摘要

背景氟唑胺（THI）是一种全球重要的噻唑酰胺杀菌剂，对茄枯丝核菌特别有效。由于传统剂量下的效果有限，我们利用硅化SiO2纳米颗粒（THI/SiO2 Pickering乳剂）构建了环保型水包油（O/W） Pickering乳剂。结果THI/SiO2 Pickering乳状液分散性良好，平均粒径为~170 nm。与THI的商业悬浮液（SC）相比，THI/SiO2 Pickering乳状液具有更好的界面性能和抗液滴弹跳性能。结果表明，THI/SiO2皮克林乳剂对茄灰病菌的杀灭效果优于市售SC。结论THI/SiO2 Pickering乳剂具有良好的界面性能和杀菌活性，在茄茄疫病防治中具有一定的应用前景。©2025化学工业协会。

Eco-friendly thifluzamide/SiO2 oil-in-water Pickering emulsion with high adhesion on leaf for improving fungicidal efficacy.

BACKGROUND Thifluzamide (THI) is a globally significant thiazole amide fungicide, particularly effective against Rhizoctonia solani. Because of its limited efficacy at traditional dosages, we constructed an eco-friendly oil-in-water (O/W) Pickering emulsion utilizing silanized SiO2 nanoparticles (THI/SiO2 Pickering emulsion). RESULTS The THI/SiO2 Pickering emulsion exhibited excellent dispersion, with an average droplet size of ~170 nm. In comparison with a commercial suspension concentrate (SC) of THI, the THI/SiO2 Pickering emulsion demonstrated better interface properties and improved anti-droplet bounce performance. A fungicidal assay revealed that THI/SiO2 Pickering emulsion was more effective than commercial SC in controlling R. solani. CONCLUSION These findings show that the THI/SiO2 Pickering emulsion possessed superior interfacial properties and fungicidal activity, indicating potential application in the management of R. solani. © 2025 Society of Chemical Industry.
