Description

Isoindole compounds and their applications technical field The invention belongs to the field of herbicides, and in particular relates to an isoindole compound and its application. Background technique Due to the succession and change of weed populations and the emergence and rapid development of resistance to chemical pesticides, people's awareness of ecological environment protection has been continuously strengthened. The emphasis on the issue of whereabouts continues to increase. With the gradual reduction of the world's arable land, the continuous growth of the population and the increase in the demand for food, people are forced to rapidly develop agricultural production technology, improve and improve the farming system, and need to continuously invent new and improved herbicidal compounds and compositions. JP60109563 discloses that the following isoindoles have herbicidal activity: Wherein, R=Cl, Br; R1=H, F, Cl; R2=alkyl. WO8801265 discloses the following ...
