  • Novel O-quinolinylamidoxime derivatives were prepared by replacement of the carboxylic group at the 8 position of quinclorac with various amidoximes. In the flooded paddy conditions, most of the compounds show good herbicidal activity at a rate of 1 kg/ha. Some of them showed excellent herbicidal activity at a rate of 60 g/ha against barnyardgrass (Echinochloa aryicola) with good selectivity on rice. Under the two-leaf stage of barnyardgrass, most of O-quinolinylamidoximes showed good herbicidal activity, expecially compound 3c which showed excellent herbicidal activity barnyardgrass at a rate of 125 g/ha with good rice seletivity.
