Description

Efficient flight control auxiliary agent and preparation method and application thereof
Technical Field
The invention relates to the technical field of pesticide auxiliary agents, and particularly relates to a high-efficiency flight control auxiliary agent and a preparation method and application thereof.
Background
China is a big agricultural country, and modern agricultural production is a large-scale and integrated production mode. At present, the modern automatic or semi-automatic production mode is used. At present, the unmanned aerial vehicle is used for preventing and treating diseases and pests in agriculture and forestry, and can also be called aerial plant protection, namely flying prevention for short. In the past, the agriculture and forestry operation production mainly depends on each farmer to prevent and control the diseases and insect pests, and the efficiency is not high. At present, large-scale agriculture and forestry have shown certain development situation, and the production mode taking farmers as units is changing to the modernized agricultural production mode of large-scale, group, large-scale and automation in the past with small area. The flight control plant protection has important scientific research value and implementation and application significance at present.
However, the main problems of the current flight control aids are that: 1) the product is unstable, the problem of layering/precipitation is easy to occur in the storage process, the prevention and treatment effect is poor, and even a spray head can be blocked in serious cases; 2) fog drops are easy to drift in the spraying process, harm to surrounding crops, people and livestock can be caused, the utilization efficiency of pesticides is reduced, the drift phenomenon is mainly reduced by adding an anti-drift agent at present, but the dispersion of liquid medicine can be influenced by adding the anti-drift agent; 3) the applicability of the flight control adjuvant to pesticides, a flight control adjuvant which has good solubilization, stability, volatilization resistance and absorption and permeation promotion to common pesticides on the market is not available at present, and the flight control adjuvant needs to be specially prepared according to different pesticide types and types, but more than one pesticide can be applied to field control at present, and if the flight control adjuvant needs to be prepared separately for each pesticide, inconvenience is caused, popularization is not facilitated, and application is limited; 4) at present, non-flight control plant protection in China is mainly realized by a small unmanned aerial vehicle, the small fixed wing aircraft can not be used for spraying in farmland areas such as America, Canada and the like, the drug-loading capacity of the unmanned aerial vehicle is small, so that the liquid medicine has the characteristics of low dilution multiple, high concentration and small spraying amount, which provides higher requirements for the release drift property of the flight control auxiliary agent and the stability of the liquid medicine under high concentration,

Has good drift resistance and volatility resistance. However, the components are mainly polyether and polyester components, so that the stability of the auxiliary agent is insufficient while the drift resistance and volatility are improved.
CN108935459A discloses a modified vegetable oil flying prevention aid, wherein modified rosin oil is adopted, the layering or precipitation phenomenon in the storage process of the flying prevention aid is improved, the liquid medicine fog drop performance is improved, but precipitation can still be generated in water with high hardness.
CN109644998A discloses a flying prevention aid, which uses fluorocarbon surfactant, although the specific gravity and droplet particle size of the liquid medicine are improved, it has better anti-drift property. But the use of fluorocarbon surfactants can have undesirable effects on some crops. And if the fluorocarbon surfactant is excessive, serious potential safety hazard exists.

Application example 1Stability test
The emulsion was diluted 100 times and placed in a measuring cylinder with a plug and the stability of the emulsion was evaluated in terms of the time for which oil slick, separation, foaming, suspended matter, or clouding occurred, in accordance with GB/T1603-2001. The evaluation criteria are as follows:
Figure BDA0003725906350000071
in addition, conditions were also varied and tested at different pH (pH adjusted with acetic acid or sodium carbonate), and stability in hard water and after heating. Wherein, the hard water is prepared by standard hard water with calcium carbonate/magnesium content of 342mg/L (in the embodiment, the standard hard water is used for replacing tap water) when preparing the flight control auxiliary agent; the heating stability is the time for which the flying preventive auxiliary agent can be observed to be stable in a water bath condition at 60 ℃. The results are shown in table 1 below:

General conditions pH=6.5 pH=8.4 Hard water Heating of
Example 1 A A A B A
Example 2 A A B C C
Example 3 A B B B A
Example 4 A A A B B
Example 5 A A A B A
Fig. 1 to 5 are photographs of examples 1 to 5 respectively, which were kept under conventional conditions (25 ± 2 ℃, 60 ± 5% RH), pH6.5, pH 8.4, hard water (calcium carbonate/magnesium content of 342mg/L), and heat (60 ℃) for the same time. Wherein the standing time under the conventional condition is 10d, the pH value is 6.5, the pH value is 8.4, and the standing time under the hard water condition is 3 d; the heating condition standing time is 24 h.
As can be seen from the results of Table 1 and FIGS. 1-5, the flight control aid emulsions prepared according to the present invention are stable, and maintain a satisfactory degree of stability under a wide range of pH conditions, as well as hard water, and heating conditions. Wherein, the preparation example 2 adopts polyethylene glycol diglycidyl ether with shorter chain segment, which causes the hydrophilicity of the intermediate chain of the Gemini surfactant to be insufficient and the stability of the auxiliary agent to be slightly insufficient.
