Carboxyl acylamide compound and its preparing method and use

Abstract

The invention provides a carboxyl amide compound and its nontoxic salt, obtained by reaction of two compounds at 0-40 deg.C, where one compound contains 5-methyl pyrazine-2-radical, 5-methyl urea pyrilamine-1-methylene, urea pyrilamine-4-radical, coumarin-3-radical, 5-bromofuran-2-radical, quinoxaline-6-radical, 3-hydroxyl quinoxaline-2-radical, (thiophene -2-) or (indole-3-) or (imidazole-4-) ethylene, benzotriazole-5- radical, benzoimidazole-5-radical, (benzoimidazole-2-)ethyl, (2-amino thiazole-5-) or (2, 5-dioxyimidazoline-4-) methylene, or (benzo dioxypentane-5-) ethylene; and the other compound contains C1-8 alkyl, C1-8 oxyalkyl, aryl, or heteroatomic radical. It can be used to prepare disinfectant.

Description

technical field

[0001] The invention relates to a carboxamide fungicide compound and a preparation method thereof. Background technique

[0002] Since Von Schmeling discovered systemic wisterin in 1966, carboxamide fungicides have experienced more than 30 years of development. Carboxamide fungicides are still widely used in agriculture due to the slow rate of development of resistance using these fungicides. A lot of commercial carboxamide fungicides have been reported, such as Vitavax, Mebenil, Metsulfovax, Methfuroxam, Flutolanil, Triflumazid.

[0003]

[0004] However, some of these fungicides are not friendly to the environment, have toxic and side effects on humans and animals, and long-term use will cause obvious resistance to strains. Therefore, designing and synthesizing fungicides with high efficiency, low toxicity, broad spectrum, high selectivity, low residue and low resistance is an urgent problem in the current pesticide research.
