Research Abstract |
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.
