2, conventional spray-on process prevention and elimination of disease and pests needs large water gaging, and water consumption reaches 450-900L/hm conventionally
2, and much away from water source and drought and water shortage area, conventional spray-on process is difficult to carry out or can not reaches desirable control efficiency.
3, it is short that conventional spray-on process makes the with medicament lasting period, is generally missible oil, aqua, wetting powder, suspending agent, aqueous emulsion etc. because conventional spray-on process makes the formulation of with medicament, has in the use certain defect:
(1) owing to adding the dilution of large water gaging, the concentration of liquid is very low, and surface tension is often larger, having the crop of wax coat or the lip-deep adhesiveness of target, wetability, permeability poor, is difficult to effectively enter in crop and target body, causes preventive effect poor;
(2) in illumination, high temperature, dry natural environment, the water in liquid is easy to evaporation, causes medicament only to remain in crop surface, easily photodissociation and dry after easily come off and lost efficacy from crop;
(3) mist droplet particle size of conventional spraying is larger, reaches 200-600 μ m, causes being sprayed onto the lip-deep liquid of crop or target and easily runs off;
(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.
