A guard ring for controlling size of a sprinkler column of liquid streams from a sprinkler head in an electrostatic spraying system is connected through a large resistor to ground. This provides an interaction between the liquid sprinkler column and the ring which tends to constrict the size of the column of sprinkled liquid and reduce the likelihood of the column spreading out and engaging sides of a receptacle used for receiving the liquid. The ring does not require power.
