Problems solved by technology

[0003] Emodin methyl ether is the active ingredient extracted from Polygonaceae Polygonum cuspidatum and rhubarb. Because it comes from natural substances, it is a real pollution-free plant-derived biopesticide, but any pesticide must be made into a preparation before it can be used effectively, and rhubarb Phytomethyl ether is only soluble in organic solvents such as benzene, chloroform, and toluene, and hardly soluble in water, methanol, and ethanol. The above characteristics make emodin methyl ether and its rhubarb extract anthraquinone fungus-inhibiting products natural green and pollution-free plants Characterization of source pesticides is limited

Embodiment 1

[0034] Embodiment 1: the preparation of 0.5% emodin methyl ether suspension seed coating agent

[0035] (following materials all will reach dehydration constant weight) the mass percent of each component is as follows:

[0036] The original powder of emodin methyl ether is 5.9%. The original powder is a mixture of emodin methyl ether, chrysophanol, rhein and other extracts, wherein the mass content of emodin methyl ether is 8.5%. Sodium lignosulfonate (molecular weight 2000, the same below) 5%, sodium alginate 5%, glycerin 5%, xanthan gum 0.2%, sorbic acid 0.5%, organic fertilizer potassium fulvic acid 2%, organic silicon defoamer 0.4%, water 76.0%. The total amount is 1000 grams.

[0037] Make:

[0038] 1) Weigh 66% water, then add sodium lignosulfonate as a dispersant, add 5.9% emodin methyl ether mother drug after fully dissolving, then add film-forming agents sodium alginate, glycerin, sorbic acid, potassium fulvate, Defoamer, mix thoroughly and evenly.

[0039] 2) Sl...

Embodiment 2

[0040] Embodiment 2: the preparation of 0.8% emodin methyl ether suspension seed coating agent

[0041] The original powder of emodin methyl ether is 10%, and the original powder is a mixture of emodin methyl ether, chrysophanol, rhein and other extracts, wherein the mass content of emodin methyl ether is 8.5%. Sodium lignosulfonate 6%, glycerin 5%, xanthan gum 0.2%, sodium alginate 6%, sorbic acid 0.5%, potassium fulvic acid 2%, silicone defoamer 0.4%, water 69.9%. The total amount is 1000 grams.

[0042] 1) Weigh 59.9% water, then add 6% sodium lignosulfonate, add 11.8% parent drug of emodin methyl ether after fully dissolving, add 0.2% xanthan gum, then add 6% sodium alginate, 5% glycerin, 0.5% sorbic acid, 2% potassium fulvic acid, 0.4% defoamer, mix well.

[0043] 2) Slowly add 0.2% xanthan gum to the remaining 10% water while stirring to make xanthan gum mother liquor, and then add it to the above mixture, a total of 1000g, glass beads: feed solution = 0.6:1, and then us...

Embodiment 3

[0044] Embodiment 3: the preparation of 2% emodin methyl ether suspension seed coating agent

[0045] The original powder of emodin methyl ether is 23.6%. The original powder is a mixture of emodin methyl ether, chrysophanol, rhein and other extracts, wherein the mass content of emodin methyl ether is 8.5%. Sodium lignosulfonate 8%, sodium alginate 8%, glycerin 5%, xanthan gum 0.2%, sorbic acid 0.5%, potassium fulvic acid 2%, defoamer 0.4%, water 52.3%. 1000 grams in total.

[0046] Make:

[0047] 1) Weigh 52.3% water, then add 8% sodium lignosulfonate, add 23.6% parent drug of emodin methyl ether after fully dissolving, add 0.2% xanthan gum, then add 8% sodium alginate, 5% glycerin, 0.5% sorbic acid, 2% potassium fulvic acid, 0.4% defoamer, mix well.

[0048] 2) Glass beads: feed liquid = 0.6:1, then use a vertical sand mill to start grinding, and use a laser particle size analyzer to detect the particle size. When 95% of the grinding particles are less than 5 microns, you...

Abstract

The invention discloses a physcion suspension seed coating agent which includes, by mass, 0.1-7 parts of physcion, 0.2-3 parts of a thickener, 0.4-0.8 parts of a preservative, 2-10 parts of a film-forming agent, 5-22 parts of an auxiliary material, 5-10 parts of a dispersant, 3-6 parts of an anti-freeze agent, 2 parts of an organic fertilizer, 0.4 parts of a defoamer and 40-82 parts of water. The invention also discloses a preparation method and an application of the physcion suspension seed coating agent. The novel suspension seed coating agent can completely avoid large amount usage of organic solvents and is free of any environment pollution. The auxiliary materials are all natural plant-source and mineral products and edible substances. The suspension seed coating agent guarantees the characters that the physcion is high-efficiency and low-toxicity, can be naturally degraded, is safe to human and animals, and has no damages on enemies of pests. The organic suspension seed coating agent is provided for production of organic foods.

Description

technical field [0001] The invention belongs to the application field of emodin methyl ether, and in particular relates to a production process of a seed coating agent and a use method thereof. Background technique [0002] Seed coating agent is a new method of using pesticides that can be directly wrapped on seeds. It isolates seeds from pathogens through film-forming agents, and directly kills harmful organisms in seeds and soil, so as to achieve precise and convenient drug use. Purpose. At present, seed coating products are growing at a rate of more than 5% per year. The application field is expanding from wheat, rice, and corn to soybeans, peanuts, vegetables, melons, etc., and because it is suitable for mechanized operations, it is simple and efficient, labor-saving and time-saving The characteristics are being highly valued by the market. Pesticide suspension seed coating agents mostly use water as the dispersion medium, and the insoluble or slightly water-soluble so...
