Abstract

A series of N-[4-cyano-2-fluoro-5-(2-pyrimidinyloxy, 2-benzyloxy or 2-pyridinyloxy)phenyl]-3,4,5,6-tetrahydrophthalimides was synthesized, and the herbicidal activities of those deivatives were evaluated through pre- and post-emergence application under upland conditions in a greenhouse. The results showed that most compounds resulted in stronger herbicidal activity on broadleaf weeds than on grass weeds and higher through post-emergence than pre-emergence application. The N-[(4-cyano-2-fluoro-5-(2-pyrimidinyloxy) phenyl]-3,4,5,6-tetrahydrophthalimide showed the best weed control efficacy and marginal corn safety at a rate of 60 g/ha through pre-emergence application.

N-[4-Cyano-2-fluoro-5-(2-pyrimidinyloxy, 2-benzyloxy 혹은 2-pyridinyloxy)phenyl]-3,4,5,6-tetrahyophtha-limide 유도체를 합성하였고, 밭 조건에서 토양 및 경엽처리후의 제초활성을 온실에서 조사하였다. 이 화합물들의 제초효과는 토양처리보다 경엽처리에서 강하였으며, 광엽 잡초에 대한 제초활성이 화본과 잡초에 대한 활성보다 우수하였다. N-[(4-cyano-2-fluoro-5-(2-pyrimidinyloxy)phenyl]-3,4,5,6-tetrahydrophthalimide가 가장 강한 제초활성을 나타내었을 뿐 만아니라 60 g/ha 농도의 토양처리에서 옥수수에 비교적 안전하였다.
