And the use of pesticide has also brought environmental pollution's problem, at the in-process of spraying the pesticide, for avoiding the pesticide in the staff direct contact air, generally adopt plant protection machinery to replace artifical application of medicine now, like plant protection unmanned aerial vehicle.

In the air spraying operation process of an airplane carried on the airplane or on the ground, due to the action of wind, the process definition position of liquid drops which do not reach a target area drifts, pesticides cause environmental pollution through plants, air or water, wherein pesticide chemical components in the plants and various animals gather, part of toxic components are enriched in human bodies through food chains, and pesticide drift in the air can enable local residents, livestock, terrestrial and aquatic ecosystems to directly or indirectly contact liquid medicines. In the past decades, many scholars have demonstrated that pesticides cause a significant portion of their environmental pollution due to drift of pesticides in the air.

In addition, pesticide drift influence factors comprise droplet size, droplet speed, physical and chemical components, environmental humidity and temperature, the height of a fog rod and a sprayer, and drift can be reduced to a certain extent by adopting an air supply technology, electrostatic spraying and a windshield. It can be concluded that the main external environmental factors of pesticide drift in the air, except wind power, are ambient humidity and temperature, and therefore, the drift influence of the external environmental factors, namely wind power, humidity and temperature, on pesticide spraying needs to be weakened.
