Abstract
Long-chain molecules play a vital role in agricultural production and find extensive use as fungicides, insecticides, acaricides, herbicides, and plant growth regulators. This review article specifically addresses the agricultural biological activities and applications of long-chain molecules. The utilization of long-chain molecules in the development of pesticides is an appealing avenue for designing novel pesticide compounds. By offering valuable insights, this article serves as a useful reference for the design of new long-chain molecules for pesticide applications.

Li M, Di X, Jiang Z. Enantioselective separation, analysis and stereoselective dissipation of the chiral pesticide cloquintocet-mexyl using a modified QuEChERS method by high-performance liquid chromatography tandem mass spectrometry. CHEMOSPHERE 2022; 291:133084. [PMID: 34848224 DOI: 10.1016/j.chemosphere.2021.133084] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 11/13/2021] [Accepted: 11/24/2021] [Indexed: 06/13/2023]
Abstract
An efficient and novel enantioseparation method was successfully developed and validated to quantify the enantiomers of cloquintocet-mexyl in soil, millet, enoki mushroom, oilseed rape, and watermelon using a modified QuEChERS technique combined with HPLC-MS/MS. This method showed reliable performances for determining both enantiomers of cloquintocet-mexyl in all five matrices. The limits of detection and limits of quantification were in the range of 0.06-0.15 μg kg-1 and 0.2-0.5 μg kg-1, respectively. Good linearities were obtained with correlation coefficients ≥0.9954. The mean recoveries were between 84.1% and 111.5%, with relative standard deviations ranging from 1.2% to 9.8% at three spiked levels. Additionally, the study of stereoselective dissipation of cloquintocet-mexyl in soil indicated that (R)-cloquintocet-mexyl was preferentially degraded. This work is the first to describe a chiral analytical method and enantioselective behavior of cloquintocet-mexyl and provide basic data for the risk evaluation of cloquintocet-mexyl in food and environmental safety.

Simultaneous determination of pinoxaden, cloquintocet-mexyl, clodinafop-propargyl ester and its major metabolite in barley products and soil using QuEChERS modified with multi-walled carbon nanotubes coupled with LC-MS/MS. Biomed Chromatogr 2021; 36:e5303. [PMID: 34957590 DOI: 10.1002/bmc.5303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 11/30/2021] [Accepted: 12/02/2021] [Indexed: 11/06/2022]
Abstract
Herein, a modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method with multi-walled carbon nanotube (MWCNT) as a dispersive solid-phase extraction was developed for simultaneous determination of pinoxaden (PXD), cloquintocet-mexyl (CLM), clodinafop-propargyl ester (CPE) and its major metabolite (clodinafop, CP) in barley grass powder, barley grain, and soil using liquid chromatography-tandem mass spectrometry (LC-MS/MS). We found that MWCNT as an absorbent could improve the recoveries of the tested analytes, particularly CP, in complex matrices. Under the optimum conditions, the established MWCNT modified QuEChERS coupled with LC-MS/MS method exhibited excellent linearity (R2 ) of ≥ 0.9912, low limits of detection (LODs) and quantification (LOQs) of 0.02-0.07 and 0.29-1.26 μg/kg, and acceptable recoveries of 80-130% with intra-and inter-day relative standard deviations (RSDs) < 10.5%. No strong matrix effect (ME) has been observed on the respective samples. The method was successfully applied to monitor the tested analytes in the representative field incurred samples. Conclusively, the proposed method is sensitive and reliable and could be used to monitor the residues of PDX, CLM, CPE, and CP in complicated agro-products and soil matrices.
