1. A method for sequencing the application of electrical power to a plurality of electromechanical dispensing devices comprising:
- determining the number of dispensing devices;
determining a rate of application of electrical power to the electromechanical dispensing devices;
determining an operating time for applying electrical power to the electromechanical dispensing devices;
dividing the plurality of electromechanical dispensing devices into a plurality of groups;
determining a sequence time delay for actuating the electromechanical dispensing device groups by dividing the rate of application of electrical power by the number of electromechanical dispensing device groups;
generating command data in response to the rate of application of electrical power and operating time;
sending the command data to a first set of sub-controllers;
waiting a time interval equal to the sequence time delay for actuating the electromechanical dispensing device groups;
sending the command data to an additional set of sub-controllers, there being a sub-controller associated with each electromechanical dispensing device and a set of sub-controllers associated with each electromechanical dispensing device group; and
repeating the waiting step and the sending the command data to an additional set of sub-controllers step until all sets of sub-controllers have received command data;
each sub-controller applying electrical power to an associated electromechanical dispensing device in response to receipt of the command data.

Abstract
A method of controlling the application of power to a plurality of metering devices in a pesticide dispensing system permits operator controlled designation of row numbering, row-specific dispensing quantity of both seed and pesticide, and accurate records of starting and stopping times and locations. The method also permits operation of a large number of dispensing devices with a normal electrical system capacity by controlling the application or sequencing of power, the maximum power required by the system can be reduced at maximal speed and efficiency.
