Dissipation of Penconazole in Tomatoes and Soil


Dissipation of penconazole was estimated in tomatoes fruits cultivated in field 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 0.74 and 1.21 mg kg−1 for tomatoes fruits and soil, respectively. The residues dissipated below the maximum residues limit of 0.2 mg kg−1 after 15 days. The half-life value (T1/2) and preharvest interval of penconazole were 5.61 and 15 days, respectively. While (T1/2) of penconazole in soil was 15.51 days. Thus, a waiting period of 15 day was suggested for the safe consumption of penconazole treated Tomatoes.
