The dissipation of the fungicides captan, cyprodinil, fludioxonil, dithianon, and tebuconazole and of the insecticides chlorpyrifos, fenitrothion, and malathion was studied, following a single treatment of different cultivars of pears, apples, and peaches. The study was conducted in northern Italy, over two successive growing seasons (2004 and 2005). The treatments were performed by the farmers involved, in line with their usual practice. At various time intervals from treatment to harvest, representative samples of fruit were collected and analyzed for pesticide residues. In some cases, concentrations lower than the maximum residue levels (MRLs) were found immediately after treatment. In all trials a rapid decline in pesticide concentrations was observed leading to residues at harvest greatly below the MRLs.
在对梨、苹果和桃子的不同品种进行单次处理后,研究了杀菌剂克菌丹、嘧菌环胺、咯菌腈、二噻农和戊唑醇以及杀虫剂毒死蜱、杀螟硫磷和马拉硫磷的消散情况。该研究在意大利北部连续两个生长季节(2004年和2005年)进行。处理由相关农民按照他们的常规做法进行。从处理到收获的不同时间间隔,采集水果的代表性样本并分析农药残留。在某些情况下,处理后立即发现浓度低于最大残留限量(MRLs)。在所有试验中,均观察到农药浓度迅速下降,导致收获时的残留量大大低于MRLs。
