Abstract
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.
Quinclorac의 amidoxime 유도체 3a-m을 신규합성하고 논조건에서 피의 발아전 및 2엽기에 약제를 처리하였을 때의 피에 대한 제초효과와 직파벼 및 이앙벼에 대한 안전성에 대하여 시험하였다. 피의 발아전 처리시 화합물 3a-e는 60 g/ha 처리량에서 80% 이상을 방제하고, 3f-m은 1 kg/ha에서 100% 방제효과를 보이며, 직파벼는 250 g/ha 처리량에서도 비교적 안전하였다. 2엽기 피에 대하여 3c는 250 g/ha에서 90% 방제효과를 보였으며, 벼와 피간의 선택성도 매우 좋았다.
