ABSTRACT:
Spraying apparatus for spraying liquid pesticides on to crops growing in the ground includes a plurality of electrostatic spraying devices mounted on a boom which can be mounted on a powered vehicle such as a tractor or an aircraft. Each spraying device includes a spray-head having an at least electrically semi-conducting surface charged to a potential of the order of 1-20 kilovolts, a field intensifying electrode mounted adjacent the spray-head surface and being so sited relative to the spray-head surface that the electrostatic field thereat causes pesticide liquid delivered thereto to atomize without substantial corona discharge to form electrically charged particles.
