1. Ammonium sulfamate
Ammonium sulfamate (British spelling Ammonium
sulphamate) is a white crystalline solid, readily solu-
ble in water. It is commonly used as a broad spectrum
herbicide, with additional uses as a compost accelerator,
flame retardant and in industrial processes.
1 Manufacture and distribution
It is a salt formed from ammonia and sulfamic acid.
Ammonium sulfamate is distributed under the follow-
ing tradenames, which are principally herbicidal product
names: Amicide, Amidosulfate, Ammate, Amcide, Am-
mate X-NI, AMS, Fyran 206k, Ikurin, Sulfamate, AMS
and Root-Out.
2 Uses
2.1 Herbicide
Ammonium sulfamate is considered to be particularly
useful in controlling tough woody weeds, tree stumps and
brambles.
Ammonium sulfamate has been successfully used in sev-
eral major UK projects by organisations like the British
Trust for Conservation Volunteers, English Heritage, the
National Trust, and various railway, canal and waterways
authorities.
Several years ago the Henry Doubleday Research Associ-
ation (HDRA) (known as Garden Organic), published an
article on ammonium sulfamate after a successful set of
herbicide trials. Though not approved for use by organic
growers it does provide an option when alternatives have
failed.
The following problem weeds / plants can be con-
trolled: Japanese Knotweed (Fallopia japonica var
japonica), Marestail / Horsetail (Equisetum), Ground-
elder (Aegopodium podagraria), Rhododendron pon-
ticum, Brambles, Brushwood, Ivy (Hedera species),
Senecio/Ragwort, Honey fungus (Armillaria), and felled
tree stumps and most other tough woody specimens.
2.2 Compost accelerator
Ammonium sulfamate is used as a compost accelerator.
It is especially effective in breaking down the tougher and
woodier weeds put onto the compost heap.
2.3 Flame retardant
Ammonium sulfamate (like other ammonium salts, e.g.
Ammonium dihydrogen phosphate, Ammonium sulfate)
is a useful flame retardant.[4]
These salt based flame re-
tardants offer advantages over other metal/mineral-based
flame retardants in that they are water processable. Their
relatively low decomposition temperature makes them
suitable for flame retarding cellulose based materials (pa-
per/wood). Ammonium sulfamate (like Ammonium di-
hydrogen phosphate) is sometimes used in conjunction
with Magnesium sulfate or Ammonium sulfate (in ratios
of approximately 2:1) for enhanced flame retardant prop-
erties.
2.4 Other uses
Within industry ammonium sulfamate is used as a flame
retardant, a plasticiser and in electro-plating. Within the
laboratory it is used as a reagent.
3 Safety
Ammonium sulfamate is considered to be slightly toxic
to humans and animals, making it appropriate for ama-
teur home garden, professional and forestry uses.[5]
It is
generally accepted to be safe for use on plots of land that
will be used for growing fruit and vegetables intended for
consumption.
In the United States, the Occupational Safety and Health
Administration has set a permissible exposure limit at 15
mg/m3
over an eight-hour time-weighted average, while
the National Institute for Occupational Safety and Health
recommends exposures no greater than 10 mg/m3
over an
eight-hour time-weighted average.[6]
These occupational
exposure limits are protective values, given the IDLH
concentration is set at 1500 mg/m3
.[7]
It is also considered to be environmentally friendly due to
its degradation to non-harmful residues.
3.1 European Union licensing
The pesticides review by the European Union led to her-
bicides containing ammonium sulfamate becoming unli-

censed, and therefore effectively banned, from 2008.[8]
This situation arose as the Irish Rapporteur refused to re-
view the data supplied unless it contained details of ani-
mal testing on dogs. As there was already substantial ani-
mal data within the package supplied the data pack holder
felt further tests without substantiation would cause un-
necessary animal suffering. Its licence was not withdrawn
on grounds of safety or efficacy.
Its availability and use as a compost accelerator is unaf-
fected by the EU’s pesticide legislation.
