A new spot test has been developed for the detection of dithiocarbamate fungicides such as mancozeb, propineb and zineb at nkg level in soil and water. The colour formation is based on the decomposition of dithiocarbamate to carbon disulphide which reacts with plumbite i ' alkaline medium to form a brown complex that finally converts to black lead sulphide. The coloured product exists as a brig...
