DETERMINATION OF PESTICIDE RESIDUES IN PICKLED VINE (Vitis vinifera L.) LEAVES BY A VALIDATED LC-MS/MS METHOD

Abstract

Pesticides are chemicals used to combat insects, rodents, fungi and weeds, which are agricultural pests. In this study, it was aimed to determine pesticide residues of the pickled vine leaves produced by industrial and traditional methods from Narince variety grown in Tokat. The amounts of pesticides in the pickled vine leaves were determined by the QuEChERS (quick, easy, cheap, effective, rugged and safe) method. As a result of pesticide analysis performed on pickled vine leaves, 13 different pesticide active ingredients were determined and 8 pesticides were found to be above the maximum residue limit (MRL) value. While, the highest substance amounts according to MRL values were cyhalothrin, pyraclostrobin, cypermethrin, boscalid, the most detected pesticide active ingredients were ethiofencarb, isocarbofos, cyhalothrin, respectively. As a consequence of the investigation, it was found that detected some pesticide residue amounts from pickled vine leaves were at a level that would pose a health risk.
