Definitions

  • the invention belongs to the field of agricultural fungicides and bactericides, and specifically relates to a pyridazinone derivative and a use thereof.
  • Plant bacterial diseases are the third largest type of plant diseases after fungal diseases and viral diseases, which are caused by bacteria infecting plants.
  • Bacterial diseases such as citrus canker, cucumber angular leaf spot, tomato bacterial wilt, rice bacterial leaf streak, and rice white leaf blight are all important diseases in the world. In my country, bacterial diseases often occur and tend to occur more frequently, with the characteristics of rapid onset, great harm, and wide distribution. Due to the long-term use of traditional bactericides such as inorganic copper preparations and antibiotics, plant pathogens have developed a certain resistance to them, and the prevention and control effect is not ideal, causing great losses to agricultural production. Therefore, the market is in urgent need of new bacterial disease control agents that are efficient, low-toxic, and environmentally friendly.

Description

一种哒嗪酮衍生物及其用途 技术领域
本发明属农用杀真菌剂、杀细菌领域,具体涉及一种哒嗪酮衍生物及其用途。
背景技术
植物细菌性病害是一种由细菌侵染植物引起的一种仅次于真菌病害和病毒病害的第三大类植物病害。如柑橘溃疡病、黄瓜角斑病、番茄青枯病、水稻细菌性条斑病、水稻白叶枯病等细菌性病害都是世界性重要病害。在我国,细菌性病害时常发生且呈偏重发生趋势,具有发病快、危害大、分布广等特点。由于传统杀细菌剂无机铜制剂和抗生素的长期使用,使得植物病原菌对其产生了一定的抗性,防治效果不理想,给农业生产造成了极大损失。因此,市场急需高效、低毒、环境友好的新型细菌性病害防治药剂。
