Metam sodium is an organosulfur compound (formally a dithiocarbamate), which is used as a soil fumigant, pesticide, herbicide, and fungicide. It is one of the most widely used pesticides in the United States, with approximately 60 million pounds used in 2001.^[2] Metam sodium is the sodium salt of methyl dithiocarbamate.

Metam sodium can be prepared from methylamine, carbon disulfide, and sodium hydroxide; or from methyl isothiocyanate and sodium thiolate.^[1]

Upon exposure to the environment, metam sodium decomposes to form methyl isothiocyanate.^[3]

Metam sodium is a documented cause of reactive airways dysfunction syndrome.
