Problems solved by technology

[0007] Extensive research has been carried out on the application technology and preparation processing technology of Sophora flavescens extract at home and abroad. Its use dosage is extremely low (only 0.15g of active ingredient matrine is needed per mu), and it is generally processed into a dosage form with a content of 0.1-3%. , all enter the environment during use, causing serious pollution; and processed into 0.1% soluble powder due to its strong hygroscopicity, there will be dust flying during packaging and use. These dosage forms can only be used for spraying, and the utilization rate is extremely low. thereby affecting the efficacy of the drug

Embodiment 1

[0045] Example 1: 0.3% Matrine-Brassinolide Suspension Seed Coating

[0046] 0.29 g of matrine, 0.01 g of brassinolide, 5 g of alkylphenol polyoxyethylene ether, 4 g of ethylene glycol, 0.15 g of xanthan gum, 1.0 g of white carbon black, 0.5 g of defoamer, and 0.1 g of mold agent, 3.0 g of everlasting red, 3 g of film-forming agent, 10 g of kaolin, 0.1 g of sorbic acid, and make up to 100 g of water. After stirring and mixing all the materials, grind them in a sand mill for 2 hours (rotating speed 2000-5000 / min) to obtain a magenta flowable suspension liquid, which is the finished product.

Embodiment 2

[0047] Example 2: 2.51% Matrine-Brassinolide Suspension Seed Coating

[0048] 25 kg of matrine, 0.1 kg of brassinolide, 20 kg of alkylnaphthalene sulfonate formaldehyde condensate sodium salt; 30 kg of alkylphenol polyoxyethylene ether, 40 kg of glycerin, and 10 kg of magnesium aluminum silicate , 5 kg of defoaming agent, 5 kg of antifungal agent, 10 kg of bentonite, 0.2 kg of citric acid, 2 kg of acid orange, and 850 kg of water.

[0049] All raw materials are put into a 1000L high-shear emulsification and dispersion kettle, fully emulsified and dispersed under airtight conditions, so that the slurry is more uniform and refined. Then transport the slurry to a sand mill for grinding, and the grinding material enters a blending kettle, then add 150 kg of 10% polyvinyl alcohol aqueous solution, stir and mix for 30 minutes, and then discharge. The obtained orange-yellow flowable suspension liquid is weighed and packaged to obtain the finished product.

Embodiment 3

[0050] Example 3: 10.03% matrine-brassinolide suspension seed coating

[0051] Matrine 10%

[0052] Brassinolide 0.03%

[0053] Sodium lignosulfonate 3%

[0054] Alkyl naphthalene sulfonic acid formaldehyde condensate sodium salt 5%

[0055] Styrylphenyl ethoxylate 2%

[0056] Glycerol 5%

[0057] Magnesium Aluminum Silicate 1.0%

[0058] Seed coating film former (853) 3%

[0059] 2% Xanthan Gum 5%

[0060] Bentonite 3%

[0061] Sorbic acid 0.2%

[0062] Acid Red B 2%

[0063] Defoamer 0.5%

[0064] Mold inhibitor 10%

[0065] Water to make up to 100%

[0066] According to the formula requirements, with water as the medium, 300 kg of matrine, 0.9 kg of brassinolide, 90 kg of sodium lignosulfonate, 150 kg of alkyl naphthalene sulfonate formaldehyde Condensate sodium salt, 60 kg styrylphenyl polyoxyethylene ether, 150 kg glycerin, 30 kg magnesium aluminum silicate, 90 kg seed coating agent film-forming agent (853), 90 kg bentonite, 6 kg sorbic acid , 60 kg of aci...

Abstract

The invention discloses a matrine-brassinolide suspension seed coating agent which is used for processing seeds, and a preparation method thereof. The content of matrine is 0.01 to 80%, and the content of brassinolide is 0.001 to 10%. The preparation method comprises following steps: matrine, brassinolide, a dispersant, an antifreezing agent, a film forming agent, a filling material, a colouring agent, a pH conditioning agent and sufficient deionized water are added into a high shear emulsion-dispersion machine; the mixture is stirred uniformly, and is added into a sand mill for grinding; an aqueous solution prepared by the pH conditioning agent and a thickening agent is added to adjust the pH value and viscosity; and then the obtained solution is stirred uniformly and discharged so as to obtain the matrine-brassinolide suspension seed coating agent. The matrine-brassinolide suspension seed coating agent is mainly used for seed coating processing of crops such as rice, wheat, corn, cotton, soybean, peanut, beet, and sunflower before plantation; and possesses significant effects in preventing and curing underground injurious insects, crop injurious insects, and soil born diseases, and promoting the growth of plants. The matrine-brassinolide suspension seed coating agent can be used for manual coating and mechanical coating, and is capable of saving time and labor. Environment pollution caused by the matrine-brassinolide suspension seed coating agent and the application technology is less than that caused by seed coating agents of other dosage forms and other application technologies; and utilization ratio of pesticides is high.

Description

technical field [0001] The invention relates to a seed treatment agent for repelling pests, preventing and controlling diseases, strengthening seedlings, and promoting growth adjustment for crops and a preparation method thereof, in particular to a matrine-brassinolide suspension seed coating agent for treating seeds The preparation method thereof belongs to the field of biochemical pesticides. Background technique [0002] Seed coating agent is a new type of pesticide formulation composed of pesticide original drug, film forming agent, filler and related auxiliaries.
