Construction of Iron‐Modified Lignin‐Based Nanomicrocapsules for Enhancing the Functionality of Natural Product–Based Pesticides

To address the issue of low pesticide utilization owing to poor dispersibility, low leaf surface adhesion, and poor transport within plants, this study exploits electrostatic interactions between sodium lignosulfonate (SL) and dodecyltrimethylammonium chloride (DTAC) to induce self-assembly, followed by iron ion (Fe
