| Maneb Usage And Synthesis |
| Preparation | Manganese ethylenebis(thiocarbamate) is made by adding disodium ethylenebis( dithiocarbamate) (also, known as Nabam, commercially available) to an aqueous solution of manganese(II) sulfate:
NaSC(=S)NHCH2CH2NHC(=S)SNa + MnSO4 → C4H6MnN2S4 + Na2SO4
Alternatively, the compound may be prepared by neutralizing an aqueous solution of disodiummethylenebis(dithiocarbamate) (Nabam) with acetic acid followed by addition of manganese(II) chloride solution. |
| Description | Maneb is a pesticide with fungicide properties and belongs to the carbamate (bis-dithiocarbamate) group. Sensitization occurs mainly in farmers and agricultural workers. |
| Chemical Properties | Brown powder. Decomposes on heating. Partially soluble in water; soluble in chloroform. |
| Chemical Properties | Maneb is a yellow powder or crystalline solid with a faint odor. |
| Uses | Maneb is a contact fungicide that provides protection against a wide variety of fungal diseases (including leaf spots, blight, rust, downy mildew, scab, etc.) in field crops, fruits, vines, vegetables, ornamentals, potatoes, turf, berries and forestry. |
| Uses | 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. |
