Utilizing nanotechnology for pesticide delivery can enhance their uptake and distribution in plants, thereby boosting efficiency. Fluazinam, a highly effective broad-spectrum fungicide with unique mode of action, is hindered by its poor systemic conductivity, limiting field control efficacy. In this study, fluazinam-loaded nanocapsules were developed, which exhibited significantly higher inhibitory activity against various Phytophthora species compared to the commercial suspension concentrate. Notably, demonstrated pronounced effects on reducing ATP content capsici effectively controlled pepper blight cucumber downy mildew. Tracking fluorescein isothiocyanate (FITC) fluorescein-labeled fluazinam revealed presence roots seven days after treatment. High-performance liquid chromatography (HPLC) analysis confirmed easy absorption transport plants. Moreover, treatment increased expression two exocytosis genes, FACP RABF2a, tissues.

The development of intelligent multifunctional nanopesticides featuring enhanced foliage affinity and hierarchical target release is increasingly pivotal in modern agriculture. In this study, a novel cationic amphiphilic comb-shaped polymer, termed PEI-TA, was prepared via one-step Michael addition between low-molecular-weight biodegradable polyethylenimine (PEI) tetradecyl acrylate (TA), followed by neutralization with acetic acid. Using the emulsifier positively charged avermectin (AVM) nanoemulsion phase inversion emulsification process. Under optimal formulation, obtained AVM (defined as AVM@PEI-TA) demonstrated exceptional properties, including small size (as low 67.6 nm), high encapsulation efficiency (up to 87.96%), stability toward shearing, storage, dilution, UV irradiation. endowed AVM@PEI-TA pronounced thixotropy, so that droplets exhibited no splash bounce when they were sprayed on cabbage leaf. Owing electrostatic attraction leaf, showed improved leaf adhesion, better deposition, higher washing resistance contrast both its negatively counterpart emulsifiable concentrate (AVM-EC).
