A device for the introduction of a liquid substance (3) into the trunk of a plant (2) comprises a sealed container (4) connected to one or more distribution ducts (8) by means of at least an outlet duct (5'). Along the circuit there are provided means to regulate (10a,10b) and means to detect (6) the flow rate of the substance towards truncated-cone injection needles (9) inserted into appropriate holes (19) in the plant's trunk. The method according to the invention involves the use of said device to allow the introduction of the treating substance into the layer of the xylem (23) involved in the ascending vascular circulation of the plant. <IMAGE>
