The action mechanisms of the three components are different, under the synergistic effect, the seeds can have good insect pest and disease resistant effects, the emergence rate of the seeds and the disease and pest control effect can be obviously improved, the generation of drug resistance caused by long-term independent use is avoided, and the protection effect on the seeds is also improved.

Description

Technical Field

[0001] This invention relates to the field of pesticides, and more specifically to a seed treatment suspension containing cyproconazole, oxadixyl, and tebuconazole. Background Technology

[0002] Daofengsan is a non-systemic insecticide that works by binding to cholinesterase in animals to generate phosphorylated cholinesterase, thereby inhibiting the breakdown of acetylcholine by cholinesterase, leading to the interruption of nerve conduction and causing poisoning, thus achieving the effect of controlling pests.

[0003] Oxyphenidyl is a systemic fungicide and soil disinfectant. After entering the soil, oxyphenidyl is absorbed by the soil and combines with inorganic metal salt ions such as iron and aluminum in the soil, effectively inhibiting spore germination and the normal growth of pathogenic fungal mycelium or directly killing pathogens. Moreover, oxyphenidyl can be absorbed by plant roots and move within the root system. It is metabolized in the plant to produce two glycosides, which have the effect of improving the physiological activity of crops, thereby promoting plant growth, root tillering, increase of root hairs and increase of root activity.

[0004] Izoxystrobin is a triazole fungicide that is an inhibitor of ergosterol biosynthesis. It has systemic, protective, and therapeutic effects. Its mechanism of action is to inhibit the synthesis of ergosterol in pathogenic fungi at different sites of action, leading to cell membrane damage and death.

[0005] Seeds and seedlings are susceptible to damage and infection from various underground and above-ground pests and pathogens. When seeds and seedlings are eaten by pests or infected by pathogens, diseased seedlings or dead seedlings will occur, which will reduce the effective number of plants per unit area, resulting in large-scale crop yield reduction and quality decline.

[0006] Treating seeds with fungicides such as cyprodinil, oxadixyl, and tebuconazole can significantly reduce the damage caused by pests and pathogens. However, using these fungicides alone can easily lead to resistance, and large-scale use can pollute the environment. Moreover, the seed protection effect is still not ideal.

[0007] Theoretically, combining cyprodinil, oxamyl, and tebuconazole could solve the above problems. However, there are no reports in the existing technology on the preparation of seed treatment agents by combining cyprodinil, oxamyl, and tebuconazole. Summary of the Invention

[0008] To overcome the aforementioned technical problems, the present invention aims to provide a seed treatment suspension comprising cyproconazole, oxadixyl, and tebuconazole: by rationally compounding cyproconazole, oxadixyl, and tebuconazole, a seed treatment suspension is prepared, which is then used to coat seeds. This solves the problem that there are no reports in the prior art on the preparation of seed treatment agents by combining cyproconazole, oxadixyl, and tebuconazole, and the effect of the compounding of the three cannot be verified.

[0009] The objective of this invention can be achieved through the following technical solutions:

[0010] A seed treatment suspension comprising cymoxanil, oxadixyl, and tebuconazole, comprising the following components in the indicated weight ratios:

[0011] Active ingredients comprise 25-60%, with the remainder being other ingredients;

[0012] The active ingredients include isofensulfuron, oxamyl, and tebuconazole;

[0013] The mass ratio of the fungicides, oxadixyl and tebuconazole is 10-20:1-2:1-10.

[0014] As a further aspect of the present invention, the mass ratio of the rice-based fungicide, oxadixyl, and tebuconazole is 10:2:10.

[0015] As a further aspect of the present invention: the ingredients include wetting agent SP-2845W, dispersant SP-2836, separating powder, fumed silica, and deionized water.

[0016] As a further aspect of the present invention: the method for preparing the seed treatment suspension includes the following steps:

[0017] Step s1: Weigh out the active ingredient, wetting agent SP-2845W, dispersant SP-2836, separating powder, and fumed silica according to the mass ratio, and then add deionized water to make up to 100%.

[0018] Step s2: The active ingredients, wetting agent SP-2845W, dispersant SP-2836, separating powder, fumed silica and deionized water are sheared evenly, then ball-milled and sieved to obtain a seed treatment suspension containing cypermethrin, oxadixyl and tebuconazole.

[0019] As a further aspect of the present invention: the seed treatment suspension is used in the treatment of corn, rice, peanut, and wheat seeds.

[0020] The beneficial effects of this invention are:

[0021] This invention discloses a seed treatment suspension containing cypermethrin, oxadixyl, and tebuconazole. The seed treatment suspension is prepared by rationally compounding cypermethrin, oxadixyl, and tebuconazole. Seeds are then coated using this suspension. The cypermethrin in the suspension binds to cholinesterase in animals, generating phosphorylated cholinesterase, thereby inhibiting the breakdown of acetylcholine by cholinesterase, leading to nerve conduction interruption and poisoning, thus achieving the effect of pest control. The oxadixyl in the suspension inhibits spore germination and the normal growth of pathogenic fungal mycelium or directly kills pathogens. To achieve the effect of preventing and controlling pathogens, the tebuconazole in the seed treatment suspension can inhibit and suppress the synthesis of ergosterol in pathogenic fungi, leading to cell membrane damage and death, thereby achieving the effect of preventing and controlling pathogens. Therefore, after treating seeds with the seed treatment suspension, the three mechanisms of action of tebuconazole, hymexazol, and tebuconazole can be used to control pests and pathogens respectively. The three mechanisms of action are not the same, and their synergistic effect can make the seeds have good resistance to pests and diseases, significantly improve the seedling emergence rate and pest and disease control efficacy, not only avoiding the development of drug resistance caused by long-term use of individual drugs, but also improving the protection effect of seeds.

[0067] Blank example:

[0068] The blank example represents untreated corn seeds.

[0069] The corn seeds of Examples 1-8 and Comparative Examples 1-6 were treated using conventional seed coating methods. The mass ratio of active ingredient to corn seed was 1:50. After diluting the active ingredient with water, the corn seeds were coated and dried. The germination rate of each sample was investigated on the 7th day after sowing, and the disease and pest control efficacy of each sample was investigated on the 60th day. The test results are shown in the table below:

[0070]

[0071]

[0072] Referring to the data in the table above, and comparing Examples 1-8 with Comparative Examples 1-6 and the blank control, it can be seen that treating corn seeds with a seed treatment suspension of cypermethrin, oxadixyl, and tebuconazole can improve their germination rate and disease and pest resistance. Furthermore, when cypermethrin, oxadixyl, and tebuconazole are combined, their germination rate and disease and pest resistance can be further improved. In particular, the seed treatment suspension of cypermethrin, oxadixyl, and tebuconazole has the best effect. When the mass ratio of cypermethrin, oxadixyl, and tebuconazole is 10:2:10, the germination rate reaches 95.2%, the disease control efficacy reaches 96.6%, and the pest control efficacy reaches 97.8%.
