Problems solved by technology

[0002] We have disclosed in Chinese patent CN101543225A a kind of insecticide mother liquor mainly based on active ingredient A and solvent component B in the present invention, but in later practical use we found that the insecticide prepared only with solvent component B The agent mother liquid is not stable when placed at a lower temperature. For example, it will become cloudy after 48 hours at 0°C, and crystals that are difficult to dissolve again are deposited at the bottom of the container, which makes it very inconvenient to use in cold regions.

preparation Embodiment 1

[0025] 0.5 g of 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate (1R , trans; 1R, cis; 1S, trans; 1S, cis four isomers each accounting for 25%) dissolved in 98.5g of isopropyl myristate and 1g of phthalic acid while stirring at 40°C In the mixed solution of diethyl ester, a light yellow transparent insecticide mother solution 1 is obtained, wherein the weight percentage of the active component A accounts for 0.5% of the total weight of the A, B, C ternary system.

preparation Embodiment 2

[0027] 5g 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-1R-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate ( 1R, trans: 1R, cis=8:2) was dissolved in a uniformly mixed solution of 60.4g diisopropyl adipate and 30.4g ethyl chrysanthemum acid while stirring at 40°C, and after it was completely dissolved Stir for another 30 minutes and cool to room temperature. Then add 4g synergamine, 0.2gBHT, mix well, obtain light yellow transparent insecticide mother liquor 2, wherein the weight percentage of active ingredient A accounts for 5% of the total weight of A, B, C ternary system.

preparation Embodiment 3

[0029] 15g of 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-1R, trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate Dissolve the acid ester in a uniformly mixed solution of 20.6g of diisopropyl adipate, 40.4g of tributyl citrate and 24g of methyl permethrin while stirring at 40°C, and stir for 30 minutes after it is completely dissolved , cooled to room temperature. Mix evenly to obtain light yellow transparent insecticide mother liquid 3, wherein the weight percentage of active component A accounts for 15% of the total weight of the A, B, C ternary system.

Abstract

The invention provides pesticide mother solution, a preparation method and an application thereof. The pesticide mother solution comprises the following components in percentage by weight: 0.1-40% ofactive ingredient A expressed in the formula Xa, 10-98.9% of solvent B of the mixture of one or more than two of glutaric acid diisopropyl ester, adipic acid diisopropyl ester, adipic acid-di-n-butylester, ethyl laurate, dodecanoic acid normal propyl ester, isopropyl myristate, tirbutyl citrate or acetyl tributyl citrate; 1-50% of another solvent ingredient C. The pesticide mother solution of theinvention still can maintain stability at low temperature, and can be more convenient for being used in cold regions.

Description

technical field [0001] The invention relates to an insecticide mother liquor and its preparation method and application. Background technique [0002] We have disclosed in Chinese patent CN101543225A a kind of insecticide mother liquor mainly based on active ingredient A and solvent component B in the present invention, but in later practical use we found that the insecticide prepared only with solvent component B The agent mother liquid is not stable when placed at a lower temperature. For example, it will become cloudy after 48 hours at 0°C, and crystals that are difficult to dissolve again are deposited at the bottom of the container, which makes it inconvenient to use in cold regions. [0003] In order to overcome this defect, we have selected diethylene glycol dibutyl ether, diethylene glycol monobutyl ether, and one or more of the ester compounds represented by formula X2, X3, and X4 through a large number of experiments. The mixture is used as solvent component C, an...
