説明
Mancozeb is a fungicide of the ethylene-bis-dit-hiocarbamate
group. It is present in Rondo-M
with pyrifenox. Occupational exposure occurs mainly
in agricultural workers, in vineyard workers or in
florists.
化学的特性
Grayish-yellow powder
使用
Mancozeb is a mixture of Maneb (M163500) and Zineb, a manganese and zinc (1:1) complex mixture with the ethylene bis(dithiocarbamate) anionic ligand. Mancozeb is a foliate fungicide used to protect cr
ops in agriculture. Mancozeb has a broader and more effective fungacidal activity than either of its component on their own. Mancozeb also significantly enhances the copper activity against several ba
cteriosis.
农业用途
Fungicide: Mancozeb is used to control a wide variety of fungal
diseases, including potato blight, leaf spot, scab (on apples
and pears), and rust (on roses). It is used on fruits, vegetables,
nuts and field crops, and many more. It is also used as
a seed treatment of cotton, potatoes, corn, safflower, sorghum,
peanuts, tomatoes, flax, and cereal grains.

環境運命予測
Plant. Undergoes metabolism in plants to ethyl thiourea, ethylene thiuram disulfide,
thiuram monosulfide and sulfur (Hartley and Kidd, 1987).
Chemical/Physical. Decomposes in acids releasing carbon disulfide. In oxygenated
waters, mancozeb degraded to ethylene thiuram monosulfide, ethylene diisocyanate, ethylene
thiourea, ethylenediamine and sulfur (Worthing and Hance, 1991).
代謝経路
Mancozeb is a mixture containing maneb and zineb as the active ingredients.
Maneb and zineb and other alkylenebis( dithiocarbamate) fungicides
are degraded and metabolised via a common pathway. The primary
degradation reaction of maneb and zineb in water, soil, 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. See zineb
and maneb summaries for detailed descriptions.
輸送方法
UN2771 Dithiocarbamate and Thiocarbamate
pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-
Poisonous materials.
不和合性
Combustible material. Dust may form
explosive mixture in air. Decomposes in temperatures
above 170C. Keep away from water, acid, oxidizing
materials. 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.
Corrosive to iron, copper brass, and zinc metals, especially
in the presence of moisture. Contact with lime, moisture
can cause decomposition. Decomposes on prolonged
storage. Degradation produces ethylene thiourea.
廃棄物の処理
Disposal Method Suggested:
Generators of waste (equal to or greater than 100 kg/mo)
containing this contaminant, EPA hazardous waste number
N450, must conform to USEPA regulations for storage,
transportation, treatment, and disposal of waste. Dispose of waste material as hazardous waste using a licensed disposal
contractor to an approved landfill. Dispose of contents and
container to an approved waste disposal plant. Containers
must be disposed of properly by following package label
directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA
office. All federal, state, and local environmental regulations must be observed. Do not discharge into drains or
sewers. A potential candidate for liquid injection incineration at a temperature range of 650 to 1600C and a residence time 0.1 to 2 seconds. Also, a potential candidate for
rotary kiln incineration at a temperature range of 820 to
1600C and residence times of seconds for liquids and
gases, and hours for solids.
