Effect of adhesion force on the height pesticide droplets bounce on impaction with cabbage leaf surfaces

Abstract

The relationship between adhesion force and the height drops containing Difenoconazole-loaded mesoporous silica nanoparticles (DF-MSNs)/Tween 80 bounce on cabbage leaf surfaces was investigated as a function of Tween 80 concentration. The adhesion force of a pesticide droplet on cabbage leaf surfaces was assessed using a high-sensitivity microelectromechanical balance system and the impact behavior was recorded with a high-speed camera. The height droplets bounced decreased with increasing adhesion force, with a negative correlation between height of the bouncing drops and adhesion force. Although droplets containing ≥ 0.06% Tween 80 adhered to the cabbage leaves, the retraction height was still observed to decrease as adhesion force increased. The experimental results indicate that for cabbage leaf surfaces, the adhesion force has a significant effect on the height drops bounce. The results provide new insights into how researchers can screen for formulations for hydrophobic target crop and how to increase spray adhesion to difficult-to-wet crop leaf surfaces.
