Embodiment 1

[0020] A kind of production method of emamectin benzoate granule mainly is the former medicine of emamectin benzoate and dispersion agent, wetting agent (sulfonate surfactant), Binders (glucose and lactose), disintegrants (thiamine) and fillers are fully mixed and powdered to the target particle size to form finished granules. Specific steps are as follows:

[0021] 1) Mixing and powdering: close the bottom valve of the mixer, open the feed port of the mixer, put in 20kg of the original drug of emamectin benzoate, and 8kg of dispersant (the dispersant is mainly polycarboxylate and naphthalenesulfonic acid Salt), wetting agent 4kg, disintegrant 23kg, binder 8kg and filler 37kg (the filler in this project is mainly corn starch), and the feeding is completed and stirred for 60min; The coarse powder is collected into the middle hopper, and then the jet mill is turned on for crushing. The screw feeding frequency is 8Hz, the jet mill pressure is 0.8MPa, the jet mill frequency is 50...

Embodiment 2

[0024] A kind of production method of emamectin benzoate granule, concrete steps are as follows:

[0025] 1) Mixing and powdering: close the bottom valve of the mixer, open the feed port of the mixer, put in 23kg of the original drug of emamectin benzoate, and 8kg of dispersant (the dispersant is mainly polycarboxylate and naphthalenesulfonic acid Salt), wetting agent 4kg, disintegrant 25kg, binder 10kg and filler 30kg (the filler in this project is mainly corn starch), and the feeding is completed and stirred for 60min; The coarse powder is collected into the middle hopper, and then the jet mill is turned on for crushing. The screw feeding frequency is 8Hz, the jet mill pressure is 0.8MPa, the jet mill frequency is 50Hz, and the crushing particle size is controlled to 8-10μm.

[0026] 2) Granulation and drying: Put the pulverized material into the mixer, spray 5kg of deionized water, stir for 30 minutes, and then discharge it to the conveyor belt, transfer it to the hopper of...

Embodiment 3

[0028] A kind of production method of emamectin benzoate granule, concrete steps are as follows:

[0029] 1) Mixing and powdering: close the bottom valve of the mixer, open the feed port of the mixer, put in 25kg of the original medicine of emamectin benzoate, and 10kg of dispersant (the dispersant is mainly polycarboxylate and naphthalenesulfonic acid Salt), wetting agent 4kg, disintegrant 23kg, binder 8kg and filler 30kg (the filler in this project is mainly corn starch), and the feeding is completed and stirred for 60min; The coarse powder is collected into the middle hopper, and then the jet mill is turned on for crushing. The screw feeding frequency is 8Hz, the jet mill pressure is 0.8MPa, the jet mill frequency is 50Hz, and the crushing particle size is controlled to 8-10μm.

[0030] 2) Granulation and drying: Put the pulverized material into the mixer, spray 5kg of deionized water, stir for 30 minutes, and then discharge it to the conveyor belt, transfer it to the hoppe...

Abstract

The invention discloses an emamectin benzoate granule and a preparation method of same. The emamectin benzoate granule is composed of, by weight, 20-30 parts of an emamectin benzoate active compound, 6-10 parts of a dispersant, 2-5 parts of a wetting agent, 20-25 parts of a disintegrating agent, 5-10 parts of a binder, and 20-47 parts of filler. The preparation method has simple process and operations and is high in utilization rate on the emamectin benzoate active compound. The emamectin benzoate granule is easy to package and convenient to transport, has excellent effect and has good practicability.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an emamectin benzoate granule and a production method thereof. Background technique [0002] Emamectin benzoate is a new type of high-efficiency semi-synthetic antibiotic insecticide synthesized from the fermentation product abamectin B1. It has ultra-high efficiency, low toxicity (preparation is almost non-toxic), low residue, Pollution-free and other characteristics of biological pesticides. It is widely used in the control of various pests on vegetables, fruit trees, cotton and other crops. This product is currently the only new, highly efficient, low-toxic, safe, pollution-free, and residue-free biological insecticide and acaricide that can replace five highly toxic pesticides in the world. Highest activity, wide insecticidal spectrum, no drug resistance. Emamectin benzoate can enhance neuroticism such as glutamic acid and γ-aminobutyric acid (GABA), so that...
