“…In Galicia, Northwest Spain, viticulture represents a main support of its economy, and due to the extreme weather conditions in this region, the use of fungicides is necessary for the conservation of the vineyards. However, they can be primarily transported from agricultural fields to surface waters through surface runoff [3,4]. The presence of fungicide residues has been reported in rivers, lakes, groundwater, and even tap water at concentration levels of hundreds of µg/L [5][6][7].…”

“…Due to this permeable fabric substrate and sponge-like porous architecture of sol-gel sorbent coating, the FPSE membrane has 400 times higher sorbent loading onto the substrate compared to SPME fiber and high surface area to facilitate the highly efficient analyte adsorption via sorbent-analyte interaction [19][20][21]. The strong, chemically bonded coating provides high chemical and solvent stability, being suitable for direct exposure to sample solution in a broad pH range (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), and for the direct desorption with any organic solvent or mixtures to maximize the quantitative recovery of the extracted analytes. Moreover, the different FPSE sol-gel coating formulations can be easily adjusted to the type of substrate (i.e., cellulose/polyester/fiber glass) in order to maximize the selectivity of the FPSE membrane based on the physicochemical properties of the target analytes.…”

A rapid environmental pollution screening and monitoring workflow based on fabric phase sorptive extraction-gas chromatography-tandem mass spectrometry (FPSE-GC-MS/MS) is proposed for the first time for the analysis of 17 widespread used fungicides (metalaxyl, cyprodinil, tolylfluanid, procymidone, folpet, fludioxonil, myclobutanil, kresoxim methyl, iprovalicarb, benalaxyl, trifloxystrobin, fenhexamid, tebuconazole, iprodione, pyraclostrobin, azoxystrobin and dimethomorph) in environmental waters. The most critical parameters affecting FPSE, such as sample volume, matrix pH, desorption solvent and time, and ionic strength were optimized by statistical design of experiment to obtain the highest extraction efficiency. Under the optimized conditions, the proposed FPSE-GC-MS/MS method was validated in terms of linearity, repeatability, reproducibility, accuracy and precision. To assess matrix effects, recovery studies were performed employing different water matrices including ultrapure, fountain, river, spring, and tap water at 4 different concentration levels (0.1, 0.5, 1 and 5 µg/L). Recoveries were quantitative with values ranging between 70-115%, and relative standard deviation values lower than 14%. Limits of quantification were at the low ng/L for all the target fungicides. Finally, the validated FPSE-GC-MS/MS method was applied to real water samples, revealing the presence of 11 out of the 17 target fungicides.

In order to screen effective fungicides, three Zn (II) complexes, [ZnL14 (NO3)2]·2H2O·2EtOH (1), [ZnL24 (NO3)2] (2), and [ZnL34 (DMF)2](NO3)2 (3), (L1 = paclobutrazol, L2 = diniconazole, and L3 = hexaconazole), were synthesized and characterized by elemental analysis, FT‐IR spectroscopy, and single‐crystal XRD. The antifungal activities of these complexes were then evaluated against four selected fungi using the mycelial growth rate method. The resulting data indicate that all the complexes show the enhanced antifungal activities than the corresponding ligand and mixtures. And, the interactions between the metal salt and ligands in the three complexes seem to be synergistic. According to the study of the influence of the structures on the activity, complex 2 with C=C linkage and 2,4‐dichlorophenyl moieties enhances the bioactivity significantly, especially against Wheat gibberellic (II). Density functional theory (DFT) calculations were carried out to help explain the enhanced bioactivity of the Zn (II) complexes. Meanwhile, all complexes are excellent grow‐regulators, especially complex 3. The resulting data show that the complexes based on triazole fungicides have the potential applications in agriculture.

“…Therefore, rapid breeding of resistant strains is urgently needed. [1][2][3][4] Interestingly, the complexation of transition metals with pesticides has attracted considerable interest of chemists [5][6][7] due to their potential advantages such as enhanced persistence, longer shelf life, reduced mammalian toxicity, and the conversion of non-systemic pesticides to systemic pesticides. [8][9][10] Considering these advantages and synthetic accessibility of the complexes, they are promising to serve as lead compounds to screen and improve bioactivity for applications.…”

Four Zn(II) complexes, [ZnL2(SO4)]n (1), [ZnL4(H2O)2]•2(NO3)•4EtOH (2), [ZnL2Cl2]•L (3), and [ZnL2Br2]•L (4) (L = uniconazole), were synthesized using a hydrothermal method and characterized by elemental analysis, FT‐IR spectroscopy, and single‐crystal XRD. Complex 1 formed a one‐dimensional polymer chain. However, complexes 2‐4 were obtained as zero‐dimensional mononuclear coordination compounds. The antifungal activities of these complexes were then evaluated against four selected fungi using the mycelial growth rate method. The resulting data indicate that all complexes show better antifungal activities than their ligands and mixtures. In addition, the interactions between the metal salts of complexes 1‐4 and uniconazole seem to be synergistic. Furthermore, the polymer chain structure of complex 1 significantly enhanced the bioactivity, especially against Botryosphaeria ribis (I). Density functional theory (DFT) calculations were carried out to help explain the enhanced bioactivity after the formation of Zn(II) complexes. The resulting data show that the HOMO–LUMO energy gaps of complexes 1‐4 (0.0578, 0.0946, 0.1053, and 0.1245 eV) are smaller than that of the free ligand (0.1247 eV) and correlate with the antifungal activity of the zinc complexes.
