False positive dithiocarbamate findings in cabbage and lilies
"Dithiocarbamates" is the generic term for a group of pesticides that commonly contain sulfur-carbon components (CS2) in their molecular structure.
Typically, dithiocarbamates are detected and quantified as a sum parameter indirectly via the "carbon disulfide" (CS2) contained in them. This means that the individual active substances can usually not be detected.
Plants that naturally contain sulfur or carbon-sulfur compounds can interfere with dithiocarbamate analysis. This can lead to false-positive results. This is known, for example, in Brassicaceae (cruciferous plants, e.g., cabbage varieties and rapeseed) and Allium species (e.g., onions and garlic). In this case, it is necessary to check whether the active application of pesticide active ingredients from the class of dithiocarbamates is the cause of the detected finding.
In our Tentamus labs, we regularly conduct testing for dithiocarbamates. We provide you with fast and reliable results.
