Abstract

Background: Nowadays, increasing the use of pesticides to manage the agriculture production resulted in increased pesticide residues in final products and concerns about environmental pollution and prevalence of emerging diseases. This study aims to investigate the residual amount of Phosalone toxin in the early and late varieties of peach orchards in Saman city located in Chaharmahal and Bakhtiari province.

Methods: In this study, 60 samples of early and late peach varieties of peach orchards were selected randomly. Phosalone residues in early and late peach varieties before and after washing, and after peeling were extracted by QUECHERS method and the amount of extracted toxin were measured by high-performance liquid chromatography (HPLC). The data were analyzed using SPSS v.24 software.

Results: Phosalone residues in early peach varieties before and after washing were 3.55 ± 0.94 and 0.31 ± 0.29 mg/kg, respectively. The concentration of Phosalone residues in unwashed early and late peach varieties before washing was 3.17 ± 0.97 mg/kg but decreased to 0.64 ±0.74 mg /kg after washing. Peeling reduced 97.79% of the Phosalone residues in late peach. Early and late peaches covered by the plant pathology clinic and unwashed late peaches not covered by plant pathology clinic were significantly (P < 0.05) higher than the Iranian national standard (2 mg/kg).

Conclusion: Washing and peeling the peach significantly decreased the toxin residues. In order to minimize the risk of exposure to Phosalone residues, integrated pest control management programs are essential.
