Embodiment 1

[0012] Embodiment 1: Calculate based on the finished product-water emulsion weight 100%, 0.6% Abamectin is dissolved with 1% cyclohexanone earlier, then add 8% mineral spirits and keep stirring until forming a uniform oil phase. Then 4.5% of 1602#, 0.5% of alkylbenzenesulfonate calcium emulsifier, 2% of ethylene glycol, 0.3% of azone, 1% of aluminum magnesium silicate, 0.05% of organic silicon defoamer, 0.5% BHA was dissolved in water and made up to 100% with water, stirring continuously until a homogeneous liquid was formed as the aqueous phase. When the speed of the high-speed shearing machine is 2000-3000 rpm, slowly pour the water phase into the oil phase, then increase the speed to 8000-10000 rpm, stir for 40 minutes, and shear and disperse evenly to form a milky white The emulsion is the abamectin water emulsion used in aquaculture.

[0013] Its physical and chemical performance indicators are as follows:

[0014] Abamectin content, % 0.6

[0015] pH value 5.2~6.8

Embodiment 2

[0023] Embodiment 2: Calculate based on the finished product-water emulsion weight 100%, 1% Abamectin is dissolved with 10% solvent naphtha, keep stirring until forming a uniform oil phase. Then 2% of NP-10, 4% of tristyrylphenol polyoxyethylene ether emulsifier, 1.5% of glycerin, 0.5% of azone, 0.8% of gum arabic, 0.1% of silicone defoamer, 0.8% BHA was dissolved in water and made up to 100% with water, stirring continuously until a homogeneous liquid was formed as the aqueous phase. When the speed of the high-speed shearing machine is 2000-3000 rpm, slowly pour the water phase into the oil phase, then increase the speed to 12000 rpm, stir for 30 minutes, and shear and disperse evenly to form a milky white emulsion That is, the abamectin aqueous emulsion used in aquaculture.

[0024] Its physical and chemical performance indicators are as follows:

[0025] Abamectin content, % 1.0

[0026] pH value 5.2~6.8

[0027] Excellent water dispersibility

Embodiment 3

[0034] Embodiment 3: Calculate based on the finished product-water emulsion weight 100%, 2% Abamectin is dissolved with 2% cyclohexanone earlier, then add 10% mineral spirits and keep stirring until forming a uniform oil phase. Then add 4% of 1602#, 5% of tristyrylphenol polyoxyethylene ether, 1% of phosphate emulsifier, 2% of propylene glycol, 1% of azone, 1% of xanthan gum, 0.15% of Dissolve silicone defoamer, 1% BHA in water and make up to 100% with water, keep stirring until forming a uniform liquid, as the water phase. When the speed of the high-speed shearing machine is 2000-3000 rpm, slowly pour the water phase into the oil phase, then increase the speed to 15000 rpm, stir for 20 minutes, and shear and disperse evenly to form a milky white emulsion That is, the abamectin aqueous emulsion used in aquaculture.

[0035] Its physical and chemical performance indicators are as follows:

[0036] Abamectin content, % 2.0

Abstract

The invention provides an abamectin aqueous emulsion for aquaculture, which relates to the abamectin aqueous emulsion for preventing and treating parasitic diseases of aquatic animals. The problem to be solved is to provide the abamectin aqueous emulsion for aquaculture, which has the advantages of high anthelmintic activity, safety, environmental protection and low cost. The abamectin aqueous emulsion is characterized by comprising the following components (based on 100 percent weight of abamectin aqueous emulsion) in percentage by weight: 0.6 to 2 percent of abamectin, 9 to 20 percent of solvent, 5 to 15 percent of emulsifier, 0.3 to 1 percent of a penetrant, 0.5 to 3 percent of thickener, 1 to 5 percent of antifreeze agent, 0.05 to 0.2 percent of defoamer, 0.1 to 1 percent of chemical stabilizer, and the balance of water up to 100 weight percent. The aqueous emulsion is used for preventing and treating nematode, in-vitro fish flea, fish louse and other parasitic diseases in bodies of the aquatic animals.

Description

Technical field: [0001] The invention relates to an abamectin aqueous emulsion for preventing and treating parasitic diseases such as aquatic animal nematodes, fish lice and fish fleas. Background technique [0002] In recent years, the frequent outbreaks of parasitic diseases in aquatic animals such as the anchor head fish flea, Chinese fish flea, finger ringworm, and wheel wheel have caused great economic losses to aquaculture in our country. Abamectin is a macrolide antiparasitic drug produced by Streptomyces avermitilis. It has a strong repellent effect on nematodes, fish lice, and fish fleas. It has been widely used in aquatic animals for internal and external parasites Disease prevention and control, and reduce the dosage of anti-helminth drugs from mg / kg level to μg / kg level. [0003] As a new type, broad-spectrum, high-efficiency, safe and low dosage biopesticide, abamectin is considered to have good prospects and broad development space. However, because it is a f...
