Mechanism and strategy of self‐assembly of quaternary ammonium surfactant molecules to regulate pesticide droplet impact and wetting of hydrophobic surfaces

Pest Management Science (2024)

Lifei He Xiaolong Liu Xiangyu Kong Pengjiu Zhang Zhongfang Liu

Surfactants regulate the interaction between pesticide droplets and the surfaces of plants on which they are sprayed. The influence of the key structural functional groups of surfactants on the interaction between pesticide droplets and hydrophobic pear leaves has not been explored. The behavior of Imidacloprid (Imid) droplets regulated by cationic quaternary ammonium surfactants with different structures on hydrophobic pear leaves and their bouncing dynamics were studied.

Engineering Pyreno[1,2-b:8,7-b′]dithiophene-Based Conjugated Polymers for Efficient and Stable Perovskite Solar Cells

Macromolecules (2024)

Yaohang Cai Lifei He Lingyi Fang Yuyan Zhang Jing Zhang

The advancement of p-type conjugated polymers with optimized electrical properties, morphology, and heat tolerance is essential for n-i-p-type perovskite solar cells. Herein, we present a novel conjugated polymer, p-PDT144-E, composed of alternating units of 4,4,7,7-tetrakis(4-hexylphenyl)-4,7-dihydropyreno[1,2-b:8,7-b′]dithiophene (PDT144) and 3,4-ethylenedioxythiophene. This copolymer was synthesized via a palladium-catalyzed direct arylation polycondensation method. Compared to the corresponding homopolymer p-PDT144 synthesized by oxidative polymerization, p-PDT144-E exhibited an elevated highest occupied molecular orbital energy level, facilitating faster hole extraction and enhanced hole conductivity. Additionally, p-PDT144-E demonstrated an increased glass temperature and a more uniform film morphology. When used as a hole transport material along with the air doping promoter 4-(tert-butyl)pyridinium 1,1,2,2,3,3-hexafluoropropane-1,3-disulfonimide, perovskite solar cells incorporating p-PDT144-E achieved an average power conversion efficiency (PCE) of 25.5%, surpassing reference cells using spiro-OMeTAD (average PCE of 24.7%) under identical conditions. Furthermore, p-PDT144-E-based cells exhibited excellent operational stability at 45 °C and thermal storage stability at 85 °C.

The relationship between features enabling SDHI fungicide binding to the Sc‐Sdh complex and its inhibitory activity against Sclerotinia sclerotiorum

Pest Management Science (2020)

Yangyang Gao Lifei He Jiamei Zhu Jiagao Cheng Beixing Li

Abstract BACKGROUND A new generation of succinate dehydrogenase inhibitors (SDHIs) with high efficiency and broad‐spectrum antifungal activity has been frequently used in crop production. Sclerotinia stem rot is a major disease of various plants and crops caused by Sclerotinia sclerotiorum . Although benzovindiflupyr and isopyrazam reportedly have high activity against S. sclerotiorum , little is known about the bioactivity of different SDHIs classes against S. sclerotiorum or the mechanism of their differential antifungal activity. RESULTS The in vitro tests revealed that the pyrazole‐4‐carboxamides of SDHIs (benzovindiflupyr, isopyrazam, fluxapyroxad, pydiflumetofen) had the highest activity against S. sclerotiorum followed by pyridine carboxamides (boscalid), pyridinyl‐ethyl benzamides (fluopyram) and thiazole carboxamides (thifluzamide), and of these thifluzamide showed poor antifungal activity with EC 50 values greater than 6.01 mg L −1 . The pyrazole‐4‐carboxamides of SDHIs showed satisfactory protective and curative activity against Sclerotinia stem rot. After treatment with the pyrazole‐4‐carboxamides of SDHIs, mitochondrial function in S. sclerotiorum decreased significantly. The enzyme activity assays revealed a lower affinity between thifluzamide and the Sc ‐ Sdh complex than was observed for the other six fungicides, with IC 50 values ranging from 0.0036 to 1.2088 μmol L −1 . Additionally, the docking positions of fungicides were similar, yet binding energies were different in the docking study with the Sdh complex. The correspondingly weaker hydrogen bonds may be responsible for the poor activity of thifluzamide against S. sclerotiorum . CONCLUSION Understanding different binding features of various SDHIs classes with the Sc‐Sdh complex might be beneficial for the design and development of highly effective broad‐spectrum fungicides to ensure high yield and quality in crops by reducing fungicide use. © 2020 Society of Chemical Industry

Regulating Droplet Wetting and Pinning Behaviors on Pathogen-Modified Hydrophobic Surfaces: Strategies and Working Mechanisms

Journal of Agricultural and Food Chemistry (2021)

Lifei He Lei Ding Beixing Li Wei Mu Peiqiang Li

Hydrophobic surfaces modified by pathogens in agricultural production are one of the main reasons to reduce the utilization of pesticides. Adding surfactants to pesticide solutions is a common method to improve their wetting and spreading properties. In this work, the interaction mechanism between pathogen-modified hydrophobic surfaces and mixtures of surfactants and a pesticide was studied in detail. The interaction mechanism was determined by characterizing the wetting and spreading behaviors of droplets on cucumber powdery mildew leaves at different growth stages. When surfactants were added, droplets on cucumber powdery mildew leaves were in the Wenzel wetting state, the pinning force weakened, the contact line speed accelerated, and the adhesion force increased. We explained the micellar state and aggregation behavior of surfactant molecules in a pesticide solution that was applied to the surface of cucumber powdery mildew leaves. Droplets of solutions containing nonionic surfactants easily formed semibald micelles, binding to the pathogen of powdery mildew, whereas droplets containing cationic surfactants did not do so. Because of the electrostatic interaction between cationic surfactant molecules and powdery mildew pathogens, cationic surfactant molecules did not wet the pathogens very well, so we suggest adding nonionic surfactants rather than cationic surfactants to improve the wetting and spreading of pesticide solutions on cucumber powdery mildew leaves. This study provides new insights into enhancing the wetting and deposition of droplets on pathogen-modified hydrophobic surfaces.

Target gene selection for sprayable dsRNA‐based biopesticide against Tetranychus urticae Koch (Acari: Tetranychidae)

Pest Management Science (2025)

Yifei Wang Yuanpeng Duan Ming‐Rui Liu Meifeng Ren Yue Gao

Because of the excessive use of synthetic chemicals, the two-spotted spider mite, Tetranychus urticae Koch, a highly polyphagous pest, has developed comprehensive resistance to a broad spectrum of pesticides with diverse modes of action, raising severe concerns over agroecosystems and human health. To resolve this emerging issue, we initiated a project to develop double-stranded RNA (dsRNA)-based biopesticides against T. urticae, aiming for a species-specific and sustainable pest management alternative. To examine the uptake of dsRNAs using the egg-soaking delivery method, we fluorescently labeled extraneous dsRNAs, and later showed that T. urticae dsRNAs can permeate through eggshell in a time-dependent manner within the first 24 h. For target gene screening, silencing of Prosbeta-1 and -5 resulted in the highest mortality (>90%) and a dark body phenotype in T. urticae. Notably, each target gene was effective in both avermectin laboratory susceptible and field resistant populations. As such, Prosbeta-5 was selected as the candidate target gene for subsequent spray-induced gene silencing (SIGS). After two rounds of spray at day 5 and day 12, SIGS led to a substantial suppression of T. urticae populations (>90%). Our combined results suggest viable molecular targets, confirm the feasibility of SIGS against T. urticae, and lay the foundation for the development of dsRNA-based biopesticides to control this devastating pest. © 2025 The Author(s).
