Electrostatic pesticide spraying for fruit trees to deal with the Positive List System and to ensure the food safety

采用静电喷雾法和常规喷雾法对日本梨树进行了锈病防治试验。结果表明，EPS法能有效地控制病害。这意味着EPS方法可以减少对目标区域产生预期效果所需的农药量和控制成本。研究还表明，利用接地导电网可以屏蔽带电农药液滴，以防止农药的漂移危害。接地导电网放置在目标作物和非目标作物之间。从EPS喷嘴喷出的不粘附在目标作物上的荷电漂移农药被吸引到网上。因此，减少了粘附在非目标作物上的农药量。

The pesticides were sprayed by electrostatic pesticide spraying (EPS) and the conventional spraying methods to Japanese pear trees to control a disease (rust). It is shown that the EPS method control the disease effectively in comparison with the conventional method. This means that EPS method can reduce the amount of pesticide needed to produce the desired effect for the target area and the control cost. It is also shown that charged pesticide droplets can be shielded by using a grounded conducting net to prevent the drift hazard of pesticides. The grounded conducting net is placed between the target and non-target crops. The charged drifting pesticide, which is sprayed from the EPS nozzle and does not adhere to the target crops, is attracted to the net. Consequently, the amount of pesticide adhering to the non-target crops is reduced.
