Embodiment 1

[0034] The composition ratio of table 1 embodiment 1

[0035]

[0036] Add 25.5g of permethrin raw material to 5.0g of emulsifier NEWKALGEN FS-7 (Japanese Takemoto Oils and Fats) and stir evenly (oil phase); Add 15g of water phase and stir to form a milky white paste; add the mixed emulsion to the carrier silica and stir, adjust the pH value to about 6 with 0.1g of glacial acetic acid, 0.3g of silicone defoamer, wetting and dispersing agent Morwet EFW 2.0g was stirred evenly to form a kneaded pre-granulation mixture, which was then granulated by pan-type pressure and dried to obtain 25.5% permethrin EG.

Embodiment 2

[0038] The composition ratio of table 2 embodiment 2

[0039]

[0040] Add 27.9g of Daofengsan ester raw material to 2.0g of emulsifier NEWKALGEN SB-75 (Japanese Takemoto Oil) and stir evenly (oil phase); pour the configured oil phase into 10% water-soluble polymer PVA 4.5g of the water phase and stirred to form a milky white paste; the mixed emulsion was added to the carrier sodium benzoate and stirred, and the wetting and dispersing agent MorwetD-4258.0g was stirred evenly to form a kneading pre-granulation mixture, and then added by pan Press and granulate, dry and dry to obtain 27.90% Daofengsan EG.

Embodiment 3

[0042] The composition ratio of table 3 embodiment 3

[0043]

[0044]Dissolve 20.4g of flusilazole original drug with 5g of solvent oil, then add 5.0g of emulsifier YUS-FS7PG (Japanese bamboo oil) and stir evenly (oil phase); pour the prepared oil phase into 10% Add 10g of water-soluble polymer PVA to the water phase and stir to form a milky white paste; add the mixed emulsion to the carrier corn flour and stir, wetting and dispersing agent YUS-WG48.0g, PICO-NW12.0g, kaolin 10 g was stirred evenly to form a kneading pre-granulation mixture, which was then granulated by pan-type pressure and dried to obtain 17.1% flusilazole EG.

Abstract

The invention provides pesticide emulsifiable granules. The emulsifiable granules comprise: 0.1 to 30 weight parts of raw material of pesticide, 0 to 10 weight parts of solvent, 2 to 20 weight parts of emulsifying agent, 1 to 5 weight parts of water-soluble high molecular polymer, 10 to 80 weight parts of vector and 0.1 to 100 weight parts of water. The invention also provides a method for preparing the emulsifiable granules. In the method, high molecule coated granules are adopted in the process and formula to form the effective isolation, so the common thermal agglomeration problem in the developing process of emulsifiable granules EG is solved; and thus, the environment-friendly novel emulsifier pesticide product is formed.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to an emulsifiable granule and a preparation method thereof. Background technique [0002] The traditional pesticide formulation EC is to add pesticide raw materials to the EC, but because of the use of a large amount of organic solvents, it is easy to cause environmental pollution, and because of the organic solvents, there is a risk of burning during storage and transportation. Sex is poor. [0003] Another kind of pesticide formulation of wettable powder WP formulation will have dust flying and drifting. The pesticide preparations of these two dosage forms are relatively toxic and irritating to humans and animals, and have certain phytotoxicity to crops. [0004] Emulsifiable granules (Emulsifiable Graules, EG) are water-emulsifiable granules, which are made by dissolving or diluting active ingredients in a solvent and then adsorbing them on a suitable...
