WEED CONTROL SYSTEM

A weed control system includes an autonomous work device, and the autonomous work device includes driving means configured to move the autonomous work device, sensor means configured acquire a sensor signal from the environment of the autonomous device, and a control circuit configured to control the driving means to navigate the autonomous work device in the environment. The weed control system includes at least one disposable releasable shading plate arranged on a release mechanism of the autonomous work device. The control circuit is configured to detect plants in the environment based on the acquired sensor signal, to determine whether a detected plant is a target plant, and in case a detected plant is a target plant, to control the release mechanism to release the releasable shading plate onto the location of the detected target plant.
