Abstract

Turkey, especially the Aegean region, has very suitable lands for olive cultivation. In this work, the olive leaves extracts were treated with pesticide solution and also Bordeaux mixture. Olive varieties in their natural environment were collected after 1 year, and the amount of pesticides they contained was measured. As a result of the QuEChERS method using LC-MS/MS and GC-MS/MS techniques, no pesticide residues were detected in any samples. The pesticide residues determined in the samples used in this study do not exceed the maximum limits specified in the Turkish Food Codex and the European Commission. There are no quantifiable residues of abamectin, acetamiprid, azoxystrobin, difenoconazole, diflubenzuron, diflufenican, dimethoate, dodine, emamectin benzoate, indoxacarb, lufenuron, malathion, novaluron, phosmet, pyriproxyfen, spinosad, thiacloprid, and triflumuron were detected in any olive samples by using LC-MS/MS method. Also, alpha-cypermethrin, beta-cyfluthrin, cyflutrin, deltamethrin, and lambda-cyhalothrin were not detected in samples by GC-MS/MS method. Accordingly, they agree with the results found. The results obtained showed that the pesticide solution used protected the olives from pests and did not have a harmful effect on the olives.
