Residual Characteristics of Bistrifluron and Chlorantraniliprole in Strawberry (Fragaria ananassa Duch.) for Establishing Pre-Harvest Residue Limit

Abstract

BACKGROUND: Pesticide residue analysis is essentially required for safety evaluation of agricultural products. Bistrifluron and chlorantraniliprole have been currently considered as potentials to deeply evaluate their residues in agricultural products because they are frequently found in strawberry. This work was performed to investigate the residual patterns of bistrifluron and chlorantraniliprole in strawberry after harvest. METHODS AND RESULTS: Strawberry was treated with bistrifluron and chlorantraniliprole 0, 1, 2, 3, 5, 7 and 10 days before harvest under greenhouse conditions. The strawberry samples were subjected to solvent and solid phase extractions followed by LC-MS/MS analysis. There covery percentages of bistrifluron and chlorantraniliprole for tified in the control samples ranged from approximately 82 to 103% with the method limit of 0.005 mg/kg. The concentrations of bistrifluron and chlorantraniliprole in strawberry samples decreased significantly in 10 days after treatment, giving the safety levels of 0.04 to 0.06 mg/kg at 10 days after application, as considered maximum residue limit. The half-lives of bistrifluron and chlorantraniliprole based on first order kinetics were determined to 6.3 days and 6.4 days, respectively. CONCLUSION: Bistrifluron and chlorantraniliprole are suggested to use in strawberry 10 days before harvest to reach residual safety levels.

Dissipation Kinetics and the Pre-Harvest Residue Limits of Acetamiprid and Chlorantraniliprole in Kimchi Cabbage Using Ultra-Performance Liquid Chromatography-Tandem Mass Spectrometry

“…A number of dissipation studies have investigated acetamiprid residues in zucchini, watermelon, chili, tea, asparagus, parsley, and swiss chard [16,17,18,19,20,21,22]. The dissipation of chlorantraniliprole has also been studied in tomato, grape, strawberry, and cauliflower [23,24,25,26]. Chen, et al [12] performed a similar field study of acetamiprid on Chinese cabbage ( Brassica pekinensis Skeels ).…”

Insecticides chlorantraniliprole and flubendiamide in Aster scaber: Dissipation kinetics, processing effects, and risk assessment

“…CAP exhibits long half-lives in perilla leaves (19.3 days [ 10 ]) because of its systemic properties [ 32 ]. However, it rapidly degrades in fruits, such as strawberry (4.7–6.4 days [ 33 ]) and tomato (3.3 days [ 34 ]). In contrast to other diamines, FBD is not fully systemic in plants [ 32 ].…”

Stable Isotope Analysis of Residual Pesticides via High Performance Liquid Chromatography and Elemental Analyzer–Isotope Ratio Mass Spectrometry

“…The diamide pesticides such as cyantraniliprole (CYN) and chlorantraniliprole (CHL) used in this study are common due to their promising pest management effects via selective, uncontrolled calcium homeostasis in insects [ 20 ]. These pesticides were not applied in previous CSIA work, which has focused only on concentration determination in which CHL [ 21 , 22 ] and CYN [ 23 ] were used as parental compounds as well as metabolites [ 1 ]. Here, we sought to investigate an HPLC/EA–IRMS method for a CSIA approach in residual pesticides.…”
