PREPARATION METHOD FOR NEW GREEN SULFONYLUREA-TYPE HERBICIDE WITH CONTROLLABLE SOIL DEGRADATION RATE, AND STUDY AND USE OF SAME WITH REGARD TO SOIL DEGRADATION

摘要

Provided is a sulfonylurea herbicide with a controllable soil degradation rate. The degradation rate of the sulfonylurea-type herbicide is increased by introducing an electron-donating group at the 5-position of the benzene ring moiety of sulfonylurea.
