Effect of carbon chain length of cationic surfactants on regulating droplet behavior on peanut leaves.

Background: Droplet rebound on superhydrophobic leaves during pesticide application significantly increases pesticide waste and decreases application efficiency. An appropriate surfactant is crucial for suppressing droplet rebound and enhancing wetting and spreading on leaf surfaces.

Results: The rebound, wetting and spreading behaviors of cetyltrimethylammonium bromide (CTAB) series of surfactants with varying different carbon chain lengths (n = 6-16) were evaluated on peanut leaves.

ROS-responsive modified chitosan oligosaccharide nanocapsules for improving pesticide efficiency and intelligent release.

Background: Some traditional pesticide formulations are inefficient, leading to excessive use and abuse of pesticides, which in turn effects environment. Intelligent release pesticide formulations are ideal for improving pesticide utilization and persistence while reducing environmental pollution.

Results: We designed a benzil-modified chitosan oligosaccharide (CO-BZ) to encapsulate avermectin (Ave).
