Botanical repellents represent one of the main ways of reducing the use of synthetic pesticides and the contamination of soil and hydric resources. However, the poor stability and rapid degradation of these compounds in the environment hinder their effective application in the field. Zein nanoparticles can be used as eco-friendly carrier systems to protect these substances against premature degradation, provide desirable release characteristics, and reduce toxicity in the environment and to humans. In this study, we describe the preparation and characterization of zein nanoparticles loaded with the main constituents of the essential oil of citronella (geraniol and R-citronellal). The phytotoxicity, cytotoxicity, and insect activity of the nanoparticles toward target and nontarget organisms were also evaluated. The botanical formulations showed high encapsulation efficiency (>90%) in the nanoparticles, good physicochemical stability, and effective protection of the repellents against UV degradation. Cytotoxicity and phytotoxicity assays showed that encapsulation of the botanical repellents decreased their toxicity. Repellent activity tests showed that nanoparticles containing the botanical repellents were highly repellent against the Tetranychus urticae Koch mite. This nanotechnological formulation offers a new option for the effective use of botanical repellents in agriculture, reducing toxicity, protecting against premature degradation, and providing effective pest control.

玉米醇溶蛋白纳米颗粒作为旨在实现可持续农业的植物驱避剂的生态友好载体系统

植物驱避剂是减少合成农药使用以及土壤和水土资源污染的主要方法之一。然而，这些化合物在环境中的差的稳定性和快速降解阻碍了它们在现场的有效应用。玉米醇溶蛋白纳米颗粒可以用作生态友好的载体系统，以保护这些物质免于过早降解，提供所需的释放特性并减少对环境和人类的毒性。在这项研究中，我们描述了负载香茅精油（香叶醇和R的主要成分）的玉米醇溶蛋白玉米醇溶蛋白纳米颗粒的制备和表征-香茅油）。还评估了纳米颗粒对靶标和非靶标生物的植物毒性，细胞毒性和昆虫活性。植物制剂在纳米颗粒中显示出高的包封效率（> 90％），良好的物理化学稳定性以及对驱虫剂抗紫外线降解的有效保护。细胞毒性和植物毒性测定表明，植物驱虫剂的包封降低了它们的毒性。驱避活性试验表明，含有植物驱虫剂纳米颗粒对高度斥二斑叶螨科赫螨。这种纳米技术配方为在农业中有效使用植物驱避剂，降低毒性，防止过早降解以及提供有效的害虫控制提供了新的选择。
