Useful:

• Chemical Classes: Pesticides -> Dithiocarbamates (Pesticide)
• Canonical SMILES: C(CNC(=S)[S-])NC(=S)[S-].[Mn+2]
• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract.
• Effects of Long Term Exposure: Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys and central nervous system. This may result in kidney impairment and neurologic and neuropsychiatric disorders (manganism).
• Description: Maneb is a pesticide with fungicide properties and belongs to the carbamate (bis-dithiocarbamate) group. Sensitization occurs mainly in farmers and agricultural workers.
• 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. 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.
