Problems solved by technology

[0002] Amitraz raw powder is insoluble in water, but soluble in various organic solvents such as xylene, acetone and methanol. These organic solvents are highly toxic, highly carcinogenic, and have high residues. Most of them are harmful to the human nervous system, liver function damage, hematopoietic system, Mucous membrane and skin irritation and other serious health threats
At the same time, organic solvents have many safety and environmental protection problems such as flammable, explosive, easy to diffuse, large environmental pollution and difficult to degrade, and there are great safety hazards in the process of production and transportation.

Embodiment 1

[0027] A water-soluble insecticide containing amitraz, preferably comprising the following components in mass percentage: amitraz 12.75%,

[0028] Co-solvent 76%, quaternary ammonium salt 6.25%, synergist 5%. The preparation method of the above-mentioned water-soluble insecticide containing amitraz, the steps are:

[0029] Solvent sample 1: Mix amitraz and co-solvent and stir for 20 minutes, then add quaternary ammonium salt and synergist into the stirring tank and stir for 20 minutes, and then discharge to obtain the finished product.

[0030] Reagents and medicines used in the examples are commercially available routine products, in the following examples:

[0031] Decomposition rate calculation formula: Decomposition rate% = (content before storage - content after thermal storage or normal temperature storage) / content before storage × 100%

[0032] The content before storage is the content of the original drug detected when the sample is prepared for storage (54±2°C) fo...

Embodiment 2

[0045] Solvent sample 2: Weigh 12.75kg of amitraz and 66kg of co-solvent, mix and stir for 20 minutes, then add 6.25kg of quaternary ammonium salt and 15kg of synergist into the stirring tank and stir for 20 minutes, and the material is discharged to obtain 100kg of this method Li example of water-soluble insecticides.

[0046] Control sample 1: Commercially available amitraz solution (content of 12.5%, amitraz solution with xylene as solvent, diluted with water to form a milky white emulsion.)

[0047] For the above samples, the determination of the content before storage, the stability test at room temperature and the heat storage test were carried out at the same time. The heat storage samples were placed in an oven at a temperature of 54±2°C for 14 days, and the samples at room temperature were placed for 12 months and 18 respectively. month and 24 months. Use gas chromatography to measure the content of amitraz in the samples before storage, heat storage samples and norm...

Abstract

The invention discloses a water-soluble insecticide with amitraz and a method for preparing the water-soluble insecticide, and belongs to the technical field of insecticide production. Raw materials for producing the water-soluble insecticide which is a product include, by weight, 10-20% of amitraz, 50-80% of co-solvents, 5-15% of quaternary ammonium salt and 2-8% of synergists. The water-solubleinsecticide and the method are characterized in that the amitraz and the co-solvents are mixed with one another and then are stirred for 20 minutes, then the quaternary ammonium salt and the synergists are added into stirring tanks and are stirred for 20 minutes, and discharge is carried out to obtain the water-soluble insecticide which is the finished product. The water-soluble insecticide and the method have the advantages that the product is non-flammable and non-explosive and is free of environmental pollution; the water-soluble insecticide is low in production cost; obvious synergistic effects can be realized; good insecticidal effects can be realized, and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide production, in particular to a water-soluble pesticide containing amitraz and a preparation method thereof. Background technique [0002] Amitraz raw powder is insoluble in water, but soluble in various organic solvents such as xylene, acetone and methanol. These organic solvents are highly toxic, highly carcinogenic, and have high residues. Most of them are harmful to the human nervous system, liver function damage, hematopoietic system, Mucous membrane and skin irritation and other serious health threats. At the same time, organic solvents have many safety and environmental protection problems such as flammability, explosion, easy diffusion, large environmental pollution and difficult degradation, and there are great safety hazards in the process of production and transportation. With the development of society and the improvement of safety production awareness, the state has introduced relev...
