Metham sodium is a soil fumigant used as a 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] Metham sodium is the sodium salt of methyldithiocarbamate.
Metham sodium can be prepared from methylamine, carbon disulfide, and sodium hydroxide; or from methyl isothiocyanate and sodium thiolate.[1]
Upon exposure to the environment, metham sodium decomposes to form methyl isothiocyanate.[3]
