Dissipation residue studies of benomyl, carbendazim, procymidone and iprodione in winw grapes were carried out during three consecutive years. In spite of the observed persistence of these residues, levels found in the grapes at harvest time were in all cases below the respective maximum residue limits (MRL). The results of the residues transfer from grapes into wine obtained through different microvinification procedures revealed the total transfer of the residues of benomyl and carbendazim, showing an increase of their concentration in the wines, as a result of the yield of the microvinifications. On the contrary, for iprodione and procymidone global average transfer rates of the residues from grapes into wines of respectively 30% and 20% were found
