Chemische Eigenschaften
Bendiocarb is an odorless, white crystalline solid. Some of the formulations of bendiocarb
are classii ed as a GUP, while Turcam and its 2.5 G formulation have been classii ed as
a RUP. Bendiocarb is stable under normal temperatures and pressures, but should not
be mixed with alkaline preparations. Thermal decomposition products may include toxic
oxides of nitrogen. It is non-corrosive. Bendiocarb as a carbamate insecticide is effective
against a wide range of insects that cause nuisance and act as disease vectors. It is used to
control mosquitoes, l ies, wasps, ants, l eas, cockroaches, silveri sh, ticks, and other pests
in homes, industrial plants, and food storage sites. In agriculture, it is used against a vari-
ety of insects, especially those in the soil. Bendiocarb is also used as a seed treatment on
sugar beets and maize and against snails and slugs. Pesticides containing bendiocarb are
formulated as dusts, granules, ultra-low volume sprays, and as wettable powders
Verwenden
Bendiocarb is a benzodioxolyl carbamate derivative. Bendiocarb is commonly used as an insecticide in agriculture against a wide range of pests and insects. Bendiocarb is one of the insecticides recomm
ended by world health organization (WHO) for use in malaria control.
Allgemeine Beschreibung
White solid. Melting point 265°F (129-30°C). Insoluble in water. Used as a contact insecticide.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
BENDIOCARB is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
Hazard
Poison by ingestion, skin absorption.
Health Hazard
Highly toxic by all routes of exposure; oralmedian lethal doses in rats, mice, guineapigs, and rabbits range at 30–50 mg/kg;cholinesterase inhibitor; toxic symptomsinclude increased salivation, lacrimation,sweating, blurred vision, twitching of muscle, tremor, weakness, vomiting, abdominalcramps, and diarrhea; high doses can causedeath; absorption through skin may be slow.
LD50 oral (rat): 40 mg/kg
LD50 oral (rabbit): 35 mg/kg
LD50 skin (rat): ~600 mg/kg.
Sicherheitsprofil
Poison by ingestion.
Moderately toxic by skin contact. When
heated to decomposition it emits toxic
fumes of NOx. See also CARBAMATES.
mögliche Exposition
A potential danger to those involved
in the manufacture, formulation and application of this carbamate
insecticide which is used against household pests,
in agriculture in seed treatment, and as a foliar spray.
Environmental Fate
Soil. Though no products were identified, the reported half-life in soil is several days
to a few weeks (Hartley and Kidd, 1987). When soil containing bendiocarb was incubated
for 4 weeks, the amount remaining was 30.4–47.2% of the applied amount. After one
application, the amount of bendiocarb recovered was only 0.9–1.3% (Racke and Coates,
1988). Biodegradation of bendiocarb in soil was enhanced if the soil was pretreated with
carbofuran or trimethacarb (Dzantor and Felsot, 1989).
Plant. At planting, bendiocarb was applied at a rate of 1.7 kg/ha. During harvest (110
days following planting), the residues of bendiocarb found in corn (leaves and stems),
husks, cobs and kernels were 12, 5, 4 and 3 ppb, respectively. At an app
Chemical/Physical. Bendiocarb is stable to light but in water hydrolyzes to 2,3-
isopropylidenedioxyphenol, methylamine and carbon dioxide. The hydrolysis half-life at
pH 7 and 25°C is 4 days (Worthing and Hance, 1991).
Stoffwechselwegen
Pathways of bendiocarb metabolism in mammals include hydrolysis to
the benzodioxol-4-ol, hydroxylation of the phenyl ring, hydroxylation at
the N-methyl moiety and conjugation. Extensive pathways reported for
the structurally related carbofuran are not reported for bendiocarb partly
because hydroxylation and subsequent oxidation and conjugation at the
3-position is not possible in bendiocarb although it is a major pathway for
carbofuran. No domation is available for the metabolism of bendiocarb
in plants.

Inkompatibilitäten
Carbamates are incompatible with reducing
agents, strong acids, oxidizing acids, peroxides, and
bases. Contact with active metals or nitrides cause the

release of flammable, and potentially explosive, hydrogen
gas. May react violently with bromine, ketones.
Incompatible with azo dyes, caustics, ammonia, amines,
boranes, hydrazines, strong oxidizers. Keep away from
flammable materials and sources of heat and flame.
Waste disposal
Must be disposed properly by
following package label directions or by contacting your
local or federal environmental control agency, or by contacting
your regional EPA office. Dispose in accordance
with 40CFR165 recommendations for the disposal of pesticides
and pesticide containers.
Vorsichtsmaßnahmen
The preliminary risk assessment of the US EPA showed that applicators, including home
owners, were at risk when mixing or applying the pesticide. Thus, bendiocarb is no longer
sold in the United States. All bendiocarb-containing products in the United States recently
had their registrations cancelled due to concerns over exposure of those applying the
products. In the UK, however, bendiocarb is still registered as a biocide and amateurs can
use it even though it lacks proper warning labels. In view of this, bendiocarb should be
purchased and used only by certii ed and trained applicators. Like all RUPs, management
must be done only by trained and certii ed workers.
