With the increasing variety of pesticides, as well as all environmental protection of the importance Tigao pesticide utilization, reduce pesticide residues might become a social Guan Zhu's focus, then, Ruhe can improve the utilization of pesticides do?
    First to improve the mechanical properties of sprayed manually change the status of a single spraying components, and promote the upgrading of manual sprayers. Spray atomization quality is the decisive factor, directly affects the deposition of pesticides in crop distribution. Relationship between droplet density is an important factor to control effects. The same amount of liquid, if the droplet size by half, from 8 times increased the number of droplets. Therefore, the relevant government departments and enterprises to develop an ideal replacement of some aerosol species.
    Second, the implementation of low-volume application techniques to reduce the amount of liquid present Mushi. Plant leaf surface can be attached to the pesticide droplet is limited, when the spray volume exceeds a certain limit, leaves a small pool into big droplets and the droplet will roll off, lost, but the leaf attached to a sharp reduction of pesticide . Developed countries are generally controlled spray volume per hectare in the range of 100-300 liters, less than our spray volume per unit area of 1 / 3, so the loss was minimal, higher utilization of pesticides.
    Third, we must conduct extensive training in pesticide application technology to enable farmers to master science and application methods. Mainly the farmers to understand the following aspects: 1. As is the Hand Pressure Sprayer to spray way to go through a distance of 30 cm or more can completely atomized, so spraying pesticides, they must maintain a distance from the nozzle and the crop 30 cm above the surface to avoid the spray nozzle close to the crop. 2. In the use conical fog nozzle spray operation should be about to change sides along the direction "Z" shaped cross-spray habits, to take the wind side "Z" shaped spray, ensure application personnel location is drug-free zone. At the same time, should be gradually replaced with a fan beam cone mist nozzle fog nozzle, spray to one side parallel to the marching method to improve the uniformity of pesticides. Motorized sprayer takes the form of pneumatic atomization, the farther away from the nozzle, the droplet the more detailed, the general level of spray rate of 8 meters. In the spraying of pesticides, to make full use of the effective spray width, spray to drift superposition method to improve work efficiency and control effect, to avoid the targeted spray. 3. Operation should be determined in accordance with wind direction to point the nozzle (spurt), machine hand routes (direction) and field operations order (beginning to) principle, so playing in the wind as far as possible consistent with, not against the wind operation. 4. To the object under control and crop disease and insect pests at different growth stages and parts, flexibility nozzle height and angle. Currently, farmers often used, along the direction of the spray is about cross-ways, will reduce the spray rate, the formation of turbulence, resulting in uneven distribution of droplets, but also the entire operating environment is filled with pesticides, people are very vulnerable to pesticide poisoning should be avoided.
