BACKGROUND Mesosulfuron-methyl (MSM) is currently the only available selective herbicide for controlling Aegilops tauschii in wheat fields. Improving the control performance of MSM against Ae. tauschii is crucial for ensuring wheat yield. Herein, strategies to improve the bioactivity of MSM against Ae. tauschii and the underlying mechanism were investigated. RESULTS The efficacy of MSM oil dispersion (MSM-OD, GR 50 = 21.62 g a.i. ha −1 ) on Ae. tauschii was higher than emulsion in water (GR 50 = 59.96 g a.i. ha −1 ) and emulsifiable concentrate (GR 50 = 77.34 g a.i. ha −1 ). A greater retention on Ae. tauschii leaves was responsible for the increased MSM-OD bioactivity. As the particle size decreased from 13.58 to 1.20 μm, the herbicidal activity of MSM-OD towards Ae. tauschii increased 3.07-fold, which was attributed to the small particle size-enabled faster plant absorption of MSM. Polyvinyl alcohol (PVA, 3%) addition in MSM-OD with a small particle size (MSM-OD-S + PVA) increased MSM residue on Ae. tauschii leaves after washing, and thus herbicidal activity. The increased wettability on Ae. tauschii leaves was related to the PVA-induced rainfastness increase of MSM-OD-S. Importantly, MSM-OD-S + PVA at the recommended field rate did not show an adverse effect on wheat growth. CONCLUSION A suitable formulation, reduced particle size and PVA addition can increase the herbicidal activity of MSM against Ae. tauschii , particularly under rainy conditions. These results can provide guidance for the development and application of other herbicides. © 2025 Society of Chemical Industry.

Pesticides are essential for controlling plant diseases and pests in modern agriculture, yet traditional formulations often suffer from poor adhesion, rapid UV degradation, and loss due to rainwater runoff. This study introduces Pro@TA-Cu 2+ -Pal, a novel pH-responsive release system designed to enhance the performance of prochloraz, a widely used fungicide. By integrating tannic acid and copper ions onto palygorskite, this nanocarrier with metal–phenolic networks improves prochloraz wettability and adhesion on leaf surfaces while significantly enhancing UV stability and rainfastness. Under UV exposure, Pro@TA-Cu 2+ -Pal showed a 3.9-fold lower degradation rate than the commercial emulsion-in-water formulation (Pro EW). In simulated rain tests, Pro@TA-Cu 2+ -Pal exhibited superior rain-fastness, retaining >80 % of the applied fungicide on leaf surfaces, whereas Pro EW showed a marked reduction in retention. Pot trials showed that Pro@TA-Cu 2+ -Pal provided excellent control against wheat powdery mildew, outperforming Pro EW in both protective and curative treatments, with more effective and sustained disease control. Importantly, Pro@TA-Cu 2+ -Pal proved safe with no phytotoxicity observed in the crop. These findings highlight the potential of Pro@TA-Cu 2+ -Pal as an economical, eco-friendly, and sustainable solution for improving pesticide efficiency, reducing environmental impact, and supporting long-term crop protection.

Passive radiative cooling (PRC) coatings play a significant role in reducing energy consumption by cooling buildings. Unfortunately, due to the lack of an integrated design, most existing PRC coatings are susceptible to UV aging and rain, and fail to resist aperiodic fire attacks, restricting their practical applications for buildings in the wildland-urban interface (WUI). To fill this research gap, an integrated composition design strategy is proposed to develop a scalable, durable, and fire-safe PRC coating comprising of a molecularly engineered fire-retardant copolymer adhesive, hollow glass microspheres (HGMs), and boron oxide (B 2 O 3 ). Besides intrinsic fire retardancy, the copolymer endows the coating with a strong adhesion to diverse substrates. HGMs enable the coating to show good thermal insulation and a high solar reflectance (>94%), and B 2 O 3 promotes the in situ formation of a robust non-combustible ceramic char layer in fires. The coating achieves an unparalleled fire resistance (UL-94 V-0 rating, LOI: 88.5 vol.%), a high mid-infrared emissivity (>95%) for efficient heat dissipation, and exceptional durability against UV-aging and rain. The performance integration makes as-developed PRC coatings outperform most existing PRC counterparts. This work offers an integrated design solution to developing fire-safe PRC coatings toward safe and sustainable buildings.

In this study, an α-amylase-responsive controlled-release formulation was developed by capping polydopamine onto β-cyclodextrin-modified abamectin-loaded hollow mesoporous silica nanoparticles. The prepared Aba@HMS@CD@PDA were subjected to characterization using various analytical techniques. The findings revealed that Aba@HMS@CD@PDA, featuring a loading rate of 18.8 wt %, displayed noteworthy release behavior of abamectin in the presence of α-amylase. In comparison to abamectin EC, Aba@HMS@CD@PDA displayed a significantly foliar affinity and improved rainfastness on lotus leaves. The results of field trail demonstrated a significantly higher control efficacy against Spodoptera litura Fabricius compared to abamectin EC at all concentrations after 7, 14, and 21 days of spaying, showcasing the remarkable persistence of Aba@HMS@CD@PDA. These results underscore the potential of Aba@HMS@CD@PDA as a novel and persistently effective strategy for sustainable on-demand crop protection. The application of nanopesticides can enhance the effectiveness and efficiency of pesticide utilization, contributing to more sustainable agricultural practices.
