  • New series of pyridylimidazolinorus substituted with N-(2-hydroxyethyl)-${\alpha}$-dicarbonylamide group, N-ethoxycarbonylthioamide and N-benzoylthioamide group in place of carboxyl group at 3-position of pyridine were prepared, and their herbicidal effects were tested(in vivo) in upland conditions. Most of pyridylimidazolinones substituted with hydroxydiketoamide and N-ethoxycarbonylthioamide group at 3-position of pyridine showed good herbicidal effects at a rate of 250 g/ha, while pyridylimidazolinone substituted with N-benzoylthioamide group showed no herbicidal effects.
