What is Nabam?

Plain description, key identifiers and synonyms

Nabam is a dithiocarbamate salt that is the disodium salt of ethylenebis(dithiocarbamic acid). A fungicide, algicide and bactericide used on various crops including on cotton, capsicums, onions and rice crops, it is considered to be a carcinogen, so is not licensed for use within the European Union. Mixing nabam with zinc sulfate affords the fungicide zineb. It has a role as an antifungal agrochemical. It is an organic sodium salt and a dithiocarbamate salt. It contains an ethylenebis(dithiocarbamate).

Uses and applications

What the substance is used for, by industry and function

As a result of the Special Reviews on nabam, all food uses were voluntarily cancelled except one FDA-regulated food use on sugar mill grinding, crusher and/or diffuser systems. Pesticides added to sugar mill processing water systems to control microorganisms is an indirect food additive and, therefore falls under FDA jurisdiction. All other uses of nabam are as an industrial biocide in paper mills, water cooling systems, drilling mud and packer fluids and secondary oil recovery water systems.

Agricultural fungicide, biocide in pulp and paper industry.

Plant fungicide, starting material for derivatives that are also pesticides.
