Bifenthrin Technical

Type: Synthetic Pyrethroid Insecticide

Chemical Category

  • Common Name: Bifenthrin
  • IUPAC Name: (2-methyl-[1,1′-biphenyl]-3-yl)methyl-(Z)-(1RS,3RS)-3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2-dimethylcyclopropanecarboxylate
  • Chemical Formula: C₂₃H₂₂ClF₃O₂
  • CAS No.: 82657-04-3
  • Chemical Family: Synthetic Pyrethroid Insecticide
  • Type: Contact and stomach poison; non-systemic insecticide and acaricide

Mode of Action

  • Bifenthrin acts on the nervous system of insects.
  • It blocks sodium channels in nerve membranes, preventing normal nerve signal transmission.
  • This leads to paralysis and death of the insect.
  • Exhibits strong contact, residual, and repellent action with very low vapor pressure (long-lasting effect).

Applications

  • Used extensively in agriculture, public health, urban pest control, and termite management.
  • Controls a wide range of chewing and sucking insects on crops such as:
  • Cotton, Paddy, Maize, Soybean, Sugarcane, Groundnut, Fruits & Vegetables (tomato, cabbage, okra, brinjal, etc.) Tea, coffee, and ornamental crops

Also used for

  • Termite control in wood and buildings
  • Mosquito and ant control in households and public health
  • Weeds Controlled
  • (It does not control weeds but targets insects, mites, and termites.)

Technical Overview

  • Viscous liquid or crystalline solid
  • 68–70°C
  • Stable in neutral to slightly acidic conditions
  • Extremely low – provides long residual activity

 Main Uses

  • Agricultural: Control of bollworms, leaf folders, aphids, jassids, thrips, and stem borers.
  • Public Health: Effective against mosquitoes, flies, cockroaches, and ants.
  • Termiticide: Used for soil treatment and wood preservation against termites.
  • Veterinary/Animal Use: For ectoparasite control in livestock (in specific formulations).

Storage and Stability

  • Store in a cool, dry, well-ventilated area.
  • Keep away from heat, sunlight, and open flames.
  • Avoid contact with alkaline materials or oxidizing agents.
  • Store in tightly sealed containers.
  • Stable for minimum 2 years under normal storage conditions.
  • Decomposes under strong UV light or extreme heat.
  • Resistant to hydrolysis in neutral and acidic media; unstable in alkaline conditions.
