| Abstract: | A series of 2-(1,3-dimethyl-4-substituted-5-pyrazolyl)sulfonylimino-5,7-disubstituted-2H-1,2,4-thiadiazolo2,3-a]pyrimidines was synthesized and tested for herbicidal effects. The compounds showed potent activity and improved selectivity to rice when compared with analogous sulfonylurea derivatives. |
