    Effect of long-term storage on pesticide residues in sweet cherries

  • Popis výsledku v původním jazyce

    Control of pesticide residues in crops is generally related to maximum residue levels (MRL). Pesticides present in permitted amounts are important to maintain the quality of fruit during long-term storage. Their absence or decomposition under modern storage conditions can cause acceleration in decay of fruit quality. Fruit treated with plant protection products must contain pesticide active ingredients at levels below MRL to avoid harm to human health. The rate of decomposition of residues depends on a variety of conditions including climate during ripening, precipitation, processing and humidity. Our study aimed at monitoring the dynamics of degradation of the original active substances acetamiprid, boscalid, cyprodinil, fenhexamid, fenpyrazamine, fludioxonil, fluopyram, pyraclostrobin, pirimicarb, tebuconazole, thiacloprid, and trifloxystrobin applied on sweet cherries during storage using various long-term technologies including ultralow oxygen (ULO) and modified atmosphere packing (MAP), as well as application of 1-methylcyclopropen (MCP) and ozone. Multiresidue validated LC-MS/MS method according to the European SANTE/ 11813/2017 guidelines (SANTE, 2017) for monitoring the whole spectrum of the tested pesticides in sweet cherry extracts was used. Extraction was carried out according to the modified QuEChERS method. High performance liquid chromatography coupled to mass spectrometric detector was used. We assumed that type of pesticide and fruit storage conditions may have a profound effect on pesticide residues content. We found these contents below tolerated maximum residue limits when applied at recommended times and depended on period prior to aplication. Low contents of acetamiprid, boscalid, fenpyrazamine, thiacloprid, pirimicarb, and fludioxonil were found when fruit were stored in modified atmosphere packages. A statistically significant difference was noted for tebuconazole, pyraclostrobin and cyprodinil after the use of ozone.
