Bulletin of environmental contamination and toxicology 2013 FebDissipation of penconazole was estimated in peach, plum, apricot, and mango fruits cultivated in different farms using QuEChERS method for sample preparation and High performance liquid chromatography with diode array detector. Following one application of normal dose 25 mL 100 L(-1) water, the average initial deposits of penconazole were observed to be 0.44, 0.35, 0.66 and 1.12 mg kg(-1) for peach, plum, apricot, and mango, respectively. The residues dissipated below the maximum residues limit of 0.1 mg kg(-1) after 15, 7, 10 and 21 days for peach, plum, apricot, and mango, respectively. The half-life value (T(1/2)) and pre-harvest interval of penconazole were 7.2 (12), 2.48 (12), 1.53 (7) and 4.54 (21) days for peach, plum, apricot, and mango, respectively. Thus, a waiting period of 21 days was suggested for the safe consumption of penconazole treated mango.
