In the present work, the simultaneous quantification of the fungi- cides thiabendazole (TBZ), fuberidazole (FBZ), carbendazim (CBZ) and
fenarimol (FM), the herbicides dicamba, imazaquin (IMZQ) and norflurazon (NFZ), the insecticides carbaryl (CBL) and methiocarb, and the plant growth activator 1-naphthol (NAP) is attempted in vege- tables samples. Table 1 shows structures, functions and dissociation constants of the studied compounds [4–11].
