Scientific use of pesticides to control crop diseases and insect pests, is to ensure that agricultural production of high quality, high yield and efficient one of the important means. However, due to the current majority of rural areas in China is a diversified use of pesticides, can not be a scientific drug, not only caused a lot of waste of pesticides, but also led to human and animal poisoning, crop damage, resistance, anti-control, environmental pollution A series of problems, to the agricultural production and people’s lives caused great losses. In view of this problem, our scientists after years of research and the creation of “pesticide to spray” theory and application of technology, proved to be effective in pesticide crop precipitation rate from the original application method of about 30% to 60% Into the environment to reduce the amount of pesticide 1/2, saving pesticides 50% to 90%, about 90% of water conservation. Now several advanced application technology is described as follows:
           Low-volume spray technology refers to the unit area in the case of the same amount of application, the pesticide stock solution diluted with water, the amount of water is quite conventional spray technology 1/5 to 1/10. This technology is very simple to use, just the conventional spray machine large aperture spray into the aperture of 0.3 mm small aperture spray can be. The use of this technology can greatly improve the efficiency of operations, reduce pesticide loss, save a lot of water, significantly improve the control effect, effectively overcome the conventional spray to the greenhouse caused by wet damage. This technology, especially suitable for greenhouse and water shortage of mountain applications, welcomed by farmers.
          Electrostatic spraying technology in the spraying equipment, the installation of high-voltage electrostatic generating device, the operation through the high-voltage electrostatic generating device, so that droplets charged with spraying liquid in the crop leaves on the surface of a substantial increase in the effective utilization of pesticides to 90% Thus avoiding a large number of pesticides ineffectively into the farmland soil and atmospheric environment.
          “Pill Granulation” Application Technology This application technique is suitable for paddy field. For the use of paddy field water-soluble pesticide, the use of “pelleting” application of good technology. Only the processing of good pills evenly applied to the farm can be more than the conventional application method can improve the efficiency of ten times, and there is no pesticide drift phenomenon, effectively prevent the crop stems and leaves suffered phytotoxicity, and does not pollute the adjacent crop.

Recirculation spray technology to re-design of the conventional sprayer, spray parts on the opposite side of the installation of drug refluxing device, the deposition of drugs on the target plant is not collected after the withdrawal to the medicine box, so that pesticides can be recycled, Can greatly improve the effective utilization of pesticides, to avoid the ineffective loss of pesticides.

          The technology is mainly applied to the absorption of herbicides. The liquid is exuded from the surface of the drug roll by means of a drug roll, which is made of a foam material that absorbs the liquid, and the chemical roll is only accessible to the upper leaves of the weeds. This method of application, almost all of the chemicals applied to the surface of the target plant, will not occur thawing and dripping, pesticide utilization can reach 100%.
          Electronic computer application technology, the United States and other countries, the computer control system has been used on the orchard sprayer, the system through the ultrasonic sensor to determine the shape of fruit trees, so that pesticide spray characteristics are always based on changes in the shape of fruit trees and automatically adjust. Electronic computer control system for spraying, can greatly improve the efficiency of the operation and the effective utilization of pesticides, the emergence of this new technology represents the development of pesticide use technology.
