Problems solved by technology

[0014] In order to solve the defects in the prior art that the droplet spectrum range is wide, the specific gravity is too small, the sedimentation speed is slow, easy to drift, easy to evaporate, the deposition amount of the droplet is small, the penetration is poor, and the pesticide reduction in the narrow sense cannot be realized. The purpose of the invention is to provide a plant protection drone aerial pesticide application adjuvant that reduces the amount of pesticides used, its preparation method and application

Embodiment 1

[0054] The weight of the raw material and the particle size of the condensed nuclei (unit μm) of the plant protection UAV aerial pesticide application adjuvant (abbreviated as the anti-flying adjuvant) for reducing the amount of pesticide usage described in Examples 1 to 7 are as shown in Table 2 below Show.

[0057]

Embodiment 3

[0126] Example 3 The particle size of the condensed substance is controlled at 2 μm, so that the corresponding droplet size is ≤50 μm. Outdoor plant protection drones apply pesticides by air, and the temperature, humidity, wind direction, and wind force are greatly affected, and the drift of the droplets is large. The interference ability of the crosswind is weak, the evaporation amount is large during the movement of the fog droplets, and the settlement is slow. But embodiment 3 meets biological optimal particle size, has excellent control effect to the adults of flying in grassland locust extermination and closed space (such as steel structure greenhouse), is suitable for plant protection UAV aerial spraying under certain conditions, to Reducing the use of pesticides has an important auxiliary effect.

[0127] Thus it is proved that the scientific ratio of the components in the plant protection UAV aerial pesticide application adjuvant prepared in Examples 1 to 7 to reduce t...

Abstract

The embodiment of the present invention relates to an aviation pesticide application adjuvant and its preparation method and application, belonging to the field of pesticide adjuvants, including the following raw materials in mass percentage: 0.5-3.0% of large molecular weight hyaluronic acid, 0.05-1.0% of small molecular weight hyaluronic acid %, fluorocarbon surfactant 1-5%, soybean lecithin 1-15%, coagulation nuclei substance 1-10%, water-soluble vitamin E 1-10%, emulsifier 1-15%, suspending agent 0.05- 5%, the remaining water is 100%; the particle size of the coagulation nuclei is 2-10 μm, the molecular weight of the high-molecular-weight hyaluronic acid is 400KDa-8000KDa, and the molecular weight of the low-molecular-weight hyaluronic acid is 8KDa-30KDa. By precisely controlling the particle size of condensation nuclei, adjusting the droplet spectrum of the spray liquid, reducing the drift of the droplets, increasing the deposition rate and adhesion effect of the droplets, the addition can effectively reduce the amount of pesticides used by 30-70%.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, in particular to an aerial pesticide application adjuvant especially suitable for plant protection drones capable of reducing the amount of pesticides used, as well as its preparation method and application. Background technique [0002] The information disclosed in this Background section is only for enhancing the understanding of the general background of the present invention and should not be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Four departments including the Ministry of Education, the Ministry of Science and Technology, the Chinese Academy of Sciences, and the National Natural Science Foundation of China jointly launched the "10,000 Scientific Problems" collection activity in 2007, among which the dose delivery of pesticides was among them. [0004] During th...
