preparation example Construction

[0062] As an embodiment of the present invention, the preparation method of the compound of formula 1 may include:

[0063] Dissolve 0.04mol (4.88g) of p-hydroxybenzaldehyde and 0.04mol (4.16g) of sodium bisulfite in 40ml of aqueous ethanol (ethanol: water = 1:1), and stir at room temperature for 0.5h. After suction filtration, 7.7 g of sodium p-hydroxybenzenemethanesulfonate was obtained, with a yield of 86%.

[0064] Dissolve 0.01mol (2.26g) sodium p-hydroxybenzenemethanesulfonate and 0.01mol (1.08g) o-phenylenediamine in 30ml of DMF, and reflux for 2h; then pour the reaction mixture into ice, suction filter, and re- Crystallization gave 1.14g of 2-(2-hydroxybenzene)-1hydro-benzimidazole with a yield of 54%.

[0065] Dissolve 4mmol (0.84g) of 2-(2-hydroxybenzene)-1hydro-benzimidazole and 4mmol (0.42g) of triethylamine in 8ml of dichloromethane, and cool to -5°C in an ice-salt bath. Dissolve 4mmol (0.92g) of 3-methyl-2(4-chlorophenyl)-butyryl chloride in 8ml of dichlorometh...

Abstract

The invention discloses a synergetic mixture, a synergetic composition and application thereof. The synergetic mixture comprises a component (a) and a component (b), wherein the component (a) is selected from one of a compound 4-(1H-benzimidazole-2-yl)phenyl-3-(2,2-dichlorovinyl)-2,2-dimethyl cyclopropanecarboxylate in a formula 1, N-oxide of the formula 1 and salts of the formula 1; the component (b) is selected from one in the following invertebrate pest control agents: (b1) neonicotinoids, (b2) cholinesterase inhibitors, (b3) GABA-regulated chloride ion channel blockers, (b4) sodium channel regulators, (b5) ryanicide receptor ligands, (b6) octopamine receptor ligands, (b7) nereistoxin analogues, and (b8) biological agents. The mixture and composition provided by the invention have excellent effects of controlling invertebrate pests and can serve as arthropod killing agents, and the crop production cost and environmental load can be reduced.

Description

technical field [0001] The invention relates to the field of pest control, in particular to a synergistic mixture, synergistic composition and application. Background technique [0002] Invertebrate pests harm the growth of crops, reduce crop productivity, destroy agricultural products in storage, and increase the cost of agricultural products. Therefore, controlling invertebrate pests is extremely important to improve crop yield and quality. Invertebrate pests also affect forestry production, greenhouse crops, ornamental plants, livestock, household products, public health and animal hygiene, therefore, the control of invertebrate pests in non-agronomic environments is also very important. [0003] Many products for controlling invertebrate pests are commercially available and can be used alone or as a mixture in production. However, as people pay more and more attention to the environment, it is more and more urgent to seek more economical and safer pest control composit...
