CHEMICAL NAME: 2,2-Dimethyl-1,3-benzodioxol-4-yl methylcarbamate
DEC INGRED. CODE:
TRADE NAME(S): Ficam (56)
FORMULATION(S): 76% wettable powder, 1% dust; 25% oil suspension for
ULV application, 10 granule, and 29% WP plus
pyrethrins and piperonyl butoxide (56).
TYPE: Carbamate insecticide
BASIC PRODUCER(S): Fisons Incorporated

Bedford, MA 01730
STATUS: Restricted use
PRINCIPAL USES: For the control of cockroaches and crickets, carpet
beetles, earwigs, ants, silverfish, wasps, fleas, brown dog ticks,
etc., in foodstores, houses, and other buildings by professional
applicators. Also for control of pests in turf and ornamentals (56).
a. Cockroaches: Bendiocarb is 2-10 times more effective than other
insecticides to German cockroaches (Blatella germanica). LC50 (%
w/v) = 0.0146 as contact spray.
b. Mosquitoes: Bendiocarb shows very high activity as a mosquito
adulticide. In surface contact tests on filter paper, bendiocarb
has an LC50 to adult female Aedes aegypti of 1 mg/m2 and an LC50
to adult female Culex pipiens quinquefasciatus of 10.9 mg/m2
compared to 48 mg/m2 for propoxur.
c. Ants: In surface contact tests involving two species of ants,
bendiocarb showed higher activity than propoxur and chlordane.
Against both species (Monomorium pharaonis, pharoah's ant; Lasium
niger, black ant) bendiocarb was fully effective at rates of 0.3
d. Carpet beetles: Bendiocarb has excellent activity against larvae
of 2 species of carpet beetles exposed to woolen cloth treated
with solutions of bendiocarb in acetone.
Anthrenus flavipes (larvae) 25 ppm (approx.)
Attagenus megatoma (larvae) 100 ppm (approx.)
Attagenus megatoma (adult) 4 mg/m2
Knockdown: Bendiocarb gives quicker knockdown of insects than most
other residual insecticides, but is slower than dichlorvos or
pyrethrin. Time in minutes to achieve 50% knockdown of male Blattella
germanica = 8.
Rate of use Time (mins) to achieve
Insect on Glass Plates 100% knockdown
______ _______________ ______________
Black ant 100 mg ai/m2 4
Black ant 1 mg ai/m2 15
Pharaoh's Ant 1 mg ai/m2 9
In laboratory experiments FICAM W gave a longer residual control of
susceptible, Malathion-resistant, and Diazinon-resistant strains of
Blattella germanica than Chlordane, Diazinon, Malathion, or Baygon (all
Rapid knockdown with good residual activity. Ten weeks control can
be expected. Has no smell and does not stain the treated surface (8a).
II. PHYSICAL PROPERTIES
MOLECULAR FORMULA: C11 H13 NO4 (62)
MOLECULAR WEIGHT: 223.2 (62)
PHYSICAL STATE: Colorless solid (pure compound) (62)
ODOR: Nil or very slight (27)
MELTING POINT: 129-130 C (pure compound) (62)
VAPOR PRESSURE: 660 uPa at 25 C (pure compound) (62)
SOLUBILITY: 40 mg/l water at 25 C (pure compound) (62)
II. HEALTH HAZARD INFORMATION
OSHA STANDARD: None established
NIOSH RECOMMENDED LIMIT: None established
ACGIH RECOMMENDED LIMIT: None established
A. ACUTE TOXICITY
DERMAL: LD50 = 566-600 mg/kg (rat) (62)
Not a skin irritant (27)
LD50 = >1000 mg/kg (rat, 76 WP formulation) (56).
ORAL: LD50 is in the range 40-156 mg/kg; other mammals
respond similarly (62).
LD50 = 179 mg/kg (rat, 76 WP formulation) (56)
EYES: Ficam W sprays do not irritate the eye. However,
aqueous suspensions of Ficam W induce pupillary
contraction, lasting 1-2 hours in the rabbit eye (27).
B. SUBACUTE AND CHRONIC TOXICITY:
In 2-yr feeding trials NEL for rats was 10 mg/kg diet; in 90-day
trials rats receiving 250 mg/kg diet showed no visible toxic effects
IV. ENVIRONMENTAL CONSIDERATIONS
LC50 (96-hr) for rainbow trout is 1.55 mg/l. Toxic to honeybees,
LD50 0.1 ug/bee (62).
Little or no hazard to birds, fish, and beneficial insects.
Biological magnification unlikely. Nonphytotoxic (1).
Soil studies in both aerobic and anaerobic conditions indicate
breakdown of the parent compound to nontoxic metabolites (27).
Toxicity to birds is similar to toxicity to small mammals. Ficam W
is highly toxic to fish. Avoid contamination of aquaria. LC50 for
bluegill is 1.76 ppm ai and for rainbow trout 0.70 ppm ai. Ficam W is
highly toxic to beneficial insects. Care must be taken to prevent
contamination of flowering vegetation (28a).
Approximate Residual Period: Several weeks on inert surfaces; foliage
residues break down rapidly (1).
V. EMERGENCY AND FIRST AID PROCEDURES
The chemical information provided below has been condensed
from original source documents, primarily from "Recognition and
Management of Pesticide Poisonings", 3rd ed. by Donald P. Morgan,
which have been footnoted. This information has been provided in
this form for your convenience and general guidance only. In
specific cases, further consultation and reference may be required
and is recommended. This information is not intended as a sub-
stitute for a more exhaustive review of the literature nor for the
judgement of a physician or other trained professional.
If poisoning is suspected, do not wait for symptoms to develop.
Contact a physician, the nearest hospital, or the nearest Poison
FREQUENT SYMPTOMS AND SIGNS OF POISONING BY CARBAMATE PESTICIDES
DIARRHEA, NAUSEA, VOMITING, ABDOMINAL PAIN, PROFUSE SWEATING,
SALIVATION, and BLURRED VISION are frequently reported. Other common
symptoms have been dyspnea, tremor, muscle twitching, ataxia, and
headache. Temporary paralysis of the extremities has also occurred.
Most reported illnesses have not exceeded a few hours, and the
prognosis is generally better than in organophosphate intoxications.
However, in severe poisonings, one should anticipate the possibility of
RESPIRATORY DEPRESSION, pulmonary edema, and convulsions. Continuing
absorption of intermediate quantities may cause protracted MALAISE,
weakness, and anorexia, resembling influenza (25).
SKIN CONTACT: Wash with soap and water (25).
INGESTION: If victim is alert and respiration is not depressed,
give Syrup of Ipecac, followed by 1-2 glasses of water to induce
vomiting; adults, 30 ml; children (under 12 years), 25 ml (25).
NOTES TO PHYSICIAN:
Administer ATROPINE SULFATE intravenously, or intramuscularly if IV
injection is not possible.
In MODERATELY SEVERE poisoning: Adult dosage: 0.4-2.0 mg repeated
every 15 minutes until atropinization is achieved (tachycardia,
flushing, dry mouth, mydriasis). Maintain atropinization by repeated
doses for 2-12 hours, or longer, depending on severity of poisoning.
Dosage for children under 12 years: 0.05 mg/kg body weight repeated
every 15 minutes until atropinization is achieved. Maintain
atropinization with repeated dosage of 0.02-0.05 mg/kg.
SEVERELY POISONED individuals may exhibit remarkable tolerance to
atropine; twice the doses suggested above may be needed.
Pralidoxime (Protopam (TM)-Ayerst, 2-PAM) is of doubtful value in
poisonings by carbamate inhibitors of cholinesterase. Atropine alone
is almost always an adequate antidote (25).
VI. FIRE AND EXPLOSION INFORMATION
To be developed.
Ordinarily not mixed with other materials. Do not use with oil (1).
VIII. PROTECTIVE MEASURES
STORAGE AND HANDLING: Harmful or fatal if swallowed. May be absorbed
through skin. Avoid contact with eyes, skin, and clothing. Avoid all
contact by mouth; avoid working in spray mist; wash hands and exposed
skin before eating, drinking or smoking after work. Do not store near
feed or food products. Remove or cover all foodstuffs before
application; protect food preparing equipment, surfaces, and eating
utensils from contamination during application (56).
PROTECTIVE CLOTHING: Wear rubber or PVC gloves and face shield when
handling concentrate (56).
