Description

technical field

[0001] The invention relates to the technical field of medicinal chemistry, in particular to a thiazole-containing hydrazide compound and a preparation method and application thereof. Background technique

[0002] In recent years, plant fungi and bacteria have seriously affected the yield and quality of crops around the world. Plant fungal diseases directly cause crop yield and quality reduction, and bring huge economic losses to farmers. For example, Gibberella saubinetii is a filamentous ascomycete, which is caused by a variety of Fusarium infection and occurs on wheat. The pathogen can cause wheat seedling rot, stalk rot, stem rot and ear rot, and it brings at least 10-20% yield reduction to wheat-growing countries every year. In addition, rice bacterial blight (Xanthomonas oryzaepv.Oryzae) is a rod-shaped Gram-negative bacterium, which can cause the leaves of rice to wither and turn white, and it brings at least 10-50% of the rice-growing countries every...
