Embodiment 1

[0017] Example 1, add 10g silver fruit crude oil, add 0.5g calcium dodecylbenzenesulfonate, 0.5g styrene ethylphenol polyoxyethylene polyoxypropylene ether, 3g castor oil, 4g tristyrylphenol polyoxyethylene ether , 7g of xylene, heated to 70°C while stirring continuously, then added 15g of water, and set aside; 8g of gelatin and 8g of sodium alginate were added to 92g of water for hydrolysis, respectively heated to 70°C, and the above hydrolyzed glue was taken Filter each 24g, mix after filtering, and stir evenly, add the well-stirred glue solution to the spare solution prepared above, mix and stir at a speed of 400 rpm, and cool down naturally for 2 hours to get the silver fruit microcapsule suspoemulsion.

[0018] The silver fruit microcapsule suspoemulsion of the above-mentioned embodiment and 10% silver fruit EC are compared in Table 1 for the drug effect persistence period of preventing and treating tomato botrytis cinerea.

[0019] Test sample

Embodiment 2

[0020] Embodiment 2, 5g silver fruit crude oil, add 0.2g calcium dodecylbenzenesulfonate, 0.2g castor oil ethylene oxide adduct, 2g castor oil, 3g dibianyl biphenol polyoxyethylene ether, 6g Xylene, heated to 60°C, while stirring continuously, then added 10g of water, set aside; 8g of starch glue, 8g of sodium alginate were added to 92g of water for hydrolysis, respectively heated to 60°C, and the above-mentioned hydrolyzed glue solutions were 20g to filter, filter and mix, and stir evenly, add the well-stirred glue solution to the spare solution prepared above, mix and stir at a speed of 300 rpm, and cool down naturally for 2 hours to get the silver fruit Capsule suspoemulsion.

Embodiment 3

[0021] Example 3, 15g silver fruit crude oil, add 1g styrene ethylphenol polyoxyethylene polyoxypropylene ether, 1g castor oil ethylene oxide adduct, 5g castor oil, 5g tristyrylphenol polyoxyethylene ether, Heat 8g of xylene to 80°C while stirring continuously, then add 20g of water and set aside; add 8g of gelatin and 8g of starch glue to 92g of water for hydrolysis, respectively heat to 80°C, and take 30g of the above-mentioned hydrolyzed glue solutions Filter, mix after filtering, and stir evenly, add 1g foaming agent, add the well-stirred glue solution to the spare liquid prepared above, mix and stir at a speed of 600 rpm, and cool down naturally for 2 hours, That is, silver fruit microcapsule suspoemulsion is obtained.

Abstract

A suspension-emulsion of silverberry is prepared through respectively hydrolyzing the animal glue, plant gum and sea product gelatin, heating to 60-80 deg.C, filtering, mixing to obtain the mixture, proportionally mixing, silverberry oil, assistant, plant oil, surfactant and solvent, heating to 60-80 deg.C while stirring, adding water and said mixture, stirring at 300-600 rpm, and naturally cooling for 2 hr. Its advantage is high effect.

Description

(1) Technical field: [0001] The invention relates to the technical field of pesticide formulations, in particular to a silver fruit microcapsule suspoemulsion and a preparation method thereof. (two) background technology: [0002] Biomimetic botanical fungicide is artificially synthesized bionic botanical fungicide based on the bactericidal structural formula of Ginkgo biloba extract. It has low toxicity, high efficiency, no residue, and no harm to natural enemies. It is the first choice for pollution-free fungicides, but the medicine smells The smell is too strong, and it will cause severe corrosion to the decomposition of the package. At present, the packaging polyester bottle and plastic bottles made of various plastics cannot bear its stimulation, and the packaging is difficult. (3) Contents of the invention: [0003] The purpose of the present invention aims to overcome the above-mentioned deficiencies in the prior art, and a kind of silver fruit microcapsule suspoemu...
