Definitions

  • the application belongs to the field of pesticides, and relates to a cyano-substituted benzamide compound and an application thereof.
  • Mites are a common crop pest, widely distributed all over the world, and can harm a variety of crops. Once a crop is infested by mites, it will damage the appearance of the crop, and seriously reduce the crop yield or even fail to harvest. Mites are known to be difficult to control pest communities due to their small size, rapid reproduction, small range of action, strong adaptability and easy emergence of drug resistance. In the production of crops such as agriculture and horticulture, the damage caused by pests such as mites is still very significant. The pests are resistant to the existing pesticides and the existing pesticides are not environmentally friendly. There has been a need to develop better activity and dosage. Lower, more environmentally friendly new pesticides.

螨虫是一种作物常见的虫害,广泛分布于世界各地,可以危害多种农作物,作物一旦被螨虫侵害轻者破坏作物外观,严重的能导致作物减产,甚至绝收。螨虫个体小、繁殖快、行动范围小、适应性强和易产生抗药性,是公认的难以防治的有害生物群落。在农业及园艺等作物生产中,由螨虫等害虫等引起的侵害依然非常显著,害虫对现有杀虫剂产生抗性及现有农药的环境不友好等原因,一直需要开发活性更好、用量更低、环境更友好的新杀虫剂。
氰基取代苯甲酰胺类化合物的杀虫活性已有报道,如CN108586279A公开了化合物286(KC1)、CN109497062A公开了化合物23(KC2)及其对小菜蛾、二化螟等害虫的杀虫活性,CN102119143A公开了化合物6-1125(KC3)对小菜蛾、斜纹夜蛾、家蝇等害虫的杀虫活性,但该申请中未公开此类化合物杀螨活性。
