Beschreibung
Benomyl, a tan-coloured crystalline solid/powder, is a systemic fungicide with a characteristic
odour. It belongs to the benzimidazole family. Benomyl decomposes at high
temperature. Benomyl is essentially insoluble in water. It is stable under normal storage
conditions but will decompose to carbendazim in water. On decomposition by heat, benomyl
produces toxic fumes including nitrogen oxides.
Benomyl is a systemic and broad-spectrum fungicide that is currently registered for use
in more than 50 countries on more than 70 crops for the control of diseases in fruit trees, nut
crops, vegetables, cereals, tropical crops and ornamentals, turf, and many field crops. Benomyl
is marketed as a wettable powder and as a dry flowable formulation (dispersible granules).
Chemische Eigenschaften
Benomyl is a white crystalline solid. Faint acrid
odor.
Verwenden
Benomyl is a systemic fungicide with both protective and curative
activities. It is effective against more than 190 different fungal diseases in
stone fruits, pome fruits, tropical and subtropical fruit crops, grapes, fruiting
vegetables, cereals, etc. It is effective against fungal diseases caused by
Ascomycetes and Basidiomycetes spp., including leaf spots, blotches and
blights; fruit spots and rots; sooty mould; scabs, bulb, corm and tuber
decays; blossom blights; powdery mildew; certain rusts; common soil
borne crown and root rots.
Definition
ChEBI: A member of the class of benzimidazoles that is the methyl ester of [1-(butylcarbamoyl)-1H-benzimidazol-2-yl]carbamic acid. A foliar fungicide used to control a wide range of Ascomycetes and Fungi Imperfecti in
a wide range of crops.
Allgemeine Beschreibung
Colorless to white crystals or off-white powder. Faint acrid odor.
Air & Water Reaktionen
Insoluble in water.
Reaktivität anzeigen
Benomyl is incompatible with strong acids, peroxides and strong oxidizers. Decomposed by strong alkalis. Also decomposes on storage with water .
Hazard
High toxicity by ingestion. Upper respira-
tory tract irritant, male reproductive, testicular, and
embryo/fetal damage. Possible carcinogen.
Health Hazard
Mildly toxic in rodent by ingestion, inhalation, and absorption through skin; large dosescan produce effects of carbamate poisoning;teratogenic and mutagenic effects reported;carcinogenic potential not known; mild skinirritant.
LD50 oral (rat): 10,000 mg/kg
LD50 skin (mouse): 5600 mg/kg
LD50 skin (wild bird): 100 mg/kg
Benomyl metabolizes to carbendazim(MBC) and 5-HBC. Animal studies indicatedthat benomyl and its metabolites rapidlyeliminated out within 24 hours of exposure.They do not accumulate in tissues over longterm exposure..
Brandgefahr
Literature sources indicate that Benomyl is nonflammable.
Landwirtschaftliche Anwendung
Fungicide: Used as a pre-harvest systemic fungicide and as a
post-harvest dip. Used on arable and vegetable crops, apples,
soft fruit, nuts, mushrooms, lettuce, tomatoes and turf.
In California, the top five crops for which benomyl is used
are pistachios, table and raisin grapes, almonds, strawberries
and wine grapes. All uses of benomyl products in the
United States was phased out with a deadline of December
31, 2003. Not approved for use in EU countries.

Kontakt-Allergie
Benomyl is a fungicide, derived from benzimidazole.
Cases of sensitization were reported in horticulturists and
florists. It is however, at most, a weak sensitizer, with
possible false-positive patch reactions, or with crossreactions
after previous exposure to other fungicides.
Sicherheitsprofil
Poison by ingestion.
Mildly toxic by inhalation. Experimental
teratogenic and reproductive effects. Human
mutation data reported. A human skin irritant. When heated to decomposition it
emits toxic fumes of NO,. See also
CARB AMATES.
mögliche Exposition
Benomyl is used as an agricultural
chemical and pesticide, pharmaceutical, and veterinary drug.
Carcinogenicity
Benomyl was genotoxic, causing chromosome
aberrations in vitro and in vivo, but it does
not directly act with DNA.
Stoffwechselwegen
When benlate is degraded by the singlet oxygen
photoreaction either in methanol or in aqueous
hydrochloric solutions, carbendazim is identified as a
major degradation product with the other nine
degradation products from both reactions, including 2-guanidinobenzimidazole, benzimidazole, and 2,4'-and
2,5'-bibenzimidazoles which are identical to the
photodegradation products of carbendazim by the
singlet oxygen photoreaction in aqueous hydrochloric
acid solution.
