(2) in the natural environment of illumination, high temperature, drying, the water in the soup is easy to evaporation, causes medicament only to remain in crop surface, comes off and loses efficacy from crop easily after photodissociation and the drying easily;
(3) mist droplet particle size of conventional spraying is bigger, reaches 200～600 μ m, causes being sprayed onto the lip-deep soup of crop or target and runs off easily.
(4) for a long time, the single and frequent use of pesticide species makes biological target grow with each passing day to the resistance of medicament itself, is unfavorable for the prevention and control to pest.
