A control system is disclosed for an agricultural implement, such as an agricultural sprayer, used to dispense a product to the ground wherein the dispensing units for the product are provided with control valves that can reduce the flow rate of product through selected dispensing units to zero. By controlling the rate of flow through the dispensing units, overlap of the application of the product to the ground can be substantially eliminated. In alternative embodiments of the invention, the control mechanism can receive data from a remote source, such as a central controller or another implement operating in the field, to define where the product needs to be applied to the ground. The application of the product can also be controlled through or in conjunction with a prescription map. Preferably, each dispensing unit is provided with a control valve operably associated with the control system so that each dispensing unit can be independently controlled to provide a variable flow rate of the product to the ground.

1. A method of applying agricultural product to the ground from an agricultural implement having a plurality of transversely oriented product dispensing units from which said agricultural product is dispensed and a control system for controlling a rate of product flow through said product dispensing

1. A method of applying agricultural product to the ground from an agricultural implement having a plurality of transversely oriented product dispensing units from which said agricultural product is dispensed and a control system for controlling a rate of product flow through said product dispensing units, comprising the steps of: controlling the rate of product flow through at least one of said product dispensing units according to whether said product dispensing units are overlapping product on the ground that had previously been dispensed. 2. The method of claim 1 wherein said controlling step includes the step of reducing said rate of product flow to zero for any of said product dispensing units that overlap a path of product on the ground that had been previously dispensed. 3. The method of claim 2 further comprising the step of: receiving data indicative of prior application of said product to the ground from a remote source. 4. The method of claim 3 wherein said remote source is a second agricultural implement working in conjunction with said first agricultural implement. 5. The method of claim 2 wherein said data is obtained from a prescription map inputted into said control system. 6. The method of claim 5, wherein said prescription map is received by said control system from a remote source.
