Information @ Glance


  • Trichlorfon [dimethyl (2,2,2-trichloro-1-hydroxyethyl) phosphonate] is an organophosphorus insecticide, which acts as an acetylcholinesterase inhibitor.
  • Trichlorfon was first registered as a pesticide in the U.S. in 1955 by USDA. The Agency issued a Registration Standard for trichlorfon in June 1984.
  • Trichlorfon is produced and used in dust, emulsifiable concentrate, granular, fly bait, and soluble powder formulations and the concentration of trichlorfon in the product ranges from around 40-98%.
  • Some Trade names for Trichlorfon are Anthon, Bovinos, Briten, Chlorophos, Ciclosom, Dylox, Dipterex, Ditrifon, Dylox, Dyrex, Leivasom,Trichlorophon, Trinex,  and Vermicide Bayer 2349.When this material is used as a drug, it is called metrifonate or metriphonate.

Method of Application

  • Turf, ornamentals and nurseries: mechanical and hand-held sprayers, spreaders (for granular formulations), aerial equipment, irrigation systems.
  • Indoor and outdoor treatments: soluble powders in water through hand-held sprayers; dry baits can be “sprinkled” out of a cup or spoon or put onto cardboard or plastic or applied as a mound treatment for ants; bait mixed with water and “sprinkled” out of a cup or watering can.


  • Trichlorfon is seldom used in production of maize, sweetcorn, brassicas and tomatoes.
  • Trichlorfon is  used overseas on cattle as a pour-on treatment.
  • An insecticide, trichlorfon is used on golf course turf, home lawns, non-food contact areas of food and meat processing plants, ornamental shrubs and plants, and ornamental and bait fish ponds to control insects such as lepidopteran larvae (caterpillars), white grubs, mole crickets, cattle lice, sod webworms, leaf miners, stink bugs, flies, ants, cockroaches, earwigs, crickets, diving beetle, water scavenger beetle, water boatman backswimmer, water scorpions, giant water bugs and pillbugs.


  • Average domestic usage of trichlorfon is about one million pounds active ingredient (a.i.) per year.
  • In terms of pounds a.i., total usage is allocated mainly to lawn care operators (74%) and golf courses (18%). However, on
    average, less than 2% of all turf sites are treated with trichlorfon.
  • Other sites with small usage include landscaping, institutional turf, turf farms, nursery/greenhouse, livestock and general farm use. Application rates per acre on these sites are generally less than 7 pounds a.i. per acre.
  • Outcome Scenario, the continued availability of trichlorfon with additional management controls applied, is proposed for a number of the existing veterinary medicine uses.
  • Trichlorfon has been used in New Zealand for over 30 years with no reported incidents of human or animal poisoning.
