Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The embodiment of the present invention provides a pesticide synergistic formula for rice false smut and ear neck blast, comprising:

[0025] Disease pesticides, silicone adjuvants, water, active adjuvants and rice seedling protectants;

[0026] The disease-causing pesticide is a mixture of two pesticide preparations, the two pesticide preparations are azoxystrobin suspension and tricyclazole wettable powder, wherein the azoxystrobin suspension includes azoxystrobin technical, sodium lignin sulfonate, alkyl naphthalene sulfonate, xanthan gum, ethylene glycol and organosilicon defoamer, and the rest is water, and the tricyclazole technical includes lignin sulfonate and naphthalene sulfonate formaldehyde condensate, sodium lauryl sulfate and lakai powder, and diatomaceous earth;

[0027] Silicone additives include silicone surfactants, emulsifiers and solvents;

[0028] The active ingredients include azone, vegetable oil, carboxymethyl cellulose and antioxidants;

[0030] The mass percentages of the pest control pesticide, organosilicon adjuvant, water, active adjuvant and rice seedling protective agent are as follows: 20%-30% pest control pesticide: 0.5%-1% organosilicon adjuvant: 3%-8% active adjuvant: 1%-5% rice seedling protective agent, and the rest is water.

[0031] Specifically, disease pesticides are the main control ingredients that can inhibit and kill the pathogens that cause rice false smut and panicle blast, thereby protecting rice from diseases and reducing yield losses;

[0032] Silicone additives enhance the spread and penetration of the liquid on rice leaves and plants, allowing the pesticide to more evenly cover and enter plant tissues, improving the prevention and control effect;

[0033] Active additives may include penetrants to help the pesticide solution penetrate better into the plant, synergists to enhance the activity and efficacy of the pesticide, adhesives to improve the adhesion of the pesticide solution to the plant surface, and stabilizers to ensure the stability of the pesticide during storage and use;

[0034] Rice seedling protectant reduces the possible damage of disease pesticides to rice seedlings, promotes the growth and development of rice seedlings, enhances the resistance of rice seedlings, and ensures the healthy growth of rice seedlings;

[0035] Water acts as a solvent and carrier to evenly mix the other ingredients to form a liquid medicine that is easy to apply.

[0036] The active ingredients of the two pesticide preparations in the disease-killing pesticide are azoxystrobin suspension, whose weight accounts for 15-25% of the total weight of the active ingredients, and tricyclazole wettable powder, whose weight accounts for 75-85% of the total weight of the active ingredients. The total weight of the active ingredients is the sum of the weights of the azoxystrobin suspension and the tricyclazole wettable powder.

[0037] Specifically, azoxystrobin suspension has a broad-spectrum fungicidal activity, can inhibit the energy production of pathogens, interfere with their normal physiological processes, and effectively prevent and treat a variety of fungal diseases;

[0038] Tricyclazole wettable powder mainly prevents the rice blast fungus from invading rice plants by inhibiting the germination of its spores and the formation of attached spores. It is very effective in preventing rice blast and panicle blast.

[0039] The material ratios of the azoxystrobin suspension are as follows: the mass percentage of azoxystrobin original drug is 25-35%, the mass percentage of sodium lignin sulfonate is 3-6%, the mass percentage of alkyl naphthalene sulfonate is 2-4%, the mass percentage of xanthan gum is 0.15-0.3%, the mass percentage of ethylene glycol is 5-10%, the mass percentage of silicone defoamer is 0.2-0.4%, and the rest is water.

[0040] Specifically, azoxystrobin technical is an active ingredient that exerts a bactericidal effect and can inhibit the growth and reproduction of pathogenic bacteria, thereby achieving the purpose of preventing and controlling diseases;

[0041] Sodium lignin sulfonate, as a dispersant, makes the azoxystrobin technical particles evenly dispersed in the suspending agent, prevents the particles from agglomerating and settling, and ensures that the concentration of the agent is uniform when used;

[0042] Alkylnaphthalene sulfonate, as a wetting agent, helps the suspension agent to quickly wet and spread on the crop surface, increase the contact area between the agent and the crop surface, and enhance the efficacy;

[0043] Xanthan gum is a thickener that increases the viscosity of the suspension, prevents solid particles from settling, and maintains the stability and uniformity of the suspension;

[0044] Ethylene glycol, as an antifreeze, lowers the freezing point of water, preventing the suspension from freezing in low-temperature environments, ensuring normal use under different temperature conditions;

[0045] Silicone defoamers are used to eliminate foam generated during production and use to ensure the quality and effectiveness of the preparation. Water is used as the main solvent and carrier to dissolve or disperse other ingredients to form a stable suspension system.

[0046] The material ratios of the tricyclazole technical are as follows: the mass percentage of lignin sulfonate and naphthalene sulfonate formaldehyde condensate is 3%-8%, the mass percentage of sodium lauryl sulfate and lautering powder is 1%-3%, and the mass percentage of diatomaceous earth is 15%-20%.

[0047] Specifically, lignin sulfonate and naphthalene sulfonate formaldehyde condensate, as dispersants, can make tricyclazole technical particles evenly dispersed in the preparation, prevent particle agglomeration and precipitation, and ensure uniform concentration of the preparation when it is used;

[0048] Sodium laurel sulfate and lautering powder, these two substances act as wetting agents, which can improve the wetting performance of the preparation on the surface of crops, allowing the liquid medicine to cover the crops more quickly and evenly, thus improving the efficacy of the medicine;

[0049] Diatomaceous earth is used as a carrier to carry and adsorb tricyclazole technical and other auxiliary agents to ensure the physical stability of the preparation and facilitate storage and transportation.

[0050] The ratio of each material in the organosilicon additive is 60%-80% by mass of the organosilicon surfactant, 10%-20% by mass of the emulsifier and 10%-20% by mass of the solvent.

[0051] Specifically, organosilicon surfactants, which are the main active ingredients of organosilicon adjuvants, can significantly reduce the surface tension of the liquid medicine, enhance the expansibility and permeability of the liquid medicine on the crop surface, and increase the coverage area and absorption efficiency of the liquid medicine;

[0052] Emulsifiers help to evenly disperse the silicone surfactant in the solvent to form a stable emulsion system, and also promote the uniform mixing of silicone adjuvants and other pesticide ingredients;

[0053] Solvents act as carriers to dissolve and dilute silicone surfactants and emulsifiers so that they can be used in pesticide formulations in appropriate concentrations and forms.

[0054] The proportions of various materials in the active auxiliary agent are as follows: the mass percentage of azone is 20-30%, the mass percentage of vegetable oil is 30-40%, the mass percentage of carboxymethyl cellulose is 20-30% and the mass percentage of antioxidant is 5-15%.

[0055] Specifically, azone, as a penetrant, can promote the penetration of the active ingredients of pesticides through the plant epidermis, increase their penetration depth and speed in the plant body, and improve the efficacy;

[0056] As a synergist, vegetable oil can enhance the activity and adhesion of pesticides, prolong the residence time of pesticides on the plant surface, and thus improve the control effect;

[0057] Carboxymethyl cellulose acts as an adhesive to increase the adhesion of the drug solution on the plant surface, preventing the drug solution from being lost due to factors such as rain erosion, thus ensuring the long-term efficacy of the drug.

[0058] Antioxidants act as stabilizers to prevent active additives from deteriorating due to oxidation during storage and use, ensuring their performance is stable and lasting;

[0059] The proportions of various materials in the rice seedling protective agent are as follows: the mass percentage of brassinolide is 30%-40%, the mass percentage of aminoethyl hexanoate is 20%-30%, the mass percentage of proline is 20%-30% and the mass percentage of amino acid is 10%-20%.

[0060] Specifically, brassinolide is an important plant growth regulator that can effectively regulate the growth and development process of rice seedlings. It can enhance the physiological activity of rice seedling cells, stimulate cell division and elongation, and thus promote the healthy growth of rice seedlings. In addition, brassinolide can also significantly improve the stress resistance of rice seedlings. Whether facing the invasion of cold, the threat of drought, or other harsh environmental conditions, it can help rice seedlings maintain a stable growth state and reduce the adverse effects of external adverse factors on the growth of rice seedlings.

[0061] Aminoethyl hexanoate can significantly improve the photosynthetic efficiency of rice seedlings, increase the synthesis and accumulation of chlorophyll, and thus provide more sufficient energy and material basis for the growth of rice seedlings. By promoting the nutritional growth of rice seedlings, the stems are stronger and the leaves are more luxuriant. At the same time, aminoethyl hexanoate can also enhance the adaptability of rice seedlings to the complex and changing external environment, helping rice seedlings maintain a good growth trend when facing pressure.

[0062] Proline plays a key role in plants' response to stress. When rice seedlings encounter adverse environmental conditions, such as high temperature, drought or salinity, proline can quickly accumulate in the cells to help maintain the osmotic pressure balance of the cells and prevent the cells from being damaged by excessive water loss. It acts as a protective guard for the cells, reducing the damage caused by adversity to the rice seedlings and ensuring the normal physiological functions of the rice seedlings.

[0063] Amino acids, as direct nutrients required for the growth of rice seedlings, provide indispensable nutrient support for the growth and development of rice seedlings. They can participate in various metabolic processes in the rice seedlings, promote protein synthesis, and enhance enzyme activity, thereby improving the growth vitality and immunity of rice seedlings and ensuring that rice seedlings grow healthily under good nutritional conditions.
