Abstract: The present invention relates to a method of selectively spraying an area of a cultivated field (10) with an agriculture spraying vehicle. The vehicle comprises a spraying equipment (200) having at least one imaging system (210), and at least one trailing spray bar (300) comprising a plurality of electromechanical nozzles (310) spaced apart from each other by a constant pitch distance. The plurality of electromechanical nozzles (310) includes a corresponding plurality of nozzles (314) and of electromechanical valves (312). The agriculture spraying equipment (200) further comprises a control unit (220) including a processing unit to control the electromechanical valve (312) of each electromechanical nozzle (310).

Abstract: The invention concerns a method using a robot for an automatic treatment of a weed, the method comprises steps of capturing images of said weed with a camera on said robot; determining with said images a distance between the weed and a second vegetable organism; and selecting a treatment tool of said robot for a treatment of the weed from a group of treatment tools as function of said distance. The invention further concerns a robotic vehicle for carrying out the method for an automatic treatment of a weed.
