Popis: Comparative measurements of leaf surface wetness duration were made by a beta‐ray gauge and an electronic sensor under various wind conditions in the laboratory. Under certain conditions, surface wetness duration measured by the electronic sensor was about 35 minutes shorter than that by the beta‐ray gauge. Fair agreement between the sensors at low wind speeds was achieved when the wire grid of the electronic sensor was mounted on a microscope cover glass. Realistic leaf surface wetness duration can be obtained with a beta‐ray gauge as it utilizes the attached leaf surfaces rather than artificial ones used on the electronic sensor.
