Problems solved by technology

However, the processed preparations are all emulsifiable concentrate products with toluene or xylene as solvents. Although the emulsifiable concentrate has good insecticidal effect and is convenient to use, because it contains a large amount of toxic aromatic hydrocarbon organic solvents, these solvents are unavoidable. Pollution hazards to the agricultural environment and agricultural products

Embodiment 1

[0024] Product composition ①Active ingredients: imidacloprid 1%, cypermethrin 4%; ②solvent: DMF 8%, cyclohexanone 15%; ③surfactant: Nongru 500 5%, Nongru 600 8%, Nongru 1600 No. 5%; ④ co-surfactant: n-butanol 3%; ⑤ antifreeze: ethylene glycol 2%, the balance of tap water.

[0025] Preparation method: add imidacloprid raw powder into a reactor with stirring, then add DMF, stir, after imidacloprid is completely dissolved, add cypermethrin and cyclohexanone, stir to obtain imidacloprid-cypermethrin mixed solution, then add commercially available Nongru 500 No., No. 600, No. 1600, n-butanol, ethylene glycol, stir the organic phase uniformly, add the remainder of tap water to the organic phase and stir for 10-30 minutes under the same stirring conditions to obtain 5% imidacloprid-cypermethrin microemulsion product.

Embodiment 2

[0027] Repeat embodiment 1, have the following differences: 1. active ingredient: imidacloprid 2%, cypermethrin 10%; 2. cosolvent: dimethyl sulfoxide 6%, epichlorohydrin 10%; Sodium acid 5%, Nongru No. 33 10%, Nongru 16016%; ④ co-surfactant: isopropanol 4%; ⑤ antifreeze: glycerol 3%, tap water balance.

Embodiment 3～8

[0029] The preparation process is the same as in Example 2, except that the surfactant is anionic surfactant calcium dodecylbenzenesulfonate 5% and one selected from nonylphenol polyoxyethylene ether, nonylphenol polyoxyethylene polyoxypropylene ether , Alkylphenol polyoxyethylene polyoxypropylene ether block copolymer, alkylphenol polyoxyethylene ether formaldehyde condensate, phenethylphenol polyoxyethylene ether, a nonionic alkylphenol polyoxyethylene ether phosphate ester Surfactants are used in combination, and the amount of nonionic surfactants is 12%.

Abstract

An insecticiding microemulsion is prepared through dissolving inmidacloprid and cypermethrin in cosolvent, sequentially adding surfactant, surfactant aid and antifreezing agent, stirring and adding clean water.

Description

technical field [0001] The present invention relates to pesticide insecticide, more specifically, the present invention relates to a kind of insecticidal microemulsion composition. At the same time, the invention also relates to a preparation method of the insecticidal microemulsion composition. Background technique [0002] In order to produce enough agricultural products from limited land, in modern agricultural production, whether it is pre-production, production or post-production, pesticides are indispensable and important means of production. However, with the widespread use of pesticides in large quantities, people's worries and worries about the safety of pesticides are becoming more and more serious. Based on this situation, the development of new products with high activity or even ultra-high activity, low toxicity, low residue and environmental friendliness has become the goal pursued by pesticide scientists from all over the world and ha...
