Research advances of the drift reducing technologies in application of agricultural aviation spraying

With the gradual deterioration of ecological environment and increase in requirements for quality modern life, use pesticides is bound to develop towards higher pesticide utilization less environmental pollution, low-volume spraying agricultural aviation operation combined with Drift Reducing Technologies (DRTs) may be a useful way achieve this goal. Based on an analysis spray drift mechanism primary factors influencing aerial spraying, previous research DRTs were reviewed summarized, it was found that can effectively reduce pollution caused by reducing amount improving control effect pesticides, included electrostatic technology, adjuvant, air-assisted nozzles variable-rate technology. And according current status, some suggestions countermeasures droplet put forward from aspects strengthening plant protection Unmanned Aerial Vehicle (UAV) adopting reasonable methods. It hoped provide reference guidance enterprises’ product improvement users’ practical operation, play advantages precision fully.
