Sodium dimethyldithiocarbamate hydrate is widely used as a fungicide and bactericide in agricultural applications. It effectively controls fungal diseases in crops, protecting plants from pathogens that can reduce yield and quality. In industrial settings, it serves as a corrosion inhibitor, particularly in water treatment systems, where it helps prevent metal degradation in pipelines and equipment. Additionally, it is employed in the rubber industry as an accelerator in the vulcanization process, enhancing the strength and durability of rubber products. Its chelating properties also make it useful in wastewater treatment, where it aids in the removal of heavy metals from industrial effluents.
