Dazomet is a common soil fumigant that acts as a herbicide, fungicide, slimicide,[3] and nematicide.

The decomposition of dazomet releases methyl isothiocyanate (MITC) a gas toxic to pests that would prevent or kill plant growth.

Dazomet has also been proven to be effective in the prevention of Phellinus noxius, or brown root rot disease.

Exposure to dazomet can occur through several means; interaction with unincorporated granules, inhalation of it decomposition product, MITC, and/or water runoff.

The fragment peak at 89 m/z represents the loss of MITC, which is the major, gaseous degrade of dazomet.
