Pesticide Residues in Grape Leaves Collected from Manisa, Turkey

In this study, 318 pesticide residues were analyzed in 232 grape leaf (Vitis vinifera) samples provided from the Manisa region of Turkey in 2017. In these analyzes, the QuEChERS method was used by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The results obtained were evaluated according to the Turkish Food Codex (TFC) Pesticide Maximum Residue Limit (MRL). Pesticide residues were found in eighty five (36.6%) samples (22.4%) in total 52 samples detected pesticide active substance above MRLs it was. Of the 318 pesticide agents analyzed in the grape leaves, 42 different pesticides and 210 different results were obtained, and 92 of these results were compared with the MRL values. The most common factor in the analyzed grape leaves was metalaxyl, the active ingredient above the MRLs of TGK was azoxystrobin. Results showed that pesticide residues in grape leaves were detected at a high level
