlorfon

🌾 Broad-Spectrum Pest Control

  • Controls chewing pests, underground insects, livestock parasites, and sanitary pests (flies, mosquitoes, fleas)

  • Effective against grubs, beetle larvae, nematodes, and more

🐄 Versatile Across Sectors

  • Suitable for use on rice, vegetables, fruit trees

  • Effective for livestock parasite control (lice, ticks, scabies)

  • Used in aquaculture to prevent fish diseases caused by parasites

Fast-Acting with Low Residue

  • Delivers rapid pest knockdown while leaving minimal residue

  • Excellent fit for residue-sensitive markets and IPM practices

How Trichlorfon Works

Trichlorfon targets the insect nervous system by inhibiting cholinesterase, leading to overstimulation, paralysis, and death. Its multi-action mode ensures broad efficacy:

  • Stomach Poisoning: Insects ingest treated plants

  • Contact Action: Direct exposure causes instant kill

  • Osmotic Activity: Penetrates plant tissues for systemic control

Target Pests

  • Lawn Grubs

  • Beetle Larvae

  • Cabbage Worms, Leafrollers

  • Soil-Borne Insects

  • External Parasites (Lice, Ticks, Scabies)

  • Fish Parasites (Trematodes, Nematodes, Cladocerans)

Application Guidelines

Formulation Use Case Target Pests Dosage Method
30% EC Rice, Vegetables, Fruit Trees Chewing pests, leafrollers 30 L/mu Foliar spray
80% SP Rice, Wheat, Vegetables Cabbage worm, bridgeworm 30 L/mu Foliar spray
90% SP Fruit Trees Underground pests 30 L/mu Soil incorporation or spray
97% TC Livestock Lice, ticks, flies 1–3% solution Direct animal spray

Timing: Apply during the early larval stages for best results.
Aquaculture: Monitor pH levels to avoid degradation into dichlorvos in alkaline water.

Mixed Formulations for Enhanced Performance

🔸 Trichlorfon 30% + Profenofos 10% EC

Enhanced contact and systemic action. Suitable for cotton and vegetable pests, especially chewing insects and mites.

🔸 Trichlorfon 20% + Dimethoate 20% EC

Ideal for controlling both sucking and chewing pests on rice, cotton, and wheat. Dimethoate strengthens systemic protection.
