Description
Zhouming Gao and co-authors present a 2025 study of how spray droplets land on crop leaves. How a droplet spreads, sticks, or splashes decides whether pesticide coats the leaf or is wasted. Leaves curve and tremble in the field, and those motions were rarely studied together with impact speed.
Using high-speed cameras, the team varied impact energy, leaf curvature, and vibration frequency one at a time. More curve made spreading lopsided, wider in one direction and narrower in the other. Hard hits spread faster but splashed more. At the leaf's resonant shake, around 40 to 50 cycles per second, spreading and splashing both peaked. A fitted model ranked impact energy first and vibration second. The authors give a speed ceiling for practical spraying.
