example 1

[0028] Example 1 to the prevention and control method of astragalus powdery mildew

[0029] (1) 8 kg of fenxining, 20 kg of lime sulfur mixture, after reaching 325 mesh to 400 mesh, add 5 kg of wetting and dispersing agent sodium lauryl sulfate, 5 kg of naphthalene sulfonate, and 52 kg of urea; the selected penetrant is sulfonic acid Add 5 kg of ethanol to 10 kg of dioctyl succinate sodium salt, stir, and set aside;

[0030] (2) The mixture was mixed without gravity for 10 minutes, and the prepared mixture of ethanol and penetrant was added by spraying during the mixing process.

[0031] (3) extrusion granulation, drying at 75° C. to obtain dry granules with a particle diameter of 1 mm;

[0032] (4) After the dried granules are sieved, they are packaged to obtain soluble granules; oversized granules or dust and dedusting powder are returned

[0033] Re-granulate after mixing with virgin material in a gravity-free mixer.

[0034] The preventive effect is:

example 2

[0036] The control method of example 2 astragalus seed wasps

[0037] (1) 12kg of acetamiprid, 10kg of phoxim, and after reaching 325 mesh to 400 mesh, add 5kg of wetting and dispersing agent sodium lauryl sulfate, 5kg of naphthalenesulfonate, 22kg of urea, and 36kg of potassium sulfate; The selected penetrating agent is dioctyl sulfosuccinate sodium salt, add 5 kg of ethanol to 10 kg, stir, and set aside;

[0038] (2) The mixture was mixed without gravity for 10 minutes, and the prepared mixture of ethanol and penetrant was added by spraying during the mixing process.

[0039] (3) extrusion granulation, drying at 75° C. to obtain dry granules with a particle diameter of 1 mm;

[0040] (4) After the dried granules are sieved, they are packaged to obtain soluble granules; oversized granules or dust and dedusting powder are returned

[0041] Re-granulate after mixing with virgin material in a gravity-free mixer.

Abstract

The invention relates to the technical field of plant protection, specifically to a soluble granule for preventing and treating disease and insect damage to Radix Astragali. The invention provides the soluble granule with the advantages of stable properties, simple and smooth production process and no proneness to moisture absorption, and a preparation method thereof. The soluble granule is prepared from water-insoluble or water-microsoluble pesticide effective ingredients and composed of effective ingredients, a wetting dispersant, an osmotic agent and a filling material, so the problem of easy decomposition of pesticide effective ingredients in a solvent is overcome.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a soluble granule for preventing and treating diseases and insect pests of Astragalus membranaceus. Background technique [0002] Astragalus insect pest control Among the many pests of Astragalus, there are three types that are seriously harmful and cause large economic losses: borers, turnips and aphids. The borer insects that harm Astragalus membranaceus are mainly Astragalus seed wasps, followed by four kinds of pests such as bean pod borer, alfalfa, noctuid moth, cotton bollworm, and cabbage worm; powdery mildew, rust, root rot, and white silkworm often occur in the diseases of Astragalus membranaceus , Blight, Fusarium wilt, Astragalus purple feather disease and so on. [0003] Commonly used pesticide formulations, such as powders, wettable powders, emulsifiable concentrates, suspension concentrates, etc., after use, the active ingredients are fully exposed in the ...
