Problems solved by technology

[0003] At present, the dosage forms of indoxacarb insecticide products used in the pesticide market are mainly water-dispersible granules. However, if the control effect of indoxacarb water-dispersible granules is to reach a higher level, the application amount needs to be increased. This puts a lot of pressure on the environment

Embodiment 1

[0023] Embodiment 1: 5% indoxacarb microemulsion

[0024]

[0025] Dissolve indoxacarb with cyclohexanone as a solvent and n-butanol as a cosolvent, then add Nongru No. 33 and emulsifier NP-10-P and mix evenly, and finally add distilled water and stir well to form a microemulsion.

[0026] The indoxacarb microemulsion prepared in this example was tested for physical and chemical properties, and the results were as follows:

[0027] Appearance: clear and transparent single-phase liquid;

[0028] Transparent temperature area: minus 5°C to above 60°C;

[0029] Low temperature stability: no delamination and crystallization at -5°C for 2 weeks;

[0030] Thermal storage stability: the decomposition rate of active ingredients is less than 3% at (54±2)°C for 2 weeks;

[0031] Emulsion stability: Emulsion diluted with any proportion of water is stable;

[0032] Stability over time: Stable at room temperature.

Embodiment 2

[0033] Embodiment 2: 30% indoxacarb microemulsion

[0034]

[0035] Dissolve indoxacarb with solvent methanol and co-solvent ethanol, then add Nongru 0201B and mix evenly, and finally add distilled water, stir well to form a microemulsion.

[0036] The indoxacarb microemulsion prepared in this example was tested for physical and chemical properties, and the results were as follows:

[0037] Appearance: clear and transparent single-phase liquid;

[0038] Transparent temperature area: minus 5°C to above 60°C;

[0039] Low temperature stability: no delamination and crystallization at -5°C for 2 weeks;

[0040] Thermal storage stability: the decomposition rate of active ingredients is less than 3% at (54±2)°C for 2 weeks;

[0041] Emulsion stability: Emulsion diluted with any proportion of water is stable;

[0042] Stability over time: Stable at room temperature.

Embodiment 3

[0043] Embodiment 3: 10% indoxacarb microemulsion

[0044]

[0045] Dissolve indoxacarb with xylene as a solvent and propanol as a cosolvent, then add Nongru No. 500 and Nongru No. 600 and mix evenly, and finally add distilled water and stir well to form a microemulsion.

[0046] The indoxacarb microemulsion prepared in this example was tested for physical and chemical properties, and the results were as follows:

[0047] Appearance: clear and transparent single-phase liquid;

[0048] Transparent temperature area: minus 5°C to above 60°C;

[0049] Low temperature stability: no delamination and crystallization at -5°C for 2 weeks;

[0050] Thermal storage stability: the decomposition rate of active ingredients is less than 3% at (54±2)°C for 2 weeks;

[0051] Emulsion stability: Emulsion diluted with any proportion of water is stable;

[0052] Stability over time: Stable at room temperature.

Abstract

The invention relates to the field of pesticide preparation and discloses an indoxacarb microemulsion and a preparation method of the indoxacarb microemulsion. The indoxacarb microemulsion provided by the invention comprises the following ingredients in percentage by weight (accounting for the total weight of the microemulsion): 1 to 30 percent of indoxacarb, 10 to 20 percent of solvents, 10 to 30 percent of emulsifying agents, 0.5 to 10 percent of cosolvents and the balance water. The indoxacarb microemulsion provided by the invention has the advantages that the cost is low, the preparation process is simple, the package requirement is low, meanwhile, the consumption of organic solvents is reduced, the residue is little, the environment pollution is little, in addition, the prevention effect is higher than that of indoxacarb water dispersible granules, the medication quantity can be reduced, and the indoxacarb microemulsion is suitable for large-area popularization.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to an indoxacarb microemulsion and a preparation method thereof. Background technique [0002] Indoxacarb (Indoxacarb), the chemical name is 7-chloro-2,5-dihydro-2-[N-(methoxyformyl)-4-(trifluoromethoxy)anilinoyl]indeno[ 1,2-e][1,3,4]oxadiazine-4a(3H)-methyl formate is an oxadiazine sodium channel blocker developed and developed by DuPont Company of the United States. It has contact and stomach toxicity , by blocking the sodium ion channel in the nerve cells of insects, the nerve cells are disabled, and it is effective against almost all lepidopteran pests. The medicine enters the insect body through contact and feeding, and the insect stops feeding within 0-4 hours, and then is paralyzed, and the coordination ability of the insect will decrease (which can cause the larvae to fall from the crop), generally within 24-60 hours after the medicine die. It is suitable for control...
