Star polycation (SPc) was an efficient nanocarrier of insecticides and fungicides. However, whether it could serve as an herbicide nanocarrier needs further study.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n \n Here, we evaluated the nanoformulation, permeability, and herbicidal efficacy of SPc assembled with herbicides. Results showed that SPc could spontaneously assemble with each of the three herbicides\n via<\/jats:italic>\n electrostatic interactions. Only mesotrione technical concentrate (TC) and formulation (FM) could be effectively nanosized by SPc, while the particle sizes of atrazine and quizalofop\u2010p\u2010ethyl showed only a marginal decrease. Mesotrione self\u2010assembled with SPc mainly through specific hydrogen bonding, achieving a loading capacity of 38.8%. SPc reversed the zeta potential of mesotrione from negative to positive (with a negligible change in absolute value), reduced the contact angle of TC and FM by 10.5% and 7.8%, respectively, increased the retention on leaves by ranges of 24.3%\u201365.7%, and significantly enhanced the foliar absorption of mesotrione by 12.4% after treated for 7\u2009days. Compared with the SPc\u2010free treatment, the fresh weight inhibition rates of mesotrione TC\u2009+\u2009SPc and FM\u2009+\u2009SPc against\n Digitaria sanguinalis<\/jats:italic>\n ,\n Setaria viridis<\/jats:italic>\n , and\n Amaranthus retroflexus<\/jats:italic>\n were increased by ranges of 17.24%\u201354.05% and 31.32%\u201339.60%, respectively. The nanosized mesotrione caused no influence on the maize biomass even at 1.5 times the recommended dose (562.5\u2009mg\/L).\n <\/jats:p>\n <\/jats:sec>\n \n CONCLUSION<\/jats:title>\n This study establishes SPc as a high\u2010performance delivery platform for enhancing the bioavailability of certain herbicides, and offers a theoretical basis for the application of SPc as a tank\u2010mix adjuvant in weed management. \u00a9 2026 Society of Chemical Industry.<\/jats:p>\n
