Controllable Effect of Structural Modification of Sulfonylurea Herbicides on Soil Degradation

The study of soil degradation behaviors of sulfonylurea herbicides in relation to their different structural attributes is utmost important for us to comprehend the development of new eco-friendly herbicides. It is postulated that the structural modification of the chemical structures could influence their degradation rates in soil. Nine devised structures were synthesized to study their herbicidal activity as well as their soil degradation behaviors respectively. The novel compounds I-3–I-7 were characterized by UV,1H NMR and13C NMR, MS and EA. Bioassays indicated that most of target compounds displayed superior herbicidal activities in comparison with Chlorsulfuron. Soil degradation results further confirmed our previous assumption that the introduction of electron-donating substituents at 5thposition of the benzene ring distinctly increased their degradation rates, among which dimethylamino and diethylamino groups can adjust the degradation rate to a more favorable status.

Discovery and application of sulfonylurea novel structure with controllable soil degradation speed

The present invention relates to discovery and application of a sulfonylurea novel structure with controllable soil degradation speed. The structure is represented by a general formula I, wherein definition of each substituent group is shown in the specif
