Embodiment 1

[0029] 0.5g of 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate at 40°C Dissolve in 99.5g isopropyl myristate while stirring to obtain light yellow transparent insecticide mother liquor, wherein the active ingredient 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-3- The weight percentage of (2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylate is 0.5%.

Embodiment 2

[0031] 5g of 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate at 40°C Dissolve in 90.8 g of diisopropyl adipate while stirring, stir for another 30 minutes after it completely dissolves, and cool to room temperature. Then add 4g synergamine, 0.2gBHT, mix well, obtain light yellow transparent insecticide mother liquor, wherein active ingredient 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-3-( The weight fraction of 2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylate is 5%, and the weight fraction of synergist amine is 4%.

Embodiment 3

[0033] 10g of 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-1R, trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate The acid ester was dissolved in a homogeneously mixed solution of 44.9 g of n-butyl adipate and 44.9 g of diisopropyl adipate while stirring at 50° C. After it was completely dissolved, it was stirred for another 40 minutes and cooled to room temperature. Then add 0.2gBHT, mix well, obtain light yellow transparent insecticide mother liquor, wherein active ingredient 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl-1R, trans-3-( The weight fraction of 2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylate is 15%.

Abstract

The invention provides insecticide mother liquor comprising the components by weight: active ingredient A and solvent B represented by the right formula. The solvent B comprises one or more than two components from monobasic acid ester, dicarboxylic ester or tricarboxylic ester containing 8-20 carbon atoms. A accounts for 0.1-40% of the total weight of A and B. The total weight of A and B accounts for 88-100% of the mother liquor total weight. B greatly increases the insecticidal activity of A. The insecticide mother liquor has higher insecticidal activity.

Description

technical field [0001] The invention relates to an insecticide mother liquor and its application. Background technique [0002] In the Chinese patent CN101306997A, the application of pyrethroid compounds with the following structure in the prevention and control of sanitary pests is disclosed. However, in the technical solution of this invention, conventional odorless kerosene solvent is used for dissolving, not only the amount of kerosene required is very large, but also other Co-solvent; In addition, the insecticidal activity of this insecticide mother liquor formulated with kerosene is also low. [0003] Contents of the invention [0004] The object of the present invention is to overcome the defects that the existing kerosene-prepared insecticide mother liquor needs a large amount of solvent and added co-solvent for dissolution, and has low insecticidal activity. [0005] The present invention realizes above-mentioned purpose through following technical scheme: ...
