The invention relates to an inverted-U-shaped plant-spraying device that can maintain the plant between the two arms of the U. The device is characterised in that it includes a fan (1.1, 2.1) in the upper part of the U, which absorbs any drops that are not deposited on the plant, said fan including air outlets connected to air ducts (1.2, 1.3) which are located in the arms of the U and joined to ducts (5) conveying the liquid to be sprayed. In addition, the lower ends of the arms of the U are provided with upwardly oriented sprayers. The air ducts (1.2, 1.3) and the liquid-conveying ducts (5) are joined in the lower part of the arms of the U and the lower part of the centrifugal fan (1.1, 2.1) is provided with a mesh (7) that prevents leaves from the plant entering the fan. The front and rear parts of the U forming the plant-spraying device include a frame (8) that is intended to reduce the cross-section of the U and, consequently, increase turbulence, said frame (8) having strips of soft plastic provided with transverse cuts designed to reduce possible damage to the leaves of the plant (6). Moreover, the air ducts (1.2, 1.3) are not positioned facing one another so as to ensure better distribution of the material being sprayed onto the plant (6) and at least one outlet for the sprayed material is positioned at mid-height of both arms of the U and oriented towards the upper part of the arms of the U.
