A sprayer, particularly for hand-held or vehicle-borne agricultural use, has a rotatable sprayhead having a liquid dispersing surface in the form of disc, dish or cup, a rotatable electrode spaced from the outer edge of said surface by a gap, means for supplying liquid to the liquid dispersing surface, connections for the poles of a source of electrostatic potential to apply one pole of the source to the electrode and to apply the other pole of the source to at least the outer edge of the surface to apply the potential of the source across the gap, and means to rotate the surface and the electrode to disperse liquid supplied to the surface as a charged spray. The potential may be applied to the outer edge via the liquid if conductive or via a suitable conductive path in the sprayhead. |
