Problems solved by technology

Likewise, societal demands such as reductions in application quantities or rates are not adequately met
[0003] In addition, the emergence of pathogenic bacteria resistant to conventional general-purpose agricultural and horticultural fungicides is also a problem
Although pathogenic bacteria have not developed resistance to some agrochemicals, these agrochemicals usually require a large amount of application or a large amount of application, so they are unfavorable in terms of environmental pollution and other aspects

[0759] Hereinafter, the present invention will be described more specifically by referring to the synthesis examples, formulation examples and test examples of the compounds of the present invention, however, the present invention is not limited thereto in any way.

Synthetic example 1

[0761] N-{3-(Difluoromethyl)-1-methylpyrazole-4-carbonyl}-N-{2-(1,3-dimethylbutyl)phenyl}-4-methylthiadi Azole-5-carboxamide (number 1-146)

[0762] Thionyl chloride (619mg, 5.20mmol) and N,N-dimethylformamide (20mg, 0.27mmol) were added to the toluene solution of 4-methylthiadiazole-5-carboxylic acid (250mg, 1.73mmol) ( 10 mL) was heated to reflux for 2 hours, and the reaction mixture solution was concentrated to obtain 4-methylthiadiazole-5-carbonyl chloride.

[0763] The 3-(difluoromethyl)-N-{2-(1,3-dimethylbutyl)phenyl}-1-methyl-pyrazole-4-carboxamide (350mg) prepared in Reference Example 1 , 1.04 mmol) was added to a separate container containing sodium hydride (60%, 45.9 mg, 1.15 mmol) and tetrahydrofuran (2 mL), and the mixture was stirred at 25°C for 20 minutes. The tetrahydrofuran solution (2 mL) of 4-methylthiadiazole-5-carbonyl chloride prepared above was added thereto at 0°C, and the resulting mixture was stirred at 25°C for 1 hour. After confirming the completion of...

Abstract

The present invention provides: an imide derivative which is represented by general formula (1) wherein R1 is substituted by a substituent such as an isothiazolyl group, Q is substituted by a substituent such as a thiophenyl group, or A is substituted by a substituent such as a pyrazolyl group; and a bactericide for agricultural and horticultural use, which is characterized by containing this imide derivative as an active ingredient, and which exhibits excellent bactericidal effects in agricultural and horticultural fields.

Description

Technical field [0001] The present invention relates to an imide derivative that has a high control effect on various pathogens harmful to the cultivation of crops, has high safety to crops, and has excellent environmental friendliness, and an imide derivative that uses the imide derivative as an active ingredient Fungicide for agriculture and horticulture. Background technique [0002] Traditionally, in the field of agriculture and horticulture, although many agricultural and horticultural fungicides aimed at controlling various diseases have been developed and used in practice, they are not always impressive in terms of efficacy, spectrum, and residual efficacy. satisfaction. Likewise, social requirements such as reducing the number of applications or application rates have not been fully met. [0003] In addition, the emergence of pathogenic bacteria resistant to conventional general-purpose agricultural and horticultural fungicides has also become a problem. Although pathoge...
