- 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.
- 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
- 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
- Average domestic
usage of trichlorfon is about one million pounds active ingredient (a.i.)
- 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
- 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.
- 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.
