Spreading of agricultural sprays on plant surfaces is a significant task as it helps decrease pesticide usage and thereby reduces the risk of environmental pollution. Here, we report a method of increasing the spreading of herbicide benquitrione droplets on superhydrophobic surfaces through its selective dynamic self-assembly with amino pillar[5]arenes. Supramolecular interaction such as host–guest interaction was utilized for the complete diffusion of benquitrione over the hydrophobic plant surface. Furthermore, molecular dynamics simulations were used to verify that AP5A improved the spreading of benquitrione droplets on superhydrophobic interfaces. Moreover, complexation of benquitrione did not affect its biological activity. The present work provides a new method for improving the utilization rate of pesticides and reducing pesticide use.

通过基于柱[5]芳烃的主客体化学反应，苯并三酮液滴在超疏水性叶上的扩散。

将农用喷雾剂散布在植物表面是一项重要的任务，因为它有助于减少农药的使用，从而降低环境污染的风险。在这里，我们报告了一种通过具有氨基支柱[5]芳烃的选择性动态自组装来增加除草剂苯奎三酮液滴在超疏水表面上扩散的方法。超分子相互作用（例如宿主与客体的相互作用）被用于使苯奎三酮在疏水性植物表面上完全扩散。此外，使用分子动力学模拟来验证AP5A改善了苯奎三酮液滴在超疏水界面上的扩散。此外，苯并三酮的络合不影响其生物学活性。本工作为提高农药利用率和减少农药使用提供了一种新方法。
