What is metam sodium used for?
Metam sodium (sodium N-methyldithiocarbamate) is widely used in agriculture as a soil fumigant, pesticide, herbicide, and fungicide.
How is metam sodium made?
Metam sodium can be prepared from methylamine, carbon disulfide, and sodium hydroxide; or from methyl isothiocyanate and sodium thiolate. Upon exposure to the environment, metam sodium decomposes to form methyl isothiocyanate.
What is dichlobenil herbicide?
