ABSTRACT:
A tractor is equipped with a tool bar to which are attached a plurality of cultivators. Sensors are fixed by means of clamps and shanks located over the drill of the planted crop in such a manner that weeds growing above the height of the crop are detected. Once the weed is detected, a spray nozzle is activated and the weed is treated with herbicide. Weeds which are not taller than the growing crop are sprayed as the driver of the tractor manually activates spray nozzles to spray low lying weeds which he visually detects.
