Abstract
A preliminary investigation has shown that methyl isothiocyanate is the principal product of decomposition of sodium N-methyldithiocarbamate (metham-sodium) when applied to soil. Methyl isothiocyanate can react with aqueous ammonia hydroxide to afford N-methylthiourea, but surface applications of ammonium compounds to assist this reaction in soil were found to be without significant effect under outdoor conditions. Concentrations of I p. p. m. of isothiocyanate and 50 p. p. of N-methylthiourea in soil under similar conditions were phytotoxic.
