| Abstract: | It is of great significance to proceed variable rate spray (VRS) according to the requirement of crops for saving pesticide and protecting environment. A hand-push sprayer of type 3WY-A3 was tested with the VRS system on real-time mixing pesticide. The VRS system includes a mixing pesticide device, a differential pressure (DP) flow meter, a flow control valve and control hardware and software. The experimental results showed that the pesticide flow range was from 0.1 to 0.9 mL/s with control accuracy of ±5%. |
