Embodiment

[0505] Now, the present invention is described with reference to Examples, but it should be understood that the present invention is not limited thereto.

[0506] First, typical examples and production examples of the compound of formula (I) are described.

preparation Embodiment 1

[0508] N-[2-bromo-4-chloro-6-[[α-methyl-(cyclopropylmethyl)amino]carbonyl]-phenyl]-3-bromo-1-(3-chloro-2-pyridine base)-1H-pyrazole-5-carboxamide (compound No. 1) preparation

[0509]To a mixed liquid containing 0.6 g of α-methyl-cyclopropylmethylamine hydrochloride and 40 ml of tetrahydrofuran, 1 g of triethylamine was slowly added dropwise under ice-cooling, followed by stirring at room temperature for 1 hour. Then slowly add 0.85g of 2-[3-bromo-1-(3-chloro-2-pyridyl)-1H-pyrazol-5-yl]-6-chloro-8-bromo-4H-3 , a mixture of 1-benzoxazin-4-one and 10ml tetrahydrofuran. After the dropwise addition was terminated, the mixed solution was reacted under reflux for 4 hours. After the reaction was completed, the solvent was distilled off under reduced pressure, and ethyl acetate and water were added to the residue for extraction. The organic layer was washed with water and a saturated aqueous sodium chloride solution, and dried by adding anhydrous magnesium sulfate. The solvent was...

preparation Embodiment 2

[0511] N-[2-bromo-4-chloro-6-[[(cyclopropylmethyl)amino]carbonyl]-phenyl]-3-bromo-1-(3-chloro-2-pyridyl)-lH- Preparation of pyrazole-5-carboxamide (compound number 2)

[0512] The desired product having a melting point of 196-199° C. was obtained in the same manner as in Preparation Example 1, except that cyclopropylmethylamine hydrochloride was used instead of α-methylcyclopropylmethylamine hydrochloride.

Abstract

A pesticidal composition comprising synergistically effective amounts of at least one anthranilamide compound represented by the formula (I) or its salt and other pesticide: wherein each of R1a and R1b which are independent of each other, is halogen; each of R2 and R3 is halogen, alkyl, haloalkyl, alkoxy, haloalkoxy or cyano; A is alkyl substituted by Y; Y is C3-4 cycloalkyl which may be substituted by at least one substituent selected from the group consisting of halogen, alkyl and haloalkyl; n is 0 or 1; and q is an integer of from 0 to 4; provided that R1a and R1b are not simultaneously chlorine nor bromine.

Description

technical field [0001] The present invention relates to an agrochemical composition comprising an anthranilamide compound of formula (I) described hereinafter or a salt thereof and other insecticides. Background technique [0002] So far, organophosphorus compounds, carbamate compounds, pyrethroid compounds, etc. have been used as active ingredients of insecticides, but as a result, some insects have developed resistance to these insecticides in recent years . Therefore, there is a need to provide insecticides that are effective against these resistant insects. [0003] An anthranilamide compound of formula (I) described below or a salt thereof is disclosed in Patent Document 1. In addition, Patent Document 2 discloses in Test A and Test C on pages 83-85 that a specific combination of anthranilamide and imidacloprid or thiamethoxam is effective against diamondback moth (diamondback moth). or aphid control effect. [0004] Patent Document 1: WO2005 / 077934 [0005] Patent...
