The residual protective effect of sodium n-methyldithiocarbamate (NaMDC) fumigant was investigated in Douglas-fir timbers in a bridge in western Oregon using fungal colonization and levels of methylisothiocyanate (MITC; the primary fungitoxic breakdown product of NaMDC) as the measures of protection.
The most important of these is methylisothiocyanate (MITC), a highly effective fungicide.
Decomposition of metham sodium to methylisothiocyanate as affected by wood species, temperature, and moisture content.
When incorporated into moist aerated soil, dazomet is degraded into several volatile intermediate products including methylisothiocyanate (MITC).
Abbreviations: MITC, methylisothiocyanate; DAT, days after treatment.
The major breakdown product of metam sodium, methylisothiocyanate (MITC), is a known skin irritant at high concentrations (>1%).
Summary of toxicity data on methylisothiocyanate (MITC).
Methylisothiocyanate (MITC), the decomposition product of dazomet, was used as a measure of effectiveness.
Methylisothiocyanate (MITC), a crystalline solid material that is the active breakdown product of NaMDC, was developed, first in gelatin capsules but later in a self-contained vial system (Morrell et al.

Among the systems that emerged from this research were solid methylisothiocyanate
