Widespread use of chemical pesticides in agriculture production has brought up concerns regarding the accumulation of residues in food and agricultural environment and endangering human health and ecological balance. Cucumber is of a fresh use vegetable with high consumption in Iran and has more contamination due to short period between spraying and harvest time. This experiment were carried out to investigate the residues of Fenpropathrin (EC 10%), in a cucumber cultivar in greenhouse (Storm). Cucumber plants was sprayed at recommended doses (2 g/lit) and Samples were collected 1 hour, 1, 3, 5, 7 & 10 days intervals after treatment. Further purification achieved using a silica solid-phase extraction (SPE) cartridge and pesticides residues were analyzed using GC-MS.Result showed that Fenpropathrin levels below maximum residue level (0.5 mg/kg) were detected 3 days after application and no residues were detected on the 10th day.
