How to ensure that the pesticides are attached to the leaves of the crop? This depends on the atomization effect sprayed by the drone. The smaller the atomized particles are, the more medicine and water are saved, and the more uniform adhesion is. It is not easy to gather into water droplets and then drip to waste. Generally speaking, the atomized particles below 250 microns can achieve a better spraying effect. Large particles of liquid medicine are easy to gather and drop. Only when the atomized particles are small can they be uniformly attached to the surface of the insects to achieve the effect of contact to kill and prevention..

Currently, the plant protection drones on the market mainly use pressure nozzles and centrifugal nozzles. Generally speaking, the atomized particles of the centrifugal nozzle are smaller and the its size can be adjusted. The centrifugal nozzle technology whose atomized particle size can be adjusted below 250 microns is the best choice. These data can generally be seen in commodity parameters, so you can pay attention when choosing products.

Can it be sprayed evenly to make the target area be filled with medicine evenly?

At present, there are two main spraying techniques for plant protection machines on the market. One is constant spraying technology, and the other is variable spraying technology.

In AG drone spraying, UAVs need to turn when flying in a field, and turning is generally accompanied by deceleration. If it is a constant spraying technique, the flow rate will not automatically adjust as the flight speed drops, which may cause excessive drug loading on crops at the turning position of the ground edge, and result in phytotoxicity and waste of pesticides. With variable spraying technology, the flow rate can be reduced as the flight speed decreases, so as to ensure the equal dosage of each inch of farmland and good spraying effects.

Therefore, when choosing a plant protection machine, it is recommended to choose one with variable spraying technology. Generally speaking, you can judge from the parameter setting interface of the product. Manual drones generally do not use this technology. If the interface displays the set flow rate, there is generally no variable spray technology. Plant protection drones with variable spraying technology can generally be set the spraying amount per mu.
