摘要: Conventional pesticides face persistent challenges of instability, rapid wash-off, and resistance, while synthetic nanocarriers often suffer from poor degradability, scalability barriers, and regulatory uncertainty. Phytochemical self-assemblies (Phyto-SANs), defined in this review as carrier-free nanoassemblies constructed entirely from plant-derived metabolites, provide a carrier-free and eco-compatible alternative, spontaneously organized from natural metabolites such as polyphenols, alkaloids, and saponins through hydrogen bonding, π–π stacking, hydrophobic, and dynamic covalent interactions. These nanoscale architectures integrate intrinsic bioactivity with structural robustness, achieving enhanced rainfastness, UV resistance, and multi-stimuli-responsive release while potentially contributing to plant defense modulation. Drawing on biomedical precedents, this review establishes a mechanism-centered framework linking supramolecular interactions with agricultural functionality, encompassing stability, interfacial transport, responsive release, and defense co-activation. It further outlines translational priorities in green manufacturing, biosafety evaluation, and regulatory readiness to guide large-scale adoption. Collectively, Phyto-SANs represent an emerging conceptual framework of phyto-mediated protection—where plant-derived molecules are re-engineered through supramolecular chemistry to achieve intelligent, sustainable, and field-ready crop protection.
