Embodiment 1

[0016] According to the technical scheme of the present invention, weigh 1% of indoxacarb original drug, 8% of solvent and co-solvent xylene, and 5% of pyrrolidone. After the three are fully mixed and dissolved, add emulsifier castor oil polyoxyethylene ether 10%, Polyol fatty acid ester and its ethylene oxide adduct 4%, wetting agent fatty alcohol polyoxyethylene ether 4%, penetrant sodium alkylbenzene sulfonate 2%, after fully stirring and dissolving, deionized water is added to 100%, continue stirring until transparent to prepare 1% indoxacarb microemulsion.

Embodiment 2

[0018] According to the technical scheme of the present invention, take by weighing 5% of the original drug of indoxacarb, 10% of toluene, 6% of cyclohexanone, and 5% of phosphate ester. After fully mixing and dissolving, add 4% of alkylphenol polyoxyethylene ether, benzene Vinylphenol polyoxyethylene ether 2%, sodium dioctyl maleate sulfonate 6%, sodium sulfate 0.1%, sodium lauryl sulfate 1%, sodium dialkyl succinate sulfonate 2%, after fully stirring and dissolving, make up 100% with deionized water, and continue stirring until transparent to prepare 5% indoxacarb microemulsion.

Embodiment 3

[0020] According to the technical scheme of the present invention, take indoxacarb former medicine 10%, C 10 Solvent oil S-200 10%, pyrrolidone 8%, n-butanol 2%, after fully mixing and dissolving, then add maleic acid di-sec-octyl sulfonate 6%, polyol fatty acid ester and its ethylene oxide 8% alkane adduct, 2% alkylphenol polyoxyethylene ether sulfate, 3% alkylpyridine halide, after fully stirring and dissolving, make up 100% with water, continue stirring until transparent, and prepare 10% indoxacarb emulsion.

Abstract

The invention discloses an indoxacarb microemulsion and a preparation method thereof. The indoxacarb microemulsion comprises components of, in weight percentage: 1-15% of indoxacarb, 5-40% of cosolvent and solvent, 3-15% of emulsifier, 1-5% of wetting agent, 1-5% of penetrating agent and the balance of deionized water. The preparation method comprises steps of: completely dissolving the indoxacarb in solvent and cosolvent; then adding a certain proportion of emulsifier, wetting agent and penetrating agent into a preparation vessel, and mixing evenly; and finally adding deionized water, and mixing evenly to obtain the indoxacarb microemulsion. The invention adopts a reasonable processing technology to obtain the indoxacarb microemulsion product with stable quality, good dispersion performance and storage resistance.

Description

technical field [0001] The invention relates to an agricultural insecticide indoxacarb microemulsion and a preparation method thereof, belonging to the field of agricultural chemistry. Background technique [0002] Indoxacarb disables the function of insect nerve cells by blocking sodium ion channels in insect nerve cells. Indoxacarb has contact and stomach poisoning effects, and is effective for all instar larvae. It can effectively control a variety of pests on crops such as grain, cotton, fruit, and vegetables, and there is no cross-resistance with other insecticides. It has low toxicity to mammals and livestock, and is very safe to beneficial insects such as non-target organisms in the environment. It has low residue in crops and can be harvested within 2 days after application. It is suitable for controlling beet armyworm, diamondback moth, Cabbage caterpillar, Spodoptera litura, Cabbage Spodoptera, Cotton Bollworm, Cabbage Budworm, Leaf Roller Moth, Apple Stupid Mot...
