The fate of three pesticides (vinclozolin, dimethoate, cyproconazole)
in plums, from field treatment to the drying process, was studied. Onl
y vinclozolin showed measurable residue concentrations at harvest, whi
le dimethoate was completely degraded after two weeks and cyproconazol
e was present at negligible levels just after treatment. During the dr
ying process into prunes, the residues were not reduced during the fru
it washing stage, but the drying stage led to complete elimination of
vinclozolin residues.
