Description

technical field

[0001] The invention relates to a class of pyrimidine salicylic acid compounds and a preparation method thereof, as well as the application of the pyrimidine salicylic acid compounds in controlling weeds. Background technique

[0002] Weeds are a major hazard in agriculture and forestry. Weeds compete with crops for nutrients, water, sunlight and space, hinder the ventilation and light transmission of the field, and increase the local climate temperature. Some weeds are intermediate hosts of diseases and insect pests, which promote the occurrence of diseases and insect pests; Reduce crop yield and quality. In addition, the seeds or pollen of some weeds contain toxins, which can poison humans and animals. Therefore, herbicides are called the hot spot of pesticide chemistry research.

[0003] At present, there are many kinds of herbicides, mainly sulfonylureas, sulfonamide triazolones, imidazolinones, triazolopyrimidines, pyrimidine thiobenzoates, etc. Howe...
