Sensor-based detection of leaf roll sickness on grapevines directly in the field
The leaf roll disease of the grapevine is a viral disease that spreads worldwide and causes great economic damage. Since the disease cannot be treated directly in the field up to now, prevention is crucial in virus management: Infested sticks must be recognized and cleared early on. However, many plants develop only mild symptoms or no symptoms. The JKI has tested a sensor-based early detection system for leaf roll disease in the field with the Fraunhofer Institute IFF, the Geisenheim University and the University of Hohenheim. With hyperspectral cameras and an adapted phenotyping pipeline, infected vines can be detected earlier than before and suitable measures can then be initiated.
