“…2 LC-MS/MS chromatograms in MRM acquisition mode of pymetrozine spiked in matrices (0.01 mg kg −1 ): a standard b water; c soil; d rice straw; e brown rice; and f rice husk residue was below limit of detection after 21 days. The results showed that a sharp decline of residue level in the first 2 weeks, which was similar to that 79.02 and 87.28 % of the initial residue levels had already dissipated after 10 days of application at the recommended dose and double dose, respectively (Hong et al 2011). …”

The dissipation and residue of pymetrozine in rice field ecosystem were studied based on a novel and reliable analytical method for pymetrozine in paddy water, soil, rice straw, brown rice, and rice husk. The pymetrozine residues were extracted with acetonitrile and cleaned up by Carb-NH 2 SPE cartridge and determined by high-performance liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS). The dissipation of pymetrozine followed first-order kinetics and its half-lives ranged from 1.7 to 1.8 days in paddy water, 5.1 to 5.7 days in soil, and 2.3 to 2.6 days in rice straw, respectively. At harvest time, the highest final residues of pymetrozine varied in soil among three geographical fields and were below the limit of detection in rice tissues. The recommended dosage was considered to be safe for human beings and animals, and the results were helpful in setting maximum residue limit for pymetrozine in rice.

“…The pesticide dilution effect (f') was calculated from remaining pesticide and weight of peach over 10 days [8]. For the two cases in which growth rate was not considered and those in which the 1.77-fold growth rate was considered, the patterns of residue in relation to growth at the triple dose are given in Figure 6.…”

The biological half-life and final residue levels of buprofezin and teflubenzuron were examined in peaches over a 14-day cultivation period. The residue levels of buprofezin and teflubenzuron were analyzed by chromatographic method with recovery ranging from 84.0% to 96.6%. The biological half-lives of buprofezin and teflubenzuron were 4.88 and 11.49 days at the standard dose, and 4.40 and 10.86 days at a triple dose, respectively. The initial concentration of buprofezin exceeded the maximum residue limit (MRL) set in Korea, but the concentration decreased to below the MRL within 6 days after application. The initial and persisting concentrations of teflubenzuron were all below the prescribed MRL. The final residue levels of buprofezin and teflubenzuron were 0.17 and 0.10 mg•kg −1 following a standard single dose, and 0.20 and 0.23 mg•kg −1 following a triple dose, respectively. The final residue levels of buprofezin and teflubenzuron were also compared with the good agricultural practices standards of the United States and Italy.

“…As pymetrozine is widely used across the world, many papers on the analysis of pymetrozine in soils, terrestrial plants and meat products are available. Pymetrozine residues are usually extracted from different matrices using acetonitrile (Camino-Sanchez et al, 2010;Dias et al, 2013;Zhang, Zhang, Xu, Li, & Wang, 2015) and methanol (Hong, Cho-Rong, Jong-Sung, & Kyu-Seung, 2011). The extracts were cleaned up using solid-phase extraction (Zhao et al, 2014) or liquid-liquid partitioning with organic solvent such as dichloromethane (Zhang et al, 2015), ethyl acetate (Hong et al, 2011), or dispersive solid-phase extraction (Cabizza, Satta, Falconi, Onano, & Uccheddu, 2007).…”

The present study investigates the occurrence of pymetrozine residues in cauliflower samples obtained from six cauliflower‐producing areas of China during fixed time periods in 2017 and estimates the dietary risk of pymetrozine in cauliflower. A liquid chromatography with tandem mass spectrometry method was developed and validated to detect pymetrozine in cauliflower. The samples were extracted using 20 mL of acetonitrile and purified with dispersive solid‐phase extraction using C18 as sorbent. The limit of quantification of pymetrozine was 0.008 mg/kg in cauliflower. The recoveries of the analyte were 82.04–95.18% with RSD <8.45%. The calibration curves for pymetrozine showed good linearities in the concentration range 0.004–2.0 mg/L with determination coefficients (R2) >0.999. Pymetrozine dissipated rapidly in cauliflower with a half‐life of <4 days. The terminal residues of pymetrozine were <0.008–0.0881 mg/kg in cauliflower at 7, 10 and 14 days after spraying from six sites. The routine washing process removed about half amount of the pymetrozine in cauliflower; the reduction ratios were 51.0–52.8%. The dietary risk assessment indicated that pymetrozine did not exhibit obvious dietary health risks in cauliflower when good agricultural practices were implemented.
