Synthetic example

[0053] The first active component compound A1 in the composition can be prepared by the following three methods.

[0054] Synthetic method 1

[0055]

[0056] Take the intermediate 2-amino-5-chloro-3-methylbenzamide (0.39g, 2.0mmol) (refer to patent WO2006062978 for synthesis) in a reaction flask containing 10ml of tetrahydrofuran, and slowly add 3-bromo-1- (3-Chloropyridin-2-yl)-1H-pyrazole-5-formyl chloride (0.70g, 2.2mmol), add 1ml triethylamine dropwise under stirring, stir at room temperature overnight, TLC detects that the reaction is complete, and removes under reduced pressure The solvent was extracted with ethyl acetate and water, the organic layer was washed twice with saturated sodium carbonate, and dried to obtain 0.83 g (1.77 mmol) of a light yellow solid with a yield of 88.5%. The melting point is 236-237°C.

Abstract

The invention discloses a pesticide composition with a synergistic effect, which comprises two active components with the weight portion ratio of between 1:100 and 100:1, wherein the first active component is selected from 3-bromo-N-[4-chloro-2-methyl-6-[amino carbonyl] phenyl]-1-(3-chloro-2-pyridyl)-1H-pyrazole-5-amide or N-oxide or a salt thereof; and the second active component is selected from any one of the following compounds with insecticidal activity: aryl pyrazoles, neonicotines, organic phosphoruses, carbamates, pyrethroids, benzoyl ureas, acylhydrazines, macrolide antibiotics, pyrroles, thioureas, Ryanicide receptor-ligands, mitochondrial electron transport inhibitors, nereistoxins, pyridalyls, indoxacarbs or Bacillus thuringiensis, or salts thereof.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides and relates to an insecticide composition. Specifically, it relates to a binary mixture composition containing pyrazole benzamide insecticides, a preparation of the composition and a method for controlling pests. Background technique [0002] Pesticides play a significant role in protecting crops from pests. Pyrazole benzamide compounds listed in patents WO2003015518, WO2003015519, CN1541063, CN1678192, etc. -1-(3-chloro-2-pyridyl)-1H-pyrazole-5-carboxamide (chlorantraniliprole, common name chlorantraniliprole) is effective to various agricultural pests, especially Lepidoptera pests such as beet armyworm, cotton bollworm , diamondback moth, rice stem borer, rice leaf roller, etc. have a good control effect, the structure of the compound is as follows: [0003] [0004] Chlorantraniliprole. [0005] Patents such as US2004209923 also reported that the compound of general formula A wit...
