개요

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).

화학적 성질

Benomyl is a white crystalline solid. Faint acrid odor.

용도

Fungicide; ascaricide.

용도

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

용도

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.

Literature sources indicate that Benomyl is nonflammable.

농업용

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.

색상 색인 번호

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.

잠재적 노출

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

환경귀착

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).

신진 대사 경로

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.

Degradation

Benomyl (1) was stable under strongly acidic conditions (i.e. 5N HCl; Singh et al., 1992). Under mildly acidic conditions, benomyl was converted into carbendazim (MBC, 2) through the loss of n-butyl isocyanate (3). The mechanism of this reaction involves interaction between the electron pair at the N-1 position and the proton on the n-butylcarbamoyl nitrogen. The formation of this hydrogen bond leads to proton abstraction and the release of 3 (Calmon and Sayag, 1976a). Under alkaline conditions, the formation of MBC became secondary to the formation of 3- butyl-2,4-dioxo-s-triazino[1,2-a]benzimidazole(4 ) such that compound 4 was the major degradate at pH 13 (Calmon and Sayag, 1976b; Singh and Chiba, 1985). The DT50 values of benomyl at 25 °C in pH 5,7 and 9 solutions were 3.5, 1.5 and <1 hour, respectively (WHO, 1993). The relative stability of benomyl in strongly acidic solution was attributed to the protonation of the molecule (Singh et al., 1990).
Carbendazim (2) decomposed under alkaline conditions via the cleavage of the amide linkage to yield 2-aminobenzimidazole (2-AB, 5) (Watkins, 1976; Zbozinek, 1984). In pH 9 solution, the hydrolytic DT50 for MBC was ca. 54 days (WHO, 1993). Under extreme alkaline conditions, compound 4 was converted into 1-(2-benzimidazolyl)-3-n-butylurea (6) via the cleavage of the carbamoyl moiety (White et al., 1973). Butyl isocyanate (3), once formed, hydrolysed rapidly in aqueous solution to yield n-butylcarbamic acid (7) and n-butylamine (8) (Calmon and Sayag, 1976a). These products are shown in Scheme 1.
Photolysis was not a significant degradation pathway for benomyl in sterile pH 5 solution (Powley, 1985) under natural sunlight.

비 호환성

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.

폐기물 처리

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.
