摘  要:
[Aims] Orthosulfamuron is a pyrimidinylsulfonylurea herbicide. In order to study its derivatives, the synthetic method and herbicidal activities were explored. [Methods] Orthosulfamuron was synthesized through four steps from 2-aminobenzoic acid and 2-amino-4,6-dimethoxypyrimidine, and its structure was confirmed by 1H NMR.[Results] The test result shows that orthosulfamuron has good herbicidal activity against Abutilon theophrasti.[Conclusions] Orthosulfamuron showed potent herbicidal activities and safe to rice and wheat, it has a broad application prospects and deserves attention.
