Abstract

Flusilazole and triflumizole residues in apple fruits were chemically determined at different periods after spraying of these fungicides under field conditions. The obtained results indicated that, seven days after flusilazole application, unwashed apple fruits were found contained higher residues (0.322 ppm) than the allowed tolerance level (0.2 ppm), while washed and peeled fruits were contained lower residues (0.149 and 0.087 ppm, respectively) after the same period from experiment. These residues were rapidly decreased by elapse of time, so unwashed, washed and peeled apple fruits were contained levels below the allowed MRL i.e. 0.092, 0.008 and <0 ppm, respectively after fourteen days of flusilazole application Accordingly, unwashed apple fruits could be marketed safely 14 days after flusilazole application, while washed and peeled fruits could be used safely after seven days. In the case of triflumizole, unwashed apple fruits were contained 2.030 ppm after five days of application. Such residue is higher than the tolerance value (2.0 ppm), while washed and peeled fruits were contained residues below the tolerance permissive values i.e. 1.010 and 1.970 ppm after three and one days of application, respectively. These values were rapidly decreased by time prolongation, so, unwashed, washed, and peeled apple fruits were contained residues below the allowed tolerance of 1.280, 0.490 and 0.160 ppm at seven days after triflumizole application, respectively. Accordingly, unwashed apple fruits could be marketed safely seven days after triflumizole application, while washed and peeled fruits could used safely three and one days after application, respectively.
