Benomyl Chemical Properties,Uses,Production

Description

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).

Chemical Properties

Benomyl is a white crystalline solid. Faint acrid odor.

Uses

Fungicide; ascaricide.

Uses

Post-harvest systemic fungicide used to control fungi and mildew on cotton, roses, soft fruits, tomatoes, cucumbers and other vegetables.

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.

General Description

Colorless to white crystals or off-white powder. Faint acrid odor.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

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..

Fire Hazard

Literature sources indicate that Benomyl is nonflammable.

Agricultural Uses

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.

Contact allergens

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.

Safety Profile

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.

Potential Exposure

Benomyl is used as an agricultural chemical and pesticide, pharmaceutical, and veterinary drug.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the Benomyl 367 skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Environmental Fate

Biological. Mixed cultures can grow on benomyl as the sole carbon source. It was proposed that benomyl degraded to butylamine and methyl 2-benzimidazole-carbamate (MBC), the latter undergoing further degradation to 2-aminobenzimidazole then to carbon dioxide and other products (Fuchs and de Vries, 1978).
Soil. In soil and water, benomyl is transformed to methyl-2-benzimidazole and 2- aminobenzimidazole (Rhodes and Long, 1974; Ramakrishna et al., 1979; Rajagopal et al., 1984). Benomyl is easily hydrolyzed in soil to methyl-2-benzimidazole carbamat
Plant. On apple foliage treated with a Benlate formulation, benomyl was transformed to MBC. Benomyl dissipated quickly and the reported half-life on foliage was 3–7 days (Chiba and Veres, 1981).
Chemical/Physical. In aqueous solutions, especially in the presence of acids, benomyl hydrolyzes to the strongly fungicidal methyl-2-benzimidazolecarbamate (carbendazim) (Clemons and Sisler, 1969; Peterson and Edgington, 1969; Zbozinek, 1984; Cremlyn, 1991; Worthing and Hance, 1991) and butyl isocyanate (Zbozinek, 1984; Worthing and Hance, 1991). The latter is unstable in water and decomposes to butylamine and carbon dioxide (Zbozinek, 1984). In highly acidic and alkaline aqueous solutions (pH <1 and pH >11), benomyl is completely converted to 3-butyl-2,4-dioxo-[1,2-a]-s-triazinobenzimida zole (STB) with smaller quantities of methyl 2-benzimidazolecarbamate (MBC). In addi tion 1-(2-benzimidazolyl)-3-n-butylurea was identified but only under highly alkaline conditions (Singh and Chiba, 1985).
Emits toxic fumes of nitrogen oxides when heated to decomposition (Lewis, 1990).

Metabolic pathway

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.

Shipping

UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9—Miscellaneous hazardous material, Technical Name Required.

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides (forms toxic oxides of nitrogen). Decomposed in water or otherwise moist conditions.

Waste Disposal

In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. 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.
