Abstract:In order to develop new herbicidal active compounds and study the structure-activity relationship,nineteen new sulfonylurea compounds were synthesized.Their structures were confirmed via 1H NMR,MS and elemental analysis.The preliminary herbicidal activity of these new sulfonylurea compounds was determined with rape disc assay and pot bioassay experiments.The results show that most of the sulfonylureas consisting of 4,5,6-trisubstituted pyrimidines displayed a herbicidal activity at 1.5 kg/ha.
Keywords:Sulfonylurea  4  5  6-Trisubstituted pyrimidine  Herbicidal activity
