Electrodynamic Spraying and the Control of Pests of Agricultural Crops1

A new method of agrochemical application, electrodynamic spraying, has recently been developed by ICI. It combines the convenience of ULV application with a very high order of accuracy. Using an electric field effect, the spray droplets are charged so that they deposit onto both exposed and hidden surfaces of the target plant Since the introduction of the first commercial machine, the « Electrodyn >> sprayer, which was primarily designed for use in cotton, further developments have taken place and systems are now being evaluated for the control of insects, diseases and weeds in a variety of crops.
