Dynamics of pesticides decomposition in sweet cherry fruits at different technologies of long-term storage, ultra-low oxygen and modified atmosphere packing, and after post-harvesting application of 1-methylcyclopropen and ozone has been studied. We assumed that type of pesticide and fruit storage conditions may have a profound effect on pesticide residues content. Therefore, levels of residues after applying combinations of active ingredients including acetamiprid, boscalid, cyprodinil, fenhexamid, fenpyrazamine, fludioxonil, fluopyram, pyraclostrobin, pirimicarb, tebuconazole, thiacloprid, and trifloxystrobin were monitored. We found these contents below tolerated maximum residue limits when applied at recommended times and depended on period prior to withdrawal. Low contents of acetamiprid, boscalid, fenpyrazamine, thiacloprid, pirimicarb, and fludioxonil were found when fruit were stored in modified atmosphere packages. Ozone affected degradation of tebuconazole, pyraclostrobin, and cyprodinil. However, differences between storage regimens were not statistically significant (p ≥ 0.05). Kinetic of degradation was studied with fruits stored after treatment with 1-methylcyclopropen and ozone.
研究了在不同长期储存技术、超低氧和气调包装条件下，以及在采后应用1-甲基环丙烯和臭氧后，甜樱桃果实中农药的分解动态。我们假设农药类型和果实储存条件可能对农药残留量有深远影响。因此，监测了包括啶虫脒、嘧菌酯、嘧菌环胺、苯酰菌胺、唑螨酯、咯菌腈、氟吡菌酰胺、吡唑醚菌酯、抗蚜威、戊唑醇、噻虫啉和肟菌酯在内的活性成分组合施用后的残留水平。我们发现，在推荐时间施用时，这些含量低于耐受的最大残留限量，并且取决于停药前的时期。当果实储存在气调包装中时，发现啶虫脒、嘧菌酯、唑螨酯、噻虫啉、抗蚜威和咯菌腈的含量较低。臭氧影响戊唑醇、吡唑醚菌酯和嘧菌环胺的降解。然而，储存方案之间的差异无统计学意义（p≥0.05）。研究了用1-甲基环丙烯和臭氧处理后储存的果实的降解动力学。
