Description
Technical Field
The invention relates to the technical field of pesticide preparation, in particular to a high-efficiency pesticide for preventing and treating field red spiders and a preparation method thereof.
Background
Red spider, also known as Raphina gossypii, belongs to the order Arabia, Tetranychidae of the Araceae. The red spiders live through the winter at the positions of cracks of plant branches, fallen leaves, soil seams of shallow soil layers around roots and the like mainly by eggs or fertilized female adult mites. The temperature rises again in the spring of the next year, and the overwintering female adult mites start moving to damage when the plant starts to grow buds. After the leaves are spread, the leaves are turned to be damaged, firstly, the damage is caused on two sides of the main vein on the back of the leaves, and the main vein gradually spreads over the whole leaves from a plurality of small groups. When the occurrence amount is large, the plant draws wires and crawls on the surface of the plant, and the plants are spread by wind. In general, the full growth period is reached in the middle of 5 months, the peak growth period of the whole year is 7-8 months, and the harm is most serious from the late 6 months to the early 7 months.
As is known from the above, red spiders are extremely harmful to field crops. Therefore, farmers often use insecticides to control field red spiders and other pests, but currently marketed insecticides have poor effect on controlling red spiders and short duration of efficacy, so that under the situation, a novel efficient insecticide for controlling field red spiders and a preparation method thereof are provided, and the technical problem to be solved by technical personnel in the field is urgently needed.
Disclosure of Invention
Aiming at the problems, the invention provides a high-efficiency pesticide for preventing and controlling field red spiders and a preparation method thereof, which are used for solving the technical problems in the background technology.
In order to achieve the purpose, the invention adopts the following technical scheme:
the efficient pesticide for preventing and treating the field red spiders comprises the following raw materials in parts by weight: 45-55 parts of composite suspending agent, 5-7 parts of compound sodium nitrophenolate, 7-10 parts of diclofen, 8-15 parts of citrus extract, 4-8 parts of thiamethoxam, 20-30 parts of etoxazole, 1.5-2.5 parts of synergist, 2.6-3.2 parts of dispersant, 1.2-1.6 parts of wetting agent and 3.2-3.8 parts of emulsifier;
the composite suspending agent is prepared by mixing and stirring fluazinam and abamectin suspending agent according to the mass ratio of 9-15: 0.8-1.2.
Furthermore, the synergist is one of gamma-aminobutyric acid and emamectin benzoate.
Wherein, the synergist and the avermectin suspending agent are mutually cooperated, so that a large amount of chloride ions enter nerve cells of red spiders, the cell function is lost, the nerve conduction is disturbed, the larvae stop feeding immediately after being contacted, the irreversible paralysis is generated, and the highest lethality rate is reached within 3-4 days. Because the red spider is tightly combined with soil and is not leached, the red spider is not accumulated in the environment, has long-term residual effect on crops after being applied, can kill the red spider for the second time, and is rarely influenced by environmental factors such as wind, rain and the like.
Furthermore, the dispersant is selected from one of triethyl hexyl phosphoric acid and sodium dodecyl sulfate.
The use of the dispersing agent enables all solid components and liquid components to be dispersed in the composite suspending agent more uniformly and rapidly, so that the prepared high-efficiency pesticide forms a uniform liquid phase.
Furthermore, the wetting agent is one of soybean lecithin and polyethylene glycol.
Among other things, the use of wetting agents enables the surface tension or interfacial tension of the respective solid raw material to be more easily wetted by the liquid phase in the composite suspending agent or other liquid raw material. The composite suspending agent or other liquid raw materials can be spread on the surface of the solid material or penetrate into the surface of the solid material, so that the solid material is fully wetted, and the dispersion of the raw materials is facilitated.
Furthermore, the emulsifier is selected from one of soybean phospholipid and lauric monoglyceride.
Wherein the emulsifier is used to improve the surface tension between various constituent phases in the high-efficiency pesticide, so that the high-efficiency pesticide forms a uniform and stable dispersion system or an emulsion. So that the prepared high-efficiency pesticide has more uniform and stable properties.

Experimental results and analysis:
a commercially available pesticide for red spider (comparative example) and the high-potency pesticide prepared by examples 1, 2, 3 and 4 of the present invention (examples) were formulated into a suspension having a concentration of 550g/L and diluted to 4000 times. Then, the red spiders on the citrus trees in the field are prevented, and 10 days after the pesticide is applied, the prevention effect data of the red spiders on the citrus trees are recorded as follows:
the test result shows that: compared with the commercially available red spider insecticide, the insecticide prepared by the invention has a better killing effect on red spiders in the field, is longer in pesticide effect duration and has a good market prospect.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
