Abstract: An agricultural device includes a boom having a supply line for transporting liquid product and nozzles along the boom, each nozzle operatively connected to the supply line. A liquid product supply is connected to the supply line for supplying the liquid product to be sprayed. A pressure regulation unit includes a nozzle controller for controlling opening and closing of a nozzle. A speed detector measures speed of the device. The pressure regulation unit and/or the nozzle controller calculate nozzle timing data for each nozzle including a spraying frequency and a maximum closing time. The speed is provided to the pressure regulation unit and/or the nozzle controller for calculation of nozzle operation data. The nozzle controller operates each of the nozzles based on the calculated nozzle timing data and the maximum closing time is not exceeded to obtain a homogeneous spraying of the liquid product over a surface of a field.

Abstract: A system for treating plants, in particular in agriculture, comprising a spray boom (RP) provided with a plurality of spray nozzles (BPi) supplied by a spray control device, and comprising a set of cameras (CAk) capable of capturing images of an area to be treated, a digital processing device capable of analyzing the images captured by the camera, identifying plants to be treated and applying commands to the spray control device with a view to selectively spraying a product on plants to be treated, each camera (CAk) being capable of capturing images of the crop area.
