Problems solved by technology

[0004] Since the research and development of seed coating agents in my country started relatively late, and the production technology and detection level were still relatively backward, after a large number of comparative experiments and observation studies, it was found that there are still some problems in the development and application of seed coating agents in my country: on the composition of active ingredients, The drug formula is single, the pertinence is poor, the formula is not reasonable, and the actual application effect is not ideal; the film forming technology is not mature enough, the shedding rate is high, and it is easy to cause phytotoxicity, etc.
For example, wheat seed coating agents, some are aimed at underground pests, and some are used to prevent and control wheat sheath blight. At present, there is no seed coating agent that can effectively prevent and control underground pests and sheath blight and can promote growth and increase production.

Embodiment 1

[0081] Example 1: 4g of Lesben, 0.3g of diniconazole, 0.1g of sodium nitrophenolate, 1g of sodium carboxymethylcellulose, 1g of formaldehyde condensate of naphthalenesulfonate, 2g of calcium dodecylbenzenesulfonate, benzene Sodium formate 1g, fumed white carbon black 0.1g, 5000 mesh kaolin 10g, basic rhodamine 1.5g, water 79g.

[0082] Preparation method: first heat water to 50°C, stir and add sodium carboxymethyl cellulose and rhodamine basic, completely dissolve and become a film-forming solvent, then add Lesperm, diniconazole, and compound to the film-forming solvent Sodium nitrophenolate, naphthalenesulfonate formaldehyde condensate, calcium dodecylbenzenesulfonate, sodium benzoate, fumed white carbon black and kaolin are sent into a stirring tank and stirred evenly to form a suspension seed coating agent.

Embodiment 2

[0083] Example 2: Lesibon 6g, diniconazole 0.4g, sodium nitrophenolate 0.3g, methylcellulose 1.2g, naphthalenesulfonate formaldehyde condensate 1.2g, calcium dodecylbenzenesulfonate 2.4g, Sodium benzoate 1.2g, fumed white carbon black 0.2g, 1500 mesh kaolin 7g, basic scarlet 1.2g, water 78.9g.

[0084] Preparation method: first heat the water to 60°C, stir and add methyl cellulose and basic scarlet, completely dissolve and become a film-forming solvent, then add Lesbon, diniconazole, and sodium nitrophenolate into the film-forming solvent , naphthalene sulfonate formaldehyde condensate, calcium dodecylbenzene sulfonate, sodium benzoate, fumed white carbon black and kaolin, and then put it into a stirring tank and stir evenly to form a suspension seed coating agent.

Embodiment 3

[0085] Example 3: Lesibon 7, diniconazole 0.5g, sodium nitrophenolate 0.5g, polyvinyl alcohol 1.5g, naphthalenesulfonate formaldehyde condensate 1.5g, calcium dodecylbenzenesulfonate 3g, sodium benzoate 1.5g, fumed silica 0.15g, talcum powder 5g, basic rhodamine 1g, water 78.35g.

[0086] Preparation method: firstly heat the water to 70°C, stir and add polyvinyl alcohol and rhodamine alkaline, after completely dissolving, it becomes a film-forming solvent, and then add Lesben, diniconazole, sodium nitrophenolate, Naphthalenesulfonate formaldehyde condensate, calcium dodecylbenzenesulfonate, sodium benzoate, fumed white carbon black and talcum powder are sent into a stirring tank and stirred evenly to form a suspension seed coating agent.

Abstract

The invention provides a high-efficiency, low-toxicity multifunctional suspension seed coating agent for wheat, which is composed of the following raw materials in mass percentage: 4-7% of Lesben, 0.3-0.5% of diniconazole, 0.1-0.5% of sodium nitrophenolate, Film-forming agent 1-1.5%, dispersant 1-1.5%, calcium dodecylbenzenesulfonate 2-3%, preservative 1-1.5%, thickener 0.1-0.2%, filler 5-10%, Warning pigment 1-1.5%, balance is water. The seed coating agent of the invention is mainly used for seed coating before sowing of wheat, can effectively prevent and control wheat sheath blight and underground pests, can also promote roots and seedlings, enhance stress resistance of crops, and increase wheat yield.

Description

technical field [0001] The invention relates to a seed coating agent, in particular to a high-efficiency, low-toxicity and multifunctional suspension seed coating agent for wheat, which can effectively prevent and control wheat sheath blight and underground pests, promote roots and seedlings, and enhance crop stress resistance ,Increase production. Background technique [0002] In agricultural research and production, seed pesticide treatment is one of the most economical and convenient methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. Seed coating technology is a new seed treatment technology widely used in the world developed on the basis of traditional seed soaking or seed dressing technology. The comprehensive supporting technology integrating pesticide, plant protection, chemical industry, machinery and other disciplines by means of machinery is an organic combination of modern seed processing, standardization of seed quality...
