Abstract

Fungicides based on dithiocarbamates have been used to protect crops from fungal diseases for more than half a century. The purpose of this work was to show the potential impact of improper potato storage on the analysis of mancozeb and other dithiocarbamates. The resulting field samples were divided into two parts. The first part was subjected to sample preparation without violation of storage conditions. Sample preparation of the second part of the sample was carried out after artificially simulated storage violation conditions. The method for the analysis of dithiocarbamates is based on the acid hydrolysis of the sample with the formation of carbon disulphide and its subsequent analysis using GC-FPD. The results of the analysis showed the content in the experimental and control samples of a large amount of carbon disulphide, which is not a product of the hydrolysis of mancozeb. Thus, it is not possible to estimate the correct amount of mancozeb.
