This study utilizes cellulose acetate (CA) nanoparticles at low concentrations (0.5 wt %) to create stable oil-in-water Pickering emulsions. Rheological and microscopic analyses reveal interconnected NP aggregate networks between droplets, demonstrating “double” yielding behavior. The emulsions are proven effective for agriculture formulations by incorporating abamectin (Abm) and a plant-growth-promoting microbe (PGPM). Sustained release of Abm and enhanced viability of PGPM after 70 days of storage highlight the emulsions’ potential for practical agricultural applications. Overall, this research establishes CA nanoparticles as a sustainable Pickering emulsifier, offering a versatile platform for delivering various agriculture cargos.
