Amide compound and preparation method and application thereof

Abstract

The invention provides an amide compound and a preparation method and application thereof. The amide compound is provided with a structure shown in the formula I, has a remarkable effect on controlling diseases in agriculture and forestry and particularly has a good control effect on erysiphe cichoracearum, pseudoperonospora cubensis and phakopsora pachyrhizi; when the concentration of the amide compound is 400ppm, the control effect on the erysiphe cichoracearum is greater than or equal to 90%, and the control effect on the pseudoperonospora cubensis is greater than or equal to 90%; when theconcentration of the amide compound is 100ppm, the control effect on the phakopsora pachyrhizi is greater than or equal to 90%; and moreover, the preparation method of the amid compound is simple andefficient, large-scale production is easy, and application prospects are broad.

Description

technical field

[0001] The invention belongs to the field of agricultural fungicides, and relates to an amide compound and its preparation method and application. Background technique

[0002] The growth of plants is seriously affected by plant diseases, which leads to the reduction of crops and economic crops, resulting in economic losses. Therefore, it is of great significance to develop effective antibacterial agents against plant diseases.

[0003] Amide fungicides are a kind of commonly used fungicides, which account for a considerable proportion of fungicides. They have attracted attention for their high-efficiency biological activity. However, after a period of use of these fungicides, diseases will become resistant Therefore, there is a constant need to invent new and improved compounds and compositions with fungicidal activity.

[0004] Alkyl-substituted diphenyl ether pyrazole amides have been reported in the prior art, for example, CN103391925A discloses compound...
