Pesticide spray droplets can damage ecological environments and negatively affect biodiversity if they reach nontarget areas. Effective retention of pesticide on plant surfaces is an important challenge. In this study, a high-speed camera was utilized to visualize the bounce behavior different solutions rice leaf surfaces. We explored addition surfactants (SAAs) altered solution system prevent or regulate droplet behavior. Experimental results indicate that SAAs inhibit bouncing Additionally, water-in-oil (EO) emulsion not only significantly rebound superhydrophobic surface, but also quickly automatically spread maximize wetting area. Therefore, work effectively improves utilization pesticides reduces environmental pollution.
