Widely used as a soil fumigant in agriculture to control nematodes, fungi, insects, and weed seeds. It is applied before planting crops such as strawberries, tomatoes, and potatoes to sterilize the soil and reduce pest infestations. Often generated in situ from precursors like sodium methyldithiocarbamate for safer handling. Also used in some industrial settings as a biocide and in the synthesis of certain pesticides and pharmaceuticals. Its high volatility allows effective distribution in soil, but requires careful management due to toxicity and environmental concerns.
