Beschreibung

Maneb is a pesticide with fungicide properties and belongs to the carbamate (bis-dithiocarbamate) group. Sensitization occurs mainly in farmers and agricultural workers.

Chemische Eigenschaften

Maneb is a yellow powder or crystalline solid with a faint odor.

Verwenden

Maneb is a complex of manganese with the ethylene bis(dithiocarbamate) anionic ligand. Maneb is a foliate fungicide used to protect crops in agriculture. Maneb is also useful in creating a toxin-based animal (usually primates) model of Parkinson's disease.

Definition

ChEBI: A polymeric complex of manganese with the ethylene bis(dithiocarbamate) anionic ligand. An agrochemical fungicide, it is used to control a variety of diseases including blight, leaf spot, rust, downy mildew and scab.

Allgemeine Beschreibung

Maneb is a yellow powder or crystalline solid. Maneb is denser than water. Contact may irritate skin, eyes and mucous membranes. Maneb may be toxic by ingestion. Likely to generate heat spontaneously upon exposure to air or water. May be sufficient to ignite the material. Maneb is used as a fungicide. Formulations of Maneb include mixing Maneb with many other chemicals such as sulfur, zinc oxide and others to desensitize it. This is done to make Maneb easer for application.

Air & Water Reaktionen

Highly flammable. Soluble in water. Maneb is likely to generate heat spontaneously, especially when wet. The heat may be sufficient to ignite the material. Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids.

Reaktivit?t anzeigen

The BPS Pesticide incident in Helena resulted in an explosion and death of three firemen. The burning of a 1,000 pound sack of Azinphos Methyl or the flashing of Maneb which was present on the facility may have caused the explosion.

Health Hazard

Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.

Brandgefahr

Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated.

Landwirtschaftliche Anwendung

Fungicide: Maneb is an ethylene(bis)dithiocarbamate fungicide used in the control of early and late blights on potatoes and tomatoes and many other diseases of fruits, vegetables, field crops, and ornamentals. Maneb controls a wider range of diseases than other fungicides. It is available as granular, wettable powder, flowable concentrate, and ready-to-use formulations. Maneb is widely used by itself and in combination with other pesticides on a variety of crops. Principal uses in California are for head and leaf lettuce, walnuts, almonds, onions, potatoes and broccoli.

Kontakt-Allergie

Maneb is a pesticide with fungicide properties, belong-ing to the dithiocarbamate group. Sensitization occursmainly in farmers and agricultural workers.

Sicherheitsprofil

Moderately toxic by ingestion. Experimental teratogenic and reproductive effects. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Mutation data reported. A fungcide. May ignite spontaneously in air. When heated to decomposition it emits highly toxic fumes of NOx and SOx. See also MANGANESE COMPOUNDS and CARBAMATES.

m?gliche Exposition

A potential danger to those involved in manufacture, formulation, and application of this broad spectrum dithiocarbamatefungicide. Some dithiocarbamates have been used as rubber components. DFG warns of danger of skin sensitization. The BPS Pesticide incident in West Helena, AK resulted in an explosion and death of three firemen. The burning of a 1000-lb sack of Azinphos Methyl or the flashing of Maneb which was present on the facility may have caused the explosion

Stoffwechselwegen

Maneb and other alkylenebis(dithi0carbamate) fungicides are degraded and metabolised via a common pathway. The primary degradation reaction of maneb in water, soils, plants and animals involves the initial dissociation of the metal complex and decomposition to numerous degradation products including ethylenethiourea (ETU) and ethyleneurea (EU) as major products (Scheme 1).

l?uterung methode

Crystallise this fungicide from EtOH. It is soluble in CHCl3. It is a skin irritant.[Beilstein 4 III 149, 4 IV 234.]

Inkompatibilit?ten

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, water. Dithiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal decomposition of Dithiocarbamate compounds, including carbon disulfide, oxides of sulfur, oxides of nitrogen, hydrogen sulfide, ammonia, and methylamine. Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. Flammable gases are generated by the combination of dithiocarbamate with aldehydes, nitrides, and hydrides. Dithiocarbamate are incompatible with acids, peroxides, and acid halides.

Waste disposal

Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal. Maneb is unstable to moisture and is hydrolyzed by acids and hot water. It decomposes at about 100℃ but may spontaneously decompose vigorously when stored in bulk. Incineration is the preferred disposal means. 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
