Özet
This study was carried out to determine the residual amounts of picoxystrobin in oriental melon (Cucumis melo L.) grown under plastic house conditions at two different sites. Samples collected over 10 days were extracted using acetonitrile and salting out (using solid sodium chloride) and purified using Florisil SPE cartridges. The analyte was determined using GC-ECD and field-incurred residues were verified using GC-MS. The calibration curve was linear over the range 0.02-2.0 mg/L with a R (2) = 0.9998. The LOD and LOQ were 0.003 and 0.01 mg/kg, respectively. Recoveries, tested at three spiking levels, were satisfactory with rates in the range 87.7-101.5% and relative standard deviations ae
