Integrated management of Meloidogyne incognita and Fusarium oxysporum in cucumber by combined application of abamectin and fludioxonil

The southern root-knot nematode (Meloidogyne incognita) and Fusarium wilt (Fusariutn oxysporum) are major constraints in cucumber production worldwide. Co-infection of these pathogens results in a disease complex which is difficult to control. In China, growers apply nematicides and fungicides separately to control M. incognita and F. oxysporum, respectively, which requires a great amount of labor thus increasing production costs. We hypothesized that the combined application of nematicides and fungicides would significantly reduce the labor cost, and control M. incognita and F. oxysponun. In this study, toxicity of abamectin and fludioxonil was determined against M. incognita and F. oxysporum, respectively, in the laboratory, and the efficacy of a combination of abamectin and fludioxonil (abamectin + fludioxonil) for control of M. incognita and F. oxysporum simultaneously was evaluated under field conditions. In the laboratory, abamectin was highly toxic to secondstage juveniles (J2) of M. incognita with the median lethal concentration (LC50) of 2.60 mg L-1 and fludioxonil inhibited colony growth of F. oxysporwn on potato dextrose agar (PDA) with the median effective concentration (EC50) of 0.34 mg L-1. In the field trials, abamectin + fludioxonil at 300 and 375 g ha(-1) was effective in reducing population levels of M. incognita and incidence of Fusarium wilt in two consecutive years. Moreover, abamectin + fludioxonil at 375 g ha(-1) significantly (P < 0.05) increased cucumber fruit yield by 45.23% and 40.85% in two years, respectively, compared to the untreated control. The yield increasing effect by the combined treatment was significantly greater than either treatment alone. Results from this study indicated the simultaneous application of abamectin + fludioxonil was effective for the control of the M. incognita and F. oxysportun disease complex in cucumber production, while enhancing cucumber fruit yield.

Unusual Electronic Effects of Ancillary Ligands on the Perfluoroalkylation of Aryl Iodides and Bromides Mediated by Copper(I) Pentafluoroethyl Complexes of Substituted Bipyridines

Several perfluoroalkylcopper compounds have been reported previously that serve as reagents or catalysts for the perfluoroalkylation of aryl halides. However, the relationships between the reactivity of such complexes and the electronic properties of the ancillary ligands are unknown, and such relationships are not well-known in general for copper complexes that mediate or catalyze cross coupling. We report the synthesis and characterization of a series of pentafluoroethylcopper(I) complexes ligated by bipyridine ligands possessing varied electronic properties. In contrast to the limited existing data on the reactivity of L2Cu(I)-X complexes bearing amine and pyridine-type ligands in Ullmann-type aminations with aryl halides, the reactions of aryl halides with pentafluoroethylcopper(I) complexes bearing systematically varied bipyridine ligands were faster for complexes bearing less electron-donating bipyridines than for complexes bearing more electron-donating bipyridines. Analysis of the rates of reaction and the relative populations of the neutral complexes [(R(2)bpy)CuC2F5] and ionic complexes [(R(2)bpy)(2)Cu][Cu(C2F5)(2)] formed by these reagents in solution suggests that this effect of electronics on the reaction rate results from an unusual trend of faster oxidative addition of aryl halides to [(R(2)bpy)CuC2F5] complexes containing less electron-donating R(2)bpy ligands than to those containing more electron-donating R(2)bpy ligands.

Highly thermally stable mesoporous Poly(cyanate ester) featuring double-decker-shaped polyhedral silsesquioxane framework

In this study we prepared cyanate ester-functionalized double-decker silsesquioxane (DDSQ) nanoparticles through a sequence of hydrosilylation of nadic anhydride (ND) with DDSQ and then treat with 4-aminophenol to provide DDSQ-ND-OH, and reaction with cyanogen bromide (BrCN) to form DDSQ-ND-OCN (a bis-phenyl cyanate ester DDSQ). After thermal curing of DDSQ-ND-OCN, we obtained mesoporous poly(cyanate ester) (PCE)/DDSQ frameworks that displayed high thermal stabilities and char yields since the inorganic DDSQ nanoparticles were dispersed in the PCE matrix homogeneously, as revealed using electron microscopy. Thermal polymerization at 210 degrees C provided a PCE/DDSQ framework having a thermal decomposition temperature (516 degrees C) and char yield (70 wt%); these values increased to 600 degrees C and 81 wt%, respectively, after thermal treatment at 420 degrees C. More interestingly, these mesoporous PCE/DDSQ frameworks displayed electrochemical properties better than those of other non-carbonized materials.

CTAB-Assisted Synthesis of C@Na3V2(PO4)(2)F-3 With Optimized Morphology for Application as Cathode Material for Na-Ion Batteries

C@Na3V2(PO4)(2)F-3 samples were obtained by using Cetyl Trimethyl Ammonium Bromide (CTAB) as a surfactant. The optimization of the added amount allowed controlling the eventual nanometric morphology of the particles. The morphological and structural properties of these samples were discussed in the light of solid-state techniques as X-ray diffraction, Raman and XPS spectroscopies, and electron microscopy. Galvanostatic test in sodium half-cells revealed that the nanometric spherical and porous particles provided by the addition of intermediate amounts of CTAB showed excellent cycling stability and superior high rate capability reflected in the minimization of the cell polarization and the determination of a high apparent diffusion coefficient.

Ferrocenylated imine- and amine(secondary/tertiary)- phosphine P boolean AND N ligands and their Pd(II) complexes: Synthesis and structural characterization

A new family of ferrocenylated P<^>N ligands where the nitrogen donor is either of an imine or amine (secondary/tertiary), was synthesized. The condensation reaction between diphenylphosphino propylamine and formyl ferrocene led to the formation of imine ligand [(eta(5)-C5H5)Fe[(eta(5)-C5H4)CH=N-(CH2)(3)-PPh2)}] (1), which on reduction with NaBH4 gave secondary amine ligand [((eta(5)-C5H5)Fe[(eta(5)-C5H4)CH=N-(CH2)(3)-PPh2)}] (2). Additionally, nucleophilic substitution reaction of diphenylphosphino ethyl/propyl amine with [FcCH(2)NMe(3)(+)][I-] salt leads to tertiary-amine ligand [(eta(5)-C5H5)Fe[(eta(5)-C5H4)CH2](2)-N-(R-PPh2) where R = C2H4 (3) and C3H6 (4). The newly synthesized ferrocenylated ligands were then complexed with Pd(II) giving [cis(kappa(2)-P<^>N)PdCl2] type complexes (5-8), where imine, secondary amine, and tertiary amine ligands act as a bidentate ligand. The molecular structures of ligand (3), and complexes (5), (6), and (7) have also been determined by X-ray crystallography. In the molecular structures of these complexes, the Pd(II) center presents a distorted square-planar geometry. During the isolation of ligand (4), corresponding phosphine oxide (4A) along with a phosphonium salt (4B) was also isolated as by-products and were characterized by X-ray crystallography. The preliminary catalytic evaluation of complex (7) in the Suzuki-Miyaura cross-coupling reaction of arylboronic acids with aryl bromides was performed. (C) 2020 Elsevier B.V. All rights reserved.

Synthesis of sp(3)-Enriched beta-Fluoro Sulfonyl Chlorides

A three-step approach to the synthesis of sp(3)-enriched beta-fluoro sulfonyl chlorides starting from alkenes is reported. The method was successfully applied to a wide range of acyclic and cyclic substrates, bearing either an exocyclic or an endocyclic double bond. The procedure worked with a wide range of substrates and tolerated a number of functional and protecting groups. Moreover, the target cyclic compounds were obtained as single cis diastereomers on a multigram scale. The title compounds are promising building blocks for drug discovery that can be used to obtain sp(3)-enriched beta-fluoro and alpha,beta-unsaturated sulfonamides.

Occurrence and fate of ten sulfonamide antibiotics in typical wastewater treatment plants in the City of Jinan of Northeastern China

This study investigated the concentration levels and removal efficiencies of sulfonamide antibiotics in the effluents of different sections of wastewater treatment plants (WWTPs) and explored the removal of sulfonamide antibiotics from the effluent of each section by modified activated carbon. The results showed that the wastewater treatment process has a certain removal effect on the nine sulfonamide antibiotics except on the negative removal of trimethoprim, which had a removal rate of less than 60%. The effect of WWTP pH was found to be obvious, demonstrating a negative correlation with the occurrence of antibiotics. The occurrence of sulfadimethoxine and sulfachloropyridazine was found to be mainly affected by total nitrogen, NH3-N and NO3–N. After equilibrium adsorption by MAC-1 (activated carbon modified by FeCl3) and MAC-2 (activated carbon modified by hexadecyltrimethylammonium bromide) for 24 h, the removal efficiencies of sulfonamide antibiotics in the effluent of each section ranged from 87.37% to 100%. Our results suggest that the removal rates of ten sulfonamide antibiotics in WWTPs are not clear.

Aggregation Behavior of Mixed Micellar System of Dodecyl Sulfate-Based Surface-Active Ionic Liquids and Anionic Surfactant in Aqueous Media

Mixed micellization behavior of dodecyl sulfate-based ionic liquids, i.e., 1-propyl-3-methylimidazolium dodecyl sulfate [C(3)mim][DS] and 1-hexyl-3-methylimidazolium dodecyl sulfate [C(6)mim][DS] with sodium dodecyl sulfate (SDS), is investigated at (298.15, 308.15, and 318.15) K in aqueous medium. For this, the conductometric measurements are carried out to evaluate the critical micelle concentrations (cmc), ideal critical micelle concentration (cmc*), degree of counterion dissociation (g), thermodynamic parameters, micellar mole fraction of ionic liquids, and interaction parameter (beta) of the mixed system based on the different proposed models given in the literature. Further surface tension measurements have been carried out to confirm the value of cmc obtained via a conductivity study for all the studied systems at 298.15 K. Other surface parameters, such as surface tension at cmc (gamma(cmc)), surface pressure ((cmc)), surface excess (Gamma(max)), and minimum area per molecule (A(min)), have also been evaluated for both the systems.

Variability in care for children with severe acute asthma in Latin America

Background: Care variability for children with severe acute asthma has been well documented in high-income countries, yet data from low- and middle-income regions are lacking. We sought to characterize the magnitude of practice variability in the care of Latin American children to identify opportunities for standardization of care. Methods: A cross-sectional study performed through a retrospective analysis of contemporaneously collected data of children with severe acute asthma admitted to a center contributing to the LARed Network registry between May 2017 and May 2019. Centers were grouped by geographic location: Atlantic (AT), South Pacific (SP), and North Central (NC). Results: Among 434 children, most received care in hospitals in the AT group (54% [235/434]), followed by the NC (23% [101/434]) and SP (23% [98/434]) groups. The majority of children in the AT (92% [215/235]) and SP (91% [89/98]) groups received nebulized salbutamol/albuterol, while metered-dose inhalers were preferred in the NC group (72% [73/101]). There was a wide variation in the use of antibiotics: AT (57% [135/235]), SP (48% [47/98]), and NC (14% [14/101]). The same was true for ipratropium bromide: AT (67% [157/235]), SP (90% [88/98]), and NC (17% [17/101]), and aminophylline: AT (57% [135/235]), NC (5% [5/101]), and SP (0% [0/98]). High-flow nasal cannula was the preferred respiratory support modality in the AT (60% [141/235]) and NC (40% [40/101]) groups, while bilevel positive airway pressure (BiPAP) use was more common in the SP group (80% [78/98]). Conclusion: We identified significant variability in care for severe acute asthma. Our findings will help to inform the design of future studies, quality improvement initiatives, and development of practice guidelines within Latin America.
