Embodiment 1

[0084] Example 1: 4g of Lesben, 2g of diniconazole, 0.1g of sodium nitrophenolate, 1g of sodium carboxymethylcellulose, 1g of naphthalenesulfonate formaldehyde condensate, 2g of calcium dodecylbenzenesulfonate, and sodium benzoate 1g, antifreeze agent 4g, 5000 mesh kaolin 10g, basic rhodamine 1.5g, water 73.4g.

[0085] 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, antifreeze and kaolin are sent into a stirring tank and stirred evenly to form a compound corn seed coating agent.

Embodiment 2

[0086] Example 2: 5g of Lesben, 3g of diniconazole, 0.3g of sodium nitrophenolate, 1.2g of methylcellulose, 1.2g of naphthalenesulfonate formaldehyde condensate, 2.4g of calcium dodecylbenzenesulfonate, benzene Sodium formate 1.2g, antifreeze agent 2g, 1500 mesh kaolin 7g, basic scarlet 1.2g, water 75.5g.

[0087] 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 , naphthalenesulfonate formaldehyde condensate, calcium dodecylbenzenesulfonate, sodium benzoate, antifreeze and kaolin, and then put it into a stirring tank and stir evenly to form a compound corn seed coating agent.

Embodiment 3

[0088] Example 3: Lesibon 7, diniconazole 4g, sodium nitrophenolate 0.5g, polyvinyl alcohol 1.5g, naphthalenesulfonate formaldehyde condensate 1.5g, calcium dodecylbenzenesulfonate 3g, sodium benzoate 1.5g g, antifreeze 1g, talcum powder 5g, basic rhodamine 1g, water 74g.

[0089] 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, antifreeze agent and talcum powder are sent into a stirring tank and stirred evenly to form a compound corn seed coating agent.

Abstract

The invention provides a composite corn seed coating agent which comprises the following raw materials according to the mass percent: 4 percent to 7 percent of chlorpyrifos, 2 percent to 4 percent of dniconazole, 0.1 percent to 0.5 percent of compound sdium ntrophenolate, 1 percent to 1.5 percent of film-forming agent, 1 percent to 1.5 percent of dispersant, 2 percent to 3 percent of calcium dodecyl benzene sulfonate, 1 percent to 1.5 percent of preservative agent, 1 percent to 4 percent of antifreeze agent, 5 percent to 10 percent of bulking agent, 1 percent to 1.5 percent of alert color and the rest of water. The seed coating agent is mainly used for seed coating before the corn sowing, can effectively control the maize head smut and the soil insects, also can promote the breeding of roots and healthy seedlings, enhance the anti-adversity of the crops and improves the yield of the corns. The test result shows that the control effect of the seed coating agent to the maize head smut reaches 87.65 percent and 90.53 percent, and the control effect of the seed coating agent to the soil insects of the corns reaches 76.84 percent and 85.69 percent, and the yield increasing rate reaches 7.6-10.2 percent.

Description

technical field [0001] The invention relates to a seed coating agent, in particular to a composite corn seed coating agent. The seed coating agent can effectively prevent and control corn head smut and underground pests, promote roots and seedlings, enhance crop stress resistance, and increase yield. 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 and integrated pest control in the field.
