“…In some cases, this could impact the interpretation of the results and the proper verification of the origin of a given sample. The PQTL IPP-NRI Sosnicowice Branch found a solution to this problem by interpreting the results using chemometric analysis based on physical and chemical data and chromatography results (Miszczyk et al 2015a ).…”

“…The estimated value of global pesticide sales is approximately €44 billion. In the case of Poland, the value of this market is approximately €0.5 billion (European Commission DG Health and Food Safety 2015 ; Miszczyk et al 2015a ; Miszczyk et al 2015b ). These large amounts of money combined with the legal loopholes and relatively low fines made illegal pesticides trade a fast-growing area of organized crime (Europol 2011 ).…”

Market presence of illegal and counterfeit pesticides is now a global problem. According to data published in 2012 by the European Crop Protection Association (ECPA), illegal products represent over 10% of the global market of plant protection products. Financial benefits are the main reason for the prevalence of this practice. Counterfeit and illegal pesticides may contain substances that may pose a threat to the environment, crops, animals, and humans, inconsistent with the label and registration dossier. In Poland, action against illegal and counterfeit plant protection products is undertaken by the Main Inspectorate of Plant Health and Seed Inspection (PIORiN), the police, the prosecution, and the pesticide producers. Results of chemical analyses carried out by the Institute of Plant Protection - National Research Institute Sośnicowice Branch, Pesticide Quality Testing Laboratory (PQTL IPP-NRI Sosnicowice Branch) indicate that a majority of illegal pesticides in Poland are detected in the group of herbicides. Products from parallel trade tend to have the most irregularities. This article describes the official quality control system of plant protection products in Poland and presents the analytical methods for testing pesticides suspected of adulteration and recent test results.

“…The detection and quantification of adulterants in pesticide products is regarded as a usual part of quality control operations . To achieve this goal and ensure the quality of plant protection products (i.e., pesticides), different chromatographic and spectroscopic techniques have been employed . Many studies have shown that different conventional analytical techniques have been used for analyzing the concentration of adulterants in pesticide formulations, such as liquid chromatography mass spectrometry (LC-MS) and gas chromatography mass spectrometry (GC-MS) for the determination of adulterants in pesticide formulations, high-performance liquid chromatography and gas chromatography for the detection of active ingredients and adulterants present in plant protection products, ultra- performance liquid chromatography–mass spectrometry (UPLC-MS) and nuclear magnetic resonance (NMR) spectroscopy for the analysis of adulterants contained in pesticide formulations, liquid chromatography-tandem mass spectrometry for the quantification of contaminants and adulterants present in pesticide formulations, high-performance liquid chromatography along with diode-array detector (HPLC-DAD) for the simultaneous identification of adulterants and active ingredients in pesticide formulations, and Fourier transform infrared (FTIR) spectroscopy to detect the adulterants present in pesticide products …”

Identification of adulterants in commercial samples of methyl eugenol is necessary because it is a botanical insecticide, a tephritid male attractant lure that is used to attract and kill invasive pests such as oriental fruit flies and melon flies on crops. In this study, Raman spectroscopy was used to qualitatively and quantitatively assess commercial methyl eugenol along with adulterants. For this purpose, commercial methyl eugenol was adulterated with different concentrations of xylene. The Raman spectral features of methyl eugenol and xylene in liquid formulations were examined, and Raman peaks were identified as associated with the methyl eugenol and adulterant. Principal component analysis (PCA) and partial least-squares regression analysis (PLSR) have been used to qualitatively and quantitatively analyze the Raman spectral features. PCA was applied to differentiate Raman spectral data for various concentrations of methyl eugenol and xylene. Additionally, PLSR has been used to develop a predictive model to observe a quantitative relationship between various concentrations of adulterated methyl eugenol and their Raman spectral data sets. The root-mean-square errors of calibration and prediction were calculated using this model, and the results were found to be 1.90 and 3.86, respectively. The goodness of fit of the PLSR model is found to be 0.99. The proposed approach showed excellent potential for the rapid, quantitative detection of adulterants in methyl eugenol, and it may be applied to the analysis of a range of pesticide products.

Picloram and 2,4-D are systemic herbicides used to control a wide range of broad-leaved weeds and post-emergence annual and perennial broad-leaved weeds, respectively. The use of plant protection products containing Picloram and 2,4-D necessitates the development of analytical methods, useful for the laboratories focused on control, for monitoring. In this study, we designed and validated an analytical method for the rapid determination of picloram and 2,4-D by HPLC-DAD. The method involves the extraction of the substances by sonication of the sample with methanol, followed by dilution in acetonitrile, and direct injection on a liquid chromatography system, based on the use of a Gemini C18 column. We used an isocratic mobile elution consisting of acetonitrile and water acidified 1% with H3PO4 (50:50, v/v). We validated the proposed method, which demonstrated linearity within the concentration range of 0.01–0.028 mg/mL for picloram and 2,4-D, with a correlation coefficient (R2) of 0.9993 for picloram and 0.9999 for 2,4-D. We considered precision, repeatability and selectivity in the validation. The repeatability of the method expressed as percent of relative standard deviation (%RSD) was lower than 1% for both substances. The proposed method is suitable for the simultaneous determination of picloram and 2,4-D in pesticide formulations.
