摘　　要：为探索10%噁嗪草酮悬浮剂在南方机插秧田的施用技术,进行了不同施药时间、施药剂量的田间小区试验。结果表明,10%噁嗪草酮悬浮剂推荐剂量为37.5~60ga.i./hm^(2)时,对稗草防效高达92.4%~97.0%,对莎草防效为76.3%~83.6%,对鸭舌草防效为76.3%~83.6%,且表现出持效期长、对机插秧水稻安全等特点,是一种兼具茎叶处理活性与封闭活性的机插秧田除草剂。In order to investigate the application technology of oxaziclomefone 10%SC against weeds in mechanized-transplanting paddy field in south of China,the field plot experiment was performed at different application time and dosage.The result showed that the control efficacy of oxaziclomefone 10%SC at recommended dosage of 37.5-60 g a.i./hm^(2) was 92.4%-97.0%,76.3%-83.6%,and 76.3%-83.6%against Echinochloa crusgalli,Monochoria vaginalis and Cyperus iria,respectively.Oxaziclomefone 10%SC had longer-duration efficacy,and was safe for rice.It is a kind of herbicide which can be used as both stem and leaf treatment agent and soil treatment agent in mechanized-transplanting paddy field.
