摘要： A sprayer system (10) has a first liquid line (160) and a second liquid line (170), both in fluid communication a row. In an embodiment, the row has a first pulse width modulated (PWM) valve (191) in fluid communication with the first liquid line (160) and a second PWM (191) in fluid communication with the second liquid line (170). The PWM valves may both be connected to same nozzle (195) or they may be connected to separate nozzles. The PWM valves may be arranged in a common housing. In an alternative embodiment, each row has a three-way valve (193) in fluid communication with the first and second liquid lines (160, 170). The three-way valve (193) is in fluid communication with a PWM valve (191), which is in fluid communication with a nozzle (195). The sprayer system can be used to apply one chemical to an entire field through the first liquid line and selectively apply an additional chemical to individual locations in the field through the second liquid line.
