Description

Technical Field

[0001] The present application relates to the field of seed pesticides, and in particular to a seed treatment suspension concentrate, a preparation method thereof, and an application thereof. Background Art

[0002] Seed treatment suspension concentrates are used to treat seeds during processing or just before sowing, using methods such as coating, dressing, soaking, or suffocating. The agent and treatment method are typically selected based on the crop type and the local pest risk (diseases, insects, rodents, etc.).

[0003] Seeds, a vital agricultural resource, are vulnerable to over 700 pests and diseases due to their tenderness and low resistance. Existing seed treatment suspension concentrates offer limited disease resistance. Therefore, after sowing seeds treated with seed treatment suspension concentrates, pesticides must be sprayed shortly to prevent pests and diseases. This increases production costs and the accumulation of residual chemical pesticides in the soil. Summary of the Invention

[0004] In order to solve the problem of reducing the sowing of seeds treated with seed treatment suspension, and still needing to spray pesticides to prevent pests and diseases in the short term, the present application provides a seed treatment suspension, which improves the prevention and control effect of pests and diseases, thereby reducing the number of times pesticides are sprayed in the short term.

[0005] In the first aspect, the present application provides a seed treatment suspension concentrate, which adopts the following technical solution: A seed treatment suspension comprises a suspension composition and a solvent. The suspension composition comprises the following components in parts by weight: 20 parts of chlorantraniliprole, 5-10 parts of isomeric alcohol ether phosphate, 2-6 parts of alkaloids, and 2-6 parts of terpene compounds.

[0006] By employing this technical solution, alkaloids can interact with the nervous system receptors of certain insects, affecting the conduction and release of nerve impulses, thereby achieving an insecticidal effect. When used in combination with chlorantraniliprole, synergistic effects may be achieved by increasing neurotoxicity, reducing insect resistance, or interfering with their metabolic processes. This synergistic effect helps seeds maintain resistance for a longer period after treatment, resisting attacks by various pests and pathogens. Furthermore, alkaloids have a low alkalinity, and their insecticidal effect primarily stems from their inherent structure. Small amounts of alkaloids and chlorantraniliprole can have a synergistic effect.

[0007] Terpene compounds have natural antibacterial activity and can destroy the cell membrane structure of pathogens or interfere with their metabolic processes. They may achieve synergistic effects by increasing cell membrane permeability, inhibiting the enzyme activity of pathogens or interfering with their metabolic pathways.

[0008] The addition of isomeric alcohol ether phosphates not only enhances insecticidal and fungicidal effects but also significantly improves the stability of the entire suspension concentrate. This means the suspension concentrate can maintain the stability and activity of its active ingredients for a longer period of time, ensuring continued seed protection during storage and planting. Isomeric alcohol ether phosphates primarily form complexes with other ingredients, which are more stable at low temperatures and less prone to crystallization or precipitation. At high temperatures, some molecules of the isomeric alcohol ether phosphates may interact with other ingredients, stabilizing their molecular structure and preventing thermal decomposition.

[0009] The present application enhances the control effect of the seed treatment suspension on pests and diseases by synergizing isomeric alcohol ether phosphates, alkaloids, terpene compounds and chlorfenapyr, and also enhances the stability of the seed treatment suspension, thereby reducing the number of pesticide spraying times in the short term after sowing seeds treated with the seed treatment suspension.

[0010] Preferably, the alkaloid comprises at least one of nuciferine, matrine and oxymatrine.

[0011] By employing the above-mentioned technical solution, both matrine and oxymatrine exhibited moderate insecticidal activity, potentially through interference with the insect nervous system. Combining them with chlorantraniliprole further enhanced their insecticidal efficacy. Both nuciferine and oxymatrine possess antibacterial and anti-inflammatory properties. The addition of these alkaloids may also help improve the stability of seed treatment suspension concentrates, maintaining the stability and activity of the active ingredients during storage and use.

[0012] Preferably, the mass ratio of chlorantraniliprole to nuciferine is 20:4-6.

[0013] By adopting the above technical solution, nuciferine and chlorantraniliprole can achieve optimal synergistic effects at a specific mass ratio. When the content of nuciferine is too high, the balance of this synergistic effect may be disrupted, resulting in an overall effect that is less than expected. If the content of nuciferine is too low, this synergistic effect will not be fully exerted, resulting in a weakened overall effect. Nuciferine not only plays a synergistic insecticide role in the preparation, but also has certain antibacterial and anti-inflammatory functions. If the content is too low, these functional requirements will not be met.

[0014] Preferably, the terpene compound includes at least one of borneol and camphor.

[0015] By adopting the above technical solution, borneol has certain antibacterial and anti-inflammatory effects, which can enhance the bactericidal function of seed treatment suspension concentrates to a certain extent. Borneol can increase the permeability of other active ingredients in the suspension concentrate on the seed surface, thereby improving the efficacy of the drugs. Borneol also has a certain stabilizer effect, which can help improve the overall stability of the suspension concentrate.

[0016] Camphor has a natural insect repellent effect, which can further enhance the protective function of seed treatment suspensions. Camphor also exhibits some fungicidal properties, which can provide a better sterilization effect.

[0017] Preferably, the seed treatment suspension further comprises 3-5 parts of a fluorescent agent.

[0018] By adopting this technical solution, seed-feeding pests (such as white grubs) are mostly nocturnal. By adding a fluorescent agent to the seed treatment suspension, the fluorescent agent remains on the surface and body of the treated seeds after the insects have eaten them, enhancing their visibility and identification. The luminescent pests naturally attract their predators, such as predatory insects and birds, increasing their chances of being preyed upon. For example, white grubs have a white skin that allows for greater light transmission. Therefore, when the fluorescent agent is ingested by them, the fluorescence is more pronounced, making them more easily detected by their natural enemies (such as birds and insects). Chlorantraniliprole, as an insecticide, weakens the pests and reduces their mobility. This reduced mobility further increases the chances of capture by natural enemies.

[0019] Furthermore, chlorantraniliprole interferes with the pest's physiological functions, including its ability to degrade the fluorescent agent. Consequently, the insect's ability to decompose the fluorescent agent is significantly reduced, allowing the agent to continue luminescing within the insect's body. Even if the insect is able to partially decompose the fluorescent agent, the decomposition process may produce toxic byproducts. These byproducts are directly toxic to the pest and can further accelerate its death.

[0020] Preferably, the seed treatment suspension further comprises 5-10 parts of a fluorescent agent.

[0021] By employing the above-mentioned technical solution, honey, as a natural sugar, has a strong attraction to many pests. Adding honey to seed treatment suspension concentrates significantly increases pests' appetite for the concentrate, thereby increasing their chances of ingesting active ingredients like chlorantraniliprole and fluorescent agents. Honey's unique aroma further attracts pests to the seeds containing the suspension concentrate, leading to their ingestion. This dual attraction mechanism makes it even more difficult for pests to resist the suspension concentrate.

[0022] Honey's brown surface and stickiness effectively coat the fluorescent agent particles, forming a protective film. This film reduces the effects of external factors, such as light and oxygen, during preparation and storage, thereby delaying premature luminescence and improving its stability. When pests ingest a suspension containing honey and fluorescent agent, the honey is first decomposed and absorbed by the insects. As the honey is gradually consumed, the encapsulated fluorescent agent is released. This delayed release mechanism ensures that the fluorescent agent does not begin to emit until it reaches a high concentration within the pest's body, thereby enhancing its pest identification effectiveness.

[0023] When the fluorescent agent is released and glows inside the insect's body, the insect has already ingested a large amount of the active ingredient of the suspension concentrate (such as chlorantraniliprole), which severely affects its physiological functions. The fluorescence emitted at this time is more prominent, making it easier for natural enemies to detect it, thereby increasing the probability of predation.

[0024] In a second aspect, the present application provides a method for preparing a seed treatment suspension concentrate, which adopts the following technical solution: A method for preparing a seed treatment suspension concentrate is used to prepare the seed treatment suspension concentrate, comprising the following steps: mixing a formulated amount of chlorantraniliprole, isomeric alcohol ether phosphate, alkaloids, and terpene compounds, grinding the mixture to form a mixture, adding the mixture to a solvent, and mixing to obtain the seed treatment suspension concentrate.

[0025] By adopting the above technical solution, the raw materials in the above formula amounts are mixed and thoroughly mixed and refined through a grinding process to ensure the uniformity of the raw materials and the stability of the suspension. The ground raw material mixture is added to a solvent. The choice of solvent should take into account its solubility, safety, and compatibility with the raw materials. Commonly used solvents can be water or other environmentally friendly solvents. The raw material mixture is thoroughly mixed in the solvent, and stirring or other homogenization methods are used to ensure the uniform distribution of the various components in the suspension.

[0026] Preferably, a formulated amount of fluorescent agent is added to the mixture to form a fluorescent mixture, which is then added to a solvent and mixed to obtain a seed treatment suspension.

[0027] Preferably, the honey and the fluorescent agent in a formulated amount are mixed and added to the mixture to form an attractant fluorescent mixture, which is then added to a solvent and mixed to obtain a seed treatment suspension.

[0028] By adopting the above technical solution, after the fluorescent agent and honey are mixed, the honey can better wrap the fluorescent agent, effectively preventing the fluorescent agent from being excited in large quantities before entering the body of the pest.

[0029] In a third aspect, the present application provides an application of a seed treatment suspension concentrate, which adopts the following technical solution: This seed treatment suspension has excellent insecticidal and fungicidal effects, and has good stability. It can be well coated on the surface of seeds and can be used for the control of underground pests of peanuts, wheat, corn, soybeans, cotton, rice, and potato crops, as well as the control of seed-borne or soil-borne diseases and pests.

[0030] In summary, this application has the following beneficial effects: 1. Because the present invention utilizes isomeric alcohol ether phosphates, alkaloids, terpene compounds, and chlorantraniliprole to synergize with each other, the seed treatment suspension concentrate has enhanced pest and disease control effects and also enhanced stability. Thus, after sowing seeds treated with the seed treatment suspension concentrate, the number of pesticide sprayings can be reduced in the short term. 2. This invention adds a fluorescent agent to the insects to make them more easily identified after biting, making them more likely to be preyed upon by natural enemies. Even if the insects degrade the fluorescent agent, toxic and harmful byproducts will be produced, causing harm to the insects themselves. 3. The present application adds honey, which can not only increase the attractiveness of the seed treatment suspension to pests, but also wrap the fluorescent agent, reducing the risk of the fluorescent agent being stimulated in large quantities before being swallowed by pests.

The test results are shown in Table 1: 1. Seedling emergence rate and survival rate after 30 days Pour peanut seeds into the seed treatment suspension and stir thoroughly to form a uniform film on the surface of the seeds. Place in a cool place to dry before sowing in the test field, planting one seed per hole. Peanut grubs and root rot have occurred in the test field in previous years. No other insecticides or fungicides were used during the trial, and manual weeding was performed throughout. After 10 days, a "five-point method" was used to survey 120 holes in the test field, recording the emergence of peanut seedlings. This was repeated three times, and the average emergence rate of peanut seedlings was calculated. After 30 days, a "five-point method" was used to survey 120 holes in the test field, recording the survival of peanut plants. This was repeated three times, and the average survival rate of peanut plants was calculated.

[0037] 2. Low temperature stability According to GB / T19137-2003, the content of bottom segregant is determined; the lower the content, the better.

[0038] 3. Thermal storage stability The decomposition rate of chlorantraniliprole was determined according to GB / T19136-2003; the lower the decomposition rate, the better. The content of chlorantraniliprole was determined by high performance liquid chromatography. The chromatographic conditions for chlorantraniliprole were as follows: column: Agilent Eclipse XDB-C18 (4.6 mm × 250 mm, 5 μm); mobile phase: methanol-acetonitrile-water (10:10:80); detection wavelength: 270 nm; flow rate: 1.0 mL / min; column temperature: 25°C; injection volume: 20 μL.

[0039] Referring to Table 1, it can be seen from the comparison of Examples 1-3 and Comparative Examples 1-5 that, compared with Comparative Examples 1-5, the emergence rate and survival rate of Examples 1-3 are higher than those of Comparative Examples 1-5, and the bottom precipitate and decomposition rate are lower than those of Comparative Examples 1-5, indicating that the seed treatment suspension concentrate of Examples 1-3 has better control effect on pests and diseases and better stability; the results of Comparative Examples 1-4 show that isomeric alcohol ether phosphate, nuciferine, and borneol jointly improve the control effect and stability of the seed treatment suspension concentrate on pests and diseases; the results of Comparative Example 5 show that, compared with Tween 80, isomeric alcohol ether phosphate can further improve the control effect and stability of the seed treatment suspension concentrate on pests and diseases; In addition, by comparing Examples 1-3, it can be seen that the seed treatment suspension concentrate of Example 1 has the best performance.

[0040] Examples 4-7 In Examples 4-7, based on the preparation method of Example 1, the addition amount of isomeric alcohol ether phosphate was adjusted, and the specific adjustments are shown in Table 2.

[0041] The seed treatment suspending agents of Examples 4-7 were subjected to the above performance tests, and the test results are shown in Table 2.

[0042] Table 2 Addition amount and performance test table of isomeric alcohol ether phosphate of embodiment 1 and embodiment 4-7 project Example 1 Example 4 Example 5 Example 6 Example 7 Isomeric alcohol ether phosphate / kg 8 5 7 9 10 Seedling rate / % 95.3 91.9 94.5 94.1 91.6 Survival rate / % 86.2 84.3 85.8 85.7 84.6 Bottom separation / mL 0.03 0.20 0.07 0.08 0.19 Decomposition rate / % 2.08 3.81 2.49 2.66 3.88 Referring to Table 2, it can be seen from Example 1 and Examples 4-7 that as the amount of isomeric alcohol ether phosphate added continues to increase, the emergence rate and survival rate show a trend of first increasing and then decreasing, and the bottom segregant and decomposition rate show a trend of first decreasing and then increasing. This may be because as the amount of isomeric alcohol ether phosphate added continues to increase, the isomeric alcohol ether phosphate gradually combines and reacts with chlorfenapyr and other ingredients, continuously improving the control effect and stability of the seed treatment suspension on pests and diseases, thereby ensuring the effective ingredients in the seed treatment suspension, thereby enhancing the control effect of the seed treatment suspension on pests and diseases; when exceeding a certain range, part of the isomeric alcohol ether phosphate may exist alone as an unnecessary component, thereby affecting the control effect and stability of the seed treatment suspension on pests and diseases, and excessive isomeric alcohol ether phosphate also increases production costs.

[0043] Examples 8-11 In Examples 8-11, based on the preparation method of Example 1, the amount of nuciferine added was adjusted. The specific adjustments are shown in Table 3.

[0044] The seed treatment suspending agents of Examples 8-11 were subjected to the above performance tests, and the test results are shown in Table 3.

This may be because as the amount of nuciferine added continues to increase, the synergistic effect of nuciferine and chlorfenapyr continues to increase, thereby increasing the control effect and stability of the seed treatment suspension on pests and diseases; when it exceeds a certain range, the balance of this synergistic effect may be broken, resulting in the overall effect being less than expected, thereby affecting the control effect and stability of the seed treatment suspension on pests and diseases.

[0046] Examples 12-13 In Examples 12-13, based on the preparation method of Example 1, the amount of borneol added was adjusted, and the specific adjustments are shown in Table 4.

[0047] Comparative Examples 6-7 Comparative Examples 6-7 were based on the preparation method of Example 1, except that the amount of borneol added was adjusted. The specific adjustments are shown in Table 4.

[0048] The seed treatment suspending agents of Examples 12-13 and Comparative Examples 6-7 were subjected to the above performance tests. The test results are shown in Table 4.

[0049] Table 4: Amount of borneol added and performance test table of Example 1, Examples 12-13 and Comparative Examples 6-7 project Example 1 Example 12 Example 13 Comparative Example 6 Comparative Example 7 Borneol / g 4 2 3 5 6 Seedling rate / % 95.3 90.8 92.2 94.1 92.8 Survival rate / % 86.2 83.7 84.5 85.5 84.8 Bottom separation / mL 0.03 0.25 0.18 0.09 0.15 Decomposition rate / % 2.08 4.37 3.65 2.69 3.35 Referring to Table 4, it can be seen from Comparative Example 1, Examples 12-13 and Comparative Examples 6-7 that as the amount of borneol is increased, the emergence rate and the survival rate show a trend of first increasing and then decreasing, and the bottom precipitate and the decomposition rate show a trend of first decreasing and then increasing. This may be due to the increasing amount of borneol added, the compatibility between chlorantraniliprole, isomeric alcohol ether phosphate and borneol gradually changes from stable to unstable, so that the control effect and stability of the seed treatment suspension on pests and diseases gradually increase and then gradually decrease.

[0050] Examples 14-15 Examples 14-15 are based on the preparation method of Example 1, except that nuciferine is replaced with other types of alkaloids. The specific adjustments are shown in Table 5. Other conditions remain unchanged.

[0051] The seed treatment suspending agent of Examples 14-15 was subjected to the above performance test, and the test results are shown in Table 5.

[0053] Examples 16-19 In Examples 16-19, based on the preparation method of Example 14, the amount of oxymatrine added was adjusted. The specific adjustments are shown in Table 6.

[0054] The seed treatment suspending agents of Examples 16-19 were subjected to the above performance tests. The test results are shown in Table 6.

[0055] Table 6 Addition amount and performance test table of Example 14 and Examples 16-19 project Example 14 Example 16 Example 17 Example 18 Example 19 Oxymatrine / g 5 2 3 4 6 Seedling rate / % 91.4 92.6 94.8 93.7 90.4 Survival rate / % 84.1 84.7 85.9 85.3 84.1 Bottom separation / mL 0.22 0.16 0.05 0.11 0.24 Decomposition rate / % 4.06 3.45 2.33 2.89 4.46 Referring to Table 6, it can be seen from the comparison between Example 14 and Examples 16-19 that as the amount of oxymatrine added continues to increase, the emergence rate and survival rate show a trend of first increasing and then decreasing, while the bottom separation and decomposition rate show a trend of first decreasing and then increasing. This may be because as the amount of oxymatrine added continues to increase, the synergistic effect of oxymatrine and chlorfenapyr continues to increase, thereby increasing the control effect and stability of the seed treatment suspension on pests and diseases. When exceeding a certain range, the balance of this synergistic effect may be broken, resulting in an overall effect that is less than expected, thereby affecting the control effect and stability of the seed treatment suspension on pests and diseases. In addition, the ranges of oxymatrine and nuciferine are different, which may be caused by different molecular structures and alkalinity.

[0056] Example 20 Example 20 Based on the preparation method of Example 1, borneol is replaced by camphor, and other conditions remain unchanged.

[0057] The seed treatment suspending agent of Example 20 was subjected to the above performance test. The test results are shown in Table 7.

[0058] Table 7 Alkaloid types and performance test table of Example 1 and Example 20 project Example 1 Example 20 Alkaloid type borneol Camphor Seedling rate / % 95.3 95 Survival rate / % 86.2 86.0 Bottom separation / mL 0.03 0.04 Decomposition rate / % 2.08 2.23 Referring to Table 7, it can be seen from the comparison between Example 1 and Example 20 that both terpene compounds can be used in the present application. In addition, the seed treatment suspension concentrates containing two different terpene compounds have substantially equivalent performance.

[0059] Examples 21-22 In Examples 21-22, based on the preparation method of Example 1, the concentration of the suspension composition was adjusted. The specific adjustments are shown in Table 8.

[0060] Comparative Examples 8-9 Comparative Examples 8-9 were prepared according to the method of Example 1, except that the concentration of the suspension composition was adjusted. The specific adjustments are shown in Table 8.

[0061] The seed treatment suspending agents of Examples 21-22 and Comparative Examples 8-9 were subjected to the above performance tests. The test results are shown in Table 8.

[0062] Table 8 Concentration and performance test table of the suspension composition of Example 1, Examples 21-22 and Comparative Examples 8-9 project Example 1 Example 21 Example 22 Comparative Example 8 Comparative Example 9 Composition concentration / wt% 10 5 15 4 20 Seedling rate / % 95.3 91.1 94.3 89.8 91.2 Survival rate / % 86.2 83.9 85.8 82.5 84.2 Bottom separation / mL 0.03 0.24 0.17 0.32 0.34 Decomposition rate / % 2.08 4.21 3.57 4.99 5.11 Referring to Table 8, by comparing Example 1, Examples 21-22, and Comparative Examples 8-9, it can be seen that as the concentration of the suspension concentrate composition increases, the emergence rate and the survival rate first increase and then decrease, while the bottom separations and the decomposition rate first decrease and then increase. This may be because as the concentration of the suspension concentrate composition increases, the active ingredients in the suspension concentrate composition increase, which allows the seed treatment suspension concentrate to continuously exert its effective bactericidal and insecticidal effects. When the concentration exceeds a certain range, it affects the overall stability of the seed treatment suspension concentrate.

[0063] Examples 23-27 Example 23 Based on the preparation method of Example 1, 3 g of fluorescent agent was added to the suspension composition, and then added to 720 g of water to ensure that the concentration of the suspension composition was 10 wt %, and mixed to obtain a seed treatment suspension.

[0064] Example 24 Based on the preparation method of Example 1, 5 g of fluorescent agent was added to the suspension composition, and then added to 738 g of water to ensure that the concentration of the suspension composition was 10 wt %, and mixed to obtain a seed treatment suspension.

[0065] Example 25 Based on the preparation method of Example 1, 5g of fluorescent agent and 5g of honey are first mixed, then added to the suspension composition, and then added to 783g of water to ensure that the concentration of the suspension composition is 10wt%, and mixed to obtain a seed treatment suspension.

[0066] Example 26 Based on the preparation method of Example 1, 5g of fluorescent agent and 10g of honey are first mixed, then added to the suspension composition, and then added to 828g of water to ensure that the concentration of the suspension composition is 10wt%, and mixed to obtain a seed treatment suspension.

[0067] Example 27 Based on the preparation method of Example 1, 10 g of honey was added to the suspension concentrate composition, and then added to 783 g of water to ensure that the concentration of the suspension concentrate composition was 10 wt %, and mixed to obtain a seed treatment suspension concentrate.

[0068] The seed treatment suspending agents of Examples 23-27 were subjected to the above performance tests. The test results are shown in Table 9.

[0069] Table 9: Addition amount and performance test table of fluorescent agent and honey in Example 1 and Examples 23-27 project Example 1 Example 23 Example 24 Example 25 Example 26 Example 27 Fluorescent agent / g / 3 5 5 5 / Honey / g / / / 5 10 10 Seedling rate / % 95.3 95.5 96.1 96.3 96.5 95.6 Survival rate / % 86.2 88.7 90.2 91.6 93.4 88.1 Referring to Table 9, by comparing Example 1 with Examples 23-27, it can be seen that when the fluorescent agent is added to the seed treatment suspension, the survival rate of the peanut seedlings after 30 days is significantly improved, indicating that the fluorescent agent can effectively improve the insect control effect of the peanut seedlings. This may be because the fluorescent agent can increase the probability of being preyed upon by pests (such as white grubs), thereby effectively reducing the population size of the white grubs and protecting the growth of the peanut seedlings.

[0070] When fluorescent agent and honey were added simultaneously to the seed treatment suspension concentrate, the survival rate of peanut seedlings after 30 days was further improved, and the survival rate after 30 days was even higher than that of the seed suspension concentrate containing honey alone. This suggests that the combination of honey and fluorescent agent can further enhance the pest control effect of peanut seedlings. This is likely because honey not only attracts pests but also effectively prevents the fluorescent agent from emitting light prematurely, helping it accumulate in the pests' bodies, thereby further reducing the population of white grubs and protecting the growth of peanut seedlings.

[0071] Application Examples As shown in Examples 1-27, all of which were applied to peanuts, the seed treatment suspension concentrate of this application fully demonstrates its pest control efficacy and stability. Furthermore, the seed treatment suspension concentrate of this application can also be used to control underground pests and seed-borne or soil-borne pests in crops such as wheat, corn, soybeans, cotton, rice, and potatoes.
