Dithiocarbamate fungicide residues in agricultural products were determined by measuring the decomposition products. Dithiocarbamate fungicides were divided into two groups, ziram type (dimethyldithiocarbamate) and zineb type (ethylene-bis-dithiocarbamate). The ziram type was extracted with chloroform and measured as dimethylamine after acid hydrolysis. The dimethylamine was quantitated by gas chromatography of its benzenesulfonyl derivative using a flame photometric detecting system (FPD). The

The recovery of ziram added to crops was in the range of 64 to 93%. That of zineb added to crops was in the range of 67 to 91%. Three samples were found to contain 1.8-4.8ppm of ethylene-bis-dithiocarbamate.
