Embodiment 1

[0008] Example 1: Using the finished product-water emulsion as 100% by weight, 0.1% of abamectin was mixed with 3% methanol solvent, stirred for 2 hours at a temperature of 30°C, and diluted and dissolved, and then 5% 600# was added. Emulsifier, 5% ethylene glycol antifreeze, 0.05% silicone defoamer and water make up to make the total weight of the above raw materials reach 99%, stir for 2 hours at a temperature of 25 ℃, after high shear After the cutting emulsifier shears and disperses evenly, add 1% aluminum magnesium silicate thickener, stir evenly at room temperature for 1 hour to make an emulsion, and then pass through the high shear emulsifier at room temperature for 1 hour to shear and disperse evenly , Which is made into insecticidal water emulsion containing abamectin.

[0009] Its various physical and chemical performance index values ​​are as follows:

[0010] Abamectin B 1 Mass fraction,% 0.1

[0011] PH value 4.5~7.0

[0012] Pourability: residue after dumping,% ≤ 6.0...

Embodiment 2

[0018] Example 2: Calculating the finished product-water emulsion as 100% by weight, dissolve 0.5% of abamectin in 8% ethanol, stir for 2 hours at a temperature of 30°C and dilute and dissolve, then add 8% 700# Emulsifier, 4% glycerol antifreeze, 0.08% silicone defoamer and water make up to make the total weight of the above raw materials reach 99.2%, stir for 2 hours at a temperature of 25 ℃, after high shear After the cutting emulsifier shears and disperses evenly, add 0.8% aluminum magnesium silicate thickener, stir uniformly at room temperature for 1 hour to make an emulsion, and then pass through a high shear emulsifier at room temperature for 1 hour to shear and disperse evenly , Which is made into insecticidal water emulsion containing abamectin.

[0019] Its various physical and chemical performance index values ​​are as follows:

[0020] Abamectin B 1 Mass fraction,% ≥ 0.5

[0021] PH value 4.5~7.0

[0022] Pourability: residue after dumping,% ≤ 6.0

Embodiment 3

[0028] Example 3: Taking the finished product-water emulsion as 100% by weight, 1% of abamectin was dissolved in 10% cyclohexanone and stirred for 2 hours at a temperature of 30°C, and then 10% of NP was added -10 emulsifier, 3% propylene glycol antifreeze, 0.1% silicone defoamer and water to make up to 99.4%, stir for 2 hours at a temperature of 25 ℃, shear and disperse uniformly, add 0.6% of yellow The original gum thickener, stirred uniformly for 1 hour at room temperature, and then sheared and dispersed evenly through a high-shear emulsifier to prepare an insecticidal water emulsion containing abamectin.

[0029] Its various physical and chemical performance index values ​​are as follows:

[0030] Abamectin B 1 Mass score,% 1

[0031] PH value 4.5~7.0

[0032] Pourability: residue after dumping,% ≤ 6.0

[0033] Residue after washing,% ≤ 2.0

[0034] Emulsion stability (diluted 200 times) qualified

[0035] Long lasting foaming (after 1min), ml ≤ 60

Abstract

The present invention discloses an insecticidal aqueous emulsion containing abamectin. Its composition contains (by wt%) abamectin 0.1-5%, emulsifier 5-25%, antifreezing agent 1-5%, defoaming agent 0.05-0.2%, solvent 3-35%, thickening agent 0.5-1% and the rest is water. It can be extensively used for killing antagonistical pests of cabbage moth, leaf miner and red mite, etc. on the vegetables, tangerine and cotton, etc.

Description

Technical field [0001] The invention relates to an insecticidal water emulsion containing abamectin, in particular to an insecticidal water emulsion containing abamectin for plant protection. Background technique [0002] There are many types of insecticides for plant protection, and emulsifiable concentrates and wettable powders are generally used. It is well known that emulsifiable concentrates contain a large amount of organic solvents, are prone to volatilization, are toxic to humans and plants, pollute the environment, and are inconvenient to transport; wettable powders have a large amount of dust during production and use, polluting the environment and affecting the health of operators. Summary of the invention [0003] The present invention overcomes the shortcomings in the prior art and provides a safe and environmentally friendly insecticidal water emulsion containing abamectin. [0004] In order to solve the above technical problems, the present invention is achieved t...
