Influence of Plant Leaf Moisture Content on Retention of Electrostatic-Induced Droplets

Agricultural electrostatic spraying can help to reduce the threat of pesticides to human health and the environment. However, the influence of the law of leaf water content on electrostatic spraying has not been studied. In this study, we used leaf water content as an evaluation index of electrostat...
